This project uses the open-source i2c RGB LED controller firmware “cyz_rgb” to create a modular high-power lighting network. The network is controlled by an Arduino, which scans the network for nodes controls them autonomously with onboard scripts, manually via serial…

SlatePermutate
SlatePermutate is a PHP and Javascript-driven interface for college class scheduling. SP parses course identifiers (such as MATH-2500) and autofills all available sections associated with the course. After submission, SlatePermutate presents a tabbed interface of all possible schedules, course conflicts…
ZonCoffee Hardware
The Eagle schematic for ZonCoffee is included after the break. Note that this schematic still has a few quirks, but it should be accurate to the best of my knowledge. I will post the Eagle project once the design is…

ZonCoffee .2 Released
ZonCoffee is a full-featured PID controller package for Arduino, customized for use with espresso machines. ZonCoffee is written in Processing/Wiring, and includes some code from Tim Hirzel‘s BBCC project.
DIY CNC Progress
Since my last post, I have completed my junction box and I have prepared 3 motor/speed controller assemblies. I have acquired a second leadscrew to use for my Y-axis, and the electronic portion of the construction (except for limit switches)…
Initial DIY CNC Prototyping
I’ve started constructing the basic electronics for the CNC machine I’m working on. It’s going to be a cheap machine made with what I have on hand, so accuracy won’t be great, but it should be an interesting experience. The…
EC155 PID with Arduino
This is a build log of my PID modification to my DeLonghi EC155 espresso machine. Currently, the machine uses an Arduino to drive a solid-state relay controlling the heating coil. The Arduino displays mode and temperature on a serial lcd,…
The OSRAM SLG2016 and AVR
I happened to scavenge a couple of SLG2016’s from some old workstation debug displays. After finally locating a datasheet, I realized that they used the standard ASCII charset, so they are extremely easy to drive. Note: The SLG2016 differs from…
DIY High-Quality Block Printing
Ever wanted to cover your wall with a nice high-resolution DIY poster? With a little bit of effort and a lot of paper, you can make a high-quality block-printed poster with free, open-source software. This method produces a nice smooth…
Macro video and photos with the S3 IS
With a couple bucks worth of cheap macro filters, you can get great macro video and photos with the Canon S3 IS (works with the S1 or S5 IS as well). All you need is a lens adapter that fits…
