TSOP and 555-timer circuit to turn on LED with IR remote control

[runjoh]

Hi!
I was browsing youtube and stumbeld across this video of a circuit with a TSOP and a 555-timer that turned on a LED with a IR remote control. This is the video:

I was interested to try it out and it worked perfectly! The problem I have is that i don't understand how it works and the creator of the video does not explain it. I would like to know how and why this circuit works.
I have also uploaded the circuit schematics I made (sorry if it's bad).
Thanks!

Look up bistable 555.

Look up bistable 555.

What about the rest of the circuit?

Didn't look for too long as it is drawn in an unconventional manner and difficult to see what goes where.
Only resolve would be to look upo spec sheet on the IR and redraw circuit correctly and go from there....busy today.

Ok, i'll try my best! Thanks

The video has no parts list (which of the many TSOP ICs is used or which one is available in India?). It also has no schematic.
It will probably work with a TSOP1738 (look at its datasheet) and there are many circuits on the web that explain about an LM555 used as a set-reset latch. Do you know how transistors work? Do you know how to carry solder around on the dirty tip of a soldering iron like that guy in India?
