Problems and issues Nov 18 2005

I'm only getting 25 - 35 feet of USB distance when running both the activeWire board and the camera at the same time off the same powered hub. I'm taking power to the hub from a regulated 5V 7805 chip that is connected tothe main 12V light. Inherityly there sounds like I don't have the power supply buffered and separated enough. I don't have capacitors or anything to help clean up the signal though.

The distance is not enough and is not acceptable. My goal was for 60' and now I know that the only way to get 60' or more is to go network with the labjack.com device. I get more pins, more analog, and much more distance.

That means I need to redesign the sub if I'm going to have the capacity to go 500'.

I want network to labjack or computer to computer and USB.

Problem using computer to labjack is need network camera. Solution, switch to security camera via traditional transport to VGA card on computer.

Problem using computer to computer to usb is that it requires two computers and a client server application.

Prefer computer to network labjack.

OR.....

Computer to USB only. Use separate security camera line.

How far can using activeWire only go? Remove USB camera altoghter.

ActiveWire board only distance was discovered to be:

Marble Organizer Art Installation

Multi colored marble collection is dumped into pan a size such that the all the marbles when evenly stacked they take up the size of the pan.

Think large scale LightBrights. The marbles are dumped and shown to the viewer then a machine arm one by one or multiple create an image by picking up a marble out the mess of marbles and placing it into the right space on the final image.

Design each joint in the arm mechanism as relient entity unto itself of accomplishing a goal (which happens to be the goal of the arm)

3D this can be done with the following algorithm

  1. Create n-number of objects
  2. Show the user the objects each individually organized object
  3. Apply gravity to objects to make them drop into a jumbled mess
  4. Have objects collect into a general pool
  5. Pick an object at random
  6. Analyze random object to determine where it best fits in the picture.
    1. Best fit by color is simpliest
    2. Best fit by type
    3. Best fit by size
  7. Choose another random object until no more objects exist
