Yes -- I didn't think very hard and in retrospect it's fairly evident that Jan-Sipke's code is just the starting step. Sorry for being such a blunderhead. (Jan-Sipke and I have been exchanging some private messages and I think he's closing in on a (...) (27 years ago, 14-Feb-98, to lugnet.robotics.handyboard)

Everyone is complaining about the price of LEGO motors. There is a new product, a gear reduction motor, that is a great value. It is a super efficient DC motor with a built in gearbox that can be used for direct drive, or with one stage of gear (...) (27 years ago, 13-Feb-98, to lugnet.robotics.handyboard)

(...) Sipke obviously realizes that more work is needed, and justs want to get to step 1 first by recognizing the interrupt. That is exactly what I would do too. I've been thinking about writing an interrupt-driven serial receive routine too, but (...) (27 years ago, 13-Feb-98, to lugnet.robotics.handyboard)

Jan-Sipke, You're really pretty far away from having this work. It's not just a matter of redirecting the serial interrupt; when you get there, you have to: * store incoming character in a buffer * advance the buffer pointer * check the buffer for (...)

Hi Greg, I have been using LEGO 9v motors for a few years and I am very pleased with the results. I run freshman and sophomore engineering design and computer science courses using LEGO kits and HB's. The motors are well worth the price if you are (...)
