My Samsung HT-C460 home cinema had started going into protection mode – it would display “PROT” on its screen and turn off after a few seconds. It’s an old cinema system with a DVD player that hasn’t been used in years (I only use it to feed the TV audio through), but I thought I’d …

After seeing the work done by Thomasz Mloduchowski and Colin Riley with managing to bridge the Raspberry Pi 4’s PCI-Express bus to a USB 3.0 port, and then seeing these comments on hack-a-day, I thought I would give it a go too! So, here’s a PCIe bridge “chip” that simply replaces the VL805 USB 3.0 …

Many years ago (September 2009) I made a simple bench power supply using an LT1083 7.5A linear regulator with adjustable output voltage designed to be used with a 19.5V 3.42A laptop power supply. It still works fine after years of abuse, but my choice of output power connectors was poor (3 pin headers, the sort …

What’s more annoying than having to pull the USB cable every 5 seconds to power cycle the project you’re working on? Especially when you’ve ran out of front USB ports and have to reach around the back of your PC. This project aims to make things a little bit easier by using a small push …

Having had a Toyota GT86 for a while I quite enjoyed the built-in rev alarm and winding the engine all the way round, until an old lady made it an insurance write off. Though, I did have the luxury of driving a BMW 430d M Sport hire car from my insurance for a few months. …

This is a library for use with the Si4463 radio IC from Silicon Labs, used (or will soon be) in some of my projects. The Si4463 is configurable in a ton of different ways with options for modulation, packet format, CRC algorithms and has a high output power of up to +20dBm (100mW). The Si4463 …
