Back to hacking. This is part of what defines NB and we should all do.<br>
So after this way to long preamble, I am telling you what I am hacking<br>
right now.<br>
<br>
Over New Years' eve, I was playing with the Beaglebone PRU to generate<br>
nice, realtime-clean stepmotor steps<br>

Was easier than thought, and works quite well<br>

<br>
Since that worked well, I designed a board together with Jake that we<br>
call 'Bumps'<br>

<br>
They arrived in the meantime (OSH-Park is has a nice quality!)<br>

<br>
... so hopefully on the upcoming weekend we'll find some time to<br>
solder them together. For that, there is the plan to use Jakes 3D<br>
printer/dispenser (he did a 5MoF on it) and dispense solder paste on<br>
the board. For that I wrote a quick program to convert some KiCAD<br>
output to GCode for doing the dispensing action. Here is the code for<br>
that:<br>
