Hello All, I have just purchased a new TYCO 9.6V Zig Zag car. It seems to have a fairly good base w/treads. I connected it to the handyboard (after gutting it and extending the wires ).

If, (...) (27 years ago, 1-Aug-97, to lugnet.robotics.handyboard)

The best places are the mail order hobby stores. They have the widest selection of servos and very good prices. The two I recommend are Tower Hobbies (www.towerhobbies.com) and Hobby Shack (www.hobbyshack.com). Either of these sells servos cheaper (...) (27 years ago, 1-Aug-97, to lugnet.robotics.handyboard)

Hey there, sorry I forgot to mention a few things to you: Digikey stocks the Optrex LCDs, they're about $12/ea, and since you're probably ordering from them anyway, it's no problem. The difference between the B and UB versions, I think, is that the (...) (27 years ago, 29-Jul-97, to lugnet.robotics.handyboard)
