Hello people
My knowledge of electronics is... well, barley existent.
I have a battery, So, if I know anything about electronics, It means DC, which makes my life easier.
In the schematics for a constant current source with NPN BJT, I'm pretty sure there's ground, but with a battery-powered device, I don't expect I'll be connected to the ground...
So I can understand only very little of the designs I see
Here's what I got: A battery, some resistors, 2 NPN BJTs, and 2 electrodes which will be in things with different resistances.
Can I use these stuff to make sure a constant current will pass through whatever will be between the electrodes?
I don't need to know the math if it's complicated, i'll figure it out. I just want to know if it's possible, and if it is, how will it look
(Many years ago, I saw this website, and then I lost it, and now I've found it again, but there's collage - and I don't have the time to study all this stuff, I have to wait for a vacation... but I want to know now if I should even try to figure it out or just buy a voltage regulator. don't want to wait too long for it to arrive...).
Thank you very much!
