A simple USB switch so I can swap a keyboard or mouse between two computers.
It is operated by 4 single mechanical switches, 1 for each channel. Simple designs can be implemented.
PCB for clipping onto Guillemot MAXI Gamer 3D Voodoo graphics accelerator. The common memory size for these cards is 4 MB. With the help of PCB you can get Voodoo up to 8 MB.
Based on ESP32, HC-SR04 ultrasonic sensor
1-layer PCB 50.1 x 79.9 mm FR-4, 1.6 mm, 1, tinned with leads, blue solder mask, white silkscreen;
This board was created for the mcudude library and has good voltage filtering, reducing reset time via a c10 capacitor (10nF!!) on the dtr line of a ch340 system. It would be nice to solder a precision socket under the x1 oscillator, it gives you the opportunity to try different frequencies (useful for rs232 communication for example)
It's common for computer users to bend over in front of a screen, which can eventually lead to back problems. There are various gadgets on the market that solve this problem by constantly reminding users to sit up straight, but most of them are not fun. So I made a fun little tool for this problem.
