I do not really update this blog very often anymore, becuase I am posting and helping out over on Endless Sphere instead. <br /><br />http://endless-sphere.com/forums<br /><br />M.E.https://www.blogger.com/profile/15375034485988839284noreply@blogger.comtag:blogger.com,1999:blog-6231841547435511043.post-21529133342397281102012-08-19T23:16:48.930-07:002012-08-19T23:16:48.930-07:00What did you use for the wiring and controlability...What did you use for the wiring and controlability of the motors?

Doesn't seem like it to me, but I guess I'm used to the whole idea of what I do. :)<BR/><BR/>Well, I borrowed the idea of the skate wheels from Jim Rudholm's friction drive setup (along with the basic version of much of 1.0), except that he used skateboard wheels. The only reason I used skate wheels instead of skateboard wheels is because it was $10 for a skateboard (with 4 wheels) at the thrift store, but only a couple bucks for a pair of skates (with 8 wheels). <BR/><BR/>I didn't examine either one closely enough before buying the skates to notice any significant differences (besides color); they both looked about the same diameter and width at the glance I gave them looking for wear and tear. I figured they'd both be constructed of some sort of hard core with rubber coating of some type, and bearings inside. I wasn't sure if I'd get removable bearings or not, and figured on having to destructively remove those (but didn't have to, fortunately, as I can actually use more bearings like this). <BR/><BR/>I'm sure there are better skate/board wheels I could use for this, but I didn't look around for anything other than what was in the thrift store before using these, as it was really more of a "lets just DO something" kind of day. :-)<BR/><BR/><BR/>2.0 is definitely a huge step forward from 1.0, at least in the idea of it, and how it has performed so far in it's rudimentary incomplete state. Once it's on a PWM controller (as 1.0 was before it smoked from the midday heat while in use), and I complete the tensioner portion that lets me adjust the tension of it on-the-fly, and disengage it from the tire entirely when not needed, it will definitely be better.<BR/><BR/><BR/>I'm not sure what I could do about a starship or a time machine, but hey, you never know until you try. :) I sure wouldn't have imagined motorizing my bike 20 years ago (which kind of surprises me, in that I've been a gadgeteer for as long as I can remember). I *might* have imagined putting lights all over it, though I never did that (I did design a totally electronic dashboard for a 1968 Mustang I was going to rebuild, but never built it, as I gave the car to my mom when hers died quite suddenly, leaving her with no way to get to her many-miles-away daily job (whereas mine was close enough to bike/bus to)). <BR/><BR/><BR/>Now, Jessica in one of her characters' personas might be able to help you more than I, but I definitely get your meaning. :-PM.E.https://www.blogger.com/profile/15375034485988839284noreply@blogger.comtag:blogger.com,1999:blog-6231841547435511043.post-80748327733082678142008-06-13T22:17:00.000-07:002008-06-13T22:17:00.000-07:00That is astonishing.

I know they make lots of variations of those. <BR/><BR/>I loved the detailed photos and descriptions of every step in the process of 2.0. It seems like a huge step forward from the previous model. <BR/><BR/>Your ability to make useful and functional end designs out of a mish-mash of whatever pieces you have been able to gather will never cease to amaze me. I have to say, should my starship ever crash land on an inhospitable world, or my time machine bust down and leave me stranded in the outskirts of Knossos circa 1700 BC, there isn't anyone else I'd prefer to be with to bail me out. <BR/><BR/>Well, except maybe Jessica Alba, but that's assuming another set of circumstances entirely.Unknownhttps://www.blogger.com/profile/12700460546706812466noreply@blogger.com
