Magic Magnifying Glass by LED MATRIX 8x8

About: LED addict with Microcontroller At89s51/52 and arduino

Development of the existing microcontroller has been very fast. A lot of electronic equipment exploits microcontroller. One other applicable at microcontroller that is making the application of physic for presents character by using dot matrix led display 8X8 (8 column-8 line) common cathode. Basically, dot matrix led display is alliance some led integrated forms a number of columns and line. There is many type dot matrix led display sold marketing, usually which differentiates is a number of columns and number of the lines is and commonly made in network dot matrix led the display for example matrix 8x8 common anode or common cathode, matrix 8x8 common anode or cathode, matrix 8X8 common anode or common cathode.

From the angle of physical of people might possibly make it from single led, strung up with the certain order based on its and common what applied. For character physic application program bases on microcontroller AT89s52, I apply to a programme of assembly MCS51. For this time I will combine between dot matrix led display 8X8 with a magnifying glass. As we know magnifying glass can make the shadow bigger and to set the focus. Lets the magic begins...

Next, please compile the software through this link programming software

You will get a file hex after compiling the software, send it to microcontroller at89s52 by DT-HiQ AT89S USB ISP. Here is the link burning hex

Connect the microcrontoller with the previous schematic by using 5 VDC power supply.

Step 4: Final Step

To get the perfect shadows, put the LED Matrix 190 cm from the wall. The distance between the first magnifying glass and LED matrix is 7 cm. And 4 cm from the first to the second glass, also for second to third glass.

What we get :

1. The 5 mm LED becomes 60 mm

2. The 6 x 6 cm LED Matrix becomes 71 x 80 cm

To make it readable, the texts should put in upside down and mirror position.

Electronics, as well as software and hardware, is my passion. I believe that there is a way to simplify the
electronics (possibly using a shift register and/or to make it possible to control more 8x8 led matrix), but I need to enhance my knowledge. If you have any ideas that either simplify the electronics or make it possible to add more lights for each controller, please let me know in the comments.
