The document describes the Cash Machine installation project at the New Children's Museum in San Diego. It summarizes the key components of the interactive fundraising installation, including the pneumatics using tubing and a cyclone, bill detection using infrared sensors, and incorporating noise, light, and movement using bells, servos, and styrofoam sculptures. The project aimed to create a whimsical experience that detects money and triggers sounds and motions.

A Series of Tubes, Motors, Bells, Clamps, Styrofoam, & Arduinos The Cash Machine Installation at The New Childrens Museum, San Diego Tod E. Kurt and Carlyn Maw teampneumo.com 20 July 2012 Sketching12 PDX Wednesday, July 25, 12 Hello!
Machine Project Provides resources to, and collaborates with, artists working with technology; promotes / Mark Allen interaction between artists, scientists, poets, technicians and performers. Wednesday, July 25, 12 What is Machine Project Mark Allens brainchild idea. Not an art gallery. Not a hackerspace. But has art openings and classes on Arduino and fabric sensors. Projects at LACMA, Walker, Hammer, MOCA, Hayward, etc.

What we wanted A whimsical experience of motion & sound, demonstrating cool physics principles that sucks money out of peoples hands. This was the result. Wednesday, July 25, 12

! ! ! ! Initial Proposal Make stuff up. Dont forget the bells & whistles Wednesday, July 25, 12 Our design brief was brief: - Detect bills - Make noises, 鍖ash lights, make motion - Use 3 HP Dust Collector (Harbor Freight, Red) if possible Stuff Hanging Off Bigger Dust Detector Literal bells & whistles First Idea adjustment (inlet pipe organ/reed instrument vetoed)
Also: Open Design ! Modular, both technically & artistically Manufacturable, with modern fabrication techniques ! !

Anatomy of the Cash Machine Pneumatics Dollar Bill Detection Sound & Light Movement Wednesday, July 25, 12 Pneumatics - Includes the tubing, the cyclone and the impeller Bill Detection - Sensor for the bills and a special mounting harness for them Sound & Light - Wanted real world behaviors so we had to 鍖gure out the best way to approach that. Movement - And there needed to be movement on the wall that had to be very large.
Pneumatics Impeller & Impeller Trigger, Cyclone, 200 ft. of Tube. Wednesday, July 25, 12
Pneumatics Recon, Sketches, Animatics Wednesday, July 25, 12 Animation movie of how it might look in the space. The pneumatics are the tubing, the cyclone, and the impeller that all need to 鍖nd a home in a pretty stunning space. The space is very vertical: our main elements would start at the 15 feet and go up to 35 feet. This was a good experiment on how to convert architectural diagrams into a 3D model for visualization.

45 Pneumatics: How to trigger 220V from a distance? Wednesday, July 25, 12 Possible trigger solutions: - Run wire (Would be ugly, issues with wire length: its 80ft along wall, 40ft line-of-sight) - Considered doing a custom radio solution, but that didnt solve having a UL rated 220V switching solution. - Ended up 鍖nding wireless remote designed for dust collectors Thank you Amazon (Amazon as research tool)
Pneumatics: Hack an existing product to switch 220V. Wednesday, July 25, 12 Using a Long Ranger III wireless remote for 220V woodworking equipment. Remote taken apart and circuit made to push buttons on remote with relays. Circuit soldered down on a SparkFun ProtoShield But that was 鍖akey for some not understood reason So switched to custom Xbee shield circuit. Just toggle digital pin, not full serial, and part of shield stack where most Xbee shields suck.
Bill Detection Show the Arduino the Money Wednesday, July 25, 12
Bill Detection: IR Beam Break Wednesday, July 25, 12 Render from proposal. A kind of clamp that surrounds the tube and has embedded sensors, holding a box of electronics. Challenges we had to 鍖gure out: - Can we really detect bills? - Will this mounting solution work? - How to actually build the mounts? Lets assume IR Beam-Break Would the tube refract the light? - Speed of detections, are the sensors fast enough - Tolerance of Ambient Light How to mount the sensors? - Use existing tube mounting hardware? - Design our own laser cut mounting rings? - Or design our own 3D printed clamps? So what are those components... (pictures of lil ring boards) Standard IR LED and standard TV IR remote control detector That proved useful in testing later on installed tubes (use TV remote to trigger) IR detectors need modulated IR light, Helps 鍖lter out ambient light changes To modulate light, need Arduino hardware timers, cant delay() this
Bill Detection: Lots of tweaking for sensor ring itself Wednesday, July 25, 12 Many design iterations of the sensor rings and the electronics box Had around 40 versions, about 10 fabbed. Will it hold? Will it align the sensors correctly?
Bill Detection: Testing Wednesday, July 25, 12 First prototype PCB (fabbed 3 versions total) 3D printed rings act as both clamps around the pipe and as mounts for sensor boards
Noise & Light Bells, Servo Motors & MaxMs Wednesday, July 25, 12 Tried different bell types (Amazon & Guitar Center as research tool) - Desk bells - Jingle bells - Cow bells - Shaker Sticks - Drums & Cymbals Needed something that cuts through the noise but isnt annoying. Childrens handbells seemed to best solution.
Noise & Light: Bells, Bells, Bells, but no cowbell Wednesday, July 25, 12 Tried different bell types (Amazon & Guitar Center as research tool) - Desk bells - Jingle bells - Cow bells - Shaker Sticks - Drums & Cymbals Needed something that cuts through the noise but isnt annoying. Childrens handbells seemed to best solution.
Noise & Light: Render of 鍖nal bill sensor bell box Wednesday, July 25, 12
bill sensors micro BlinkM servo MaxM springy striker bell Noise & Light: Mass Manufacture Wednesday, July 25, 12 Production bell box. Laser-cut wood form the box, 3d printed sensor rings Everything painted Machine Project Red And the arrangement of bells produce a custom melody
Spinny Bits Styrofoam Fantasy Wednesday, July 25, 12 This was not really part of the original project plan, and mentally had started out as little 鍖ags and pinwheels. But realized that we would need some fairly large objects to 鍖ll the volume of the space. Servo drivable / combination of full rotation and regular for different behaviors. Some motion all the time and some just a trigger reward. LIGHT Texture
Spinny Bits: Design Research Wednesday, July 25, 12 Initial designs Spikey Flat More 3 Dimensional / More Visual Volume / Less Fragile / More Asymmetric Needed to change mounting style (there is a hole down the middle)
Spinny Bits: Material & Process Research Wednesday, July 25, 12 Styrofoam, what to cover the styrofoam with, what could expedite the process
Spinny Bits: Manufacturing Process Wednesday, July 25, 12 Manufacturing Process Lots of tests with different tools Picture of Me White Assembled On the Grass Painted Red Primed?

Spinny Bits: Layout and Feel Wednesday, July 25, 12 What kind of motor are they attached to, size factor, what order, how much Styrofoam of what sizes, how much balsa wood of each size? Nice to have a sketch book, but also need a spreadsheet.
Spinny Bits: Upgraded mechatronics: 3d prints replaced w/ ServoCity gearbox rated to 200 lbs Wednesday, July 25, 12
The Pay Off Wednesday, July 25, 12 Movie of it in use
The Pay Off Wednesday, July 25, 12
Results More money donated to museum in one month vs previous two years Kids and adults love it Wednesday, July 25, 12 What we learned from children watching it... Fixing the 鍖ash problem... Good for us that it is a childrens museum More challenging because has to be more hardened Excellent because the HAVE a maintenance staff with skills.
In the future... Networked bill detectors Evolving behaviors for spinnybits DFM iteration to make kit-able Pitch kit to other museums Wednesday, July 25, 12 What we learned from children watching it... Fixing the 鍖ash problem... Good for us that it is a childrens museum More challenging because has to be more hardened Excellent because the HAVE a maintenance staff with skills. Re鍖ne the behaviors of the spinners Replaced on of the spinners where the arm didnt survive (the glue didnt take)
