Based on your recent post, I think you are what you have said.
You are paranoid and egoistic.
If all you care is NASA or MIL-STD quality, then don't spam on a forum with most users making consumer/industrial stuff for a living.

have you ever seen a large gasoline fire ball go off? Or a 15 inch shell explode? Or maybe some high explosives someone had laying around to add some ground boom to a show?
You can connect this thing to a fused blasting cap if you want.
What do you think I am complaining about a fucking alarm clock? It's a detonator circuit.
Do you think someone is gonna give a shit about class D restrictions at a private party or something? :palm: :palm: :palm:
I think its just people that never experienced a close up explosion or real heat in their life talking a buncha idiotic shit in this thread.

That, or biased to check for continuity (and no more! :) ).
IIRC from last year's thread, the design is well conceived and proven. This is just biggermoar. ;D

yes, outputs are shunted when idle.
last year's design worked very well, this is version 2.

That's not a lamp filament blasting cap (FBI, don't knock on my door). Those are professional detonators designed for field application.
Let the legislation done by UL, and just buy UL certified products. There's no need to reinvent the wheels or to add paranoia.
Of course, if you buy non certified detonators for use with large quantity of explosives, Darwin gets you, sooner or later.
FYI, I had a good interest in energetic materials, and for the record, I've made black powder, NI3, TNT, picric acid, nitrocellulose and nitroglycerin during my primary school to college days.
I've also dived into theoretical calculation of synthesis of RDX and HMX.
Furthermore, I had fun with strong acids and TMAl, t-BuLi and some other nasty stuffs.
I currently have some strong acid blend for decapping chips within arms reach, and I'm only wearing a boxer and a shirt.
To date, I still have 10 fingers and 10 toes plus 2 functioning eyes.

you can put a pound of black powder in the bottom of a pale, stick a light bulb igniter in it, then put a 20 gallon bag of gasoline on top of it to make a show firework or possibly thermal weapon if you aim at at a convoy passing by, regardless they are a popular finisher for fireworks show because it looks like a stereotypical atom bomb. Also popular for movie effects where they don't want to get high explosives license etc.
I don't care what compounds you made, have you ever been close to a powerful explosion or fire ? I made plenty of compounds but manufacture or small chemistry lab test burn or detonating some matchhead sized pile of crap with a hammer won't give you the same sensibilities as experiencing a thermal burn from far away or getting nailed with a shock wave.

"class d"? "15 inch shell"? gasoline? high explosives? 500g flash salute? quick match with time fuse? what in the world are you blathering on about? you're just making shit up. no pyro talks like that. you have already proven you know nothing about the industry.
this is 1.4g you idiot. i'm not hooking it up to blasting caps and i am not doing any of those things you are drivelling on about.
stop posting, you have a terminal case of stupid. the only idiotic shit being posted in this thread is from you.

Things can always go wrong, even for the professionals. In 2012 I saw the San Diego barge fireworks intended for a 17 minute show turn into a very energetic 30 second show. ALL the fireworks went off at once!
