Your computer might be loaded with USB drives, external HDDs, and more, but can it control an LED lamp or a robot face?

Computer Controlled LED Lamp

The “headLamp” consists of “about 300 leds soldered into a metal colander (like you use for straining noodles)” and are “wired to a circuit and controlled by the [computer’s] parallel port”.

The iTunes plugin is written to accept sample data from iTunes when a song is playing, which takes the form of an integer between 0 and 128. The plugin operates under the assumption that a rhythmic beat is likely to send a higher value, around 120. If a sample value over 120 is sent, the plugin changes the lamp’s state based on preprogramed patterns like rotations, buildups, etc.


Robot Face

Put simply, this computer-controlled robot face is one of the coolest projects we’ve ever seen.

The iRX board is a small kit that provides everything needed to use a PIC microprocessor. It includes an RS-232 serial port, an oscillator needed to run the PIC, a status LED, IR LED and receptor, and a voltage regulator so that any standard 9V battery (or equivalent power supply) can be used to power the PIC. The iRX board also has a small prototyping area for additional circuitry if desired. For this project, the iRX board ended up being exactly want we needed to connect the computer to the head

Paintball Gun

Created by “Bogeycade007”, this impressive “tank”-inspired, computer-controlled paintball gun is capable of firing multiple rounds in rapid succession .

Wireless controlled tank paintball gun. All electronics were made from scratch except the wireless receiver and transmitter

R/C Car

Nasa Tjan and Ellias Ismail partnered to create this software-driven remote controlled car, “during the final year of his [Nasa Tjan] computer science degree at the Malaysia Campus of the University of Nottingham”.

Airsoft Gun

A reader sent in this ” demo of a fully computer controlled airsoft gun shooting down targets” — it’s quite interesting to say the least.
