Basic Electronics Class #2

You will learn:

How to use a breadboard
What capacitors are
How to use capacitors for filtering power
How to use capacitors for basic debounce/timing circuits
Connect a 555 timer circuit for blinking an LED

This will require the purchase of a breadboard and some more expensive parts that last time (I'm thinking it will be about $15 -- I may need to adjust this after I buy the parts). I will bulk-order and get everyone more parts that you need.

700pt breadboard (Like this: http://www.surplus-electronics-sales.com/index.php?main_page=product_info&cPath=16&products_id=183)
A few voltage regulators (LM317, 7805) in TO-220 packages
A few 555 timers (DIP-8)
A couple potentiometers (5k, 10k, linear taper)
More resistors (assortment)
Some capacitors (.1uF, 1uF, 10uF)
etc.

I'll update this as I develop the slides.

You will need to bring:

1 power supply - can be a wall transformer that is between 9 and 15 VDC and greater than 200mA output. You should be able to salvage on of these from any number of places.

22ga Solid Core wire (for connecting to you breadboard)
Some kind of wire cutters. I got some of these the other day:
(Small version - will handle anything that can fit on a breadboard) http://www.amazon.com/gp/product/B000IBOOSA/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1

Some kind of wire strippers. I like these but any kind that can strip 22ga solid wire is fine.

The parts kit from the last class (need the resistors, LEDs, and multimeter from it) or you can buy a kit for $5 (we may not have more multimeters available if you wait too long)

Either $15 or all of the parts that I listed in the parts section above.

    Great as usual. Felt like a little duckling in unknown waters. Glad the bigger ducks helped out.

      :D I didn't know I left anything. Thanks for letting me know. Do you still have my email? Thanks again.

      Fiona, I was mistaken. After you left, someone placed something next to me, and then was wandering around, so I thought it was yours! You took my email, but I did not get yours.

    I had a great time. Was really nice getting back into electronics. They are very knowledgeable. I'll have to start some projects soon.

      If it's not too late, I'll take a kit (sorry, thought this was already answered in the sign up page for the event).

      April 9, 2013

    • Summer

      Hi Jason, I would also like a kit

    Darn...I now have to work late...

    It looks like 14 people are signed up right now but only 8 want parts kits. Please make sure that you reply if you want a kit. I will not have many extras.

    For all of those who are asking questions about what to bring, the list is not yet comprehensive but yes, you still need cutters, wire, strippers, and a power supply of some kind. I can't in good conscience buy a bunch of wall transformer power supplies when I know that most of you have a drawer full of these that you just can't throw away.

  • Carol N.

    Where do you all get the piece of 20 ga wire? I thinkyou have to buy a big spool for $7.00. Anyone got an extra piece of wire?

    March 28, 2013

  • Gerhart H.

    I've decided I would also like the 15 dollar kit. So with the 15 dollar kit we still need to bring wire cutter/strippers, wire and a power supply?

    You need an AC adapter between 9 and 15 VDC and greater than 200mA output. It is impossible to tell if a "power cord for a cell phone" meets these specifications from what you described.

    Yes, you need insulated wire unless you want to have a lot of issues with shorts.

    March 26, 2013

  • Carol N.

    Can we use the power cord for a cell phone or cordless phone? How do we know the thingy will fit into whereever we are plugging it into. The 22ga solid core wire has to be insulated right, I can't just use my 22ga beading wire?

  • Carol N.

    Carol would like a big a parts and a new brain. TYVM

  • Jason L.

    I will also take a bag of parts please :-)

    March 25, 2013

  • Micheal Shawn O.

    I would like to buy a bag of parts

    March 25, 2013

  • Brian P.

    Looking forward to meeting everyone and learning! Sad I missed the 1st class.

    March 24, 2013

  • Jason L.

    I think I have most of this, but I may just get the parts from you guys again. It's nice to have the same parts. Leads to less confusion :-)
