The greatest wireless contact mic fail of all time

[@theoakun3635]

typically that noise is what's called a ground loop... you would have to isolate the power grounds on both the transmiter and the reciever... there is such a component as an isolated dc-dc conerter.

Thanks for the tip!

I am so glad you make all the mistakes before I have to. Well probly not all of them. So cool. So the wireless chip had no filtering for power?

[@kenshorley]

Great video! I have had similar digital noise issues with a micro synth when powered by USB. But when I power it with a 9V battery, the noise mostly goes away.

I loved both Cliffs Of Dover refrences!

[@smugwolff6828]

this actually looks mildly useful to me for one of my many stupid projects i never finish would need to be smaller though which would not be too hard to do since yours is made on a bulky breadboard

[@PeteLaric]

Good to see that you are still completely unhinged, Mike. We should hang out.....

[@metalmarshmallowllc]

You are relatively nearby aren't you? Come up sometime!

I was thinking about Bluetooth a while back, to see if I could use my binaural devices with it, so I found this very interesting!

[@metalmarshmallowllc]

Haha, I fail so that others may succeed / suffer so others may live!

[@johnwhite5818]

koth reference?

[@metalmarshmallowllc]

Dang it Bobby, terrible show, awesome music 👍

I've had good luck with Xbees for command & control of small robots. Could theoretically be used to send/receive audio data, but you would have to check the data rate. There are many different models with different range & data rate specs. Frustrating that the modules you used don't support the audio modes you were trying to implement. I have always found Bluetooth to be an extremely unreliable and frustrating technology.

[@metalmarshmallowllc]

I was using Xbees a few years back -- I recall them sending data at serial baud rates, like a few kilobits per second; too slow for audio. Do you know if you can get faster throughput?

[@metalmarshmallowllc]

Oh I forgot to say that I over-whitened my teeth in the thumbnail just for you hahah

[@PeteLaric]

@@metalmarshmallowllc A lot of them will go up to 250 kbps from what I've seen, so that would limit your sampling rate to 15.6 kilosamples at 16 bit (assuming no parity/CRC) with a Nyquist of 7.8 kHz. With some on-the-fly compression, you might be able to make it work, although probably not for pro audio applications.
