Luka EV

Build a road legal electric car powered by hub motors

Project aims.
Top speed. 130km/h
Weight. Under 750kg
Range. Over 300km on a singe battery charge
Retail price. Under EUR20,000
Project time frame. Must be Certified to drive on EU roads by Sept 1st 2015.
Appearance. Must be a beautiful vehicle .

Is it possible to build a production electric passenger car in under a year.?

Here are the key ingredients.

Design Bodywork>

Too expensive to hire Pininfarina. That would cost millions... So, we will take a pretty car from the world of gaming, with full files in .3DS & try to convert the file to Solid works....3ds designs usually cost about USD100 to buy.

Design Chassis. >

There is plenty of information about street legal chassis available. Lets take the basic info & design chassis to fit the body.

Keep it Simple >

It has to be all electric & let add a twist & use in wheel hub motors.. This means we do not need many complex parts & we can keep the weight low & reduce complexity.

Keep it Light >

Weight is critical !. Power requires has a direct relationship to weight. Less weight = less power required = less batteries & smaller motors = LESS WEIGHT. A virtuous circle.

Deign for mass production >

If any process can not be done in mass production, do not do it in the prototype.

Stick by the project aims >

No deviation from the stated project aims.

How to Make a Clamp for Miter Joints - Ron Hazelton Online - DIY Ideas & Projects

Here's some good Woodworking Tips. Check out the links below for more info...


How to Make a Clamp for Miter Joints

Go there to see video and read the article...

Shop-Made Miter Clamps

I try to be as self-sufficient as possible, so I like to manufacture my own tools whenever I can. I designed miter clamps that are simple to fabricate and require only scrap plywood and readily available hardware.

For one clamp, you need a hardwood plywood scrap, a piece of 3/4" aluminum T-track, a 1/4" T-bolt, a star knob, a fender washer and a few screws. High-friction grip pads are optional. I suggest you use good quality 18mm (about 3/4") thick Baltic birch plywood. This material is strong, smooth, and stable. It has very few voids and a nice, plain grain.

Some MP4 Videos are Crashing Firefox 37 in Fedoa Linux

This Video - Apollo 13 "Houston, We've Got A Problem" NASA Free Download and Streaming Internet Archive (".Mp4" version) Crashes Firefox 37 in Fedora 14. But, the ".Ogg" version plays, just fine. Firefox in Fedora 14, has been crashing allot, for a couple of weeks, on many videos. Not just this file or on I tried starting Firefox in Safe Mode. Which disables, all Addons. But, that was no help. I tried turning off some Plugins. VLC and Open H264 (No Help). And I turned off both Flash Players that I have (No help). Not that MP4 Videos are Flash Files. But, some Online Video Players, use Flash to make them work. What ever the Video File Type. And I know, that, uses both Flash and HTML 5 Players. You can switch between them. But, I have been sticking with the Flash Player. Because I have had trouble with their HTML 5 Video Player, not working. On my own Music and Video Files, that I have on (Christian Music Underground (CMU). Reminder - I should try switching to HTML5 on this video in Fedora 14. I have both Adobe Flash Player. And an Open Source Flash Player, called Lightspark. On my Fedora 14 and Fedora 20 Systems. I use the Fedora 14 system allot. Because, it has all of the Apps, that I spend years finding, installing and so on... I just uninstalled the old Gnash Flash - SWF file Player. To see if that helps (No help). I'll try playing this video, in newer versions of Fedora 20 (works perfectly) and 21. See if it crashes them too. I could try "The Refresh Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Consider using it before going through a lengthy troubleshooting process." But, this will Delete all of my Firefox Addons. I did Back them up with the Export App, Addon. But, I hate to go through all of that,and have to reinstall all of my Addons. If I don't have to... I have Hardware Acceleration, turned of in Firefox in my Fedora 14 System. So, that's not a problem. See the reference links, below, for more info...

All work and no play makes Jack a dull boy. I couldn't agree more with this wonderful proverb. The first game made on a computer, titled "Tennis for Two", was way back in 1947 and later, in 1962, came the first popular digital game named "Spacewar!". Thereafter, man has been trying to expand the capabilities of gaming on a personal computer. Computer games and gaming engines have come a long way since then.

Passion for developing games had reached another level, and developers started giving out their work for free to people.

I've been asked numerous times whether freeware games are worth it and whether they give the same amount of enjoyment as other big name commercial games. The answer I give them is yes. In fact, I've had the most fun playing freeware games in this list.


The Original Video Game

Bounce over to the history of Tennis for Two, at The Dot Eaters: Video Game History 101

Designed by William Higginbotham in 1958 at Brookhaven National Labs on Long Island, NY, Tennis for Two is commonly regarded as the first video game ever designed. This video features a reproduced version of the game built at Brookhaven using original components, for its 25th anniversary.

First video game

From Wikipedia, the free encyclopedia

There are numerous debates over which game should be considered the first video game, with the answer depending largely on how video games are defined. The evolution of video games represents a tangled web of several different industries, including scientific, computer, arcade, and consumer electronics.

The "video" in "video game" traditionally refers to a raster display device.[1] With the popular catch phrase use of the term "video game", the term later came to imply all display types, formats, and platforms.

Historians have also sought to bypass the issue by instead using the more specific "digital games" descriptive.[2] This term leaves out the earlier analog-based computer games.



The history of video games is filled with events and earlier technology that paved the way for the advent of video games. It also includes games that represent direct steps in the evolution of computerized gaming, and lastly the development and release of video games themselves.

Cathode Ray Tube Amusement Device (1947)

Circuitry schematic of the Cathode Ray Tube Amusement Device, patented in 1948.

The earliest known interactive electronic game was by Thomas T. Goldsmith Jr. and Estle Ray Mann on a cathode ray tube.[3] The patent was filed on January 25, 1947 and issued on December 14, 1948.[3] The game was a missile simulator inspired by radar displays from World War II. It used analog circuitry, not digital, to control the CRT beam and position a dot on the screen. Screen overlays were used for targets since graphics could not be drawn at the time.[1]

Chess (1947–1958)

Alan Turing, a British mathematician, developed a theoretical computer chess program as an example of machine intelligence. In 1947, Turing wrote the theory for a program to play chess. His colleague Dietrich Prinz[4] later wrote the first limited program of chess for Manchester University's Ferranti Mark I.[5] The program was only capable of computing "mate-in-two" problems and was not powerful enough to play a full game.[6] Input and output were offline, there was no "video" involved.

Bryer Bettencourt (1950)

Main article: Bertie the Brain

A specially-built machine for playing Tic-Tac-Toe, Bertie the Brain was created over the summer of 1950 by Dr. Josef Kates. Showcasing artificial intelligence with customizable difficulty levels, it was put on display by Rogers Majestic at the 1950 Canadian National Exhibition.[7] Moves were entered on a keypad and displayed overhead.

Nim (1951)

A drawing of the NIMROD computer.

On May 5, 1951, the NIMROD computer, created by Ferranti, was presented at the Festival of Britain. Using a panel of lights for its display, it was designed exclusively to play the game of Nim; this was the first instance of a digital computer designed specifically to play a game.[8] This machine was based on an original design built by E.U. Condon in 1941, after having acquired a patent in 1940. The machine weighed over a ton, and a duplicate was displayed at the New York World's Fair.[9] NIMROD could play either the traditional or "reverse" form of the game.

Strachey's Draughts Program (1951)

Main article: Christopher Strachey

Christopher Strachey developed a simulation of the game draughts for the Pilot ACE that ran for the first time on 30 July 1951 at NPL.

OXO / Noughts and Crosses (1952)

Main article: OXO

In 1952, Alexander S. Douglas made the first computer game to use an electronic graphical display. OXO, also known as Noughts and Crosses, is a version of tic-tac-toe for the EDSAC computer at the University of Cambridge. It was designed for the world's first stored-program computer, and used a rotary telephone controller for game control.[10] There is a description of another "fun" program for EDSAC.[11]

Tennis for Two (1958)

In 1958, William Higinbotham made an interactive computer game named Tennis for Two for the Brookhaven National Laboratory's annual visitor's day. This display, funded by the U.S. Department of Energy, was meant to promote atomic power, and used an analog computer and the vector display system of an oscilloscope.[12][13]

Mouse in the Maze, Tic-Tac-Toe (1959)

In 1957–1961, a collection of interactive graphical programs were created on the TX-0 experimental computer at MIT. These included Mouse in the Maze[14] and Tic-Tac-Toe.[15] Mouse in the Maze allowed users to use a light pen to place maze walls, dots that represented bits of cheese, and (in some versions) glasses of martini. A virtual mouse represented by a dot was then released and would traverse the maze to find the objects. Tic-Tac-Toe used the light pen as well to play a simple game of noughts and crosses against the computer.[15]

Spacewar! (1962)

In 1962, MIT students Martin Graetz, Steve Russell, and Wayne Wiitanen created the game Spacewar! on a DEC PDP-1 mini-computer which also used a vector display system.[1][13] The game, generally considered the first shooter game,[citation needed] spread to several of the early mini-computer installations, and reportedly was used as a smoke test by DEC technicians on new PDP-1 systems before shipping, since it was the only available program that exercised every aspect of the hardware.[16] Russell has been quoted as saying that the aspect of the game that he was most pleased with was the number of other programmers it inspired to write their own games.[17]

The Magnavox Odyssey released in 1972

Brown Box/Odyssey (1966)

In 1966, Ralph Baer resumed work on an initial idea he had in 1951 to make an interactive game on a television set. In May 1967, Baer and an associate created the first game to use a raster-scan video display, or television set, directly displayed via modification of a video signal; it was also the first video gaming device to be displayed in a television commercial.[18] The "Brown Box", the last prototype of seven, was released in May 1972 by Magnavox under the name Odyssey. It was the first home video game console.[1]

Baer was involved in court battles over patents that spanned the 1970s and 1980s. These trials defined a video game as an apparatus that displays games by manipulating the video display signal of the raster equipment, such as a television set. Games prior to Odyssey did not use a video display, so did not qualify as such in the courts.[1]

Galaxy Game (1971)

In 1971, Bill Pitts and Hugh Tuck developed the first coin-operated computer game, Galaxy Game, at Stanford University using a DEC PDP-11/20 computer with vector displays; only one unit was ever built (although it was later adapted to run up to eight games at once).[19]

Computer Space (1971)

Two months after Galaxy Game's installation, Computer Space by Nolan Bushnell and Ted Dabney was released, which was the first coin-operated video game to be commercially sold (and the first widely available video game of any kind). Both games were variations on the vector display 1962 Spacewar!

Pong (1972)

Pong, also by Bushnell and Dabney, used the same television set design as Computer Space, and was not released until 1972 – a year after Computer Space. It was the first successful arcade video game and led to the popularization of the medium.
