A few days ago I was stuck in one of those YouTube loops (happens once a month) and I came across this awesome video on the Prince Rupert's Drop by SmarterEveryDay (Excellent channel BTW). About 3:00 minutes into the video they use something called a Polariscope to check out the stresses built up inside the Prince Rupert's Drop. Watching that I realized that I had all the things needed to build this at home.
You need the following things for creating a Polariscope :
1) A polarized light source (White in color preferably) - Since almost all LCD's use polarized light to display images you could use your iPad or Laptop screen displaying a white image. I went for my 22" monitor as I needed a bigger surface.
2) A transparent object - Not all objects work well for this as some don't really have that much stress.
- Things that work well - Glass statues, use and throw forks and knives, glue sticks, etc.
- Things that don't work well - Soda bottle…
Its been about 2 weeks since i posted anything.So here are a few updates.The quadrocopter design is finally complete(well sort of) and so is the flight computer. The sensors (Wii Motion+ and Nunchuck) are here. They seem to be working. The ATMEGA328 (Arduino based) which is the main component of the flight computer also arrived about a week ago and worked flawlessly.
This is all pretty cool but the main news is that I've finally ditched the name CPUV because i realized it sucked and now im going to name (Warning : Star Wars reference coming up) it "The Force". The flight computer is called Luke as it shall bring balance to the Force. Any more Star Wars references are welcome. Ok now that my moment of insanity is over , here are the designs:
Right now I'm building the pyramid (reminds me of my very first blog post) on top of the quadrocopter.I might try to change the ring i used for the base to something smaller when i actually start building the landing gear but this r…
Over the last year I have been working on the renovation/remodeling of my hotel in Nainital. Now we had a 1600 sq ft. area that was to be converted into a small restaurant for the hotel guests. Being a huge fan of LOTR I decided I wanted the entrance to the restaurant to look like a the door to Bilbo's house obviously with our own twist.
Here are some pics of the build.
The door is a two panel design completely circular and 7 feet tall. Its 1.4" thick and each wood panel weight in just over 50 kgs. Wood: Sagwan.
The hinges were made from 0.25" thick mild steel and cut using hacksaws and files
We still have some work left for the interiors and the tables and chairs and i post t
