This is part of a series of posts covering the development of a self-balancing robot: Modelling an inverted pendulum Building a self-balancing robot This post The mathematical model of an inverter pendulum previously developed for the self-balancing robot, needs three parameters to accurately represent reality. These are Weight of the […]
Introduction Looking for a professional review of the Nikon D780? Want to know how much noise to expect at ISO 51200? Need an in-depth synopsis of the new features carried over from the Nikon Z6? Well, then you are looking at the wrong page, sorry. If you are however looking […]
This is part of a series of posts covering the development of a self-balancing robot: Modelling an inverted pendulum This post Dertermining the centre of gravity for a self-balancing robot Previously we investigated how to model an inverted pendulum. It is now time to go ahead and build the […]
This is part of a series of posts covering the development of a self-balancing robot: This post Building a self-balancing robot Dertermining the centre of gravity for a self-balancing robot Aim Accurately model an inverted pendulum to use for control algorithms development for physical implementation. Personal goal: refresh basic understanding […]
I love e-ink displays. Their ability to make something digital seem just a little bit analogue intrigues me and I just had to make anything that makes use of one. Like many, many other people on the internet that turned out to be a weather station. The initial aim, seeing […]
Part 1, part 2 and part 3 of this build can be found in the links. In this post we will look at how to complete the build now that we have Retropie running on the Raspberry Pi, the screen working and an enclosure to put everything in. Controller The initial planning […]
Part 1 and part 2 of this build can be found in links. The size of the enclosure, and the whole system, was completely dictated by the size of the screen I decided to use. The initial idea was to buy cheap portable game systems from eBay, remove whatever was […]
