(...) This is an interesting subject and one which generates some interest every so often. The conventional assumption would be that you are talking about LIDAR. The thing is, even if simple plans where available, would you be able to use them to (...) (20 years ago, 4-Aug-04, to lugnet.robotics.rcx)

Hi I'd like to build a laser distance sensor for my mindstorms robot. Does anyone know if any plans of circuits of such sensors exists? Andreas (20 years ago, 4-Aug-04, to lugnet.robotics.rcx)

(...) What are the differences between 1.0 and 2.0 firmware? I prefer VB to the supplied software anyway, so that makes no difference. Mark (20 years ago, 3-Aug-04, to lugnet.robotics.rcx, FTX)

The Mindstorms SDK 2.5 is still available, which includes the 2.0 firmware. If you don't want the actual 2.0 version of the graphical programming software then this should be all you need. (URL) (20 years ago, 2-Aug-04, to lugnet.robotics.rcx, FTX)

(...) Yes, I suggest making an inertia circuit for use with trains, but for cars something else might be better. In RCX float or braked modes the power H-bridge flywheel diodes will brake the motor, but in high power applications, how often is float (...) (20 years ago, 1-Aug-04, to lugnet.robotics.rcx)

(...) Good idea. It will be difficult, though, to determine the differnce between braked and floating motor setting, or am I wrong? Or maybe one should measure the resistance on the RCX terminal, when no voltage is put out. I thought of invading the (...) (20 years ago, 1-Aug-04, to lugnet.robotics.rcx)

I'd like to upgrade my RIS software to 2.0, but it would appear that Lego no longer sells it. (URL) says "Sorry this item is not available in this country."

Have anyone tried to add an external motordriver to the RCX ports, so you can use the powerful 3Amp motors from the 8366 RC car on the RCX? (20 years ago, 26-Jul-04, to lugnet.robotics.rcx)
