The AutoCanoe

August 26th, 2007

Here’s another unique pedal-powered machine; the AutoCanoeTM.

The Autocanoe Is a Pedal Powered Amphibious Recumbent Tricycle and a Roadable Pedal Canoe! The configuration is that of a Recumbent Tricycle with the two forward wheels driving and the single rear wheel steering both on land and in the water. It can travel over the road and through the water with comfort and grace. Transitions from land to water and back are accomplished smoothly and seamlessly without leaving your seat. On the road it is stable and secure. On the water it is tractable and relaxing. This human powered vehicle appeals to bicycle enthusiasts as well as wooden boat fans.

It was built by some guy in Washington state; he thought it was a great enough idea that he trademarked the name and is selling plans for $30 a pop. The thing looks like it’d be kinda fun on the water, but getting anywhere on land would be difficult. It’s got to weigh a ton, and can’t be very maneuverable (or very fast). Look at that front overhang; you’d almost have to build a steel plate into the prow of the thing for all the approaches you’d be smacking into.

BECAUSE I SAID SO

August 26th, 2007

Another neat find from Neatorama; BECAUSE I SAID SO. A mom’s blog expressing the frustrations of child rearing (suppose that term was coined by the spankings that are applied when said children misbehave?)

The blog is very well written, and unlike a lot of blogs, is very unassuming and innocent in what is posted. Most blogs seem to be written to gain attention, because it’s the cool thing to do, to make money, (is my blog different? I hope so.)… I guess the word I’d use is unassuming, or maybe unpretentious. Dawn seems to write just to get things off her chest and was truly unprepared for all the attention she’s now getting. And the attention started when she put a baseball up for auction on eBay using the story behind how the baseball kicked off a terrible, horrible, no-good, very-bad day for her.

The Ball That Started it All

I’m selling the baseball that started my wonderful first day of spring break. Do you want to know why I’m selling the baseball that started off my wonderful first day of spring break? Only because Ebay won’t let me sell my kids who were playing with the baseball that started my wonderful day. Is spring break over yet?! Here’s the whole story…

You’ve just got to read it and laugh, because if you’ve got kids, you’ve probably had a day like that before. At least one.

Just bumped into ShouldDoThis.com this morning (thanks to a link on Neatorama). Think of it as a suggestion box for everything. Some suggestions are serious, some not; some are helpful, some naughty… But most are fun to read.

The Free LaFree

August 17th, 2007

I’ve been planning to buy an electric conversion kit for one of my bikes for a while now, and finally got the money and the CFO’s blessing last week, and ordered one. It’s due to arrive on Saturday. But that’s another story for another post, because Fortune smiled on me tonight.

Ian had a flat on his bike, so we stopped by Spoke-n-Sport to pick up some tubes tonight. I had emailed Chad, the owner, earlier asking about ebikes, so he knew I was interested. He was there tonight & asked if I had received the email he sent about the two Giant LaFree electric bikes one of his customers was looking to sell. I had seen the email, but hadn’t contacted the owner about them because I had already decided on the hub motor kit. Good thing, because the owner had bought new bikes and traded in the old ones. Chad wasn’t sure how much work it was going to be to get them running again — the owner said that one of them had a major problem but wasn’t sure about the other — so he was just looking to get rid of them. He said that if I didn’t want them he was probably just going to dump them. So, being the pack rat scavenger that I am, I couldn’t say no.

The bikes look like they’ve spent more time in the garage than on the road; a little dusty, but very little wear on anything. The burgundy one is missing the bottom plastics, and by turning the crank I can tell that that’s the problem child. The silver one seems to be ok. I plugged the batteries in, and they appeared to be charging; so far so good. Then, on a whim, I check the batteries just before bed, and one is showing a green light — charged. So, on another whim I pop the battery into the silver bike; nothing. Pop it into the burgundy bike & fiddle with the key and I get what sounds like an error beep and one LED lit on the battery level indicator. Pop it back in the silver, fiddle with it’s key, and get full battery lights! Cranking on the throttle doesn’t do anything, so on another whim I roll it to the driveway & hop on. And whaddyaknow! It works!

This is the first time I’ve ridden an electric bike, and the first time since 1986 that I’ve ridden any 2-wheeled conveyance that isn’t powered by me, so it was great having the wind in my hair again. I’m glad it was 11pm; the darkness hid my ear-to-ear smile from the neighbors. The ride was great. Went around the block a couple of times & discovered that the motor only engages when the pedals are turning. You don’t have to be pushing to get it to engage, only a token spin is required. And because the motor is ahead of the crank, it drives the chain, which also uses a standard 7-speed freewheel; that allows the motor to work in conjunction with the gears. Gear down to go up hills, and gear up for the flats. Pedal harder to give the motor some assist to go a little faster and get a little more life out of the batteries.

I couldn’t be more pleased to have a working bike without having to fix it. The other bike I’ll keep around for scavenging or selling parts. The frame may one day be incorporated into a hub-drive electric, but that’s gonna take some work. Especially getting rid of the girl frame look. Lessee… a tube across the top and a plastic fairing in between? That might be a start.

Lightning Samurai

August 5th, 2007

What do you get when you stretch the front of a Suzuki Samurai out & stuff a 425 horsepower Corvette engine under the hood? The Lightning Samurai, built by SuzukiConversion.com. It’s apparently a one-off, but I’m guessing they could churn out another if someone were to come up with $25,000.

lightning_samurai_l-front.jpg

The car has been converted to 2-wheel drive, and also features a 6-speed Camaro transmission, narrowed rear end to make room for the extra wide rear tires & antilock disk brakes on all four wheels. they say it’ll do 160mph, and will cruise at 140. I believe it.

It looks a little funny with that extra long nose on it, but I guess the short little engine bay on a stock Samurai isn’t quite enough for the LT1. They’ve got a nice set of photos on their site — I nabbed them just in case they sell the thing & take down the pics — but I’d sure like to see what it looks like with the top off, since that’s the way I’d be driving it.

The VogaBike

July 31st, 2007

A couple of weekends ago I bumped into something online that made me dig up some sketches I’d made years ago (1985 or ’86 I think). Back then I was wanting to build a record-breaking human-powered speed machine. I reasoned that the pedaling action on standard bikes was less than efficient, but the rowing action would allow the power of the legs, back and arms to work in unison to generate the horsepower to scoot along at much higher speeds. Of course, in rowing there is a return stroke that nullifies some of the efficiency gains, but I think that putting the back and arms into the mix more than compensates for the momentum loss in the return stroke.

Back then, the incentive for the project was a contest promoted by a magazine (can’t remember which) that offered a $10,000 award to the first person who could hit and sustain 60mph in a human powered vehicle. Being newly married (or about to marry… Can’t remember exactly), and about to quit my job to start college, that cash would’ve been great seed money. Unfortunately, life got in the way, and the prize money was claimed long before my ideas even got off my sketchbook.

I still think the rowing motion has a lot more potential for speed than pedaling, and I’d still like to revive the idea and build a row-powered bike, just for fun. Digging around a bit online led to the realization that my idea is not original, and others have actually built such creatures, some being mass manufactured & marketed. Of course, some embodiments of that idea are better than others, and some are just downright screwy. One of the better ones that Google brought to light for me is the VogaBike. This machine is truly brilliant. The Italian geniuses at VogaBike seemed to have come up with dead-simple solutions to a lot of the problems that I had encountered in trying to design a row-powered bike.

So slick I just might have to borrow a few of their ideas. 😉

This Message Will Self-Destruct In 10 Seconds

July 30th, 2007

willselfdestruct.jpg

Here’s a service I’ve wished for on a number of occasions; WillSelfDestruct.com, where you can send an anonymous email that can only be viewed a specified number of times or for a specified amount of time. You just enter the recipient’s email address, a subject, your message, and how you’d like to have it viewed. You can also enter your name, or an alias if you like.

When you hit Send Message, it goes to the recipient, who gets a link to a web page containing your message, along with a counter telling them how long it will be available. Through some kind of trickery, the text can’t be copied or printed. Pretty slick. Might even make them wonder about their sanity.

Not that I’d ever use such a service or anything. Nope. Not me. Maybe my evil twin Skippy, but not me. Nuh-uh.

The RoadBoat

July 25th, 2007

Here’s an interesting human-powered vehicle. Christened the RoadBoat — a cute play on names, since it’s powered by four “rowers”, but travels on the road — it was designed and built to set a record for a trans-Canada ride back in 2001.

roadboat_lr.jpg

We intend to establish a Guinness World Record for traveling from Halifax to Vancouver using only the human power found in a rowing stroke (plus the mechanical advantage of gearing, of course … )

Apparently things went awry early on, and the team decided to bag it. One of the rowers, Kevin Thompson, had this to say about the attempt:

After traveling through the province of Nova Scotia it was determined that the record would not be broken due to lack of averaging an adequate speed to complete in record time. Subsequent to the first day mishap which resulted in a minor accident, the RoadBoat was unable to achieve the necessary average speed, safely, to complete the crossing and it was therefore decided to end the journey early.

Funny they don’t mention anything about that first-day accident on the RoadBoat 2001 rowingacrosscanada.com website. The failure probably stings a little still. The current site, www.rowingacrosscanada.com, is still active, and it looks like a second attempt may be in the works, but there are no details at all. Makes me curious what kind of monstrosity they’ll build for that!

I stumbled across this looking for info on vehicles that are propelled by a rowing motion. While a bit extreme, this thing is kinda cool. There are also a few photos of the building process here. Not much detail, but it looks to be built from all aluminum tubing. And to support four rowers and a stoker/steerer, it’d have to be pretty beefy.

The MI Speedball

July 22nd, 2007

mi_sept_56_cover.jpg

I’m not quite sure whether to poke fun at this idea or applaud it for being a great idea. In 1956, Mechanics Illustrated published plans to build a car from mostly plywood, oak, and mahogany strips, using a motorcycle engine for power. On the one hand, I love the concept; light weight, readily available parts, build it in your garage…

But on the other hand, this thing — as designed and described in the article — has some serious issues. A frame made from oak and plywood? Can you say “severe body flex?” And the brakes… The motorcycle rear hub mounted inboard with a welded shaft going to the left rear wheel? The whole frame & drivetrain seems pretty lacking to me.

I guess the appeal for me is just that it conforms to some of the basic ideas that I’ve had for a project of this kind that I’d like to put into flesh someday; using off-the-shelf or salvage yard components to build a zippy little two-seater like the Locost or Stalker V6. But using laid up cedar for the body panels… That just may have some possibilities! But I’d definitely forego the wood frame. Definitely.

One of the neatest features on the Speedball is headlights that lay back for aerodynamics, but snap to attention when you pull a lever. And that’s not all; when in the upright position, the right headlight pivots in concert with the front wheels to throw light in the direction you’re turning. Not sure how steady the light would be on this buggy, but it might be an interesting feature to commandeer. Then again, would it really be worth the amount of work it’d require? Maybe not.

The Modern Mechanix Blog has high-res scans of the pages, along with an OCR’d version of the text. Here also is a pdf of it.

The Digital Movie Experience

July 21st, 2007

christiecp2000.jpg

A couple of weeks ago Caleb and I went to see Ratatouille (great, great movie, by the way), and much to my surprise the theater (the Carmike 7)had installed Christie digital projectors. Wow! What a difference that made! The colors so bright, the details so crisp… Everything was just so… clear. Add to that the elimination of the little signal blip (or whatever they call it) that tells the operators when to switch reels, and the elimination of the annoying little dirt specks you see on the screen.

I realize the digital theater projectors aren’t all that new, but I don’t get out to movies very often, and that was my first exposure to it. When I first heard about them I thought, “oh, no big deal”. But after seeing it for myself, all I can say is, “Wow!” It’s like the difference between an old CRT monitor on a scuzzy old PC and a snazzy new 24 inch iMac. There’s just no comparison.

Tonight, Ian & I went to the Century theater to see Transformers (should’ve waited ’til it hit the cheap theater). I was hoping the Century had also updated their projectors, but they’re still using film. They still charge more than the Carmike though; go figure. The difference was was a real letdown after Ratatouille from a digital projector. I am forever spoiled.
