Re: Raduino transistor getting hot

That's what I ALWAYS do apart from fixing then to the case or a heatsink. Regards Lawrence

fit a heatsink! (Was the first thing i did to my Raduino!)
I've also heard that one can regulate voltage in two stages to spread the heat between two regulators. For instance, from 12 to 6V by first using a 7809 regulator followed by a 7806. Theoretically, I guess, the same amount of heat would be wasted, but only half as much in each device. A heat sink *might* be the simplest solution, unless you don't have one but you *do* have the two regulators. 73, Todd K7TFC
