Calculating Battery Life Using Power Consumption

Ryan Chen

I have added time remaining functionality to the power consumption board that I have. However, it is not refined and therefore has a few caveats for use. The program assumes that the battery is at full charge upon program start. While there is no current through the sensor, the time remaining wi...

ESP Wifi Module and Blynk Software

Ryan Chen

Recently, I have been working on connecting the ESP Wifi Module and the Blynk software. I have been looking into both emulation and ESP Now. Additionally, the Blynk software for controlling the motors does have capabilities with Bluetooth, so I will also be testing the Blynk software with my HC-05 m...

Motor Current Draw

Ryan Chen

I have been working on testing power consumption. Below are the results for the brushless and brushed dc motors we currently have. This means that with a 1000 mAh battery, we can run one of these motors for about seven hours. This result is quite good, but I need to extend the test for longer an...

Using the Arduino Nano With Motors and Wireless Modules

Ryan Chen

I have been working on taking power consumption measurements of the arduino nano control board, as well as the motors and wireless receivers. Unfortunately, Amazon had some problems with delivery and I was unable to receive the current reading board and the motor driver this week. I was planning on...

Testing Power Consumption of Motors

Ryan Chen

Recently, I have been working on testing the power consumption of motors. For this part of the experiment, I tested the HobbyPower 8520 Motors while paired with AAA batteries. This is working towards the future goal of understanding the maximum, minimum, and average flight times of given blimp syste...

FORAY Blimp Takes Flight

Ryan Chen

For testing this week, I used the Air Swimmer blimp and made different modifications to it. My end goal was to determine whether propellers or using a flapping motion was a more effective way of providing thrust for our balloon. First, I did some basic flight tests to see how well it moved around...

Foray Blimp Becoming Mobile

Ryan Chen

Foray Blimp Becoming Mobile Big Picture In order to build the optimal blimp for competition, we are currently focusing on modeling the different parts of the blimp’s movement. Specifically, movement in the horizontal plane and altitude control. In terms of horizontal plane movement, we are seekin...

A FORAY into Lighter-Than-Air Vehicles

Ryan Chen

A FORAY into Lighter Than Air Vehicles How can we create blimps that can outstrip competition in agility and speed? This was the initial question our team was posed with when embarking on this project. To solve it, we began with a "project proposal" outlining what we thought was the best method...
