This summer seems to be an excellent opportunity for home repair and improvement. If you're looking for something fun and colorful to spruce up your home, check out this awesome Raspberry Pi-powered LED staircase project by Reddit user chocolate_dingy.
The project concept is simple enough, it uses a motion sensor to detect when someone is walking on the stairs. There are LED strips corresponding with each step. The Pi will send a signal to light up each step depending on the location data received from the sensor.
According to the creator, the whole setup relies on a single sonar sensor. This is used to measure distance while ascending the steps. The sensor information is relayed to the Pi so it can process the location information.
Hmmm, might be an easy (and relatively cheap) way to play around with Tor and learn a bit more about this anonymizing service. -- Douglas Adafruit’s Onion Pi is a Tor proxy that makes your web traffic anonymous, allowing you to use the internet free of snoopers and any kind of surveillance. Follow Adafruit’s tutorial on setting up Onion Pi and you’re on your way to a peaceful anonymous browsing experience. Tor is an onion routing service – every internet packet goes through 3 layers of relays before going to your destination. This makes it much harder for the server you are accessing (or anyone snooping on your Internet use) to figure out who you are and where you are coming from.
