The PicoBuck is a constant-current buck LED driver capable of driving an RGB LED at up to 0.6A. This driver is designed for low cost, small size, and high performance.
The PogoProg is a small open source hardware pogo pin programming solution. The PogoProg does not need a physical connector on the board, it uses surface-mount pads for signals and thru-holes for alignment. Two standard footprints are available, the smallest of which takes up very little space–only 7.6mm x 1.2mm!
The PicoBuck is a small and inexpensive 3-channel LED driver. It employs constant-current buck driving which approaches an efficiency of 95% (theoretical).
Development has started on the next version of the Luma RS485 high-power RGB LED driver node. The new Luma node will include a constant-current buck LED driver, PCB-mount LED, temperature sensor, 16MHz crystal, and many other new hardware features–all in the same footprint. On the software side, we plan on adding DMX support in addition to extra LED fade routines and improved PWM resolution. Check back in the coming months for more updates!
The TriFet is a 3-nMOS one direction motor driver rated for up to 60A of continuous current. This motor driver is perfect driving high-current solenoids, motors, small electric vehicles, and other high current switching applications. I have released this design as open-source hardware, feel free to modify and fabricate it yourself!

Check out the ProtoFusion booth at the Detroit Maker Faire on July 28-29 at The Henry Ford in Dearborn, MI! We’ll be showing off our Luma music-synchronized lighting nodes and our inexpensive PID system for espresso machines.
Revision 3 Luma high-power RGB controller boards just got back from the fab, and we’ve populated and tested the first of the boards. The new boards include a 3-pin fan connector (power, ground, and tach) as well as improved thermal dissipation and support for both thru-hole and surface mount current-limiting resistors. The board is also slightly larger with mounting holes on each corner, a significant improvement from our old 3-hole mounting design.

We had a great time at the Ann Arbor Mini Maker Faire this weekend exhibiting our music-synced networked lighting system (with some pretty awesome last-minute paper cone diffusers). Want to learn more about the project? Check out our latest project posts.
If you want to see more Protofusion projects, including the MNL lighting system, check out our booth at the Detroit Maker Faire later this summer. For more information about the Detroit Maker Faire, check out the event website.
The new official deployment of SlatePermutate is now live on slatepermutate.org! Course data is available for the following institutions, with more to come soon:

I recently purchased a used Gaggia Classic machine on Amazon. After realizing that it was not as “lightly used” as the seller denoted, I took apart the entire machine to clean it up. I’ve written this guide as a teardown guide, but feel free to read it from bottom-up to get a clear understanding of how to assemble this machine. Feel free to drop a comment if you have any questions or information to add.
