So I shouldn't be left to wander stores alone...
Back in the automotive section at wal mart they had these electrically heated coffee mugs for sale $3. Well, that's interesting, and at that price worth the risk to buy and gut them. I knew there had to be some sort of resistor wire or something in there to heat it up. So I bought two of them.
Here's what I got.
First of all I took apart the cig adapter to make sure there wasn't any weird power supply going on in there. Nothing more than an LED and resistor to show it's powered up. So it's getting the full 12vdc.
Tried to pry the plastic liner out. But resorted to just breaking it off. a pair of pliers made quick work out of them.
I cut the leads off in the cup. Dunno what to do with the stainless steel now.. Guess I'll use it in the shop to hold bolts or something.
The wire is held in place on the liner with tape. Just pulled it off and the wire comes right off.
Here's the resistor wire. There's a temp switch on the base. I'm not going to use it.
A pic of all the bits.
I'm going to take my grips off. I just put the cushy foam ones on. I'm going to put some of the alum tape on the tubes to reflect the heat. Then wrap the wire on the tubes. Then cover with tape like they had. I'll leave an extra loop of wire coming off the throttle tube to help. Then reinstall the grips. To control it. I'm going to put a three way switch. One will be a full 12V, the other will hit a resistor block, then the heater wire. That'll give me a high and low. I'll even use the two LEDs to show me that the system is "on". Heated grips for $10...
