Forsken now only reside irl at Kontrapunkt (Norra Grängesbergsgatan 26).

Our thing at fbrkn/stpln, has ended. Where they nowadays trying to organize a Fablab -thingy. Arduinoverkstad has largely abandoned that place also.

And forget about Bageriet hackspace in town, only lasted a few month last year. Punks had a party sabotaged for neighbors who complained.

But at Kontrapunkt, things is as usual. Still having openhouse every Tuesday evening. Atm very low irl activity, on this Malmoe hack/maker -space. The number of visitors to us, can often be counted on one hand.

Kontrapunkt so called: “kontrapunkts -kreativa -verkstäder“, have other workshops same building. That also have openhouse at same day (Tuesday evening). They organize people-kitchen, concerts, croquis, guitar -builders (woodwork), screen-printing, and various political activity, -mostly leftist thingy, dono..

The assumption from other visitors seams tobe, that we only hacking computers. But I don’t know, don’t wana squeeze out alphaomega. Because they are naked in the other room, croquis.

Wish to think, if you have idea for any project, making things, trying to solve problem, this is the place you should goto. Our core purpose maybe is to do stuff with opensource or openhardware. But having more than one hear, we trying tobe open and constructive. Take a peek at the wiki, check the mailing -list, or irc. -that actually have some activity if you idle awhile. And if you have a grand idea howto get more activity, visit us Tuesday evening.

Maybe not everybody like to document what they do, is sortof a minimalist myself on that. Working on it. Okey, this was this blogpost.

-A note to the picture, The “K” was missing, snuffed, used “X” to misspell to “forsken”. Btw Kontrapunkt setting up lots of bars and lockers, dono how “open..” that may appears. These magnets was made here, sorry if they not in the wiki.

 

Forskningsavdelningen have been working on a new vectorization algorithm specifically designed for tracing PCB layouts, keeping CNC routing restrictions in mind to produce G-code that executes with minimal dwelling-requirements. This is a preview of stage-1 (vectorization) output of a sample input containing a large variety of potentially problematic designs:

Bitmap PCB to G-code conversion, stage 1

The algorithm is complete, and now begins the work of writing stage-2 (tool-size correction) and stage-3 (g-code generation). The finished solution will allow autonomous conversion of any PCB bitmap image to G-code for tracing, drilling and outline milling. Output options will be one program per operation and drill-size, or a single program with tool-change operations.

 
CNC remote controlOn Thursday 5/5 and Tuesday 10/5 STG held a basic CNC milling workshop using the Roland MDX-40A at Fabriken. We went through the basics on how to set up and calibrate the machine, attach a workpiece and specifying geometry, generating toolpaths of a couple different types (holes, surfacing, from 3d-models) and performing the actual milling.

This will be followed by a PCB-engraving workshop on Sunday 22/5, and also advanced workshops (dates not set, will be posted on the list) including some basic CAD and two-sided milling with supports and using guide-pins.
