Vero-Boarding [Software]

April 11, 2012

No matter how good your project is, how good a circuit designer you may be or how much thought you have put into your project, if the final circuits in your project are not sturdy enough, stable enough and strong enough your project is bound to fail. Electronic projects start from an idea which turns [...]

AVR Fuse-Bit Fixer [Gallery]

April 8, 2012

The Doctor to my AVRs, introducing the AVR Fuse-bit Fixer / Resetter. This is actually a High Voltage Parallel Programmer and High Voltage Serial Programmer built into one circuit with code to automatically reset any AVR connected to its terminals to factory settings. Details of AVR Fuse-Bit Fixer

Dual Power Supply [Gallery]

April 4, 2012

In first year of engineering, we were taught about rectification of ac signal by diode and how to make a simple power supply using step-down transformer for decreasing the voltage level of mains, diode for rectification, capcitors for filtering and voltage regulators at the end to regulate the voltage to some proper level. Until I [...]

Tachtastic – AVR Tachometer

April 2, 2012

“Tachtastic”, a not so creative name for a tachometer. I was in my 2nd year of BE at the time and making a Tachometer seemed like a good idea and an easy project (according to a senior). For those who don’t know, a tachometer is a device which can count the number of revolutions/rotations of [...]

Selection Menu for Text LCD [AVR]

March 28, 2012

An option-selectable-menu on a text LCD using an AVR is not such a big deal, but having it sure saves a lot of time as such a menu can be quite helpful and useful in many projects. Here’s a video of the simulation: I first made the menu for my AVR Tacho-meter project (AVR Tachometer [...]

Killing an AVR (or ARDUINO)

March 26, 2012

While working with AVRs, a few chips have been the unlucky ones who have died at my hands. I have damaged and completely killed(made dead) chips by giving over-volatge, sourcing too much current or simply by breaking away a few legs (including the VCC and GND legs). One-time, the damage was only done to one [...]
