My heated grips came in today but it may be a week or so before I can get them installed. I keep hearing that a Heat Troller is a great addition to the heated grips or heated gear in general. Since the heated grips were only $26, I have a real hard time justify $70 retail for something to control them. I also have enough electrical experience to not understand what justifies that kind of price (other than it's a motorcycle accessory and people will pay the price).
So today I was looking around trying to figure out how to build a Heat Troller myself (I was certain I wasn't the first to have this thought). I'm pretty handy with a soldering iron so I'm willing to assembly my own if it'll save me money. Here's what I found:
Schematic is about half way down the page followed by some pictures. A couple pages later he mentions the 47K ohm should be a pot, not a resistor.

Or just order something like this:

My only interest is for the heated grips but the MOSFET transistor in the first link is rated for 12A so it has room to spare (the grips are 3A on high). Aside from the obvious issues of an enclosure and weather proofing, does anyone see a major issue with these? Anyone have a better idea besides just forking over the money for a Heat Troller?
