Today I thought it would be a good idea to make A  sd-card reader as an extension for my Ultimaker, I designed it for the newer electronics which can use the SPI pins because there is a break out to an expansion header. Because I printed a prusa mendel on my Ultimaker a few weeks ago and I’m aiming to use Ultimaker electronics for it the new printer. Read the rest of this entry »

Taking time back

A week ago I found this simple quarts clock and thought about the idea of making the clock turn backwards, which would be pretty easy and cool. I found this clock without a clock-face in my garage and took it apart, but when I did reversed the 2 connections to the electromagnet it still turned the right way. So I started looking for an explanation and found Read the rest of this entry »

Last summer I did the development of the electronics v1.1 (and v1) of the Ultimaker 3D printer. I got this opportunity because I had some connections at Protospace, and was asked to become one of the pioneers of this new design and new 3d printer. Last year in April I made myself a promise that I wanted to have a 3d printer within a year and this worked out pretty well because of the opportunity Protospace gave me! 3D printers are just super cool and a total new way of making things (at home!). Make sure you check out this awesome 3D Printer: Read the rest of this entry »

It’s a bit stange but there are so much project I’m doing that I can’t get the time to post them online. I already wanted to post this for quite a long time so there it is…

A couple of months ago, in the summer I made a prototype with my cnc machine of a, sort of, centry gun turret. I milled them from a piece of plywood 4mm which is prefect for making little simplistic things like a turret. Since I already got this hand loaded airsoft toy gun I first made some drawings and milled them. Read the rest of this entry »

Since I made my little Atmega16 avr development board I wanted to make a program to read out a Wiimotion Plus which I bought from Dealextreme for about 12 bucks. The Wiimotion Plus works with the Two Wire Interface (TWI/I2C) and since I already got the protocol working with an EEPROM chip I needed to do some investigation on this WM+. This wasn’t a big problem since I do have a Bus Pirate which is a super awesome tool for interfacing new chips without writing code! So I did not have to worry about writing code, I only had to try and find the right commands to put on the I2C communication line. So I played with the Bus Pirate and the WM+ for some time and found out that its real easy to interface the WM+.

My little AVR development board

Posted: October 11, 2010 in Uncategorized

About a month or 2 ago I decided a build a little development board for an atMega16 avr chip, because I didn’t want to build a breadboard for every single application. So with a friend of mine we made the schematic and designed a  board with a lot of pinouts for the most common used applications including serial communication, two wire interface (TWI/I2C), analog digital conversion, i/o (switches and leds), and some timer/counter pins.

The schematic and board; Read the rest of this entry »

Here’s something I made lately, a real magic box 😉 But what is it, and why the giraffe?! Well the back of the case speaks for itself!
