- bane 6y agoDo you have any info on this? The only imaging I'm familiar with are medical.
- snypher 6y agoMaybe check out https://kelu124.gitbooks.io/echomods/content/RPI.html https://kelu124.gitbooks.io/echomods/content/RPI.html
- tinus_hn 6y agoAmazing, can I buy one of these sets?
- frongpik 6y agoAny TV with 2 mics. Those TVs are called smart for a reason.
- smangold 6y agoIt is more a demo of a full duplex single lonk using twi frequencies (one for each direction), instead of networking. It might be interesting to add a MAC protocol. Interesting work.
- tashbarg 6y ago> You can see that we transmit in this example at two different frequencies, 19kHz and 18kHz. Not „just out of hearing range“ for some people. Especially young people can hear up to 20kHz.
