Everything but the Teflon wire, clothing material, and needle can be purchased from radioshack. All together the materials cost me about 50 dollars, and you'll have enough wire left over to make a jacket and more.
- 30ft of 30 AWG Teflon wire
- Some normal copper wiring (16 AWG)
- Connectors (See note 1)
- Ring connectors for connecting to the battery (See note 2)
- Fuse (Over 4 amps with just pants, over 10 if you make a jacket)
- Fuse holder (See note 2)
- An SPST switch (optional but recommended) (see note 3)
- Thermal underwear (or whatever you want to use)
- Cloth to make a lining
- A thick sewing needle
Note 1: You'll want to chose a connector that can be can be quickly disconnected. This is for the cases where you forget to disconnect from the bike and you try to walk away. Rather than tearing anything apart, the connectors will just come apart. There is an instructable on how to make one that's pretty cool. Here's the link: http://www.instructables.com/id/ThinkSafe%3a-A-Magnetic-Power-Connector-for-Thinkpad/
. But if you don't want to make one, you should get a coax type plug or maybe a quarter inch plug, like the ones used on guitars. The coax plugs are what is used on professional clothing. I have a bunch of bullet
connectors laying around, so that is what I'm going to use.
Note 2: You can buy a pre-made battery harness with fuse holder for pretty cheap. It's actually cheaper to buy the pre-assembled one than it is to make one unless you have the parts laying around. This second time around I'm using a pre-made one. http://cozywinters.com/shop/wg-dcjk15amp.html
Note 3: You can also buy a pre-made switch which looks pretty nice and is waterproof. This is what I'm using this second time around: http://cozywinters.com/shop/wg-oocoax.html
