Paul Rako@ edn.com discuss about thermal design in electronics and how to design your board to dissipate it effectively. If you have high-powered LEDS, or a power supply, or are trying to control larger motors, you have to get a lot of heat out of your circuit boards. The classic way...

Raspberry Pi carries a lot of horsepower inside to handle the realtime audio and add some effects to it. The only limitation is it does not have a built-in sound card, but it is manageable using an external USB soundcard. PiOSCBOX is an attempt to make a low-cost, stand-alone audio...

ShenZhen Ai-thinker CO.,a leading enterprise in the Internet of Things (IoT) industry and the maker of the ESP-12E module, had launched a new killer module: $3.60 GSM GPRS A6 Module! Providing a chip cheaper than the popular ESP8266 seems to be promising and opens doors for future IoT...

NXP’s accelerometer chip MMA8450Q, provides orientation detection on handheld devices: This application note targets the portrait/landscape orientation detection feature which has become standard in many hand-held electronic devices. Additionally, this application note aims to...

Inspired by an interest in spreading the concepts of FPGA, and because its ability to overcome most of other platforms limitations such as IO, memory, and peripherals, technolomaniac had worked on developing the first Arduino FPGA shield. A Field-Programmable Gate Array (FPGA) is...

Audio projects become smaller over time with the rapid advancement of technology. A traditional power supply is still considered large compared to audio projects size constraints and it may not fit such delicate applications that need to deliver a good sound with zero noise. Jan...

USB connections can transfer both information and power. UsbSafe² is a device for protecting USB-connected hardware from both excessive voltage, current and unauthorized data access. Unfortunately, the practice of “juice jacking” (accessing data from a device connected to a...

Knowing the amount of alcohol you drunk is becoming easier using the iBreathe Breathalyzer project by Dave Clarke. You just have to blow in the alcohol sensor, then it pings the result to a smartphone app and to the cloud to document it as a table so you can see alcohol intake through...
