That's a pretty fun project, but it's a bit sad that the electronics were lifted form an existing keyboard.

Are mindstorms flexible enough to emulate USB HID?

edit: it looks like mindstorm EV3 is bluetooth-enabled. I don't know the details, but it might be possible to get it bound as a bluetooth keyboard, and thus to have a fully functional "pure-lego"[0] bluetooth keyboard.

[0] the mindstorm EV3 brick runs a Linux distro on a 300MHz ARM9 core with 64MB RAM and 16MB flash (plus a SDHC slot). Whether this remains "pure lego" may be up to debate.

So basically they took the keys off of a keyboard and glued some legos on the keys instead? Not really impressed.....

I was disappointed when I saw the base was taken from a keyboard (I was expecting that to be mindstorm based as it was posted on HN). But the mechanism for the keys is very cool and well designed, it's a massive understatement to say it's just Lego pieces glued on the keys
