New version of a favorite RFID module ID12LA will enable you to implement RFID into your device even more easily thanks to a wide range of supply voltage. Literally “globally known” with an integrated antenna – ID12 and its familiar like for example ID2 or ID20 have earned a big popularity thanks to a flawless […]

A long, long time ago there was a great Design Idea for a simple gadget to find a bad bulb in a series-connected string of Christmas lights: This is really simple and works great, but it exposes the user to potentially lethal line voltages. The PROBE in the figure above is inserted into the light […]

Two DIY micro-controller based USB connected electronic units which along with the Texas Instruments Analog System Lab Starter kit and a laptop permit you to conduct analog experiments anywhere. It would be wonderful  if senior students and laboratory supervisors built these units so that they could be used in their laboratories by freshers. Aj-SigGen-PS   […]

I discovered a flaw in the current design that will only allow the controller to work with a connection to the computer and not to a microcontroller.  I’ve updated the schematic below and will fix the controller design.  I’ve added a project file below that also includes the fixed schematic. If you look at the […]

Create your own Beer Bottle LED Volume Unit Meter! This instructable will show you how to create a LED beer bottle VU Meter. A volume unit meter is a device that is used to display a relative volume of audio signals. Basically, sound gets converted into electricity, then amplified and run into a dedicated IC […]

ORLANDO, Fla. — CES 2015 debuts the future of smartphones coming from all places, Moscow, where mother-company Yota Devices is partially owned by the Russian government. Shown in the E-Ink booth at CES, the YotaPhone, as its called, is not yet available in the U.S. and its a good thing, since that gives Apple, Samsung […]

Scientists at the Nanyang Technological University (NTU) in Singapore have developed a smart window that is able to tint itself blue, partially blocking incoming light, without the need for an external power source. The device also functions as a small transparent battery that recharges on its own simply by interacting with the oxygen in its […]

There may be a lot of RGB LED Drivers out there, but this one is a bit different, its versatile, small, cheap, and is simple to control. A potentiometer with built in switch is used for the controls. A quick press, switches between color cycling and solid color select modes. Pressing in on the dial and […]
