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!

s/


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 :)

Thanks.

Frédéric.

Busy building my BOM on Farnell components, I might have found all required pieces. I come up to 41 EUR and need 50 to be able to order as a private customer. I need to share command with someone else in Belgium or north of France(easier to meet when command arrives)

For reference if it helps. I didn't build it yet but ready to order following :

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.

Thanks for sharing info ...

I'll check the size of the 2 "big" capacitors.

PS : any idea for the LCD display ?

Hello can you tell us which module and where you bought it from ? We might actually go for the same :)

I've also some trouble finding only one USB header ... and small details.

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.
