The new material, made of silica-coated copper nanowires encased in a polymer matrix, encodes information not in states of charge but instead in states of resistance. By applying a small voltage, it can be switched between a state of high resistance, which stops electric current, and a state of low resistance, which allows current to flow. And, unlike silicon, the nanowires and the polymer can be dissolved in methanol, creating a liquid that can be sprayed through the nozzle of a printer.
Amazingly, its write speed is three microseconds, "rivaling the speed of flash drives." The information can be re-written many times, and the stored data can last for up to 10 years.
The printed out message included recommendations for printer owners to secure their device. The hacker said that people who reached out were very nice and thanked him.
The printers apparently spew out an ASCII drawing of a robot, along with the words "stackoverflowin the hacker god has returned. your printer is part of a flaming botnet... For the love of God, please close this port." The messages sometimes also include a link to a Twitter feed named LMAOstack.
But as pledges grew to over half a million euros, backers started to sense things didn't add up. Kevin Holmes commented "Wow, I'm stunned -- I cancelled my pledge already ... Did they really buy parts from Shapeways and pass them off as their own?" while Anthony Webb remarked "I've backed over 100 projects on Kickstarter ... but this one takes the cake for a complete scam." The company was a no-show at events it scheduled this week, including a demonstration Monday and a live stream Tuesday.
Update: Epson has responded to Slashdot, pointing us to its support page that has instructions on how to fix the issue on many of Epson printers.
