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.
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:
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 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.
