"of course not, it's my life". Well, u ain't alone my friend. 2 weeks into electronics, loving it(also sometimes hating it). I just have a single breadboard, no more circuit real estate, ordered a few more. So i can glue'em together and a make a bigger playground. Thank you for the video.
I was wondering why all youtube videos showing this circuit only use bipolar transistors, why not use mosfets or igbts, or is there a reason why they cannot be used?
I just googled it and found several circuit diagrams of this circuit using mosfets, and there's really no fundamental reason you couldn't. I assume it's just because you'd only ever make this circuit if you're learning, and you would learn BJTs before you learn MOSFETs and BJTs are easier and more plentiful (generally speaking) and extremely hardy.
@@simplyput2796 Thank you for your reply. I rarely buy transistors new because there is so much electronic scrap to get transistors from. I.G.B.Ts are so easy to get from power electronics and have high current and voltage ratings. I plan to use I.G.B.Ts in this circuit.
I made a astable mutivibrator using two GT60N321 transistors and instead of using two leds I used two 50w halogen down lights. It works well but has a strange side effect. I put a variable resistor to change the flash rate but when I turn it clockwise to drop the resistance the flash rate decreases, the flash rate should increase so why does it do that?
Hook up a multimeter and make sure the resistance is actually changing the way you expect, because you can have it decrease clockwise or anticlockwise depending on which two pins you use. Other than that, I'd have to see what your circuit is to figure out what's happening.
@@simplyput2796 I connected positive to the lefthand pin and the center pin goes to the resistor. I have since connected the multivibrator to a transformer and use it as a inverter, also I now change the frequency by changing the capacitor instead of using a variable resistor.

Thank you for the video.
You know what, I've always wanted a GHz oscillator. Now I am thinking to use this schematic to make one.
Excellent explanation ! Keep up the great work dude!
Thanks
Very clear explanation. Again Beautifully put. Please also make video(s) about OP-AMPs. Thanks
Yep, I'll be going through all kinds of amplifiers and comparators as time goes on. But it'll take a while, because there are a lot of them!
