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.
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.
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 …
I’m closing in on completing my biggest project so far, hoping to make a series of posts about it by the end of June. I will spare the details for later. Meanwhile I’ll also be changing jobs, going to start working for DataRespons now. Exciting!
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.
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.
So, now the website is powered by WordPress, and this should make posting my projects a whole lot easier! Plus I hope this makes it more readable, as it is no longer white text on black 🙂 I also get some nice new features and categories and such, neat!
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.
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 …
This entry describes a quick and dirty way of displaying accelerometer data on an android device. The application outputs the applied force as a circle, where the radius of the circle represents the magnitude of the force vector, with the gravity subtracted. It also demonstrates the difference between a shifting buffer and a ring buffer.
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.
