Just a spontaneous experiment in making a tree shaped ornament from solid copper wire shaped and soldered together with a Molex style LED holder on the end of each branch.
The core of the tree is the negative rail of a 5V supply and a single wire goes to each LED with a 220 ohm resistor in series at the base.

I'm doing something similar! Sculpting a stick-man from a mains conductor, and he'll be the common ground for some LEDs strung like fairy lights, as well as a microcontroller to flash them in complex patterns. It's really tricky getting those joints together!
I made a LED tree and I had this idea you sugest using the tree structure as groung but was afraid haha.. to many cances to have a short. So I end up making the whole circuit and covered with cold porcelain.. it was a pain in the@ss
im actually doing the same thing in my robotics class but im going to program the lights on the tree with a circuitboard under the roots and as far as i know im the first person to ever do this
can you do a video showing how you did it? ineed 5 lights ive looked online your vid is the only one ive found atlease talking about!
what if you use the bare 2,5 mil copper as a base and negative lead like you already do and use enameled wire wrapped around the bare copper as a positive lead
lots of work, but that should give your tree a really nice optical coppery effect
Very cool idea, something like this would make a great decoration. But I really hope you're not inhaling those lead fumes!
That is quite cool!!!
63Sn37Pb alloy would be the stuff to use for this as it is a eutectic alloy. The lower melting point also helps a bit.
Probably it's the truly eutectic solder that sets nice and smooth.
Solder with slightly different compositions (like, as an extreme, plumbers solder) will go into a mush just before entirely solidifying.
keep up the good work..just about seen all your vids now lol
I expect to see kits of these in your store soon. 😉
I may adapt this (using 3 way connectors?) to a series wiring arrangement using solid cat5 cores.
I have a 50v DC bus in the workshop (mostly dealing in telecomms) so series would be ideal!
Yep, the top of the tree looks much better, that bottom one looked more like the old style TV aerial after a storm 😀
I used to make trees out of old telephone cable up to '300 triple' (900 cores) back in the 70's, shame we didn't have readily available leds.
