 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 the same time, unlike 7-segment LED displays, this solution is capable of displaying not only digits but chain of characters. What it remarkable, the message length is not limited by the display width due to scrolling effect which is implemented in software. All these features will give your project new, unusual look and may make wider its application range. The display is fully supported by DefendLine project but could find its application in any AVR/PIC based project; To get more comprehensive information download LED Display User Guide Features:
It includes:
$55 USD for item plus $8 USD for flat shipping 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 chosen, the order was placed with PCBCart company instead of Futurlec so now there is an opportunity to compare them. Both companies are located in China but PCBCart has fairly lower prices. It also has higher technological capabilities offering smaller minimal drilling sizes, narrower minimal traces widths and minimal clearances. Specialists in PCBCart work definitely faster without need of reminding about your order and asking about its fate. On the other hand, Futurlec offers cheaper delivery and very, very simplified PCB order quotation (the latter could be considered as advantageous or not depending on your qualification and/or PCB requirements). And finally, the visual quality of silk layer if slightly better in Futurlec (font quality is kind of same but long straight lines drawn by PCBCart are not that straight due to hardly noticed by naked eye variable width).  Multypurpose LED Dotmatrix Display PCBs 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 only). The board works in tandem with a mobile phone or a GSM modem. Apart from GSM guarding function this kit might be used for automation of many different tasks or to serve as a module for more complex systems. For more information please refer to the project’s description: DefendLine project PLEASE NOTE: The firmware contains user specific settings such as master phone number(s) for sending alerts to and for controlling the device remotely, sensor descriptions, mobile phone commands to interact with its embedded camera etc so you will need an AVR ISP programmer (for instance, USBTinyISP) in order to flash your device. Alternatively, you can provide us with your setting and we can flash it before shipment. In any case the controller is flashed with default settings and tested to make sure it works. Features:
It includes:
$32 USD for item plus $8 USD for flat shipping Status: END OF LIFE  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 this project please follow the link: DefendLine project  DefendLine PCBs At last first three DefendLine PCBs have been manufactured and delivered. Anxiously awaiting for components to be delivered as well to begin soldering. Meantime, if it is topical for you, please express your interest in PCB by writing a message to the admin. For more information about this project please follow the link: DefendLine project Welcome everyone to the newly created Magictale Electronics blog! As you probably already guessed, it is dedicated to exploration of vast, entertaining and everchanging world of modern electronics and particularly those devices based on microprocessors. The projects published here are thought to be implemented in a way allowing to simplify the understanding of their principles, take advantage of non-standard approachs and original ideas yet keeping hardware and software complexity below the limits of home laboratories and electronics enthusiasts without scientific degree. This blog is supposed to be useful not only for hobbyists but for professionals as well. Please feel free to comment, ask questions and suggest ideas. Good luck! |
