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)
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)

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.

User Groups Mini-Conference: GREAT SUCCESS!

User Groups Presentations

The Buffalo Tech User Groups Mini-Conference: 2013 was awesome! There were almost 60 people in the room at the peak. We’re gonna roll this into something even better next year.

But, more importantly, make sure you got the calendar of events to come. This is a listing of just some of what’s happening in WNY in the coming month and further out. Download the PDF file here:

Buffalo Tech Meetups/Workshops March/April 2013+ [PDF]

Check out the list and find something you’re interested in, attend it, and support the things you want to see thrive. You can keep up to date on what’s happening by following the calendar on http://nextplex.com/buffalo-ny/calendar

If you missed the event, here’s a list of the presentations we had:

Hope to see you out & about at the coming events!

New Class: Beginners Electronics Part 1

basic_electronicsChris Cockrum will be hosting another class.  This time is for beginning electronics.

There is limited seating available so Please register if you wish to attend.  Wed, March 20th.

Part 1.  Ohm’s law and Watt’s law

This class will teach the basics of voltage, current, and power.  A lab will be included that will demonstrate how to calculate the proper value of resistor to connect LEDs to power.

Parts and equipment may be borrowed from the hackerspace or you can purchase a multimeter (http://www.harborfreight.com/7-function-digital-multimeter-92020.html), a few LEDs, a few resistors, clip leads, and a 9V battery for $5.    Alternatively, you can bring your own.

Basic Cryptography Course at Baltimore Hackerspace

Chris Cockrum of the Baltimore Hackerspace will be giving a course on Cryptography this Wednesday, February 20th at the Baltimore Hackerspace. He will be teaching the fundamentals of public and secret key cryptography including exercises on RSA, elliptic curve, and cryptanalysis using Sagemath (Python Based).

According to Meetup, the class is full but if you are interested in having another class, please let us know by leaving us a message on the meetup entry.

Baltimore Drones Kickoff Success

Baltimore Hackerspace hosted the first meetup of the new Baltimore Drones Meetup group. The event was a huge success. There were about 10 drones on display and everyone had stories to tell and knowledge to share. One of the hot topics discussed was the perception of  the word Drones. Baltimore Hackerspace can relate to this problem. The word “Hacker” has been tainted for decades and our decision to call ourselves a Hackerspace vs a Makerspace was a big one. What is the definition of a Hacker anyways? Everyone has their own opinions of the word.

Baltimore Drones is in the same boat. What is a Drone? Should we call our toys Drones,  UAVs,  or Multirotors? This was a hot topic and we all seemed to agree on most things. There are so many positive things Drones can be used for. Most of which can create new jobs which are disparately needed these days.

Thank you to all who participated. We look forward to hosting future meetups for Baltimore Drones.

February 5th at openHack:

baha_logo_all-simplified_black_on_white178x180Here’s what’s going on Wed. Feb 6th Baltimore Hackerspace:

 

  1. Telepresence Robot – The basic design is down, wireless ipCam – check, steering mechanism – check, motors to power the wheels – check.
  2. Installing ‘Occidentalis’ on Rasberry Pi’s and connecting them wirelessly to a network. Continuing through adafruit tutorials. – Didn’t get too far with that last week.
  3. Jeff will be coding in python and C.
  4. Continue building the Prusa 3d Printer.
  5. Robot Building / Heater building – Miles is building a kick-but battle bot!
  6. Much fun usually surfaces real time so we’ll see what else is happening.
