Sourcing or replacing the dome button

[emosenkis]

I'd like to try building a few of these as a SMD practice project but I'm not sure what to do about the dome button, which is listed in the BOM as 'custom'. I found a reference to Snaptron BL10280 but I'm not sure if that's actually the right part or if they'll accept an order for a very small number of parts. Is there a standard (e.g. available on Digikey) part that I could substitute that would match the footprint and pads? Would it work to simply replace the dome with a copper pour and treat it in software as a capacitative touch button or would that require further modification of the PCB or additional components?

Unfortunately the capacitive touch method won't work with the current PCB. You could edit the firmware to ignore the button, or get a sample of Snaptron's BL series. Very likely one of them could fit. If you're considering something more serious, we can connect you with the official button.

Cool stuff @emosenkis! If you build some, would be interesting to read a blog post on your experience, perhaps we could share appropriately if you're interested.

Hey, if you could hook me up with the official button I would be so grateful.
