While developing the Luma RS485-networked LED driver we discovered a need for a small and inexpensive USB to RS485 adapter. We designed an adapter with a FTDI basic UART chip (FT230XS) and an inexpensive TI differential receiver (SN75176). Our small…

BeagleBone Black and DTC
Arch Linux ARM currently includes an unpatched version of dtc (device tree compiler) which lacks the “@” option. If you want to enable additional UARTs, SPI, I2C, or just use GPIO without recompiling the bootloader, you need a patched version…
Open Hardware Pogo-Pin Programmer
The ProtoProg is a small open source hardware pogo pin programming solution. The ProtoProg 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…

PicoBuck RGB LED Driver
The PicoBuck is a small and inexpensive 3-channel LED driver. It employs constant-current buck driving which approaches an efficiency of 95% (theoretical). Now available from SparkFun Electronics!
Luma Node Development
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…
TriFet Motor Driver
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…

Maker Faire Detroit ’12
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.
MNL Updates
Luma Node 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…
A2 Mini Maker Faire
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…
