This project has been a small and simple serially controlled biasable current source on standard 2 layer FR4 (1.6mm) and HASL with lead finish. Most parts had been DHT, a single SMD part (MSOP-8). As ...
This project has been a simple USB to TTL/RS485 interface board utilizing the CP2102N chipset. It contains a TVS diode array / ESD suppressor for inpuit protection on the USB port, the CP2102N, TTL ou...
This has been a simple interface for a bunch of 12V capactivie sensors to 5V AVR logic and IRF540N MosFETs to switch some inductive loads using the same microcontroller - only a number of resistors, d...
This board has been a simple carrier board for two external DRV8825 daughter boards and an ATMega328P to be used as an dual stepper driver that can be controlled via I2C. The PCBs (though not containi...
The project had been a simple breakout board for an D14-363GY-123 cathode ray tube that has been used in a quantum physics experiment as improvised and very cheap electron gun (by being cut open). The...
This project had been a small carrier board for some higher power LEDs to sidepump an Nd:YAG rod. This had been my first Aluminum PCB so I made some design mistakes (not enough spacing between traces ...
