Improved Boost Converter Circuit ⚠️ Important Safety Notice This post is for educational demonstration only. While I have years of experience in electronics, this circuit involves high-voltage switching systems that can be dangerous if mismanaged. Please read the Full Safety Disclaimer at the bottom of this post before considering any practical work. This post is a sequel to the previous post on boost converters. If you have not read the first post, I strongly recommend reading it first, as it explains the theory of operation covered in this post. You can read the first post here . In the previous post, we constructed a simple boost converter on a breadboard. The results, however, were not particularly impressive. In this post, the circuit has been redesigned with improved components, and this time we will be driving an actual load rather than just a resistor. Updated Circuit Schematic Since the theory of operation was already covered in the previous post, the focus here will be o...
Bideford Railway Heritage Centre I was up in Barnstaple back in May 2025 as I was on the gorgeous Tarka Line (or the North Devon Line). It's been a railway line that I've been wanting to go on since my first year in Exeter and finally, I've got a chance to do so. In this post, you'll be joining me on this trip up north to explore North Devon's lost railways. Tarka Line Map (Source: https://commons.wikimedia.org/w/index.php?curid=108960715) The Tarka line runs between Exeter and Barnstaple, serving various towns and villages in between, notably Crediton and Eggesford. It also serves a pub (Portsmouth Arms) and the middle of nowhere (Kings Nympton, with the village miles away from itself). A number of stops on this line are request stops, which means you need to notify the guard specifically if you want to get off, or flag down the driver if you want to get on, like hailing a bus) 158951 takes me to Barnstaple Shoutout to St David's Starbucks for calling me Brian...
