My country mild climate lets the sun to shine for the greatest part of the year, then tumble driers are not widely used and so we often use to drain clothes in the sun. What to do when a sudden rainfall comes? This project has been made for anyone drain clothes in the sun or, simply, needs an alert when it starts to rain. "Peggy" project is a simple portable rain traker that uses a rain sensor, 433 Mhz tran ...

Electronic market is full of devices called pedometer and fitness tracker. They counts the number of steps you have taken, distance you have covered, whether you are walking or running and bunch of other stuff. Ever wondered, how these devices perform such measurements. I decided to make one on my own and share the knowledge of making it with guys. In this instructable we will develop accelerometer data acc ...

For this first edition of the hardware teardown, we’re dissecting technology and lifestyle brand Withings’ cheapest activity and sleep tracker: the Withings GO.   Since they launched their first connected weighing scale back in 2010 (the WiFi Body Scale), I’ve been a big fan of Withings. They make beautiful products that integrate seamlessly with their online platform and that seem to have a very decent li ...

Makers, developers and electronic enthusiasts looking for a way to communicate with the Iridium satellite network, may be interested in the new circuit board created by Maker Buoy. Their latest developer on board offers a solar powered GPS tracker providing communications with Iridium, due to its ability to be attached to a Feather form factor board, Adafruit has added it to its Feather list of components. ...

If you would prefer to build your very own DIY heart rate monitor, rather than purchase an expensive smartwatch or fitness tracker. You may be interested in a project published to the Hackster.io website earlier this year providing instructions on how to create a simple wearable heart rate monitor using an Arduino Nano R3. The tiny Arduino development board has been combined with a generic nRF24 Module toge ...

Over the last several months, [Aaron Christophel] has been working on creating a custom firmware for cheap fitness trackers. His current target is the “D6 Tracker” from a company called MPOW, which can be had for as little as $7 USD. The ultimate goal is to make it so anyone will be able to write their own custom firmware for this gadget using the Arduino IDE, and with the release of his new Android ap ...

The Radio Amateur Satellite Corporation, AMSAT, recently designated RadFxSat as AO-91 after its successful deployment from a Delta II rocket as a secondary payload to NASA’s JPSS-1. RadFxSat is the first of several AMSAT satellites which are flying a Maximum Power Point Tracker (MPPT) designed and built by Brent and I as a continuation of our Rochester Institute of Technology (RIT) senior design project. Th ...

The power tracker is an IOT based device that helps us to keep track of our power consumption. It also alerts us when we are exceeding the power usage limit. With this device, we don’t have to wait until the end of the month to know our power usage. Daily usage alert helps us control our power consumption. [gallery columns="1" size="full" ids="31731,31732"] This is a small compact device that we just have t ...

Use Amazon Alexa Devices and Sensors to find where objects are in home, or your office. Story A ton of inanimate objects are part of our life, and we add them day after day. We spend inordinate amount of time searching for these in times of need. These inanimate objects can be categorized by frequency of use as follows 1) Uses on a daily basis Glasses, keys, phones, cables, chargers, laptops, wallets, purse ...

Arduino Solar Tracker Solar energy is one of the fastest growing industries in the world; today more than 65 GW energy is produced by solar power. Since solar energy is renewable, it is a good power source, especially for developing countries. In this project, I am going to show you how to make a solar tracker using Arduino Nano. The solar panel tracker is designed to follow the sun movement so that maximum ...
