Temporary Announcement:
Because my daily and monthly schedule(s) are becoming hectic, I may not post to these threads for an indefinite period of time. I can occasionally take time on some borrowed computers to post Replies here and elsewhere. I do have an active thread that I started on OU.com that requires a lot less time than the preparation this Forum does. However, I realize that that site isn't this site, obviously.
I can take less time and spend no money to do my usual research with other electronic engineering subjects.
ANNOUNCED GUIDELINES:
This particular thread topic will concern itself with helpful hints in general with respect to electronic research/engineering in potentially wide spectrum applications.
Problems encountered in research and questions about research would also be acceptable.
This thread is, as are all others, open to the public.
Additionally, it will "stick" to the top of the page permanently as an archival topic for all to see.

Because I live in a high-rise apartment in which the management would probably frown upon my soldering circuits together and also smelling up the hall, even with the window open and bathroom fan going, conductive glue can function as an adequate substitute.
Take a look at these:

I'll begin testing this method of constructing prototypes with components I have now, since I get paid shortly. Updates can follow with tested results of finished, demonstratively competent components and their attributes.
As a variation of the Update page cited above: I'll start with experimentation of glued electrical connections by:
1) Beginning with 2 wires twisted together...
2) Spread white Elmer's school glue on the bare twisted connection...
3) Dip that wet, gooey connection in a small pile of graphite or a graphite/metallic mixture...
4) Let set and cure to hardness...
5) Test connection with VOM...
6) Repeat steps 1,2,3 id the resistance is considered too high or the connection lacks continuity...
7) Optional: Cover the finished connection with a protective layer of heat-shrink tube.

Reedit: 5 Jul '11: Added the 7-step Variations and spell-checked the whole text. Added my 'Signature text and updated my 'Profile.'
Interesting idea and product.
Did you measure the resistivity?

I just borrowed an
analog Radio Shack 17-range multimeter indefinitely from an acquaintance. And I also went out and bought some of the necessary supplies: "steel" reinforced epoxy glue(resistance=30 giga-ohms
(!), regular epoxy glue, white school glue---and for a metallic resistance-reducing source, a cut-up aluminum pie plate(
really small pieces).
I can also use really short multi-strand twisted copper or steel wire of a small gauge that's been wire-cut to about 1/64". (Available at a local hardware store.)
For graphite, I'll go cheap and burn either paper book matches to carbon ashes, or do the same with wooden strike-anywhere matches. (This stuff won't be pure graphite, but it's cheap enough (read: pennies) to be good for a starter prototype material.
Will try and get started next week after the Fourth.
