waterproof boxes

Pelican cases are the ultimate underwater enclosure, but what about Otterboxes?

microfiche reader

microfiche reader that then plays music depending on light levels.  Uses a light sensor and a BS2 to output midi.  Shown at this years Maker Faire.

great arduino based MIDI work including Toriton water surface instrument by Sebastian Tomczak

processing and mapping coordinates

To map coordinates on any images, I wrote a processing sketch to display x and y coordinates as a rollover.  Can use this to determine sizes and areas of coral species.

processing

before I forget about an incredible exhibit at MOMA, called Design and the Elastic Mind.  Lots of uses of processing language and some great processing of geographic data

Intersting glockenspiel driven by an Arduino.  USes solenoids and are powered by arduino

underwater sampling system

Starting the design for a medium volume (3L) underwater sampling system.  A place for 12 vdc solenoid valves , or maybe the KIP versions now just need to find flow controllers and totalizers.

Sculpting Recipe

Here is a recipe that will give you a durable, carvable and long lasting hypertufa sculpture. Your aim is to apply this first recipe in thin layers over your armature, building it up to the desired thickness. Then, you will use the 2nd recipe to add one or more layers thick enough to allow you to sculpt to your desired depth.

Recipe for application over the armature
and to build up thickness desired:

1 part Portland cement
1½ parts peat moss
1½ parts coarse sand
Handful of poly fibers
Handful of silica fume

Recipe for the Final Layer(s)

1 part Portland cement
1 part peat moss
1 part coarse sand
Elmer's Carpenter's Exterior Wood Glue
(or other bonding agent)

papier mache artists

Thinking about some papier mache ideas for the next sculpture.  Eith using it or tufa (mixture of peat moss and cement)

Some great work at http://www.papiermache.co.uk/gallery/

Moulds

Balloons
Cheap and indispensable. No release agent needed. The balloon will tear itself away from your dried papier mache easily when burst.

Bowls and plates
These will need to have a release agent applied first to stop the papier mache sticking to them.

 Release agents

 These all must be applied very thinly. They may leave a small residue, which you may not like.

- Vaseline
- Cooking oil
- Washing up liquid

When completely dry, paint with two coats of emulsion paint to seal it and kill the newsprint. You could also use gesso for a slightly tougher base.

bs2 program for ping)))

Using the PING))) ultrasonic sensor I can change LEDs flashing colors with changing distance of a person.

distance ranging and detection

Current project needs a method of detecting the presence of someone in a room who is approaching an interactive sculpture.

First I need to detect that someone is in the room (which activates a response from the sculpture).

Then I need to measure the distance of the observer from the sculpture, as the closer someone gets the different responses will be realized.
This distance detection could be either from an ultrasonic sensor
(from Parallax), or the low cost infra-red detectors from Sharp which are available at http://www.acroname.com/robotics/parts/R48-IR12.html

multiple servo control from PC

Mini SSC from http://www.seetron.com/ssc.htm are useful when using multiple servos (up to 8), controlled from a BASIC Stamp or a PC.  Thanks to the Physical Computing book which is fabulous

new book arrived

Physical Computing by Dan O'Sullivan and Tom Igoe arrived.  Tom Igoe has some amazing work on the web and his students at NYU  have pushed physical computing to some amazing heights.  Should give me a lot to think about with microcontrollers and linking them to computers
