Japan is studying whether to go it alone on building its next generation of fighter aircraft. Japan's ministry of defense has been working on the Advanced Technology Demonstrator (ATD-X) for four years and it's scheduled to fly in January. Nikkei Asian Review says the ministry is asking the government for $384 million to fund a test program designed to see if the ATD-X can form the basis for an indigenous fighter program.

A senior editor at IEEE Spectrum worked on a DIY project that enabled his 11-year-old son to improve his touch typing by use of a vibrating glove. His son was already "pretty quick on the keyboard," said his father, David Schneider, but his finger technique could have used some more training. Schneider tried making a glove to serve as a training tool. Eight vibration motors were sewn into the fingers of cycling gloves. He programmed the Arduino to activate a given motor for a quarter of a second corresponding to each character he sent to the microcontroller's serial port—"a "1" would vibrate the motor pressing on the left pinkie, a "2" for the left ring finger, a "3" for the left middle finger, and so forth." He had to write a program that could run on a laptop for his son to associate the stimulation of the fingers with the correct sequence of keystrokes. He chose Tkinter, Python's de-facto standard Graphical User Interface package. The program presented a word and showed the word spelled out on the screen. It sent the appropriate character to the Arduino so that the corresponding finger was vibrated.

I have seen there are some simulator available for basic Electronics devices like Pspice, Proteus, Circuit Lab.

They are providing simulations for the basic electronics parts like Controller, Resistor, Diodes, LCDs but I am wondering if there are simulators available for Power devices like SCR, Thyristor and similar?

Please share if you know about such simulators. Is it possible to use MATLAB for such simulation or any example available in MATLAB which can be used to simulate power circuitry....
