Greetings!
> Yes, see the FAQ for a recently added section on the battery charging
Stupid Question.. Where is this faq? Web or FTP? I also couldn't find
the file pcode_2.81.tar you mentioned last week. I will be porting IC 3.1,
but wouldn't mind doing 2.81 while waiting for the 3.1 source.

Yes, The HB nicad pack will be for the HB and the interfaces I am building.
The bot also has a 10 Amp-Hour lead-acid battery for the drive motors and
any other high-current needs. I plan to build the following interfaces..
1. Address-decoder/Data bus buffer offering enables in groups of four
addresses each.
2. Hardware PWM controls for four motors, true -100 to 100 speed controls,
and automatic shutdown if the processor resets/fails.
3. Hi-Current H-Bridges for the two drive motors, using the circuits
described in handyboardmail.txt (Thanks, everyone!)
4. A sound board, mixing inputs from the HB-Audio, an external walkman-jack
(for FM radio-linked audio from the host computer), and a SPO-256 speech
chip, for (rough) english speech. The mixer feeds a small amp and speaker.
I doubt my boards will be as space-efficient as the HB itself, but in my
bot there is room, so I will just keep building...
In other news.. the base, motors, gears, and quad encoders should be
finished within hours.. The parts for the H-Bridge should arrive Monday.
A childhood dream is finally coming to fruition.. Thank you to all!

| (...) The FAQ is linked from the main HB web page under the title "the Handy Board FAQ", or directly at: (URL) pcode source is at ftp://cher.media.mit...dist.tar.Z and also (URL) should fix that last link, because you'd never find it unless you knew (...)
