asciilifeform: i once set about building this one too - but life got in the way.
asciilifeform: (helmholtz coil with plumbing for water - must actively cool - and a power source similar to what one might find in a large stroboscope.)
asciilifeform: mircea_popescu: i vaguely recall an experiment from the '70s where everyone who was placed in apparatus had seizure. from ordinary flash lamp - but not at the familiar 20hz which sets off known sufferers
asciilifeform: mircea_popescu: actually, there's a way.
asciilifeform: (there's a commercial product in usa with earclips, forget which.)
asciilifeform: americans, if i recall, tried ear-to-ear.
asciilifeform: kakobrekla: used own replica of old soviet mask, anode on eyelids, cathode on occiput
asciilifeform: kakobrekla: for the latter, i never found a satisfactory setting where i could pronounce the old papers - replicated. but the usual idea is to set 100-200 Hz, square wave (some insist sinusoid instead), constant current (not constant voltage) output, and ramp up from zero.
asciilifeform: kakobrekla: again, values for which. girlfat, or for stage 4 sleep?
asciilifeform: salt water is great for electric chair, where the action is over in minutes, but useless here. use the green gel that is sold for eeg machines.
asciilifeform: use square wave with no dc offset (or your partner will grumble, chemical burns from hcl)
asciilifeform: he felt in his mouth—otherwise the straps around his throat would break his neck.” “That’s cotton wool?” asked the Traveler and bent down. “Yes, it is,” said the Officer smiling,“feel it for yourself.”''
asciilifeform: ''There are straps for the hands here, for the feet here, and for the throat here, to tie him in securely. At the head of the bed here, where the man, as I have mentioned, first lies face down, is this small protruding lump of felt, which can easily be adjusted so that it presses right into the man’s mouth. Its purpose is to prevent him screaming and biting his tongue to pieces. Of course, the man has to let t
asciilifeform: beautiful comic, but missing the gag pad, which is why i even remembered about der strafkolonie - jurov's toothmark authenticator.
asciilifeform: (that's -exactly- how i pictured it. and why herr kafka never gets credit for inventing dot-matrix printer, i'll never understand. this confounded me as a schoolboy.)
asciilifeform: wait - they actually franchise these ?
asciilifeform: the machines will be blamed for every faux benjamin that turns up, wherever.
asciilifeform: which is one more reason why mircea_popescu's prediction from earlier (that the 'saecular authorities' will not molest those who plunder or destroy btc atms) is likely to come true.
asciilifeform: unless i somehow misunderstand, btc atm that eats usd removes all of the element of risk from counterfeiting
asciilifeform: likewise, with casino, cheat has two basic options - win a little, but have to return many times - or win gigantic barrels, but then intense scrutiny.
asciilifeform: and his path from the door, to machines, etc. and then out, and possibly to his car - all recorded.
asciilifeform: cazalla: a casino is an example of a controlled environment. no one comes remotely near a machine - a door, hell, a toilet - without being filmed from several angles
asciilifeform: cazalla: read about how such cheats are normally caught.
asciilifeform: yes - it was: usd in, casino chips out.
asciilifeform: caught, as one expects, the old-fashioned way - spotted by guard.
asciilifeform: there was precedent, if i recall: a casino cheat in las vegas, knew exactly what a particular make of usd scanner wanted.
asciilifeform: you can try 1,000 variants until works.
asciilifeform: machine will accept or reject, but is unlikely to be programmed to rat you out (false alarms, terrible pr) and even if it were - has only a scarce idea who 'you' are (wearing your robber's mask.)
asciilifeform: it is considerably safer to experiment on the machine than on your local bank teller or other live set of eyes.
asciilifeform: (it is, in fact, a well-documented mechanism. but imagine.)
asciilifeform: TheNewDeal: let's suppose you have no idea how the machine works
asciilifeform: but picture if you were a counterfeiter - could you even wish for a better place to make use of the fakes ?
asciilifeform: right now, btc atm, as i understand, is scarce enough - and likewise scarce are the counterfeiters - that they have not yet met in 'true love' match.
asciilifeform: with machine - owner finds out, possibly weeks or months later, when he himself is prosecuted
asciilifeform: TheNewDeal: likewise, if you give a sham benjamin to a living person, he might cry out for help before you can run off.
asciilifeform: TheNewDeal: the bar is considerably lower for fooling a machine. (until recently, the readers in american vending machines did not even contain colour cameras.)
asciilifeform: jurov: this is why scammers, thieves, etc. put on mask.
asciilifeform: jurov: there's traditionally a camera on u.s. atms.
asciilifeform: TheNewDeal: hooligan inserts counterfeit usd, walks away with btc.
asciilifeform: TheNewDeal: machine, in theory, pisses out btc when you insert usd ?
asciilifeform: btc atm... 'Cash in and cash out' << clearly funded by u.s. mint, where they'd like to learn what the state of the art in fooling automated benjamin testers is.
