| | | | | There are two very easy methods of making LEGO compatible 9V connectors. 1. Use Dacta #779897 9V Connecting Leads (3 pieces) @ $12.25. Cut the leads to the appropriate length for your use. Break a male 0.100" strip header (DigiKey #929834-01-36-ND) (...) (25 years ago, 4-Jan-99, to lugnet.robotics)

Further, if it were pluggable into regular LEGO bricks, the model would not *demand* construction oriented (...) (25 years ago, 4-Jan-99, to lugnet.robotics)

| | | | | Jasper - - You are correct. The HandyBoard is 14X10 studs and is very easy to incorporate into LEGO robots. I move mine between a tracked sensor test-bed and a wheeled cat terrorizer. The wheeled robot will also accept my RCX (and makes louder (...) (25 years ago, 24-Jan-99, to lugnet.robotics)
