Possible to build one (with less "pixels") to start with?

No kinect, just an arduino and lots and lots of servos. smiley

How would you do it? smiley

Describes why (composite) video is more complicated than audio.

Simpler circuit which uses an IC

Replace 10k pot with a digital one like this.

That's a concept picture and not available as far as I know.

Maybe if enough people want this (and why not?) Adafruit could easily produce something like this.

Starting point for this project I would guess, is a raspberry pi with suitable video player software that can be controlled by a (python?) script.

Depending on what type of control inputs you have, you could use the GPIO pins on the Pi or a separate arduino board.

Asking this question on the Pi forum is the best way to do this.

If you just want an easy way to transfer your breadboard design to something more permanent, then this is for you.

You will need a basic arduino circuit like this
to start with, then add the other components from your breadboard.

If you want a "proper" PCB for your project, then you'd need to learn eaglecad or kicad design software.

Another alternative is where you can have a PCB produced from the breadboard design software.

Maybe this?

Nice, but could you use cotton wool instead of that other type of stuffing which I've never heard of?

Starting to learn KiCad.
The clearest (step by step tutorial) I`ve found is here

If you are thinking of selling your circuit boards in the future and don`t want to spend money on software, use Kicad.
Warning long video! Part1 45m, part 2 over an hour!

I also watched this

and was quite impressed.

Diptrace also has a free version (not for profit) version, no size limit but 300 pin limit.

Portable Amiga Mod Player! smiley-grin

I still have a collection of my fav amiga mods stored away in the depths of this hard drive somewhere. smiley

Yes, that's the total width of the display, each number is about 20mm high.

Like this? (6" Display)
The photo does not do it justice, it's a nice large display.

I guess its possible using custom characters on a "normal" 4 line display?

Thanks for the replies.

I'm looking at this circuit (my application has nothing to do with doors though) smiley
The op amp in this case is used as comparator, I could probably do away with this and feed the output of the transistor to the arduino and do the same in software?

LM324, LM358, other?

It will be for a photodiode amp circuit.

Is not the MakerBot platform arduino based?, I think they made quite a bit of money out of that.
