Um revólver excêntrico, três canos e 16 tiros, com a possiblidade de disparar os 3 canos por tiro!

The triple barrel, 18-shot Pistola con Caricato revolver

By Brian Dodson

A host of unusual firearms have been floated and (mostly) abandoned over the two centuries of largely trial-and-error design. After our recent coverage of Arsenal Firearm's AF2011-a1 double barrel semiautomatic pistol, we wondered if more extreme versions of multi-barrel repeating handguns existed. The outlandish Pistola con Caricato three-barreled revolver is a definite candidate.
This revolver was manufactured in Italy during the early part of the 20th century, complete with three barrels and 18 chambers in 6.35 x 16 mm semi-rimmed caliber (.25 ACP). While rather more bulky than one would want in a pocket handgun, 18 shots would provide a certain feeling of security in back alleys and dark lanes.

Para chamar a atenção de Alunos e quem mais queiram, uma Bateria de Condensadores, a partir de Cãmaras Fotográficas de deitar fora:

Make a cheap disposable camera capacitor bank

This instructable will show you have to make a simple capacitor bank and charger out of old disposable cameras that you can get for free at your local store.

You can then use it for powering things such as coil guns or just blowing things up! See the second picture above? that was the spark created when I discharged such a capacitor bank. It was also very loud too!

O Contraptor vem-vos dar a possibilidade de criarem os vossos projectos, como um Meccano para CNC:
