Bluey, BLE Development Board Supports NFC

Development boards are assistant tools that help engineers and enthusiasts to become familiarized with hardware development. They simplify the process of controlling and programming hardware, such as microcontrollers and microprocessors. Electronut Labs, an embedded systems consulting company, had produced its new BLE development board “Bluey” with a set of useful sensors and NFC support. Bluey is an open s ...

AUGMENTED ARTHROPOD GETS A SELF-BALANCING RIDE

There are many people who find being around insects uncomfortable. This is understandable, and only likely to get worse as technology gives these multi-legged critters augmented bodies to roam around with. [tech_support], for one, welcomes our new arthropod overlords, and has even built them a sweet new ride to get around in. The build follows the usual hallmarks of a self-balancing bot, with a couple of in ...

FPV drone teardown

My lower-midrange Hubsan X4+ FPV drone got stuck in a tree in the middle of winter. We managed to knock it down a couple of months ago (the drone, not the tree), while there was still lots of snow to cushion the fall. After weathering the elements for over a month, it appeared to be mostly fine, except…one motor was seized. On the plus side – teardown excuse. I confess this isn’t a full teardown. The 720p c ...

NXP’s MMA8451QR1 Accelerometer

Process computer designs usually start out with an accelerometer. As reliability problems creep in, making the switch to a more “professional” solution is beneficial. Accelerometers are based on the MEMS principle: instead of being a purely solid-state affair, the inside of the chip contains a micromechanical motion sensor along with a small mass. In addition to that, a set of transducer circuits are provid ...

Air pressure sensors in smartphones

Today’s smartphones utilize a wide array of accelerometers, gyroscopes and various other sensors in their designs. Relatively unknown is the barometric pressure sensor, which measures air pressure. These sensors are currently being integrated into premium-grade smartphones, but are also becoming more common in mainstream phones or wearables such as fitness trackers and Internet of Things (IoT) applications. ...

DC Motor Speed Control using GY 521 Gyro/Accelerometer and Arduino

In this article, we are going to control two motors by using the GY-521 accelerometer module. The speed of the motor will increase or decrease upon moving the GY-521 module up or down. On moving the Gy-521 towards the downside, the speed of the first motor will decrease and the speed of the other motor will increase; while on moving the GY-521 towards the upward side, the speed of the second motor will decr ...

Project: Gesture Controlled Mouse (Air Mouse) Using Arduino & Accelerometer

AIR Mouse is also called gesture-controlled mouse and it works based on hand gesture. In this project an accelerometer is used for measuring the tilt of hand in X and Y direction and moves the cursor according the tilt. In the project two types of circuit are used, one is the transmitter circuit and other is the receiver circuit. Transmitter circuit makes use of MPU6050 series of accelerometer, which is con ...

How to Build an Air Guitar With Arduino, Aka the AIRduino Guitar

The idea here is to build a wearable virtual guitar that is to be controlled with two hands much like playing Air Guitar. It has been created and prototyped during a two weeks project at ChalmersUniversity (Sweden) for a Physical Computing class. The aim is to get the feeling of playing a real guitar. The AIRduino Guitar is made of one glove and one stick. The glove is used to set the tone and the stick to ...
