Awsome Quad-copters at CCCamp

Check out a couple of the awesome quad-copters that have been flying around cccamp. I happen to be building a similar model in right now, except its a tri-copter. The lack of a forth motor throws in some funky corrections that need to be made by the uController. This means it probable won't be nearly as stable as the ones in the video, still just as awesome though.

SubZero Robot Update

I know it's been a while since I posted, but I have been incredibly busy. Anyway, I wanted to post some pics and info about the latest progress made on my robot. Basically, I got my new Laptop (a Dell Inspiron 1501) mounted in a nice foam coated box on the robots lid. Just below that, you can see the main navigational sensor, a WebCam from RadioShack. I also wrote some code in Python to take a snapshot from the WebCam, look for the center of the road, and decide if it needs to go left or right. Heres the Link to my Flickr account with all my robot pics.

Next Processor Develoupment: Marble Computing

Not Sure how I missed this one at first, but Make blog had a very interesting writeup on a 6 bit binary computer (powered only by marbles). It's amazing at how simple it really is (especially for those of you who think computers use nothing but electricity and magic). It'd be really interesting to see this implemented with 32/64 bits.

Workout with Pong

Hack-a-day has a post up about a guy who attached electrodes to his arms, and used to the electric impulses coming off his muscles to control a Pong game. I imagine you could increase the challenge quite a bit by trying to curl dumbbells and play at the same time. Link.

Is the Day of Silence Working

Wired has an interesting article about if the Internet Radio Day of Silence is working. The writer was able to get his hands on a few more figures than I could. For example, the new fees require a $500 minimum payment per month per station. With radios like Pandora, each user creates at least one station of their own. That means that it would be completely impossible for them to survive. Link.

The Death of Online Radio

Today marks the death of internet radio. Starting Midnight, this morning, thousands of internet radio site shut down. It is possible that they will eventually return, however, most will likely not. The reason for their death is the fee increases imposed by the RIAA. For example, "Pandora Radio" had their rates tripled (plus, those increases are 18 months retroactive). Thanks a lot Washington.

Can Gaming's Powerful Pull Get Kids Into Engineering?

In last months Electronic Design magazine the editorial was titled, "Can Gaming's Powerful Pull Get Kids Into Engineering?" It discusses weather or not products like the Hydra from Parallax can pull children gamers into the game development fields. Personally, I think it depends on the child. Link.

Who needs illegal immagrants to pick fruit?

With all the immigration debate going on, one company has decided to do away with laborers all together and build robots to do the work. They have announced that they are developing a fruit picking robot that can replace human fruit pickers completely. Somehow, I doubt it will work. Link.

C to D battery Adapter

Everyone has run into this problem: you need a D battery to power something and all you have are C cells. What do you do? Make blog has the answer. Link.

Wii Power Glove

Hack-a-Day has a nice writeup about the fusion of NES controller and Wii controller. Link.

I'm Back

After a very busy and not quite long enough trip, I'm back. Posting will now continue on it's normal routine. If you want to know more about my trip, you can view my account in flicker. Link.

Lack of Internet

I have long said that my only true fear is loss of internet access, lol. Well, since I've been in Alaska, this is the first that I have been able to locate one. I guess war driving does come in handy sometimes. Anyway, I'll try to post some stuff to night.

Nerd Bias?

I have heard lots of people debate whether Wikipedia is a reliable source or not, but today, some odd accusations came out. One website is claiming that nerdy topics (like light saber combat) are better written than non-nerdy ones. It seems logically true to me. People write about what they know, and nerds are more likely to edit wikipedia. Therefore, nerdy topics are better written. Link

Make a Trebuchet

Makezine has a video podcast up of how to build a balloon flinging trebuchet. Link

Going Away

As I stated in an earlier post; tomorrow, I am leaveing for Alaska. Because of the 12 hour trip, I will be unable to post many things. If possible though, I will post something during our layover in Phoenix.

MY CNC Router

My CNC router made some real progress today. For about 4 hours, I struggled to get an EDE1204 Bi-poler Stepper driver IC working. I finally gave up and decided to write a program for the Parallax Propeller to drive the stepper. Five minutes later, I had a working X axis. Its bad enough that I wasted 4 hours, but those stupid ICs (I bought 4 of them) were $9 each.

CNC Mill How-To

Well, once again, I've had lot of stuff to do today. All day today I've been down in the basement working on my CNC router. I designed mine, but if your interested in building one, there are designs all over the internet for them. One of the particularly good how-to's is posted on Engadget. Enjoy.

Too much to Do

Sorry about yesterday's lack of posts, but I was incredible busy. Summer vacation starts tomarrow, though, so I shouldn't be quite so busy.

Downloading Videos How-To

About a month ago, I finally decided to upgrade my mp3 player. I ended up getting a Microsoft Zune for several reasons, 1) it has the potential of running Linux (and becoming a small robot controller) and 2) it was cheap for a 30 GB player. On of the first challenges I faced was where to get video to watch on it. After a while I discovered an awesome Firefox plug in to help with this. Sorry, this only works for Firefox users.
1) Download and Install Video Down loader 1.1.1.
2) Download and Install Media Coder
3)After Watching a video on YouTube(or letting it fully load) , click on the VideoDownloader icon
4)Left Click to Save video (you must add .flv to the filename)
5)Use Media coder to convert from a FLV file to what ever file type you like/

I know it's not very detailed; but I thought it might help some of the people with Ipods and Zunes to get the videos they want.

Awsome Robot Snake

This has ought to be one of the coolest robots ever built. I can't imagine how much power the processor would need to have to generate movement that smooth. Just Pure Awesomeness.
