A few years ago I saw a video on Youtube for a car wheel light that displayed a message as the wheel rotated.\u00a0 I have seen this same method used on LED lights for bicycle wheels.\u00a0 It was a row of LEDs that were synchronized to the rotation, and as the wheel rotated a few degrees, the LEDs would display the column of a many columned display.\u00a0 As the wheel advanced, the persistence of vision created the message around the perimeter of the wheel. Later I went to Radio Shack and they were selling a\u00a0 small, hand held, battery powered fan with a row of LEDs on one of the blades.\u00a0 When you pressed the button, it displayed a message.\u00a0 The salesdroid demoed it for me: it said <expletive> Radio Shack!<\/p>\n
The software somehow senses when the blade passes a certain point so it can begin to display the message.\u00a0 The rest is just turning the LEDs off and on in the right order and time.<\/p>\n
Aki said he was aware of this and thought about including it in his projects.\u00a0 I was discussing the wheel lights and fan above with the idea that it might be possible to use it in the Wave JT.\u00a0 I thought about how one would mount a small device onto a rotating wheel, but it seems a little bit too complicated for the Wave JT since there are no mounting holes.\u00a0 I later thought about it and I figure that it might be a lot easier to use an arm wave.\u00a0 Like when the button is released there is a burst of LED activity that’s the columns for a few characters being displayed.\u00a0 If the Wave JT is waved – no pun intended – the few characters would appear in the air.\u00a0 This is just enough to display some initial information that would indicate the state of the Wave JT.\u00a0 It’s not a lot but enough to help communicate what’s going on.\u00a0 Two digits can give us the item in a list of a hundred different states of the device.\u00a0 There are other ways to do this.\u00a0 The eight LED could be flashed in two ‘digits’, from 1 1 to 8 8.\u00a0 Zero doesn’t show, and the higher numbers are more difficult to count correctly and may require longer to display.<\/p>\n
