It’s been a blast yet we’ve been able to get barely 5 hours sleep. But we will get all this cool stuff posted.

Mayhem & Chaos brings you some really cool sit and pedal POV (Persistence of Vision) using recycled bicycle parts.

I guess Mayhem took it to Burning Man every year. Cool… I gotta go one of these days.

Thanks Mayhem for letting us take a vid!

Here’s a simple flying saucer oven that uses a single light bulb yet heats up to 425 degrees fahrenheit!

They won the Dorkbake competition. This is really simple but great idea!

Check out these Cool ALAVs (Autonomous Light Vessels) by Jed Berk! Tight! It uses Sun Microsystems SunSpot microcontroller, which can be programmed in Java. I like this idea since there’s a lot of Java embedded processors out there but this ones from the creators. Jed tells me that all the pieces were 3D designed on the computer and laser-cut, kinda cool~

Jed says, Make Store will have these cool DIY ALAV kits soon!

Internet is kinda slow here at the Maker Faire. (That’s why our posts are slow too.) We even switched to a Sprint Broadband but with live video streaming, it’s still too slow but we will keep postin’~

You can come and join us to chat here to while watching our live video.

You can also check out our Flickr photos from Maker Faire Day 1 and Jed’s Flickr for more ALAVs.

Hey we are live at the Maker Faire, blogging live! See our automated camera that follows people? Well, it’s a $160 Logitech camera we got in a hurry at Best Buy last night just before the store closed. Glad we got it working although the internet here sucks sometimes. Anyway, our booth is really popular!

Garrett is doing a great job with the crowd while I am hiding in the back. (Why am I hiding? Blogging of course!)

Here’s a very simple wireless keyless entry DIY using some relays and stuff, very similar to the Wiimote Door Unlocker.

The mechanism is simple enough, just a momentary button on the panel in my apartment, but the mess of wires in the wall is a little unsettling. I took some meter readings of the terminals and sorted out the door button wiring. You can see where the door button is soldered through the PCB, which made it easier to identify the proper terminals. This panel has a “Door”, “Talk” and “Listen” button. The “Door” button is normally-open and the circuit is about 22V. In the following steps we’re going to effectively bypass the button with our own circuit.

Wow, check out this cool DIY on how to make a rotating LCD! This IS very useful for reading PDFs and whatnot.
If you don’t want to make one or you are about buy a new LCD, there’s also bunch of LCDs out there that already rotates. (which I use at work)
CNET has a great review of rotating LCDs.

This fixture is very usefull for rotate 90 degrees the monitor in order to see o read documents in in a portrait fashion, there are drivers for video card that support this modes, in my case i use it to read pdfs.

Check out this cool supercharged airplane you can make in your free time!

The single-sheet paper airplanes you made when you were a kid (or perhaps last week in your cubicle) were, well, kid stuff compared to this beefed-up paper craft, which uses an electric motor from an old pager or toy powered by a big electrolytic capacitor. Known as a “Gold Cap” and made by Panasonic, the capacitor charges from a battery pack and then metes out a steady flow of power to keep your propeller whirring for about 10 seconds—just long enough to send the flyer airborne and carry it between 30 and 100 feet.

Wow, check out some of these really cool DIY Thumb Pianos!

Sometimes an instrument you know can become something else altogether. Bob Collier has been constructing his own thumb pianos, adding amplification, effects, self-sampling features, and novel cases involving recycled camera bodies and faux fur. As Bob says, “Sometimes the crudest and roughest looking kalimbas can sound surprisingly good especially with the right context of fx and
amplification.”

I find kalimbas beautiful and delicate to begin with. Throw in some faux fur and Korg KAOSS Pad effects, and they take on a whole new life:
