  Re: battery voltages
 
(...) Yes, and the current capacity would be the same, since excess voltage gets dissipated in the HB's voltage regulator. -Fred (29 years ago, 6-Feb-96, to lugnet.robotics.handyboard)

  Re: HB died - HELP
 
Keith, You may have shorted something out while connecting up the battery. I've seen this before, and parts do fry if you connect them to 9.6v. If while you had the battery ground lead connected, you just brushed the +v lead onto some pins, that (...) (29 years ago, 4-Feb-96, to lugnet.robotics.handyboard)

  Re: hmph
 
(...) Be careful. Cheap RC cars tend to use 3v motors that want to draw a fair bit of current. Expensive RC cars use motors in a better voltage range for the HB (.e.g, 8.4 or 9.6v), but they draw serious current (5 to 10A easy). -F (29 years ago, 5-Feb-96, to lugnet.robotics.handyboard)

  driving 3v motors
 
(...) The best solution here is to replace the HB's 9.6v batt with a 6v one. Once you get past the L293's, you'll be giving around 4v to the motors, which should be fine. -F (29 years ago, 5-Feb-96, to lugnet.robotics.handyboard)

  Re: charger board problems
 
You could just get an adapter that is rated for a lower voltage. Try a nine volt adapter or a universal one that you can experiment with. -Fred -- This message was composed using Articulate Systems' PowerSecretary. Please forgive any sloppiness in (...)

  announcing the HB Expansion Board version 2.0!!

  Re: Sony IR decoding routine!
 
ic is very sensitive to linefeed termination in icb files. if you are runnnin on an ms-dos system, i believe it requires unix style (e.g., ctrl-j) termination, rather than ms-dos ctrl-m ctrl-j style. try removing the ctrl-m's from your copy of the (...)

  Re: Sony IR Transmission Routine
 
a wireless serial link requires surgery to IC. the HB side woudn't be bad. on the ic side you'd have to plug into the board comms routines (probably most are stashed away in a single library) and substitute your own code that deal with transmission (...)

  Re: Weird LCD problems
 
David -- Soldering d0 to +5v certainly can't help; it should be connected to the data bus (pin 9 of the 6811, pin 11 of the RAM, and pin 3 of the 'hc373). (see the cpu and mem schematic). With board power off, check continuity among these (...) (29 years ago, 22-Feb-96, to lugnet.robotics.handyboard)

  DLM for the modern age
 
Hi all, Given Kazuyoshi and other's problems with DLM, if there are any Windows programmers out there who would want to take a stab at a Windows or W'95 implemention, it would be a Good Thing.
