I've thought about buying a netbook, like the Asus Eee 1000HE with 2Gs of RAM...but I don't like the 1.6Ghz processor for my application...
If I were to buy a mini-ITX, I have a friend whose a computer wizard, and he could probably put it together for me, assuming I didn't buy a whole mini-ITX system in a housing case. I have two 12V 10Amp hour battery packs just lying around and hopefully I could power the Mini-ITX with those, with the right supply.
Thanks, guys, but it doesn't have to be terribly small. just as long as it's not my 15" laptop widescreen laptop. I also forgot to mention the computer will be running speech recognition. However, I measured my CPU power while running Speech Recognition and it took from 50% to 100% of the CPU! I don't know if the speech recognition engine for Windows XP is any more power efficient. That, along with Roborealm and everything it will be doing, would require a lot of CPU dedication...Here's what I'm looking to put together with my friend, who's in on this project as well.-Intel BOXDQ45EK LGA 775 Intel Q45 Mini ITX Intel Motherboard-Intel Core 2 Duo E8400 Wolfdale 3.0GHz 6MB L2 Cache LGA 775 65W Dual-Core Processor-Kingston HyperX 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory-Western Digital Scorpio Black WD1600BEKT 160GB 7200 RPM 16MB Cache SATA 3.0Gb/s Notebook Hard Drive - OEMI still need to check with my friend if this combination will work. Some worries is price for these components (On newegg.com its a total of $400+) and it might be a little overkill (if not a lot, but I'm not sure). It would certainly be more powerconsuming than 30 Watts. For +65Watts, at 12V thats a little over 5 Amps, corrent? Watts = Voltage * Current? And that's not accounting for the memory and HDD power...Hmmm... Any suggestions? It will be a while before I purchase any of these items, so I'm going to spen a lot of my time planning in the meantime.
So the capacity of a hard drive effects the power consumption, and not (just) the HDD's rpm? Interesting.
