Wifi Clock with PCBs sponsored by PCBWay

1 de June de 202025 de June de 2022 Robson Couto Leave a comment

Some time ago, we were approached by PCBway about getting sponsored PCBs for review. I actually got pretty hyped, as I never had sent a PCB to be manufactured before. Even tough I have designed some  PCBs for milling at home, they have to be very simple. A little background, almost everything I write here […]

Welcome! In this post I talk about the reverse engineering of the GM328A transistor tester. I have drawn the schematics of the board and compiled new firmware for it. As a bonus, I also programmed Tetris for it. Intro Some time ago I wrote an article where I programmed one T3 LCR meter / transistor […]

I have recently become very interested in music. Consequently, I started to learn how to read scores. So, I thought that adapting some songs for Arduino would be a good exercise. I wrote a few Arduino sketches, with some details on mind: Sketches should be compatible with all or almost all Arduino boards; No need […]

Intro Some time ago, I was browsing some Internet when I believe I got and ad to a CNC milling machine from gearbest. It was 30% off and at time (140$, plus 40$ for shipping to Brazil) and it did seem to be a very good deal.  I ended up buying it, but why would […]

USBASP, a cheap retro controller adapter?
