Indeed. When I was 16 I wasn't able to "get funding" for a lab bench power supply.
I resorted to building one off an used ATX computer power supply, but voltages fluctuated a lot and also it was pretty high and non-regulable in current output. That was a recipe for troubles. Indeed, when one of the first boards I was learning on caught fire (mis-configured potentiometer + non-limited current dwaw) I didn't feel safe anymore to continue and basically stopped doing that kind of stuff.
So yeah, extremely impressive achievement for a 13 years old student, not downplaying his achievement, but it's wrong to understate the role that his parents and their funding had.
- PaulAJ 6y agoYou had a used ATX power supply?! You were LUCKY!. When I were a lad, all we had was a bike dynamo. And you had to crank it by hand... https://www.youtube.com/watch?v=ue7wM0QC5LE https://www.youtube.com/watch?v=ue7wM0QC5LE

Sorry, this gave me a chuckle as it effectively encapsulates engineers. The "Light Emitting Resistor" is a rite of passage. It's when you finally understand that it's called "Ohm's Law" for a reason.
