Cheap homemade 30 MHz – 6 GHz vector network analyzer
https://www.electronics-lab.com/cheap-homemade-30-mhz-6-ghz-vector-network-analyzer/
Henrik Forstén has done amazing job designing a homemade vector analyzer with the goal to fit it’s budget of 200EUR. The design is open source and available on github. Vector network analyzer (VNA) are used to measure scattering parameters of high frequency circuits. When frequency is high enough the reflections of the waves start to […]

Siglent oscilloscope SDS1102X review
https://www.electronics-lab.com/review-siglent-oscilloscope-sds1102x/
Harry Baggen @ elektormagazine.com reviews the Siglent SDS1102X oscilloscope. Before we take a look at the instrument itself, I would like to say something about the characteristics of an oscilloscope for ‘small users’. What do you really need for your daily tasks? Even the cheapest models from Chinese manufacturers already have a sample rate of […]

Inkjet printing of text or photos as solar cells
https://www.electronics-lab.com/inkjet-printing-text-photos-solar-cells/
by Denis Meyer @ elektormagazine.com: Research is in progress at the University of Aalto in Finland on the development of a process for inkjet printing of text, photos or any illustrations as solar cells. The idea is not new but these researchers are covering new ground which will allow the use of ordinary materials. According […]
Combo sensors fit wearable devices
https://www.electronics-lab.com/combo-sensors-fit-wearable-devices/
Two combination accelerometer-gyro sensors, the KXG07 and KXG08 from Kionix, a subsidiary of Rohm, provide six axes of motion sensing. Both devices feature a configurable low-power architecture and a large 4096-byte FIFO buffer with timestamps for use in gaming systems, smart phones, and wearable devices. by Susan Nordyk @ edn.com Unlike conventional sensor signal-detection methods […]

“myDevices”, creators of IoT platform Cayenne, announced in a press release a partnership with Arduino to integrate Arduino support in their system. The partnership seems to be with Arduino SRL not with Arduino LLC. The currently supported Arduino boards, beside variety of sensors and actuators, are: Arduino Due Arduino Leonardo Arduino Mega Arduino Nano Arduino […]
D7S Vibration Sensor From Omron
https://www.electronics-lab.com/d7s-vibration-sensor-omron/
Omron announced a new seismic sensor and claims it’s the world’s smallest in size. D7S sensor is a MEMS 3-axis acceleration sensor featuring OMRON’s unique SI value calculation algorithm, which has a high correlation with the seismic intensity scale that indicates the magnitude of an earthquake and provides higher-precision judgment of seismic intensity scales. The […]
Arduino Geiger–Müller counter with LCD display
https://www.electronics-lab.com/arduino-geiger-muller-counter-lcd-display/
Bob tipped us with his latest project. It’s a custom Arduino shield able to communicate with a Geiger-Muller counter and display data on a LCD display. The data are displayed in two layouts: bar graph of the pulses in one minute interval and histogram of the gathered data. In the previous posts I’ve described a […]
