Subject: [alt-beam] I built a glide bot, Kinda


Ok, long story but I ended up with a bunch of dry ice to play with. So for
fun I was playing with it in my RJP, when something happened.
One of my bivores bumped the dry ice, and the ice slide off. Then I
remembered, due to the fast degree of "melting" dry ice levitates. Bivore,
plus dry ice equals Glide bot.

I took a 1381 SE, added a model airplane prop I had, pegged the contraption
to a block of ice, fiddled with it to get it to sit right, and it has become
the most bloodthirsty bot in my RJP. So far it has snapped the motors off of
two of my photopopers (just nudged them out of the fuse clip) and has pined
all my Symets to the wall.

Are there any rules about dry ice, for the robot games?
Albeit it only lasts for about 2 hr. before I have to replace the ice, I
want to see it go up against a turbot and a Mini-ball or two.

And has anyone done this? Or might I take credit for the Ice bot?


Sincerely,
Jim Cook

I have a few questions about these. I bought one surplus just to mess with.
They come apart easily and look like a durable PCB.

But, does anybody know (A) Where the transmitter crystals are? Are they the
silver button thing? Or the diode looking things?

And how might I find what frequency they transmit on?

I take it by this that you have some R/C transmitters... The crystals are
like caps in size and kinda shape but usually are oval cans and NOT soldered
to the board... are they proportional (driven by potentiometers) or just
switches??? what kind of car would they drive??? As to the frequency... find
a oscilloscope and see... Or you could take it to your local ham radio
operator...

There's usually only one, and it's silver. On most transmitters you can
take out the crystals and replace them with another (close) frequency - that
is if the unit is reasonably expensive. The cheap 2 channel
non-proportional radios simply solder the crystal in so you can never
replace it. But then it's intended not to be opened anyway. These usually
operate with switches instead of pots (That's why they're non-proportional).

Look at the crystal. It usually has the frequency written on it. My Futaba
4-channel proportional transmitter crystal has 29.825 written on it, so it
operates at 29.825 MHz. in Australia there are two bands that you can
transmit on for this purpose - 29 MHz and 27 MHz (CB radio).

Hello all!

Wilf brought up something interesting the other day and IMHO is warrants di=
scourse: Photovore Flocking. =


Migrating geese use a kind of location sound when flying in formation. AFA=
IK, it's just an "I'm here!" kind of thing. It should be relatively easy t=
o build this kind of thing into a fairly un-complicated Photovore. My thin=
king is that there has to be a good BEAMish solution. =


There needs to be a number of systems to the Herd PhotoVore (HPV). =


1. Battery Power with solar charging capabilities!
2. Auditory sensors (for positive audiotropism)
3. Vocalization
4. Locomotion ('natch)
5. Vision (for positive phototropism)
6. Collision avoidance (feelers) =


What I'm proposing that we do is to work on a joint project. It's working =
quite well on the Soccer Project and the PSH Project. =


I feel that we need to push BEAM Tek forward. There is a vast pool of know=
ledge and creativity to draw from out there, so lets get off our collective=
duffs and take our hobby to a useful level!
