Got Off Highway Motorcycle registration for my electric dirt bike as well as LICENSE PLATES!!! MN just made it very easy to plate an off road bike. Now I just have to put it all back together and mount headlight/taillight.

Showed off the GSX-E at the Electric Ride here in Boulder. It's an EV event that's traveling around the state. Got to talk to lots of cool folks, including a local Zero dealership. The new S is pretty sweet - it's smaller and ligher than I expected (I didn't get to ride it though).

Made the local news: http://www.coloradodaily.com/news/ci_20647610/boulder-celebrates-first-electric-vehicle-day-expo#axzz1vBl3O4Ow

Also saw a Tesla Roadster, Fisker Karma (which is friggin beautiful), a Volt, Leaf, a guy who built an electric tractor, and a local company that builds UPS van sized EVs with a 100 mi range (Boulder Electric Vehicle). The guy was really cool, said he'd destroyed over $250,000 worth of batteries (including Kokams) in testing. He was pretty down on lipo because of the safety issues.

How long does it take you to charge from one of those 120-watt household outlets? :)

Seriously, looks like it was a cool event.

sigh...some things get lost in translation to reporters.

it was super cool. I still can't get over how awesome the Fisker is (even if it isn't 100% elecric and only has a 50 mi electric range).

Am getting ready to show the bike at Maker Faire San Mateo tomorrow (Sunday)

If anyone is going, I'll be in the TechShop area pretty much all day tomorrow. The TechShop people want the folks showing their projects to be working on their project, so I may have my bike mostly disassembled so I can get the battery packs out to check the tightness on the battery screw terminals.

I put my Zero on display at the local high school car and tech show. Lots of cars, not much tech. In 6 hours, I had two people stop by and ask what kind of motorcycle the Zero was. Upon telling them it was electric, they moved on to the adjacent Dudley Perkins Harley pop-up where they ogled the two bikes on display and talked to the salesman for a while . A few photos are attached.

That's too bad. Most of the people that see my bike ask about it and are interested, even if not quite to the point of writing Zero a check.

That gas hub motor, er, tank, is interesting though.

Certainly should be! I might finally be able to do a burnout :) Those lead packs really never had me satisfied.
will be 88.8 nominal, 60Ah (i overpurchased by ~10% in case of bad cells)
voltage is a bit higher than the components are spec'd for, but if i cap the charging at <4.1v/cell i think i should be fine.

also very excited to use a set of these (URL http://www.methtek.com/category/battery-protection/ (http://www.methtek.com/category/battery-protection/)) battery protector circuits, so it DOES NOT go up in flames... and oh the wiring trouble they will save me

Got good news from Davide @ Elithion: He added support for limited OBD-II PID's.... and has it working with Torque for Android via a bluetooth to OBD-II dongle (should also work with Scangauge and other OBD-II readers if you can enter custom PID's). Just need a firmware update and I can do some testing. TOTALLY opens up a new world for gauges and logging.

get a CBA and do discharge tests. Pretty much the only way to weed them out is to look at sag at a certain current and compare. Or at least measure IR (which for DC OS about the same procedure).

First Ride today (with EV grin Ted)! It's not pretty yet, like a Noah build, but it works! I was pleased by the performance with the Alltrax SPM controller set to max out at 200A (until I do some heat testing). After spinning the rear wheel on the Centerstand for a moment I was dying to feel it work so I grabbed my coat and helmet, yelled at the wife and kids to get a camera and rode it out of the garage it has lived in for 5+ months. The first throttle action feels delayed but predictable/reliable so I could burst down the street, cut the throttle and hit the brakes hard, bank for a tight corner that needs power to sustain, crack the throttle and wait with confidence it will pull out of the corner. The SPM was set to a battery overvoltage threshold of 62V out of the box...had to change that. I'm looking forward to experimenting with the throttle curve programming!

billmi
22 July 2012, 0925
Ted, I just borrowed to try out. It's interesting, but it's pretty much a one-trick pony novelty at this point (low final resolution, pretty light hungry, limited dynamic range, very limited control). Even as they improve features of processing the data to build an image, I think the real applications aren't going to be in consumer and traditional professional photography, but rather technical photography like manufacturing process control, forensic analysis, 3d scanning, visual effects, space exploration (where reducing lens weight and size matters), etc.

Zoomsmith - most definitely it's always fun to see what new technology can do.

teddillard
22 July 2012, 1022
Cool... I've been following the development of that since Bill Atkinson mentioned it when I was at his studio. (Yeah, the Apple/Color Management Guru Bill Atkinson, name-drop FTW). He called it the bug-eye camera. Basically, a camera that works on the same idea as a bug's eye - millions of tiny apertures.

When the photos started coming out, I was all over it, until I realized it got pretty boring pretty fast. Even the shots you'd think would be really cool - a line of awesome models looking awesomely hot, with awesome things going on around them - kept my attention for about a nanosecond. Not sure what technical applications you could use it for, that a high resolution sensor at a small aperture with a kickass lens couldn't do better.

Still- a fun toy, and I wouldn't throw it out of bed for eatin' crackers. :D

Kinda like when Maurice Gibb introduced himself to my wife and I as a big fan of ours (well, not like that at all, other than being a name-drop :-)


He called it the bug-eye camera. Basically, a camera that works on the same idea as a bug's eye - millions of tiny apertures.

That's how the early ones were set up. These days they're integrating the aperatures on the sensor, and still using a single primary lens(s) in front of the array. I think the description that's made the most sense to me, is that it's gathering raw light data, then using computer modeling to simulate the adjustable elements (iris, focusing and or zoom elements) in a traditional lens and build an image from that.



When the photos started coming out, I was all over it, until I realized it got pretty boring pretty fast. Even the shots you'd think would be really cool - a line of awesome models looking awesomely hot, with awesome things going on around them - kept my attention for about a nanosecond.


Yeah, that's what I mean by one-trick pony - first you've got to compose your shot where depth of field is a big deal to the shot, then how long do people have interest in adjusting depth of field on a picture they didn't take? It's a neat trick, but then what? Lytro's sales pitch acts like it's a revolution because you won't have to worry about out of focus shots - but really, for consumer cameras that all have fast auto-focus, how much is that a problem vs. decent lighting or not exceeding the dynamic range of the sensor?


Not sure what technical applications you could use it for, that a high resolution sensor at a small aperture with a kickass lens couldn't do better.


With light field imaging (not just with what Lytro's camera and software do):

Microscopy - With the long focal length you have almost no depth of field, shooting pictures of cells, you've got to choose what layer to slice them at (literally, the foreground and background are so blurred away at 800x that you photograph right through them). Getting the light field you can focus and composite the data, effectively broadening the depth of field.

Parts inspection / forensics - you can generate a depth map from the light field data - imagine how much more effectively a computer could match ballistic scratches on a bullet if it were matching a 3D shape, not just a 2-D image, or analyze a crack in a steel beam. Consider a half-dozen photos of a crime scene, or insurance investigation that contain enough data to have a virtual reality walk-through of the scene, or provide a virtual tour of a museum.

Aerospace - Replacing a lot of glass lens elements with software is weight savings.



Still- a fun toy, and I wouldn't throw it out of bed for eatin' crackers. :D

I think that well describes Lytro's camera. It's more a curiosity than a tool. If you haven't seen it, check out Raytrix.de - they've had their cameras on the market longer and are more oriented towards industrial applications.

23 July 2012, 0237
Yeah, kinda like when I ran into Steven Tyler in the men's room and he shook my hand for being so awesome except for the part about not washing his hand first. (eeeeeew, FTW)

Well, I'm reminded of Mark's signature about the not bending the Laws of Physics, so I'm going to prolong this off-topic topic... :D

There's no magic here. It's simply using the advantages of a very small aperture, almost a pinhole, to minimize the depth of field problems you get with an optical lens. Optical lenses simply are devices to gather more light, compensating for small apertures, right? So they start with a bunch of small apertures that focus the image to a bunch of small sensors, and get the same high depth of field you get with pinholes, or point-and-shoots, or even phone cameras. That cuts down the light, (you've traded dynamic range for "focus") so you push in an optical lens to gather more light, and hopefully give you more dynamic range...

All that "Light Field" hoo haa is just marketing blather, you can't escape the fact a camera, any camera, is a box where you hold the lens (whether it's an optical lens or a pinhole) in one place, and a sensor (whether it's a chip or film) in another. Light Field is just another name for, essentially, a bunch of really small cameras taking a whole lot of crappy shots at once and then putting them together to get one not-so-crappy shot. I can't figure an application where one good lens and one good sensor can't, in some configuration, yield a better image, and I can give you specific configurations... for microscopy, for example, simple image stacking software seems far more practical.

There's no 3D thing going on here, either. All the shots are being taken from essentially the same point in space, or, at best, microns apart, so any parallax information is far from what you could gather with a simple stereo array or actual 3D scanner.

...it all reminds me of those snapshot cameras with tiny small apertures that they sold as "autofocus". It can't be autofocus if the lens can't move. :D

...anyway, I'd be glad to take this up on, oh, Luminous Landscape with you if you're game. :o

It's been awhile since I watched their video, but I think one of the things their microlens sensor array allows is recording of the incident angle the light rays impinge on the sensor at. Then the software can sort of back-calculate the image at different distances using what I assume to be ray-tracing techniques or something similar. This would explain the low final resolution and light insensitivity, as only a fraction of the sensor's pixels record the part of the image you're interested in.

It is cool, though.

Raytrix is being very misleading about their products then: "Only one snapshot is required for the Raytrix camera systems based on light field technology to calculate 3D depth maps and multi view perspectives."

Yes, I believe they are. Here's some more reading about the so-called light field camera technology, for those interested:
http://en.wikipedia.org/wiki/Light-field_camera

...it's really nothing more than a glorified stereo camera, but with a very small amount of parallax offset, and a whole lot of software amplification. The original definition of light field, back in the thirties, was a little more true to the physics of light. The current use is more true to the marketing of the product.

Sorry, I've seen a whole lot of blather for over a decade now about the next technology revolution in photography, and it all comes down to what we deal with here... the basic realities of Physics. You can do a whole lot with a very little bit of information using software, but time and time again, it's been proven to me that if you start with good, solid data you can do a whole lot more. Remember the Foveon sensor?

Sound familiar? Next generation batteries producing twice the power in half the weight for 1/4 the cost? Motorcycles that go incredibly fast with amazing range for prices below anything we're seeing, but are still "in design phase"?

Have I become bitter and jaded in my old age? :D

A bit beyond stereo, in that it's also got separation on the vertical axis as well (quadrophonic!) but if that's all they're doing, I agree - it's a good move forward from the Stereo Realist my mother used to shoot but there's nothing revolutionary there.

Yep, with all of those things - you never really know what the winners are until they've had their day out in the real world to either prove their worth or lack thereof.




And to not just talk about gadgety cameras - what I did today - was ride an electric motorcycle in the rain for the first time.

I haven't waterproofed everything so I've avoided the rain, and I expect a serious deluge might pool water on top of my top battery pack - pooling on the MiniBMS boards would not be so good. But, my controller is waterproofed and everything is pretty much splash resistant, and when I ran into some rain a few blocks from home (we get *very* localized rainshowers - it can be pouring in one neighborhood and sunny in the next) I kept going. I rode on through and everything was fine.

Well yesterday I had the engineer over to look over the bike and ensure I am on the right path. I was a little concerned that he might not like the way I had done some of the things. He got me to prove the new brakes were pulling up the bike in a suitable time (great fun on a wet and cold road), inspected the battery mounts and looked over the job.

No need to be concerned, he gave me a short list of items that I must do:

Get the tare weight of the bike measured at each wheel
Fit ADR (Australian Design Rules) approved indicators
Get and fit a mechanical battery isolation switch
Place a warning sticker on the brake reservoir
Provide a space for the modification approval sticker.

Admittedly there is stuff I have to do prior to final signoff that were already in my plans:

Polycarbonate protector plates on the batteries
12 volt wiring and fuse box
DC-DC convertor installation
Water cooling setup.

Given enough weekend time I plan to have this done by mid October at the latest.

Gotta say... this is the cutest camera I've ever owned. Honestly, for what they are, and especially the price, they're awesome.

I've stayed away from them because you can do pretty much the same thing with almost any point-and-shoot though, and a whole lot more, but the single-purpose design makes it pretty effortless if you don't want to fuss with stuff. Also, for most cameras $130 would barely cover the waterproof housing.

Ebayed a tank (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=281012483686&ssPageName=ADME:L:COSI:US:1123) for my build for 20 bucks! It needs some work , but should cover my electronics nicely when it's done.

Noah, glad you're going to be OK, I'm lucky, I have only ever gone down (knock, knock) on a dirt bike, with soft dirt or grass to cushion my fall. Once quite spectacularly over the handlebars, but into 5 foot tall grass that gently caught me, and my bike. (which was nice because there was a rather ugly, steep rocky cliff on the other side of the trail!)

Just a few inexpensive motor parts at the impact point...that's a testament to good design. Let's all take a look at our builds and imagine the impact from even a low speed crash and its' effect on the battery system, bus bars, cables, fuses and potentially impinging metal structures. How safe is your design and how would you inspect it after a drop or accident before pulling it into the garage for the night? How would someone unfamiliar with your bike (fireman?) turn it off and make it transportable?

Everybody who's put in serious miles has gone down...sorry you were injured Noah!

Front fork tubes had rust pits that wipe out seals. Today I bought used forks to tear apart and grab the inner tubes from when I get a second.

Luck mostly...if it was the left side, would have hit the cells. Hard to say how much damage that would have caused.

I've thought about frame sliders to protect the pack. Going to consider it more seriously now.

Turning off the key or run switch kills my system, just like any ICE bike. A full pack short is unlikely, but not impossible in a bad enough crash. Pack fuse would save it though. Of course, anything can happen, but I consider chances of a dangerous situation far less likely than an ICE bike catching on fire in a similar crash.

...don't really want to think about that though.

The motorcycle is naked right now so no photos please.....and certainly no evidence of anyone riding
a non-licensed motorcycle on a public road.... ;)


it is interesting on how Kelly (maybe others) rate what amps you get at a certain percentage.

It looks to be exponential. 70% on the 600 amp controller (same brand/type) gives me 420A.
70% on this one gave me about 600A? That last 5% must be a mother.....

Now granted I am only moving a 350lb (at the moment) bike with a 195lb rider so the load detection
of the controllers will be different.

induction motor ... you can even drive it with the curtis :D :D
the only drawback is that Curtis can only generate up to 70V AC instead of the 380 required by the spindle so you will have much lower power , but Curtis can do up to 300Hz so RPM will still high.

'cuz when i was running the Kelly controller, the controller needed to be on a separate, floating 24V circuit (floating from the pack and also floating from the 12V system too). With the change to the sevcon, the arduino needs to be on a circuit that has a common ground to the pack, so i was planning on re-using the 24V circuit and then attaching the ground from the 24V circuit to the pack.

Front end frame section and control arms of the reverse trike street rod bolted up for a test-fit. Decided to build front, center and rear frame sections, with a separate body instead of everything built as a monocoque structure as originally planned. The three frame sections will give some modularity and tune-ability to tweak out any issues with alignment if needed.

Front springs/shocks will be air adjustable Shockwaves from Ridetech - basically a QA1 shock with an air spring build around it with adjustable spring rates AND damping rates.

Every square inch except for the steering spindles, ball joints and wheels is carbon fiber.

Thanks ARC! Target weight is 600-700lbs. We'll see how it ends up because so far I have 130lb into the battery pack (96v 60Ah Headway) and 200lbs into the total carbon/epoxy weight of raw materials stocked for the project. Between the motor and electronics, brake/steering systems and other running hardware, I don't think Im going to hit the target... but I WILL have one NICE daily driver hot rod regardless. I'm also building in provisions for relatively easy battery expansion and motor upgrading because knowing myself, I'll end up doing that at some point anyway.

Love the feel of big wires and carpet Travis! When I first developed the algorithms for the Amp-Hour Meters, Link-100, 1000, 2000 and E-meter products I was astounded by how little work had been done to characterize a complete cycle. Peukert did the best discharge work for lead acids...in 1897! But nobody looked at the entire charge discharge cycle in a real application and applied that to State-Of-Charge (SOC) estimation. You have some nice tools, don't set the apartment on fire, learn a lot, and create a new understanding of SOC for exotic battery chemistry!

I was on a fun ride at the end of the day, ripping up the steep hill out of Edmonds at 40 mph and a chilly 42 degrees, rolled a California stop and the bike shut down. Coasted to a driveway and up onto the sidewalk. E-Meter was still on and pack voltage was okay...no headlight means no 12 Volts! I gave it a once over but all looked good, nothing loose, no blown fuses.

Phoned home and my wife was there. She grabbed tie-downs, the ramp and brought the pickup. Thank You!:)

Once I had the bike in my shop a quick test showed that the 12 V DC/DC Converter was well fed and enabled but not driving a load. I unplugged the load and the output went to +13.5 as designed. I am using a Vicor VI24P with a BUS adapter that allows me to use screw terminals on a PC pin device. The +V output pin had a cold solder joint that looked pretty good, but not great. Heated it up and all is well and riding again!

Thanks guys! I spent a good part of the afternoon in the twisties. Working on a writeup....

The tail is a bit long, But I think it's a legality thing that it has to be positioned over the wheel or something. Brian has a Tail Tidy mod... so I may do that. Gonna get some Spools and maybe a flyscreen for it, but nothing really needs to be added to it IMHO.... it's great out of the box (or in my case, back of a Brammo van).
