 Guitar tuners are quite common these days. Only problem is that they use displays or LEDs to indicate how the tuning process is going. Sam from J44 Industries made a guitar tuner that a blind person can use for a charity called Remap. His design starts with an off the shelf guitar tuner, only problem with this one is that it used LEDs for visual feedback. He used
  Felipe La Rotta from Cocodrilabs had a noisy hamster wheel. Hamster wheels like most other mass produced pet items are made as cheap as possible, that means that you won’t find a smooth spinning bearing in your hamster wheel. His solution was to make a Hard Drive Hamster Wheel. Most of us have a few used hard drives sitting around that will never be powered up again and
 Thanks to lyberty5 for sending in his audio headset built from a SuperNES controller. “The controller was used as a base, I then rebuilt walls with bits of plastic and epoxy resin. I then used epoxy putty to model a circular shape, some bondo, and a lot of sanding. The whole thing was then painted. It’s not perfect and I’ve damaged the paint in some places. Also the controller
We have featured Matt Denton’s hexapod designs in the past. He has been spending some time working on a project that is a bit bigger than the previous ones! His new design which has been 4 years in the making called Mantis is a Hexapod Walking Machine. He has taken lots of pictures in the Facebook page (a few can be seen below). This video done by Daily Planet
Kerry Wong just finished his latest project, it is an Ethernet Temperature and Humidity Logger. “I used an ENC28J60 Ethernet module along with an ATmega328p microcontroller to log the temperature and humidity readings and then process the data on my web server for display. To plot the data points, I used Google Annotated Timeline so that you can easily zoom into the desired date/time range. “
Olivier van Herpt invented a machine called the Time Writer. It allows any graffiti artist in training to get their message out to the masses with the push of a button. An Arduino controls the action here. The Arduino pulses a number of relays which open and close paint nozzles. The paint mixture is pressurized using a re-purposed water fire extinguisher which conveniently has a valve just like a
Tobias Schmidt built a robot mechanism to time his tea brewing. It uses a Atmel ATmega8 microcontroller to run the show, a 2 line LCD display shows you how much time is left for the brew to complete. A motorized slide was made with two optical limit switches is used to dunk the tea bag into the cup. Tobias is willing to share the code with anyone that is
