I built the circuit as shown and when i use a 6v 60mA bulb it lights to full brightness instantly, when i change the bulb to a 6v 160mA it glows faintly and takes almost 30 seconds to reach full brightness....can someone shine some light on this for me please (pun intended) lol
Hello, I'm a noob at electronics so hopefully you guys can help me out;
I'm trying to make a circuit that uses a transistor as a switch to a fan, the idea is to have a thermistor connected to the base of the transistor while the collector and the emitter to turn on a 5V fan when the thermistor...
this is the schematic ive built. Its designed to give an adjustable output of 35-50v, the question is which part do i have to change to make it work below 35v. I have this connected to a 24v transformer and all it gives out is 35v(no matter the pot position). I know this is very simple for some.
