Amplifier PCB

I designed a complete enclosure to house my previously designed tpa3116 2x50w amplifier board.

The design includes a 10A fuse to protect the amplifier board in case of a short-circiut or a reverse polarity of the power supply. I also fitted the amplifier ic with a heat sink which help the amplifier to achive the desired 2x50W of output power.

The enclosure is equipped whits several 5mm banana plugs for power transfer and 2 pairs of audio signal jacks.

Simple Contactless hand sanitizer / Soap Dispenser

Automatic hand sanitizer using a 9 gram servo, ultrasonic proximity sensor and arduino nano. The mechanism is very simple using only a string to push down on the cap of the hand sanitizer.
