With this hack you will be able to Hack a Sigma Lens to operate with Canon Cameras. The lens being demonstrated is an older lens and the camera that it is being adapted for is a DSLR. The issue is that the signals from the DSLR for adjusting the aperture of the lens are not recognized by the lens. By adding a small microcontroller in the mix, the camera
While watching the video I was wondering why there was so much complex electronics for the AZIZ – LED Microscope Illuminator Project. I was thinking that a simple dial to vary the intensity would be all you would need. If you are thinking the same thing have a look at the video starting around the 4 minute mark. By having modes that allow you to spin lighting patterns and
These Rave Shade – LED Glasses look like a ton of fun. They are Arduino based and use 74HC595 shift registers to light all the LEDs. At first I though it was a silly design since with a PCB sitting on your face you would not be able to see anything. But later I saw the small circles that are cut into the board which allows you to presumable see
Want to annoy IronJungle? Tweet a bunch of commands to his Twitter Robot Hand! His hand is monitoring the Twitter stream using a Raspberry PI and will act on your commands (seen below).  “A Raspberry PI monitors the tweets to @OurCatDoor. The PI’s GPIO acts as inputs to a PICAXE 18M2 which controls five servos on a robot hand. You can control the “The Hand of PI” by sending
  Gregor “G-Man†Hanuschak sent in a tip about a fun looking project called the Smack Attack, which is a Steering Wheel Drum Kit (might be a product soon). You can now play along with the tunes in your car! The Kickstarter will go live very soon and has a goal of $200,000. With a product price of $150 and a early bird Kickstarter price of $99 I am
 Guitar tuners are quite common these days. Only problem is that they use displays or LEDs to indicate how the tuning process is going. Sam from J44 Industries made a guitar tuner that a blind person can use for a charity called Remap. His design starts with an off the shelf guitar tuner, only problem with this one is that it used LEDs for visual feedback. He used
Check out these 3D Printed Speakers, they have been printed with 2 different materials. This allows the design to have something that resembles a ton of square light pipes. With some addressable LEDs on the inside it sure puts on a show! Â “These speakers are composed of two components that are 3D printed simultaneously: 1. Flexible rubber base (Objet TangoBlackPlus) 2. Clear crystal-like protrusions (Objet VeroClear) The clear crystals
