There will come a point where you will want to store data which isn’t lost when your microprocessor loses power. This is particularly handy for storing calibration or configuration values, to save you having to re-calibrate some piece of hardware (e.g., IMUs, and servos) every time the power cycles. One…

Part 2 demonstrates the techniques used for finding the centre of gravity of our top and bottom hexagonal platforms and how to calculate the co-ordinates of the connection points on each edge. This step is glossed over by everyone! It is not until you try to actually code the formulaes…

The Stewart Platform, also known as a hexapod, motion base or parallel manipulator, is a mechanical system that consists of a platform connected to a fixed base through six independently actuated legs. This arrangement allows for precise and versatile motion control in all six degrees of freedom (DOF): three translational…

Work Life Balance is a load of rubbish. No such thing exists. There is only life and the things you choose to do with it, that may be work, or it may be something else. …

The Reefwing AHRS library provides an Attitude and Heading Reference System (AHRS) class for use with Arduino compatible boards. In Part 2 of this article we will explain how to use the library and provide hardware specific examples for the Arduino Nano, Nano 33 BLE, Nano 33 BLE SENSE (REV…

To provide compatability with the Reefwing AHRS Library, we have been forced to release libraries for the following IMUs: MPU6000/MPU6500 LSM9DS1 The control board that is used on our Stewart Platform (Figure 1 — this flight simulator will be the subject of a separate article), comes with an MPU6050, so…

While testing our updated Attitude and Heading Reference System (AHRS) library with a variety of IMUs, we found that there were not a lot of options for the MPU6500. The most popular library appears to be fastIMU, which supports a LOT of different IMU sensors. Unfortunately for us, this library…

ChatGPT is surprisingly good at coding simple websites. We had been reading about people generating browser based games using ChatGPT and decided to see if we could come up with the next Wordle. Our previous review of ChatGPT’s programming expertise was a bit of a mixed bag. Our conclusion was…
