one motor walker v.2

this is my second version of one motor walker. it walks more faster than the previous one, it moves forward and backward with dpdt switch (hope to be able to use tactile sensor for the next project). the bot uses linkage at bottom to move the rear and front legs. find out more about my homemade robot projects on: kitchenlab-robot.blogspot.com

DIY DD-20 Delay tap tempo

All the parts were ordered from PedalPartsPlus.com. The switch is a DPDT Momentary Switch, while the input jack is a simple mono, and the enclosure is just the small one. It's all pretty easy to find. You can use about any wires that can carry a current. I used normal speaker wire from a home stereo. It's about $15 in total. After your iron heats up, you can have a tape tempo in a matter of minutes :)

Truck Horn.wmv

Video of my Stuttertone air horn finally finished on my 2007 Nissan Frontier Truck. The horn sounds a bit off due to the cold. I tied the horn into the stock horn pad with a switch to toggle back in forth between the stock and air horns. I used the power from the stock horn and routed it to a single pole, double throw switch. The air is via a hornblasters 2 gallon tank with a 150 psi air compressor.
