Cool airplane-based 3-wheel vehicle build on Hemmings

Posted on

Stumbled on a cool airplane-based 3-wheeled vehicle build on the Hemmings blog tonight, and it’s for sale.

This thing is really friggin cool. Execution of the nose is a bit weak, but… I really like the layout.

Now I want to find a damaged four-place single-engine low-wing plane and do that myself. Two ways to get reverse, really – use the GL1500 drivetrain like that guy did as-is (I’d want Megasquirt and taller gearing, though), or do a through-the-road hybrid system with the hybrid system on the front wheels, and implementing reverse. That allows one to use the GL1200 fuel injected driveline instead – less displacement, lower cylinder count, etc., etc.

With a GL1500 megasquirted, I’m thinking it’d get around 70-75 highway, 40-50 city.

With a GL1200 FI and a hybrid system, 75-85 mpg highway, 60-90 city depending on how well the hybrid system is tuned.

Weight would be in the 1200-1500 pound ballpark I think, both engines are in the 90-100 hp ballpark (the GL1500 was all about more torque), so you’d be looking at 0-60 times in the 5-7 second ballpark, top speeds probably 140-150 mph (quite low drag), although you won’t want to go that fast.

And, it’d be a more practical layout than my main 3-wheeler project idea if executed properly – 4 seats plus some (not much) cargo room, instead of 1 normal seat, 1 barely usable seat, and less cargo room. Downside is, production would be less practical – it ain’t cheap to build things this light new. Piper wants $301,500 for an Archer TX – even if you go with the “half of the plane price goes to the lawyers” rule, and even if you knock $100k off for not needing all the FAA certs and the Lycoming engine and all, you’re still looking at $50k.

Thoughts on my three-wheel vehicle project

Posted on

For a while now, I’ve been planning a tadpole (also known as reverse trike) three-wheel vehicle that would have tandem seating, an enclosed cabin, and would achieve 156+ miles per US gallon on the highway by using a diesel engine.

I’ve even bought a 654 cc twin-cylinder Ruggerini diesel engine for this project. Here’s the problem though.

That diesel will get me in the ballpark of 16-20 hp. While that will be more than enough to achieve cruising speed, 16 hp won’t get me acceptable acceleration, and even 20 hp will be painful. In addition, the driveline will be rather long, due to having the transmission behind the engine (and a fair distance away to avoid fouling the oil filter), and then the rear wheel behind that.

So, my question to you is… should I abandon the diesel route, and go to a 300 cc single-cylinder fuel injected gasoline engine from a scooter (which means CVT)? Continue reading “Thoughts on my three-wheel vehicle project”

Proposal: Let’s create a successor to RIAA Radar

Posted on

For those unaware, RIAA Radar was a tool that Ben Tesch wrote, that made it very easy to determine whether a certain piece of media was released by a RIAA member label, to assist with boycotting the RIAA. It worked by searching Amazon for the search term in question, and returning all CDs that met that search term, along with the label that published that CD, and a simple “safe”, “unknown”, or “warning” image based on whether the label was a RIAA member or not. Unfortunately, due to maintenance and hosting issues, he took it down.

However, I feel that such a service is still extremely useful today, and in fact, should be extended to other content industry organizations, such as the MPAA. Continue reading “Proposal: Let’s create a successor to RIAA Radar”

Why long haul trucking is an awful idea, and rail is far better for long-distance transport

Posted on

Semi trucks are a common sight on American roadways, crossing the country, delivering goods quickly.

However, they’re actually a huge problem for our economy. They put tremendous strain on our infrastructure (and they don’t pay their way for their damage to our infrastructure), they’re inefficient compared to trains, and they present a serious safety risk to car traffic.

In my opinion, long haul trucking activity in the US should be extremely reduced. Read on for why that is the case. Continue reading “Why long haul trucking is an awful idea, and rail is far better for long-distance transport”

Warning about the WIMM One’s EULA

Posted on

So, I just got done with my smart watch series, and decided to sign up for the WIMM Labs site, and maybe purchase a WIMM One.

I was presented with a EULA, not entirely unexpected given that their site provides private downloads of things like the SDK.

Occasionally, I actually read EULAs. There’s an annoying reverse engineering clause, although it’s fairly toothless. The clause that really bothers me, though?

CONFIDENTIALITY: You acknowledge and agree that the Software and Hardware were developed at considerable time and expense by WIMM Labs, and are confidential to and a trade secret of WIMM Labs and/or third parties. You agree to maintain the Software and Hardware in strict confidence and not to disclose or provide access thereto to any person.

So, you’re telling me that, even though I can buy the damn thing for $199 on Amazon, I can’t show it to anyone else or let them use it? Really, WIMM?

Therefore, I decided to buy a refurbed Abacus Wrist PDA – I had one a while back and it died, but IMO it was a brilliant device, potentially the best smart watch even by modern standards (except for not being able to get alerts from an Android device). I’d be willing to consider the WIMM One if they revised that portion of their EULA, but not before then.

I’ll post the full EULA text after the break – you get it after signing up for the WIMM site, and if you simply buy the device without signing up for WIMM’s site, you don’t see the EULA at all until you’re setting the watch up. Continue reading “Warning about the WIMM One’s EULA”

The history of the smart watch, part 4 – the modern era

Posted on

Finally, we’re to the modern era of smart watches – stuff that’s actually for sale today.

Most of the modern smart watches all connect to a host device via Bluetooth (with one exception), at least an Android device if not additional platforms, for notifications. Some act as dumb terminals (along the lines of the Abacus/Sony watches mentioned in the previous post), whereas some have some local processing power and even apps (some running Android).

The history of the smart watch, part 3 – SPOT, PDAs, and bluetooth

Posted on

So, after moving my blog entirely from My Opera to a self-hosted WordPress install (I’m not done migrating the older entries, I’m partway through 2006’s entries there), I think it’s time to continue this series.

Last entry, I left off in the mid 1990s, with pager watches and the odd databank watch. But, for the most part (with a couple exceptions in the mid 80s), watches haven’t actually been “smart” yet.

We’ll begin where we left off, and continue with the second start of true smart watches – watches with data storage, local processing power, and arbitrary code support. Continue reading “The history of the smart watch, part 3 – SPOT, PDAs, and bluetooth”

The history of the smart watch, part 2 – storage, programmability, multimedia, and communication

Posted on

Yesterday, I covered the history of the smart watch from the 1940s slide rule watch, to the 1970s calculator watch, and dipped into the 1980s with musical and gaming watches.

However, while some of those watches had processing ability, it was very limited, not programmable, and transient – once you were done processing data, you got back to the clock functionality, and whatever you were doing was gone. But, with Japanese electronics makers competing, some real innovation started. Continue reading “The history of the smart watch, part 2 – storage, programmability, multimedia, and communication”

The history of the smart watch, part 1 – calculation and entertainment

Posted on

With the recent development of so-called “smart watches”, designed to communicate with modern smartphones to display notifications, and in many cases run various applications on the watch, I felt that it would be a good idea to document the history of the smart watch.

After all, the modern smart watch is far from a new idea – watches that could run user-installed software have existed since Seiko’s Wrist Information System in 1984, and notifications have been pushed to watches since Seiko’s Receptor in 1990, and Swatch’s the Beep in 1991.

I’m going to stretch the definition of smart watch a bit for this history – the definition I’m operating under is something like this: “A watch that has functions in addition to timekeeping-related functions, such as calculation, data storage, scheduling beyond an alarm, ability to load arbitrary code, music (beyond alarm tones) and/or video playback, or reception and/or transmission of radio signals for functions other than setting time.”

Also, due to the existence of various devices that have watch-like form factors, but are not meant to be worn as watches, I’m going to restrict this discussion to wrist watches. Continue reading “The history of the smart watch, part 1 – calculation and entertainment”
