Photos, commentary, and plans for a Star Wars playset (unauthorized) first described in a 1978 issue of Woman's Day magazine.
This is a website that automates creating a personal handwriting font. When I did this twelve years ago, hand tracing letters with Adobe Illustrator, then importing them into Fontographer, it took me months of spare time. Now it is an online app, available for free.
Segway (ginger/it) clone built for about $2000 using off the shelf parts.

Simple railguns, radios, PVC vacuum pumps, etc.
A standard computer keyboard reworked with typewriter keys and a brass frame to make a very old fashioned looking interface.
Plans to build one of the first electronic music instruments using just parts from Radio Shack. The creator warns these are not for the inexperienced, and soldering is required.
The Icyball was a commercially sold refridgeration system that had no moving parts and was powered by a heat source. Perfect for on the road cooling, or backwater farms with no electricity. This page discusses a home built modern version.
A simple to make and historically very popular ink, now the bane of archivists due to its strong corrosive acidity. This site is primarily aimed at archivist, but has this side bar on modern translations of traditional iron gall recipes.
This hobbiest has recreated a mechanical television (a moving light is rapidly turned on and off by radio signal to create an image), put a pair of eye holes in for stereoscopic images, added spinning RGB filters to add color, and built a mechanical camera too.
This site is one of the more out there catalogs of fun things to do with microwave ovens. Sites like this help establish the microwave as the single most exciting appliance in a typical house.
Several college playing-with-fire "experiments" with details on how to recreate them. Four of the five are merely good, but number three, "The Act of God" is standout.
You might want to hold back on doing this one if you want your security deposit back when you move.
Plans for a mylar kite with with a surface area of about one and a half square inches (on each side). Perfect for a kite to fly in the breeze of your computer power-supply fan. (I used mylar from potato chip bag for mine.)
The Pot-in-Pot is a very low tech, no electricity, no compressor, refrigerator. As the name implies it is made from two pots, one inside the other, and the gap filled with wet sand. The evaporation of water from the middle layer is the source of the cooling. Invented by Mohammed Bah Abba of Nigeria.
Complete instructions to make a small rocket fueled by a single paper match.
This is a camping stove made from aluminum cans and epoxy. The basic design works with most any soda or beer cans, but the specifics here are geared towards a 12oz Pepsi can and a 14.9oz Guinness can.
Some photographs and several different pinhole camera designs, ranging from 110 based mini-camera that can take pictures from inside a mouth, to "wheely bin" garbage can cameras that use 1.4m x 1m paper.
Cheap phone cords have many non-telephone uses, apparently.

Gallery of MacQuariums and links to various Mac-based aquarium sites and plans.
Various computer aquariums, including old Macs and even Apple Lisas.
A Mac Cube transformed into an aquarium.
A "foundry in every kitchen". Special crucible construction techniques to make microwave smelting and casting workable. An all in one crucible and mold is made, the metal is melted in a very slightly modified (masking tape over vent holes) microwave, about 17 minutes for a third of a kilo of silver, then the crucible/mold is inverted to make the casting. Clever and appealing.
Antique scientific instruments like astrolabes, compasses, sundials, and armillary spheres reproduced, mostly in copper, brass, and bronze.
A personal account of making a home foundary, starting with fashioning a crucible from a five gallon stock pot and ending with some castings. Very cool, but a couple of the steps don't provide enough detail, unfortunately.
Print, cut, fold. Monsters, robots, etc, all from an 8.5"x11" page.
Lots of cool goth/Halloweenish paper projects to print and assemble. Files are MS Word documents, rather than PDFs or plain images however.
Modular origami of a sort. Twenty bills folded in two groups to make a wallet for holding more money. With instructions in a wordless form eerily reminescent of Ikea assembly manuals.
This book for "aspiring paper engineers" provides an encyclopedia of pop-up effects each with explanation of how it works. The more complicated effects which benefit from a model that can be disassembled are not glued shut allowing the reader to open them up to reveal the inner workings. The opening page has a very dramatic monster which serves to illustrate many of the techniques combined for a single creation. The ending page gives an overview of the steps to publish a pop-up book.
I've found this helpful in designing pop-up cards, which I make as one-offs.
Seller of paper automata to assemble and premade cards. Mostly risque.
