 | | Reset on the HB
|
|
Could someone tell me where the reset button refered to in documents for the Handy Board is? I know the master reset is the on/off switch. TIA. Steve (24 years ago, 6-Jul-00, to lugnet.robotics.handyboard)

|

The 6.6nF was the capacitance measured for the two 6.8nF capacitors that I have managed to get (rated as 10% tolerance). The problem is that the parts listed for the HB are 2% tolerance 6.8nF capacitors which gives a lowest value of 6.6664nF which (...) (24 years ago, 6-Jul-00, to lugnet.robotics.handyboard)

(...) Yes. Capacitors have typically very loose tolerances anyhow; usually 20% unless you buy specifically selected samples in a tighter tolerance. The 6.8 is a standard value while the 6.6 you have is likely a specially selected non-standard value. (...) (24 years ago, 6-Jul-00, to lugnet.robotics.handyboard)

Can any body tell me if a 6.6nF capacitor will do to replace the 6.8nF in the IR Transmission circuit (Fred?) ?. Thanks in advance. John Hatton (24 years ago, 6-Jul-00, to lugnet.robotics.handyboard)

| | HB to Comms board cable
|
|
Is there a 'best' length for the telephone cable between the HB and the Comms board. I am about to start construction and I was wondering if there was a maximum length for the cable and if a particular length was recommended. Thanks for your help. (...)

Gruezi/ Hi, (...) Instead of using the serial port, how about using the HP4**x IR port? I recall there being HP4**x programs that emulate IR remote controls which should be easy to modify (?) for general-purpose communications. Marco A. Assfalk de (...)

| | Handyboard startup problems
|

Hi all, I'm having some problems with me previously functioning handyboard. I'm using a standard board which has worked fine for nearly a year. Recently it didn't get any use for awhile and the batteries ran down. After charging them for 18+ hours I (...) (24 years ago, 5-Jul-00, to lugnet.robotics.handyboard)

(...) Not knowing what parts the HB uses, but assuming it is something like a polystyrene cap, then I think I have some in my component drawer. Send me your address, and I'll stick a couple in the post. Best Wishes (24 years ago, 5-Jul-00, to lugnet.robotics.handyboard)

This is my routine to use the Vector 2x with my board (see link below my name) with an I/O expansion board connected. You will need to change the I/O port #defines to work with the Handy Board I/O ports on your expansion board, but other than that (...) (24 years ago, 4-Jul-00, to lugnet.robotics.handyboard)

Hi Robert, It has been over a year since I have had the vector 2x connected to my board but if you follow the instructions that Tom Brusehaver posted in contributed software everything should work ok. You will have to connect to one of the motor (...) (24 years ago, 4-Jul-00, to lugnet.robotics.handyboard)
