My Projects

I build a 1.6 W 450 nm laser cutter / engraver mostly from China parts.

Yet another laser engraver / cutter

A low cost Energy-Monitor system which is deeply influenced by the openenergymonitor.org projekt

Yet another energy monitor

I improved the mechanics on my first laser plotter to get a more accurate machine to make PCBs with it.

Yet another laser engraver / cutter 2

Here I describe my method for making 1 and 2 layer PCBs at home via lithography and etching

Yet another guide on how to make PCBs at home

Here I build a external GNSS module for mobile devices without or unsatisfactory navigation GNSS option.

GNSS bluetooth module with u-blox NEO8N

In this project I build a smaller version of my previous GNSS module. The main features are: LiPo battery, USB, active antenna, bluetooth
