 | | Chaining multiple RCX's output to input —Eric Brok
|
| | | While attending Michael Gasperi's workshop at Mindfest it occured to me that, from his investigations, it should be functional and harmless to connect the output of an RCX to the input of another RCX. Last night I connected my RCX to my Scout and it (...) (25 years ago, 27-Oct-99, to lugnet.robotics)

Using a motor as a tachometer has come up before and I used to be worried about this causing damage. I have it from the LEGO engineers I met at mindfest (...)

| | | | (...) Pop a 10K ohm resistor in series with the motor. On my quick test with a variable resistor I got a value of 513 with the resistor at 9.7k. With a 10k resistor, the RCX raw value is now flickering between 510 and 511. P.S. same with the older (...) (25 years ago, 27-Oct-99, to lugnet.robotics)

The 10K you put in series with the motor will put the voltage at half way (2.5V) (...) (25 years ago, 27-Oct-99, to lugnet.robotics)

That allows the additional advantages that: - the (...) (25 years ago, 28-Oct-99, to lugnet.robotics)
