Total $15 (I thought it was $10 in the video) and smaller than a Tic Tac box as promised. I will add the remote solenoid but it will not add much to the footprint. Maybe 25% bigger. jimmy1973 I hope this works for you. Let me know if you want something changed. I can add a reset button if you don't like the gate reset. I can also add a status LED and a dimmer for the display. I chose not to based on your requirement of "small as possible".

Display $10

Arduino $2

Micro-switch $1

Phototransistor $2

Wow Chuy, that’s amazing. Love the name! Lol no changes for me that’s for sure. What’s the power source you are running it on in this video? Can I run it with a usb cord powered off a laptop?
Again, amazing work man.

jimmy1973 , yes, it can run off the USB but these Nanos use the old mini-B and it is not as common as the micro-B (see below, mini on left, micro on right). It currently is powered off a 12V wall wart that I will include with the timer. It can use any power supply from 6V to 20V.
