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 (...) (26 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. (...) (26 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 (26 years ago, 6-Jul-00, to lugnet.robotics.handyboard)

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 (...)
