A Beginner's Guide To Stirling Engines

At the end of the year we had to do a research project on something that interests us. Doing some research on the internet, I came across something called a stirling engine. "So, what the heck is a stirling engine? " You may ask. Well when I first heard of it I thought of a chrome plated V8 internal combustion engine. The next few steps will get more into the history and applications of stirling engines. If history and long boring back stories aren't your thing skip over to the build at Step 4. ( I don't know how to create one of those fancy links so here an old fashioned link. Duct Tape Speakers. Building the Paper Arrow. 12 Impressive Paper Airplanes. CNC Laser Cutter Journey.

Come costruire Google Cardboard e come acquistarlo

LEGGI ANCHE: Google Cardboard, la nostra recensione (video e Vine) Ironia a parte, per chi non lo conoscesse, Cardboard è il più originale gadget dato in regalo ai partecipanti al Google I/O di quest’anno, e consiste sostanzialmente in un cartone opportunamente ripiegato, con all’interno un paio di lenti, che grazie ad un’apposita app per smartphone diventa un antesignano dei caschi per realtà virtuale, dimostrando come si possa ottenere un buon risultato anche con una spesa davvero irrisoria (se volete vederci una frecciatina da parte di Google contro Facebook ed Oculus Rift siete liberissimi di farlo).

This is repeated until the box is stolen. Has something like this been done before? If you’re wondering what’s in the box, here’s a mostly complete inventory. The current plan for the Travelling Hacker Box is to bounce across the United States for the circumference of the Earth until departing for more exotic lands. Repair Manuals for Every Thing.
