Solderless Drawdio Terminally Implemented

So you’re stuck in a boring class and you can’t fight off the urge to hack something, even your pencil, to pass the time. Maybe you are performing a live electronics show and you drop your synth down a flight of stairs and all that you are left with is a handful of components, a screw terminal block and a pencil. There are thousands, perhaps millions of these kinds of situations and for each one the answer is the solderless drawdio clone by [Martin].

You may have seen the original Drawdio here before, a fun piece of technology that is simple enough to recreate. This latest approach would make an excellent introductory project for a hacking workshop seeing as the guide is straightforward and the lack of soldering would make logistics so much easier. The results are very similar to the original–check the video after the break. [Read more...]

Czech Discovery Ressurects PS/2 Keyboard

Like us, you probably have piles of old PS/2 keyboards occupying strategic positions in your house and causing all sorts of trouble with the neighbours. As luck would have it, there is a way to put those lazy peripherals to work!

Our friends in the Czech Republic have successfully interfaced a PS/2 keyboard to an STM32 Discovery board (translated), and not a moment too soon—just in time for you to integrate their work into your entries for those juicy contests we told you about (the European one and the North American one).

The project page contains an in-depth walkthrough of how the PS/2 connection talks to the keyboard hardware along with source code and links, more than enough information to get started with a PS/2 keyboard hack on your Discovery application. And why stop at keyboards? Give your old PS/2 mouse a new lease on life, or even hook up your custom game controller to spice up the experience.
