[lgtngstk] was tired of driving his cold Honda Civic to work. He built an instant on electric heater for his car from a toaster and an ATX power supply. The toaster elements were mounted to one half of the case, while the fan was left in it’s stock location.To get the fan blowing hard enough, he whipped up a DC voltage doubling circuit. To finish it out, he added relay control and plenty of new holes in the case.
