Feel like someone is snooping on you? Browse anonymously anywhere you go with the Onion Pi Tor proxy. This is a fun weekend project that uses a Raspberry Pi, a USB WiFi adapter and Ethernet cable to create a small, low-power and portable privacy Pi. Plug the Ethernet cable into any Internet provider in your home, work, hotel or conference/event. Power up the Pi with the micro USB cable to your laptop or to the wall adapter. The Pi will boot up and create a new secure wireless access point called Onion Pi. Connecting to that access point will automatically route any web browsing from your computer through the anonymizing Tor network.
When I first saw the Drawdio at Maker Faire I knew it would be a great project for beginners: A lot of fun with instant gratification! Essentially, it's a very simple musical synthesizer that uses the conductive properties of pencil graphite to create different sounds. The result is a fun toy that lets you draw musical instruments on any piece of paper.
This is actually not any sort of product or public project (!) - its something I designed to help me evaluate solar panels and how they act when charging batteries. Normally this requires a lot of multimeters and its a bit of a pain to do if you have to constantly change out panels. So I decided I would build a specialized tool that would assist me.
A good front-light is essential, not only for being seen, but to see the road. LED lamps will not illuminate the road, and they can be too dim for cars to see you (1W or better LEDs are quite nice as headlamps.) I offer here a simple (but high-quality) design to build your own 5 or 10W halogen lamp, which runs off of a rechargeable 7.2V or 7.4V Lithium Ion battery pack.
The Brain Machine provides you with a fun, easy way to meditate, all the while being very photogenic! They work with lights and sounds that pulse at a 14-minute-long meditation sequence of brainwave frequencies. Your brain synchronizes to this meditation sequence, and you meditate. It's that easy! And the beautiful colors and patterns you vividly imagine along the way make it fun and enjoyable.
In 1970, John Conway came up with a 1-player game called Game of Life. The Game of Life is a mathematical game that simulates 'colonies' that grow or die based on how crowded or lonely they are and is known for the way it creates a beautiful organic display out of randomness. Here is a design for a simple electronic project that plays Conway's Game of Life. Make one kit and keep it on your desk, or attach multiple kit modules together to create a large display.
Adafruit is a high-tech company, run by fairly young people. All of us working here have spent our lives with computers, technology, and the Internet. So it's not surprising that software and software-as-services (SaaS) are an essential part of running Adafruit. We're constantly on the lookout for useful new tools that can help Adafruit run efficiently, and cleanly.
