Circle of lights

I’ve soldered together a chain of Adafruit NeoPixels to create a circle.

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.

3D Printer Part 4: Adapting Y-axis

DSC_0464 (Custom)

I had some time last Sunday to start adapting the Y-axis on the 3D printer project.

3D Printer Part 3: Attaching stepper motors

3D Printer so far. Can't print anything yet!

3D Printer so far. Can’t print anything yet!

In this post I attempt to describe how I attach the stepper motors on the X and Y axis, and how I’ve started mounting the lead screw for the X-axis.

3D Printer Part 2: The starting point


Building a 3D Printer from a microscope – Part 1

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 at mechanics and xyz control.

Some things to come…

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!

IR Transmitter and Receiver

IR Transmitter / 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

mask (5)

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.

A big change

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!

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.

RC Servo Motor Control

Here I will present a servo control code I wrote for the BrontoBot to run on most AtMega AVRs. Read the rest of this entry »

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.

This post describes the making of a USB programmable microcontroller board using the atmega16u4 microcontroller. This is the board I’m currently using to control the BrontoBot.

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 good old fashioned glue.

Later posts will describe the making of the pcb, programming the movements and further upgrades.

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.

Nintendo 64 controller on AVR

I went on my regular trip to the dumpster the other day, and found no less than two Nintendo 64 controllers. It’s time to connect them to a microcontroller!
