This weeks project is a simple 4-step sequencer based around a 4017 decade counter chip. The basic schematic is based on this circuit, using a 555 timer as a clock source:
I changed it a bit by having the 4017 outputs drive transistors that switch current to the pitch pots (instead of turning on LEDS). [...]
Next in line for my ongoing ‘One Instrument a Week’ project is an Atari Punk Console with a few mods to make it more interesting.
The basic schematics for the APC are pretty simple:
The entire thing is built around a cheap 556 dual timer IC. GetLoFi sells a kit, but I chose to get the [...]
I’m starting a new project that will hopefully get me motivated to make some tracks. It’s called ‘One Instrument a Week’, and it’s exactly what it sounds like. I’ll be building one simple music instrument or effect a week for the next year, and using them in my experimental Year of the Duck [...]
I just got my DFRobot 4WD Arduino Mobile Platform from RobotShop (Arduino not included).
The whole kit was pretty simple to put together, and DFRobot throws in a couple of nice extras like a toggle switch for power, and a female receptacle you can use for your charging system. All in all, it seems like [...]
The Arduino Mousecatcher is a quick project I put together to learn some of the basics of working with Arduino, and to assist in the relocation of a little gray rodent I’ve seen darting around the baseboard in my bedroom.
It was built only with an Arduino, a servo, and miscellaneous things I had laying around. [...]
An Arduino powered sound synthesis / effects box.
Mobile Arduino / Netbook powered telepresence, featuring webcam and IR rangefinding.
