Tool Review: Dymo Metal Embossing Tapewriter

Tool Review: Dymo Metal Embossing Tapewriter

Embossed aluminum is pretty much the ultimate labeling material. Without wanting to be morbid, there is a reason why military services around the world choose it for personnel identification tags. Secured with mechanical fasteners, instead of adhesives, an embossed aluminum label will stand up for years against water, extremes of heat and cold, prolonged direct sunlight, and any organic solvent you care to throw at it. This is a true “industrial-grade” labeling tool, and if you can snag a used one for a reasonable price, you can expect a lifetime of use from it.

How-To: Fold-Up Fresnel Reflector

How-To: Fold-Up Fresnel Reflector

Uwe Oehler has written a simple program that prints out fold-up paper templates for the conic sections that make up the reflective surface of a Fresnel mirror. Cut the templates out of cardboard, cover the cardboard with aluminum tape, fold up the sections, and apply them to a flat backing. Even the relatively simple, five ring, 59% coverage reflector shown in the video will burn holes in construction paper under modest sunlight.

Sub-0 Cardboard Hexapod Robot

Sub-$100 Cardboard Hexapod Robot

Mike Estee has been laser-cutting hexapod limbs from cardboard and is making great progress on his hexapod project. As he explains:

As I’ve written about in the past, cost can be measured in many ways. For this exercise I’m primarily interested in cost of materials, cost of manufacturing, and assembly time. Design time isn’t particularly optimized here, but as we build on previous iterations, hopefully we can stay ahead of complexity. On the cold hard cash front, I think I’m doing pretty well. This little fellow consists of: $1.00 in cardboard, $54.60 in servos, and $29.95 in servo controllers.
