Another alternative could be a technique I have seen used in some old
radio designs. The attached gif shows the general idea. You create
such pads with all the possible connections brought opposite each
other. Then it's very easy to bridge the required path with a solder
bridge (keep the gaps small enough). These are also easy to open again
by using a soldering iron & an old tooth brush (melt & brush off - being
careful to brush it away from you & other important things). Sometimes
they open up with surface tension itself when you touch the bridge.

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" :)

solarengines. Most other BEAM websites have circuits pages too.

responding to the discussion about cutting & resoldering tracks and the
non availability of desoldering pumps with some BEAMers.

or that knows where to get supplies in the area?

Usualy, it breaks the tension between the blob and separates it. Works well!

9382 Thu, 20 Jan 2000 10:32:55 +1100 [alt-beam] Re: powersmart head beam@sgiblab.sgi.com Elmo All the PSH circuit to date still have problems. Wilfs Version 2 (is is
that version 2A) circuit with the extra LEDs seems the bext (but i
haven't built it). I have a very simplified version of Wilfs circuit
1x74HC240 and only 2xResistors and 2xCapacitors. I am still debugging
the circuit but it looks like it will be a rather stable and
reproducable version.....just gimme a couple more days to finalise my
design. Tutorial and circuit explanation coming soon.....
Sparky managed to get the original circuit from Darrell Johnson going.
