DEAD BUG ARDUINO IS LIVELY AND SHIELD-COMPATIBLE
Microcontroller demo boards such as the Arduino UNO are ubiquitous on Hackaday as the brains of many a project which inevitably does something impressive or unusual. Sometime someone builds a particularly tiny demo board, or an impressively large one. In the case of the board featured here, the Arduino is a gorgeous labor of love which can’t really be called a board since there is no PCB. Instead of the traditional fiberglass, [Jiří Praus] formed brass bars into the circuitry and held it together with solder.
This kind of dedication to a project leaves an impression. His notes show he saw the barest way to operate an ATMega328, built it, tested, and moved on to the power supply to make it self-sustaining, then onto the communication circuit, and finally the lights. The video below shows a fully-functional Arduino happily running the blink program. He plans to encase the brass portion in resin to toughen it up and presumably keep every bump from causing a short circuit. The components are in the same position due to a custom jig which means a standard shield will fit right into place.
