Solar energy is horribly inefficient, it only converts appx 3-4% of the energy available it, it costs a fortune to. i would suggest using a different form of renewable source. use solar energy to heat you water (very simple non-electrical system - black hose-piping within a black box - supprisingly effective for what you may thtink it is, this also saves money on electricity. \n\nYou could convert your central heating to a heat engine system (loads of info online about it) - expensive outlay but unlike solar cells very efficient with it.\n\nother than that common household electrical requirements nowadays are sickening and really need the national grid juice to power it. If you have a river/stream by your house tha can easily be harnessed to power all your lights, refridgerator and basic amenities ... - however how many ppl actually have a stream... LUCKY BAS***D'S!\n\nGood luck with What ever you do, any one cutting down their fuel useage is good!!!

Keep checking online. I did print out plans with sources of material last year.  Also, there are finished frames for sale. Maybe Instructables? There are projects for welding bikes,

Go to http://unitedmicro.com  They have the best site for constructing your own computer that I know of.  When you build a computer yourself you save a bundle, feel good about yourself, know exactly what is in your system and become way more savvy about how to fix it when something goes wrong.  The down side that you will have no "whole computer" guarantee.  These previous answers are right on the mark.  If you want a computer that does what you want it to do you got to do it yourself.\n\nDon't let assembling a computer yourself scare you.  It is pretty much like plugging your periferals in the back of your computer, i.e., if the plug doesn't fit the socket it doesn't go there :)\n\nI built a computer five years ago that was an absolute screamin demon at that time.  The tower and all that was in it cost me about $1,100 (not the monitor).  To buy a simular name brand computer at that time would have cost at least 2,200.  Here I am five years later and the computer I built is still worth nearly what I paid for it.

Start with a multi-cut-out prototype & tape.  Once you've figured the sizes for your parts, disassemble and use a prototype 1-piece pattern with tabs & slots to hold it together.  Work it till it works  :-)

You should build the computer yourself. You can get many parts that you need from garage sales and the like. The parts that I would still buy would be: ATX Case w/power supply (nothing fancy now, just a case w/400 watt power supply), a CPU, a Motherboard, a SATA 250GB-300GB HDD for security reasons, a OEM copy of Windows XP Pro ($140). Unfortunately, CPUs are expensive! You'll have to save your pennies for that!  DVD/CD drives can be found on most recent computers at garage sales. Just ask them if the CD or DVD drives are working. Strip the memory out of the old ones too, it may work in your build. There is usually a sticker on the memory that gives the info on it for that stick. If you put it yours just make sure that it is the right type for the mobo and CPU. This could become a family project, have the kids help you out! They have lots of friends looking to rid themselves of old computers. You can make use of those parts! Go to the library and borrow books on how to build computers. There are a lot of them out there! Shop at Newegg.com on the weekends for parts, they have weekend sales on new parts every weekend. This isn't going to be a $200 computer, but it WILL be what you want! You also can buy parts as you can afford them, and there's no finance charges on cash!

You need copper, and any sized battery. Then you need to do some playing around with it. Or you could just go here and do what they tell you.

If you can get the parts it shouldn't be too hard to put together.  I suggest you try it yourself first as it is fairly straight forward.
