Default Re: New tool to find short capacitors on motherboards : shorty with display

Hi Kripton
The AD8628 come in two package types, SOP-8 (which is cheaper) or SOT23-5

I think form your pics you are using SOP-8. Can you confirm that is the correct one for your pcb?

Cheers

Ugh. Now I have to deal with threads on a tiny mcu. I think I'll pass on this one for a while, I'm pretty bought into the stm32 ecosystem. Speaking of which, I think this was recently released, it's a version of the blue pill with stm32f4 processor, usb c, and space for a flash chip on the underside. I might grab a few.

i'v seen the F411 blackpill,
but you may as well spend a bit more for a nucleo64 with the chip on.
then you get more i/o and an st-link programmer/debugger module.

@dicky96
yes I use the ad8628 in the sop-8 package for my pcb. (and the mcp3421 in sot23-6)
anyway as I will publish the kicad files (schematic and pcb) once the pcb is ok
you will be able to change the package if you need it.

Thanks kripton - I wanted to order the components I don't have in stock so they are here on the slow boat from china by the time your PCB is ready. Really it's just the AD8628, MCP3421, OLED display and Arduino nano I need to get. Everything else I think I have.

Will you be offering this in kit form if so what do you think the cost would be

Thanks again

sorry only bare pcb for now. may be later a smd-only populated pcb if there is interest.
you should be able to get all the components for less than $20

Hy, there is my 'producat' or copy of Kripton2035/Shorty with little modifications/add , hardware an sofware. I replace AD8628
with LTC 1050 and work fine. From five of LTC1050 , only one give good results of measurement - offer high precision on low ohm value or high ohm value on this device. I used Atmega328, not Arduino. Have fun with work !
For me was, a lot!

What would the cost of a unpopulated board plus shipping cost

nice to see other variations around my project !

the pcb is ready to send to manufacture (for prototype and test only). should receive it in 2 weeks. then test it and if it is ok manufacture in greater qty.
it should cost EUR 10 with untracked shipping, and EUR 15 with tracking.
there will be an order button on my pcb page of the project.

for now, the last variation of the pcb.

OK I'm ready to buy once you have the PCB available. Thanks
