I’m going into this slightly unprepared so need some words of advice from the pros as to what to buy before I start tinkering… I have attached a pdf with a rough outline of my product idea (however it’s more of a general design than a construction document).
In a nutshell; the chairs need to heat up the closer they are to the ‘alpha chair’ and every so often a new alpha chair is selected and the process begins again.
On a small prototype scale the only way I can contemplate doing this is to use those usb mug warmers to heat the inside of the chairs. Can you directly power this type of usb using arduino or would you need to start tinkering with the circuitry in the heater?
I have been told that infra-red proximity detectors are a no-no so I am using a copper squares, 5x5 (check out pdf), to connect each chair to the mainframe. In essence, in this prototype; the squares act as the alpha and the orbiting beta chairs, not the chairs themselves, the chair objects are simply complete a circuit, tell the arduino they are active and facilitate the heat. In the pdf these squares are made from 2 triangles; a plus and a minus which connects to the relative conducting parts on the bottom of the chair.
SO! I hope you understand my concept. I’d welcome any criticisms or feedback and most certainly your analysis on what you think I might need to buy!
Thanks very much,
