I had already posted this on the other keyboard community but after a few beers tonight, felt I should share it here too. I built this last weekend and test drove it at work all week. I think I really like the Robins but probably not as much as my beloved Sunsets.
The layout is for my Ferris but it's mostly adapted to 36 keys as well. It's based a bit on Miryoku and KKGA(I think that was the name). I also took heavy influence from Mental's symbol layer with the finger roll bigrams. I do have a gaming layer but it's sort of always changing depending on the game I am playing. Right now it's Dyson Sphere Program so my second gaming layer is shortcuts for like belt levels and copy/pasting buildings.
We have an old crockpot that my wife uses to dye yarn with. I used that with a packet of iDye Poly since that dye can be used for plastics. I dumped it in with some water and let it heat up to medium-high-ish. You can go fairly hot but too hot might warp the plastic(I think this more applies for MX style keycaps though). I let them soak in the warm dye for maybe 25 minuets, but scooped some out occasionally to check the color. They start to take almost immediately but you will get a pastel color. The longer you go, the deeper the color.
If you search YouTube for dying plastic with iDye Poly, you will get a lot of hits.
