Given we might not have provided address info, in the paypal we paid with, will you be asking for addresses when it's ready to ship? Naturally, we wouldn't want to go posting our street addresses online, especially as the forum posts are Google searchable.

All we'd need is for some advertising firm, (you know, like all those pesky spammers, or the snail mail equivalents) to do a little web crawling through Google or the like, to come up with a list of addresses, to add to their junk mail files. The post office delivers enough junk mail, just with all the shopper newspapers and the like they litter everyone's mailbox with, in town here :o

Hi,
looking forward to the kit!

Is the list of parts we will have to buy you posted earlier (https://dl.dropboxusercontent.com/u/27006170/Radioactive/KIT/Rad2.60_preliminary_BOM.ods) already the final version? Or will you post it when you are done?

Does the V2.60 detector work ok with Rpi and similar small boards running Linux variants?

Why are you complaining? Have you red his post here? Otherwise you would know that shippment was planned for March...
And at the end of this post you'll find some informations on the progress.

I'm still waiting for transformers ordered a month ago :/
PCB production not yet started because I don't have 100% sureness that transformers will fit into (I don't want to pay twice and wasting time if something goes wrong). Because PCB project isn't finished I can't order enclosures.

If something will change I'll post about!

Uhh yeah dude I've seen them - my name is on the list of paid sensors. The idea of this project is a good one and may even be useful in the long run but this guy is in way over his head and seems to be juggling one too many balls in the air. He's been at it for 3 years and still hasn't got his act together. Every milestone he thinks he accomplishes is accompanied by weeks or months of waiting for something else or the parts aren't in or the dog ate his homework. If I didn't already have 20 euros in it I'd just bail and not care.

I got my earthquake sensor 4 days after I ordered and paid for it - those folks have their act together, are prepared and are always in step with what they say they are doing. That's pretty much why I'm complaining - hope that helps.

Message 2350 - Posted: 13 Feb 2014 | 10:54:28 UTC

I tell you that there are two different designs of detectors made at two different microcontrollers (Atmega & PIC) by two different persons living 400km from each other and making all of it after hours.
One of detector design (V3) was chosen to be in force, but collegue who produce this are so busy in his job that he can't do it. I also don't have so much time to produce ready to go detectors, so I decided to redesign the old (V2) one and sell it as a KIT just to get the new detectors for the project.
So I'm sorry that it takes so long. Maybe next batch can be shorten to a month or less because all of things will be checked and ready for production.

Ahem, he did communicate... What I remember was we were looking at around a March time frame. He was ordering components which were coming in (also communicated), and the time it would take to ship those from the respective manufacturers would also be somewhat out of his control.

Finally, he needs time to build, and then test to make sure everything is OK... Surely you don't think that hardware, or software development takes just a day, right? I'm sure the person assembling them also has a day job....

I will also add - the people organizing this, as well as the participating grid of users are volunteers. Their approach to date appears to be keeping the devices as affordable as possible. It is true that they could be mass produced as a more complete unit, but the price would also increase accordingly.

I do not think is the case to be so aggressive. If you had read it right, you knew that it would take as long as necessary. I've been waiting two years. For now I bought a GMC300-E. As soon as the kit will be shipped to me and it will come, i build it and I will always be grateful for the work done voluntarily by TJM and Szopler

Thank you all for your input and commentary. However you all make my point perfectly - this project is being run in an amateurish pat time way. Compare this project to any number of other ones in which you may be participating - SETI, Rosetta, Folding, Einstein, etc. - they are all run professionally, without major delays and little or no excuses or litanies of explanations as to why things just aren't or can't be happening. Adios to a project that could have been a good one but was ill-prepared to start when it did. Peace.

I have noticed that in the part list is I2C expander for LCD. Also there is note:

I2C Expander for LCD (slightly modified, mechanical compatibility only with type shown here)


I am not sure what expanders are compatible. For example this set of LCD and expander is OK?

And of course, those projects, aside from in many cases being funded by, and in large measure facilitated by university departments, like UC Berkley, Stanford, or by companies themselves; do not require one to have specialized hardware. Naturally one would have to purchase or assemble a computer to load BOINC onto, and run, which would be the user's responsibility.

But by all means, go to even a corporate entity, and PRE-ORDER something that hasn't even been released yet, and see exactly how fast it will come, when it's still in development. This could be from as of yet unreleased hardware, to operating systems (hello, Windows 95 anyone?), computer games, and other pieces of software. Gee, all those people who pre-ordered WoW: Burning Crusade didn't make this much of a fuss, when Blizzard didn't get it out in October or November 2006, and they had to wait until January 20, 2007, because the release date slipped. And that was actually a delay, this is not, as we're still within the time frame originally communicated for shipments.

Here's an idea though, if the prospect of waiting for an order to be shipped out bothers you, then perhaps it's best to not pre-order stuff? Or if you were to go on Dell's site for instance, and they gave you an estimated ship date that was a month down the road due to back orders, would you begin calling to and begin complaining with their own support representatives that your order hasn't shipped, even though an estimated ship by date was provided on their site/page which was used to place the order? Oh well, and aidios, if that's your choice...

It will work with USB Host with Linux/Windows OS's on board so with RPi also.


What would be the best way to order the parts required once a final BOM is determined?
Also interested to know if the enclosure is designed for the LCD dimensions in the preliminary BOM?

Can I use 8 bit expander with one i2c address (display will use lower 4 bit for adresing) or is neccessary to use 16 bit expander with two banks?

And which is the i2c adress like?

It's OK with me, if things get delayed a bit... There's plenty going on in your part of the world right now, and for that lets just say that I follow the news. I'm aware of what's transpiring in the Ukraine right about now, and as that's right on your? (Poland's) border, and not knowing exactly where your supplies come from, can understand if this might have a bit of an effect on the shipping over there...

One thing that will be very helpful of course, once the kit arrives, and something that many kits do come with, is an included set of directions that walks people through the assembly, while also providing parts needed, etc.

This way, as long as people can follow a step by step set of directions, they will be able to assemble it, and all...

Thats great to read from you.

I think it shpuld not be a problem to assemble it when we have all parts.
Most parts are unique and have her place. The rest is numbered and so it should be clear whre they go.

When its ready i think is the important moment when we boot it first time ;-)

Have a good Time

Do we need to buy some electronic parts for final assembly on ourselves?
Do we have to solder some of the parts during assembly?

Probably tommorow producer will send me a PCB.
We have a delay in enclosures production due to error in second sample (shown at photos below). Producer must verify cnc code before he will produce whole batch.

Hmm, that will be interesting, as I don't have a soldering gun where I live, in apartment now, and all that, far from the living arrangements I was in, in years past.

I could probably buy one as long as it isn't too expensive, just need to find a way to do it, where things won't prove too messy wrt a move out inspection down the road. Perhaps if I move the microwave off the kitchen counter, to make some room there... Unless it's possible to use clamps/clips in some of the places one would otherwise solder, in which case I could do it at my desk. Just wouldn't want to end up melting mettle onto the thing. It's a rather expensive wooden desk. Also don't have any garage or basement space where I live anymore...

I would like to order for a Kit or a ready interface, like some of us I assume.
Wouldn't it be a good idea to be able to subscribe somewhere on a wait list and get a regular status update online: waiting, now you have to pay, paid, waiting for parts, assembled, ready to be delivered,...etc

I know that you are doing your best, just trying to streamline this a bit more.

I had created once a form for subscribing (or pre-ordering). Unfortunately for more than 300 people only about 80 from this list order detector when we ask for money to make it...
Especially now, I don't know when next batch will be organised so is no sense to do this list at the moment...
Anyway, every time when we organise pre-order, we inform about it on web site, forum and even BOINC Manager display info in Notices tab.

Might not be best idea, last batch was 27 euros? Though that wasn't a black box kit... When they have a design, supplier, and all, they'll know what the cost to them will be.

tbh, everyone there has their hands full, not only with their own lives, but the geo-political situation. Putin has Poland very nervous now, due to the events in the Crimea, and also a past incursion into Georgia. Needless to say, though this isn't really a news site, they're looking to advance their plans of installing a missile shield, having moved plans ahead for settling on a supplier to build it for them. They could probably tell you more, and largely from experience, if they cared. If I was living there, I'd have a lot on my mind as well, which would leave me feeling a bit uncertain, tbh, for myself.

In any case, it has tended to be awhile between batches, and a new reference design could leave it a bit different, especially if they're able to go back to white tube v3 detectors in the next batch. It does mean not knowing when one will be able to get a detector, but it's advisable to keep an eye on this project periodically to see if the ordering has opened up ;)

@Szopler:
I guess the three additional kits have been allocated. I do not see the message that concern them.?
Can you confirm that?

It hasn't been allocated because I realized that I don't have three additional transformers. This three kits will be added to the next batch.

Is there any technical difference between this badge of KIT and the batch before or is it just a layout thing (box than tube)?

Yes, this is considered a different version than previous sensors, with more design reviews and considerations than just the package format.

In your opinion, what is the most economical way to order the various parts (as listed in the BOM) needed for this kit? Overall it is a small volume of parts required, and I don't happen to have any on hand. You can PM me specific links or sites. I'm located in Canada.

I've seen some complaints about the amount of time and the 'professionalism' of this project. I want people to understand that this sensor is not an off the shelf item that can be commonly found on the Internet. Building a radiation detector and marrying it to a computer interface for a worldwide monitoring network is very new.

The comparison of this project and the QCN (Quake Capture Network) is not a good comparison. Seismic sensors or accelerometers are a more advanced technology in the marketplace and do not require the more complicated hardware of a radiation sensor.

A radiation sensor requires a Geiger-Mueller tube and a high voltage power supply needed to operate it. There is also a pulse detection circuit and additional electronics needed to interface it to a computer. This is a much more complicated project and is still mostly experimental. There will probably be some modifications and updates to refine the design to make it easier to build and more reliable and accurate.

The seismic sensor of the QCN project is already a fairly mature technology and is only about the size of a small Post-It note pad with a cable connected to it. Some of those sensors are given out free because they are subsidized. This project is probably done under different financial circumstances and is done from a country that has a more restricted access to the needed parts.

The data obtained from this network will likely be mostly background radiation levels and will detect a rare radiation incident and its spread. That doesn't happen very often, but it can be catastrophic when it does happen as seen with the incident in Japan. The seismic network will detect more frequent occurrences of earthquakes, but a worldwide system to detect radiation fallout is needed too.

Hello and thanks for the kit, arrived yesterday !

One small remark for builders, the transfo is not marked on primary vs. secondary on the PCB. Check the plans to mount it the right way.

I'll get all extra pieces needed and try to post a picture with it mounted or someone else can do if quicker ... :)

Good Luck for building the kit.
Cheers,

Frédéric.

I received my kit a few days ago but I have several questions related to Radioactive@Home Kit BOM .
For C1,C4,C5,C6,C7,C14 and C16 capacitor of 100 nF capacity , is it possible to replace them by MKT type one instead of monolithic ?
Is it possible too to put ceramic monolithic ones ?
Which voltage is needed ?

You can use MKT or even ceramic ones. It should be marked for voltage not less than 6.3V.

At schematic we have DZ4 connected to R9 and 6th pin of LM358 but at PCB it is connected to 1st pin of LM358 & 14th pin of microcontroller.

Transformer has pin numbers marked at its reel and pin 1 should be oriented to "TR1" at the PCB as shown below:

By the way,

this: 2 ST x 459097 KONDENS. MKS4 0,22µF 630VDC 20%

Kondensator does not fit.
The dimension are to big. The width is aprox.1mm to much.
In my KIT only one of this have room :-(. I am testing a second version.

The second problem is the space for the geiger tube, if you try to solder both
capacitors, you bending the geiger tube....

next message, if i fixed this problem

greetings
Holger

by the way, i use also Reichelt for buying components ;-)

Hi blaugrau,

thats not nice that they are so big.

I dont Order by reichelt.de because they dont had all Parts availibel as i want to buy them.

I have here an Kondensator that fits in there but its not the right one.

Its an older part from other orders.

If i recice my Part I look how bid my Kondentator is.

Hello again, after some check on the data sheet, the capacitor I choose (Farnell ref: 2112870)
is even wider then yours (conrad ref: 459097): 9mm thick instead of 8mm for the one on Conrad.

Thanks !

PS :

VISHAY BC COMPONENTS - BFC233922224 - CAP, FILM, PP, 220NF, 630V, RAD ref Farnell 1413839 is only 7mm thick.

First Test are negative :-( (I think this is normal...)

DZ4 is located on the backside, also the second capacitor (for testing only)



The LCD is a QC 1602A, maybe does not fit. I can only see one line without any character



No oscillator pulse are seeing on the oscilloscope, also no HV.

This LCD will never works because it has no I2C bus. It is HD44780 compatible LCD so you need an I2C expander and connect it to 'DISP_1'.

No. It should start without LCD.
About 3s after connection to the USB a new HID device should appear in device manager.

It should control display in cycle: display and backlight on / display on & backlight off / all off.
Can you show us photos of your expander and write exact display type?

*Solved*

Backlight was shining if I shorted with wire pin 2(VDD) and 15(+backlight). Then I try connect another display with another expander and it works. I probably damaged expander during assembling.

I have a question:

If i read the scheme correctly I can replace the two 5.1M resistors with one 10M and one 200K. This could be a shopping list optimization because both these resistors are already in the list. Is it right?

Not really, resistors have their max voltage limit. With two 5.1M resistors the voltage across them splits in half. If you change them to 10M and 200k, the first one will work at nearly 400V which is probably far out of spec for a resistor of this size.

Yes, the 10M I found are rated 350V.

Hi folks,

I have a question or two.

1. Do C10 and C13 have to be polymer? What about ceramics? Here's a bunch that are actually quite small: http://tinyurl.com/kitc10c13
2. Does D2 have to be ultra-fast?
3. What are the exact functions for each switch? I ask because on some of my detectors I won't be using the display nor the buzzer
4. What are the mechanical spacers for?
5. Is there a need for R10, R11, R13, R19 and R20 to be rated at 0.6W? I can understand the need for 1% but not 0.6W.

Thanks!

1) Ekhm... Not tested with another type of capacitors but should work well.
2) D2 must be fast because PWM frequency is about 39kHz
3) Left switch does nothing (but I encourage to develop existing firmware), Center - changes display settings (disp on,backlight on/disp on,backlight off/all off), Right - changes indicators (buzz/buzz+led/led/off).
4) Mechanical spacers are for display mounting
5) There is no need for 0.6W but it was simpler for me to buy than 0.4W (or less).

KIT definition:
- PCB
- Geiger tube
- Enclosure
- Programmed µP
- Transformer for high voltage generating

So you must buy all the another parts like capacitors, resistors, connectors, display and so on.

Right - changes indicators (buzz/buzz+led/led/off).

If the System show 0,00 µSv maybe the HV Voltage dont work
Check the solderpoints.
The Geigertube have a + side.
Is the Transformer correct solderd

@Tamara: Is primary winding of your transformer broken? It looks a little bit strange at this photo.

@Karikola: You can't kill ATmega in this way. What is the exact model of LCD you have? If you have display connected you can press center button few times -> Center - changes display settings (disp on,backlight on/disp on,backlight off/all off). Did you have any measuring devices?

Hi Szopler,

LCD Display is SainSmart IIC/I2C/TWL 1602 with Expander solderd
T2 is solderd
R3/R4 are not mounted

on Atmel pin 9/10 I measured 20 Mhz
but no PWM Puls at pin 5 so T3 is not working so i have no HV
DZ 4 ist correct.
When i connected to USB Port the device Manager have no reaction.
What is the funtion from Atmel pin pin 15/16?
Maybe I need CS ( chip select ) for starting ?
My mess equipment is a Multimeter and somtimes a Oszi.

Tomorro morning I will try the switch in the middle.

thanks with greetings

Hi Steve,

did you try this type of capacitors, I've big issues trying to get small parts,

As said above, I ordered parts that are 7mm thick which is better then the 8 mm specified above but even these ones are not fitting.

I've seen the X7R from AVX company but they are sold at about 45 EUR (about 65 USD) each plus 30 USD transport back here in Belgium.

For this price I order them by you and you'll have a couple of beer on my account :)

Hi, first to the DZ4 i have solder it the way like shown at schematic.

@Szlopler, i will mesure how much volts are there but i dont have a multimeter here.



Can we have so discussion about DZ4?

The PCB layout is wrong - the cathode of DZ4 is connected to PULSE (pin 14 of IC1 / pin 1 of IC2) - and it should be connected to pin 6 of IC2. I have soldered mine on the underside of the PCD but this isn't ideal.

If the zener is soldered as per the layout, it doesn't actually do anything because the output of IC2 can't exceed VCC and that's OK for IC1. But... the inverting input of IC2b is no longer protected by that zener. I can't remember what internal protections the LM358 has so my concern is the long term effect of having no protection on that input - which is coming from the geiger tube.

Any comments?

Hello Tamara,
which device (i.e.Multimeter) you have used for measuring hv voltage?

Normal multimeter have 10 Mohm as input resistance.

Maybe the input resistance make this effect, because (maybe) the source have
not enough power to drive the geiger tube and your multimeter.

Hello Tamara,
which device (i.e.Multimeter) you have used for measuring hv voltage?

Normal multimeter have 10 Mohm as input resistance.

Maybe the input resistance make this effect, because (maybe) the source have
not enough power to drive the geiger tube and your multimeter.

greetings



It was an normal Multimeter.
But when i have a voltage it should work.
So its not the transformer....

Voltages looks OK so if detector still shows 0.00 then probably the tube is dead.
You can check if processor counts pulses form tube by connecting (with an insulated wire) few times (+) and (-) of tube connectors.

Hi all,

sometimes after restart of my raspberry, detector reports:

Detached driver: usbhid
claimed interface, No error,0

These values are wrong. Detector display shows correct values. It's the first value only, next values are ok.

Next I have big problem with usb comunication:

Warning: cannot query manufacturer for device: error sending control message: Broken pipe


Only restart of raspi helps. I have QCN sensor connected to the same raspi and it works ok a lot of moths.

Where should be the problem?

PS: @Tamara - stupid question: did you check polarity of geiger tube?

I have finished to build the detector but it doesn't works. I have a display with i2c expander and I think the display is broken. Should the detector start if the expander is good but not the display?

It should start without Display, startup delay is about 3sec.

My first thought was also that the system doesn't work, because the Display shows only the black-Char Bars - native I2C Display from Winstar.
I measured the 20 Mhz Freq - OK
also took a look on the TxD from the ATMega - there was traffic.

After some time i found the mistake.
My Display had on Pin 15 (Vee on the Schematic) a negative Vcc Output. This pin is connected with the 10k Poti for the contrast. So the contrast dind't go over 0 Volt and was always black.
I disabled / removed the negative Vee Output from the Display and make a bridge with 10 Ohm in serie to Vcc.
After setting the contrast the display works fine, also the backlight.

A couple of dumb questions:

R2,R4: I have not put them because I have the expander. Are them absolutely needless?

Like "C1, C4, C5, C6, C7, C14, C16" those are also monolithic. Should be a default Ceramic Cap (MLCC).
A short sentence from the EN Wikipedia "It was an American company in the midst of the Apollo program, launched in 1961, pioneered the stacking of multiple discs to create a monolithic block. This “multi-layer ceramic capacitor” (MLCC) was compact and offered high-capacitance capacitors"


R2,R4: I have not put them because I have the expander. Are them absolutely needless?

You mean R3 & R4 ? These are pull-ups for SCL & SDA and should be already placed on your I2C Expander. Also don't mount VR1 & T2

Detector should start after 3s delay caused by bootloader. If you have an RS-232 adapter (voltage converter from PC RS232 <to> TTL) you should receive in terminal (Connection params.: 9600,8,N,1) some '?' for first 3 seconds and then every single second a number of pulses detected in last 35 sec.

Pin 15 has double function. If you have LCD with native I2C it controls LCD Backlight (on/off) or you can (if you change firmware) use this pin as you like.
Pin 16 has no function and as same as 15 by changing firmware it can be use for user purposes.

Can I use 0.25W resistors for R8 - R20?
Or maybe 5% is enough for R8 - R20?

Well, the one I used for C11 is a 500V 20%. I got later a monolithic 100V 10%. Don't know if it's worth to change it...

Yes it was R3 and I had done all as you say.

I will try another expander/display

If you have a -200V and the winding of the transformer are reversed then you solder the transformer from the bottom of the PCB ;-)


Kidding aside...
but i would say you have placed D2 in the wrong direction. Its a simply Diode Bridge which will let only the postive Voltage thru the Diode (if its placed right). Check the direction of the Diode D2. The Kathode Mark on the Diode should be point / soldered to C13 - Anode to the transformer

Please check everything 3 times and if there are reversed winding - cut two paths at the primary side and connect it across with insulated wire. Something like:

It is recommended to use 1% resistors even with lower wattage. But if you have problems with buying it you can use 5%.

As I have impediments finding some of the parts I desided to check how many detectors have been assembled.

Only 33 sensors (v2.60) have ever sent measurents out of 200.



Not so many...

First, thank you for this gread Kit. Now I have all needed parts and started with assembling.

I've ordered an HD44780 compatible 1602 LCD and an I²C expander. The display works fine with an arduino setup and the expander has an address range from 0x20 to 0x27 (default 0x27). I've looked in the sources for v2.60 and it seems you start to search from address 0x40 up to 0x7f. Is this the same binary which is pre-installed on the atmega88? Do I need to recompile and update the firmware to get the display working?

Greets jtf

PS: If anybody needs some C10, C13, i have six left. (220nF, 630V 224J, RM15)
ca. 17x13x7mm. I've decide to solder C13 normally and C10 "flying" between R5 and display with heat shrink tube.
They look like them http://www.aliexpress.com/item/100pcs-Polypropylene-Capacitors-224J-224-0-22uf-220nf-630V-CBB-Capacitor-Free-Shipping/504379938.html

Hi,

I've assembled first sensor. But it does not work.
Could you please advice how to debug it?

When I plug it in the buzzer beeps shortly and LCD shows blank symbols.



Nothing else happens. PC doesn't show any connected USB devices.

I measure 5V at 7(VCC) and 8(GRD) pins of the controller,
but 0 Volts at C9.
0V is also at c10 and c13.

What are the proper steps to debug it?

Shall I try to read RS232? What will it give me? Presence of I2C data exchange?

I have standard multimiter. What are the key points to check at the PCB?

For that moment bootloader is a feature to use in future for firmware upgrade purposes. I have program which allows to upload FW via bootloader but it has commercial license. We must write our software to use this in our project.

You must upload firmware via ISP connector (\Release\Radioactive_V2.60.hex).

0x04 for Extended FUSE shouldn't exist.

Boot sequence at RS232 looks like:
1) some '?' (for about 3 seconds) came from bootloader
2) "Radioactive@Home V2.60"
"Firmware 1.0 (27.03.14)"
3) number of pulses counted in last 35 seconds (new value every second)

Try to run it without LCD and check what happens then.

I'm little confused with reading RS232.

How should I connect 1,2,3,4 holes at the PCB with the 9-pin RS232



I connect
[PCB hole <- pin name at the pic]
2 <- TD
3 <- RD
4 <- Signal GND

and leave hole 1 unconnected (as the PCB is powered by MiniUSB connector)

Is my connection right?

With this connection I read the Serial port but nothing comes from the sensor when I attach MiniUSB to the PCB to supply with power.

Hi My two V2.60 kits work very well thank you.I notice that the second function switch blanks out the display and the third one switches on the speaker. My question is: what does the first switch (one the left) do? Thanks.

Hi!

I just finish to assembly a 2.60 kit, and I've got a problem.
The display show 0,00µSv/h everytime.
The Geiger tube is OK, I tested it in my old detector.
The voltages look good (190V around the tube, and 380V on the transfo).

The task returns:

Stderr output

<core_client_version>7.0.27</core_client_version>
<![CDATA[
<stderr_txt>
nding control message: Broken pipe
Warning: cannot query manufacturer for device: error sending control message: Broken pipe
Warning: cannot query manufacturer for device: error sending control message: Broken pipe
....


I don't think I made a mistake, so I don't know what to do now.

Greeting from France.

So if tube is ok then must be something wrong with pulse forming section.
Unsolder IC2, take a wire and connect pin 14 of uC to gnd few times to simulate pulses. LED should blink at every pulse. If it blinks then check pulse forming section - I mean C9,R9 and IC2 with surrounding elements...

Well, I found a bad weld on a GND pin on IC2. Then, the detector show the same µSv/h rate than my first detector.
Thank you very much Szopler for your good intuition.

But now, the UT returns again the same message :

<core_client_version>7.0.27</core_client_version>
<![CDATA[

And the credit is 0.00 ...

I use a Raspi, and it works correctly with my first detector, so I don't know what to do?

Hello,

With the help of my AF's friend Elgrande, I found a problem with my kits.


§ lsusb -v -d 16c0:05df | grep 'iManufacturer'
§ iManufacturer 1
§ lsusb -v -d 16c0:05df | grep 'iProduct'
§ iProduct 2


Why I don't have a Manufacturer and a Product names?
Is it the reason why all WUs return
Warning: cannot query manufacturer for device: error sending control message: Broken pipe
??

Thank you to help me.

Hi!

Always with the trouble with my two 2.60 kits.

Question to the specialists...
If I upgrade the firmware, is the problem will be resolved?

You should first check that R5,R6,R7 and Dz2,Dz3 are correctly soldered because it looks like not working or working wrong USB connection.

Hi Szopler!

I checked in static, with an Ohmmeter, the continuity between USB and R5, R6, R7, Dz2, Dz3, IC1 pins 4 6 and 11, and it looks good. I didn't find any trouble.
I made my test with an USB cordless plugged.

What else?

if the sensor seen in the system correctly, install the driver for Linux libusb-dev.

Tonight I found the courage to watch at my sensor lying there. Searching for mistakes and finding nothing evident I decided to try soldering R3 and R4 which according to the manual are not needed unless you use the native i2c display.

Connecting the cable i found with surprise the sensor is working.

I'm not inclined to belive the seasoning has benefited XD. Are you pretty sure R3 and R4 are really not needed for the detector to start?

Same problem as cottesloe in Fedora (not tried yet on the raspberry pi).
Seems to me a permissions problem. I tried changing the group of the device in /dev/bus/usb to boinc (the user on witch BOINC run) and the device has been detected from radioactive.

I will test if it is consistent ant then probably try to make an udev rule.

I finally got around soldering the kit together

Now it does not work i rechecked all the welds, the unit is running without a display

There is only 2 to 3 volts on the tube all the 5v rail looks good.

It looks like i am missing R19 it was nog soldered BOM said i should be delivered.

Serial output only gives ???????? i tried to re-flash the bin file and reset the fuses this all did not help to much

After some more fiddeling around i found out that i am unable to set the EFuse to 0xFC
avrdude: verification error, first mismatch at byte 0x0000
0xfc != 0x04

please help me

Is it a v2.60 or 2.61 kit? Could you post a photograph of it so we can have a look and see if anyone can spot anything wrong? If it's a 2.61 kit, then yes, R19 (33k) was missing and you will need it, but there should still be more than 3V on the tube, even without it. There may be something else wrong. Photo would be helpful.

Ok, same v2.61 kit as mine. I just put a voltmeter across my GM tube and am reading a steady 192V, it's not dropping off. Interestingly, while the voltmeter is connected, the tube stops working (reading falls to zero counts). It picked up again once I took the voltmeter off.
What are you using for C9? Looks like 2 capacitors in parallel? Is it (or are they) rated at 500V or more?

C9 is 2 68pF 500v caps in series to make around 22pf still waiting for the 22pf C's to be delivered.

The tube seems fine when booting after that it stops working and the voltage goes down to 2 volts.

The software i am running is also 2.61 btw

I can't spot anything wrong. If you take your voltmeter off the tube for a few seconds and then put it back on, does the voltage go back up and then fall again, or stay low?

It stays low only a reset of the MCU brings back the voltage.

The AVR controller regulates the high voltage for the tube using PWM based on feedback through a voltage divider. Perhaps the 2 68pF in series are closer to 34pF total, and the firmware can't reach the right value so it eventually gives up for safety reasons. If you don't expect the 22pF soon, maybe try 3 68pF in series; this should be very close to 23pF.

Getting closer to the issues but no fix yet, it looks like the ADC is having problems

if i measure the ADC0 its around 2.4 volt but when i print the value to the serial line its 1023
