Found another alternative

Not sure how it works, if its just a resister or PWM but at that price if you are looking for cheap then this looks like it.

Thats about what I set my controller, Full on or just over half.

i really should have made one of these years ago. There was a slight frost this morning when I left home but an hour later I arrived at work toasty. Wasn't so keen on the stretch of sheet ice with a car in the ditch just down the road from work though

I bought one of the motor controllers Endo linked above, which I picked up from the post office this morning, so a bit more tinkering is due this weekend. Still not decided if I should stick with the potentiometer or go for a High-Low-Off switch.

Continuous for the win. More options; simple to adjust; more cool electric gadgets on your bike!

Harder to control with winter gloves on though,

I suppose, but never given me any trouble. Non issue for me.

I reckon it should be pretty easy to build a controller, I just need to find someone with more electronics knowledge than me to point me in the right direction, you can get off the shelf timer chips that can produce the signal easily enough but it then needs some amplification to get it up to 5A

Just off the top of my head. What about a dimmer switch from a house light.... or a volume switch from a PA/Radio system or a slider rahter than a twisty knob.......

I am thinking about making an arduino controlled multiple channel pwm controller for just this sort of thing (infinite adjustability on temperature/brightness for bike appliances up to around 50 watts. Maybe four channels? I am in the process of getting ready for the cold winter here, and I am planning to commute for as much of the winter as possible on the bike. I am going to do heated grips/probably some kind of homebrew heated jacket. As electronics are one of my hobbies I am going to throw together a pcb and probably get a few of them made.

Would there be any interest on here for one? If I get one pcb made, I could just as easily get ten made. PM me if interested.

Hmmm, I see a potential new project coming up

The tape's quite a lot more expensive than using wire (about £6/meter), but a lot more flexible.
