Mikkel says, “The C64 USB keyboard connectos to a PC and is detected as a USB HID device. It uses Objective Development’s AVR-USB firmware only driver on an Atmel ATmega8. The microcontroller takes care of scanning the keyboard matrix of an old Commodore 64 “breadbox” and debouncing and converting keypresses to USB HID reports. Should […]
I visited the computer museum at RE/PC recently and took a walk down memory lane. Since I played “Wizardry” for about three years from the age of 10-12, old computers make me feel all soft, fuzzy, and nostalgic. What old computers do you have fond memories of? Photoset link.
I have always wanted to try this! 1. Get a pickle. 2. Jam electrical wires into opposite ends of said pickle. 3. Plug wires into AC socket. Notice, “Plug in…” comes LAST! Keep in mind, you are dealing with LIVE AC! Use common sense and all possible caution! I grabbed ahold of one of the […]
Justin says, “What do you get when you bring over 150 kids into a workshop and tell them they can build whatever they want? That is what we did at the Bakken Summer Science Camp and they came up with some amazing stuff. Boats, cars, robots, secret alarms, ping pong ball throwers, light up dog […]
Jonathan Filippi says, “It is a classic push-pull design, taking care to obtain best symmetry (to avoid flux walking). Keep in mind that this circuit will adsorb many amperes (around 10A) so take care to reinforce power tracks with lots of solder and use heavy wires from the battery or the voltage will drop too […]
It’s a widgetized touchscreen open source thingy that connects to the internet via wifi. Mad hacking to ensue. – Link
Pat says, “Using the same basic techniques as other PCB etching instructions, I have added a helpful twist – a BMP grid to help draw the design without having to use complex layout programs.” Link.
