Submission + - What if your electronic parts were more like Legos? (electricdollarstore.com)

Submitted by beckman101
beckman101 writes: This week Electric Dollar Store opened its doors, selling interchangeable postage-stamp sized I2C-based modules for prices between $1.00 and $1.80. The modules include lights, buzzers, counters and sensors — the range is aimed at electronic makers. These aren't manufacturing rejects shipping from Asia — they're assembled, tested and shipped from a small farming town in California, where winter labor is cheap.
All the code for the project is BSD licensed.

The project is a spin-off from the popular open-source I2CDriver (https://i2cdriver.com/) hardware debugger.

Ask Slashdot: Automated Verification For Uploaded Files? 74

Posted by timothy from the sniff-test-sanity-check dept.
VernonNemitz writes: There are a lot of ways for hackers to abuse a web site, but it seems to me that one of them is receiving less attention than it deserves. This is the simple uploading of a malware file, that has an innocent file-name extension. I'm looking for a simple file-type verification program that the site could automatically run, on each uploaded file, to test it to see if it is actually the type of file that its file-name extension claims it is. That way, if it ever gets double-clicked, we can be assured it won't hijack the system or worse. At the moment I'm only interested in testing .png files, but I'm sure plenty of web site operators would want to be able to test other file types. A quick Googling indicates the existence of a validator project under the OWASP umbrella, but is it the best choice, and what other choices are there?

Submission + - Project IceStorm passes another milestone: building a CPU (excamera.com) 2

beckman101 writes: FPGAs — specialized, high speed chips with large arrays of configurable logic — are usually highly proprietary. Anyone who has used one is familiar with the buggy and node-locked accompanying tools that FPGA manufacturers provide.
Project IceStorm http://www.clifford.at/icestor... aims to change that by reverse-engineering some Lattice FPGAs to produce an open-source toolchain, and today it passed a milestone. The J1 open-source CPU is building under IceStorm, and running on real hardware. The result is a fairly puny microcontroller, but possibly the world's most open one.

Submission + - Arduino Gaming: Not So Retro Any More (kickstarter.com)

Submitted by beckman101
beckman101 writes: Two years ago the Gameduino brought retro-style gaming to the Arduino. This week its successor launched on Kickstarter, still fully open-source but with a video that shows it running some contemporary-looking demos, plus it has a touch screen and a pretty decent 3-axis accelerometer. Farewell to the retro?

Submission + - Gameduino: "Ridiculously Awesome" (createdigitalmotion.com) 1

But what makes this project special is that this inexpensive board has hardware that'(TM)s capable enough to be interesting. The result is a lo-fi game console built on an FPGA that gives you retro graphics without being, you know, too retro. Games actually look good."
