Thinking @ Speed of Light

I was just browsing around the internet and came across this video  which described how to make your own Makey Makey board using an  Arduino Leonardo . I had all the components laying around at home so I decided to make my own. Here is a video where i used 4 glasses of water to play some drums from  http://www.virtualdrumming.com/ . No I can't play music, well not right now anyway :-). The Makey makey is basically a circuit that converts anything conductive - even slightly conductive (Metal, Coins, Bananas, Humans, Coke Cans, Glass of Water, etc.) into a button on your keyboard. You connect a wire from the circuit to the object you want to make into a button (key). Connect your self to the wire from the circuit labeled "hand". Done. Now the moment you touch the object it will send a key-press (example 'a') to your computer via USB.  Using the Arduino Leonardo you can convert up-to 6 objects into a key at any given tim

I recently bought a a Lens Reversal Ring   for my DSLR. It is a pretty nifty gadget available at dirt cheap prices. The way it works is you screw it on the filter thread of your lens and then mount the whole lens to your camera in a reverse orientation. What this essentially does is it converts your lens into a macro lens lens (You can focus on things that are super close to your lens). Obviously there are some disadvantages to this approach rather than getting a proper macro lens. Firstly as your lens is mounted in reverse you don't have any control over the electronics (So auto-focus). Secondly, in case of canon lenses (in Nikon it closes down) the lens opens up the widest aperture (with no control) which can be a problem some times as you get a really shallow DOF which causes issues sometimes. For the second issue there is a workaround and it works (well sort of - alteast on Canon 600D and other similar cameras). Lets say you want to click a pic with an aperture at f

I've been learning how to play the guitar for a few now days. As customary I had to render out a 3D image of one (not the exact guitar I'm learning on) I downloaded the basic structure of a guitar form some site a few days back (I forgot the link from where). Anyways it was a simple low poly model so I had made a lot of changes to the same. Refined the whole thing. Did the texturing, lighting and camera setup. After that rendered the whole thing out (took about 20 minutes for each image as 4K). The DOF was added later in Photoshop as rendering it out was too tedious.
