Following on my recent posts on the hackable Monkeylectric LED spoke lights and the Altoids tins of bicycle hacks, I’d like to share an idea that I’ve been toying with on and off for the past year. I don’t have the parts, tools, or expertise to build this myself, but perhaps you do, so I’ll share:
The idea is to build an automatic continuous transmission for a bicycle, by wiring up a controller for a NuVinci CVP designed to maintain a constant level of tension on the chain.
Let me start by saying that I believe in visibility. And not in the dim-red-blinky kind of way. A healthy dose of LEDs and reflective tape cover both me and my bicycle when I ride after dark. But while my 4-AA front Cateye is quite bright, and my PlanetBike SuperFlash on back is nearly unmissable, my side visibility falls short. So a few years ago I picked up a pair of Hokey Spokes, and attached one to each wheel. (These battery-powered units attach to a spoke and fill the wheel with light from 16 yellow LEDs when it is spinning.) Last week, I took off the Hokey Spokes to try out something new: the Monkeylectric m132s. I’ll start with a few videos…
I spotted this clever website today (via), which plots the number of Google results for various spellings of one particular expression. Now I, too, have generated statistics on various spellings of particular words, and have just yesterday posted them online. This includes about 100,000 spellings of about 3,000 English words, collected through the SpellBEE activity, as part of my dissertation work…
