Slow Arduino IDE with ESP-32 Devices

Slow Arduino IDE with ESP-32 Devices

There is a noticeable difference on how long it takes for a sketch for the ESP-32 to compile when using a Windows based system, versus using a Linux based system. Depending on the sketch, this difference can be up to 10 times, which could frustrate developers. The suggestions online point to anti virus as the cause, with disabling the anti virus or adding exceptions as the workaround. Others recommend using Visual Studio instead of the Arduino IDE. This post will…

ESP-32 Cam Low Light Use

ESP-32 Cam Low Light Use

This post will cover some use cases of the ESP-32 Cam module in low or no light conditions. The software and hardware of the ESP-32 Cam module will modified for this purpose. Some additional hardware examples will be introduced as well. Lastly, the use of FFMpeg will be demonstrated to further enhance the images gathered from the ESP-32 cam module. What are some reasons for the ESP-32 Cam module to be used in low or no light environments? The more…

Visualizing Data with Processing

Visualizing Data with Processing

The purpose of this post is to demonstrate how to use Processing to present data in a visual way. The methods used in this post will be based on the work done by M.Furkan Bahat. Source – https://mfurkanbahat.blogspot.com/2014/11/artificial-horizon-and-compass-using.html The hardware used in this demonstration will be the following: GY-521 MPU6050 Arduino Uno ESP32-Cam ESP32-USB-Module Patch wiring USB cables Windows 10 laptop The MPU6050 is connected to the Arduino Uno using the following pin connections, as shown in the images below….

Modified Volantex Ranger 600 Controller

Modified Volantex Ranger 600 Controller

The stock Volantex Ranger 600 TX is as basic as any TX can get. The undocumented throw reversals prompted a closer look at the controller. The terms controller and TX apply to the hand held radio controller used to operate the remote controlled plane, TX will be used going forward. One item that was replaced with a yellow LED was the beep indicator. Since a lot of bench testing was going to take place, the blinking LED would be less…

ESP-32 Flight Datalogger – Thrown off

ESP-32 Flight Datalogger – Thrown off

With a couple of flights done successfully, it was time to go back to the location where the earlier plane Bryce was lost. The area seemed to have something that may have influenced the loss, in addition to other factors. The park is rather small, so anyone walking on the field was a no go. With the occasional walker, the park was clear. The ESP32-Cam system was activated to get a GPS lock, while the routine of preflight was done….

ESP-32 Flight Datalogger – Rise Above It

ESP-32 Flight Datalogger – Rise Above It

The data gathered from the flights revealed some interesting things. The first was that the amount of detected networks increased with elevation. The two flight locations weren’t close to any dense residential areas. At ground level, those networks were limited to the immediate area. However, once in the air, that number increased because they were now line of sight. The data logger also captured the three strongest networks detected, along with their RSSI values. Although the network numbers increased, the…

ESP-32 Flight Datalogger – Flight of Leia

ESP-32 Flight Datalogger – Flight of Leia

Many will think of the hair when they hear this name, unless born before 1960 or after 2010, then those numbers might be fewer. This became the name of the remote control plane due to the large pylons on each side of the fuselage. The plane center of gravity was almost a perfect match to the original. The weight was evenly placed but it was noticeably more than the stock 55 grams. It was flight day after a couple of…

ESP-32 Flight Datalogger – 3D Printing Parts

ESP-32 Flight Datalogger – 3D Printing Parts

Creating a nose cone for a pylon seems trivial. There are numerous tutorials and instructional videos on crafting. In fact, there is so much material available, a large amount of time could be used just reviewing a portion of what’s available. Time is not trivial though, so finding proven method is what motivated the use of 3D printing. 3D printing became the basis for creating the hardware that was hard to find. There is an open community of designers that…

ESP-32 Flight Datalogger – Hardware Build

ESP-32 Flight Datalogger – Hardware Build

Since the ESP32-Cam project was going to be installed on a remote controlled plane, keeping things as light as possible was the primary concern. This required a tally of what each item weighed and how best to build around that. All aircraft have a center of gravity that is used as a reference point. That point is where the aircraft balances front to back or side to side. Any change in that point can influence how the aircraft will fly….

ESP-32 Flight Datalogger – Supply Chain Break

ESP-32 Flight Datalogger – Supply Chain Break

Hardware build can begin once the design, development, and testing phases are complete. The ESP32-Cam project development hardware could have been reused. The problem with reuse is that the hardware is no longer available in a development capacity and the project is locked. If any damage or modification occurs during the hardware build, this can cause delays. For that reason, additional parts were sourced and purchased with the intent of using them for the build. There were plenty of ESP32-Cam…
