Need some help choosing wire for a project Answered

I'm making this https://www.youtube.com/watch?v=jLia59KfkSw

It says to get magnet wire and 12 gauge paired AWG wire.  Home depot said they didn't have it.  Can I reuse any wire from lamps that I plan to get rid of?

I found magnet wire on ebay but which one do I choose?  

http://www.ebay.com/sch/i.html?_odkw=12+awg+paired+wire&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xmagnet+wire+enameled.TRS0&_nkw=magnet+wire+enameled&_sacat=0

Is this the 12 AWG wire? http://www.ebay.com/itm/10-feet-12-AWG-Twisted-Pair-Silver-Plated-Cable-speaker-wire-37-strands-/381386615431?hash=item58cc69ea87:g:AHwAAOSw0JpV6JGw

or this?

Thank you, Josehf, for your piece on Magnetic Wire. I have stripped some cord and now have the wire that I need.

But I think I made a mistake on the LED light strips (see image). The video said the cut at the copper intervals which I did. But the solder points in the video are at the silver connection points (see orange circle).

Can I solder the wire to the copper point? (red circle) Or do I need to cut and rejoin the strips so the silver points are at the end?

Next time click on the reply box so I get a message you have said something to me.

Anyway your cut looks good you can solder at the copper red circle.

The joints in the orange circle are done in the factory, although they sell it in a continuous strip they make it in pieces of 10 groups of 3 LEDs and then solder the groups together to make a continuous strip.

Does not motter at all as long as you connect all strips correctly.
A neat way of doing this for flat things is to use copper tape in 3mm wide.
Half way over the contacts and then solder, works like a treat and keeps everthing very clean.
And one of the best sources for magnet wire is old transformers like microwaves for the thicker ones and old style wall warts for the thinner gauges.
If you need really thin go for the motor that spins the plate in the microwave - hair thin...

I go to the thrift store on Saturday (1/2 price day) and get a transformer (charger)

Disassembly is sometimes easier with an angle grinder + cutoff blade, but one can also hammer the "E" cross section laminated core in order to get it to unglue. Then you've got lotsa cheap magnet wire.

Somewhere in these forums, I made an electromagnet from a transformer. there had been dissent about whether transformers were electromagnetic. Lifted 15 lb. I should probably turn that into an -ible someday. If anyone can find that thread, maybe I will instructablize it.

Most lamp cord is 14 or 16 AWG and that should do for 10 amps but if it worries you just double up the wire. The wire you found on Ebay will do I suggest the cheapest.

Almost any scrap wire should work for the magnetic wire as long as it is around 20 AWG.

The 20 AWG magnetic wire should do you I get my magnetic wire this way.

Thank you. I've looked at Lowes, Home Depot, Harbor Freight, Hobby Lobby, and two electrical supply stores. None of them have magnet wire or enameled wire. The closest thing I found was carbon mig welding wire.

Will that work?

You should be able to reuse the lamp cord you have as the hookup wire and power rails. You would have to go through the trouble of stripping the ends or an entire length. If stranded, twist and tin the ends with solder to make it easy. It may be a little awkward to solder to the pads because it is thicker than magnet wire so double check it doesn't contact the other pads. Good luck.

I failed to mention this is an Instructable https://www.instructables.com/id/How-to-make-a-super-bright-LED-light-panel-for-vid/
