ikalogic.com launched "IkaScope" a new wireless oscilloscope probe that is able to make measurements directly on your mobile phone or your laptop. IkaScope transfers measured signals over high speed wifi connection and it will remember your home or office access points. It will work...

TeamVenture-Bit tipped us with their kickstarter campaign. It's about a closed loop motor upgrade kit that will enable your 3D printer to print faster, silently and more consistently. Check it out. Boasting an advanced PID compensation system that detects issues while your 3D printer...

robert @ kandrsmith.org has a detailed article comparing the most common Humidity sensors. He writes: Previous experiments looked at comparing a set of six Aosong DHT22/AM2302 and compared the Aosong DHT22/AM2302 with the Aosong DHT11 and Sensirion SHT71. Here I have added five new...

ams AG, a multinational semiconductor manufacturer and provider of high performance sensors and analog ICs, had announced the AS7221, an integrated white-tunable smart lighting manager that can be controlled through its network connection by means of simple text-based...

JeVois, which can be translated from French as: I see, is an open-source quad-core camera that can be connected easily with your project whether you are using Arduino, Raspberry Pi or just running it on your PC. JeVois contains a video sensor, quad-core CPU, USB video and a serial port in...

The voltage-controlled current source circuit can be used to drive a constant current into a signal or pump laser diode. This simple linear driver provides a cleaner drive current into a laser diode than switching PWM drivers. The basic circuit is that of a Howland current pump with a...
