# VACRIP - Voltage, Amperage, Capacitors, Resistors, Inductors and Power

• Jul 12, 2014 · 10:15 AM

This is a whirlwind tour of the most basic of basics for working with electronics.
We will learn:
* How to think of voltage and amperage (you can't see it... sometimes you feel it! what is it?)
* Ohm's Law and resistors. Yes it is math. It is easy math, just bring a calculator and/or smartphone.
* Kirkhoff's Voltage Law. If you break this simple law, your fine is paid in burned out components. It turns out it is easy to learn how to avoid that.
* Capacitors. How they work and why they are your friends.
* Inductors. A little more tricky, and a few tips to help use them. Bring your Motors!
* Power - Or - Why is my circuit board so hot?

There will be an opportunity to do small, simple circuits to demonstrate Ohms Law and capacitors and such. If you want to, bring your bread-boards, your jumper wires, your resistors and capacitors and a battery pack and such to run your experiments with. The beauty of doing that at our meetup is that when something doesn't work, there are many around who can help you.

See you Saturday!

So ... do we need our Arduinos? and what kind of power pack would be useful to bring?

No, no need to bring Arduino for this presentation. On the other hand no one with an Arduino will be turned away...

I just got some thin foam sheets for making walk along gliders, as well as two pre-made mosquito gliders from http://www.sciencetoymaker.org/. I'll bring them to demo. Also, I may share the tiny bit of progress I've made on my home made Solowheel (basically, I'm working on getting the controller wired up to the motor properly). [The Solowheel is a Segway like, self balancing one wheeled vehicle.]

Is this going to be a presentation? I'd love to see slides or something. I really want to know this stuff but will be unable to attend on this day. =(

Maybe we can post some notes afterwards.

Yes Jason, I am madly scrambling to put together what I hope will be a helpful slide deck. Much more useful though to hear the descriptions with the images. There will also be demo and bread-boarding and such which is sometimes even more helpful. Perhaps we can do it again some time so you can get the rest of it.

Remember that we will also have Show and Tell before the circuit work. If you are planning on bringing something cool you can let people know about it by posting a message here.
