sodnpoo.com has reverse engineered a cheap smartwatch he found on amazon: I noticed this smart watch on Amazon for the bargain price of £7.51, which was just too cheap to ignore - I didn't expect much but I was quite surprised at how functional it actually was... Anyhow, it was...

righto.com has reverse enginnered one of the most popular proccessors: How can you count bits in hardware? In this article, I reverse-engineer the circuit used by the ARM1 processor to count the number of set bits in a 16-bit field, showing how individual transistors form...

LUX Meter project has been design to measure the illumination. Illumination is luminous flux falling on surface area of photo diode. This illumination converted to corresponding voltage using Op-Amp circuit. Specifications Supply 9 VDC PP3 Battery @ 20 mA Onboard Photo...

Spirilis @ 43oh.com forum would like to monitor his woodstove temperature profiles so he build a plugin board for LaunchPad using the MAX31855 thermocouple to digital converter. This BoosterPack is fancied as a baseboard plugging underneath the LaunchPad, with four holes for...

Classic AC 230 V Timer project can be used in all application requiring a timer of up-to 3 Minutes to operate or control any AC mains load of up-to 200 Watts. This project is based on the Classic 555 Timer IC, triggering a TRIAC. Input and Output is Optically...

Subhan95 @ instructables.com has written a tutorial on how to use ESP8266 with Arduino and tweet using it. What can the ESP8266 do?It is limited by your imagination.I have seen projects and tutorials on the internet showing how to fetch a city's temperature, stock prices,sending and...

Well, Christmas may over but we think you may take a look at this well designed PCB Christmas tree and why not consider building it for the next year. Since I already have an Arduino, and I felt pretty comfortable with it, I decided to use it to control the LEDs. However a full...

Zhiyong Hao and Zhuo Chen from Cornell Univercity build A PIC-based Alarm clock system that is different from most alarm clocks known. This project is aimed to design a ‘Sleep and Wake-up Assistant’. Different from a normal alarm clocks which can only make noise, this alarm...
