Lasercut Plywood Board for Raspberry Pi

Need a quick way how to attach a LED, a push button and two resistors to the Raspberry Pi header? One way is to use some ‘flying’ wires. Or to use three pieces of lasercut plywood for a nice looking Raspy extension board:

Breadboards for electronics are a great way to make a temporary circuit. But what if that circuit should last a bit longer, and there is no time to create a ‘real’ PCB? I have found that making a plywood lasercut board is actually another way:

What triggered this was the need to have around 30 boards for students to wire a LED and a push button to the Raspberry Pi. But there was no real way to get a board done over the weekend. Instead I have cut things out of plywood:

The boards are designed in Inkscape with three pieces:

  1. Top piece (left) with a ‘silkscreen’
  2. Middle piece as a spacer
  3. Bottom piece (right) to as a distance holder to the Raspy bottom

Components are THT and holes keep them in place:

The wires on the bottom are soldered together with he header on the side:

One pice is used as a spacer:

And finally with the bottom board to close everything:

The three pieces then are glued together to build a block:

This nicely plugs now on the top of the Raspberry Pi board:

That hack worked out very well: it is solid, very cheap (I re-used small scrap parts of plywood) and it works nicely :-).

Happy Woodboarding 🙂

  1. Nice! A laser cutter is still on my wish list. I picked up a laser marking system (it went for $160 at an asset liquidation auction and I couldn’t pass it up at that price) and it has enough power to mark stainless steel, but alas it’s not much good for cutting anything. For now I figure I’ll just confuse my competitors by sanding off IC markings and lasering on new ones. 😉

    • How much power (W) does your laser have? In any case, a good laser engraver for $160 sounds like good deal. With my 50W machine I can cut plywood and PMMA up to 4 mm in one cut, for more I usually do a second pass which works fine too.
