I figure LEGO must owe you about a million dollars. Getting this kind of publicity before Christmas in the New York Times is worth a ton of money. But not at all to take away from your acheivement. You earned the recognition. But tell us: how did (...) (23 years ago, 11-Oct-01, to lugnet.robotics.rcx)

(...) Hey, congratulations! That is so awesome. When I first saw your cube solver a months ago, I thought it was very clever. Back then I don't think you had integrated the camera. I hope you have the article framed or something! -Kekoa (23 years ago, 11-Oct-01, to lugnet.robotics.rcx)

All - My PC-RCX hybrid Rubik's Cube solving robot made it into the New York Times today ('Circuits' section 11 October, 2001). I couldn't be happier. Check it out online at (URL) .

ArsyExCC? Now that one's not bad. :-) Thanks for (...) (23 years ago, 9-Oct-01, to lugnet.robotics.rcx)

FYI - I just noticed in the component specs from Sharp that the GP2D12 (and GP2D15 for that matter) have a built-in voltage regulator. See (URL) is an external regulator a necessary precaution? Just curious... - Gareth (23 years ago, 9-Oct-01, to lugnet.robotics.rcx)
