Скачать или смотреть Arduino 20w LED strobe with MOSFET - How to

** UPDATE **
You don't need the additional voltage regulator because the Digispark can handle 7-35v on the VIN pin. I originally built it for an Arduino Pro Mini which isn't so tolerant to voltage input.

Here it is!
Please bear in mind that I'm crap at instructional videos and this is only a guide on how to build them.
If anyone has any problems following the instructions, I'll do a schematic.

Any LED will be ok as long as it's tolerant to the voltage you're supplying.
