This tube amplifier is constructed uses point-to-point connections and the majority of the parts have been salvaged from old electronics. The amplifier uses 6T9 compactron vacuum tubes in a push-pull output stage.

I have done a simple infrared remote control receiver with RS232 ascii output. It can be used for developing remote controls on a PC using the serial port.

This Instructables details the construction of a PICAXE-based digital oscilloscope designed to meet most hobbyist’s needs and which can be built for under $100 (the author spent about $70 on his).

If you have an Arduino project where the dev board is stuck inside a machine, or attached to the rafters or is inaccessible in some other way, a wireless programming/debugging link will save you tons of time.

If you have a 3. 3V FTDI cable, turning it into a Propeller programming cable is rather easy. A modified cable is cheaper than a propplug, too!

This 12-keys keypad failed after years of daily use. No schematic or replacement parts from the original manufacturer. The only option was to replace it with an off-the-shelf telephone-style keyboard.

Have you ever touched those gummy buttons on an old Sony Betacam recorder? Ever admired this warm glow beneath the play-button? Ever wanted to add some of these to your own do-it-yourself projects, only to find you can’t buy them nowhere? well here’s a cheap and easy way I found to make them on my own… [via] [photo]

Using some gyros and sensors and the Arduino for a brain, this group of roboticists created their own segway-like balancing robot. The project details are listed below and you can read the entire build process.

For anyone interested in making they’re own laser rangefinder I’ve stripped down the original schematic to make it easier to understand and to adapt to your own robot.
