Included in the jacket are an Arduino microprocessor, an alcohol sensor, and a series of LED’s that “provide an elegant solution to the drink driving problem.” A breathalyzer located in the pocket of the jacket, analyses the sample and then lights, that are stitched into the forearm, indicate how drunk you are. The LED lights glow when alcohol is detected and the brighter they glow, the worse you are.

Bicyclists receive a lot of honk-based grief from car drivers who perceive them as slow and in the way, and when drivers misjudge a bicycle’s speed, it can cause “right hook” collisions that kill several bicyclists each year. This lightweight night-cycling vest displays your current speed in glowing, 7-inch-tall numbers easily visible to cars. On the back, an Arduino microcontroller reads input from an off-the-shelf bike speedometer sensor, and then switches power to sewn-in numerals made from electroluminescent (EL) wire.

From B-Reel’s secret laboratory comes a brain-bending experimental project utilising a number of cutting edge tech tools. B-Reel’s UK creative director Riccardo Giraldi led the development of the project, and you can view the explanatory video here, as well as some of the creative musings in a write up below. [...] There are few commercial devices that claim to safely read your brain signals. We ended up choosing the Mindwave headset from Neurosky for this experiment because of its unobtrusive design and its affordable price.

There isn’t actually much new about this awesome DIY project, but it’s the way it brings the various parts together that has us impressed. Designed by Instructables user XenonJohn, with help from software developer David Findlay, the Magic Music Table RFID was designed to let a disable child (or other such handicapped user) select albums to play back from an iPod touch playlist. The iPod is connected to anArduino, which tells the device to start playing a particular track based on a selection made with RFIDcards. The whole setup is built into a coffee table and the RFID tags are sandwiched inside clear plastic blocks with the album art. You can see it in action in the video after the break and, if you’ve got the patience and skill, you can build your own using the directions at the source link.

Pinball machine will automatically power up at the preset time each day and then resets to display the current time, the year, the time the alarm is set for and the date month/day. Then as long as the GPS has a signal the time will update once a minute for the rest of the day.  At the time you would like to go to bed the Arduino will cut power to the game and it will remain off until the alarm time. Should you have a power failure in the night the machine will not lose it’s settings. If power is restored prior to the alarm time the machine will wake up as normal, otherwise the machine will wake up once power is restored.

If the game is powered on because it is not yet bed time and it is after the alarm time then at 12am, 1am or 1pm the game will do a full reset. This makes sure the clock hasn’t gotten off due to a stuck score reel, keeps the time in a 12 hour format and keeps the date display up to date.
