|
|
(...) The brick version doesn't really mean a lot (other than that version 1.0 bricks had the external power jack). If you download the firmware from the 2.0 SDK then your 1.5 brick is an RCX 2.0 and it will work perfectly well with NQC, BricxCC (...) (23 years ago, 22-Oct-02, to lugnet.robotics.rcx)

I had a link to the schematics and working on an RCX, I thought, but I can't find it. We have an RCX that's "A" motor port is malfunctioning. If it's a loose connection, we'd like to re-solder it. Anybody have a link to nice, clear pictures of what (...) (23 years ago, 22-Oct-02, to lugnet.robotics)

Just in case people are a bit confused by the schematic, the circuit would be needed for each device that will participate in an RF bridge. I abandoned the idea of using two different frequencies because: 1) As soon as you attempt communication (...) (23 years ago, 22-Oct-02, to lugnet.robotics)

Hello, I am starting to look at my mindstorm again. It is version 1.5 and I have prev. used NQC and RcxCC. What should I use now? How about the new sdk 2.0? Can I use that one? Can I use the new versions of NQC and RcxCC? Hope someone can bring me (...) (23 years ago, 22-Oct-02, to lugnet.robotics.rcx)

I just noticed at least one glaring error with the new schematic... Say, for argument, an RCX sends "1001", which, in IR, would be "0110". The IR detector of WIRRL would do nothing for the first bit ("0"), but the next bit ("1") should be sent over (...) (23 years ago, 22-Oct-02, to lugnet.robotics)
