Arduino / Raspberry Pi Internet Radio

This is a project for Arduino and Raspberry Pi to make an Internet Radio, aimed at intermediate skill level. Some familiarity with Linux usage will be beneficial (or access to someone who can help out if required). Raspberry Pi runs mpd music player daemon to receive and decode the internet radio stream. ALSA running on the Raspberry Pi provides the sound through either the Jack Socket or the HDMI output. A ...

Internet of My Own Things

The Internet of Things has a different meaning for different people. For some, it means monitoring room temperatures from a mobile phone, whereas for other, it is controlling garden lighting from a laptop computer. For sports-minded people, it might mean logging their heart rate in real-time to a cloud service. Is there a common denominator between this wide range of different applications? Our answer is Ai ...

Just Veggin with an Arduino Beetbox

Bring Touch Control to the Arduino. Use interesting touch sensors like Carrots or Beets to make a "Beetbox". In this project you will learn: * How to use the Cap Sense library to make Arduino responsive to touch * How adding a Wave Shield (and some root vegetables), you can make a "Beetbox" The Principles of Capacitive Touch Sensing For the Beetbox we use three sense channels. To start we'll implement one t ...

Make a proper PCB exposure unit out of a cheap UV nail curing lamp

What do PCB production and fake fingernails have in common? They both use UV light sources of high intensity and, as luck would have it, those light sources have exactly the same wavelength. Only the ones for PCB production are usually quite costly and the ones for fake fingernails are a bit more competitively priced. This instructable is about how to use such a device to build a low cost light source, suit ...

Useless Box

Story Fascinated by this humorous anthropomorphic idea on instructables that left me philosophizing deeply about the essence of art, I decided to make this a project after witnessing many ruthless battles between human and robot on youtube.   How does it work? The Arduino "listens" to the state of the switch and actuates the servo when the switch is activated. In the OFF state, the Arduino sends the se ...

Provocation: Urban Encounters

Description Urban Encounters is our imagination of the future of interactive surfaces within our 5x5x5 site. The crosswalk "island" we chose at the corner of Shattuck and Center in downtown Berkeley promotes an interesting combination of isolation, stuck-ness and loneliness. To bring out these themes into the physical world, we decided to modify existing objects to support traditionally web-only interaction ...

HestiaPi – Open Smart Thermostat

Okay, there are too many open source home automations out there but whenever I tried to look into making any of these I ended up with a bitter taste because of one or a few of the following reasons: The software part was open but the hardware was based on boards either too complicated to produce myself economically or simply proprietary that I could only buy ready The sensors/parts were too expensive It was ...

Kroebe Lights

Brainstorming Process After selecting Kroeber Fountain as our location of interest, we began to notice that it was a place at which people would congregate without interacting with one another. The fountain’s shape - most notably, its tiered steps - affords it the ability to serve as a seat where multiple people can sit in close proximity to one another and still manage to treat each other like strangers. W ...
