We were on TV!

Today our car was shown on national television - channel 2 on their Saturday night news broadcast.

It was short and fun! You can download the entire movie clip (2:30 minutes) from eMule. Some pictures from the clip...

We assemble all the parts for a run:

Zvika is explaining to the reporter about the project. Short transcript:

Reporter: But it's complicated to build such a thing, no?
Zvika: Not that complicated. You just need to really want to do it.
Reporter: Now please explain - why do you really want to it?
Zvika: Good question :-)

The reporter, Yuval Dror -- thanks man, for a great report!

We'll be on TV

well... at this point we're on a video tape of TV crew...
It should air this Saturday May 21st at 20:00 israel time.

Channel 2 news came to visit us (the power of the BLOG) for 3 hours at the workshop
to see how we setup the RVC, drive it and try to explain why the hell are doing this.
I think that they answered themselves when each of the crew members had to take it for a ride before he left (see the pic)

Desgin draft for new Gauges Panel Faceplate

We plan to modify the panel faceplate to support some usefull information for the RVC
for example - Current Gear - see draft


here it is inside the panel:


If you have any ideas about other interesting info to put in - please write a comment

Original guages are back in place

Today I went with Gil, a friend of mine, to install the original guages back in the car. It took us a while to put everything back together, having the lights work and the microcontroller moving the needles. It turns out that most of the light bulbs got burned while we played with them. Also, it took us a while to figure out that our power adaptor did not have enough juice, so we hooked up a computer power supply and used the 12V to get more amperage.



We then put it back in the car...

Getting the original guages to work

After we managed to make the gauges work by "implanting" servo's in them, we decided that it's not good enough, since we would like the original car to remain unmodified as much as possible.

The guages needles move according to the frequency that they receive. Since it is impossible to generate those frequencies from Windows (or any other non real-time OS), we needed to move into hardware (yeah!).

We decided to go with Atmel AVR microcontroller chips (mainly because that's what we could easily find in Israel). We got a sample of an ATMEGA16 and wrote some C code to generate the frequencies (WinAVR and AVRlib). Since this is the first time we used this platform it took us a few hours to get it working.

Generating the frequencies is not enough -- you need the PC to ask the microcontroller to generate the right frequency according to the speed/rpm in the game. Unfortunatelly, the AVR cannot speak directly with an RS-232 interface, so we had to connect a MAX232 chip in order to get it working.

The sequence is as following: there is a process on the PC which collects the games telemtry with Nascar 2003 APIs. It then translate the speed/rpm to commands which are written to the microcontroller via a COM port. The microcontroller parses the requests and set the frequencies to the gauges accordingly.

Nice :-)

Videos available via eMule

As you've noticed many people have accessed this blog, which exceeded the limit to the server on which I publish the videos. Many people have asked to share the videos with eMule/Bittorrent. For now I've published them with eMule and will later on make them available with Bittorrent.

The ED2K link is here - feel free to share.

If you can,post these Videos where you can and write here a comment with a link to the files.

Enjoy,

We’re on major geek sites - Hello World : )

Just came back home, checked the blog and saw something strange – comments…
It seems that somehow somebody found out about our little project here and posted it on diffrent web sites (Slashdot among them - You can read it here )

As veteran geeks we’re extremely FLATTERED!

Wow, we were not expecting that, definitely not on this early stage.
We still have big plans and a lot of work – feel free to come back again and check the progress (usually we work on weekends)

We are building this project for FUN - learning more about cars, electronics and software.

Stage 2 will be all about hydraulics (we hope)

Due to bandwidth limitation - our video hosting site went down – sorry. we are trying to find a diffrent solution so you can get to see the action and hear the sounds.

We’re lucky we had most of the pics on Flickr.

Thanks for commenting , we appriciate your feedback and support.
For the sake of quick swift visitors I’ll reattach some milestone pics.

It's Alive Videos !!!

This is the first time we actually tried to get it working



We decided to have some fun with it



We stubled into a bug in Nascar which froze the whole system for a few seconds. Funny enough it was exactly when a Viagra car passed us :-)



This is how looks inside and outside

Running out of patience we kinda made some shortcuts "just to see it working... "
AKA "After a week of hard work, why don't we play instead of keep fighting against metal, plastic and electronics"

OK, so we had to finish the steering. Lot's of small annoying metal parts that need to work together smoothly. Finally the streeing part was attached properly but it needed to be raised somehow. So - yes the electronics are in a bucket : )





Then we put some white (dirty?) cloth we had around on top of the front "window"

/




The projector was set on top of back seat and a "small" speaker right behind the cloth screen for an "IN YOUR FACE" sound.







Connect the power and.... Here you go -

It's Alive

Was a great day!



Next we need to make the gauges work in the car...

Got the Gauges electronics to work, OH Yes!

After a week of trying (while going to work, eating & sleeping in between)
and after searching the web without finding the spec of how to get it to work
and after spending too much time on PWM
it turns out the Gauge needed a 12V + - and a regular 5V PULSE - and it worked!
I generated the pulse from a step motor controller I had - now we will need to generate it from a PC - I hope we can make it fast enough without additional hardware
The nice thing about it this way is that the Distance Meter Works too, how cool.

The SPEED & Distance gauge work - check out the video here
