The “Cantenna Radar” is a radar project that we (Tony Hyun Kim, Nevada Sanchez, Paresh Malalur) assembled from a kit provided by Lincoln Labs for an IAP 2011 course at MIT. The name “Cantenna” derives from the fact that the antenna actuators are actually recycled coffee cans! Photographs and basic schematic of the device are shown below:

This is a super-accurate clock that uses ping-pong balls as diffusers for LEDs, but with a little know-how you can turn this into a full marquee display. [via]

A simple development board seems like a fun project. I’m recording my ideas here, and hope to get some input from other members of the ‘uC (or anyone else).
To avoid feature creep, I think several levels of dev-board would be a good idea. This page will describe my ideas for a level one board, I will add pages for additional boards as ideas arise.

Programming microcontrollers isn’t hard. Building a programmer makes a great first electronics project. The goal of this instructable is to explain the simple ‘in circuit serial programming’ method used with Microchip PICs.

For the past two years, I’ve been planning to build myself a 3D printer from some old Inkjet printers I had collected over the years. But not until two weeks ago had I actually started to work on it.
The 3D printer I want to made uses a ink jets to print a chemical onto a building platform. The building platform has a goes down as a new layer of power is spread onto it and the chemical sprayed from the print head will cause powder to bind.

I always was thinking of a measuring tape that never ends and be able to measure very long things. So I decided to make a small odometer and use it as a digital measuring tape. I used a PIC16F819 microcontroller and a sensor from an old computer mouse (the remaining parts of one of my other projects Crazy Mouse) to make this simple measuring tape. Do you want to make yourself? If yes read the rest of this instructable.
