Infrared Remote Control

Greetings everyone,

I am constructing this circuit as a hobby and I needed some guidance. I found a simple circuit in https://home.maine.rr.com/randylinscott/aug98.htm

Firstly, I wanted to know whether this circuit will work as I do not want to waste money on a circuit that doesnt work well.

2. I have some problems reading this circuit. Where will the output of NAND gate B,C and D connected to?

3. I am using a 240V AC as my mains supply. Therefore I need to modify the circuit of the second diagram. But I do not know how to modify it. Kindly please help me to design a suitable circuit for it.

Any help wold be greatly appreciately.

2. B, C, D, gates unused and for lower power consumption the inputs connected to GND.
3. No need circuit modification, just apply a trafo with 230V primary and min. 600V triac.

What is MOC 2010? Where can I find information on MOC 2010?

It's an optocoupler with triac output. Any type good for this application e.g. MOC 3021, or MOC3041 with zerocross switch.
