Sonny recently shared his current progress of his UAV Quad Copter project and included a test flight video.
So today I had my first real flights with my quadcopter UAV. The setup is pretty advanced and it takes a lot to get up to speed. I’ve learned a lot from my build. I made custom printed PLA motor mounts, which have worked out really well to hold them on the end of aluminum pipes. Unfortunately the cross in the middle which is also PLA could not handle the rough landings and cracked. I’ve secured it for the time being, but I think I’ll be milling something better Wednesday. If I can work out the stability issues, I’ll bring it Friday. Anyway, check out the first flight/set of flights.
Ben sent me this writeup of his progress on his Rep Rap Prusa printer. Here’s his progress using one of the teensyduinos that PJRC: Electronic Projects with Components sent us.
I am currently building a rep rap Prusa 3D printer and one feature I want to add is a Graphic Display to display the nozzle temperature and the heated bed temperature. Once I had the Teensy in my hands, I rummaged through my parts bin and found a 128×64 graphic LCD.
As an Arduino newbie, I was blown away how easy the Arduino environment is to get up and running. Within minutes, I was able to get the IDE installed and the Libraries installed for the Teensy.
Using the GLCD example on the Teensy’s website, I populated my breadboard. The Crystal Fontz LCD (CFAG12864B-YYH-N) I used in the project has the NT7107C driver, not the KS0108 found in the GLCD example. The pin out on the Display ended up being different, but worked just fine.
My plans are to use the I2C output on the GEN7 Prusa electronics to send the temperature data to the Teensy over the i2c bus. For prototyping, I used the “Bus Pirate” to send i2c commands to the teensy to simulate the GEN7 electronics.
This Friday February 18th at Republic Coffee we’ll have members showing off their Arduino projects and answering questions about the Arduino platform. We’ve had a lot of interest in getting started with various Arduino boards so come learn more about the great things you can do with an open source platform.
What is an Arduino? Arduino is a physical computing platform and a software development environment for controlling various things like motors, sensors and even entire devices. The hardware and development environment are open source and there is a very large community of developers and hardware hackers out there working on projects. The hardware is also quite inexpensive. There are also “Getting Started” kits that are a package of items to help you hit the ground running with your Arduino.
We’ve leased a space at 2203 Freemont Rd! We’ll be handing out keys to all paid members at the 12/17 Friday meeting at Republic Coffee. Google Maps: 2203 Freemont Rd. Memphis, TN 38114. If you are not yet a full member you can become one by paying dues for December. We’ll be discussing our initial move in plans at the meeting on Friday, we look forward to seeing you there.
The LAN party last Saturday was a great success, thanks to everyone that was involved in setup / clean up and a special thanks to our host, Jeff Leath and our very own Kevin Dunn for some really tasty chilli. Thanks to everyone that showed up even if you didn’t play, was great to see everyone.
Since we have a lot of tech members among our group I wanted to pass along (in case you aren’t already on the GOLUM mailing list) that some people are looking to revive the Group of Linux Users Memphis. GOLUM was started in the mid 90s and in the past years has faded away. There has been a lot of buzz on the mailing list the past two days about getting something started again. So If you’re into Linux in any capacity from absolute beginner or advanced professional, check out the GOLUM mailing list and see what the buzz is all about.
Also Thursday 7/22 is the July meeting for the Memphis PHP Group. I know we have a couple of members planning on checking out the meeting. The meeting is being hosted at Lunaweb on Park Avenue. See the site for more info and if you’re interested come check it out with us.
With all this happening don’t forget about us! We’re meeting every Friday night at 7pm at Christian Brothers University on Central. We’ll be in the Nolan Building room 241. We hope to see you there and bring you’re friends! The group has quite a bit of diversity, we’re not just a bunch of techies so anyone interested in making something is more than welcome!
