Hi,
I'm Jordi and my nick name is autocet, from Barcelona (Spain)
For years I make my personal way of PCB 100x40, based in a quarter of eurocard 100x160. Or half, or three quarters...

My idea is to continue developing as these PCBs
If someone likes the idea, I invite you to use this format to share designs, with no restrictions like open hardware and DIY.
These restrictions are:

for assembling with spacers used as power bus


Or this other restrictions:

For batery assembling over cupper bars. (for instance)

I offer a lot of ideas:

from a form associated instrumentation for desktop,

to a crazy way to make a CubeSat,
Since I use this format I have not never thrown away any more pcb
It could be someone interested in going along?
thanks for your answers
