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).
- More Raspberry Pi tutorials
- Working on the Telepresence Robot.
- Continuing work on the Battlebot
- Heater building (hey, it’s cold man!)
- Hex (the Robot) demo’s
- Hopefully there will be some quadcopters roaming around tonight too.
- Fun with barely legal electronic cigarettes!
Look for our sign out front and see you tonight!
I’m learning about Quadrotors, Tricopters, Hexacopters, and other multirotors and I have noticed that there are a bunch of acronyms, terms, and definitions that I don’t know. This is typical when learning any new hobby. So this post is simply a list of those acronyms and terms along with a few photos and definitions. I will add more as I come across them. Feel free to leave anything I missed in the comments section and I will add it to the list. Click on More to view the entire list.
ARTF – Almost Ready to Fly
BEC – Battery Elimination Circuit
BNF – Bind-N- Fly
ESC - Electric Speed Control
GPS – Global Posistioning System
FC – Flight Control Board
FFF – Fast Forward Flight
PNP – Plug and Play
RTF – Ready To Fly
RTH – Return To Home
RX – Receiver
TX – Transmitter
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.
- Telepresence Robot – The basic design is down, wireless ipCam – check, steering mechanism – check, motors to power the wheels – check.
- 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.
- Jeff will be coding in python and C.
- Continue building the Prusa 3d Printer.
- Robot Building / Heater building – Miles is building a kick-but battle bot!
- Much fun usually surfaces real time so we’ll see what else is happening.
