Subject: [alt-beam] Re: The 240 microcore - was Bicore question
Oh, okay, right! I know the physical differences, but what are the cons
of a suspended bicore verses a normal bicore?

9738 Thu, 03 Feb 2000 10:43:24 -0500 [alt-beam] How about a starter pack? Beam "Sathe Dilip" Like the hextiles being discussed, I think someone should create a PCB
design with individual segments being what is useful for a newbie who
wants to start his hobby in a step-by-step manner. This set could
include things like:
One each of different solar engine types (FLED, 1381,...)
A photovore
Two motor walker
2 DOF head
more?
The designs could be generic enough to allow for usage of parts that the
experimenter has at hand. If something like this is available, new
BEAMers will have a definite place to start & grow their knowledge.
What do you all think?
(Borrowing from Dave's description of Solarbotic's Hextiles, the starter
pack also can be designed with "partially routed out so you can snap
them apart, or leave them
together." "with solder mask and component mask labelling for easy
assembly")

A conclusion is the place where you got tired of thinking.

Not too long ago I designed a BEAM prototyping board onwhich you could make a bicore, reverser, photovoric head, bicore walker (two bicores) and a few other bocore related circuits. It requied about 5 jumpers for some circuits, or about 1 or 2 for others. I never made any though and didn't test them, and unfortunately I'm not sure if I have the drawing anymore, but is that kinda what you had in mind? I also designed H-Bridge pcbs which can easily be attached with solder bridges to the "Multi-Boards".

This is like the ones I designed. You could also replace the 74xx240 with a 74xx14 and make a microcore, or use the individual 'nvs'

9740 Thu, 3 Feb 2000 15:11:07 -0500 [alt-beam] Mind controll: Eh, not really. "Dennison Bertram" Well, I finnaly wired up the circuit I described a little while ago for
'mind control' experiments. The results? Well, you certianlly can act as a
resister element in your circuit if you want. And various things can and do
change your acutal resistance, but the skins resistance is in the megaohm
range makeing it very difficult to distinquish between changed in
resistance in the skin with a bicore type cicuit as you don't have a 'tone'
persay, but rather just clicks. So, I guess that idea doesn't work out.
