Basic Electronics Class #2


You must register for this class on Meetup; Limited seating available.

Wednesday, April 17, 2013


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: )
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)

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)

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.

Open House Party


We’re really excited to announce that Baltimore Hackerspace has moved to a new location and we would like you to come help us celebrate.  Come socialize, learn and check out the facility. We will have our projects on display and will be doing a couple workshops. There is also a rumor that there may be food!

If you are attending I invite you to RSVP so we can get an idea of how many people are coming.

When: November 17th, 2012
Time: Noon – whenever
Where: 6410 Landay Ave. Baltimore MD 21237 MAP


Class – Getting Bootstrapped with Git and GitHub

*** UPDATE **  This event has been canceled.  Sorry everyone.  We’ll be having Open Hack night instead.

Interested in getting started with Git? Curious about what’s so great about this DVCS stuff? Have no idea was DVCS is? Join us for an awesome night of Git and GitHub and get bootstrapped. Jared from GitHub (@ShepBook) will be presenting and will be hanging around to answer your questions!
