I believe it should because it has the same microcontroller as the Arduino Leonardo, which does support keyboard inputs (https://www.arduino.cc/en/Reference/MouseKeyboard). However, there might be certain compatibility issues that other members may know about, so don't quote me on this.

Same. It's quite an interesting and novel idea.

Don't quote me on this, but probably a difference in strength, as well as the conductivity (although the differences would be relatively minimal, I imagine).

I have a suggestions with the links as well. Can the links be made like when you click on them that the link doesn't open in current page you're watching. It would be much better if they would open in new tab. I know you can right click it but it would be easier if there is a way. I have a feeling ...

Whoa Now THAT's a bench - Fluke, H̶P̶ ̶A̶g̶i̶l̶e̶n̶t̶ Keysight, LeCroy(?), it's all there!

Definitely. Resistors are okay, but capacitors are usually a big no-no - especially from lower-quality brands. These capacitors may have been stressed a lot and are prone to failure.

Looks like that's been done, thanks mods!

Okay, thank you for the help.

Those googly eyes though... :D I've had relatively good success with this USB hub: http://www.amazon.com/kenable-Port-Powered-Allows-Devices/dp/B00LK5I8N0 It's extremely cheap and has a small form factor, although it's obviously not as versatile as the ones mentioned here. I'll be doing a build log ...

This is probably silly, but you have tried the volume trimpot on the amplifier?
