Howdy all,
The vast majority of the threads in here are well beyond my comprehension, so please excuse my naive, and somewhat simplistic questioning.
My query relates to old automotive gauges such as Fuel and Temperature gauges, that utilise variable resistors at the earthing point, such as...
Howdy,
I'm attempting to build a Temperature Sensor for a car radiator using the LM35 from National, to feed a linear temperature/voltage signal to a Digital Panel Meter. All works well as far as I can tell except once we start getting to below zero degrees Celsius.
The LM355 puts out 10mv per...
I've come across some 24 volt 10" fluorescent units from a truck, which ran on a 24 volt electrical system. What is the best way to adapt these to a standard 12 volt auto system? Should I use some form of voltage doubler? Or can I just modify the existing internal circuitry of the fluoros...
