Subject: [alt-beam] Re: Pertaining to the Hextile things. You should really make them


That's a fair design, with the cables!

Wow... I thought you realy only wanted one board, and the DIP in the
hextile, and cutting it out was simply a way to get the DIP while still
pleasing the majority and giving them hextiles. I had though of a
hextile with a socket that would accept the DIP. Never once thought
though that it could be the idea you wanted! That's even better, caus
ehte DIp can be used on Breadboards, custom PCBs, and then still be able
to go back to the hextile board. That's practicaly perfect! I thought
you wanted only one board and that it would be a choice, hextiles being
the winner. If this is all true, then I can be very happy with it!

I sure hope we are both thinking the same thing here! Haha! Had I only
known! :)

You could have the hextiles (tritiles?) aranged in straight lines, and
then the DIP portion along side the thing (I assume you'd have them
manufactured in sheets, much like hextiles usualy are. I'm looking
forward to these things!

As for desoldering, not everyone has a desoldering tool. I know, they
are cheap, but still. You could have the 5 configuration points and then
just solder in what you want. No default. That'd be reasonable too. The
hextile might be shrunken down too if the DIP plugs into it, as some
wiring beteen neuron and hextile contacts can exist in the center of the
DIP area, since the DIP nolonger actualy takes that area. It'd sure be nice!

They're far from useless - just take a very long time to charge, that's
all. They're a great quality cap.


>What about the motor? Would that be any good for BEAM app's?

They el-sucko.....

9373 Wed, 19 Jan 2000 14:05:50 -0600 [alt-beam] Score: BEAM Roboticist 3 - Model Railroader 0 "beam@sgiblab.sgi.com" Kelly Petriew Hi Lads,
I realize the questions I'm about to ask have probably been flogged to
death, but how much current does one of those Namiki pager motors draw?
Their website has virtually no specification information.
http://www.namiki.co.jp/guide-e.htm

I was also browsing around the world to see what I could learn about
different ICs and how they might be useful in BEAM. Lo and behold, I
discovered the BA6212 on Rohms site here:
http://www.rohm.com/products/databook/standard/pdf/ba6212.pdf
In brief, its a 20pin DIP that has 8 internal circuits and a strobe pin,
can run up to 400ma loads, inputs can directly connect to CMOS, not sure
about internal resistance. The main application is for driving LEDs,
motors, or relays.
This part may be hard to come by as Digikey and Future-Active do not
have them (haven't searched much further)

I'm not great with how electrical parts work together (I'm relearning
and have basic knowledge).
Am I barking up a dead tree here?

About my subject line --> I called around today to all the (5) pager
companies here in Saskatoon, and only one actually did repairs inhouse..
the rest all sent them away (bummer). Anyway, the only service guy I
talked to was super nice and offered to go thru his junk box and
retrieve a few pager motors for me. I got 3, the model railroading guy
he considered giving them to didn't get any, muahhahah! WOW, I just got
off the phone with him and he is willing to order me some at his cost
(dancing a jig).. so I'm ordering 20. I will not disclose how much they
are (to protect the interest of others), but lets just say that I
"lucked out" :)
