In order to interact with an FPGA board, a user usually presses a button. Is that the only way to interact? Not so sure. A video from Clifford Wolf shows us otherwise. It’s quite intriguing! The Verilog implements a simple ring oscillator (basically an inverter with its output tied to its input).

Litecoin Mining With FPGA – This Is Cool

Is anyone keeping up with the newer Bitcoin successor, Litecoin?

We wanted to provide some information for you about the newest peer-to-peer cryptocurrency and open source software project released under the MIT/X11 license. Yes, it’s completely open-source, and you can mine these little guys on your FPGA platform.

Educate yourself a “bit” before we go on:

I’m thinking I want to ask Jack how much work it would be to implement this on Papilio, but if any of you guys and gals have already accomplished this, or want to hack it in, and post to the GF forums, it would help to extend all of our savvy!

Pi Store App Market Launches For Raspbrry Pi

For anyone who didn’t already know, Raspberry Pi recently launched their own app store called the Pi Store.  The Pi Store runs as an X application under Raspbian, and allows users to download applications for the Raspberry Pi, as well as to upload their own content which can then be approved for release on the Pi Store.

App developers can distribute content for free or for a price, and coders can submit binaries, raw Python code, images, audio or video, and soon Scratch content as well. The store is a community-driven portal that anyone can contribute to, and we should be seeing lots of innovative apps coming out for the Raspberry Pi.

You can find the new Pi Store at Raspberry Pi’s download page.

8 channel USB Digital Signal Injector

Here is an interesting project we found over at the project is called Kidogo, it is an 8 channel USB Digital Signal Injector. Definitely worth a look:

“Kidogo system consists with Signal Editor and USB interface module. Kidogo Player is the Signal Editor of the Kidogo system and it can support up to 512 time slots (each range between 1ms to 1s) with 8 channels.”

The Kidogo Player is designed for Microsoft Windows OS and it has many features, we can list some of them here:


  • Save waveforms and settings as binary file or export waveform as a text file
  • Playback controls such as “Play to segment”, “Play from segment”, “Step back”, “Step next” and “Clear”
  • Shifting and rotating waveforms
  • Invert, Reset, Clocking and Binary Generator functions
  • Mute function to each individual channel
  • Launch without any installation or configuration


Kidogo is an open hardware project and the original article is complete with full source code and PCB designs.

Feel free to discuss this project in the comments thread.
