A new version of my Power Functins library and PWM remote are now available at: (URL) There was some code cleanup and fine tuning. The PWM remote program now goes from slowest to fasted speed. give it a try and thanks for all the feed back so far. (...)

Nice idea. I wonder if it is possible to make the Wiimote talk directly to the NXT over Bluetooth... (17 years ago, 28-Jan-08, to lugnet.robotics.rcx)

Recently, I've bought WiiMote (Nintendo Wii Controller), which can be tethered to a regular PC via Bluetooth. You can then use for example this library - (URL) - to read WiiMote buttons, IR and accelerometer data. I've combined this with a simple (...) (17 years ago, 27-Jan-08, to lugnet.robotics.rcx)

(...) Very good. Have you done experiments to map the power level settings to RPM? I am guessing that each of the 7 steps sets literally a power level (PWM width) and not a speed. Have you done experiments under load to see what happens to the speed (...) (17 years ago, 27-Jan-08, to lugnet.technic, lugnet.trains, lugnet.robotics, FTX)

Has anyone had this issue before; I have a NXT with the rechargable battery pack and everything has been working fine. I've charged it twice with out issue, but then last night the NXT complained about a low battery but when I hooked it up to the (...) (17 years ago, 27-Jan-08, to lugnet.robotics.nxt)

(...) Could it be that the long range mode of IR is not set (I saw no reference to range setting in your source, and I don't know the default state). Despite the difference in carrier frequency, the RCX 1.0 and RCX2.0 are able to dialog albeit with (...) (17 years ago, 27-Jan-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics)

(...) I don't know if the instructions are on-line (publishers don't always like that), but you might want to have them build something similar of their own, just to help in designing something.

(...) I just tried the new commands with a home-made NXT-controlled IR remote. I was able to get them to work without a problem. I verified the single-output PWM mode, which starts a motor at a given power level, in which it stays indefinitely (...)

(...) i have not really spent a lot of time trying to figure these modes out. i was more concerned with getting the PWM to work correctly. i'm going to spend more time testing this and will let you know. bob (17 years ago, 26-Jan-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics, FTX)

(...) Glad it worked for you and thanks for the heads up on the RCX 2.0 problems. i don't have a 2.0 RCX to play with so i'm not sure if it is a timing issue that can be resolved or what. i was very excited the first time i got my RCX to talk to the (...)
