The Banksy-BotRyan Hedblom, 12/7/14by

The Banksy-Bot is an automated graffiti tagging robot. Named after the anonymous graffiti artist

“Bansky” from the United Kingdom, the robot uses two bi-directional gear motors to lift a can of spray

paint and actuate its nozzle. To lift the can, one gear motor is fastened to a pulley via a belt. The belt

is attached to the back of a spray paint carriage gliding on PVC rails. To actuate the nozzle, a lead screw

mechanism is utilized, which transfers the torque of the second gear motor down onto the nozzle

through a modified C-Clamp. The robot sprays a pre-cut stencil placed against a faux-brick wall.

All in all, the Banksy Bot is assuredly UK’s most wanted automated vandal.

FUNCTION: Beats Pro is a mid-range studio headphone set produced by Beats Audio. The headphones are constructed of a combination of anodized aluminum and rigid plastics, making them durable and lightweight. The cans utilize single moving coil drivers and sound cancellation technology to deliver pristine audio with augmented bass frequencies.

How it works: 1.) Moving Coil Driver: Inside the can (the part that covers the ear) there is a single copper coil that vibrates to produce sound. The coil receives electrical signals from a cable connecting it to a signal producer – such as an iPod or Mp3 player – and due to Faraday’s Law of magnetism, the oscillation of charge causes the coil to be rapidly displaced. The displacement of the coil pushes the surrounding air, which generates longitudinal sound waves. The sound enters the ear directly and is received by stereocilia in the cochlea. The stereocilia convert the vibrations into electrical signals, which are interpreted by the brain. 2.) Cans: The cans are comprised of four main components: the aluminum casing, plastic body, plastic grating, and the foam cups. The aforementioned coil is placed directly in the plastic body; the plastic grating fits over the coil and clamps to the body, “sealing” the coil into the body; the foam cups fit over the plastic grating to cushion the ear; the body fits into the aluminum casing and is held together by an adhesive. (See drawing) 3.) Bridge: The bridge connects the cans to the headband, which fits over the head. The bridge consists of an aluminum ring that fits around the can, a toothed track, and a steel pin. The aluminum ring is attached to the toothed track via the pin. The pin holds the two components together and allows the ring to rotate 90 degrees about its axis — as a result, the cans (which are attached to the ring) can swing up allowing the headphones to be compacted. 4.) Headband: The headband consists of an upper and lower band covered by synthetic leather (both bands are formed from a lightweight aluminum). The lower band has a toothed plastic track screwed into it on the inner side, which allows for the cups to be raised and lowered to fit various head sizes. The plastic track holds the toothed element from the bridge and allows the element to smoothly slide up and down along the track. The lower headband also carries a wire which transfers signal from can to can. The upper and lower bands converge at the end of the band in a small rectangular aluminum component.

Interesting Features: The most interesting features of this product are the ones that contribute to its durable and compact nature. The steel pins that allow the cans to swivel inward are a crucial feature for those who need to place headphones in a backpack or other compact storage area. Additionally, the steel composition ensures the pivots are not points of weakness and can handle quite a bit of strain. Lastly, the toothed components that allow for adjustable band size are an incredibly intuitive but crucial feature.
