Kerry Wong has built a great Laser Oscilloscope using two Speakers. Of course this is not something that can be used to measure any real voltages or waveforms with any accuracy, for that you can use any used $50 scope. What this one does is produce a great visual display. You would be able to record separate right and left audio tracks to produce any light show you like.
If you are interested in making a very basic scope to monitor some simple things before you spend the money on a real scope have a look at the work that vaupell posted in the Element 14 community. He tried a number of internet scope projects until he found this one that worked like a charm. “After trying many different versions of code and tutorials, I was unable to

If you are into minecraft you will soon be able to use some technology to interact with the game using physical objects. Adafruit is making this possible with an NFC reader that they will be releasing soon. “Coming soon to the Adafruit Learning System, a project to make paper Minecraft blocks that interact with the game on a Raspberry Pi using NFC (near field communication)! Swiping a block
Birds are amazing. We have recently seen quadcopters that are allowing us to take virtual flight but nothing can compare to what birds do naturally. Check out the world record flight of this eagle from the tallest building in the world. The short video is above and the full length one is below. When the eagle sees the handler and starts the dive he sure gets up some impressive
If you are looking to build a large low resolution screen stringing a bunch of WS2811 LED Strips together might be just the thing. ejunky66 shows us how you can make a cool flexible DIY LED Display using WS2811 LED Strips. The strips are stuck onto a plastic sheet, they are linked together in small grids that are then connected to the computer controlled interface. This panel won’t be
RFID technology has rapidly been getting cheaper and simpler for the DIY enthusiast to get into over the years. The video above uses a Raspberry Pi and doesn’t have build instructions but that doesn’t matter much. Any microcontroller can easily connect to the heart of the access system which is the actual RFID reader. An Arduino could be used instead, it could be made stand alone instead of network connected
