Maxi Huber sent in this HD projector build that he documented in a Youtube video. He purchased the kit from a German company. Looks like a cool project.

"The benefits from this projector are: The price is very cheap (499€) for an HD projector with DVI, HDMI (Playstation3 is working via HDMI!), S-VHS and many other conectors! The fans are very silent and the lamp costs just 20€ so the projector can run 24/7 without ever getting poor! I had a lot of fun assembling this product and painting it according to the colour of my home cinema! And the result is just amazing: it has a great, great HD picture and the assembling is really easy and can be done by everybody! Even if the manual at the website is not english, it is not a problem to understand it because it consists mainly out of pictures…!"

I need one of these robots to make me some coffee in the morning! Even though I a sure there was lots of prep prior to each mini scene this robot is actually very strong and flexible!

Thanks for sending it in Alex.

Playing music using steppers is lots of fun, we have seen lots of stepper motor music in the past but this Super Mario tune sounds very nice.

"The sound you’re hearing is coming entirely from the motors. The motors are screwed into some pieces of aluminum from an old project to help them resonate. I’m taking requests for other songs to play. Currently, the information for the song is stored on the Arduino. Plans for implementing a realtime MIDI stream are underway. Eventually I’ll be able to plug in a keyboard and play the motors as though I were playing piano."

This Greenbox project is a beautiful way to save energy. Not only does it dress up the charging area but it also saves you money. When the phone is removed the wall wart charger is electrically disconnected.

"As a design exercise, I have built a phone charging station that makes unplugging very easy and instinctive (with affordance playing a big role). So easy you don’t even notice it unplugs automagically. The design is made from cheap and available materials, and was a great fun to build on a rainy day. "

Thanks Alberto

Voice control is great when it works. This Voice Controlled Helicopter looks like it functions well but I guess they could have taken 10 takes at making the video where every command was recognized the first time. I can see this being the next big interface for all of the hot new toys in the coming Christmas season. Not sure it would be more fun than a Helicopter with a Shotgun mounted to it but it would be close.

The guys over at Geeky Gadgets made a cool looking Apple iPhone Dock from some Old CDs, you might remember the pencil stand that they made before. This is a great project since you probably have all of the materials at hand and you don’t need much in the way of tools. What would make it cooler is if the top CD had an apple logo burnt on it using a light scribe disk.

"To make your own you will need a Dremel, 11 to 12 CDs or DVDs, you will need 4/5 more disks than the height of your iPhone charging connector on the USB cable."

This Arduino Oscilloscope project is a great idea. For people that are getting into electronics having a meter is good but having a scope is great. With this project you can take your $30 Arduino board and turn it into a oscilloscope, it won’t show you great detail or very fast circuits but often times that is not needed.

"This software allows you to get a visual representation of an analog signal using Arduino and Processing. The resolution is 10 bits so this is not like a real oscilloscope but it is still pretty useful. It works by sending values read from the Arduino board (pin 0) to Processing through serial communication."
