More tinkering around with Buck Boost Converters - and some ranting.

SCHEMATICS ARE AT 3:02 17:19 17:59 19:04 & 21:35. 
This is mainly just experimenting and not intended as a tutorial.

I thought it was about time I did a follow up to my home-brew buck boost circuit adventure. Also I reverse engineer a proper pre-made circuit and make my own, and finally I rant about one annoying "feature" my camera has.

I know this video is kinda all over the place, but it was shot over several days, I took about 20 takes re-recording where I mess up in my speech and Ill be dammed if I'm going to re-record any of that again!

Schematics:

3:02 The first incarnation of my own buck-boost converter
17:19 "Reverse Engineered" Chinese buck-boost converter
17:59 The actual schematic of the buck-boost converter
19:04 TL494 as variable PWM oscillator
21:35 My version of the Chinese buck-boost converter (WIP)

So, there, now you can't say I don't post the schematics, just take a screenshot from the video if you want them, that's what the "print screen" button on your keyboard is for, you can then paste that into paint or whatever.

The quality of the videos will get better from here, with better camera angles, editing and such. This will be the last that's "all over the place"
