Introduction: Persistence of Vision (POV) -2 Ways to Play-

Picture of Persistence of Vision (POV) -2 Ways to Play-

After tired of searching POV tutorial that doesn't clear and complicated, finally I found the best one. In this instructable I will be recreating a POV (Persistance of Vision) Wand inspired by amandaghassaei's original design.  When I first saw the instructables I immediately wanted to recreate it with my own version.

The motivation of making this POV are because I want to make a light stick for my own. My first plan is want to bring it to the "Girls' Generation World Tour in Jakarta" Concert. But I didn't bring it on that day, hahaha Because of the colour of my POV are green. And the crowd all were pink. LOL

amandaghassaei's original design are made with acrylic. I'm using readily available parts without a deep knowledge of electronics one can begin to explore creating their own POV. I do not have 3D printer so construction will be done by way of PCB etching. And the difference are I'm going to make the POV can be used with two ways to play, easy to hold, and can spinning on the platform.


Ok, let's get started !!

Step 1: Parts and Tools

Picture of Parts and Tools

Here is all you will need:

(1) Arduino UNO R3
(20) LEDs Super Bright (I'm using green, my fav color)
(20) 100 ohm resistors
(1) PCB / Perfboard
(1) 9V battery
(1) on-off switch
(4) Spicer 0,5 cm
(4) nut and bolts
(1) Project enclosure (I'm using "Kitchen Ware" box)
- Breadboard
- Shrink tubing
- Rainbow wire
- Male header extended


Tools:
- Soldering iron
- Solder
- Mini drill
- Pliers
- Cutter
- Helping hands (if you don't have it, you can build it from my helping hands instructable)


** If you want to make your POV spinning too, you need to jump right intostep 11to know what all you need **

Step 2: Write the Code

Picture of Write the Code

I just a beginner of Arduino so I got the sketch from amandaghassaei's instructables. Download the POV code and upload it onto your Arduino board.  If you have trouble uploading be sure that nothing is connected to digital pins 0 and 1 and that you have selected the correct board and serial port under the Arduino/Tools menu.

Replace the words HELLO WORLD with any message in all caps with no punctuation. You can create your own characters and images by generating matrices of 1s and 0s.

Step 3: Making the Board

Picture of Making the Board

A PCB can be made by many methods like UV etching, toner transfer method, using a CNC mill etc. We’ll be doing it with manually way because the circuit is so simple, and doesn't necessary to print it. it’s the only method which doesn’t require access to expensive equipment/materials.

Step 1
Cut the perfboard, about 22 cm long and 4 cm wide. (see image 1)

Step 2
Draw the circuit line with permanent marker. I'm doing it  (see image 2)

Step 3
Etching time! There are a lot of "How to Make PCBEtching" out there, so I won't explain it again in my instructables.

Step 4
Drill out the holes on perfboard with a drill and a small drill bit. Be careful when using a drill. (see image 3)

Step 4: Making the Circuit on Breadboard

Picture of Making the Circuit on Breadboard

Let's build it on breadboard first. First, lets put the components on a breadboard so we could see how it worked and how to fit it onto the perfboard. The circuit diagram was made with Fritzing.

Test the 20 LEDs to make sure they're shining bright. You don't want to pull out the LED after they're already attached on perfboard.

Step 5: Move to Perfboard

Picture of Move to Perfboard

Step 1
Arrange the resistors. Each resistor is connected to an LED on one side and ground on the other. (see image 1)

Step 2
Bend one of the leads of each resistor so that they are touching each other and solder them all together in a row. (see image 2)

Step 3
Arrange the LEDs. (see image 3)

Step 4
The cathode (-) of LED connect to resistor, and solder them together. (see image 4)

Step 5
Solder the anode (+) of LED on perfboard. Clip the excess metal from the leads.  Leave the last lead unclipped so that it can be attached to a wire later. (see image 5 & 6)

Step 6: Wiring Time!!

Picture of Wiring Time!!

Step 1
Attach wires to each of the LEDs on the perfboard.  As you solder each connection, clip the excess lead off the end of the LED. (see image 1 & 2).

Step 2
Using shrink tubing is essential to prevent shorting. (see image 3)

Step 3
Solder the end of each leads, together with male header (extension). Be careful when you soldering the wire and the header, make sure they didn't touch each other. This will be connect to arduino. (see image 4 & 5)

Step 4
Strip both ends of a (preferably black) wire and connect the unclipped resistor lead, this is gonna be a ground. Solder it together. (see image 6)

Step 7: The Enclosure

Picture of The Enclosure

Step 1
Drawing the pattern on the lid with marker for placing the spicer for Arduino. It's really helps for drilling. (See image 1)

Step 2
Be careful when you drilling the "Kitchen Ware" Box, because it made of plastic. It easy to melt if the drill get hot, but it's okay you can tidy it up by using a small cutter knife. Put the spicer 0,5 mm. (See image 2)

Step 3
Put the Arduino to fit with the lid (see image 3)

Step 4
Draw a pattern for on-off switch, a long hole for wires,  a long hole for insert the perfboard, and 4 holes for nut & bolts. Use a small cutter knife to make a rectangular cut, still be careful. (see image 4)

Step 8: Put All Together

Picture of Put All Together

Step 1
Drill the perfboard to attach the nut. (see image 1)

Step 2
Arrange the switch and the battery according to image 2

Step 3
Connect the battery and switch to Arduino. (see image 3)

Step 4
Put together the POV perfboard and Arduino.

Pin connections:

Top of perfboard
1                       Digital Pin 13
2                       Digital Pin 12
3                       Digital Pin 11
4                       Digital Pin 10
5                       Digital Pin 9
6                       Digital Pin 8
7                       Digital Pin 7
8                       Digital Pin 6
9                       Digital Pin 5
10                     Digital Pin 4
11                     Digital Pin 3
12                     Digital Pin 2
13                     Digital Pin 1
14                     Digital Pin 0
15                     Analog Pin 5
16                     Analog Pin 4
17                     Analog Pin 3
18                     Analog Pin 2
19                     Analog Pin 1
20                     Analog Pin 0
Bottom of perfboard

Step 9: Put the Circuit Into Enclosure

Picture of Put the Circuit Into Enclosure

Step 1
Attach the PCB with nuts to the enclosure. (see image 1)

Step 2
Tidy up the wires by inserting them to second long hole. (see image 2)

Step 3
Attach the on-off switch to enclosure. (see image 3)

Step 4
Put the battery into the enclosure, and connect it to the switch. I'm using "Foam Double Side Tape Adhesive" to attach the battery. (see image 4)

Step 5
Attach the wires to Arduino. And close the enclosure. (see image 5 & 6)

Step 10: Finish!

Picture of Finish!

You're just finish it right away. The enclosure it's make easier to hold and play it safely.

If you are too lazy to holding it all the time, you can choose the second option that I will give it to you. Just check out step 11 to make it spinning.

Step 11: All You Need for Making It Spinning

Picture of All You Need for Making It Spinning

This is a quick step to make your POV spinning. So here all you need :

- Platform from wood (see image 1)
you can build it with your own way, for me I just bought it on the market, and it's originally was a cutting board LOL

- 12V motor (see image 2)
I think it's the best choice, because you can run it from 3V to 12V, at 3 volts it only pulled about 20mA and it runs fairly slow, then you can tune your adapter to the speed as fast as you want, but I warned you 12V are fast enough to make your platform shaking like crazy.

- Pencil case from plastic (see image 3)
I'm using an old pencil case. We're going to use just one side.

- I don't know how to name it or it's called, it's just a bended hard plastic. so we can stick it with the perfboard horizontally. (see image 4)


Tools
- Drill
- Hot Glue Gun
- Cutter
- Foam double tape adhesive
- Gorilla glue
- Super glue

Step 12: Build the Platform Board

Picture of Build the Platform Board

Step 1
Drill the board. Customize the diameter to the size of the dynamo that you used. (see image 1)

Step 2
Drill the bended plastic 4 holes as the holes on the perfboard. (see image 2)

Step 3
As I said before, we're gonna use a one piece of the pencil case. Add a glue (gorilla glue) at the corner to attach the bended plastic. (see image 3)

Step 4
Soldering the wires to the leads of motor. Don't forget about the polarity. Then attach a little piece of board on the motor with super glue. (see image 4)

Step 5
Put your motor in the hole. Add some gorilla glue onto the little piece of board to attach the pencil case later. (see image 5)

Step 6
Use a hot glue to attach the motor with the boards. Just to make sure it doesn't shaking when it's run. (see image 6)

Step 7
Attach the pencil case onto motor. You should put on the middle. to keep it balanced. Attach the bended plastic onto the pencil case. And attach the battery with some tape adhesive. Attach the Arduino with some Foam double tape adhesive. (see image 7)

Step 13: Assemble All Parts and Finish It for the Second Time!!

Picture of Assemble All Parts and Finish It for the Second Time!!
Assemble all parts. Try the platform first. Give 3 or 4,5 volts from the adapter to make sure they spinning with balancing.

If it's all run okay, then congratulations you just finish the second way to play your POV. Yay!!

Okay then, don't forget to give me a feed back or advice because I'm just a beginner.

Have fun :D

pbansal1 made it! (author)2014-02-15

Thanks Faziefazie...I made it using your sketch and schematics.. :)

It worlds great...

Can you tell what refresh rates should we experiment...The words in at the current refresh rate of 1..makes it very difficult to read.

Here are the images of the project...

Great Instructable ...

faziefazie (author)pbansal12014-02-16

That's cool, congratulations you've made it!! I'm really sorry I can't give you the right amount of fresh rate, now I used the arduino for another project so I never try to change the fresh rate because the fresh rate is already readable for me. But If you are curious you can change it a little bit, start from 2 ms, and upload it. Then goes until you comfortable to read the POV. Good Luck and tell me how it goes :)

mantap Bro....

faziefazie (author)ysulaiman2014-02-02

Makasih banyak :)

alexdrew5858 (author)2013-10-31

this is really cool but as much as I'd like to remake this I don't have the money for the tools, and I like how you did it for SNSD (I'm a big fan).

faziefazie (author)alexdrew58582013-11-01

You can make it just with 8 LED with ATtiny microcontroller, it will more cheaper I think.

Woow, it's so great to know there are SNSD's fans in this site. From where do you come from? nice to know you :)

alexdrew5858 (author)faziefazie2013-11-10

I might be able to pull that off.
I'm from the U.S. but I didn't know about SNSD till an online friend in indonesia tolld me to look it up, but I haven't been keeping up with SNSD stuff for awhile.

Thank you so much :)

memexie (author)2013-10-02

Keren Mas, tapi masih kurang kecil yah ukurannya unk dibawa kemana2. Ayo kita bikin LED cube.. liat deh yg punya "chr". Salam dari Palembang :D

faziefazie (author)memexie2013-10-03

Saya bukan 'mas' hahaha... iya karena saya mau bikinnya 20 px jadi butuh 20 LED panjang totalnya juga cuma sekitar 20 cm kok, kalo mau lebih pendek lagi juga bisa, pake cuma 8 LED. Tapi kode nya juga bakal berubah banyak.

Wah next project insyaallah LED cube kok hehehe...

memexie (author)faziefazie2013-10-03

Hehehehe..Yaudah kenalan ya? Kenalin saya Mega :)
Btw, saya pernah belajar running text pake arduino, cuma kendalanya saya blm ketemu cara yg tepat supaya running text nampilin seperti yg kita mau. Jadi harus programin satu-satu. Alfabet okelah ada 26, nah kalo bahasa lain? Misalnya mandarin. Dirimu ada solusikah? Mohon bimbingannya ya kalo ada :)

faziefazie (author)memexie2013-10-03

Halo mbak Mega! saya fazie hehehe..

Hmmm kalo pengen nampilin karakter yg kita mau, emang biasanya ngeprogram satu2 sih. soalnya alfabet juga harus tetep di program secara matrix kan. mungkin link ini bisa ngebantu http://garagelab.com/profiles/blogs/arduino-scrolling-text-marquee-to-give-a-happy-christmas
