|
| (...) Thanks Eric, I have a progress report, boss.... ;^) I have completed two compressors. The first is basically a two large pump compressor driven by two RC racer's motors (very powerful). This compressor is implemented with one large piston and (...) (20 years ago, 31-Jul-04, to lugnet.technic)

| | Re: Measuring robot turn angle

Since you can guarantee that both axels turn the same amount, a single rotation sensor should be (...) (23 years ago, 10-Jan-02, to lugnet.robotics.rcx.legos)

But your wife is correct--the tool has no predictive power because its predictions are so (...) (20 years ago, 1-Nov-04, to lugnet.off-topic.debate)

| | RCX Firmware Speed

The interpreter is very slow because of all the overhead required to execute a (...) (23 years ago, 10-Apr-02, to lugnet.robotics) !

| At BricksWest, Steve and I had some discussions about the game rules. One thing Steve has been trying to come up with is a way to eliminate plotting moves since this slows down the game the most. The problem I would have with eliminating this is the (...) (23 years ago, 24-Feb-02, to lugnet.gaming, lugnet.pirates)

| | Re: Voltage Sensor
|
| Hello Tom, (...) Yes. You need a low impedance output driving 0..5V into the RCX, thus overriding its internal pullup. (...) Actually, I should have written "resolution" instead of "accuracy". The 10..15V range spans 5V with 256 steps, giving you a (...) (22 years ago, 17-Sep-02, to lugnet.robotics)
