I got a couple of Microsemi’s C900502 10.525 GHz X-band Doppler radar motion sensors a while ago. This batch was made in UK and had “UK patents 2243495 and/or 2253108 apply” printed on the case. I have seen a teardown of an HB100 Doppler radar module before and was wondering if I this one is […]

Puck.js is a low energy smart device which can be programmed and debugged wirelessly with JavaScript. It is both multi-functional and easy to use. This beacon uses a custom circuit board with the latest Nordic chip, Bluetooth LE, Infrared transmitter, NFC, magnetometer, temperature sensor, RGB LEDs, and much more. Unlike other beacons, Puck.js comes with the

It’s wasn’t so long ago that RC transmitters, at least ones worth owning, were expensive pieces of gear. Even more recently than that, the idea of an RC transmitter running an open source firmware would have been considered a pipe dream. Yet today buying cheap imported transmitters and flashing a community developed firmware (if it
This project describes a DIY wireless temperature and humidity monitor for kids’ or infant’s room using the Arduino platform, and inexpensive and easily available ASK transmitter/receiver modules. On the transmitting end, an Arduino nano senses the ambient room temperature and humidity using the DHT22 sensor and transmits the data to a receiving end Arduino over

“Drone The Quadcopter” is an featured UAV. I design my project with F450 arm in X-mode design. The full operation takes place via a Flysky FSCT6 remote control unit which gives a better operating range of 800 Meter to 1.2KM. If you are a beginner in this field then you are on the right place.
Connect your door to the Cloud and open it from everywhere. Story The Doorbell is a great example of how to connect your devices to Arduino Cloud and make them talk to each other. The Doorbell allows you to open the door from everywhere as long as a WiFi network is available. The project is
Ultrasonic Blind Walking Stick According to the WHO, about 30 million people are estimated to be permanently blind worldwide. These people are totally dependent on others. They even cannot walk on their own. We have created designed and built an “Ultrasonic Blind Walking Stick” device which will help blind people to walk with ease independently.

Water Level Indicator Using Arduino Wireless Water Level Indicator Using Ultrasonic sensor & Arduino is an amazing and very useful project. The objective of this project is to notify the user the amount of water that is present in the overhead water tank. This project can be further enhanced to control the water level in

If you’re like me, you don like buying stuff that’s ready-to-go, but rather build one yourself. We usually spend more money, but it’s way more satisfying ? I really didn’t want to buy an overly expensive 32ch FPV LCD receiver, so I made my own DIY 32ch FPV 5.8ghz LCD, that is compatible with EVERY transmitter on
Recently I’ve found this piece of electronic on the dumpster, it was looking interesting – compact case with battery holder, LCD display, temperature and humidity sensor. It has also radio transmitter, but I’m not interested in it since I don’t have the receiver station. I decided to bring it back to life. It seems that
