okay see this is kind of what i was talking about ff
Now do the following. Fill a plastic sphere with iron powder and make a solenoid and make the black powder stick to the top of the sphere. Just an idea.
>for what?
If you make a lot of them you could make a really shitty big screen.
step one, learn fundamentals of electricity before trying "cool" stuff. step two, repeat step one until you realize why arduino/raspberry pi is the goat device of diy trogs.
Anon we're just going through the motions at this point. Sorry.

>step one, learn fundamentals of electricity before trying "cool" stuff.
The best way to learn is by doing, and failing, and doing again.
okay then how about leaving your mothers basement and mixing all the funny liquids into the sink. better yet, keep learning some stuff then come back and post something more interesting.
OH NO ANON MADE A NAIL HOT
HE SHOULD HAVE CHECKED WITH OSHA FIRST
Did you even try it to see if it was magnetized? Come on now.
It sure was
now to figure out how to stop the wire from melting
Measure the resistance of the coil before applying voltage. Power equals voltage squared divided by residence. If you get something absurd like 100 W, think of what that would imply.
Resistance, not residence.
At 12 volts, 5-10 W makes sense so you would need about 14-28 ohms. I bet you had 1 or 2 ohms.
Or 0, kek.
but how do I increase the resistance?
connect the wire to a pencil lead.
Resistance is proportional to wire length. More wire is more resistance.
>didn't mention that the coil was bare copper wire
Congratulations, Tyrone. You made a cigarette lighter.
>missing the point
The point us frick your feelings kek
this thread is same gayging so bad its not even funny
literally 0 samegayging
suuuuuuuuure
why
