Automated DVD dispenser


[Andrew] made this DVD dispenser for his senior project in high school. It is using an ATmega8515 for the brains, and a custom coded driver for the LCD. As you can see in the video, after the break, you can select a DVD by various identifiers such as genre or title. It then pushes that DVD out of the rack so you can grab it. Right now, all the DVDs have to be placed in predetermined positions, but it’s not a bad start at all. Thanks for sending this in [Andrew].

  1. It’s a nice project,
    tough, a bit slow.
    he could have built a rotary dispenser, a la

    the LCD is well done!
    how are the menu’s updated when he expands his collection?

  2. Yeah it is slow, I used a stepper that my school already had, so in order to get enough torque I had to slow it down.

  3. ba. good luck at MIT…you magnificent bastard :P
    really, nice work you should be very proud, and i’m sure there are greater things to come from you…

  4. pirated movies!

    Pretty neat if you can get the setup in an enclosure to protect it from the elements of your home. The bar that the pickup arm moves on can definitely be optimized for its seek time.

  5. It’s pretty nice as a proof of concept- the title on the LCD is neat as well :)

    Now all it needs is a little SAPI automation so you can say “Computer: retrieve a random DVD from genre action film”

  6. -Nice- project!

    MIT is getting another good one. :)

    -and i love the dimwits suggesting alternate storage when the project was clearly for school.

    this place rocks on so many levels.

  7. hmm quite a cool senior project. mine was a flash video star wars scene, no i am not swk.

    one thought to improve the speed and size, get an old computerized plotter for the guts. I see them all the time at auctions for various businesses and they usually go for a few bucks.

    take the roller feed out and just use the x-axis and the pen up-down to push it. i am sure a quick mod of some open source plotting software would handle the selection easily

  8. how is this automatic if it doesnt just hand you DVDs on its own? i think that would be way more automated. getting a cup of coffee and RUSH HOUR 2!!! gee thanks DVD dispenser, you predicted my every need! oh wait its not automatic its automated. nvm. nice job.

  9. @ compufobia but that only holds 100, with customization it could probably range from 500+…

    *HINT HINT Andrew*

  10. Hideously slow but a very good start, with greater speed this could be seriously usefull for managing lots of CD’s. Good luck.

  11. @Ste@l but you can daisy chain like 127 of them together so could be a crap ton of dvds/cds. 12,700 but the big question is, why not just buy a hard drive.

  12. apparently most people didnt get it. i would love to have something like that for my games, so they dont get scratched, lost. great for making sure no disk got lost. simple sensor to make sure the disk is there, and a bit of more effort, and it could inventory the disks! if i could buy something like that, i would. the only down side, it doesnt put the disk in a drive :( all well. still is cool, especially the lcd display :)
