TV remote rotates beer, snacks

Small rotating table. Responds to most remote controllers (38kHz carrier). Push any key on the TV remote and the table will rotate for a couple of seconds so you won't forget about your beer, snacks, cookies etc.

The base and the table is 3D printed, driven by a N20 gear motor (Aliexpress). Two shaft types are covered. Print the little wheels in 0.1mm resolution at low speed.

For every TV remote push the TSOP sensor outputs a negative pulse train. This is filtered and delayed, opens the PMOS switch, turning the motor on for about 10 sec.

The table is supplied by 5V from micro USB cable (charger, powerbank, computer USB). Some chargers have noisy outputs, these won't work.

Padding the table with soft felt or similar results in smoother turns.

LEDs and 22R should go parallel with the motor if you want illumination at the same time.
