To build one entirely from scratch you will probably need several thousand dollars worth of assorted digital logic integrated circuits and just the CPU will be about the size of a two drawer file cabinet. Another easier possibility is to use one or more Field Programmable Logic Array integrated circuits, the hardware costs would be less than $1000 but costs for the development tools could be prohibitive (unless you can get permission from a company or university that already has licences for the development tools needed by the Field Programmable Logic Array you selected).
Don't bother trying unless there is some very special need for a unique type of computer, just buy an off the shelf microprocessor.

You need a design for a helicopter. That design will tell you what materials you need...because every heli has different materials in it. The things you need to build a Robinson R-22 are different from the things you need to build a Sikorsky CH-53E.

You need 10 soft clay.
To build a house, you will need materials such as wood, concrete, steel, and bricks. You will also need resources like tools, equipment, labor, and a blueprint or design plan.
get steel or brick
You need an architectural plan, a building permit, and building materials.
I want to build a conservatory on the outside of my house. Which building materials would I need to buy in order to do this?
you need wood, space, and money

you will need a cpu fan,a 9 volt battery and a clip, rubber bands and four pens
First design the windmill then make a list of the materials required to build it. Obtain the materials and put them together according to the plan.
