Recently, there was a lot of buzz as the 32bit general purpose GigaDevice GD32V which is based on RISC-V open architecture as well as the Longan Nano development board with LCD display were launched into the board market. Compared to the formerly released GD32 Arm Cortex-M3 microcontroller, the GD32V RISC-V MCU is expected to deliver 15% performance improvement in Coremark and […]
Electromagnetic interference problems can be a real headache to debug. If you need to prove what causes your WiFi to slow down or your digital TV signal to drop, then the ability to measure electromagnetic fields (EMF) can be a big help. Professional equipment is often very expensive, but building an EMF detector yourself is

As its name suggests, the CO2 Display project is a small CO2 gas sensor to be plugged into USB to easily track indoor and outdoor pollution.The CO2 level is displayed live, but it is possible with the small application provided in the documentation to generate capture samples in image (in png format) and in list
Coin-operated machines have a longer history than you might think. Ancient temples used them to dispense, for example, holy water to the faithful in return for their coins. Old payphones rang a bell when you inserted a coin so the operator knew you paid. Old pinball machines had a wire to catch things with holes
Mass sensing startup Sorex Sensors Ltd. (Cambridge, England) has launched its first product, a particulate sensor along with a development kit. By Peter Clarke @ eenewseurope.com The Sorex sensor is designed for use in air purifier systems and in semiconductor manufacturing equipment, such as atomic layer deposition tools, where it can monitor amounts and rates. It
