A really cool phenomenon I found and a feature idea dump.

A really cool thing I found happens when playing with a passive buzzer. I was bored and decided to hook up a passive buzzer to g25 and to ground (the pins are the perfect length) and I set the RF tx pin to g25. Then I tried sending some jamming frequencies through it. I’d recommend to try it yourself because it’s really cool! Also I did the same for TV-B-gone and it also sounds really cool.
Ok now for some features I think would be cool.

1. Usage of the inbuilt mic to record stuff. It would be a nice add on and you could use it like you see the spies in movies do.
2. To be able to play music through the buzzer? I’m no programmer (yet ;) but it couldn’t possibly be too hard if the IR signals seemed to make many different notes. Could his be reproduced in a controlled manner with the inbuilt buzzer?
3. Just in general more buzzer usage. The buzzer is only used on boot for 2 short beeps, and that’s it. It would be cool if it would beep when entering menus, executing functions, and so on. And also definitely a silent mode because you gotta have that.

Oh also another feature I think would be really awesome is being able to send frequencies to a selected pin. In the "other" category, placing a function where you say what pin, sine or square wave, and what frequency, and it shoots that frequency out of that pin. And also if possible PWM in that same menu would be great. Would be super useful for testing and prototyping things.
