I've arranged my electronics class through Studio Bricolage.

Dates are April 7, 9, and 14, at Leonardo's Basement. I'm expecting each session to be less than 2 hours in length, and I'm aiming for less than one hour of blah blah blah so we can actually get some playing done. There's no charge for the class, but there is an optional $15 materials fee for some small goodies packs I'm assembling.

Please, please, PLEASE pre-register if you are interested in getting the goodies pack. I bought some wire and breadboards at Fry's today (unbelievably cheap), and I'm culling some of the rest from my personal stash and a likely upcoming order from Digi-key or Jameco. I don't want anyone to feel left out.

Once I have the complete pack assembled, I will post it here, so you can decide on whether or not you want to buy it or try and use stuff you already have. I'll probably bring extra bits and pieces, "just in case".

I also STRONGLY suggest you bring a simple multimeter. Doesn't have to be much- just amps, volts and ohms. Multimeters of that sort can be had for $20 or less, and if you're planning on doing much with electronics, a meter is pretty much essential.

If this goes well, I'll probably do more classes in the future.

If you have questions, let 'em fly. To register, hit the Studio Bricolage site for contact info, as they're doing the leg-work of the organizing.

can you give a more specific idea of what you'll be covering?

Wait, Fry's? Did you order from there, or is there a brick and mortar around that I am not aware of?

See the casual meetup thread, he's in CA for work.

Basics of Electronics... mostly outlined in this thread.

Items to be covered in the class:

Day 1- basic concepts: what is a volt, an amp, an ohm, a watt, and (briefly) a farad? How do they relate? What is AC current versus DC current? What is a resistor? What is a capacitor? What is a diode? What is an LED? The hands-on will cover reading resistor values, constructing a desired value of resistance from parallel and series resistors, creating a voltage divider, powering an LED, using a potentiometer, and, briefly, RC time constants.

Day 2- powering circuits: DC sources (wall warts and batteries), power connectors, reverse-polarity protection with diodes, voltage regulation ICs, transformers, fuses and dimmer switches. The hands-on will cover putting a voltage regulation IC into play, setting the voltage on a common adjustable voltage regulation IC (to provide power other than 5V), using a 7660 IC to easily generate a low-current negative voltage rail for biasing op-amps and analog circuits.

Day 3- basic uses transistors (MOSFET and BJT, N and P type, and the differences between the two), op-amp basics (the rules of virtual open and virtual short), the importance of power supply bypassing in integrated circuit usage, and a laundry list of my favorite integrated circuits (this is something that was never really presented to me, so until I started figuring this out on my own, I spent a lot of time and effort devising crazy methods to do things that could be done with a fairly simple off-the-shelf component). The hands-on will cover using a PMOSFET to provide a better means of protecting your circuit from reverse battery insertion, using PWM to dim an LED (demonstrated using my Magic Square Wave Generator IC), and demonstrations of using transistors to switch power loads highlighting the benefits and drawbacks of BJTs and FETs for certain applications.

sweet!
i signed me up for some good electronics times then. (sent an email to the studio bric add)
thanks for doing this mike! it'll get more folks around to knowing what theyre doing with this stuff.
