[Steve Hoefer] shared an interesting solution for visually impaired people. It measures the distance to things and translates that into pressure on the wrist.[…] It’s wrist mounted and senses objects from about 1 inch (2 cm) to 10 feet (3.5m). It has generally fast response time (fractions of a second) to quickly navigate complex environments. It’s not the […]
[Micha] has a washing machine with an inaccurate time data displayed on the front panel. How to solve this? Since it is located in his basement, he hated having to check on the machine continually to know when his clothes were done. Instead of hauling up and down the stairs over and over, he decided […]
Matt Richardson has a great blog post on Make about using an Arduino to read the closed-captioning stream from a TV using a video experimenters shield, then muting the TV whenever the name of an annoying celebrity is heard. Besides being a great idea, it’s a nicely made explanatory video. Nice work, Matt! […]
[Paul Ferragout] realized a strange printer, with an incorporated program to print any image using a time-based algorithm. According to the grey value of a pixel on an image, the felt pen remains in contact with the blotting paper for relative periods of time. The Arduino-controlled Time Print Machine uses an algorithm to “paint” images — […]
Arduino forum user [Blibo] shares its 2.4 Ghz spectrum analyzer project on the forum. The project is based on the CYWM6935 board (wireless), an Atmega 328 and a Nokia 5110 LCD- I finished the (mostly) permanent version of my 2.4ghz spectrum analyzer, and soldered it up. I included 3 modes for scanning (fast, slow, and […]
If your office suffers of “conference room abuse” you should build your own “roominator” to coordinate it: Conference Room Abuse is where people 2 or more people randomly grab a conference without any regard to the schedule for the room. Its a problem many companies face. [Rapleaf] tried to solve this by creating a system […]
A steam-powered record turntable made out of juck & re-used things. This was made with small steam engine with a boiler crafted from a copper water pipe and carved some wood for the custom platter and base. Add some magnets, a coil for a pickup and a servo that is controlled by Arduino. via [hacklog] […]
Nice Oscar Belle Two Band Transistor Radio (1960s) hacked with Arduino. What it is really doing is playing 24 music tracks that I preloaded onto an SD card in WAV format. There are also 10 tuning noises tracks that get played when the tuner is turned. Because this is the first time I did this […]
[Daniel Huhndt] hacked a typewriter to let it sending his dato over Skype: the Stype. With the help of “some solenoids, relays, pushbuttons, some parts of a cheap keyboard, an arduino mega and a mac mini” , the typewriter can be used to send messages online. Whatever is typed into the paper gets sent, and the […]
Sebastian Alegria, a 14 years old Chilean teen created an earthquake warning system based on Arduino, an earthquake detector (bought for less 100 $) and an ethernet shield. Alegria’s rudimentary yet effective system comes from having survived Chile’s own earthquakes last year and seeing the devastation that covered Japan earlier this year. Keen on finding […]
