Creating an ESP8266 Based Wireless Thermometer

Mon, 16 Dec 2019 00:00:00 +0000

I’ve been taking a look at InluxData’s TICK stack and figuring out some ESP8266 chips that I recently purchased. I always like to come up with practical projects to do when I’m learning about some new tech. When my dad came to me asking me to keep an eye on the temperature of his house while he was out of town, I knew exactly what I needed to build. It got even better when he told me his plan.

Automatic Bicycle

The Mechatronics class at South Dakota School of Mines & Technology has students form groups for a maze solving robot and free projects. My group decided to make an automatically shifting bicycle for our free project. We set up the bicycle to monitor the current speed and change the current gear in order to get the maximum workout.

Finding the speed

The bicycle tracked speeds at two locations on the bike. The first was the wheel speed. This let us know that the bike was actually moving and making progress. The second location was at the crank. This let us know when the rider might be coasting or if they are doing a lot of leg work without making much movement progress.

Gesture Control Mouse Input

The project for my Sophomore Design class at South Dakota School of Mines & Technology. For our semester long project, my group decided to make a wearable device that could translate hand gestures into mouse input for a computer. We nicknamed the device “The BAND” as an acronym of the involved members first names.

Reading Hand Gestures

To read the user’s hand position, we used an electromyography (EMG) sensor attached to the forearm with silver coated fabric and conductive gel. Whenever a muscle flexes in the human body it releases a very small amount of voltage.
