Rich Decibel’s Kequencer

It’s totally excellent when a simple concept results in something inspiring and fun. [Rich Decibel]‘s Kequencer is a good example, starting off as many projects do: “I had an idea the other day and I couldn’t decide if it was good or not so I just built it to find out.” Be still our hackable hearts!

[Rich] built this sleek little sequencer from scratch and while the design may not seem very novel to begin with–eight square wave oscillators with on/off switches and pitch knobs, played in sequence–but the beauty of it is in the nuances of interaction and the potential for further hacking. From watching the video you can see how the controls can be used in very interesting ways to create and mutate adorable chippy tone patterns. Check it out after the crossfade.

The Heinz Automato

[Bill Fienup] and [Barry Kudrowitz]‘s robots, The Automatos, have been leaving a sticky path of destruction all over the internet. Their sole purpose: to crap ketchup. They accomplish this feat by dumping a CO2 cartridge into a ketchup bottle at the push of a button, leading to some pretty awesome results.  While the details are a little sparse it appears that they are using RC cars for the base and a small air gun CO2 cartridge to push the ketchup. The latest version aka the Atuomato 4 appears to be multi-actuated and can shoot more than once for maximum ketchup proliferation. See some videos of it in action after the break.

Home built knitting machine

Wow, we knew it wouldn’t be too long before we would see a fully automated home built knitting machine show up. We recently posted a hack where people were emulating the keyboard input of a commercial knitting machine, and that was pretty awesome, but we knew we would be seeing some hacked together machines soon. [corex37] hasn’t let us down with this beast. It is mainly composed of old printer parts, a couple servos, and a Picaxe 18-x microcontroller. It seems to do a good job right now, but lets hope he keeps going. It would be cool to see it able to change colors like the other one.

SD activity indicator for Wii

[DeadlyFoez] wanted to know when the SD card in his Nintendo Wii was in use. He built and indicator LED using a PICAXE 08M and added it next to the SD slot. He uses one pin of the microcontroller to monitor the voltage on one pin of the SD card slot. That pin has a specific value when the card is idle, which rises when it’s in use. He didn’t share the details of which pin he’s sampling, or what the magic number from his source code actually represents. But the concept should be enough of a start if you want to do this one yourself. Watch it go blink-ity-blink in the clip after the break.
