Went to radio smack yesterday to pick up some thinner awg wire (been using 20 awg and you saw how bulky it was in the gas station) and thumbed through their electronics selection. I was looking for a "modular" means to wire my structures (as opposed to using tape and pressing stuff with my fingers!) and came across this neat stuff: Bread Board, Perforated Board, and these clip thingies with screws for tightening wires that can be "plugged" into the bread board or soldered onto the perf board. I bought them without really having a plan... Now... to put the pieces of the puzzle together... My idea now is to solder blue clips to a small piece of the perf board and then securely attach this to the bottom of the structure (screws and/or glue). I can then have all the leads for my light bulbs screwed in the blue clips - making it easy to change them out, should I need to later on. Then have a feeder come off my "circuit board" ending with a female plug and the corresponding male plug on the layout. This way, I can interchange structures from say a permanent layout to an NTRAK module or vice versa! Anyway this got me thinking... any neat "inventions" out there that you've done in the past, or are thinking of doing on any project that you'd like to share? I'm looking for innovative ways to solve problems.
