LA Arduino Monthly Meetup

Let's get together to have talks, discussions and share our experiences with Arduino.

 

For this time we are going to have:

Leslie Brothers: presenting one of her projects called "Peepers".

"Peepers are shy creatures that poke their heads up cautiously when no one is near, but quickly duck back down when someone approaches.

A Maxbotics ultrasound distance sensor detects proximity, while smallservos with pulleys and springs move the creatures in response."

 

Typer Calderone: talking about a "Daft Punk Helment" that he is building.

"A custom PCB manufactured for this project. Each PCB has 56 LEDs on it, with 8 more outputs tied to a series of 4 LEDs (strips), for a total of 176 LEDs (two sides/PCBs). Each PCB is controlled via a max7219 7-segment display driver, which is in turn controlled by a single Arduino. The Arduino gets input from a mic, which I break down to read the spectrum of sound, to display on the 7x8 LED matrix, per PCB, while "scrolling" the 8 strips. Not completely done yet, but most of it's working."

Video / Demo: https://dl.dropboxusercontent.com/u/3098221/VID_20130423_214034.mp4

 

Harrington Joseph: explaining his current project, "A Robotic Arm".

 

 

We are still having room for more talks.

 

Formal Talks

30 minutes to 1 hour+ presentations and/or demos about topics, ideas or projects, Arduino related.


Lightning Talks

5 to 15 minutes of Arduino related topics. Screens or demos are not required, just come up to the front and share your project, ideas, experience, thoughts, etc.


If you would like to present, please send me a message with your topic.


Parking

There is underground parking below the facility. It's $6 to park there. You can also park around Main st.

    Hello everyone, I just received my bluetooth module for the Arduino and I was able to wire it and have the Mac pair with it without a problem :)

    I would like send/receive data from the Mac to the Arduino using the BT module. I tried PyBluez and LightBlue, but neither one installed properly on the Mac.

    Does anyone know of a python module (or any other language) that I could use to send/receive data from the Mac to the Arduino using bluetooth?

    Below is the link the the BT module I bought:

      If you have them paired already, does that mean you can send programs to the arduino from the Arduino IDE environment, over Bluetooth? If so then I would try using the same methodology in "run time" mode. I.E., try to open and receive data on that COM port. Make sure that your boad rates match. You can use "serial monitor" (Cntl-Shift-M) to test. and the Serial.write() command in your arduino program. I have not tried this myself yet. My Bluetooth Xbee was lost in the mail. :-< But I hope that this helps.

      Thanks for your response, James! The BT module is paired through "/dev/tty.linvor-De­vB" on my Mac and when I point the IDE to that port and match the bauds, I get nothing on the IDE monitor. I'm using the corresponding Arduino sketch from: http://stackoverflow....­

    Hey there again, just posted an article on my blog about my project, which includes some of the pictures and videos I presented, as well as the presentation itself. Feel free to comment and share, but note: it's my first post on my newly made blog, so there may be some errors with it. Otherwise, enjoy!

    Hey all, had a great time. Tons of brilliant people.

    As promised, here's a link to the GitHub page with my code: https://github.com/Tyr0/Guy-Manuel-Helmet

    The chip I used is a max7219cng (http://www.digikey.com/scripts/DkSearch/dksus.dll?keywordSearch&keywords=7219CN), the mic I'm using is a max4466 (http://www.adafruit.com/products/1063).

    My powerpoint is available here: [COMING SOON]

    And lastly, my custom manufactured PCBs were created using http://www.cadsoftusa.com/ and manufactured through http://oshpark.com/

I decided to start Reno Motorcycle Riders Group because I wanted to be part of a group of people who enjoyed my passion... I was excited and nervous. Our group has grown by leaps and bounds. I never thought it would be this big.
