robot projects

I searched my photo albums for some pictures of robot stuff that I did the last years (robots being only one of many interests).

How it all started (the robot uprise):

Project: Self balancing bot with manual PID

ugly prototype:

I’ll hopefully never do airwiring again – hint: invest the time layouting pcbs instead:

ABB robot retrofit:

Quick and dirty conversion (Marius is a genius) during the LinuxCNC meet 2015 – with some groundwork of mine (getting curcuit plans, “some” probing, …).

I stumbled upon this little guy somewhere on ebay Kleinanzeigen (~Craigslist) and could not not-buy it.
Me (electronics) and two friends (software) hacked it to a Raspberry Pi.

kallax style shelf

CAD files (and hopefully soon the Rhino script to optimize cutouts for milling)

Rendering (before milling):

I don’t really like the material Ikea’s Kallax are made of – also I consider buying at Ikea only as emergency solution.

Still we needed a shelf to store stuff and so I went to the local hardware store and bought 11 250x2500mm laminated
beech planks cut to length – not of the car (though it certenly seems that way).


Some milling (about 4 hours):

The result:

After some quick sanding of the corners and a some hours doing 2 coatings of linseed oil
we could piece it together in no time.


I even added drill holes for these pins (German: Bodenträger):

Screwed to the wall:

^^many projects waiting for completion.

Conclusion: Building furniture isn’t that hard if you have access to the right tools.
Also it’s not really that expensive.


  • 208,45€ 11 planks of 250x2500mm laminated beech planks (we still have enough for the loft bed)
  • 16,50€ 2l lineseed oil from Hornbach – at Obi it was like more than twice the price
