64 RGB-LED color wave table (Arduino, 12x TLC5940)

[4090snand]

Dear Santa.....

[comehoot12345678]

Looking atdubstep ... and ended up here .. WTF ?

[Nullatrum]

What happens if you eat it?

[interactivefurniture]

A low cost "power supply" made in china. I've used a couple of capacitors to make it work.

[phishinphree]

What kind of power supply did you use for this? I'm having problems with excessive ripple with the power supplies I have tried in a similar 16x tlc5941 project

[mistaecco]

It would be interesting if the parts changed along with changes in temperature or weight on the tiles. Cool!

[MrZazhy]

why 12 times tlc5940?

[mrinvader]

wavetable synthesis?

[MrThraen]

lol, at first i thought my eyes were playing tricks on me, but then i read the description and realized it IS moving :D

[DarkAvatar1313]

you should program a mode for it to flash colors fast like a miniature 70's disco floor

[j03Biz]

Did you buy or build that table? I just want to know where you got the tiles from.

[kewldude81]

Love it

[bestamerica]

'

how about 4 color lights are better than 3,,,

4 colors are blue, green, red, yellow

[rekcaHrepyH]

@bestamerica yellow = red + green.

[bestamerica]

rekcaHrepyH,

'

it is okay and not too bright enough,,,

only one yellow is better

[sanosukke]

Very cool project, but I have some questions, why control each LED individually instead of multiplexing them? BTW, did you daisy-chained all the TLC5940? If so, how's the frame rate? I got 4 of those chips from TI and was wondering if I could drive them in parallel.

[interactivefurniture]

@sanosukke haven't thought about multiplexing two years ago. take care, they are very damageable.

[alidrongo]

Hi there, I'm trying to build a similar installation for a wall, what did you use for the boxes to diffuse the light and get neat squares?

Thanks!

[interactivefurniture]

@alidrongo just wood, nothing else. :-) 

[anthropreneur]

Dude, have you put this on instructables yet?

[interactivefurniture]

@anthropreneur sorry, did it right out of my head, no plans, no schematics

[madshusted]

how did you connect the 12 TLC5940 to the uP? and is the 3 lags of the RGB connected to etach output of the TLC5940?

is it posible to get a schematic ? and a software ekxampel how to control the TLC5940?

[ekhamburg]

@madshusted arduino.cc - i havent got any schematics, sorry

[holycrapapie]

SHUT UP AND TAKE MY MONEY!

[mkultra2300]

really nice work there 

[ketse89]

Really nice, but is the color variation between same color colums on purpose, or just because of led manufacturing variations?

[ekhamburg]

@ketse89 in the first table version (this video) I'm using cheep LEDs with the result of those differences. now I take a couple of SMD-LEDs in each segment - no variation any more.

[rekcaHrepyH]

@ekhamburg I think the colour variations look nice.

[SnickersHunter]

That was very cool man, hope to see more projects with microcontrollers.

[gonsuarezcba]

nice work, it looks awesome!

my suggestion is that next time you should try to multiplex the outputs of the TLCs, you could have done exactly the same with only 1 or maybe 2 TLCs!

[interactivefurniture]

@gonsuarezcba you are right! ;-)

[Harani66]

nice build, very impressive. what do you use to diffuse the LEDS to get such an even colour spread in each box ?

[interactivefurniture]

@Harani66 no diffusor - just wood and glass

[ekhamburg]

thx to everyone! :-) im realy happy to see all those nice comments!

[80srockzz]

only 1 word is appropriate: amazing

[turnavies]

I may just be too impressed with how well the slow fade works as a non-obtrusive animation, but it's unclear to me why you would put 12 TLCs in this table.

Why not sink 8 RGB columns (x3 for R, G and B leds) through 24 PWM outputs of 2 chained TLCs and multiplex or shift the anode rows?

[ekhamburg]

@turnavies it is way more powerfull for further applications... but u r right, thats a way too

[roAdKiLL013]

Lol for a second there, I fully thought the table had started to fold, because of the camera slightly moving. Haha tripping balls!

[neosystopia]

Welche RGB LEDs hast du dafür genommen, superflux oder ganz normale 5mm?

[ekhamburg]

@neosystopia normale 5mm rgb

[Techlur]

Did you just use standard LED's for this? How many LED's in each box?

[ekhamburg]

@Techlur std 5mm rgb - one for each box

[ekhamburg]

please send an email - we can talk about a rebuild.

[MrDobilina]

@ekhamburg you shouldmarket this, get a glass top to it. I would get a diy kit of this!

[postmodernbrain]

Beautiful table. Where can i buy one. Name a reasonable price. I

[glimpsefb]

Hi!

Really great job!

Have you ever tried with more TLCs? I'd like to make such a table, with 100 RGB LEDs so I'd need 19 TLCs. Do you think it's possible? TI says that it is possible to daisy-chain 40 chips, but I'd like to know if someone has already done this before soldering all this stuff :)

Thank you!

[SigSharpeSolutions]

@glimpsefb It sure is possible. I'm working on a TLC5940 project myself at the moment and I'm posting videos of my prototypes. The next one I post (Prototype #3) will include 3 TLC's and a clean circuit layout. I was running into some issue with power when adding on TLC's. You'll need a dedicated 5V power source for the TLC ICs, and you'll need to make sure the power source has adequate current. I'm currently using a 12V 2Amp power source... the circuit is nice and happy now.

[00retrobrad00]

This is such a great project! You've inspired me = )

[willeb96]

Go to the beginning of the video and then press RIGHT ARROW when you are at the end press LEFT ARROW, continue, continiue and continue!

[1000und1led]

Nettes Teil!

[takitsu]

aaweesoomee! if I had that, i'd stare at it all day o.O

[Paxmax]

LOL! awesome job, the table is beautiful.

22 thumbs down on this video?? what?? must be some jealous people.. pfff..

[mrmeval1]

While that looks like it took a lot of time. This video is very boring.

[TVTransform]

@mrmeval1 Yeah but I do want one. I do agree with the video being boring maybe a time lapse?

[mrmeval1]

@TVTransform It is cool. I just picked up an Arduino Mega to complement my Arduino. NG and as soon as I get an updated atmel chip for the latter I'm going to be doing an RGB wall with some glass block.

[PatMan0183]

Thinking of a VERY slow fade, I would imagine it to be the most boring display ever. After watching this, I have to admit I was wrong. It is one of the nicest and most relaxing "patterns" that I have seen yet. I just bought a microcontroller kit recently; I'm going to be utilizing this slooow fade soon.

[MacertoVideo]

Is possible share the project?

Have you a Blog/Site private?

[pdslacker]

i feel like you could program the arduino to do so much more than this :\

[T4KK13]

Have you even taken the time to watch just 43 seconds? As said in the description, slow motion ^x^

[RABOBOX]

can you share some off your work

like the wireing and coding (A)

willem

[EineBeBoP]

Would you please share your code and wiring diagram? I'd really love to build myself a table based on this.

Perhaps just the simple color changing code, and not the more complicated stuff?

[Arnadeaa]

I'd like ask you about this same. Would you? :) Please.

[cuteboymimmi]

i bought 50 rgb leds for $6.99

[solomsolomol]

you know that this is the same way the new LED screens work ? really ,try to make show a photo or something

[MultiViews]

A led screen/ tv is only backlit by led's but the OLED is different ;) search that :D

[DrugarTito]

Well......this can be good thing,if you are HIGH!!!WTF?

[carbonunit]

i will stick with the lava lamp

[BobbyOntharun]

and i thought i was high

[misfitdoll23]

Damn that's cool. Where did you get it at?

[angelofmusic246]

I need to make one. How did you do it? Is your code open source?

[TheRomanticRevenge]

That's amazing. I want one in my room.

[undrwatrgypsy]

u use those tables to get girls to stand on the and strip for you..that, or smoke a shitload and trip out with the table...:)

[PatMan0183]

@undrwatrgypsy I, being a nerd, wasn't even thinking of that. Now that you mention it, I think it would be a disgrace to use it for ANYTHING BUT stripping & smoking. Thumbs Up!!

[zatai10]

table: such a piece of furniture specifically used for serving food to those seated at it.

[wesleyvb99]

thats what i need in my bachelor pad ;)

[eSilva90]

purpose?

[MachTo5]

it better be water proof "DUKEY STOP PISSING MY TABLE FREAKING 3RD ONE THIS WEEK MAN!"

[bfboobie]

macguyver built this table with a paperclip, a stick of gum, and a section of rubber tube

[manicreaper]

Simply superb, completely makes the Mona Lisa seem a mere mockery of all things art.

[TodA51]

That's why she's smiling.

Incidentially, it isn't really worth seeing for the who 2s you can, after getting through the crowds of people who want to see the Mona Lisa.

[manicreaper]

Haha to be quite frank i was being somewhat sarcastic about the quality of the quality of art I see in the video, perhaps I'm ignorant but i prefer to praise the skill and dedication it takes to make a painting with an easel. However I do consider the Mona Lisa to be quite, for a lack of a better term "over rated". It just seems far too simple to me, same goes for the graphics displayed. On a side note I'm willing to argue as I am a ludicrously bored 17 year old. Any comments?

[Joe012693]

what?

[wesleyvb99]

eh you're right. i don't understand it either.

[kolob3]

hola

[InsideLosAngeles]

I would like to purchase twenty of these and set them against its side and cover my wall.

[JordynLynnn]

beautiful

[Danzairox]

yo where can i get myself one of these ?

[zooto68]

Nice. Is your schematic open source? If so where can we find it please? What about the code too?

[Booshibonton]

UGH! It's... so... beautiful D: So... IKEA :D

[nanogirl]

So cool!

[rizadrkm]

WOW superb man.

[videosyasi]

this is soo cool dude, you gotta tell me how to build one for me ! :)

[zooto68]

Very nice but you have no details. How is it driven? How many LED's? What are the segmented boxes made out of?
