Firstly you will need some laser rubber, which can safely be cut on the laser cutter without loads of fumes.

I had to buy this in bulk as shipping was quite expensive. Its around £7 a sheet, plus £6 p&p, plus VAT.

If you would like a small bit to try then I am selling the excess from mine at £5 for an A6 piece (1/4 A4 - enough to make a load of stamps). Email matt_AT_re-innovation.co.uk.

You will also need a rubber stamp ink pad and some structure to hold the stamp (a block of wood with a handle). I used this automatic inking rubber stamp as it was going up for grabs.

Make your image on your favourite graphics package. The image should be just black and white, as there is no graduated colour on a stamp. Make sure its the correct size.

Test it out on a piece of wood - does it look OK?

The SMD version of the badge was designed for more advanced users so they can learn to do surface mount soldering or use an SMD oven. The circuit is a [http://www.talkingelectronics.com/projects/FlasherCircuits/Page83FlasherCircuitsP1.html Flip Flop Two Transistor Flasher].

To cut the rubber, the settings I used are:  <del>speed 50, power 200. This made a reasonable depth (around 1mm).I would suggest using even slower speed to make it even deeper. I will check next time with just 20 as the speed.</del> '''Edit:''' Making the laser go slowly makes the rubber heat up and expand and causes distortion on the cut surface. After loads of attempts, I have found the best settings to be high power (400) and high speed (200) and then do two passes with the laser.

Cut the stamp out with a sharp knife. Any point edges might affect the stamp, so go pretty close to the raised surface. You can see in the next photo that I get a load of ink around the edges. I should either cut it off or stick it down onto a more rigid surface.

Overview

These are notes and files relating to the 'Learn To Solder' Robot Badge. This badge kit has been produced to use at events as a simple soldering exercise and promote the hackspace. This badge was based upon a simple flashing LED badge that was seen at UK Maker Faire 2011 in Newcastle. This robot shaped badge was designed by Matt Little based on an idea by Rob Keating from PCB manufacturers, Beta Layout. Beta Layout produced a number of batches of these PCBs for Nottingham Hackspace.
