What do you think? This plus another <$10 in parts to build a microcontoller (ATTiny/Arduino) at each end... wireless channel/feature switching?

I've been meaning to incorporate a micro in a build, just never got around to it. I have used remote telemetry and it worked for data, should work for tubes

You don't need a whole computer to do switching. You can buy it all pre-made.

What I have in mind would be a much more elegant solution than those key-fob devices.

One of these in my pedal enclosure (like the generic $19 3-button one from AES), and one in my amp. These are only $8 each. Even cheaper would be an 8-pin DIP ATTiny-85 chip on each end with $0.50 worth of parts and I have all the microcontroller power I need to control as many relays as I want or need for about $5 or $6 total for both ends. I would need a 3.3V power supply in the amp and my pedalboard power supply would handle the pedal end.
Plus, I love microcontroller projects. They are loads of fun. I love coding (used to do it for a living) and electronics so they go hand-in-hand for a fun project for me.
What I would be most concerned about would be if either the wireless signal or the act of putting an antenna inside a tube amp would cause any noise or interference.

I love coding
I used to but I'm finding my 'ol brain doesn't stay focused as well, it gets bored :laugh:
I cleaned up an old XP notepad with the intention of learning C+, so far I wrote a small routine that locks the computer when executed :icon_biggrin:
maybe i'll just stick with my Basic Stamps!
-
That's too funny. You shoud go to that Oddwires.com site and get an Arduino starter kit. There are gazillions of good tutorials online for learning them. Way more powerful and flexible than a basic stamp.
-
Way more powerful
Ya, but I haven't found an application that I've used that needs more power. I get the code, what hozzes my senior brain is all the syntax, fish-lips, slashes and dashes...... I have python, got past "hello world", simple routines, then I tried data collection and store, that's where things went sideways!, I went back to Basic!
this is a site I pick up "odd" things for my stamps,

Very cool. Yeah a lot can be said for sticking with what you are comfortable with and can get up and running quickly for sure.
One thing I like about Arduino is you can build your own and save a bit of money and space. And if you don't need all those IO pins you can use a smaller ATMega chip to save even more space.
Adafruit is a fun site. I use them quite a bit too. I love the Neopixels!
