No, Legos can't compute, but you can build a Lego Computer. I had assorted computer parts but no case for them. I also had a few thousand legos. So I decided to build a computer case from the legos.
Step 1: Lay out all parts of Computer
I inventoried all of my computer parts to make sure I wasn't missing anything important. I had a CD drive, a diskette drive, a motherboard, a hard drive, a power supply and all cables needed to connect them. I also had a mouse, keyboard and monitor.
Step 2: Lay out Lego parts
First, I layed out the parts for the base. I used large flat pieces to build the base and I mapped out approximately where each computer part would fit.
Step 3: Assembly - Step 1
First, I placed the motherboard leaving about an inch around all sides to build the walls of the computer case. Next, I placed the hard drive to the right of and perpendicular to the mother board. To the right of the the hard drive I placed the CD drive, then the diskette drive.
Step 4: Assembly - Step 2
Next, I connected the power supply and the ribbon cables to all of the pieces I had placed.
Step 5: Assembly - Step 4 - Making the Case
I started off by using large rectangular lego pieces to build the walls around the computer parts. I built one row at a time all the way around making sure that CD and diskette drives could open properly. Once I got to the top of building the case, it was time to build over the CD and diskette drive. Since they were different sizes it was difficult to hold them in place. You need to experiment with which is way best for you depending upon the size of the drives you are using.
