Reclaimed wood was used to replace the stair treads in this stairwell but the knot holes were coming out. Broken glass and epoxy was used to fill the knot holes, a bunch of LED were added to let the knot holes light up. A motion sensor is used to light the stairs for 9 seconds which is just enough time to enjoy the look of the cool knot holes
Viktor has built a great looking project which is a PIC Microntroller based Dual Thermometer using two DS1820 1-Wire Sensors. This allows Viktor to monitor the exact temperature in his fridge and freezer at the same time. Since the sensors are 1-wire this means that they are really easy to wire to the board. “The temperature sensing part I used for this project is a high-precision 1-Wire digital thermometer

This Capricious Clock by our friend Pete Mills makes the second hand move in some strange ways which makes it makes the seconds tick by the way time sometimes feels. 🙂  “The code keeps track of the 1pps pulses coming from the quartz clock movement, it delays for
Dave Molmen has sent in the picture build log of his custom Exuberant Clock. The clock concept is very interesting.

The clock face moves the brass indicator across the minute number one per
Viktor sent in a great tutorial on How to Fix a Worn out Video Game Controller. Most remote controls use rubber membranes that have conductive end that press against the circuit board when pushed. The circuit board has some gold fingers that get shorted out to register the button press. Viktor uses some metal foil on the rubber membrane to bring the controller back to life. This trick should
 Tod from d’innovative wanted a way to control his garage door remotely. Have a look at his Wifi Garage Door Opener Project Build for some inspiration when you are ready to build yours. If you are looking for some other options be sure to check out some of the ones we have featured in the past. Thanks for sending this in Tod “A wifi garage door opener that
Laser shows are really cool, Matt from Openschemes cracks into one to show us what the inside looks like. “The device under investigation will be the CASA CTL-BM RGV Laser Show. This is a 3-beam laser projector with Red, Green, and Blu-Ray Violet lasers. It’s legal status for commercial use is doubtful at best, and the safety aspects are extremely suspect due to the use of DPSS green and
