Default Hydra and an In-Car PC or Carputer?

I've been thinking that a carputer with a touchscreen interface hooked up to a hydra would be a really cool setup.
I have been doing some research on www.mp3car.com and there are some cool options including a touchscreen that has a bolt in kit for the WRX double-din http://www.mp3car.com/store/product_...roducts_id=143

Has anyone done anything like this?
Any considerations for the motherboard and computing power I might need? I can't imagine the Hydra necessitating much besides Windows.


I will continue to update on my progress.
I think I will scrap a CD player and go with a 100GB hard drive full of MP3s. I plan on having bluetooth for my phone and possibly WiFi and GPS. We'll see.
Cheers,
Eric

I thought about scrapping my double-din kenwood lcd to do this, but I realized that the touchscreen for the pc, while cool, isn't that necessary. I still have touch-screen stereo and nav controls, so I botched the idea.

You may want to look through the Car Audio section as we cover Carputers in there. I have some links in my HU FAQ that can be found from the manfiesto sticky'd at the top of the Car Audio section.

I've been wanting to do this for the last 2 years, but can't bring myself to spend the money on it, especially when the Hydra has no configurable dashboard type screen.

Plus I realized that a 7" screen will not cut it for reasonable tuning, IMO. I have a hard enough time staring at 1024x768 on 14" as it is.

Thanks for the advice on the Hydra dashboard screen situation. 7" will be small...but a nice feature will be the ability to change maps through the touchscreen.

tuning may be too small, but you can use it for a gauge too.

--I have been researching the possibilities of installing a windows based touchscreen PC into automobiles for a few years and have acumulated alot of valuble information. Im in my final stages of devolpment on a complete system that will include MP3/DVD/Media storage,am/fm/satilite radio/tv,GPS W/touchscreen capable mapping sofware,WiFi,bluetooth & engine manegment capabilitiys as well as suitable amp pre outs for high quality audio componants

Get a mini mac, for $600 you have a fully built unit, and you can now run windows with it just like a PC. there are a few good mounting point like the clock area (guessing there is room as people have install din size headunit there), in the glove box, take out the ashtray and install it there, arm rest area, and many other places. I was going to do it, but the 7inch is just too small to tune, and I don't want to tune from the back sit with a flipdown. So I will just get another laptop to tune with, if I get the clutch worked out.

That's a cool idea. I definitely want the touchscreen aspect for MP3s and Bluetooth phone stuff.

I did it
I had a lilliput 8" touchscreen and a miniITX carputer that I built.
It was fun and easy to tune and drive at the same time. The only problem I ran into was voltage. If car voltage dropped below 12.3volts, my hdd wouldn't spin and then.... crapolla. To fix that I went to a laptop drive. They run on the 5V bus and all was good. The other option you have is to put a )small 12V battery (from a security system or emergency light) and a diode in parallel with the power supply. Both are available from Radio Shack. The price is about 50 bucks when it's all said and done. This keeps supply voltage to the carputer at 12 volts when car voltage drops.

Trust me, this is an issue if you don't take care of it. You do a lot of tuning with the engine off and the key on. It was the bane of my existance for a long time.

The coolest part about this whole setup was the ability to run media engine. I could watch movies, porn, pictures, play mp3's etc right through my car stereo. It rocked. Visualizations are cool when you are driving too.

As mentioned by ImprezaRSX voltage is a major concern. I have tuned cars that have had PC/Car computers in them and they draw so much current it affects the voltage system on the car and the ECM. You must remember the ECM, the fuel injectors and the coil packs must take priority in regards to voltage.

Also have the PC bootup with a push button and not automatically with the ignition as it could be difficult to start the car especially when cold.

As mentioned a dedicated battery would be a good choice. Also the newer Subarus have better alternators it appears as they hold higher voltage. This is true, on automatics at least, as my LGT would hold about 14.2 volts no matter what and my WRX was lucky to have 13.3 volts.

Thanks,
Phil

I've been running a carPC from mp3car.com for 4 years now (Via 800 Mhz processor), no issues running a full windows XP install, EcuTek DeltaDash, UTI for the UTEC and itunes. Make sure you get the power supply module, it's designed for car use.

If the CarPC is pulling that much current you have a short. The power supply module is rated at 90mW, tiny. No voltage drop.

This was the same setup that I put togther for Jeff Perrin for his old H6 powered STi. Jeff used his setup with the Hydra, so it does work.

Just another opinion for this thread.
