OScar (open source car) Design proposal: 4 wheeler Exploded view: 3 wheeler OScar is the first attempt to design an entire automobile using open-source principles. The aim of the project is mainly to produce blueprints, using essentially open-source CAD. The project commenced in 1999, founded by Markus Merz, and launched its 0.2 release in 2006, but no further progress has been made. In 2007, Merz admitted the project was a hobby.[1] Goal and challenges[edit] The goal of the project is not to produce a sophisticated car, but rather a simple and functional basic one, which answer people's basic transportation needs. Among the challenges this car will have to overcome, before reaching the manufacturing phase, are to conduct crash tests and also to abide by very strict security legislation and pollution norms in the car industry.

The StreetScooter is a $7,000 EV with a 74 mph top speed and an 80-mile range. It relies on leased batteries and uses a heat pump for heating and air conditioning, and shipping company DHL has already ordered 3,500 of them — but the most interesting thing about the vehicle is how it came to be. What began as a partnership of 10 companies has grown to a collaboration among more than 50 auto parts suppliers, tech companies and software developers. Each one of them had a hand not only in building the StreetScooter, but in creating it. Traditionally, cars are built from a top-down approach. The original equipment manufacturer (OEM) designs a vehicle and dictates design requirements to suppliers. There’s back-and-forth, but it’s clear who is in charge. Unfortunately, the process can overlook what efficiencies supply chains offer.

In business school jargon, that’s called product lifecycle management, or PLM. “Everyone is on par with each other. Photo: StreetScooter. Cooper Union Showcases Student Innovation. Maxwell von Stein's Flywheel Bicycle (Courtesy Cooper Union) It’s that time of year again: School is giving way to summer vacation, final reviews are winding down, and the life of the architecture student regains some semblance of normalcy.

The Cooper Union celebrates this time of year with its traditional End of Year Show, highlighting the work of students in art, architecture, and engineering. Hundreds of projects are now on display at the school’s Foundation Building at 7 East 7th Street on Cooper Square. The engineering show just wrapped up, but the architecture showcase runs through June 18 and the art school’s work will be on display through June 11. The exhibition is free and open Tuesday through Saturday from noon until 7:00 p.m.. Take a look at a few of the student projects after the jump. Engineering student Maxwell von Stein applied the principles of a hybrid car to the bicycle to harness the kinetic energy typically lost when braking.

Louis Lim's Untitled, 2011. The New and Improved Brushless Electric Scooter Power System Guide. In 2008, I put together a guide on Instructables about upgrading the power system of your small personal electric vehicle . It was a primer on the basics of an electric vehicle power system and offered resources and tips specific to compact electric scooter conversion. As of right now, it has a solid 5 rating - I didn't know you could write that much on Instructables without telling anyone how to build anything and still receive perfect reviews. I am delighted to report that in 2011, three years after the fact, that putting together a compact, powerful, and efficient electric vehicle drivetrain for local commutes (such as your campus, neighborhood, or urban area) using both R/C hobby hardware and specialized EV components is now cheaper and easier than ever.

Price competition, new technologies, and just plain increased availability of fabrication and material resources means that building an electric personal transport device is now within the capabilities of just about everyone.

Two devices will replace lead acid traction batteries. 07 Jun 2011 09:06:31 Two devices will replace lead acid traction batteries By Dr Peter Harrop, chairman, IDTechEx It is like waiting for a bus. You wait and wait then two come at the same time. Alternatives to short lived, toxic lead acid traction batteries, with their indifferent performance, have been sought for over 100 years. Now both lithium-ion batteries and supercapacitors are near to replacing lead acid traction batteries in the many traction applications where they are still used.

Popularity of lead acid Lead acid traction batteries are the favourites for light commercial vehicles, golf cars, surface boats, material handling vehicles such as forklifts, airport ground support equipment GSE, e-bikes and mobility vehicles for the disabled. Various benefits Actually, these vehicles do not form a coherent group when it comes to their needs for traction energy storage.

DIY DC Motor Controller. Paul Holmes built his own DC motor controller, saving himself a lot of money on his EV conversion. This is how he did it. It really seems simple enough that I think I could do it, so that's saying something; ) This is part 3 of my interview with Paul Holmes.

The first section is how he built an electric car for about 2200 dollars... ...the second section is his electric vehicle parts list. How Paul Got Started on This Lynne: Paul, not a lot of people tackle the job of building their own DC motor controller. Paul: I saw a really simple dc motor controller schematic for controlling a little fan. He suggested that I use a microcontroller instead of the 555 timer. Then... I took a break from it while converting the car over the summer. Christmas break came along, and I got bored. I had read about a 144v 600amp dc motor controller that Ian Hooper had made. He didn't have a control section schematic, so I went to work on that. You Can Do it Too! It's definitely something that anyone could do, then.
