It started as a vague concept - we had been keen to experiment with a Raspberry Pi for a while, so we started to form a concept around creating a robot to play a musical instrument. Lots of suggestions were put forward including a robot that plays a set of minature doll's drums, but we settled on the idea of using a set of metalic chimes because they were easier to source, and so that we could create a robot to play some simple musical notes.
Some people call it the “Etsy for hardware”, some other “the indie marketplace for open source hardware”, even if being open is not a requirement. Tindie’s mission consists of connecting the world’s small, hardware businesses with customers all over the world and today starts a cool initiative called Open Designs and Kickbacks. When sellers create a new product, they will be able to select a project the product is a derivative from, and enter the % of sales that will go to the open hardware project.
The handheld biosensor was developed by researchers at the University of Illinois, Urbana-Champaign. A series of lenses and filters in the cradle mirror those found in larger, more expensive laboratory devices. Together, the cradle and app transform a smartphone into a tool that can detect toxins and bacteria, spot water contamination and identify allergens in food.
A few months ago, I was having a conversation with my friend Nami, who works at a company called Loftwork . Loftwork is a design services firm and also the parent company of Fabcafe in Tokyo. She asked me if I wanted to help out with a project in the company to create a Makers group. The main goal of the group was to find DIY solutions to improve the office. They didn’t have a lot of experience in making things themselves so they asked me and a friend of mine, Joe Moross from Safecast, to help out.
Making a camera seems to be an impossible task, here we have an open source D.I.Y. digital camera created by Coralie Gourguechon. It's assembled with cardboard and power by the famous open source Arduino.
In fiddling around with PHP on a Raspberry Pi running on a Debian Linux OS more or less directly from a terminal mode, I realized that the focus (in my case) was getting the Linux commands right and very little with actually writing PHP programs.
Your favorite plants need plenty of water to grow. If you keep forgetting to water your house plants you might be interested in this plant watering alarm device called Chirp. Chirp uses capacitive humidity sensing technique to measure the moisture level in the soil and alerts the user through short chirps when it is time to water the plant. Based on the amount of ambient light detected by the on-board light sensor, Chirp detects day and night condition. It is very considerate and remains silent during the night time
