Today, I finally created the circuit diagrams. Until now, there was only my scribbling.
A cool facet of Pintopia is partnering up with another artist's campaign - Short Circuit is paired with Bunnies & Branchs! If you buy at least one pin from both of us, you also get BOTH of these pins for free!!

In a series RLC circuit with a dc source, if L equals C then determine the value of R such that the voltage across the capacitor is critically damped.
a) R = .5
b) R = 2
c) R = .5/L
d) none of the above
#STEM #STEAM #Circuits #Engineer #Engineering #NoireSTEMinist In a source-free series RLC circuit, if the resistor is replaced with a wire then the voltage across the capacitor is
a) underdamped
b) overdamped
c) critically damped
d) undamped
I would love to get 100 folks following the prelaunch page of this before November ends (currently at 90) - if you know someone you think would enjoy these pin designs, please spread the word! :D

Going to be adding more of a teaser soon as well, so keep those eyeballs peeled.

Just got a screaming deal on an 18" Insignia monitor... and the damn main board is cracked in two places.
Time to break out some epoxy and the *really fine* dremel tips to see if I can rework these traces! There's about 20 that need to be done, and most of them are pretty big (but there are 7 that might be too fine for me to handle, so those might get wire instead).
In any case, it's been awhile since I've tried to tackle a project like this... but I *really* want this monitor to work!

Scooter parts arrived today! Bought them from these peeps: https://www.ebay.com/str/overvoltedscooters. The charger came from Amazon. Just type in the usual Amazon url and tack this onto the end: /dp/B001RMPABE. (Doing it this way so the original link gets all the attention. :P )
And yes, you're seeing that right; THAT'S A KEYHOLE SWITCH. ON A VARIABLE SPEED CONTROLLER. I can't wait to get working on the E300 again!! EEEEEEEEEEEEEE_ :D
(If you want to contact them, they put their number in their listings.)
I just looked it up and I didn't realize that there are no freedom units for electricity and magnetism. I have no idea why the US is so strident on continuing the use of Imperial; I don't get it.
The volt as a unit would take a much longer time to explain than necessary just from the fact that you need to explain both the joule and the ampere, for instance.
If you haven't say like, taken a circuits class in the US, it kinda stinks to not even understand how volts and amps translate to watts, and then to calculate how much energy you use with the electronics you have in your house. The silly kilowatt-hours unit would probably not exist if people understood joules as a unit.
