External pinball controls for an Android tablet

android-pinball-controls

This hack, which adds external flipper controls to Android pinball, is a great way to cut your teeth at Android hardware hacking.

[Ruben] decided to go with the TI Launchpad for this project. The MSP430 dev board offers serial communications via a USB connection, but it’s not quite as easy as just finding the right cable. His tablet does … Read the rest

Weather-O-Matic displays digital weather on an analog face

SANYO DIGITAL CAMERA

This clean-looking readout uses analog dials to display the weather. [Nuno Martins] calls it the Weather-O-Matic and after the jump he explains what went into the project.

The hardware is about as simple as it gets. Each hand has a servo motor attached to it. An MSP430 gets the weather via a serial connection to a computer (data is … Read the rest

MSP430 touchscreen piano

msp430-touchscreen-piano

[Rohit Gupta] wrote in to share this touchscreen piano project he built around the TI Launchpad. It provided a way for him to explore using a resistive digitizer found on a lot of mobile devices. These are simply stuck to the top of LCD screens and replacements are inexpensive, but salvaging one from old hardware is an option as well.… Read the rest

Chromebook hack controls your television

chromebook_remote_control1

[Michael Kohn] only accomplished about half of what he set out to, but we still think his TV channel switcher from a Chromebook turned out nicely. When starting the project he wanted to include a grid of listing so that he could choose a specific program, but decided that scraping the data was too much work for this go-round.… Read the rest

Automatic Closet Lightswitch

[Dillon] wrote in to tell us about his latest project, an automatic light switch for a the hallway closet in his house. Although this project could probably be done very simply, [Dillon] accomplished everything in a way that actually looks professionally done and has some neat features. Check out his site for more pictures of the build.

Not that … Read the rest

Making it Easier to Build Firmware

OSHW Logo

Most microcontroller manufacturers give you some kind of free development toolchain or IDE with their silicon products. Often it’s crippled, closed source, and a large download. This is pretty inconvenient when you want to have firmware that’s easy to build and distribute. I’ve found many of these toolchains to be annoying to use, and requiring closed source software to build … Read the rest

Lord Vetinari’s clock strikes again

vetinari

Inspired by the maddening timepiece from Discworld, this clock keeps time, but anyone watching the seconds tick by may be mentally unstable for it. [Renaud Schleck] built the stuttering clock using very few components. He undertook the build after being inspired by the version which [Simon Inns] built.

The clock itself is a run-of-the-mill item which uses … Read the rest
