That's brilliant Charlie, can't believe what you've managed to sort out in a day. Really enjoying these little update videos.

I'm enjoying the updates Charlie. I really like the idea of the audio and CAT on the same USB, I had put that into the too hard basket for my own projects but I might revisit that.

I am glad it worked out. The Teensy seems to be able to handle the load. I need to get one and put it through its paces. You once again prove the old adage: don’t let a theoretical concern stop you from trying it out.

This looks like it is developing into a fun little rig with a very concise design philosophy. I bet it would be marketable.

Well done. Charlie KM4ZZ

Hello from Canada Charlie. Recently I was looking at your vid that was talking about mixers(2 general types) one was driven at 10ma and the other driven at 2 ma. Can you advise which mixers you were recommending? Thanks in Advance.

Wow you've made progress. I guess having some previous built blocks helps.
Are you using the audio shield for audio capture? Is it practical to increase the sampling rate and bit depth? When I looked at it a while back it looked to me like the audio library was fairly hard coded to CD quality.
Keep up the updates.!
