No credit because your detector is not recognized by the project. What device version is it?

Stderr output

<core_client_version>7.6.29</core_client_version>

Firmware updated ;)

Detector connected only with the programmer and:

avrdude -c usbtiny -p m88 -U flash:w:Radioactive_V2.60_FW1.1_OFFICIAL.hex


Thanks for assistance

Thank you appu
I just ordered an usbtinyisp v2 like programmer.
Do i need to power the detector via usb while programming or power should come form the programmer? There should also be a jumper in the programmer to provide the 5v or not

Well, I just bricked my detector, I can not sit still :)

Everything looked good when i clicked upload FW, the led blinking one time, progress bar, but Radioactive@home never came back in the display.
Any advice? What I need to flash the firmware in other way?

I looked at avrdude installed on my debian pc. Can I use it with the usb to ttl adapter or do I need anything else?

Thanks

I don't know if it is really needed but I see a missing soldering in the transformer. It's one of the three near the mounting hole that is connected to the circuit

DZ4 is probably in the backside due to a problem with the design of this board. See here
http://radioactiveathome.org/boinc/forum_thread.php?id=219&nowrap=true#2596

I would test R12 and R18 (the two 5.1 MOhm under the tube) because they should be 0.6 W resistors and seems they are 1/4 W instead

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.


Problem already solved here

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?

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"


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...



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


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

I will try another expander/display

Thanks
