Retrobrad Presents! A Flying animation on a spinning LED display.

[TheMadHatterKing]

I want to touch it *_*

[hitruput]

brilliant. really cool display!

[avalableusername]

Thats awesome! You could play full-resolution mario on it!

[gollumondrugs]

What MCU are you using?

[gollumondrugs]

I like, I like!!!!

[blackjef5]

wow, seria genial tener un videojuego asi =D

[legoclockfreak710]

wow!!!! amazing!!!!

[digas200]

can u send me the scematic?

[saundysis18]

This is rather cute and excellently done :) Well done :) Love it

[garzonimpleks]

why this remember me river raid?

[seba9364]

U should sell this stuff dude!

[sasindu8vegas]

please sir can you give the circuit diagram? please

[deathwish001]

It sounds off balanced.

[00retrobrad00]

@deathwish001 Yep, it was quite off balance = )

[Caleb5617]

its even got the airplane sound lol

[SuperHaloslayer123]

just saying i think the switch should not be on the project its self otherwise greate idea it is cool

[00retrobrad00]

@SuperHaloslayer123 The problem with this version is that I used batteries for the actual display.

My new version transfers power to the board so there is no need for a separate switch!

[SuperHaloslayer123]

@00retrobrad00 o i just saw a switch on the side and i thaut it was the power switch and didnt see that the power switch was not on the project its self.

[Ramix09]

i love leds

[SuperFlight88]

1:00

[aminevich]

hmmm...3 people are obviously colour blind! Nice work....very creative

[00retrobrad00]

That's a fantastic idea!

Add loads more LED's and program in some multiplayer games - maybe even tetris or something like that.

Also, I have had a bit of a dream to build your second idea. Although you would need to be in some sort of perspex sphere otherwise you could get seriously hurt!

thanks for your comments = )

[AllFractUp]

It'd be sweet if you had one of these as a dome where differently positioned players could play from the one display. Head-to-head or a mixture of single player and one-on-one, two-on-one, etc.

Would it be possible to make a spherical version where the player(s) sits inside and sees the LEDs all around them?

[MusicGaming1]

is it using a microcontroller?

[DemonGirl91311]

thts soooo cool

[jhonilson]

very good work!.

Congratulations.

[harris3693]

is it possible to play porn on it?

[knabbers]

@harris3693 probably, but the images wouldn't be very sharp

[ufoengines]

I get a real kick out of this led stuff. Have you talked to the Narrow Band Television folks? Your design looks like a 2010 version of the old 60 line mirror screw monitors used in the 1930's on the mechanical television systems. However your display is in living color. Cool!

[MaghoxFr]

A question, does this represent any advantage than making 1/3 cirumference 8 pixels high led screen? I mean less energy consumption, easier manufacturing. It looks cool I'm just asking!

[00retrobrad00]

@MaghoxFr I guess the advantage of this version is that you only require 8 LED's (rather than 680 if it's going to be 8x85) so it's quite cheap to make and also you don;t require all of the interfacing circuitry to scan through 680 LED's

[MaghoxFr]

@00retrobrad00 thanks, I'm jus curious, love elctronics but I'm a total ignorant about it, your videos are really cool. I'd love to make stuff like that...I can't even fix my broken radio sadly, maybe I take its repair as a project and learn something off it.

[silverpizza100]

BS man you can buy these , You are just hacking into one. Fucking Liar!

[00retrobrad00]

@silverpizza100 Thanks for your comment = )

[silverpizza100]

@00retrobrad00 You Welcome! Jerk!@$% lmao

[rmvvwls]

@silverpizza100 Haha, you're a genius! I wish we were as smart as you!

[kallisti05]

@silverpizza100 lol, it's pretty obvious he built it as there is tons of proto-board there. Troll.

[ivanjesik]

Is it possible with strong laser lights?

With strong laser rays?

[firetammer6]

hay this would b cool if u did your mario game in this for like a spining screen

[PiratesWorlds]

this look great nice projekt, can you send me the construction plan please, thanks

[00retrobrad00]

@PiratesWorlds You can get all the details from my electronics website wwwdotbradsprojectsdotcom

[Ipodman72]

looks good

[happygamestvfun1]

i can make one without using and prebuild intergrated circutis liek u have made the whole thing out of...

[DelGeeZee]

do you have to stay within a certain RPM for the image to stay clear?

[00retrobrad00]

@DelGeeZee You do need to have it rotating at a certain speed, but the exact speed is not important. You just need to make sure you have a position sensor so you start drawing the image at the same spot each time.

[skilovermike]

ok. thanks



[skilovermike]

yeap. i've seen somethink on ebay to do that...cool. now...where i can find the sketch of the board? :D

[00retrobrad00]

@skilovermike You can get all the details to make this project on my website wwwdotbradsprojectsdotcom

[00retrobrad00]

@TheGhettoRepairman Yes, although at the moment it is a little time consuming to put them on, It would be great if I had a computer program that could let me manipulate the data to form an animation that I can copy straight onto the device.

[skilovermike]

how did you programed that think? you need some other board or connected to the computer?

[00retrobrad00]

@skilovermike It uses a PIC microcontroller. To program it you just need to get a pickit programmer (costs about $30) the programmer connects to your USB port and then to five pins on the microcontroller - the you can upload your code = )

[mmarandola3]

thats sick dude

[medicwine]

Use this to play super pixel brothers?

[00retrobrad00]

@medicwine It's funny that you mentioned that because I have programmed in Super Pixel Bros, I just need to get a wireless controller happening.

[bignp1]

EPIC

i hope you complete it it will be the most epic tang in existence

[changchung]

This remember me a intellivision game with a airplane, I dont remember the name of the game...

[itwa5me]

so cool!!!!

[nukearts]

just a idea from brainstorming: put the viewer inside the middle of the device and realize a 360° view?

[00retrobrad00]

@nukearts That would be a cool looking display! If it were 2 metres high or maybe a bit more and you have 1000 LED's then you could probably play some pretty cool games inside the thing!

[bocatablanco]

Do you have the schematics?

[00retrobrad00]

@bocatablanco yes, just check out my website for all the info you need to build this project. Also, I will be uploading details of my new one chip POV that does everything that this one can do, but uses just one chip.

[turf7227]

This made an idea pop into my head. Make one similar to this(maybe a few more LEDs) and instead of a single image, have a computer(maybe connected via an Arduino?) and a simple paint program on your computer. You then draw an image on your computer, and as you're drawing it, the data is sent to the Arduino, which then analyzes it, and sends it to the POV machine. Basically, the POV is a display.

[nukearts]

@turf7227

put the viewer into the middle of the device and make a 360° view?

[SagginWillies]

Just a thought, but is it possible to use smaller led's, and double your total amount? Like if you wanted to increase the resolution for a sharper image.... kinda like having more pixels in a LCD screen.

[00retrobrad00]

@SagginWillies Yes you're right. Even if I used LED's half the size and put them in the same space (so I would have 16 LED's) it would make the display look loads better. I just haven't been able to find any smaller RGB LED's unfortunately.

[SagginWillies]

@00retrobrad00 What type of programming do you use to display the image? can it handle animated gif's or mpeg?

[LilSayo]

Nice gadget! Plus you can make a salad with this thing! Just cut the vegetables!

[ChemicalComedown]

This is such an amazing project ! ! !

5***** ; )

[knabbers]

hey ive just made something like this, but i dont know what type of sensor i cud use (like ur one with the nail) that would be fast enough to respond to something like 10 revs a second. what sensor did u use mate?? btw i still really love it!

[00retrobrad00]

The sensor that I have used will work just fine at that speed (and even faster) I just took the led / photo diode sensor out of a computer mouse. I then connected it to a transistor so that if the light was shining into the sensor it would turn the transistor on which would give you a logic 0 at the collector output. then when you break the led / sensor connection it turns the transistor off giving you a logic 1 at the collector output.

[knabbers]

that's REALLY good! and cool

[vanjastanic]

OMG that was awsome!!!!

[rohonghosh]

super.. this should be really big some day if not tomorrow

[oraqol]

What kind of microcontroller(s) do you use? I don't suppose you can use the arduino for something like this huh?

[00retrobrad00]

I am using a pic for this project but you could certainly use arduino to make a pov display.

[fronkenpoop]

Great build. Excellent.

[Mutumaniac]

Dude! thats awesome!!

[raxxar69]

that's awesome dude

[MrRevolt10]

this thing is actually legit

i made a video review of this and some other similar stuff so check it out if u want more info.

[databang]

I like the concept and LED action. I don't like how the electronics look sneezed on :P

[00retrobrad00]

he he, yeah - that's what happens when you have a glue gun lying around...

[RsWeChanged]

epic!

[worldwar470]

oh my god thats to good dude

[dubhippy]

man i wish i could build a nice POV system like this. i've never so much as built a speaker crossover though.

[tempranight]

You need a sensor for initial position and another for final position. That's the way to avoid the image side-moving due to rotational speed variations (acceleration)... (I think).

[TheIVImann]

nice!!!!!!!!!!!!!!!!!!!!!!!!!!­!1

[KarriKoivusalo]

Nice! The first thing I thought seeing the animation was it would make a really kick-ass novelty '1942' video game :D

[spudhead96]

It also makes the sound of the plane. ;)

[00retrobrad00]

he he, yeah it's unbalanced and kind of scary at times.

I will be making a safer and updated version sometime hopefully soon...

[TeamNES1]

Sweet!

[Tchnclfl]

Simply stunning. How long did it take you to create the script for all those colors ? :O!

[00retrobrad00]

Thankyou very much.

I had a friend make an excel spreadsheet for me where I just drew one large image (which was about 85 pixels wide x 180 pixels high)

Then the excel spreadsheet converted the picture data into a hex file which I could then load onto the eeprom.

So all this does is scrolls through that one large image and then repeats itself.

I'd like to make a better one of these (when I get the time...)

You should see the one that some guy made of a globe with hundreds of LED's!

[diomaiaal]

super cool project...

[OahuLargeScaleTrains]

I love it, quite amazing.

[Pacmanghost]

you sound like chase from house

[muietumuie]

W...OO...T....UR MY IDOL DUDE SO COOL

[matthewm0311]

How hard would be to produce images in full color?

[matthewm0311]

wow lol

[Greenpeace82]

: D Genius.

[ICanConfuseYou]

:-O

[mon3104]

ok got it at the end ;)

[mon3104]

wow! is the animation the whole 360 degress or only from one side?

[Duxasblt]

a fan and a video game, awsome

[skierplaterandy]

WOW! that is amazing! best pov i have seen yet!

it looks soo good, i am truly amazed by this, especially because it is only a prototype.

[imgood009]

You are amazing with that instalation!!!!!

[bigobrother123]

dude if you make that game i'l give a 1000 bucks for it

[littleims10]

is that a cat purring at the beginning???

[Briglair]

holy shit.... that is... im speechless

[ranasingh]

super super cool, how about fixing wifi on that, having it connect to ur computer, write a computer program to output display to that

[xOxSainTx0x]

thats soooo fucking kool man!! can you make a beatbearing?

[AllFractUp]

Very cool. When will the 32 RGB version be ready? What would it take to recreate my fractal videos or fractal still on something like that?

[00retrobrad00]

Hi, I finished the 32RGB version but had a couple of problems with it so I went on with other projects. As for the fractal videos - I am not sure how to write a program that would convert them into the hex code required by the POV. but i guess it could be done as long as it is within the 32x64 pixel limits.

[ahmedebeed555]

Very good work. Can I put a link of this video for explanation purpose for a competition of a similar idea ?

[00retrobrad00]

Yes that is fine, I am glad that my project can help others out!

I hope the competition goes well = )

[ahmedebeed555]

Thank you very much. : )

[ovidiupatronu]

good job man !! do you have to program every pixel or you can use a software to help you out?

[00retrobrad00]

Hi, I had someone write me a simple excel program that allows you to draw pictures, it then converts the pictures into hex which you copy onto the eeprom = )

it made it really simple to make the animations!

[Limnoc]

That;s really cool. I like how the image is executed perfectly in a seemingly still box.

[00retrobrad00]

Thankyou = )

you should have seen how much it moved around without the sensor - it was all over the place!

[133MHzz]

The display is really sharp & steady, good job!

[00retrobrad00]

Thankyou very much for the comment = )

[JaimeDuende00]

WTF¿¿

YOU RE A GENIUS

[antiguerra]

which microcontroller did y use ?

[00retrobrad00]

Hi, i used a pic16f648a micrcontroller for this project.

If you want more info - feel free to have a look at my projects website, it has all the details you need for this display.

[vastylervas]

this technology would be sooo useful (maybe i should say cool) if it was energy efficient and a little quieter.

imagine news tickers or even ads in a downtown area. it would look awesome, but you'd hear whurring everywhere! lol.

awesome animation job btw.

[frollard]

You can have electric motors near-silent - this is just a budget job obviously ("prototype")

energy efficient? the leds use TINY energy, and if you kept the weight down, and put it in a vacuum cylinder there'd be almost no resistance.

[vastylervas]

oh wow that'd be cool. i was talking about the sound of the thing whirring around, like the wind, not the motor. but i'm sure up high you might not even be able to hear it.

now the problem of birds flying into it haha.

textured casing could fix that though haha.

[frollard]

again, if its protected by a bell-jar with evacuated air, nothing would fly into it.

[richedwards79]

Ever since I first saw PoV displays being used for clocks about 15 years ago I've wondered why they're not everywhere; back then I certainly thought they would be by now. The applications are endless - you could have PoV advertising displays mounted on the roofs of cars, buses and buildings, clocks, calendars, news and stock tickers, club lighting rigs etc. Obviously these would all have to be on a larger scale and be fitted with perspex enclosures to prevent any contact with the armature.

[00retrobrad00]

I agree, I have seen large scale versions of these with millions of colours and they look really good. They arent very expensive to make either.

[AlchoholicSnake]

Nice!

[dabomber1300]

thats cool

[conoba]

I am surprised how many people still use THT.

[00retrobrad00]

Hi, what is THT?

[Sine1040]

Trough Hole Technology vs Surface Mounted.

For the one who doesn't want to mess with cad software, chemicals and magnifying glasses TH is still the way to go.

It may be a bit dated, but who cares, some things you build on a piece of raster board before the computer had time to boot.

[ElGatoLoco698]

that's so F'n cool. I've been dabbling using LED's nothing even close to that though.

[SAMBEULINK]

wow kool

[Random1800]

wow, very smooth looking, good job!

[DrunkenGolfer]

excellent !

whatever you do, tho - watch the balancing !

[00retrobrad00]

Yeah, this prototype is very unstable but i have made a new one that has 32 RGB LEDs and it is nice and balanced. the only problem with it is that it has a bit of random 'static' that i haven't been able to fi just yet.

[its967kevin11]

nice job man, thats all really kickass

[Tr0tim]

Woahah. Please don't stop working on this.

[sheenafan]

thats real art

[e4g1e1]

THATS SO AWSOME!!!!1!!!!!!!!!1!!!!

[PixelOutlaw]

This is really AWESOME!

You might be able to make a horizontal scrolling arcade shooter with this setup. Maybe something like a very simple Gradius or R-Type style game. I think with a reasonable price and some dressing you could easily sell these with some games. The last thing might be to think about the life span of the system. I like to program arcade shooting games myself so the mention of a classic caught my attention.

[scaleop4]

love it.

[leeam2k]

no entiendo como llegamos a descubrir cosas como estas

qe bueno

[cowana2000]

Hi.

I want to make my own, but I am concerned about speed. I guessed 15 rotations per second would be needed for it to be clear.

15rps=900rpm

900rpm=66ms per rotation

66ms per rotation = 24ms per 130 degrees

=0.28ms per column. This sounds much too fast to read eeprom, load to outputs, pulse the latch and repeat times 3. Can you guess how fast yours turns, or tell me what pauses you use either during columns or between columns?

Many thanks,

Andrew

[00retrobrad00]

You dont need to worry about the speed at all. Infact I dont even know how fast mine spins and I didn't even work out what my delay between the drawing of each column is!

All i did was built it - guessed a delay and then spun it up. If the delay is too short then the image will be quite small (because it is flashing too fast for the motor speed) but if the delay is too long then the image will widen.

When i first turn the motor on the image is small (slow speed) then it widens as it speeds up.

[cowana2000]

Are you able to tell me what delays you did use in the final event? What speed resonator does your PIC run at?

The reason I am interested in timing is that I wanted to do it using a PICAXE PIC (bootloader, coded in basic). The problem with that is the code is slowed down - at 4Mhz you get about 1ms per command - when over clocked to 16Mhz this drops to 0.25ms per command. I am wondering whether I can do this project with picaxe, or whether it will require raw PICs and assembler.

[Cube8]

When you find a way to eliminate the need for separate batteries, will you please tell it here??

[mast3rbug]

Under 20 RPS, you will not have good result. I sell (Made) virtual clocks since 3 years on ebay

The best is 25-30 RPS

[00retrobrad00]

Sorry for the very late reply but if you goto my website (just check out my channel to get the address) and then goto my newer 64x32 pixel pov project, i have pictures and details there of how i got the power through to the rotating boards.

hope that helps.

[chrix2]

Nice, looks very smooth. Do you draw all 3 colours every rotation or every 3 rotations?

[00retrobrad00]

Thankyou.

I draw the colours every rotation. The eeprom loads up the red 74373, then the green 74373 then the blue 74373 and then once they all have their info - the outputs will be enabled which means the LEDS will turn on with whatever is laoded into their respective 'memories'

[jumpfroggy]

Looks great! What's the RPM? And are those 5mm LED's? I'm considering making a monochrome (green) POV display for my carpc mp3 player. The display tracks very well, no wobble. You used an optical detector for the trigger sensor? I want to drive mine by PC, so I'll need to figure out a way to get serial through the brushes/contacts.

Good work, looks great!

[00retrobrad00]

Thankyou.

Sorry but im not sure of the exact RPM (i just set it to a speed that gives me the best image)

Yes, they are 5mm RGB Leds (but surface mount would be better i think).

I know what you mean about getting signals through brush contacts! It's quite a challenge and one that I havent been able to figure out yet... make sure you let me know if you get yours working!

[NaagLugYaajUaSi]

Try Infrared remote control.

[jumpfroggy]

That's actually a great idea... You could have an IR receiver on the rotating side, and a ring of IR LED's on the stationary side. Then just pulse a serial code to transmit data. So then you just have to figure out, is it more reliable (less noisy) than brushes? And then, how fast can you transmit data?

Interesting idea...

[00retrobrad00]

I think that would be the best way to go. It would be quite interesting to see how the circuit responds to infrared signals when it is rotating... I guess you would want to send a pulse train of maybe 3bits? 000 = up 001 = down 010 = left 011 = right 100 = A button 101 = B button 110 = Start 111 = Reset The more i think about it - the more i think it would work quite well. how quickly could you transmit 3 bits = )

[NaagLugYaajUaSi]

how much RAM does it take to do all the frame? I have the basic idea of how to build one, but i couldn't think of any way to organize or reused my RAM.

[00retrobrad00]

This is where it could use improvement - because it is not very 'memory efficient'

It uses a 27E512 EEPROM (64 kbytes)

Each individual column (of 8 leds) has a red component a green component and a blue component - so it needs 8+8+8 = 24 bits (or 3 bytes) per column of data.

Each 'Frame' has 85 'Columns' so - 24bits x 85 columns = 2040 bits (or 255 bytes)

finally - 64k / 255 = 255

Therefor it can fit upto 255 'Frames' of animation in one 64kbyte eeprom.

[databus64]

How do you get power to the rotating electronics?

[00retrobrad00]

At the moment i am just using batteries.

I am working on some kind of brush / contacts system so that it wont need batteries (and will also reduce the weight of the rotor)
