  1. How to stop 555 IC from heating up?

    I was trying to make a LED flasher with 555 IC. Then I thought how about I set a transformer with the output-ground pins. And I also reduced the resistance between 7 and 6 pin. And I am getting a 31V AC output from my transformer output panel. Looks like it is possible to make an inverter with...

    hey guys, I hope all is well. I have a question about the following two schematics. One is a high power IR transmitter and the other is a long range ir transmitter. When I look at them both I feel like they're doing the same thing just in a different way. Would I be correct to assume that they...
