The screen shot below says it all. Yay! Video output from the CPC2.0! I promised myself that I wouldn’t post those shaky photos/videos that people seem to post of their game/emulator/screen. Unfortunately, at this time a photo of the screen is the best I can do. Longer term, I’ll get a HDMI capture card from eBay […]

E-ink displays are awesome. Humans spent centuries reading non-backlit devices, and frankly it’s a lot easier on the eyes. But have you looked into driving one of these critters yourself? It’s a nightmare. So chapeau! to [Julien] for his FPGA-based implementation that not only uses our favorite open-source FPGA toolchain, and serves as an open reference implementation for anyone else who’s interested.
Watch the E-Ink controller in action:

Jim Kleiner created a minimal FPGA cape for the BeagleBone Black: BBB LX9 FPGA Board Jim describes his design decisions: I decided to try a minimalist hand solderable FPGA board. The LX9 is the largest part available in a TQG-144, beyond that its BGAs One of the key points is that the SPI interface is on BBB […]

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.

From the Hackaday blog:
Building a software defined radio (SDR) involves many trades offs. But one of the most fundamental is should you use an FPGA or a CPU to do the processing. Of course, if you are piping data to a PC, the answer is probably a CPU. But if you are doing the whole system, it is a vexing choice.
The FPGA can handle lots of data all at one time but is somewhat more difficult to develop and modify. CPUs using software are flexible–especially for coding user interfaces, networking connections, and the like) but don’t always have enough horsepower to cope with signal processing tasks (and, yes, it depends on the CPU).
[Eric Brombaugh] sidestepped that trade off. He used a board with both an ARM processor and an ICE FPGA at the heart of his SDR design. He uses three custom boards: one is the CPU/FPGA board, another is a 10-bit converter that can sample at 40 MSPS (sufficient to decode to 20 MHz), and an I2S DAC to produce audio. Each board has its own page linked from the main project.Z

Machinekit is a platform for machine control applications. It is based on LinuxCNC and can drive mills, lathes, 3D printers, laser cutters and more.
Machinekit can run on an Altera SoC which combines a hard silicon ARM core with a FPGA. Charles Steinkuehler has been working with the DE0-Nano development board from Terasic. MachineKit runs on the ARM core with the FPGA configured as a MesaNet card:
Charles designed a DB25 connected interface board, with pin-outs matching the P2 and P3 headers on a 5i25

Need additional, custom IO for your Raspberry Pi? Adding an FPGA is a logical way to expand your IO, and allow for high speed digital interfaces. [Eric Brombaugh]’s Icehat adds a Lattice iCE5LP4K-SG48 FPGA in a package that fits neatly on top of the Raspberry Pi Zero. It also provides a few LEDs and Digilent compatible PMOD connectors […]
Eric Brombaugh designed this board which pairs ARM Cortex M4 processor with a Lattice FPGA:
USB, Micro SD, PMOD and GPIO interfaces allow development of complex projects in control and signal processing.
