This project is on the 2017 Hackaday Prize

[@russkydeutsch]

Some advice for you: The music in this video is too loud. People cannot hear what you are saying.

[@21O7ty]

Thats why i turned on CC lol

[@rodrigosanchez3150]

I always tought this project wasn't difficult or expensive to make. Thanks a lot Lab 1314. Once finished I will upload it to share it with you fellows.

[@JeanPerardel]

thanks !

[@titusariel84]

you all prolly dont care at all but does someone know of a method to get back into an instagram account? I stupidly lost the password. I would love any assistance you can give me.

[@emmanuelmarlon6]

@Titus Ariel instablaster ;)

[@titusariel84]

@Emmanuel Marlon Thanks so much for your reply. I found the site on google and Im in the hacking process now. Seems to take quite some time so I will get back to you later with my results.

[@titusariel84]

@Emmanuel Marlon it worked and I actually got access to my account again. I'm so happy! Thank you so much you really help me out !

[@god_damn9661]

Lab 1314 i like ur vids and interacting! just a small big thing: dont let that backround music ruining ur great job!

[@JeanPerardel]

Thanks for the advice. Sorry about that :s

[@qzorn4440]

very nice, you do not know how many times that i have looked for scanner imaging or real line camera info... and using opencv, etc opens up a new world for hobby projects. thanks :)

[@KiloFeenix]

And now they sell these on Amazon!

[@krajeq]

Hi! Could you show us some more things about making a touchscreen like this? i would really like to see it working in like paint

[@radab4989]

Awesome ! I love it ! Thanks for sharing !

[@missingtulips]

Can you make a video step by step for the diy touch screen pretty pretty please?

[@JeanPerardel]

Hi, I made a tutorial on Hackaday. Maybe later for the video :) hackaday.io/project/27155-magic-frame-turn-everything-into-a-touch-area

[@playerx4283]

Question: Do all CIS Sensors natively support IR-Light? Because they are meant for picking up RGB Light which shouldnt be the same wavelength (at least i think so). Do they still pick it up? And if so, how did u manage to block or at least minimalise the 'normal' light to just work with the IR LEDs and not the light from surroundings or the TV? Couldnt really find anything on the WWW so it would be amazing if someone could give me some answers. Oh and BTW, amazing project, love it ;D

[@JeanPerardel]

I would say they are probably not optimise for that wavelength but IR is very close to red so in most light receptor for red can see IR... To block other wavelength, I used a mix of paper filter 106 primary red and 181 congo blue (link at the end of the part 2 here: www.instructables.com/id/Touch-Screen-Coffee-Table-DIY-With-32-TV-and-Low-C/ ) Another solution would be to add a analog filter synchronize o the LED blink... A fun little electronic work :p

[@playerx4283]

@@JeanPerardel thank you very much for the answer :D

[@soscilogical1904]

Very nice video! I have a question... can it work outdoors on a cloudy day, and even on a bright day, if it is in the shadows?

[@dmcteknologiindonesia7780]

Nice application of Touch screen !

[@paparoysworkshop]

Very interesting. You have a new subscriber.

[@CrazyCoupleDIY]

Very well done mate

[@mte874]

🙏👏👏👏 Thank you very much!

[@geovanniherrera1366]

Is there a way to add leds and sensors in the top and bottom of the frame to improve precision ? I mean like adding Y axes to the coordenates

[@JeanPerardel]

You add as much LED or sensor as you want. The thing is, you need to work on faster processing to keep a good reading frequency. An easy approach would be to use Teensy 4.0 or FPGA to have faster analog read.

[@ravilpatel8629]

hey dude..did you use one or two cid sensors for your 32" tv? cid sensor part# or which scanner it came from?

[@JeanPerardel]

Sorry , late answer... I used only 1 CCD with the TV. You have all the details on the Hackaday project : hackaday.io/project/27155-magic-frame-turn-everything-into-a-touch-area

[@aboozhajjar5829]

Very nice I'm sure you'll win the prize Great job

[@JeanPerardel]

Thanks a lot :-)

[@jamesgarlick4573]

Wait... you can use those scanner lights for RGB lighting? I gotta get one!

[@JeanPerardel]

Yes, the light guide is pretty good :)

[@eugenex8892]

Cool idea!

[@geovanniherrera1366]

Thats amazing dude !

[@colhany]

Wow this is pretty impressive!

[@JeanPerardel]

Thanks, I am working on a new project with mouse sensors now, we will see what it can do :)

[@colhany]

@@JeanPerardel lol I'm surprised you still reply even after a year! Anyways, looking forward to it and gonna turn on notifications, I was really impressed as I never heard about anyone hacking a scanner's sensor before!

[@colhany]

Pretty cheapo relatively and very impressove at the same time! Thanks!

[@mantonsasmita261]

wow 😄 u amazing think awesome

[@devinhuff7828]

or make it easy and just get one of Music Computing 4K smart screens

*logan you are my hero*

[@samajier2566]

Kreatif juga

[@itschrisonlinecom]

What happens if you line up object between the ir leds and the ccd?

[@JeanPerardel]

It depends how close the lined objects are from each other. if there is enough space, we should be able to see three maybe four objects. But if they are too close, we are going to see one long object.

[@Unikatze]

If I were to do this to play Tabletop RPGs such as pathfinder. Would it work for the player to set down their miniatures and have the software I use recognize where they are positioned?

[@facinorous]

Let me know if you figure something out. Very interested in beginning this project for this very thing, though I haven't even fully decided in a program yet ;)

[@JeanPerardel]

Hi, sorry for the late answer... To recognise the miniatures it will be more complicated of course. Some use a grid of RFID reader with Tags on the figurine (but quickly expensive and less precise). With this method I would use some IR emitter on the miniatures to make a difference between them. But choosing sensors will always depend on the size of the table/number of figurines/ precision/price.... tell me if you need more help, I should be around on the next few weeks :)

[@seanquenma680]

u got yourself a new subbie

[@JeanPerardel]

Thanks :)

[@seanquenma680]

thanks

[@karthikjonnala5837]

can we use arduino uno in place of raspberry Pi.........

[@JeanPerardel]

We are actually using Arduino to read the sensors and blink the LED. The Raspberry Pi is only for the GUI parts. But in this case I use a Teensy Arduino board instead of a UNO. It's the same but faster and with more IO.

[@TheHrishi25]

whats the background music?

[@JeanPerardel]

It's at the end of the video : Bensound "Cute" & "Ukulele"

[@d.j.1112]

"Never gonna give you up" by Rick Astley

[@allanyabillo9341]

did you programmed it?

[@JeanPerardel]

of course ;)

[@VandepoelM]

Whats the 'fps'?

[@JeanPerardel]

Hi, it depend on the precision and size of the table (so the number of sensors and LED). You can reach 100fps if you use one Teensy board per LED with one sensor. Or even way more with a FPGA :p
