Man Builds 7-foot Grandfather Clock from Lego

Ravalox writes "Eric Harshbarger has built a 7-foot-tall grandfather clock exclusively from Lego. It keeps accurate time and needs no electricity; it needs to be weight reset every 13 hours. Other pictures include the gears, numbers, the face, and the pendulum mechanics."

Kit

I'd love to know when the kit for this goes on sale. Of all the large-scale Lego designs I've seen, just once I'd like someone to start selling a kit or at least instructions to built it yourself.

Re:server made of lego too?

Just finishing up my end of semester projects, had to analyze several CPUs I designed this semester. One very simple one used 1048 logic cells, but could do integer arithmetic, jumps, branches, and memory operations. Not quite sure how many transistors that translates too, but normally an FPGA cell is a binary operation. Removing several of the odd arithmetic operations would lower that size quite a bit more. I also designed a 5 stage pipelined CPU with 32 word instruction cache, and 32 word data cache in about 2300 logic cells.

When the first vacuum tube based computers were invented, I'll built the designers felt like they were implementing a CPU of this size in Legos. It seems funny now, but this analogy probably holds a lot of water.
