I like it
I think he did good, I think the video was great, clear and I know punchboard never looks pretty. This DC to DC converter, I think is the best, Thank you.

A real DIY video.
Thank you for sharing.

BTW, some LEDs can be lighted up by one 1.5V battery!

  please check connections again.. I made more than a dozen for the friends without any difficulty.. as you see ferrite core is simple and easy to make without any specialty.. at least try MW broadcast radio ferrite antenna bar..

ferrite core?
is the ferrite core acting as a transformer which is regulated by the transistors?

- ferrite core
  ferrite core generates electric pulses..
  in fact this circuit is square wave oscillator.. when transistor switches off causes reverse voltage to induce in the coil.. and these continuous voltage spikes light led.. LED is reverse biased according to the battery.. that means no direct battery current flows through
  the led..
  regards

- 1n5K630
  1n5K630 is a capacitor.. that means condansator.. value is 1.5 nf.. 1.5 nanofarad.. or 1500 pf.. or 0.0015 mf..
  pf picofarad.. mf microfarad.. all same..
  630 is breakdown voltage.. not so important.. try what you find..
  regards..
