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!
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!
Good to see that you are still completely unhinged, Mike. We should hang out.....
You are relatively nearby aren't you? Come up sometime!
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
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!
Haha, I fail so that others may succeed / suffer so others may live!
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.
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?
Oh I forgot to say that I over-whitened my teeth in the thumbnail just for you hahah
@@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.
koth reference?
Dang it Bobby, terrible show, awesome music 👍
