(...) SNIP (...) Newark electronics used to sell a humidity sensor based on this principle for about $ 12. It should still be available. I believe it was made by Phillips. Basically the variations in capacitor value is used to vary the frequency of (...) (25 years ago, 12-Jan-00, to lugnet.robotics.handyboard)

I have several sensor questions. I would like to use my miniboard as an engine management system. At the present time, I have a small 2 cycle engine from a weed wacker that I would like to control. I would like to have the miniboard gather some (...) (25 years ago, 12-Jan-00, to lugnet.robotics.handyboard)

| | SPI Port

Hello - I have two sensors that require the SPI port: the Sharp GP2D02 IR sensor, and the Precision Navigation Vector Compass. I'm hoping that someone can tell me how to use both of these sensors at the same time, on the same port or by using some (...) (25 years ago, 12-Jan-00, to lugnet.robotics.handyboard)

HI Any of you guys out there in robo land have any good PCB designs for high powered motor driver, IRPD's or a nice Handy Boardish thing that you dont know what to call. Thanx -roboman PS Got a PCB etcher system for XMAS and want some PCB designs (...) (25 years ago, 12-Jan-00, to lugnet.robotics.handyboard)

(...) 'Trace', and 'track', are common parlance, for the wiring built onto the printed circuit board inside a unit. So the post is saying that you have to actually cut the copper 'tracks' inside the unit itself. Best Wishes (25 years ago, 11-Jan-00, to lugnet.robotics.handyboard)

(...) I've seen "trace" used a couple times as regards the Handyboard, concerning the leads from/to the inputs, I think??? What does it mean, what are they? Thx :) - Scarius (URL) (25 years ago, 11-Jan-00, to lugnet.robotics.handyboard)

I just managed to connect a Sharp GP2D12 to my Handyboard. The advantage compared to the GP2D02-device is the analog output which does not consume processing power for clocking the sensor. Further information can be found at: (URL) (25 years ago, 11-Jan-00, to lugnet.robotics.handyboard)

| | RE: More servo stuff

I had the same problem. The servo would run fine if the program was not doing anything else. But if I was updating the pwm to the motor ports then the servo would jitter. I figured it was because the extra overhead was screwing up the timing on the (...) (25 years ago, 11-Jan-00, to lugnet.robotics.handyboard)
