Unlike microcontroller projects, projects involving FPGAs cannot yet claim to rely on a mature open-source toolchain. Each FPGA will, at some point, need to be configured with a proprietary bitstream produced from a closed source synthesis tool. This lack…

already been thinking of a project where I might want to use a cheap FPGA with open tools...

The Folio Society is doing a gorgeous new edition of Frank Herbert's Dune, and we were excited to show you the front cover a while back. But just wait until you get a load of the interior art, also created by artist extraordinaire Sam Weber. [Warning: One picture might be NSFW.]

OpenEmbed launched a 52 x 28mm "SOM9331" COM for IoT that runs OpenWRT Linux on a MIPS-based Atheros AR9331 SoC, and offers WiFi and extended temperatures.

An Enigma watch, hand built everthing around an Arduino. That is cool.
Deffo one for you DaveAnders...
A three rotor Enigma machine wrist watch. March 24th, 2015. IMG_3636. This is one of the most satisfying projects I have done I think. Mainly because this is a real device and something so historically important. It is a fully functioning Enigma machine you can wear on your wrist.

If we burn a USB Mass-Storage and smoke comes out of it, I wonder if all the Data goes to the Cloud ?

A nice presentation on target-side USB for Linux (aka USB "gadget") that I would have mentioned during my own embedded USB talk as a reference for further info, if only I had run across it earlier

+Philip Balister - seen this?
Ref. Price: US$169~230. Features. l USB based modulator/demodulator with support for EN 300-744 DVB-T transmission and reception. l Powered from the USB bus, so no external power adapter is required. l Full hardware modulation/demodulation, no host CPU computation required.

Continuing with our question series (question 3 now), we've had some discussion of the serial debug port on the board.

On the original MinnowBoard we used a USB mini b port (that had an UART to USB translator chip on the board)

On the MinnowBoard MAX we opted for a 6-pin TTL (3.3v) header.

Which do you prefer

Although the final solution is the same using a TTL-USB converter, the choice of the 3.3v present the board as if it lacks something.

Thanks to +John Hawley​ and +Intel​ for the sweet Tadpole Proto Board for +MinnowBoard​ MAX!
It has an RGB LED, too.

Embedded Linux Developer
Introduction

I am an embedded systems engineer specializing in the integration of hardware and software at the lowest levels utilizing Open Source tools, bootloaders, and operating systems such as Linux to rapidly produce quality products. Past product developments have included the TCSX-1 thin client for Advantage Business Computer Systems, the M5900 handheld for American Microsystems Ltd., and the PandaBoard for Texas Instruments.

My specialty is complex problem solving to provide rapid solutions to both hardware and software issues. This includes reverse engineering existing legacy projects as well as processing, assimilating and filtering large amounts of datasheets, schematics, software source code, and management specifications.
