Fresh hacks every day
[Renaud Schleck] somehow got lucky enough to find a GPS wristwatch in the trash. It had a broken LCD screen so its wouldn’t be of much use on that next hiking trip, but he knew it still had potential. He used the GPS module and a few other parts to build this reverse geocache box.
Reverse geocache is a … Read the rest
EMC2 CNC keyboard labels
If you’ve got a dedicated computer running EMC2 for CNC control you may be interested in these keyboard labels. [Rich] mentions that they use the labels for their engraver at the Connecticut Hackerspace. Just print them out and glue them in the face of the keys.
Dev board seminars and freebies

After getting his hands on the Philips Hue smart lightbulb [Brandon Evans] cracked open some of the hardware to see what is inside. He also spent time working out the software tricks necessary to use Siri to control light bulbs from iOS.
If you haven’t heard of the Hue product before it’s an LED bulb that fits in a … Read the rest
The STM32 F3 and F4 Discovery boards have been around for a while now. We’ve looked at both separately and they’re impressive dev boards for the price. Now can get a closer look at each from this in-depth comparison of the two Cortex-M4 development tools.
To start off, both of the boards have the same size and footprint (there … Read the rest
eBay isn’t only about counterfeit designer handbags and boxes of all-marshmallow Lucky Charms, sometimes there’s actually something useful for sale. [Matt] found a bunch of Chinese-made ARM development boards with integrated LCD displays on the ‘bay, but without a reliable toolchain, these boards – as cool as they are – are nearly useless. Thankfully, he figured out how to do … Read the rest
Here’s a technique that will let you use the .NET framework on an STM32 Discovery board. [Singular Engineer] was happy to learn that the .NET Micro Framework had been ported for STM32 chips. It’s doesn’t look like the port has hit a stable version yet, but these instructions will be enough to get you up and running. This lets … Read the rest
[Gpuhackr] chose his username to explain exactly how he spends his time. For instance, here he’s using an STM32 Discovery board to drive an AMD Radeon HD 2400 graphics card. The ARM microcontroller isn’t actually using the PCIe interface on the card. Instead, [Gpuhackr] has patched into the debugging interface built into the card itself. This isn’t quite as straight … Read the rest
