Thoppigala is a computer game developed by Vectronics and according to my observations it is developed using Game Creators FPS Creator. I have demonstration version of Thoppigala game and it is totally based on FPS Creator models and FPSC Model Pack 5. The vendor (Vectronics) do model’s texturing part only. Demonstration mission available in this release (file version 1.0.0.0) is based on the FPSC sample mission and it’s level designing is in very poor stages. In this game, player use Tommy Gun (Thompson Submachine Gun) for it’s operations, but the problem is according to my knowledge Sri Lanka Army may never use Tommy guns for there operations and it is widely used in World War II and currently it is not in use. FPSC model pack 5 contains good weapon collection and I don’t know why designers may not use them for these missions. This game have lot of other problems, most notable problems are, Enemy AI : During the attacks, and all the others just choose some random direction to run in,

There are several variable zener diodes available in IC market, but in Sri Lanka it is difficult to obtain variable zener diodes. (For example LM431) So I build this circuit to get the functionality of Variable Zener diode. This circuit is based on two transistors and for Q1 you can use any general purpose NPN transistor and for Q2 use any general purpose PNP transistor. Using this circuit it is possible to get 3V to 25V (400mW) output. I use this circuit for one of my SMPS project (as a replacement for LM431) and it produces an excellent results.
