RoboBee – A Flying Microbot That Can Perform Search And Rescue Missions

RoboBee – A Flying Microbot That Can Perform Search And Rescue Missions

Inspired by the biology of a bee, researchers at the Wyss Institute developed RoboBees, man-made microbots that could perform endless roles in agriculture or disaster relief. A RoboBee is about half the size of a paper clip, weighs less than one-tenth of a gram, and flies using materials that contract when an electric pulse is applied. Now, they […]

Rotary Encoder with Arduino and Nokia 5110 LCD Tutorial

Rotary Encoder with Arduino and Nokia 5110 LCD Tutorial

Introduction Today we will take a look at using a rotary encoder with Arduino and displaying rotation data on the Nokia 5110 LCD display. A rotary encoder is an electro-mechanical device that converts angular position or the rotation of a shaft into analog or digital values. They are mainly of two types, absolute and incremental

1.7g Dual Axis IMEMS Accelerometer Using ADXL203

+/- 1.7g Dual-Axis IMEMS Accelerometer Using ADXL203

The ADXL203 Module  is high precision, low power, complete dual-axis accelerometers with signal conditioned voltage outputs, all on a single, monolithic IC. The ADXL203 measure acceleration with a full-scale range of ±1.7 g, ±5 g, or ±18 g. The ADXL203 can measure both dynamic acceleration (for example, vibration) and static acceleration (for example, gravity).The typical

Radioactivity detection using very simple ionization chamber and a single J FET transistor

Radioactivity detection using very simple ionization chamber and a single J-FET transistor

Today I will show a very simple ionization chamber that can detect radioactivity. I was able to detect with it ionizing radiation from a smoke detector (Am241 isotope). It’s also immune to electromagnetic interference (EMI) due to a good shielding. This device doesn’t explicitly use any power supply. It’s connected to a multimeter set to measure resistance,

Open Source NB IoT Shield for Arduino

Open-Source NB-IoT Shield for Arduino

Introduction With the emergence of low-power IoT devices with cellular connectivity and the phase-out of 2G (with only T-mobile supporting 2G/GSM until 2020), everything is moving toward LTE and this has left many people scrambling to find better solutions. However, this has also left many hobbyists facepalming with legacy 2G technology like the SIM800-series modules

MEC extender – and you’re a level higher

MEC extender – and you’re a level higher

We already know, that Switches MEC Unimec switch in up to eight ways and also that they´re available as momentary or alternate (latching). UNIMEC switches feature perhaps only one “disadvantage” – that on the same PCB no other higher components can be used (which would be higher than the switch). If you´re satisfied with the UNIMEC features, but despite
