What is the absolutely simplest way for a 10 year old child (not really) to get a 5V (350mA) phone charger to power an LED (3.0V) and a clock (1.5V)?
The clock is meant to run on a 1.5V battery, but since I want to install a small LED, I thought why not run both light and clock on the same power supply.
I need it to be not bigger than a cigarette pack (preferably smaller.)
I don't understand electronics jargon so please treat me like a child.
I originally thought I could just solder on some resistors but there's no info online I could use to be found.
Let me know if there's anything else I forgot to include.
