Car Use, what about RF interference?
Car Use, what about RF interference?

New MessageCar Use, what about RF interference? (modified 0 times) Gabo
Just had a thought, I plan on putting this in my car (I already have a gps reciever and some other stuff for it but I've been slacking so I haven't installed it yet). People have brought up the issue of heat, but what about RF interference?? I know it has that sheild and all but just because it claims to comply with FCC regulations doesn't mean it does, my apex ad-600a dvd player claims to be FCC compliant and claims to be region 1 only, however it is region free and macrovision free, and it generates enough interference sometimes to make me question just how compliant it really is. This thing is mainly going to be an mp3 player, it will also do voice navigation (hooked up with my GPS that is) but I can stand some interference when it comes to that, but for mp3s I want it to be as clean a sound as possible. Won't the dc-dc converter and the i-opener be creating enough interference to make it sound a bit crappy, or at least annoying? If anyone has mounted the iopener in their car I want to know if they experienced any of these problems. I have no doubt that any interference can be eliminated with rf filters but this is a topic I hadn't really heard discussed much.

PS Everyone is raggin on the video quality, yeah its bad but ASF movies suck so it would be a good thing to play asf movies. Main reason I'm running 98 is because the good gps navigation software is for winblows, and its a lot easier to get configured than linux, but you do take a big hit in performance. Ohh well, I have another HD I threw slackware on and another one that I'm going to put BeOS 5 on. Another thing I noticed is the amount of money people are spending on these things, with all the upgrades people are doing they could have just bought a good used laptop. I got my i-opener for free from someone who got it durring the beta testing and thought it sucked so they let me have it. I got the hard drives for free from some friends of mine, I'm going to buy a bigger cable (thats the other thing thats holdin me up on putting it in my car) and a winchip 2 200 but thats about it, 32 megs of ram should be plenty for what I'm doing with it, MIGHT go up to 64 but sure as hell not 128. People are just getting so wrapped up in modding the iopener that they aren't keeping tabs on how much they are spending on it. I think its awsome that people are doing this but add up the cost on a winchip 2, 64 megs ram, 2.5" hd, 44 pin cable, gps, touch screen overlay, power supply, etc.. not to mention the iopener and service charges, it just doesn't make sense, the touch screen and 128 megs of ram are just overkill. anyway enough bitching about what other people do.

128meg overkill?

my compiles went down from 30minutes to 15minutes with just the ram upgrade!

many of us will be building software and apps ON this box FOR this box. saving 15minutes * the number of iterations will easily pay for itself. at my hourly rate, it paid for itself the first time I typed 'make'

As far as RF interferance you may want to use large ferrite beads for the (Around)power cord and mouse/keyboard inputs.This may help reducing any RFI.

I dunno, if it isn't going to be used for car use then why not just build a PII machine and buy a flatscreen LCD or go buy a used laptop, sure the iopener is $99 (not including shipping and service charges), but the money you spend to get it up to a real usefull machine just doesn't seem worth it to me, figure in the cost of a decent sized 2.5" hd, 128 megs ram, different cpu, ide cable, cpu cooler, service charges, shipping cost, and what your time is worth. And consider the finished product, a laptop just seems to me like the way to go. Hell I like my iopener and all but if anyone has a decent 100+ mhz pentium laptop witha color display and wants to trade me I won't even think twice about doing it. To me hacking the iopener is something that be low cost (which was the whole attraction to it in the first place, all that good stuff for $99), with enough money you can modify anything, but at what point does it cease to be a hack?

I have a nice notebook already, but the iOpener is SO much more versitle, I am gonna have 128mb in mine as soon as I get some cash (110$), and I already orderd the PowerLeap K6-2 400 chip for it. its gonna make a DAMN nice in car, Nav station (gonna hook it up to my already awesome Garmin GPS3+), Engine monitor (got a friend at GM thats helping me with the serial pinout for the ECU), and MAYBE an MP3 player.. I am just not into MP3's ...

I want it so I can load up driveway detail maps for the GPS nav, possibly a movie or 2 (got a 4.3gb ultrathin (bout 10mm) IBM HD, but am buying a 12gb soon) not to watch the movies, but to listen to them.. some of them area cool to just listen to when you are doing stuff (driving).

I am also looking into getting a touch screen setup on it. I am gonna be running Windows 2000 Pro on it for the "Soft" keyboard feature and also the talking text portion. its also pretty fast compared to 98 in some ways, and a helluva lot more stable.. who wants a BSoD on the free way?! :)

I wonder what would happen if you got pulled over by a local cop and he transmitted on his new high power 800MHZ trunked radio while your i-o is on.....Talk about RFI.......Maybe scramble youre data...

I was on a road trip and had my nice lil IBM Stinkpad on the passenger seat, and my GPS on my dash with an ext ant on the trunk lid. Well crossing into Canada, the security geek at customs was mighy confused (and worried I think).. they stripped my car to the bone soon there after! talk about pissed.. spending 45 min at customs when you are trying to drive 1200 miles in a day isnt cool. so from now on when I am near cops I close the note book,and put something over it :)

I was also driving around a Army base (Ft.Mcoy in western WI (home state)), and was pulled over next to the ammo dump, I made a few mistakes : stopped, pulled out a camera, and was using a GPS to log its position. the guard that almost ran me over in his humvee, was not ammused.. and here we go angain.. strip the car to the bone, and check me for any bad stuff. He made me clear the cam (digital), clear the GPD waypoints and turn it off, and then HE Fdisked the HD. Told me if I had a probelem with it, I go to jail. He then pointed to the big sight basicly saying I cant to any of what I was doing there, and he was in EVERY legal right to bust me down.

so just a warning to anyone thats gonna mount an iOpener in your car... some people in authority dont dig it to much. I think the RF interference is the last concern.

I am currently involved in creating an interface for my car. Here are the details as sent to some friends:
I am starting on my Car Iopener project right now. I got my IO a few
days ago, and decided to replace my control console in my car with the
IO, which ironicly fits perfectly in there. Here are some of the
features that I have planned:

GPS - have the puck locating Linux software to control it.
Linux kernel - Doing this all alone
I am changing the BIOS image to a custom screen - very sleek looking
waiting till Monday when I go into work however, because I will build
the Hdd cable and do some soldering for the audio out there.
I like your plastic screen idea, I am also going to do that at work
I am working on developing a linux X server program to run the console items. It

will report status back on a nice GUI interface. Features include: AC,
heat control, airflow control, CD/MP3/VCD player, and GPS, working on a
LIRC ir control, I swiped an Averkey remote and it has some buttons that I would like to use.


I am curently having problems with the following:
The com port that is for the modem seems to be 4 pins larger than any
other on the motherboard. I removed the modem and am going to see if
putting an ext. com port for the GPS will work. The parallel port is
for the LIRC, so I am kinda sunk here, and as I mentioned, I need a
serial or parallel for the console to contorl so I need to find some
motherboard specks to help me out. (Any ideas???)
Anyway, you are probably skiming this e-mail ryan@msd.com anyway so I will keep it
short.

Bye,
Ryan

USB to Par. and Serial converters could do that.

How are you powering the unit in your car? This is one detail I'm working out on building my (non i-opener) MP3 player for my car.

And that sucks about the guard FDISKing the HD...but you should have been able to use a few utils to get everything up and running again.

I have Earthmate and that sucks, it only works when you don''t need it !! Sometimes cannot track for hrs and then suddenly work again .. I was told this is due to the fact that it's taking location from some satellite and they do this on purpose to confuse those damn missle !!

Wow! The NSA guards are not even that bad at Ft. George Meade, MD! They stopped us from taking any more pix at the big NSA sign by the entrence to NSA HQ, but did not mess with the camera or my laptop running GPS (did not even look at laptop). They did write down ID info on girlfriend and I.

Well.. Put it this way, I was in a restricted area, I went though on open fence that was normally locked with a "Restricted Area..." sign up. and I was 15ft away from ammo bunkers. I am guessing that my bull#### answers of "Ohh, I didnt know I shouldnt be here, ohh, I am sorry I didnt know I couldnt take pics... etc.." I am pretty sure he was just being a prick to me.. But I learned my lesson :)

Hey Procool Joe...Any luck on the pinouts on the serial to ECU for your car? I want to try and get an on screen display of stuff like a tachometer, speedometer, temperature, etc. Any ideas? Anyone with some help? Thank you!
