Here’s an outstanding surface mount soldering guide from curious inventor -
Surface Mount components, as the name suggests, attach to the surface of boards, not through holes like older components. SMDs (“Surface Mount Devices”) are lighter, cheaper, smaller and can be placed closer together. These factors, among others, mean that the days are numbered for through-hole components with widely spaced leads.
This set of guides will demonstrate (relatively) inexpensive tools and methods for soldering and desoldering SMDs. The first page, Surface Mount Soldering 101, contains a 9 min. video overview. The pages that follow contain more pictures and go into more detail. They also cover some topics not in the video, like hand soldering a QFN chip and using solder paste with a toaster oven.

I recently came across a 4-volume set of the Popular Mechanics Illustrated Home Handyman Encyclopedia & Guide (from 1961) in the bargain bin at a local used book store. Of course, I grabbed them.
The ~4000 pages of projects are amazing – it’s basically your grandparents’ equivalent of MAKE Magazine. Tons of the projects wouldn’t even be printed today due to liability concerns.
Everything from planning/building/remodeling a house, woodworking, metalworking, making your own boat/go-cart/children’s playground equipment, indoor shooting ranges, to gardening, farming, and equipment to make handling your animals easier.
Over the past four days I’ve taken pictures of the title pages and illustrations for the most interesting articles, and put them up on Flickr. I’ve also contacted Popular Mechanics to see about getting permission to break out the scanner and make proper PDFs of the best projects.

There are over 300 images from the pages of the encyclopedias, great stuff.

Here is a snowmobile cutter I built over the last winter. It is a cat chasing a mouse chasing a chunk of cheese. The cheese is the hitch and the cat is the actual trailer. It is sized to carry a banana box and a bit more. The cat’s tail is a handle to open the storage area and is held closed with magnetic latches.
As I haven’t made anything with foam and fiberglass in some time I wanted a project with many compound curves.
People ask if it will carry passengers. I briefly considered a rumble seat but despite our well maintained roads it seems passengers deserve a suspension. Someone without a snowmobile might consider a smaller dog or person pulled version or toboggan.

This device “shreds” plastic bottles to make them easier to carry and to make crafts with them -
Aiming to reduce the volume of PET bottles carried by “catadores” (people who collect bottles and other kinds of waste from streets), Takashi Utsumi developed a device with which one can rapidly shred PET bottles into ribbons suitable for use in crafts. There are two types of PET shredder:
