I can't find the old thread. But here is the two transistors booster
model and schematic, as promised.

For BC847B, 6V to 15V @ 1ma:

Blocking oscillator boost converter:

So draw us a boost converter that has no current spikes.

I liked your tinylogic circuit - but I think linnix wants to do it
just with discrete semis and an inductor. I suppose transistors are
*very* cheap.

I wonder is there a better 2-transistor circuit?
