UART in GPS navigation system With the rapid development of GPS (Global Positioning System) techniques, GPS gets wider application in many fields. GPS has features such as high precision, global coverage, convenience, high quality, and low cost. Recently, the use of GPS extends speedily from military to civilian applications such as automobile navigation systems which […]

This project primarily consists of four units: Microchip Technology’s SST89E54RDA-40-C-PIE, a sensor unit, an ADC0804 ADC component and the LCD module. Along with detecting an obstacle, its exact distance is also calculated and displayed on a 16×2 LCD interfaced to the microcontroller. The IR receiver detects the IR radiations reflected by the object being measured. […]

Attendance in colleges is generally paper based which may sometimes cause errors. Taking attendance manually consumes more time. So the proposed attendance system uses RFID technology to take attendance. In this system, each student is issued an RFID tag. Controlling unit is in the institute. Whenever the card is placed near the reader, it will […]

Universal Soft shell connectors MATE-N-LOK from company TE Connectivity belong to the best, what can be found on the market. In industrial applications we need various connectors. “Various” usually means really various -almost indefinite amount of types, to have a hope to find the right type for our application in a given series of connectors. […]

Description The MAX44005 integrates 7 sensors in one product: red, green, blue (RGB) sensors; an ambient light (clear) sensor; a temperature sensor; an ambient infrared sensor, and an infrared proximity sensor with an I²C interface. This highly integrated optical sensor includes a temperature sensor to improve reliability and performance. The IC computes all the light […]

This is a bandwidth monitor using a Raspberry Pi and an OLED display to graphically show the internet bandwidth into and out of our house.A video showing it working is above. Sometimes if the internet is slow or not working very well it can be hard to tell if it’s because three other people are […]

The acronym of the GSM modem is Global System for Mobile Communications, it is a wireless communication module, used to  make a computer or any processor to communicate over a network. This modem uses a variation of TDMA(Time Division Multiple Access) and is the most commonly used of the digital wireless telephony technologies like TDMA, […]

After receiving one IN-8 tube from a friend (thanks), I decided to build myself a clock. This clock is more an ornament than a useful machine because it consists of just one digit (tube) so it displays current time every minute for three times. It is built inside of an old wooden box and it’s […]

MIT researchers have developed a circuit design that could make simple superconducting devices with zero electrical resistance much cheaper to manufacture, and which would be 50 to 100 times as energy efficient as today’s chips. Even though the circuits’ speed probably would not top that of today’s chips, they could solve the problem of reading […]

Freescale Semiconductor today introduced the FXTH87 tire pressure monitoring system (TPMS) family, which is the smallest integrated package TPMS solution available at an extremely light weight of 0.3 grams. The FXTH87 family is 50 percent smaller than competing products, helping designers reduce overall bill of materials costs. Freescale’s newest TPMS system-in-package solution provides low power […]
