OnChip has posted a Crowd Supply update on their plans for Arduino compatibility:
Arduino compatibility can mean a lot of things to a lot of different people, so we’ll try to be as concrete and specific as possible. For the Open-V, Arduino development tools, and interoperating on a hardware level with existing Arduino shields.
We’ve updated our live, web-streamed demos to include an Arduino mode in addition to the assembler and C modes we already have. You might also notice the relatively new Blockly modes and a refined layout of the demo page. Go write some code and see the results live streamed!
Bristlebots are great because no coding is required – they’re completely analog circuits that just go! But if you wanted them to go in a specific direction, how would you do that? Facelesstech has released their design for a light-following bristlebot that uses two LDRs to drive either side of the bristlebot (so you could turn it, somewhat – see video below for demo!). It’s pretty simple and pretty clever.
The KiCad design files are available on GitHub:

Neven Boyanov has launched a new Tinusaur campaign on IndieGoGo:
The Tinusaur is powered by the Atmel ATtiny85 microcontroller.
We want to bring the cost down to $3 for the basic “lite” boards
and allow more people to be able to get them.
Black Mesa Labs created this board that adds a Lattice FPGA to a Raspberry Pi:
BML has been very much enchanted with the Lattice FPGA boards for Raspberry Pi, IcoBoard , BlackIce and IceHat. The IceZero board is a BML creation that attempts to combine the best features of all 3 boards into a single design.
IceZero features common with other designs
- Fully Open-Source Hardware and Software Design.
- Lattice ICE40HX4K FPGA that supports Clifford Wolf’s Project IceStorm tool chain.
- Interfaces to Raspberry Pi 2×20 GPIO Header for both power and bus interfaces.
- PROM programmable directly from Rasp Pi, no JTAG programmer required.
- External SRAM, supporting soft CPU core designs ( code execution ).
- Extra large SPI PROM, supporting soft CPU core designs ( code storage ).
- Industry standard PMOD expansion headers
IceZero features that are BML specific
- Mesa Bus Protocol 32 MHz SPI link between CPU and FPGA.
- 2-Layer PCB design. Orderable via OSH-Park or Gerbers for Downloading.
- FTDI 1×6 USB Serial Cable header for use with PC instead of Pi ( or as a soft CPU debug Trace Port ).
- Single Pi UART plumbed to FPGA for muxing to multiple external serial devices.
BlackMesaLabs has shared the board on OSH Park:
