Brilliant! What should the distance between the plates be? Is there a minimum or maximum? (Also, how even does it have to be?)Can the ratio of ferrofluid to mineral oil be altered? What would the effect be?

For ESD mats in general, why should the top layer be insulating? I don't get it. If it insulates, then surely there's no point in the conductive layer? With such two layers, nothing can reach the bottom (conductive) layer through the top (insulating) layer?

I haven't found clips like that anywhere! Where did you get them? (Bulldog or crocodile clips aren't my thing). Thanks!!

Is the Best PCB Etchant in Every Kitchen ?
This is the funniest thing I've ever seen! Haven't laughed that hard in a long time :) Absolutely genius! Honestly man you have a talent. And well done with the electronics too :) You should find out what you can about manufacturing and selling this. Go to kickstarter for funding and sales. I'm sure you can find ways of manufacturing it. The only thing you'll need help with is getting it CE marked (eg check it is EMC compliant and safe etc). It will be a challenge but it will set you up for life to have that skill.

You know, it's quite funny.... this literally gave me nightmares last night. Someone was chasing me with an electrified mains voltage cable coming from this device. And I think it was @SauHadl :-p
You're excused... please forgive my knowledge on surgery from my YouTube experience.... I'll restrict my self to pulling friends' teeth and similar minor surgeries
Just wait till a stray wire pulls the PIR sensor up to 230v, then you'll want to stay away from it, I promise
I must commend you on your openness about the whole thing. What I worry about is people who ignore advice, believing they know everything. And the last thing this site needs is people making kids think something is safe by saying it's safe even when professionals are saying it's not. I know this isn't a kids' project, but plenty of teenagers give these things a shot, and having just one or two adults saying it's safe is enough to make them think it'll be fine. Kids don't know the difference between good and bad advice.

What can be used for shims? I always end up scrapping my own linear rails in favour of openrail, v-slot or other linear bearing systems because of tolerance problems. Shim washers, for example, are expensive for what they are and costs quickly mount up
