After a few weeks I finally got the remaining parts in and cast a smaller bulb for the first “full prototype”
As you can see, it still has work to be done. It “almost fits” (TM) and “almost works”. Unlike with the first prototype bulb, this version does not always register the hit. It could be the switch to a 3v3 8mhz board or the cheap eBay special BMP280 breakout boards. For now it’s off to the side as I came up with an idea for a full size Project Diva touch slider PCB that I will be making in the next week or two.
