NE555, LM7805, and MC34063

[Michael Harem Raymundo]

Hello.
I'm looking for a replacement for these ICs because we need to submit a project proposal tomorrow, July 26, on our Electronics 1. However, we're not allowed to use any integrated circuits. I'm planning on making a project that does a wireless energy transfer. Thanks,

The 7805 can probably be replaced by a zener, a resistor, and a transistor.

The 555 can be used to do so many things that weed have to see the circuit to comment.

The 34063 is a switchmode regulator? Again, show us the circuit and consider whether you can use a linear regulator.

Mind you, because this is homework, weed probably ask you to do most of the work. And since you've left it so late...

Bushtech, that doesn't look quite right. The three resistors go from Vcc to gnd.

I just pulled an image from the net to show him what he's up against if he needs to build an analog version by tomorrow

but, yes, the bottom leg should go to trig. not earth, well spotted and 0/10 for circuitstoday

Building a discrete-parts equivalent of the MC34063 will be an even greater challenge than the 555!

I thought I'd break it gently

You should not need any of those for wireless energy transfer. You basically need an oscillator, an amplifier, and a coil fot the transmitter, and a coil, capacitor, and diode for the receiver.
