Fresh hacks every day
[Ytai Ben-Tsvi] wanted a rapid prototyping tool that could be easily and cheaply built at home. He came up with the PICMAN, a breadboard compatible PIC based board that has everything you need to get the ball rolling. He’s using a PIC18LF4553 which has built-in USB support that can be used with a bootloader for programming. The board also … Read the rest
If you’re like us you’ve got quite a few prototyping tools that are bare PCB boards. If you’re using them a lot you might want to protect them with some type of case but the lack of mounting holes can make this difficult. One popular solution to this problem is to design a case for a perfect fit, then cut … Read the rest
This project explores the early days of television. Above you see a view from the back side of a mechanically scanning television. The black disk spins and the holes, aligned in a spiral pattern, create vertical scan lines for projected light to shine through. In this case, [Eckhard Etzold] is using red, green, and blue LEDs to create a … Read the rest
We like to check in from time to time on the scratch-built tube amp scene. [Rogers Gomez] recently posted his build of a headphone tube amp. This is somewhat related to his work from 2008, but this time around it’s simple enough to serve as an entry into amplifier construction for beginners. The PCB layout is clean and … Read the rest
If you’ve had the opportunity to attend the annual Bay Area Maker Faire, you’ve likely encountered Russell the Electric Giraffe. Modeled after a small Tamiya walking toy scaled up to the height of an actual giraffe, Russell was created by [Lindsay Lawlor] in 2005 originally as an “art car” providing a better vantage point from which to enjoy the … Read the rest
