Project: #InventforGood Bat Vision

What a great, creative project for kids of all ages and a prototype for something that could be very useful. This project uses the LittleBits interlocking electronics kit, but it would be easily recreated using standard Arduino parts. It looks like even the code could be re-used, too. I have an ultrasonic sensor I picked up cheap and some other parts from an Arduino Start Kit. I think I might put this together just for the shear fun of it! See links for parts below.

#InventforGood Bat Vision

This device can detect the obstacles on your way using echolocation method just like bats do. It's like you have your own bat-friend who can accompany you wherever you go and tell you if there is something on your way that you cannot see.

It is a useful tool for blind people and for people working in the conditions of very low or no visibility. Of course, it can also be used for playing fun games.
The voice alert will turn on once you appear within a dangerous distance from the obstacle ahead.

It is based on the Arduino Bit. It drives the ultrasonic sensor and keeps measuring the distance from the objects ahead. The buzz alert indicates that the distance from the object is within 50 cm.

Onion Pi makes your web traffic anonymous via Open Electronics

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.

How to Build a Raspberry Pi-Powered Digital Photo Frame via Tom's Hardware

A digital photo frame is a small screen that can sit on your desk in your office or in your kitchen displaying your favorite pictures, changing at regular intervals. The first commercial digital photo frame was introduced in the 1990s shortly after the digital camera. Digital photo frames made a comeback in popularity during 2020, perhaps because people were staying at home more. In this tutorial, we’ll turn our Raspberry Pi into a digital photo frame using MagicMirror and the GooglePhotos module. Please note, we will skip installation of the 2-way mirror in the original Magic Mirror project. Consider this project, “Magic Mirror, without the mirror.” Read How to Build a Raspberry Pi-Powered Digital Photo Frame via Tom's Hardware An interesting link found among my daily reading

On my Mac/Windows PC…Disk Inventory X/WinDirStat

Disk Inventory X | WinDirStat   There comes a time in every computer user's life when they need to figure out why their hard drive is out of space and Disk Inventory X and WinDirStat are a great help. Their operation is pretty straightforward. Look at the hard drive directory and see what is taking up the most space. Then allow the user to prune, backup or other remove these files to free up some space. Simple, effective and very, very useful when you need it.
