Solar Calculator

  What is efficiency ? Fill factor ? These things are measurement of solar panels how good they are. This is my flash based solar calculator. It can calculate the efficiency and the fill factor of a solar panel for the given values.  I have created this calculator to try out flash. If there are m

Interfacing CMOS static parallel RAM with a PIC

Interfacing CMOS static parallel RAM with a PIC

This circuit is to increase the RAM memory of a PIC microcontroller using a parallel RAM. The address of the data byte can be accessed or assigned by serial in parallel out shift registers. From this the number of I/O pins from the PIC can be minimized.

External Parallel SRAM with PIC microcontroller for beginners

External Parallel SRAM with PIC microcontroller for beginners

There are instances where we can not use SPI flash memory or non-volatile memory module since they are very slow in writing and reading and they can only operate write cycles to a limited number. This post is to introduce about interfacing a SRAM to a PIC microcontroller and communicating with it.

Battery Charger by hysteresis method

  Here is a battery charger circuit for 12V car battery. In this method battery will start to charge and stop at 13.8V , after the battery voltage goes below 12.2V it will start charging and repeat the same process. This is a simple hysteresis where the output will depend on the previous st

Solar energy is abundant but still we are struggling to produce energy at a high cost and high price for the world. In future the world we know would be different from now as I know. The solar cells would be history and new innovations that could extract sun’s energy directly without any wast would be possible in future. We must adjust to that gradually so every one will live happily for a long time. We are still like frogs in a well thinking that we know everything around us. If we can just get out of the well and explore a bit around we can find many more great things that can be helpful for our lives. But many of us like to stay where we are like frogs as we all know for a fact and only one or two try to go out of the box and try to find new things. Yet the finding may be dangerous or may be harmless but we use them for meaning full things rather than using them for fighting for material needs.   Mobile users also can view this site but some menu and flash contents will not load properly due to minimization.Web browsers like Internet Explorer, Firefox and Chrome are tested and can be used to view this site properly.
