Sharks with "Lasers"Microcontroller Monday: I2C
Monday night (Nov 10) I'll be going over the I2C protocol and how to make it work for you. I2C is used in all sorts of sensors these days, and understanding how to make the AVR's speak it is useful stuff!
I'll bring in some I2C external memory chips, a temperature sensor, and a 3-axis accelerometer. There'll also surely be steaming hot, AVR-to-AVR, master-slave action. After a little bit of lecture and some code demo, we'll see how many of them we can get working...

AVR Microcontroller Class: Columbus Day Edition
In honor of Columbus Day, the AVR class took a night off from "formal" instruction and messed around with noisemakers. Specifically, using analog-to-digital conversion techniques to control the pitch of a square wave run through a small speaker. Hilarity ensued. (Follow along with us at the
Microcontroller Class 0 a Success!
16 AVR programmer kits walked into a room in anti-static bags last night. 16 fully assembled and tested programmers walked out. Many people learned to solder and the sweet smell of flux filled the air. It doesn't get better than that.
Except that next week, it will.
Special thanks to Mitch for the cool demos, soldering coaching, and endless enthusiasm.
If you couldn't make it last night, don't fret. The course will run again at a later date.
Head on over to the wiki for class notes and downloadables.

Syllabus:
Each class will be about 30 min introductory lecture, 20 min lab, 20 min lecture, 20 min lab.
Patches for Lab Coats
What a brilliant idea, sewing 2D barcodes onto patches that re-direct to specific (and changeable) URLS ! The thing that amazes me MOST of all is that you can snap the p8tch with an iPhone and some software to decode this. WOW !
Door Unlockerator Project
Last night, Ash came to the meeting with an RFID reader and a couple cards and an idea to turn it into an automatic door locker/unlocker by hooking it up to a motor and a small microprocessor. I liked the idea enough to toss it up as a project.
The reader speaks 2400 baud 8N1, so it's a piece of cake to interface, and the cards are only $1.19 each.
POV Laser Projector - First Proposed Project Up!
I've gone forward with a relatively simple project, check it out, if anyone feels they want to be a part of this, have any comments or extra galvos and lasers(insert Dr. Evil pinky grin here). E-mail me: eric@hacdc.org
Let's see how fast we can get this over to Ongoing Projects!
Check it out.
