    • ! ! ! ! Initial Ideas & Proposal Monday, October 24, 2011 Our design brief was brief: - Detect bills - Make noises, flash 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)

    • Anatomy of the new system • Pneumatics • Bill Detection • Sound & Light • Movement Monday, October 24, 2011 Can the original be made prettier? 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 figure 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. Monday, October 24, 2011
    • Recon & Initial PlanPneumatics Monday, October 24, 2011 Animation movie of how it might look in the space. The pneumatics again, is the tubing, the impeller and the cyclone that all need to find 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.

    • Pneumatics / Where to place the cyclone and the impeller? Monday, October 24, 2011 The chosen impeller to hopefully work with so much tubeis 3 horse power and 99dB, so it’s not quiet. It also takes 220V. We had some suggestion of different places to go, but in the end they came and got it to do sound checks. Smart move. The put it in the closet. It meant drilling hole for the tube and adding 220V for them. But once we figured out where they were going we still had two major questions to answer: - Will it pull the bills through 150+ feet of tube - How will we trigger it from across the giant lobby?
    • Pneumatics / Will is suck? Monday, October 24, 2011
    • Pneumatics / Will is suck? Monday, October 24, 2011 Bendiness and Length Sharp bends create vortices that reduce suction, but we want a space-filling design Test - Problem: Horizontal The real space is vertical; will our horizontal tests be valid, does gravity play a big role?
    • Pneumatics / How to trigger 220V from a distance? Monday, October 24, 2011 Possible trigger solutions: - Run wire (Would be ugly, issues with wire length: it’s 80ft along wall, 40ft line-of-sight) - Considered doing a custom radio solution, but that didn’t solve having a UL rated 220V switching solution. - Ended up finding wireless remote designed for dust collectors Thank you Amazon (Amazon as research tool)
    • Pneumatics / Hack an existing product. Monday, October 24, 2011 1 of 2 from Hack 220 V 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
    • Pneumatics / Hack an existing product. Monday, October 24, 2011 2 of 2 from Hack 220 V First version of circuit had some intermittent behavior. Second version had some improvements - 9V regulator to emulate 9V battery - added antenna wire to existing antenna to extend range - flying leads replaced with plug-n-socket connection
    • Pneumatics / Submitting the Layout Monday, October 24, 2011 They needed to know ahead of time for mounting hardware ordering We needed to know to design the spinners, supplies ordering (With and without dots) --- Notes about the Cyclone probably not for this talk. -- Cyclone bottom with Lock -- basket ball hoop with red tape & foam for mount -- finding 6 inch to 4 inch adapter for side and 4 inch to 8 inch adapter for top.

    • Show the Arduino the Money. Bill Detection Monday, October 24, 2011
    • ! Bill Detection / The Starting Point Monday, October 24, 2011 Render from proposal. A kind of “clamp” that surrounds the tube and has embedded sensors, holding a box of electronics. Challenges we had to figure out: - Can we really detect bills? - Will this mounting solution work? - How to actually build the mounts? Let’s 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?
    • Bill Detection / IR Beam Break Monday, October 24, 2011 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 filter out ambient light changes To modulate light, need Arduino hardware timers, can’t “delay()” this
    • Bill Detection / Lots of tweaking for sensor ring itself Monday, October 24, 2011 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 / Lots of tweaking for sensor ring itself Monday, October 24, 2011
    • Bill Detection / Custom Shield Monday, October 24, 2011 Picture of Bill Detector Arduino Shield So much in a little space so best course of action was to make custom shield Breadboard version proved out the idea, but can’t use in production.
    • Bill Detection / Custom Shield Monday, October 24, 2011 Picture of production shields
    • Bill Detection / Test Monday, October 24, 2011 First prototype PCB (fabbed 3 versions total) 3D printed rings act as both clamps around the pipe and as mounts for sensor boards
    • Bill Detection / All together Monday, October 24, 2011 Final production version of sensor rings. 3D printed rings act as both clamps around the pipe and as mounts for sensor boards
    • Noise & Light Bells, Servo Motors & MaxMs Monday, October 24, 2011
    • Noise & Light / Bells, Bells, Bells Monday, October 24, 2011 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 isn’t annoying. Children’s handbells seemed to best solution.
    • Noise & Light / Solenoids Vs. Servo Motors Monday, October 24, 2011 Actuation methods – servo motors Bell striking typically done with solenoids b/c they have speed But servos have SWIIING, works in multiple orientations, don’t use as much power
    • Noise & Light / The right striker Monday, October 24, 2011 Picture of servo mounted strikers Servos can’t move fast enough. So we stole springiness from the strikers, they make the up the needed speed And the strikers needed to be hard & dense to get the right tone.
    • Noise & Light / An extra signal Monday, October 24, 2011 Picture of MaxM Super bright, will allow an update of color pattern (light engine) in the future if desired and / or upgrade to strip lights.
    • Noise & Light / The Build Out Monday, October 24, 2011 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 Monday, October 24, 2011
    • Spinny Bits / Baffling Red Whoosie Whatzits Monday, October 24, 2011 This was not really part of the original project plan, and mentally had started out as little flags and pinwheels. But realized that we would need some fairly large objects to fill 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 / Material & Process Research Monday, October 24, 2011 Styrofoam, what to cover the styrofoam with, what could expedite the process
    • Spinny Bits / Design Research Monday, October 24, 2011 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 / The drawing board Monday, October 24, 2011 Me looking tired Designing the “feel” of the entire piece, and the behaviors of each spinny bit.
    • Spinny Bits / Swappable mounting hardware Monday, October 24, 2011 Many iterations of the mechanical linkage to transmit power from servo to spinnybit. Also many iterations of the box itself to hold the servo motor.
    • Spinny Bits / Swappable mounting hardware Monday, October 24, 2011 Close up views of the servo linkage and the spinnybit mounting plate, both 3d printed
    • Spinny Bits / The drawings Monday, October 24, 2011 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 / Manufacturing Process Monday, October 24, 2011 Manufacturing Process Lots of tests with different tools Picture of Me White Assembled On the Grass Painted Red Primed?

    • 4 Days, 5 People The Install Monday, October 24, 2011 Mount Impeller (hole in wall) Mount Cyclone (Attach to rest, add end cap) Bell Boxes Splice Power in from 3 places, wire it to all the boxes Spinny Bit Boxes The Intake Had to Be mounted, lit, child proofed a little.
    • Install / Mounting the tubes Monday, October 24, 2011 Trouble with angles... Mount Pipe Flexible Hose as Gasket There was an app for that. (Clinometer iPhone app helped get the 45 degree angles)
    • Install / Mounting the tubes Monday, October 24, 2011 Flexible Hose as Gasket Cut small lengths of the hose to cushion delicate acrylic tube in metal bracket.
    • Install / Mounting the tubes Monday, October 24, 2011 Tubes installed, now time for bell boxes
    • Install / Mounting bell boxes Monday, October 24, 2011 Giving the bell boxes their approx. location so we could test them.
    • Install / Mounting spinny bits Monday, October 24, 2011 Key holes were drilled into back of motor boxes for mounting
    • Install / Scissor Lift Joy. Monday, October 24, 2011 Being 3 stories up in a scissor lift is fun, but tiring.
    • Install / Occupy San Diego Monday, October 24, 2011 Going on at the same time as our install.
    • October 15th OpeningThe Pay Off Monday, October 24, 2011
    • The Pay Off / Mo’ Money Monday, October 24, 2011
    • The Pay Off / People Playing Monday, October 24, 2011 Movie of it in use
    • But more to go... Monday, October 24, 2011 What we learned from children watching it... Fixing the flash problem... Good for us that it is a children’s museum More challenging because has to be more “hardened” Excellent because the HAVE a maintenance staff with skills. The circuit we showed is actually going in on Wednesday b/c of loose connection Refine the behaviors of the spinners Replaced on of the spinners where the arm didn’t survive (the glue didn’t take)
    • More To Go / Flash Dance Monday, October 24, 2011 Camera flashes trigger all bell boxes
    • Questions? Monday, October 24, 2011
