I was impressed with two articles on Instructables.com Magic-POV-Wand-yet-another-POV-toy and Persistence-of-Vision-Wand. They have explained in great detail, to build a LED POV and mostly display a name or a message.
I did not find just text very interesting ,So I drew some Alien UFO and Faces in Green.....
To Reduce form factor I used Arduino Nano instead of Uno
Step 1: What You Need ?
- Arduino Nano ( Bought on Ebay for 600)
- 19 Green Leds ( You may choose your favorite color)
- 19 100 Ohm Register 1/4 W
- Universal PCB
- 9V battery with connector
- 7 to 9 mtrs of soft wire
- Wooden stick
- Soldering Iron, FLux, wire
- Black Tape
Step 2: Circuit Diagram
The original Circuit was for 20LEDs, But on my PCB I had space only for 19 - 5MM LEDs
Same I adjusted in the code
Step 3: Build It
Select a universal PCB and cut into long strip, I could not put 20 LED so selected 19 leds as shown
Solder The leds and 100 Ohms registers as shown, or refer the Circuit diagram
On another fix the female connector for Arduino Nano
Solder the wires as below images. Remember these are not easy and take quiet a long time. So take regular break
Step 4: Final Packing
I Covered the whole thing using Black tape
