@Proxy: Actually, putting a coil on the wrist isn't that unfeasible. You're essentially building a Bluetooth headset, no? When you say "conversations", what do you mean? Actual audio?
-
@Proxy: Have you given any thought to the idea of a wrist magnet?
-
My immediate thought is that I wonder what advantages or disadvantages it has over inductive power.
-
:(

What is the difference between your project and, say, Erlang?

Awesome! Gotta love the pet industry. How often do you think you'll be scanning? Have you thought about putting together a wearable for constant logging? Perhaps a little armband. I've been meaning to start collecting this data for a while now. Where did you buy yours? A cursory search brings up…

@Frank, It couldn't be *that* hard. ~Drew

@Tiak, Hey, actually, I mentioned them in the first post. The biggest issues are that sound quality is less-than-awesome, and that the coil is external and you can't get great "reception" unless you hold the coil really close.
-
@MagneticJacob, I'd like to avoid transdermals, as they require regular cleaning and other maintenance, and feel more dangerous. Inductive charging, though? Definitely :)
-
@Frank, That's terrific news! Do you have any more information on this codec?
-
If you go for the wrist, make sure it's the forearm-side.

This seems relevant and interesting: http://www.medel.com/int/bci-the-implant

@mothball, As far as the coil goes, what are you looking to do? The easiest way I've found to get started with that is to buy one of these: http://www.ebay.com/itm/271288743429 Your magnetometer idea is particularly interesting to me. I've got a bunch of old Android phones (with magnetometers!) sitting around gathering…

@NuclearFantasies, I'm definitely open to other options, including building our own bone-implant with 3D-printed titanium. EDIT: Surgery Quick Start Guide: http://www.cochlear.com/wps/wcm/connect/9c7cb76b-57b8-4907-9b70-3772a4ec4b67/baha-attract-surgery-quick-guide.pdf?MOD=AJPERES Also, (according to…

Okay, so, here's the Baha® 4 Attract: The implant (BI300, far left) gets screwed into the temporal bone, and then has the internal magnet (BIM400) attached to it. The sound processor (far right) is, as far as I'm concerned, unnecessary; this is an augment, not a repair. My plan is to create a BI300-compatible replacement…
-
@NuclearFantasies: Interesting, that's also a transdermal; I wonder if that makes a difference.

For everyone's viewing pleasure: https://www.youtube.com/watch?v=WZJAJM_9kOw https://www.youtube.com/watch?v=ystTc_eKevQ @Cassox, would you mind elaborating more on your thoughts on DIY-ing it?

@NuclearFantasies, Currently, I'm thinking it'll be necessary to include a battery that can be charged with induction. Osseointegration looks like it's well-studied. I wonder how small of a battery I can get. It's basically just a Bluetooth bone-conduction headset, implanted into the skull. Another idea is to use the…
-
@NuclearFantasies, thanks! You got me started with looking at bone conduction, so thanks for that, too. Looks like power is still going to be the biggest problem. As usual. Damn.
-
I basically want just the implant part of this: http://www.cochlear.com/wps/wcm/connect/us/home/treatment-options-for-hearing-loss/bone-conduction-implants/baha-4-attract-system/baha-4-attract-system But with a wireless link to it, and without the magnet. Thoughts?
-
Strike that. I just did something awesome. Wearing headphones connected to my Elektrosluch 2, and playing music through from my computer through my "Spy Coil", I can hear it even if they're separated by a distance equivalent to my height, nearly six feet. So cool. If I could power a tiny wireless speaker this way, I'd be…
-
I think I might just wait a bit longer, until the power problem is solved.
-
Come to think of it, aren't passive radio receivers already a thing...? EDIT: http://en.wikipedia.org/wiki/Rectenna
-
@NuclearFantasies, I took a look at that page:A modified mobile telephone or dedicated device is used to receive the long-range signal. [...] The device then transmits a low frequency signal which energises the dormant receiver (in the tooth) by magnetic near field effects. A transducer then converts this signal into low…
-
Would those last long enough, do you think? What kind of custom design do you have in mind?
-
I'm wondering if there are suitable batteries small enough to go into a tooth.
-
@NuclearFantasies, awesome. We need to figure out batteries :)
-
@ShankT, great, I look forward to it! Yeah, actually, having it be discreet is actually somewhat important to me, too. I'm all for spearheading the future, but I'd like to have the option of keeping my pursuits secret.
-
@ShankT, I'm very interested in your project, are the details public?
