Fresh hacks every day
[Daniel Eindhoven] put together this 11,344 Joule capacitor bank that he says would be perfect for weapons such as a rail gun, coil gun, or electrothermal-chemical gun. He machined a couple of aluminum plates to act as a positive and negative bus. The two are separated by a denuded sheet of PCB (making us wonder how he got … Read the rest

There’s no shortage of input, with two analog sticks from a PlayStation controller, several momentary push buttons, and some toggle switches. Although … Read the rest

If you’re feeling like you want to take on a little more complicated chemistry project, you can also make the … Read the rest

He found he likes the AVR line for its ease of development under Linux, a feature … Read the rest
