Game figures - Fairytales collection

An old copy of the board-game "Sagaland" has lost its figures over the time and will be a wonderful present with these replacements:

Wooden Jewel Case for CDs

Three plywood layers and a leather-binding. To be enhanced with a small magnet to keep the case well shut while it's closed ...

Acryllic Milkymist One Case

since lasering an early prototype in plywood for the Milkymist One interactive VJ Station i've been busy:

adding labels, modifying the mechanical concept and sourcing some really nice looking acrylic materials, as well as some metal spacers.

i just finished the first complete acryllic one and it looks really neat.

actually its much more wine-red than the cam photo.

according to i think the correct color is: 'purple, plum, magenta, maroon'

i got it labeled as'violet, transparent'.

the next one will be something more blue.

if everything goes as planned, i will have some of these on the 27C3.

please contact me* before, if you already know you want one, so i can plan ahead.

ps: do you want wooden ones as well?

heekscad heekscam 0.14.1svn ubuntu packages /chrome/site/flattrbutton.png

after quite some absence, i've revisited heekcad.

not only due to public demand here at raumfahrtagentur, but also due to the still existing problem of 'using different cad tools will do weird things with my files' - i rebuilt heekscad and heekscnc and its libs.

what changed in the last half year?

  • pycam got replaced by opencam.
  • loads of bugs fixed (seemingly, feels more solid)
  • new features with new bugs added :)
  • a ton of stuff i havent mentioned..

the packages seems to work for me so far, please test and report your experiences.

these are packages for ubuntu karmic (9.10) x86

and for ubuntu lucid (10.04) x86

if you don't know heekscad, take a look at the nice new website

updated: added packages for lucid

the agency now got a physical flattrbutton


first it there suddenly was a stencil...

... and then the leftovers made for a nice real-world flattrbutton :)

Geneva Wheel

A little practical mechanics with the laser. The Geneva Wheel. CAD in QCad, using the picure in the Wikipedia page.


Pappelsperrholz von Obi, 4mm Stärke, geht mit 8mm/s (Update: oder 2x 20mm/s) halbwegs passabel durch. CAD-Daten komplett in QCad designed von Jonathan. (Und ich hab endlich verstanden das Warhammer 40k nicht viel anderes als Plasteritterspielen mit ausgefeilten Regeln ist).

First try with marking material

... on the back of an old iPhone.

Lessons learned: material needs to be more evenly spread.

Data sheet of used marker material LMM 14:

first blood

its lazzoring!

the machine still needs some more alignment. some parts were not lasered through completely and needed some work with the cutter to come out.

put it on thingieverse, gismo!
