Last year i bought a cheap chinese prusa i3 clone for €270 including VAT and shipping which performs very good overall. After assembling it – which took me about 8 hours – its print results was.. well.. quite okay. As expected, because reading forums and blogs already explained Z wobble to be a serious problem […]

This summer I bought a prusa i3 clone from geeetech, a cheap chinese printer manufacturer. With 270€, including VAT and shipping, the DIY-kit is quite cheap and 8 hours later i had a prusa i3 clone that prints “quite okay”. [more here] This printer has a direct drive, bowdenless MK8-style extruder. While it prints really […]
As previously described, I made a simple adapter to mount a 405nm blue laser diode to expose PCBs. There are for sure other methods that seem simpler, like separating the laser toner from a print or printing on transparent film, but our goal was to make it a “just press start” method using things we […]
I am currently thinking about adding a laser to our Ultimaker 2 at work. Primary use case would be exposing PCBs to etch them on our own. For this task we need some UV laser on the printhead. Well the chinese sellers on aliexpress.com sell them for less than 2€ including P&P, why not use […]
This year I improved my christmas tree LED lights from last year (https://plus.google.com/106975890398198714969/posts/EaUEFXzoxED) I removed the Infineon MCU (XMC1100) which already was at it’s limits and replaced it with an ESP8266. So i put the cool and versatile WiFi enabled MCU under my xmas tree, featuring an ugly, crude web interface using ESP8266WebServer (i […]
Its holiday time and i thought it’s time to revive this old blog and update some stuff. Let’s see how far this intent will come ;)
Long time ago I coded tools to capture, demodulate, decode and decrypt data from an Software Defined Radio (SDR). As i dont see any reason to keep it private, i decided to release the source code. I mainly used a device that is comparable to the USRP, but designed by a friend of mine. Still […]
Since last year I helped a little developing Magic Lantern, a Firmware mod for Canon EOS DSLRs. I reverse engineered some interesting registers and memory structures that make frame rate patching possible. (yeah, as always I couldn’t resist reverse engineering the next device I bought :) ) Now I’ve coded a little tool that makes […]
I added Kraken-win32 to my projects page. There you can read more about my kraken port.
I added a new project – my WebDAVServer for mobile phones. It was designed to be a small and simple WebDAV server for downloading files from your PC with your mobile phone. See the project page.
