Making A Pickit 3 Clone

After using the Microchip tools to program and debug the projects I work on, I wondered about creating my own programming/debugging module that I could put on my own boards – just like Microchip does with their starter kits and such. As I became more interested in that idea, I began to search the web to see if anyone else had already done something similar. Initially, I found lots of posts regarding the 2nd ...

Fascinating Details of Waveshare E-Paper Displays

I have used E-Ink displays in projects three years ago, but from that time the technology has greatly evolved. That time displays were hard to get, expensive and difficult to use. Now things seem to change with e-ink displays available to the maker market :-). I’m able to get a 128×296 pixel e-paper display for $10! And for little more money I can have displays with black/white/red colors! Waveshare When I ...
