What's a good car Bluetooth FM transmitter? > 2 Amp charger and/or Aux optional.

Is thee a lot of signal lost (quality) when using FM instead of AUX?

@Tribit Thanks for the suggestion kook aweaoneme.

I want to make an automatic pet food dispenser using an Arduino. What can I use as an electronic valve or actuator?

I picture it as a 3L soda bottle on top of a PVC 1" tube, and the actuator at the bottom.

Something really more simple than commercial pet feeders.

My 3 year old ergonomic mouse just died on me. What¿s a good replacement? Should I buy the same one? I really like it a lot.

I guess I will.

3 years later, not a better option on the chink stores.

The ones that look nice, don't have li-ion battery.
