- Completion of a project. Two 24" x 26" boards (pegboard) filled with 818 blue LEDs, 160 IR emitters, and 190 IR receivers. All organized into 190 "nodes" and powered by two Arduino micro-controllers. I built the coffee table and sized the inner cabinet to accommodate these pegboard reactive surfaces.
The two pieces of pegboard (as well as a good view of the wire "nest" beneath them) can be seen being tested here: • Arduino IR Reactive LE...
The original prototype board can be seen here: • Arduino IR Reactive LE...
This link also contains a vast amount of information such as motivation, similar projects by others, and more on components used.
Camera is a bit old, and low quality. Also, the IR doesn't show up on the camera (IR is invisible to the naked eye, but digital cameras tend to pick it up). Another video was taken with a newer camera, but the IR is more visible on this one: • Reactive LED Coffee Ta...

This table arrived well packaged and on time. th-cam.com/users/postUgkxn94T8Mu1iMnsLCMNOI9srXSsLkI4JXKW Like another reviewer advised, I pulled everything out and made sure everything was included (everything was!). I built it alone and it took me about an hour. The color is great and for the price the lift part works well. As others have mentioned, it’s not the smoothest opening/closing, but it works. The screws do show, but I plan to order white sticker covers if that bothers us too much. Really happy with this table! UPDATE: it’s been over a year since we got this coffee table and we still love it! It gets HEAVY use as our dining table, foot rest, and school desk. Over time, the opening and closing mechanism has gotten smoother. I added a new photo with the white screw cover stickers. They blend in perfectly and make it look a little cleaner. 100% recommend!!!
Awesome! The whole family thought it was spectacular - nice work!
Just stumbled across this by accident and I must say to you, I'm very much impressed by your patience & skill. You see I'm from another planet, it's called "The 60s erector sets & Radio Shack transistors"... lol
There's not much in this world that has impressed me over the yrs, but you certainly have. Good luck to you.
in the future I want my entire floor to be like this.
Jash440 or like leds that create heat so that when you walk on a cold floor it heats under your feet so you dont feel the cold
anthony halstead i duno it would get really cold unless you sleep walk
Anthony, LED's are designed to not create much heat at all... Having them like that would just make them inefficient and pointless >.
Me Gusta i duno maybe make a h.e.d only prob is they would wearout pretty quick
Almost like forest in Pandora from Avatar
Dang.. I watched the build video, and it looked like a beast building this.. but mannnnnn is that cool. I have never seen anything like that before. 50 hours is a long time, but now that I have seen the finished product.. totally worth it. Now you just need to paint that coffee table to match its updated technology. Sooooo cool.
Watching you slide those coasters made me think a long shuffleboard game would be cool if it was built long enough.
I'm impressed that you did this with only 2 Arduinos. I thought you would need more for this.
The TLC5940 made the outputs (essentially) infinitely chainable, and the MUX's allowed me to expand the inputs from 6 to (16 x 6 = ) 96. Otherwise... you're absolutely right. This project wouldve been much too large for a single Arduino.
wow this is badass! I can't help but think how cool it would look behind some flowing water or behind or under a fishtank
chiunque tu sia, meriti una medaglia! Eroe!
Imagine one night you chillin watching tv and the leds go off by itself.
Helal olsun..
Sendeki bu azim ayakta alkışlanır..
Teşekkürler..
Interesting proyect man, greetings from Mexico.
Awesome work.. Men like you need to be awarded for your patience.. Good work brother. Inform me you doing it for retail.
Nice project, looks great.
Very nice work!!!
Nicely done. Good work
This is beautiful.
Got any games for it?
Great job! Really fantastic!
Dude that is epic.
Amazing! (and such patience to see it through lol )
I'm thinking frosted glass... groooovy
Hey man i really love this table it is so cool and satysfying i really appreciate your work
im going to try and build one, some day,probaply
I see a wicked cool air hockey table.
YES THE CAT!!!! in the first video i was like "i wish he would put a cat on it" and ill be damed you did. 10/10
The effect would look much smoother if the glass were frosted. Im not sure if the IR sensors would be able to register through that though.
I was just thinking the same thing, either that or black tinted glass would work aesthetically too. The IR sensors might be dampened a little but should still work.
Great project! Good job! :D
amazing job man
super cool project thanks for sharing
id love to see one with a way higher led "resolution" and maybe distance sensitive to activate different color leds.
closer you get the higher or lower up the color spectrum. would take a LONG time to make but would be sweet.
Cat- "Wh-what, oh, eff this, peace."
Sculpture Junkie I think he just cat-proofed the coffee table - lol!
jfan4reva I could use that for my coffee table. My cat jumps on and steals from drinks when I'm not looking.
Bruh, you can cuss. fuck.
BuilderBoy2701 You're right I _can_. I just save the word up for when I drop a 20 ounce hammer on my little toe.
Really cool, and kudos for all the time you spent on designing and building this!
I am curious though - why didn't you multiplex the table in an x/y array? It'd result in far less wires (1 per row of leds, 1 per column of LEDs, plus a 2nd set for the IR receivers).
i normally don't login to like stuff, but thats beast, nice job
This would be awesome on an air hockey table... assuming it's could react quickly enough.
Time for a revised version with addressable RGB LEDs, like WS2812B or something. Perhaps more and different sensors, and settings to sense/react in different ways, and to run default "screen saver" (table saver?) patterns when not in use. This would look cool as a poker/blackjack table, too.
Marvelous!
This is excellent!
Ok I spoke to soon on your making of the table video, where I said I'd like to have seen more of the finished product... Lol..
NICE JOB
nice work
Great inspiration NYC MR.G
Really cool. I think it would look a lot better with frosted glass.
think again, how does it knows when something is put on the table?
Yes, here's a similar project with frosted glass. th-cam.com/video/L3l-zJafOnc/w-d-xo.htmlm8s
I would love to buy one of these
Ronald Browen now i would love to build one
this is awesome!
This is awesome.
Thats awesome , imagine your whole floor done like that walking down the hallway at night to go the bathroom lol .. Anyways thanks for sharing
now what would be sweet is if you could play that old style game with the slide bats n ball
Very cool !
nice. must be rewarding when that wire mess was done... :)
Frosted glass would look awesome on this.
Ooo... now can you make an air hockey table like this? Or maybe a shuffle board?
my god man, this is amazing! does it draw a lot of power when not used though?
Excellent, magical..
The cat sold me!
Some U of T Engineering students from Spark Design Club were inspired by this design - So we decided to build our own! Not quite as nice as this, but for a student effort over the course of 1 month on weekends and evenings, it turned out pretty well: imgur.com/gallery/AycbJ
Holy crap! I can-NOT believe that this post was shoved in my "might be spam" folder for the past 6 months! This is AMAZING! Incredible work! I see you also planned out a much better wire management scheme =)
This is why I post these videos: To hopefully inspire, and then to subsequently see someone do it better.
Keep it up! You guys rock!
Thanks! :D
Well mainly because the guy who made the imgur post doesn't actually monitor that account. I think he just made it to show his friends - he never replied to any of the comments. Rest assured though that this video is the first thing in the blog/portfolio post I made last year about it to show the inspiration. To be clear though, most of the actual learning how to do it occurred in engineering school.
Very cool !!!
Great Work.
If you shut down all the lights in the room, does it lit up?
They need to make air hockey tables like this
so worth it
excelente, buen trabajo
Can you imagine an air hockey table done up like that
Can you imagine sitting alone in your living room with this thing when all of a sudden the lights start moving slowly toward you...
Makes this into an Air Hockey Table. That'd be cool.
It'd be cool if you could create one with the pixel density of a display.
Amazing Nice work.
What was the final cost for all the parts?
imagine playing dry-ice table hockey on this table!
incredible!!!!
just an aesthetic question would you still be able to defuse the light in any manner? that wouldn't interupt the IR sensors ?
Mighty cool stuff! Next thing you might consider is have the IR sensors report temperature, install RGB LEDs instead of blue and have them light up and colored according to temp. :)
+neousagi This kind of IR sensor does not detect temperature. You could theoretically make it sense the temperature of the room, then light up different colors based on this, but at the end of the day, the electronics involved become an order of magnitude more complex and given that you're inside, this would be rather silly, since the temperature of the room stays the same.
+Ryan Cook Ah... too bad. This sort of think could have had safety applications, where the surface was colored according to the temp of what was on top of it. It would be useful in the kitchen and workshops where high temp items were used.
neousagi one thing they do have is, for instance, on my stove, there is a little warning light which comes on when the electric stovetop is hot, if that's what you mean. By the way, I may have slightly misspoken before, it has occurred to me there may be a way to do what you meant. It would involve measuring the temp of the tabletop, not by infrared, but by temperature sensors like the lm35 or perhaps a little thermistor. Mind you, this is still likely to be a more complex, and significantly more expensive endeavor.
You could could some distortive glass to make it look even cooler, or would this interfere with the IR leds?
2:00 - you should make a game for this table - who can slide their mat the closest to the end without going past.
great job! made the glass frosted for better effects.
it wouldnt work then since the IR receiver is picking up a signal of reflected light from the IR emitter off of the objects up above. if the glass was frosted it would be on all the time.
I know it is a little late, but if you frosted the glass and added a diffuser below the glass layer it would look even better.
it is really good. have you ever think about selling it? and also you may try something semi-transparent glass as a alternative to the normal glass that's way you will have a smooth lightning:)
I might suggest tinting the glass slightly to hide the array but that might not allow the IR through
+Neil Caulfield I used misted acrylic on a project that I did with the IR sensor behind the misted acrylic and the IR still works fine so that should be possible
Will the IR sensors detect clear items such as glass? Or in the case of a drink glass, could an uneven bottom be enough to set off the sensors? I noticed you had coasters under your glasses in this video.
It might look a bit more polishehed if you were to add a layer of wax paper between the LEDs and the glass, or brush the underside of the glass itself (This would help diffuse the LEDs and look a bit less ..."exposed"). I'm considering doing a project like this of my own, though using another technique.
Cool. It's like the force. :D
awesome!
Perhaps this could be incorporated into an air hockey table? Results could go either way though due to speed of puck
You should tint the window unless it affects detection distance.
Love this
Im just trying to make 5 blue LEDs follow a hand playing up and down an accordion keyboard ?
Any circuit ideas ? Welcome
What was the cost of the equipment to make reactive lights? I am looking into this for a university project. Looks great!
excellent
I want to do this to my cars full exterior as a project 2014 Mini Cooper. I need a flexible and thin board/rubber design to make the bends an curves. Also need to figure out a coating on top to make is smooth to touch like a normal paint job. What if I use flat legs with epoxy clear coating?
A lot to figure out right now.
OP, excellent project! just truly a great idea!
I see the U of T Engineering students seem to have a faster response maybe using faster chips? Not sure.
amazing.
Would look really cool with frosted glass
i’d trip out if it started doing it by itself lol
amazing
wow that so cool!!! 😉👍
Now you need to make a Chroma version (like the razer keyboards). RGB ftw :P
I'm late to this party, but if you put a uv reactive 'glow in the dark' paint mix over those bluey LEDs somehow, let's say mix some into resin and pour it over the glass why not, would you get a cool after-glow effect after you make the lights light?
you are genius
very nice. now add some circuit that, it makes some sound as well. for instance from left to right or top to bottom, makes do, re... si different notes. it is perfect 99% now. it become 100%
"😐 don't let the acid droppers anywhere near this table, ok?"
"😩 That's a crazy table, man. I gotta tell those kids with the acid..."
"😬"
"😩 they're gonna flip out man."
"😲"
I want one!
I'd tint the glass in black. Infrared light should have no troubles going through. Though it's a bit odd that it detects plastic plate or journal, since it doesn't emit any heat.
A black tinted glass pane would rule. It would make the light source more mysterious. Actually, the reason it cold-objects is because it doesnt so much pick up on heat, but relies on reflected IR signals. The white dot grid is actually infrared LEDs. The detectors in each blue-LED node are just detecting the emitted light that reflects. They both are sensitive to the same wavelength (roughly).
Funny thing, the table doesnt reflect off my wallet, which is a matte black. Black is a good absorber and the rough surface of the wallet minimize reflections.
oh I see, that's a very smart design
yohash84 i thought glass absorbs infrared radiation. I remember mythbusters proving it.
hmm interesting
It is reflection that causes it not temperature.
Fu#$ing awesome you got a subscriber in me very cool set up and video to show how long it took and the steps it took very cool thank you for sharing. i kept seeing amazing led ideas thwn i saw your touch screen and was blown away. I was looking for a new hobby i think i found one. But you do one and actually talk step by step how to actually do it or make a dvd i would buy it. Or is there any dvds out there already that i could buy. Also did you buy that table or make it because i would like to do this and but make my own tble or furniture which i can do myself or if you have video on furniture you hve done i would love to see it again thank you you made my day
very awesome :)
wow i love this ! one question tho, is it possible for this to increase the resolution to like a normal screen pixel ? i mean could screen be able to do this ?
+yuukiflow I guess if you bought a touch screen, it is rather easy. But to make something like this in a high resolution with IR sensors, it is almost impossible to put it together by hand.
is there a way to make a design on it and make it stay there or can you draw with it and keep it there. That would be a cool idea also and then somehow be able to sve the design and use again later somehow be able to put a memory card in it and be able to save desgns
