I’ve been watching a bit of youtube lately and found some things that interested me. Numberphile is a channel where a lot of math gets done (e.x. Illegal Numbers, Why YouTube Views freeze at 301), and Computerphile is the same thing, with the same guy, but with computers instead.
I was browsing the interwebs and found a video by 1veritasium on how to make plasma using grapes and a microwave oven.
When a grape is cut nearly in half and placed in a microwave, plasma is produced. Please use caution if attempting this experiment: don’t leave the microwave on for too long, make sure the area is well ventilated, and stand back. Remember the contents will be very hot afterwards.
Recently when I logged on, I found that a massive queue of spam users and comments have been created. They were all deleted, but I have added a captcha to the login screen. When you log on, you will now also fill out a captcha to make sure you are not a machine.
Thank you all for signing up, if I accidentally deleted your account then please sign up again.
I was browsing the web today, looking for model rocket simulators. I found Apogee Rockets and looked at their software, RockSim. I thought it looked great, but thought it was a bit too expensive. Then I saw OpenRocket and thought it was great (and free)! I had a bit of a time using it, but it worked. Then I tried selecting a motor. Then I found out that Apogee Rockets has a chart which helps you figure out what engine you need. Handy!
Processing is an open source programming language and environment for people who want to create images, animations, and interactions. Initially developed to serve as a software sketchbook and to teach fundamentals of computer programming within a visual context, Processing also has evolved into a tool for generating finished professional work. Today, there are tens of thousands of students, artists, designers, researchers, and hobbyists who use Processing for learning, prototyping, and production.
» Free to download and open source
» Interactive programs using 2D, 3D or PDF output
» OpenGL integration for accelerated 3D
» For GNU/Linux, Mac OS X, and Windows
» Projects run online or as double-clickable applications
» Over 100 libraries extend the software into sound, video, computer vision, and more…
» Well documented, with many books available

Merry christmas! For christmas, I have created a program for the Arduino. It plays “Jingle Bells” on a 16Ω loudspeaker on pin 8. To download the program, go to the Downloads page and copy code for Jingle Bells for Arduino.
