Well done. Next project DIY IPL for those hair bears amongst us?

In general, experimenting at home with these kinds of light intensities is NOT a good idea. Way too much risk of accidental eye damage.

Cool

Hell yeah this rules
rie_t•4d ago
This is very impressive... The temptation to build my own now...
nixyhazel•4d ago
@y1n0 any chance that I can get in contact with you to help build my own?

I'm already up to several thousand in spend doing it the traditional way (which has been very helpful!) but it's not sustainable even on an upcoming big-tech salary.

thanks <3 hazel

Hell yeah. I feel like if the world ended there would be a group of trans woman with a wind powered experimental estrogen generator inside of a week.

I mean, it's just a fancy hydrocarbon, and in some form or another can be extracted from female mammal urine.

I imagine there's a way to genetically alter yeasts to make estrobeer while they're at it, with the side benefit that the alcohol would serve as a natural testosterone reducer for a double d whammy.

I have soooo many questions. Approximate hardware cost? Pain of needle? Pain of zap? How does the sensation of your machine compare to commerical applications? How long has it been since the first tests? Results from those tests? Is there some sensation that indicates having inserted to the proper depth? Is it an increase in resistance or an increase in pain? Have you used it anyhwere but the hand? Does the pain scale the same way everything else does (like the lip and chin hurt more than the arms?)

Full disclosure, I may or may not have caused some scarring having attempted to do this in a very rudimentary way with some 9volts when I thought that it was purely the heat from the electricity that we were after. This seems to be a vast improvement over the nightmare I came up with, even with the car battery as at least you've got voltage regulation.

You are a legend and an inspiration.

…it's basically a medical device designed by an idiot…

That cracked me up!

Very cool! How can I order one?

Tindie is great for this type of stuff, if OP needs a platform. Though my experience is only as a buyer.

That said, if you have a 3D printer these days the process of ordering a board with full PCBA from PCBWay/JLCPCB/Aisler and printing the case yourself is pretty easy.

Excellent hack, lovely write up. Learned about Embassy, which I didn't know yet. Thank you!
