Clever Clapper uses Claps and Laser Beams to control the Lights

at 6:15 pm. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks


Who says The Clapper is old technology? Pete Mills blows off the dust from the vintage tech and breaths new life into the idea. The new Clever Clapper uses Claps and Laser Beams to control the Lights!

 “In my version of the clapper if you clap twice within one second, the circuit toggles the lamp output.  On becomes off and vice versa. If you clap three times within one second, the lamps begin dimming up and down via PWM until a fourth clap is detected or a one minute timeout occurs, whichever comes first.  The brightness value is then stored and restored for subsequent toggling of the lights on/off with the two clap event.  I also added a relay output to turn on and off the moon lamp.  To trigger this relay, you shine a laser beam at the circuit to toggle it.  Laser beams begets moon beams. “


Sound Responsive Dress

Check out this Sound Responsive Dress which listens to the singers voice and adjusts accordingly. In the picture below you can see the electronics that run the dress mounted to the wall.

Thanks to Mitch for sending this in.

“It’s a sound-responsive dress that uses Processing (heavily using the Minim code library) and Arduino to map the singer’s voice onto an array of spinning strings. The strings, in turn, tug and pull at the singer’s dress.

In the attached photo, you can see the microphone in the foreground. Then, moving down the wall of electronics, you’ve got the Arduino and transistor array, the power source, a netbook running the Processing sketch, and finally a small mixer board.”

Learn Electronics with Snap Circuits

at 5:49 pm. Filed under DIY Hacks, Electronic Hacks, Toy Hacks


Breadboards make building circuits quite simple, how could it get any simpler that a breadboard? The answer is Snap Circuits. With the different component pieces all you need to do is snap them together to build your circuit, this might be a great way to learn circuits for the first time since the schematic is a picture of the actual build layout. Krash made a robot from them to demonstrate what can be made from them.


Bipedal Dynamic Stability Testing

James Burton from XRobots.co.uk has sent in the latest progress on his Bipedal Dynamic Stability Testing. Looks to be moving along very well.

“It’s about half the height of an average person and I built all the parts from scratch with hand tools. It’s basically intended as a development platform so I have some more to build and some more experiments to do, but I’m at the stage where I have dynamically stable walking using R/C style heading gyros intended for use with R/C helicopters. The whole thing is currently controlled with a single Picaxe-18X micro controller.”

Ikea Night Light controlled by an Android Phone

at 6:48 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks


If you ever wanted a way to control your night light from across the room you are in luck. Dan reverse engineered his Ikea night light and stuffed in a bunch of electronics so that it can now be controlled by an Android Phone. Of course remote control is just the beginning, a smart Android app could now easily use it to display the status of many things.

“It’s about a simple idea: take a cheap 3 colours Ikea night lamp, hack it by replacing its original MCU and adding a cheap serial bluetooth device and then write a simple Android app to control the lamp remotely from your phone !

This is just the beginning, imagine the possibilities once the phone has direct control over the colours and their respective intensities. You can make it light up in sync with some music, you can make it change colours depending on some e-mails you receive or your Facebook status, etc. …”



LED Illuminated Knot Hole Stair Lights

at 2:23 pm. Filed under DIY Hacks


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 as you walk up the stairs.

Via: Stair Lighting Blog

“Foot lights on our stairway are epoxy pools of glass in the knot holes. They are triggered by a light motion sensor modified to drive a solid state relay which in turn switches a Dell power supply driving 11.5 V to approximately 35 LED lights.”

PIC Microntroller based Dual Thermometer using two DS1820 1-Wire Sensors

at 12:03 pm. Filed under DIY Hacks, Electronic Hacks


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 chip from Dallas Semiconductors. There are a number of similar ones available; I used the DS1820 because I have a few of them left over from previous projects. This one uses the 1-Wire protocol to communicate with the PIC, doesn’t need any external components and it’s easy to be placed inside a fridge.”
