Thanks for the share Chris, looks good. I was most curious about the very low sampling area that must be being used to decide the wave amplitude on this one. I guess that’s limited by the pen width.

I did something similar with my Eggbot; you can get strips of variable width to represent variations in brightness. I put more details at http://www.fastness.co.uk/111120_eggbotBitmap.html I included source code for processing that might be adaptable but the algorithm isn’t really complex

I don’t see any mechanism for doing that – the servo is for a lift. But it’s a very intriguing and elegant idea. Have you seen anything that uses that technique Matt? Could rig a servo to turn the pen.

I reckon it’s a chisel tip pen that is rotated for variable line width.

Those boards look really cool. I may wait too see what you’ve got up your sleeve for the new board. Thanks

I'm planning on using these boards for the physical interface.

On the other hand, you don’t have to machine brass for an interesting gondola. You can use polycaprolactone plastic (Shapelock, Instamorph, Polymorph, Friendly Plastice, etc) to make something that wouldn’t look out of place in “eXistenZ”.

Hey Matt, the microSD breakout is pricey but very neat and dead easy to rig. I don’t think I’d recommend the buttons – it is a bit of a kludge and the code isn’t going to support that kind of interface in the future.

If you’re keen though, I can write it up, though the circuit is embarrassingly crude.

Hi Sandy,
I’m thinking of getting adafruits microSD breakout to make my own standalone machine. Should i add some buttons like your new remote? and if so can you tell me the schematic for the buttons to the mega. Thanks
Matt
