This paper explains the project which is a special kind of circular rotating 8 LED display. With the help some mechanical assembly, LED count, hardware requirement, and hence overall cost is cut to very affordable price and power is also saved. Also, maintenance and repairing of the display is so easy, that anyone having a little electronics knowledge can take care of this. All the synchronizing can be implemented through software. First of its kind, made using the 20-pin 8051 series microcontroller, this project use the principle of Space Multiplexing. This propeller display is mechanically scanned and displays the characters in digital format. Made from scrap it can be used anywhere and everywhere and the most amazing fact about this display is its crystal clear display. This display consists of just 8 bright LEDs which are rotated to show the display. For building this project, requirement is just a small 20 pin microcontroller, a position encoder, and LEDs. This display can show the messages, which will require a whopping 525 LEDs. So hardware and cost minimization is achieved and power which is required to run the 525 is also saved by using rotating 8 LED display.
