How To: Building A Light Table Under $80. As a designer, Stefan Fahrngruber of SFA understands how nice it is to have a light table.

How To: Building A Light Table Under $80

I can attest to how nice they are when picking out tiny vinyl cut shapes after plotting. Unfortunately, light tables can be hard to come by inexpensively, and difficult to make. Sure, you can put a light under a glass table, but it doesn’t always work well, the light isn’t distributed evenly, and can still be expensive if you don’t already own a glass table.

Stefan designed a light table that you can make for under $80 using standard decorative LED strips. The idea is to arrange them in a small grid which gives off even lighting while also keeping the construction of the table lightweight. The table is made with an A3 tempered glass cutting mat, size 16.5″ x 11.7″. -LED strip approximately 10 feet long. . -5 foot LED strip connection wire (those are special wires with four color coded lines in the right distance, you can also buy ready made ones but they are rather expensive) -Four rubber feet Related.

14 'makers' who are changing the DIY world. Inventors and tinkerers have always been around, but until recently most “makers” toiled away in secluded basements and garages, fashioning their creations from homemade materials.

14 'makers' who are changing the DIY world

All that’s changed now. With new desktop design and manufacturing tools, affordable and accessible building materials, and the power of the Internet to rally funders and get the word out, even the Girl Scout down the street and the retired hobbyist across town can now launch a company and sell products that were once the strict domain of corporate titans and old-school factories. The maker movement may well be the next industrial revolution. If nothing else, it’s leveling the playing field and putting a novel spin on innovation. The following are some of the dreamers and builders who are leading the DIY charge. 1. Open source PCB design tools. HOW TO – Make Printed circuit boards – An illustrated guide (and round up)

Here’s a good tutorial on making your own PCBs (Printed circuit boards).

HOW TO – Make Printed circuit boards – An illustrated guide (and round up)

And below is our round up with the many other methods - Creating Printed Circuit Boards (PCBs) is easy and fun for the whole family! But read the disclaimer — heat and corrosive chemicals are dangerous ;-) After you’ve prototyped and tested your circuit design, creating a PCB will provide a sturdy and reliable backbone for your circuit and will give your project a professional finished quality. Using PCBs can even help reduce the time you spend building circuits, especially if you are producing multiple units, as you only need to follow a parts placement diagram (there’s no longer any need to worry about specific interconnections).As is usually the case, there is more than one way to do it: there are numerous ways to create PCBs.

They range from the time-consumming and difficult to the fully automated and expensive. HOW TO – Make Printed circuit boards – An illustrated guide – Link. Related: PCB etching – Link.

Spools of thread and sewing machines aren’t the typical tools of choice for designers who work primarily with hard surfaces, but nor are Fredrik Färg and Emma Marga Blanche in the business of doing things traditionally.

Wood Layer Armchair by Färg & Blanche

Employing a technique they refer to as wood tailoring, the duo approach wood as they would a fabric, stitching and sewing as they see fit. ‘We wanted to use sewing in the core of the furniture, in the hard material, so we took away the upholstery element’ says Blanche. By sewing directly onto the plywood, Färg & Blanche were able to use sewing and the shell of the wood as a pattern generator and structural element. Blanche admits that while neither of them studied fashion in university, ‘cutwork and the industry’s way of showing things’ has always been a source of inspiration for them. The Wood Layer armchair embodies their technique with its structure generated by layers of stitched plywood. Fargblanche.com.

Wind Power Generators

Where D^2 is the blade diameter in feet squared, and V^3 is the wind velocity cubed in mph -- this is the year round average wind speed -- see wind maps below. So, a 10 ft diameter wind turbine in 12 mph average winds might produce about (0.01328)(10^2)(12^3) = 2300 KWH/year Note that the energy produced is proportional to the cube of wind speed -- having enough average wind speed is everything in wind turbines.
