On: Making My Own USB Keyboard from Scratch

[goodwork]

I wanted to make 12v instant failover UPS.

No idea how can i make DC to DC UPS with easily available items

I've 12v 0.5amp requirement @6watt.

I need this appliance to be running for 5-6 hours when power has failed.

Does anyone know of the community where I can ask such question?
