  Re: vector 2x compass
 
Mike, U11 is the motor driver nearest the start button that drives motors 2 and 3. The #2 pin is the second pin back on the chip nearest the start button. See page #2 of the Handyboard assembling manual. I followed Tom Brusehaver instructions at the (...) (27 years ago, 22-Mar-98, to lugnet.robotics.handyboard)
 
  vector 2x compass
 
I am trying to wire up my vector 2x compass and i had a question. It looks as if everything is wired to the SPI port, however to actually poll the compass you need to make p/c go low (pin 5 on the compass) On the schematic it shows that i should (...)

  Re: HBridge LMD18200
 
Its a MOSFET based bridge, the Vgs potential needed to put the FETs into full enhancement mode is 11.2v or thereabouts. At lower voltages the FETs operate in their linear range (their Rds value goes up) and they dissipate much more heat. (As Rds (...) (27 years ago, 20-Mar-98, to lugnet.robotics.handyboard)

Hello, First thanks for your answers regarding H-Bridges and especially the LM18200. This H-Bridges would be used with 12V DC motors which can sink up to 12Amp each and I have plenty of room to put them. But there is still something that puzle me : (...)

  IR input sensor
 
Hey! I was wondering if anyone has written any sort of fairly simple program that can detect another handyboard by using the IR input sensor. Does this require anything else besides maybe an analog IR sensor and the sensor on the board? If you could (...) (27 years ago, 19-Mar-98, to lugnet.robotics.handyboard)

  Re: Polaroid sonar connector
 
Easy solution. Why waste so much time looking for connectors. Just remove the connector and solder some wires to the board and run those wires to whatever kind of connector you want! -----Original Message----- From: Will Bain <willbain@cs.umt.edu> (...)

Hi talking about the H-Bridge.....we are building one here for a 1.5 kW motor with maximal power output of 2.2 kW. This one works with 400V but is also developped for a current of a little more than 10 A (actually 15A). It will be chopped with a (...) (27 years ago, 19-Mar-98, to lugnet.robotics.handyboard)

This suggestion isn't even close to what you require, but it may meet the needs of others on the list who are looking for an alternative H-bridge: (URL) can go to 3.5A at 35vdc, and is serially controlled.
