Original PS3 remotes are scares nowadays and seeing that the PS3 is now almost 15 years old and Sony has stopped manufacturing them for a while now. Chances are that you might have an old PS3 remote that is not functioning as it should, or might be completely haywire (without […]

Going Bare Metal on the ATTiny85

Whenever I reach for the ATTiny85 I usually just use Arduino to program it, meaning the Arduino IDE and libraries. But the other day I was glancing over its datasheet and realized again how relatively simple this microcontroller is. So how hard could it be to shave off some layers […]

Arduboy

Running Arduboy on an Arduino Nano

A couple of months back I stumbled upon Arduboy, a mini handheld game console which draws inspiration from the original Gameboy by Nintendo. As you can deduce from its name it is powered by Arduino. What this means is that it uses an Arduino compatible chip (the ATMega32u4) and can […]

How to access a database from an App

In the previous post, Writing an Android application – investigating Xamarin Forms, I looked at how to get a basic Android application running on my phone. Most applications’ purpose are to represent data to the user in some way and in most cases this data is stored in a database. This […]

Where is the centre of gravity of a self-balancing robot?

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 […]

Low cost STM32F3 board

If you are looking for a STM32F3 board for your next project it might just be worth your while to consider the SP Racing F3 board. In a previous post I discussed how you can program an old Naze32 flight controller board using Arduino. While writing it I also looked […]
