Red Pitaya? E imprimam os vossos Cartões de Visita, um Inversor, e um Phone Roverbot

Red Pitaya? 

O que raios é isso?

É uma forma económica e Open Source, de equipar um Laboratório com Instrumentos de Medida e Controladores, ora eis uma bela Dica da Designspark:

Red Pitaya

Red Pitaya is an open source measurement and control tool replacing many expensive laboratory instruments at a surprising price tag. This powerful tool is at the heart of a revolutionary Red Pitaya Ecosystem, which facilitates discovering, experiencing, learning, developing and sharing a variety of applications.

Simple and Impressive Business Card Printer

Thingking

At some point most tinkerers and makers have to take the plunge into the real world - the world of suits and dividends and business cards. Without going completely "American Psycho" on your asses: business cards are important. In many ways they are our keys to the business world; the first impression making a massive impact, and potentially the difference between eating a Burger King in front of your computer and getting taken to a French restaurant for a business meeting.

E que tal controlarem um RoverBot com o vosso Smartphone, ou Computador, através da Wifi?
Façam de 007, por poco dinheiro, usando, é claro, um Arduino para construir isto:

DIY Phone Controlled Rover (Fast & Agile - FPV Drone)

ASCAS
Let's build a Bluetooth/ WiFi controlled FPV Drone! RoverBot is a highly educational Arduino based ATV-drone. It's simple to make, easy to program and is a great starter project for hobbyists! The bot is very fast and agile, not to mention of it carrying two "29,000 rpm" motors! It can surely outrun humans regardless of the terrain you're on!

This RoverBot is a soft prototype. My next agenda is to make v2.0 water resistant, shockproof and dirt-proof. The next one would probably carry metal-gearboxes and long range TX RX modules.
