(...) I have a proposal that would theoretically allow an RCX to use 49 motors and 147 active sensors (or 588 switches!). This has the potential to control an entire Ball Contraption or railway! The idea may be expandable to four times those (...) (20 years ago, 27-Jan-05, to lugnet.robotics.rcx)

hi so IMHO don't expect more outputs because of the power 3 motors + 3 sensors + mainboard have to be powered by bateries some time ago i proposed to make connectors smaller (URL) good think is the size of these connectors of course second is that (...)

| | RCX3 - Can extra hardware functionality be added?
|
|
Having had a good look inside my RCX, I'm thinking seriously about what is really possible in the same space envelope, whether extra ports or functions could be added for RCX3. I think it's useful for us to know what's inside the RCX, especially if (...) (20 years ago, 21-Jan-05, to lugnet.robotics, lugnet.robotics.rcx)

Here's my drawing of the RCX IR transmission circuit (receiver circuit to follow soon): (URL) With the voltages as shown, the RCX is not transmitting. The IR LEDs are powered by a 600mA current sink. I haven't measured for waveforms yet - the (...) (20 years ago, 20-Jan-05, to lugnet.robotics, lugnet.robotics.rcx, FTX)

Folks, I've been fiddling around with how BricxCC and NQC talk to the RCX when using the USB tower. It's because of several users experiencing problems when trying to download programs from within BricxCC (using NQC behind the scenes). Depending on (...)

Here are my drawings of the RCX sensor port and power supply circuits, complete with measured voltages from inside the box. These are averages measured with a DMM, not an indication of peak waveforms. I might use an oscilloscope later if there's a (...)
