RasterWeb!OK, I have to admit, I thought the Photojojo captcha was cute, clever, and fun, but if you’re not into photography, and are more of an electronics nerd… I have just the captcha for you!
I saw this one over on the Adafruit Blog and then found this post about it. And if you’re running WordPress, you can install the plugin and use it on your own site.

The Arduino is a microcontroller, but it’s better described as “an open source electronics prototyping platform.”
And what does that mean?
The term “open source” is usually applied to software, and in that context it refers to software that is free. Not just free to download, but free to modify as you wish. (There’s some distinction between “open source software” and “free software” but I won’t get into that here. It’s safe to say that both of them give you the rights to make changes to the software.)
As for the “electronics prototyping platform” part of it… That’s what it is. A platform for building things with electronics. If you’ve built your own microcontrollers in the past, the Arduino may not be very exciting, but for beginners, or people looking for a platform to build upon, it’s a good thing. (And the open source part makes it even better.)
So what can you do with an Arduino? Here’s a few ideas…
Those are just a few of the interesting projects I came across in the last week. There’s also a nice long list of Arduino user projects in the Playground, and I’ve started to collect Arduino links.
Where can you get one? Adafruit Industries is one place, Maker Shed is another, and SparkFun is another. (See the SparkFun Buying Guide.) If you’re just getting started, I’d recommend the Arduino Uno (which was just released in fall 2010.) Since the Arduino is “open source” hardware, there are also clones you can buy, and each has strengths and weaknesses… but if you just want to start playing, get the Arduino Uno.
Right now I’m just working through a lot of tutorials, writing test code, having a bit of fun, and thinking up some interesting project ideas… How about you?
Fritzing is an open-source initiative to support designers, artists, researchers and hobbyists to work creatively with interactive electronics…
Since I’m a n00b who can’t read schematics, the breadboard view is good for me… Lady Ada uses it in some of her tutorials.
So if you’re just getting into Arduino hacking and can’t read/write schematics, give Fritzing a try… you may get something like this:
Here’s my first attempt at a breadboard illustration. This is for a sketch that reads data from the photocell, and lights up the LED if it’s too dark in the room. Oh, and if it’s too bright in the room, it makes the piezo buzz. Pretty darn simple. I’m not 100% pleased with my illustration, but it was my first time, and since I’ve built this more than once, I guess it should be considered a success.
The Fritzing site has a list of projects and the application (and web site) encourage you to share your creations (under a Creative Commons license even!)
Oh yeah, as for calling myself a n00b, I took a number of electronics classes when I was in school (which was a long, long time ago) but I’m finally getting back into this stuff, and it’s exciting. More updates to come!
This is the “Net Neutrality” session from BarCampMadison3 which took place on August 28, 2010 in Madison, Wisconsin.
Aaron Couch led this session, and there’s some good follow-up to it on his blog and info on the new organization that grew out of this session, Net Neutral Wisconsin.
You can also download an MP3 file if you’d like. (And for our freedom loving friends, enjoy an Ogg file.)
Also, if you want to get all of the audio automagically downloaded podcasting style, subscribe to the feed. I’ll add in more BarCamp stuff as I get it all edited and published.
I’ve never been sure about publishing recipes, I mean, who holds the rights? But since people keep saying to me “Hey dummy! You can’t copyright/trademark a recipe!” I’ve decided to start publishing them…
Here’s my recipe for Pumpkin Chocolate Chip Cookies.
Ingredients
Directions
These cookies do not flatten out like normal chocolate chip cookies. They stay sort of puffy. They’re almost like a cross between a cookie and a muffin. A cuffin? A mookie? I don’t know… I find them delicious though.
It should go without saying that you should use raw sugar (not processed!) and unbleached flour (not “enriched” or bleached!) and any other more natural/organic materials you can find. But it doesn’t. So I’m saying it.
Enjoy!
