I must not be good at online games because I only have a regular $10 keyboard. I’d better go get a “gaming” keyboard immediately

This hack is awesome though

schobi: A typing aid system would just be useful for people who actually look at their keyboard while typing. My keyboard is usually below the table where i can’t see it.

_matt: I’ve also thought about lightsout (because i really like that game :)). But the keys arent in a 90 degrees grid. Actually you could just play it perfectly well on an 3×4 region on the numpad.

cool hack …

which keys do you light for beeing useful? what about a typing aid system?
-> Light the keys that are more probable depending on the last characters entered.

There are some powerfull modeling tools for text compression (context tree weighting) that look at the last 5-10 characters and assign probabilities for next characters.

This thing is so cool. A much more affordable alternative to the optimus maximus keyboard. The next step is to take it RGB. That would be a killer product. I would pay $200 for an RGB version. Even if it was just RGB on a-z.

For $150, that keyboard should already have this functionality.

He used a 68HC908JB8…brings back memories. It’s still a good chip for low-end USB projects. Cheap, has USB hardware built in, meaning that you just grab the interrupt and see what bytes you just received. While the effective instruction rate is around 1 MIPS, it still compares well against a similar-cost setup using software USB on an ATTiny, since the AVR is spending nearly all of its time on USB. The downside is development…he uses Codewarrior and assembly, but you can actually find a free HC08JB8 assembler from PE-Micro. The chip supports in-circuit programming, but you have to set a few jumpers and apply 11 volts to program it.

this is really cool.

the thermal effect though, that would be very bad to have enabled when typing passwords

I can imagine a perfect game to play on that keyboard…. light’s out.

Really neat hack, btw.
