Alternative to Soldering

This video shows an alternative to soldering small components like the 0603 or 0402 SMD LED.  You see wire glue (a graphite substance) used to make contact between electronic parts.  Wire glue can be used for any low voltage connection, not just LEDs. Wire glue has a place in my tool box because sometimes you need a connection without the heat of a soldering iron.  Try it.  Wire gluing takes extra time because you have to basically tape parts into position, add the glue, and then wait for the glue to dry. 

Modeling Railroad Signals

Well, here it is after much ado!  Making railroad signals was not difficult.  The big trouble is having to order all the parts to do the job.  And the prices were not bad.  I had to buy 402 LEDs from china, magnetic wire and wire glue.  All toll, about 20 dollars US.  Now there are plenty of other things that make the job easier, like a pc and printer to design and print out the pattern, paper, paper-clips, plastic, scissors, glue, tweezers, wire cutters, markers, resistors,.... but all these things I had on-hand; and I don't included in actual cost because much of them are used doing other chores.
In any event, I am happy with the results.  That was 8 mast with 16 back-to-back, 2 aspect signal heads,  having 32 red/green 402 LED's.  The look is nice!  I held off on signals till most of the diorama was complete and I'm glad.  The look of them is simple yet they fit the overall mood of the diorama.

Wire Glue Really Works!

The above video is in reponse to reviewers of wire glue that said the stuff does not work.  It does work and my video proves it.

I found myself trying to solder tiny 0402 LEDs in-place on plastic.  The 402's are so small I needed a magnifying glass just to see the nodes.  Problem was the heat from the iron was mis-forming the plastic the LED's were set in.  I needed something without heat... I needed wire glue?!

A quick google search turned up wire glue... a greenish-black graphite based soupy liquid.  I wasn't sure if it really worked.  I read as many reviews on wire glue as I could find.  I few users said they had success with it, but there were also the bellowers... the ones thay cried how they bought it and it just did not work, or that it was not glue at all and their wirng fell apart.  Like anything else, you just have to try it for yourself.  So I bought some "Wire Glue" in a small bottle from on-line and also bought some in a tube from Radio Shack.

Fact is... both brands worked for me.  The Radio Shack brand was a little soupier/watery that the Wire Glue brand; and I like the ability to open the Wire Glue bottle and stir the glue as opposed to the tiny Radio Shack tube.   I followed the directions, used small dots of it to make connections on low voltage electronics and honestly I was overjoyed at how well the stuff worked.  I never had a connection fail.   The big plus was that the product saved my electronic project.  Oh there is a few extra steps like taping wires in-place until the wire glue dries.  But honestly, I was happy I did not have to fight a HOT soldering iron to connect wires to 32 tiny 402 LED's. Oh and FYI, some folks said the wire glue crumbled after it dried, but I found the stuff to be rock hard and difficult to scrape away with a hobby knife.  If I had to remove a wire after the glue dried then the 38 guage wire broke before the glue gave-way.  Plus, if the idiots would just read the makers suggestion of using epoxy over the wire glue joint, then the joint will hold till after they are dead and buried.
