Review: Estes Proto X nano quadcopter

Jonathan Fincher

You may have noticed that we enjoy our quadcopters here at Gizmag, from the GPS-equipped Phantom 2 Vision to the palm-sized 1SQ V-cam. Recently though, we had a chance to try out a somewhat unusual style of quad in the form of the tiny Proto X from Estes. It may not have a laundry list of features under its belt, but the Proto X does hold the distinction of being the smallest quadcopter we've ever reviewed ... by a huge margin.

Façam esta Engenhoca, é do mais fácil, e poupa-vos horas de trabalho.
Básicamente, é um Fio aquecido por Corrente Eléctrica, que aquece o Acrílico ao longo duma linha, que amolece e permite dobrar as Placas de Acrílico, duma forma exacta e limpa.

Acrylic Bender

This weekend I decided to make an acrylic bender. I got the idea from a video on the internet.


I bought a cheap hairdryer ($18) and removed the filament. I made the following measurements with a multimeter across the mains lead:

0 1 2
 0 inf115 95.5
 Heater 1 inf 70.6 52.3
 2 inf 61.6 42.9

All in all, I was impressed by the design of the hairdryer. The heater seemed to run in series with the motor, there was what looked like a bi-metallic thermostat that would cut out if the outlet was blocked, and there was a non-resettable thermal fuse as a last resort. It seems like that it would be quite difficult to start a fire or do damage with this.
The construction consisted of having the heater elements inside U-channel aluminium. To either side I screwed a wooden board to make a flat work surface.
I cut a piece of aluminium U-channel to length, then used hot-glue and scraps of wood to seal the ends up. Mixing some plaster (50g plaster, 35g water) and pouring it into the trough made a nice heat resistant, electrically insulating base to run the wires on.

DIWire desktop machine bends wire into 3D sculptures

Jonathan Fincher

Over a year ago, Pensa Labs caught our attention with its impressive DIWire Bender, a small machine that bends thick wires into elaborate 3D shapes by following simple vector drawings. Since then, the company has been refining the wooden prototype we saw before into a sleek fabrication device that's fit for consumers. The result is a more compact, easier-to-use DIWire that can turn pieces of wire into creative 3D sculptures while sitting comfortably on a desktop.
