You can’t calculate binary values “as is” on most handheld calculators and using the windows one is just a pain, so i decided to make my very own (binary only) calculator. This calculator supports all the basic functions like : NOT,OR,AND,XOR, addition,subtraction,multiplication,division and modulo. So join me as we are going to enter the world of ones and zeros …

To get better UV expose, Andrianakis has built new Switch Timer that will turn of his UV exposure box after some time. The timer uses ATmega8 as main processor and two 7-segments LED as display. There are two buttons for set and start the timer. When time runs out, microcontroller switches relay and also sounds a buzzer. The time …
My microcontroller-powered prime number generator/calculator is virtually complete! Although I’m planning on improving the software (better menus, the addition of sound, and implementation of a more efficient algorithm) and hardware (a better enclosure would be nice, battery/DC wall power, and a few LEDs on the bottom row are incorrectly wired), this device is currently functional …

Introduction CalcParser is a command line calculator. Controlled by a serial connection, CalcParser parses and evaluates an arithmetic expression and has the capabilities to perform symbolic polynomial differentiation with respect to a user-defined variable. It can also evaluate the differentiated expression at a given constant value of the user-defined variable. High Level Design Rationale and …
Introduction: Due to the increasing need for securing data and places, the biometric authentication industry is seeing large market growth. We decided to build a scalable, small, and efficient device that can be used to secure doorways throughout a complex. We use a FingerPrint Cards capacitance based fingerprint scanner as our capturing device. This data …
