Although ChatGPT is unlikely to be replacing programmers anytime soon, it can be a useful coding assistant. In this article, we will investigate how you can use ChatGPT (GPT-3.5) as a programming tool, and compare it to the earlier model found in the Open AI Playground (GPT-3). For simplicity, we…

With OpenAI releasing the latest iteration of its large language model, GPT-4 (Generative Pre-trained Transformer 4), we thought we would take it’s free little brother for a spin. ChatGPT currently uses GPT-3.5, a smaller and faster version of the GPT-3 model. In this article we will investigate using large language…

Our new prototype boards from PCBWay look fantastic! We have changed some components as explained in Part 6, and altered the board layout. Assembly is straight forward when all the parts fit. In Part 7, we continue development of the ESC firmware, starting with voltage and current monitoring. …

We blame this particular detour on Arduino! Our Raven Flight Controller Software is based on the Nano 33 BLE family of boards. A critical part of our flight firmware is the Attitude and Heading Reference System (AHRS). …

In part 6 we pull together all the theory from the previous parts into an integrated schematic and PCB. We have received the version 1.0 prototype PCB’s from PCBWay, and there are some problems with our design! We explain what they are and how we fix them in version 1.1.

Using the TTGO T-Watch Library — Part 1 of this series described setting up the Arduino Development Environment for the T-Watch, and Part 2 will provide details of the TTGO T-Watch Library (which is great but has a poorly documented API).

Using the Arduino IDE to program the LILYGO T-WATCH-2020 v1 — why is this so hard? LILYGO are a chinese company who sell products based on open-source hardware and software. The T-WATCH-2020 (Figure 1) is an ESP32 based 1.54" touch display “smart” watch. Make sure that you read the entire…

Excessive current will quickly destroy our ESC. The solution is to monitor the motor current. The obvious approach is to include a series shunt resistor in the motor windings path to ground. The voltage drop across the shunt resistor varies linearly with respect to the motor current (V = IR)…
