20m Dipole

Written by Tim on 2018-05-28 20:53 UTC

I made a very simple 20m dipole. It's two lengths of wire connected to an SO-239 connector in a PVC enclosure, and tied off to the swamp cooler on top of my roof and a nearby tree.

This part covers the programming and lighting modes. Source code is down at the bottom for download, as well as on github.


Stepmania Controller

Written by Tim on 2013-05-25 23:50 UTC

This was a simple arcade controller I made with the laser cutter, an Atmega 32u4 board, and some arcade buttons. Another simple project. It worked pretty well for quite some time, but I just plugged it into my Windows 10 computer and I got a lovely BSOD, so I might want to revisit this one in the near future. Maybe give it the IIDX treatment.


LED Cube

Written by Tim on 2011-11-01 18:54 UTC

This is an LED cube I made from a minimalist arduino, some resistors, and a bunch of LEDs back in 2011. Not much to it really, and a couple of the LEDs are out at the moment. Not sure why. *shrug*


Zombie Laser Tag

Written by Tim on 2010-11-05 13:13 UTC

This game was made as part of an internet video series back in late 2010. It was called the 'Take on the Machine Challenge' and pitted 5 hackerspaces against each other, to make a cool project given a donation. Unfortunately the video documentary of our work has since been taken down, and we don't have a ton of records from this time.


Animatronic R2-D2

Written by Tim on 2010-04-02 22:00 UTC

This is a project from the old Transistor days. It never got a blog post, but it should have, so now it will. My Friend Wharff had an R2-D2 USB hub that made a long series of beeps when a button was pressed. He wanted to learn about electronics, and asked for my help in making the top of R2's head to move about with blinking LEDs when the button was pressed, in addition to the sound it makes.
