Subject: [alt-beam] How do I make a Remote Controled bot?
I want to make a bot that can be controlled by a RC. How would I find a schematic for the transmitter and receiver? Thanks for the help.

reciever module/remote transmitter set.
If you want to use digital control, there is a wireless transmitter
reciever pair that works with the Basic Stamp or other microcontrolers
and computers. If you have a Bassic stamp at each end, you can make a
nice program to control it and have them comunicate wirelessly.
If you want to have push button control, you can get real creative. Old
style touch tone phones have a removable keypad. You can also buy
decoder chips or even a decoder that works with the basic stamp that
understands the different tones generated by the keypad. You can create
a digital microcontroler, discrete components, wire signals straight to
the motors, or whatever works for you. Though most phones only have 12
main keys, DTMF touchtone supports 16 buttons. if it doesn't have it,
you can sometimes add that last row. The buttons simply form a grid. If
you get lucky, you might find one with A B C and D (or other labeled)
buttons next to the numbers. If you ever needed more than 12 or 16
functions, you can get another DTMF touhtone encoder and decoder board.
Pull the crystals out and get new crystals, both EXACTLY the same
percentage of frequency increase over the old ones. If you were adding
one extra DTMF board (in addition to the original board), you would
double the frequency. If you were adding three, then double frequency
for one and triple for the next. You can transmit the sound over a
modified cordless phone or even walkie-talkies.
Last method I can think of would be to scratch build a transmitter and
reciever and come up with a format for the transmited signal.
I personaly plan to use the DTMF method on my future Quadrapod.
Good luck!

8041 Sun, 28 Nov 1999 19:56:43 -0800 (PST) [alt-beam] Type 3 Solar Enging beam@sgiblab.sgi.com Daniel Grace I have read on several BEAM sites that there is no
type 3 solar engine. I was wondering if anyone has
_attempted_ to make one. I have a design that I made
for one, which probably won't work, knowing me. I
don't have the parts on hand to test it. I was
wondering if anyone has attempted to solve the problem
the way I am trying to. Reply any way you like, but I
would like to hear from anyone who has attempted to
make an SE3.

8042 Sun, 28 Nov 1999 20:02:23 -0800 [alt-beam] LED Ramp beam@sgiblab.sgi.com Greg Powell I have found another circuit that could apply to nocternal beam bots. It fades
two LEDs on and off. It only draws an average of 5mA and is looks very
impressive. I have already designed a PCB for it, if anyone is interested
they can find details on my page.
Cheers,
Greg
