Kickstarter

We are in the final hours!
This is your last chance, if you have not already donated, to receive a drawing at these prices.
I will never sell another drawing for these prices again so tell all of your friends!

I will continue to sell drawings after the Kickstarter project ends. If you are interested, please send me an email.

Thanks for your support!

I decided to re-build the arm machine now that the funding can cover it. I plan on starting the production of the new machine in the next few weeks.
I don't have much code or plans yet because I am still deciding on the materials I will use.

As for the technical side. I plan to fabricate my own unique PCB that will run the stepper motors. The machine runs on the arduino language so It would be very easy to use other systems for this purpose. For example, my first machine was made using an Arduino Duemilanove in conjunction with an Adafruit Motor Shield. (This may be the cheapest way to get started) If you try my code, you may need to change the stepper motor controls for your specific setup. Other boards used in 3axis cnc systems (like the reprap or makerbot) may also be used but I have not tested them.

I have received a good amount of interest in the code for the wall mount model. I have included a link to the code required for the arduino and Processing.

The wall machine works by converting each incoming coordinate into a Polar system. It does this by running the Pythagorean theorem for each point. This figures out how long each belt needs to be to arrive at that point.

The machine is designed to be flexible. I have included a Processing Sketch that will take Vector SVG files and send one point at a time to the machine. (you will need the Geomerative library to use this sketch http://www.ricardmarxer.com/geomerative/ )

If you take a look at the code, you will see that the machine can work with just about any program that can send serial message in the correct format.

the format for sending coordinates to the machine is as follows, Ten digits, the first 5 being the X values and the second 5 being the Y values. If your sending a small number, add leading zeros so it will always be 10 digits. An asterisk will reset the previous buffered coordinate and expect a new set of coords after it.

sending "+" or "-" to the machine will alternate the servo to lift the pen off of the page.

I have tested it with Max/msp and Processing only, but I imagine that whatever language you prefer should work fine.

Let me know if you have questions. This is by no means a plug+play type system and you will need to develop the mechanism first. My coding skills are meager at best so if you have any suggestions I would be happy to hear them.

Hello everyone.
Again I want to thank all of you who donated for this project. It has been a huge success and I am very excited to start working on the new drawing machine.

As for the Artworks that the Donators will receive. Each is made by the Wall Mount model using my unique algorithm.
Here are some samples to choose from:
(please let me know if you have a specific artwork that you prefer, first come first serve.)

Note: these included drawings are reserved for those who donated $100 or more. If you do not send me a preference for what art you would like, I will choose for you.

Best,
Harvey Moon

I have been working on a bunch of new artworks for those of you who donated.

Here is a small sample of what I have been doing.

Happy Holidays,

I have an update of the Mechanical front.
I have posted a really simple plan design in google sketchup.
I think I will end up doing it in illustrator.

I am thinking of starting a sourceForge site. If someone has some experience with starting one, send me a message.

I also have a brief video demonstration of the prototype arm moving.

Thanks for the support! Leave comments with questions or suggestions.

Happy Hollidays,
Harvey Moon
