Me: can I get some help on my project?
All of my STEM friends:
Given your history of extremely odd, possibly dangerous experiments, I'm unwilling to assist
The first thing I remember doing was taking apart a disposable camera and got to remove the flash cap, yeah, I did exactly what you're thinking but in a complex way. I grabbed my brother's toy truck that used AA batteries and put the cap there. The bang from the spark was so loud it startled the neighbors who thought someone was shot, the toy was obviously completely obliterated and the cap literally fused to the battery terminals. My mom hit me so hard with the belt it left a scar on my back, I was 7 yo at the time.
After that everything went sort of downhill I guess lol
Now a leaf blower out of a stock fan? well, could work if it's a miniature, did you know most Intel stock fans can work up to 17V and sound like a legitimate jet engine? Fact. Ghetto overclocked PC builds will be grateful, won't last long at that voltage but definitely drops temps by a few degrees, tested it paired with the tall stock heatsink.
Don't give up on your experiments OP, just don't go daredevil when handling live wires, caps or power supplies. Time isn't wasted if your gadgets serve a purpose.
