in other words its the same circuit, hastily made on veroboard (no PCB or potting compound??) put in a box accompanied by shameless self promotion.
the fact has been pointed out in other places at other times, and yes, the open source schematic that is "made for profit" is freely available elsewhere.
the only "error" in the schematics, is that you mentioned wanting to make one, and asked for advice from someone with vested interests in what is, once again, open source, common property, un-patented, un-licensed, un-authorized in any manner...
this is yet another case of the proverbial goose chase, nothing more.
said it so many times...why waste time frigging around with what achieves little if anything at all?
from the sounds of it, you expect to be popping wheelies by the addition of an ignition system?
all you may achieve is better soldering and/or component sourcing therefore some marginal increase in reliability. usually not, unless you pot your circuit.
anyone with half a brain can see the two schematics so far posted are the same... take a real close look...oh, lets see...4.7 uf...oh, .47 uf! oh my, 1k and 33 ohm and a diode...what else? each and every component?
learn how the circuit works and modify it yourself is the best procedure...there is no "updated" schematic because THERE IS NO NEED FOR IT.
