The Small Tennis Computer Device on Wristband

Tennis, one of the most popular sports that offer over millions of dollars to the winners, has been the favorite sport for over billion of fans in worldwide. Based on the history, tennis was invented between 1859 and 1865, when Major Harry Gem and his friend Augurio Perera developed a game that combined two elements together: A racket and the Basque ball game, pelota. The world’s first tennis club had founded in Leamington Spa in 1872 and the very first tennis tournament has been held in the grounds of Shrubland Hall on July 23, 1884! If you’re a loyal tennis lover, and you can’t live without it, maybe this small tennis computer device on wristband is the fantastic gadget that you must have! When you’ve putted on the tennis computer… Continue reading

Measure Your Blood Pressure is as easy as ABC!

We’re living in the 21st century, where everything is moving in very fast pace. Hence, most of the people in nowadays are being threatened with lifestyle diseases, such as depression, obesity, diabetes, high blood pressure and so on… Talking about the high blood pressure, one out of three Americans is having the risk of getting high blood pressure, due to the imbalanced diet (High sodium, low potassium diet). Honestly, those people who got the high blood pressure didn’t seem to realize about it, until they’re getting stroke and paralyzed all the sudden! Hence, for checking whether you’re free from high blood pressure or not, you can simply do it by creating an automatic blood pressure meter! This automatic blood pressure meter is specially-designed, which is used for measuring the systolic… Continue reading

Tiny Guidance Engine – MSP430 16-bit Ultra-Low Power Microcontroller

Tiny Guidance Engine or it also known as “TGE” is a device that provides a flexible platform for guidance and control of Unmanned Aerial Vehicles, Autonomous Underwater Vehicles, small munitions and other applications. Tiny Guidance Engine becoming even more powerful in present days, as it combined with GPS receivers and control attains a level of accuracy. Do you know that TGE is the smallest, lightest and lowest cost solution that available on the market? Honestly, we can adapt the TGE to all airframes and weapon systems, which need precise control for any miniaturized, autonomous products! For your information, the project uses the MSP430F149, MEMS inertial, magnetic sensors and a GPS receiver. This Tiny Guidance Engine can be acted as a general purpose guidance engine, for either military or commercial. MEMS… Continue reading

The Cheap But Useful Ericsson Cell Phone Display GA628

You used to have an Ericsson Cell Phone GA628 and you also loved it very much, however after few years of using, you’ve decided to change a brand new cell phone and you just threw it inside the drawer and never touch or look on it after that? Well, instead of leaving it in the drawer, why don’t you reuse it and give it a nice little modification here? This project wouldn’t cost you too much, as it is a cheap and power saving simple display for battery powered, thanks to the help of Ericsson GA628 display. Since it’s a readily available and the I2C interface allows the connection to a very small microcontroller as well! The GA628 display will provide a 12 character alphanumeric display, where some of the… Continue reading

MSP430 TeHuMet project

Dubravko Gacina have sent a link to his project that was participating i a circuit cellar MSP430 design contests some time ago. This is a digital temperature and humidity metter based on MSP430F413 microcontroller. MSP430 microcontrollers are known as ultra low power MCU devices that are ideal for battery operated devices. Sadly that there is no more information including circuit and firmware. Also you can go through other projects that took place in design contest like Tiny Guidance Engine, Automatic Blood Pressure Meter • Tennis Computer and other projects based on MSP430 microcontrollers. You might find some great ideas for your own design. Continue reading

Handheld pocket health monitor

This health monitor may become a dream of many people while it is capable to monitor most of human bio-signals including ECG, EMG, GSR, Pulse Oximetry, Temperature, Breathing sounds and even movement with 3 axis accelerometer.   This health monitor is based on Texas Instruments MSP430 MCU which is characterizes as low power microcontroller. Data is sent via blue-tooth to Pocket PC where data is analysed and displayed as graphs. Also data is recorded to dataflash for backup. Continue reading
