someone will correct me if I'm wrong but aren't those led's special low power ones? will 'a similar one from radio shack' work in this application or does it have to be the same part number as specified in the parts list? -patrick -----Original (...)

|

Hi, I'm building my HB's Interface/Charger circuit. My problem is in the serial circuit. I built it and it passed the test only once. After that somehow my power led didn't work anymore and voltage regulator gets very hot (although it passed the (...) (24 years ago, 1-Aug-00, to lugnet.robotics.handyboard)

Hi , when I run modified servos from the motor ports both leds light in fwd and in rev at the same time either when the robot is moving fwd or reverse? How can I correct this? It works correctly with lego motors? Why not with the servo? Thanks (...) (24 years ago, 24-Jul-00, to lugnet.robotics.handyboard)

I have recently come across an interesting IC being sold by RS Electronics in the UK. It is an IR transceiver IC which effectively gets connected to a normal serial UART and then just acts as though there was a physical cable in place. The IC does (...)

| | Re: Encoder routines

I can offer some input on this, as I have used both the Rug Warrior approach and the Handy Board approach that you describe. As far as which method has an advantage over the other is probably a qualitative assessment that is application driven, and (...) (24 years ago, 20-Jul-00, to lugnet.robotics.handyboard)

| | Encoder routines
|

I've looked at the shaft encoder routines and it seems to be getting the encoder voltage at certain times and using that to keep track of ticks. In the past I have used an input capture to keep track of ticks. Is there a certain advantage of one (...) (24 years ago, 20-Jul-00, to lugnet.robotics.handyboard)

Hi all, I used Gary Livicks routine in connection with the GP2D02 Sensor. When there is no obstacle in front of the sensor the LDC shows: "range is 77". Is that normal. Shouldn't the LCD display zero? If it is normal can you say me why? Thank you (...) (24 years ago, 19-Jul-00, to lugnet.robotics.handyboard)
