Hand generator step up boost powered ATTiny85 Start sketch (Arduino Blink)

It is possible to directly power ATTiny85 [3] (power LED lights up). But any minimal slow down in turning the hand power generator [1] crank handle immediately resets the ATTiny85. I was never able to pass the initial 5s pause before sketch begins to run. I remembered step up boost converter [2] and gave it a try. As you can see I passed the 5s phase and the 2nd LED got lit, but then I was not quick enough and the ATTiny85 did reset. But after that and after another 5s pause the 2nd LED get on and off 5 times!
