Vending Machine is Now Cyborg Friendly

Don’t you hate having to pull out your wallet or cellphone in order to pay for something? What if you could just wave your hand and transfer money that way? Well [David] did, so he decided to do something about it. He made the vending machine in his hackerspace, FamiLAB, cyborg friendly.

The problem was, the vending machine wasn’t technically his to play around with… so he had to do this hack without actually modifying the machine itself — which we admit, actually makes it quite a bit more interesting!

But first, why is [David] even doing this? Is he a cyborg or something? Well, not quite, but he’s quite enthusiastic about bio-tech (is that what we call it now?) — anyway, he has NFC implants in his hand, and magnets in his fingertips to give him a sixth “electro-sense”. Wanting to take the most advantage of these augmented abilities, he put together this clever NFC credit card emulator.

Electronically controlled NFC tag

P1010393

[Per] is replacing his car stereo with a Nexus 7 tablet. It’s a great modification to add GPS, navigation, and a good music player, but [Per] wanted to pause his tunes and tell the tablet to go to sleep with an NFC tag. This means building a an NFC tag he can turn on and off, an interesting problem to say the least.

The easiest way to do this is with a CMOS switch, but a chip like a 74HC4066 is overkill for a project this simple. What [Per] needed was a single CMOS switch, something he found and fabbed a board for.

Now, with a press of a button, [Per] can activate his NFC tag and pause the music in his new stereo. Check out the video of this electronically controllable tag after the break.
