Faucet Add-On Attempts to Save Water by Changing Colors

This augmented water device was rapidly developed during an H2O hackathon in Lausanne, Switzerland. It was built by a software engineer code-named [tamberg]. His creation contained an Arduino Uno, a strip of NeoPixels, a liquid flow sensor, and a tiny lithium-ion battery attached to a cut medical tube that was re-purposed for monitoring water use.

From the looks of it, this project addressed a specific problem and went on to solve it. The initial prototype showed a quick and dirty way to monitor precious water that is literally being flushed down the drain.

Steam Gauge Keeps Track of Your Internet Usage

There™s a certain appeal to analog gauges in a vastly digital world. [Ed Konowal] is a Network Operations Supervisor for a school district in Florida ” part of his job is to ensure a stable and fast internet connection, so he decided to make an internet usage gauge for his office.

What we really like about this hack is the fact that [Ed] had no idea how to do it. It™s a simple enough idea, right? Google was his friend and Ed started learning about all kinds of things. Raspberry Pi™s and Arduinos, wireless receiver/transmitters, servos and steppers, Python¦

Hands Free Recording “ Looks Silly but is Super Effective

While most hackers probably like to claim they™re good at everything, no one is good at filming one-handed. Setting up a tripod and adjusting it every shot can be tedious ” wouldn™t it be great if you could just film what you see?

That™s what inspired [Hans de Bruin] to make these camera goggles. He™s using those big old school safety glasses that you can remove the glass lenses from. From there he traced the outline and 3D printed an adapter that would fit snugly in the glasses while holding up a video camera ” He™s using a Chinese version ¦ Read the rest

Open Source GPU Released

Nearly a year ago, an extremely interesting project hit Kickstarter: an open source GPU, written for an FPGA. For reasons that are obvious in retrospect, the GPL-GPU Kickstarter was not funded, but that doesn™t mean these developers don™t believe in what they™re doing. The first version of this open source graphics processor has now been released, giving anyone with an interest a look at what a late-90s era GPU looks like on the inside, If you™re cool enough, there™s also enough supporting documentation to build your own.

Retrotechtacular: Forces Acting On An Airfoil

We™ve probably all experimented with a very clear demonstration of the basic principles of lift: if you™re riding in a car and you put your flattened hand out the window at different angles, your hand will rise and fall like an airplane™s wing, or airfoil. This week™s Retrotechtacular explains exactly how flight is possible through the principles of lift and drag. It™s an Army training documentary from 1941 titled śAerodynamics: Forces Acting on an Air Foilś.

What is an airfoil? Contextually speaking, it™s the shape of an airplane™s wing. In the face of pressure differences acting upon their ¦ Read the rest

A MIPI DSI Display Shield/HDMI Adapter

[Tomasz] tipped us about the well documented MIPI DSI Display Shield / HDMI Adapter he put on hackaday.io. The Display Serial Interface (DSI) is a high speed packet-based interface for delivering video data to recent LCD/OLED displays. It uses several differential data lanes which frequencies may reach 1 GHz depending on the resolution and frame rate required.

The board explained in the above diagram therefore allows any HDMI content to be played on the DSI-enabled scrap displays you may have lying around. It includes a 32MB DDR memory which serves as a frame buffer, so your śslowť Arduino platform ¦ Read the rest
