Circle of lights

I wanted my own LED strip that I could shape however I wanted, so I had to create my own. It would have been a lot easier to just purchase the ready-made light strip, but this one can be altered for the LEDs to point in any direction and stay that way.

Playing with a color sensor

I’ve spent a day playing with the¬†TCS3200 color sensor from TAOS (now ams AG). I’ve connected it to an Arduino and sent the color over the serial port to an application written in Processing. The application outputs the color found by drawing a square.

Building a 3D Printer from a microscope – Part 1

Simple extruder

I’ve jumped on the 3D printer wave, intending to build my own RepRap inspired 3D printer. I’ve found an old microscope platform to customize. This platform has an XY-table and a precise Z axis. I wanted to spend time building my own 3d printer, but not all of my time. I wanted to get better …

IR Transmitter and Receiver

This is an IR transmitter / receiver circuit I’ve made to control my TV, amplifier etc from my computer. It was made using a cheap Arduino clone, an IR module and an IR LED. The receiver can read most infrared remote controllers, independent of which protocol they may use.

The Mask

I’ve built an animated mask. It can move its eyes back and forth, and open and close its mouth. Everything is stuck together using duct tape and steel wire. It is controlled by an app on an Android phone, through a cheap Bluetooth module.

Beeping Motion Detector

We have this big box of candy at my office at work, that keeps getting more popular with people from the other offices. I wanted to make their sneaky candy stealing more detectable, with a beeping motion detector circuit.

Servo tester by 555 timer

I needed a servo tester for my workshop, to have at hand whenever I change servo horns or need to see if a servo is dead. I decided to use a 555 timer to do this.

Building the BrontoBot

I’ve started building a four legged walking robot, imitating the movements of a turtle. I named it the TortoBot (Tortoise Bot), but as it developed it started to look more like a dinosaur baby. Now, I call it the BrontoBot. This post describes the building of the robot body, using 9g servos, melting plastics and …

Using LDO as an adjustable voltage supply

I came across this Low DropOut voltage chip and figured I would use it as an adjustable voltage source. All it required was a trimpot, a capacitor and a resistor.

Electronic Sheep

The electronic sheep is a plastic sheep fitted with a rgb-led inside. It can show colors in various patterns, and the electronics also supports adding a servo motor for moving the head. I will describe the works and making of the electronics and code. This is a good beginners project for using an Atmel microcontroller.
