Controlling Spykee Via Web Cam Using Your Fingers

spykee

[epokh] sent in this cool project where he wrote some custom code to control the Spykee robot using gestures. He filters out everything but green through his web cam, then wraps his fingers in green tape. He then runs a series of filters to clean it up a little bit. The resulting “blobs” are tracked and converted to motor commands. You can see the setup in action in the video after the break. This guy might look familiar, as we posted a super quick head tracking rig he did with legos recently. Some of you mentioned, in the comments, that the legos were a waste, you’ll find that he thought so too, and ended up fabbing a simple rig to take the place of the legos.

Beat Boxxx And Speak To Me/Breathe

[Steve] is in the MFA Design and Technology program at parsons, and as part of his studies, has built a couple really interesting projects. First, the Beat boxxx, as seen in the video above, is an 80’s retro looking portable beat looper. You create and loop your beats at the time of playing using simple hand gestures. The look is great, for those who enjoy cardboard and magic marker, though we think some tonal variation and possibly a wider pitch variation would really make this fun.

His second project is Speak to Me/Breathe. This project was meant to be a commentary on security in our daily information. He is visually displaying the braille symbols to spell out his emails. If any person were to spend the effort, they could decipher his emails. The finish on this project is quite nice, you can see a video of the display after the break.

POV Pong

[Akeeh] posted something to our flickr pool that caught our eye. The image was a rotating POV display, playing pong. We followed through the links and found this very well done rotating pov display. The construction is quite nice, showing multiple colors and smooth motion. there’s a little bit of wiggle even though it has a custom round pcb. Maybe a little better counter weight would help with that. The idea isn’t new, but it is good looking and elegantly made.

Twittering Toots, A Chair’s Perspective

April 13, 2009 by Caleb Kraft 28 Comments

We might have to add a category of “stuff made to twitter”. The latest installment is an office chair that twitters whenever it gets farted on. The author has a smart sounding description as to why he decided to make this, and he has a pretty good point about twittering interrupting the things you’re twittering about, but it all boils down to the fact that he wants to twitter his farts. We can’t say that we didn’t expect something along these lines. He has mounted a natural gas sensor in his chair, along with a squidbee wireless transceiver. You can download all the code as well as see the construction in the instructable. You can also follow his flatulent adventures on the twitter account of the office chair.

[Daniel] sent us over to the blog for the Naval Academy’s Autonomous underwater vehicle entry for the AUVSI competition. You can follow along as they design, build, and test this years entry. It really looks like it would be fun to be the guy who gets to swim with them, like in the latest post in their blog. Their entry, named “Awkward turtle” can be seen above in orange, pictured with their 5th place winning previous entry.

Dell Mini 9 3G Install

[Rob] sent in his Dell mini 9 3G install. He bought the Dell without the 3G option, but found that he really wanted it. He installed a mini pcie bracket and found a sim connector that matched the specs he needed. Apparently they use one that it rare as it uses the first pin to indicate whether or not there’s a card loaded. He pulled the mini pcie 3G card from a cheap USB adapter. After soldering it all in place and firing up OS X, he was able to connect, without issue. He says the reception wasn’t great, so he’ll need to add an antenna. This is similar to the process seen on the Acer aspire one 3G hack. Since you’re already in there, you might as well add a GPS while you’re at it.

Googles Servers Revealed

We’ve often wondered what kind of hardware the giant of the internet, Google, used to handle it’s data. They’ve recently revealed what their main workhorses are. It’s a custom motherboard made by Gigabyte with two processors, and eight RAM slots. The main point of interest on these is the fact that each server and piece of network equipment has it’s own battery backup. This may add a little money in the initial cost of the unit, but apparently it is a much more efficient way of handling power. Be sure to click over to the site and check out the shipping container setup that they use. Each container has 1,160 servers. They aren’t the only ones using this method. Microsoft has adopted it for their newer facilities and Sun has done some extensive testing on how these portable facilities handle earthquakes. You can see the quake test after the break.
