Read the blog (yes Chris, I know it's slow...)-- (URL) made a little video game. I know that others have made on-screen games, so I just went with it. As soon as I saw the 'aim' pic and the 'rabbit' pic, I knew I just had to do this. So with much (...) (18 years ago, 8-Mar-07, to lugnet.org.ca.rtltoronto, lugnet.robotics.nxt)

| | Force/Tension feedback
|

In "Spike", a touch sensor at the end of the stinger provides the logic to stop a motor when it is pressed. How about without a touch sensor? How can the motor/rotation be programmed to provide tension or force feedback? If I tell the motor to move (...) (18 years ago, 5-Mar-07, to lugnet.robotics.nxt)

Hi Guy, You inspired me to do a ping using NBC, but I have run into trouble. I get a -35 (ERR_COMM_BUS_ERR) when I try to read more than one object reading. The code is long, so I'll just put the basics of what I am doing here to see if anyone (...) (18 years ago, 4-Mar-07, to lugnet.robotics.nxt)

I'm very glad to know you got it working again. Incidently, the '1.02' I was talking about isn't the version number on NXT-G itself, but on the USB driver it uses.
