Electrorheological Fluids

Need to do some research, but maybe this could help with braking by making breaks that are only temporarily solid? Oooh... or maybe fill the tires with it so that if it detects a leak, it can temporarily become solid? Ok, that might be a bit overkill.

Samsung's 64-GB Solid-State Drive

A solid-state drive might be a good choice for any embedded computers...

Samsung says the device can read 64 MB/s, write 45 MB/s, and uses just 0.5 W when operating (0.1 W when idle). In comparison, an 80-GB 1.8-inch hard drive reads at 15 MB/s, writes at 7 MB/s, and consumes 1.5 W when either operating or idle.

"A very fast booting embedded system like a Car computer."

Could be a useful approach.

Self-Parking Legos

If Legos can do it, so can our car :)

Some links

Federal Motor Vehicle Safety Standards and Regulations Oregon does not seem to require anything in particular -- but they will require a VIN inspection if they think the vehicle does not meet these standards.
PART C - INFORMATION, STANDARDS, AND REQUIREMENTS Not sure if this will be helpful or not.

ASSEMBLED, RECONSTRUCTED OR REPLICA VEHICLE CERTIFICATION Not sure if that form will be appropriate or not...

Street Legal?

What does it take to qualify as street legal? I assume you'd have to get the license plate, have air bags (or something), etc... but what are the actual requirements? How do we find out? Do we wade through all the DMV logs? Is there an easier way?

Oregon DMV 2005 Vehicle Code Book

While it is hard to narrow down specific requirements because of things like the law stating that a standard must be made (but not what such standard is) there are specific comments about EV.

Page 23 of Chapter 815 (Vehicle Equipment Generally) says in 815.300#9 that EV are exempt from the pollution control system requirements.

I did find some more information in Chapter L. Vehicle Types:

Passenger vehicles are titled using the VIN from the frame (or an MCO if it is a New Passenger Vehicle).

Electric vehicles are registered as per ORS 803.420
(looking that up, it is $27/yr)

Electric vehicles are subject to residency/domicile, financial responsibility, and odometer requirements. If a vehicle is manufactured without an odometer, the Exemption from Odometer Reading Requirements, Form 735-6745, must be completed. Electric vehicles are exempt from DEQ requirements (ORS 815.300)

ECU: Engine Control Unit

Howstuffworks points out that the ECU in most cars is only 40-50MHz. Since we do plan to add quite a bit more functionality, I think we should go with something faster - though preferably something low-power that stays pretty cool. In fact, we may want to consider having more than one CPU so that it can fail-over if need be.

Newer cars use the CAN (controller-area networking) at up to 500Kbps. These modules might send data over the two wires hundreds of times per second. Maybe we should use something newer. Maybe a multicast approach would allow modules (like HUD/dash modules) to auto-respond to what the other modules are reporting.

Maybe we should start with Open Cores, Open SPARC, or something similar. In fact, an OpenBIOS and OpenBoot/OpenFirmware approach could be very interesting when most of the devices are car modules.

A Better HUD?

So one of the ideas that I have played with over the years was having some of the information actually displayed on the windshield instead of in the dash. I mean, why should I take my eyes completely off the road to see if I am speeding? Or even better, why should the nightvision that shows me I am about to hit something be placed in the console of all places?

With advances in OLED and transparent transistors, maybe we could have a thin layer over our window, completely transparent, but that is able to overlay details, nightvision, etc for us. If we had this technology in place, I am sure our car computer (and a few new sensors) could really create something interesting for us.

In fact... If the engine isn't in the front... and if the dash has no gauges... maybe the windshield should be taller and get rid of the dash (for the most part)? Maybe that should be revision 2.

Reserve your Tesla Motors



Well, the 2007 Tesla Roadsters are already sold out, but if you have $100k, you can configure and reserve yours now... $50k deposit if you want to be next in line; $30k deposit if you want to let others cut in front of you. Wish I could afford one.

Potential Car Toolkit Items


























First, how about a reusable flare (or 2 or 6)... Only downside is that they use 2 AAA batteries... hope you have some charged... Actually, our EV should keep a "set" of batteries charged at all times for just such things.



And how about a couple wrenches for working on the car?



Or maybe we would rather not stand in the rain to give someone else a jump (or get one ourselves)...



Maybe we would rather not have to expend any energy to determine if the tire pressure is at 32 psi or at 36 psi?

Now this one we will skip though - cuz we are going to have heated/cooled/massage seats... who was it that does it now? Lexus or someone?





This could be... well.. fun. I mean, what would you want your car to say if it could change on a whim?



If we could find a good space for it, this could be a good emergency item.

This could make it easier to see when working on the car... but... we should TRY to design the car not to need something like this...





We probably could do with a built-in unit, but... a wireless temperature and compass could be OK...




Ok, this and might be going a little far ;)
