1. Using pcb2gcode with Marlin/grbl firmwares

    Wed 14 August 2013

    Recently, I wrote about building a small CNC machine. I started to modify pcb2gcode, so that it is usable with Marlin/grbl type of CNC controllers (which, admittedly, support only a basic subset of proper G-code commands).

    Mainly, my issues were:

    • Marlin did not support imperial units.
    • Marlin did not ...
  2. Homemade desktop CNC router

    Homemade desktop CNC router

    During the last few months I have slowly been building a desktop CNC router. It is loosely based on Pleasant Mill by Zaggo, which in turn is loosely based on famous Mantis mill.

    I changed some parts of Zaggo's design to my liking:

    • I wanted an enclosed work area ...
  3. CarPC build part 2: hardware, still

    Sun 02 June 2013

    This is the second part of building a RaspberryPi powered CarPC. I ended previous entry with seemingly nice photos of home etched PCB of hardware revision 1. Unfortunately, things did not go as planned, and I had to derail this project a bit.

    After careful inspection of rev 1 PCB ...

  4. Scanning laser projector

    Wed 15 May 2013

    Preface (or, Why?)

    In the meantime while I gather enough courage/dedication to finish the projects I have started (e.g. master's degree, carpc build), I wanted to share what else I have been working on.

    It all started with an idea about SLS 3d printer, using light-curing resin ...

  5. Compiling code for Stellaris Launchpad with TivaWare

    Sun 14 April 2013

    So, half a year has passed by since I received Stellaris Launchpad kits from Texas Instruments. I just could not resist the temptation to get two of them for $5 each and I might just have found an application for them. Okay, let's write some code.

    Wait, I have ...

  6. Meta-post

    Wed 02 January 2013

    This is a post which briefly describes why I have moved on from Drupal to managing my static file with the help of pelican.

    • Since I'm writing so rarely, it didn't make sense for me to often go through the pain of upgrading Drupal and all it's ...
  7. CarPC build part 1: hardware

    Sat 29 December 2012

    This is the first part of building a RaspberryPi powered carpc.

    Over a course of few months (been busy with, eh, life) I've designed the first iteration of custom Atmega-based circuit which lets me interface with car's electronics.

    The main part of schematics (pdf)

  8. RaspberryPi powered car-pc

    Fri 28 December 2012


    Some time ago, I got myself a Raspberry Pi. Initially it was supposed to replace my home-theater PC but I found it's too slow. So, I had a problem- what to do with such a nitty device of Pi.

    This was not the only problem I had- my ...
