The heart of the unit is CPU ATMega1280 microprocessor running at 14.7456 MHz (Y3 crystal). This frequency provides required accuracy to clock serial communications at 57600/115200 bps between the unit and external devices such as PC, GPS module, GPRS modem, JPEG cameras etc. The ATMega1280 processor has four hardware serial ports facilitating simultaneous interactions with […]

Here is a demonstration of LED Matrix Display project working together with DefendLine. It is worth noticing that a digital video camera makes the display visibly flickering due to slightly different LED display and camera sensor refresh rates. […] This article begins detail description of DefendLineII project and aims to simplify its assembling, setting up and further development by wide range of embedded controller designers and enthusiasts. First of all, traditional question, what is the purpose of designing a new hardware platform when there are a lot of things to choose from like Arduino, […] DefendLineII main unit PCB DefendLineII is the most advanced and multifunctional project of Magictale company so far. It was designed to be the second generation of DefendLine GSM alarm system allowing to break mobile phone dependency, aimed to minimise power consumption, increase overall system’s fault tolerance and remain fully functional in environments with […] Multipurpose LED Display PCBs These are just the PCBs for Multipurpose LED Display Kit, no other parts are included! You must supply the rest of the components to build it. To get more comprehensive information download LED Display User Guide $20 USD for item plus $8 USD for flat shipping […] Multipurpose LED Display KIT Multipurpose LED Display Kit is designed as elegant and simple addition to microcontroller projects. In comparison with conventional LCD displays which have already over flooded the global market it has significantly bigger symbols brightly glowing in dark areas and distinctly visible from a distance of a few meters. At […] New PCBs for multipurpose dot matrix display module have been delivered. Each module comprises of two PCBs joined together by a connector and allowing to minimise vertical dimension virtually to a LED matrix height and giving flexibility to change display color simply by replacing the LED panel. This time a different PCB manufacturer has been […] Needless to say that words are redundant in this particular case. 🙂 This video speaks to you itself by showing DefendLine system in action. DefendLine Kit DefendLine Kit is a fully assembled and ready to use PCB, it is an excellent solution for anyone from beginners to experienced hobbists, the device can be considered as an inexpensive GSM alarm with potential of sending pictures of a guarded site (the latter option is available for certain mobile phones […] DefendLine assembled main board At last all necessary parts arrived and the home made device reincarnated into a neat assembly based on factory manufactured PCB. The microprocessor has been flashed by means of USBTiny programmer via ISP connector and the system has been successfully tested – no functional problems. For more information about […] |
