Default Arduino Nano based GC control

Since I could not find anything I liked already on sale, I decided to play with Arduino Nano for the first time and build everything I wanted to have for proper amp control. I was surprised how much functionality and fun I could get from ~10 eur worth of parts (with shipping!).

Features:

1) IR remote channel switching and power on/off
2) tactile panel buttons power and channel switching
3) 16x2 display for input, temp and power states
4) Temp sensing and auto shut off
5) Soft start

Now, I just need some suggestions for volume control. Motorized pot or something better? Array of relays with high quality resistors maybe?

I stumbled upon this very interesting article:

Http://diyaudioprojects.com/Solid/DI...ve-Attenuator/

And Ldr really seems like a way to go! I am planning to have nothing on the front panel but an oled window, with volume, power and input control done by IR remote, and possibly even over wifi.

Default How do you power up the arduino nano?

Hi,

I like a lot your idea. Did you mount a chipamp kit with PSU and a transformer? how do you power up the arduino nano?
