 | | Re: Connecting a non-Lego motor with external battery to the RCX
|

(...) If the motor runs on 9V anyway, just hook it up to RCX directly (assuming it only draws 500ma). If it needs more than that, hook an external battery up to it via a power transistor (either bipolar or FET). You'll need a resistor in series with (...)

|

Hi, If you have the SDK2 for the RIS then you have all you need to develop for the Scout. It uses the RCX 2.0 firmware, and all that is different is the following: 1 x built in light sensor (takes away one input). 1 x runnable program mode (select (...) (23 years ago, 18-Feb-02, to lugnet.robotics)

I'm not sure if anyone is trying out my multiplexor patch, but thought I'd let you all know that I posted a new version which works better and solves some problems in the earlier revision. The patch is available in the legOS patch section on (...) (23 years ago, 17-Feb-02, to lugnet.robotics.rcx.legos)

hi John, everything seems to work fine now, I couldn't get it slowed down. A funny effect, everytime you start BricxCC, it sizes to the previous size, ok. Now opening a file (from the recent file list), BricxCC fills the whole screen. Thanks for the (...) (23 years ago, 17-Feb-02, to lugnet.robotics.rcx.nqc)

(...) Also, there can be contact problems between the tabs and the circuit board. They are not soldered on, they only press against two square contact areas in the corners. If they are a little bent they can loose that contact, which happened to my (...) (23 years ago, 17-Feb-02, to lugnet.robotics)

(...) Definitely. I was having problems with my light sensor (this was before I was using legOS) - the 'test panel' in the Mindstorms software wasn't reading it, and the RCX just showed a boolean 1 on the light sensor port. So I called LEGO, and (...) (23 years ago, 17-Feb-02, to lugnet.robotics)

hi matthias with two "t"s, hi list! (...) i didn't mean the mcu - it's obvious that the "digital part" (as i called it) has to be regulated to 5v. i meant before that: motor controllers, probably active sensors and the like. the point is this: the (...) (23 years ago, 17-Feb-02, to lugnet.robotics)
