But the tlv320aic3206 only has two channel in and two channel out. You'd need two for your goals.JayShoehttps://www.blogger.com/profile/01712183416513486405noreply@blogger.comtag:blogger.com,1999:blog-8003003859380421483.post-58356831431698349352017-12-23T08:48:23.846-08:002017-12-23T08:48:23.846-08:00Hi Chip!
Do you think that it's possible to re...Hi Chip!<br />Do you think that it's possible to re-design your Tympan PCB to smaller size? something similar to the Teensy Audio Board?<br />I need the audio board to get 4 Mics and stream them to the PC via t he USB interface...So I dont need the Bluetooth and SD card options...<br />Do you think that its possible?<br />It will work with the Teensy 3.2?<br /><br />Thanks in advance,<br />I am available at alonper@gmail.com Israeli Oakhttps://www.blogger.com/profile/09305841675400826717noreply@blogger.comtag:blogger.com,1999:blog-8003003859380421483.post-14409172691375176332017-06-07T18:13:21.509-07:002017-06-07T18:13:21.509-07:00This comment has been removed by a blog administrator.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8003003859380421483.post-2446440726255606502017-05-26T07:18:02.129-07:002017-05-26T07:18:02.129-07:00This comment has been removed by a blog administrator.UplayOnlinehttps://www.blogger.com/profile/07056159688537638797noreply@blogger.comtag:blogger.com,1999:blog-8003003859380421483.post-27853600510401181992017-04-12T22:03:17.529-07:002017-04-12T22:03:17.529-07:00I'll be actively following your projects. Back...I'll be actively following your projects. Back in October of 2015 I had surgery for an implant to use the Cochlear BAHA system. If you're unaware of the BAHA, it's a bone anchored hearing aid. Where they implanted a metal disc and magnet into my skull beneath the skin. The BAHA processor affixes to my skull via a magnet, picks up sound, vibrates my skull and transmits sound to my good ear to aid in my being deaf in my right ear.<br /><br />Well... the reality is that the BAHA really sucks. It's not powerful enough, even in a quiet room it doesn't do enough to bother. It was also really expensive, lets pretend you don't have to have surgery to use it. The processor alone sells for over $5,000, it's a rip off imo.<br /><br />But... it did light a fire under me and started a quest to find a better solution than what Cochlear sold me.<br /><br />Using a transducer sold under the name of an 'exciter' meant for turning surfaces into speakers. I bought 50 different ones that would be light and small enough to affix to the Cochlear magnets. Lots of trial and error but I found what I found to sound the best and fit the parameters of being small'n'light to magnet to my skull. Dirt cheap at $4.<br /><br />Next, I sourced a super small 'n' cheap 3W amplifier from aliexpress for $1.50. Used an 18650 battery and a lipo usb charger module. Along with an electret microphone.<br /><br />Much like your Teensy Hearing Aid setup...<br /><br />I run a wire from the output to the exciter that I use as a bone conducting transducer. Kinda looks like being a cyborg with a Walkman.<br /><br />I wear my contraption as an armband, long as you don't notice something is plugged into my skull behind my ear... it's not too self-consciousness inducing.<br /><br />Most importantly it exceeds the performance of the BAHA in my personal use by a factor of easily 10x's more effective.<br /><br />To be fair however, I'm fortunate as my good ear is indeed good. Perfect range of hearing and thus I don't have much need as others would to filter frequencies.<br /><br />But I think what you are doing is important. The extortionist prices of hearing aids are a problem. The cost of the one I had from Cochlear was so prohibitively expensive I'd never want to use it anywhere it could be bumped or broken. That rules out a lot of experiences. If I had one of these things when I was a kid, I would have developed an ulcer from worrying that I'd break or lose it and my parents would kill me. That's no good, my goals were to keep my BOM to as low as possible. The idea being that it could serve as a spare hearing aid, a back-up, something you'd use outdoors, riding a bike, around the house, the garage, etc. If it got lost or broken? Not a big deal.EChttps://www.blogger.com/profile/07824089144408127398noreply@blogger.comtag:blogger.com,1999:blog-8003003859380421483.post-58723223087846513992017-03-19T18:00:28.103-07:002017-03-19T18:00:28.103-07:00Interesting, educational, well presented.
