Jeri Ellsworth is a wizard! A huge inspiration to me.

I always loved this floppy drive reverb she made: https://www.youtube.com/watch?v=Xpr7B-7BFP4

Jeri Ellsworth, for people who don't know, does really interesting hardware stuff.

"TSA body imaging at home" (http://www.youtube.com/watch?v=vDyo_OQFdAc)

"Home made EL wire" (http://www.youtube.com/watch?v=3RKBGxJJmwg)

"Recording Audio onto floppy discs" (http://www.youtube.com/watch?v=Xpr7B-7BFP4)

"Home made transistor" (http://www.youtube.com/watch?v=-Qph8BNrnLY)

"Homebrew NMOS transistor" (http://www.youtube.com/watch?v=w_znRopGtbE)

⬐ wavefunction

I stay in my parent's basement so I don't have to be subjected to TSA body imaging, why would I want to do it at home?

j/k it's more of a tin-foil covered shed, but there may be some evidence that tHz radiation causes "resonance effects" resulting in DNA depolymerization:

So get the pat down folks, your genes will thank you!

⬐ widdershins

She did that as a protest against airport scanners, I believe.

⬐ at-fates-hands

You are correct. It was to demonstrate they were wasting absurd amounts of money paying for these when they can be built fairly easily for quite a bit less.

⬐ wavefunction

I guess my point, from the links provided, is that we shouldn't be bombarding ourselves with the radiation these devices produce.

⬐ chc

It's about the same as what you get from eating a banana AFAIK. At any rate, people routinely subject themselves to much higher doses of radiation.

⬐ ubercore

It's actually higher than a Banana Equivalent Dose, and you can't always directly compare radiation exposure like that based on dosage.

⬐ chc

Is it? A BED is about 0.08 µSv. From everything I've heard, the TSA machines dose you with somewhere between 0.02 and 0.08 µSv.

⬐ vwinsyee

I honestly thought that you and chc were joking about the Banana Equivalent Dose. But it turns out that it's a real concept!

Well, now I know how the Cocteau Twins made their sounds in the 80s!

⬐ sethg

When I saw the title, I recalled the sounds that the old Apple floppy drives would make: when you booted them up you could hear the chunka-chunka-chunka as the stepper motor pushed the head all the way to the outer track, and then a little scraping noise when (after the rest of the driver had been read off the outer track) the head moved to the center track to read the directory. And the farting noise it made before the console beeped and said “I/O ERROR”... those were the days... kids today, they don’t know what it was like....
