View Full Version : …from Fossils to Flux is LIVE!

01 May 2011, 1431
Guys, I'm so frikkin excited to finally be able to announce this. Thanks to everyone on ElMoto, and Noah in particular for the push and support, I just loaded the book on Lulu. The cost of it is higher than I wanted, but I don't have much control over that. I did make a download available for cheap, so save a tree and some bucks and go with that.

Hopefully this can be a resource that we can point people to for covering the basics, to get people started in the right direction. The cool thing about Lulu is that I can update it easily and quickly too, if I got something wrong, or to handle new developments.

Thanks again to all you guys, and beer's on me! Well. That's where it usually ends up anyway... :)

Here's the official post:

I’ve been hard at work finishing up the last of the book, and after an epic slam, I’m pleased to report it’s DONE, and LIVE on Lulu.com!


…from Fossils to Flux puts together all the pieces that you need to start your own electric motorcycle conversion. I’ve tried to give you the big picture, with all the details you need to understand the systems, your options, and how to go about making the decisions you’re going to face along the way. With the help of some great folks – MOST notably, Noah Podolefsky, as my Technical Editor, to help check facts and flesh out concepts, I think we got it done. We have a book that, regardless of the direction you want to take your project, will point the way.

Copy downloaded :) Congrats Ted

So far I especially like the "special thanks" section. My complaints will be directed towards Noah. :D I'll let you know my thoughts in the next couple of days, but I am 100% confident it will be a wonderful read.

Rockin - congrats man.

All complaints and criticisms should be directed at Travis and / or Bruce. If Ted and I got anything wrong, I blame them :)

Are you considering a Kindle release at all?

I'm not sure how that works, but you can buy it through an Amazon retailer I think, so maybe they do Kindle? I know you can just do a download (pdf) on the Lulu site.

Thanks guys!

Noah, he threw you under the bus on the first page!!!! "If you see anything technically wrong, it’s his fault." :) Thanks for trying to keep Ted on the straight and narrow.....

Lulu special: “Enter coupon code MAYSAVE305 at checkout and receive 15% off your order. The maximum savings for this coupon is $50. Offer good towards print costs only – shipping and tax amounts are excluded. You can only use the code once per account, and you can’t use this coupon in combination with other coupon codes."

FYI, I priced the download really low... and as a token of my appreciation you crazy ElMototians, I'm going to leave the pricing as-is for a week longer, then I'm going to bring the download and Kindle pricing up to more standard levels.

Thanks again to all! Even Dave! :O
