Projects of the month
Posted: Tue May 16, 2006 5:33 pm
Ok so I'm undertaking two projects at home.
Project 1: MythTV PVR
What is it: Tivo move over cause MythTV is going to replace you! Ok not really, however Tivo does have limited uses while a computer running PVR software can do so much more. What do I mean. Well check out MythTV.org but, it can do the full functionality of a Tivo, in other words, pause, record, replay live tv. It also goes beyond to allow you to play simulators on your TV, store your entire mp3 collection, hold your pictures, ripped DVDs and then some. In other words its a complete multimedia solution, the kind the MS/Bill Gates has been trying to make for a while. The draw back of course is that you need to build it.
So to build it I went out and purchased some parts. Started with a small form factor case, a Haupauge 350 PVR card, 1256Gb of ram, 2.4 Ghz PIV CPU I had around the house, 2x400Gb HD (total of 800Gb for those who can't add) and of course a DVD/CD Burner. The video card is an nVidia 5500 Dual video + svideo card. The system will also be getting a wireless combined keyboard/touch pad, it will be able to use my wireless joystick and maybe some USB console style gamepads once the system is up and running.
I just installed Linux, Fedora Core 5. Next I will have to install Myth TV and all the things that go along with it like the addons for the games, music, pictures, TVGuide, remote controll software, etc... Then I will be able to do it all in my livingroom. Down the line I will probably get a 2nd Hauppauge card so I can record 2 or 3 shows at a time. Now all I need is a nice big TV and I could be all set....
Project 2: GPS for the Car
GPS prices have been coming down a lot but a decent map enabled GPS still starts at close to $500 or more. Now it is hard to beat that price, especially considering that if you get a TomTom top of the line series GPS machine it has a 20gb drive in it so it can do directions, music and pictures, which is a good deal. About the only thing that could beat that is an actual computer. And as it happens, I just happen to have a PIII 450ghz Laptop available with its screen busted and one with the screen in tact. I have two options. I can build a fully integrated system where the 'PC' is mounted in the trunk and you mount a small LCD up front or you just mount a laptop up front in the passenger area and do some cabling for the GPS.
Ok so to start out, I purchased a US Globalsat BU353 USB GPS receiver ($65). It is one of the waterproof GPS systems that Globalsat sells and as it hapens, it is magnatic so it is easy to install into your car. You can either install it on your trunk like I probably will or do it on your roof. BestBuy and co can install an antenna like that for you for less then $100 if you aren't comfortable doing it. This plugs into the USB port on the laptop. Now all you need is some software and viola, you technically have a GPS solution. The software can run you some money, but it depends on what you get. You can get MS Streets for relatively cheap, but there are actually better products. One such product is ALK's CoPilot, which looks and functions very much like a Tomtom or other built in GPS units. It does support voice control and can run very nicely on touch screen LCD's or tablet PCs. One drawback is that CoPilot goes for $299, which is kind of expensive for personal use. It does work on some phones and can even connect back to ALK so that you have trackable cars, which means that if you have a nice Palm or PocketPC phone with Bluetooth and a data plan, you can get yourself a bluetooth enabled gps unit and CoPilot and you have a $300 GPS device that your family can track. Its actually a great solution for companies that want to track the location of employees/trucks through the web.
Anyway, once you have the laptop and the GPS device and mapping software, you are set to go. Install Windows, install the GPS and the software, mount your laptop somewhere or just put it on the seat next to you (not very safe but it works). Then you want to run some power to the laptop. You can order car chargers that you can either just plug into your cigarett lighter or actually run to your battery. Run an audio out cable to your stareo. If you have a Tape deck still, it allows you to go the cheap route and just put one of those old stule tape cd audio solutions in, if not then you have to run a cable to the back of your head unit. Alternatively, you can purchase a 7" touch screen for around $200 and just mount that. Run a serial and Video cable to the laptop or PC that you mount in your trunk. The GPS unit can be mounted on your trunk, which is an easy install, and all that is left is an audio cable into your stereo and you are good to go. If you have the money, you could even purchase a PCMCIA cell card and buy a $60/mo data internet plan from just about any cell provider and you have a 128kb/s internet connection anywhere in the US. As an example, Verizon sells their card for $50 and $59/mo for the data plan w/2 year agreement. Verizon actually claims almost DSL speeds, which would be fairly fast browsing. US Cellular's card is more expensive and their service isn't nearly as fast, but then again I've seen their service but I haven't seen Verizon's so I can't verify Verizon's speeds.
Anyway, the only real thing to worry about at this point is power. There is actually a decent solution for power. Use a UPS. Buy a small 350VA UPS for $50. Disable the stupid audible alarm and wire that into your car's battery. Then just hook the Serial or USB cable to your PC and set it up so that 5-10 minutes after power loss, you want the PC to go to sleep. Finally, just get a wireless keyboard that you can use to enter addresses quickly or of course to use with the PC when not driving and you have a fully computerized car. As a last resort to protect your battery, you can put in an inline switch that will kill your PC access to the battery when the voltage drops to 11 or 10 volts. this will allow your car to still start without any problem even if for some reason your computer tries to pull too much power from it.
So any ideas or recommendations? I'm not sure how far I'll get with the car project, but I'll try to post pictures of both as I go along.
