Yesterday I assembled the Wac0m RipOff BLE edition (video coming soon). finally I can finish this project. It’s turned out that the BLE version is lighter than my USB version (well, this time I used less plywood board than before). The Hackaday.io project is available here (plus link to GitHub). And here are some pics I took !
This is what it looks like from the top.This is what underneath the surface, top left corner there are battery charger circuit, WT51822 module and battery.Take a look a bit closer to the circuitries.
