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 progressed even further and designed a hybrid RoboBee that can ...

Replacing a dead iPhone battery

About a week ago, in preparing to run some errands, I plugged my iPhone 4S into the charger in my car so that I could stream Pandora while I drove. Oddly, a “this accessory may not be supported” message appeared on-screen; when I unplugged and re-plugged the iPhone to the charger, it didn’t reappear, so I didn’t think anything more of it … until a half hour later, when the iPhone again alerted me, this time ...

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 rotary encoders. The output of the absolute encoders indicates the current posi ...

+/- 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 noise floor is 110 μg/√Hz, allowing ...

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, in this mode, the multimeter provides a small volt ...

DIY IKEA Wireless Qi Charging for the Hexiwear

The Achilles Heel of the Mikroelektronika Hexiwear is its charging: the charging and USB connector are only designed for a limited number of plug-unplug cycles, and it does not have a wireless charging capability like the Apple iWatch. Until now! I have built a DIY wireless charging system for the Hexiwear ? :   Wireless Qi Charging? IKEA!!!! I have been experimenting with wireless charing for a few we ...

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 from SIMCOM. Although these 2G and 3G mo ...
