Are Microcontrollers the Future of Electronics?

  Freescale (NXP) Kinetis KL25Z General Purpose Microcontroller Microcontrollers. As electronics students, you either love them or hate them. But there's no denying that microcontrollers are literally everywhere. I mean EVERYWHERE. You might not see them directly, but they are hiding in your smartphones and smartwatches, your microwave, and even your washing machine. Each serving various purposes. The fact that microcontrollers can handle tasks efficiently with very little power and minimum damage to your budget makes them ridiculously ubiquitous (oh look I learned a new word).  For those of you that are unfamiliar with microcontrollers, here's a quick microcontroller 101 for you. If you already know what they are, you may skip the following paragraph:  Microcontrollers, sometimes MCUs (MicroController Units), are basically a tiny computer in one single chip. You can program it to do specific things. For example, in a microwave, it listens to the buttons yo...

My Article On The Parish Magazine

River Exe Hey fellow humans! So last month I was approached by someone from the parish magazine editorial team of my local church, and I was asked to write a short article about my life in Exeter and etc. I'm very proud to say that it has been published recently. In order to preserve the authenticity of my writing and to share it with you all across the world, I'm posting the original version here, without revision by the parish magazine team. (Well, not that they changed a lot of stuff. I just want to show you the original version of my writing.) Heart in Exeter It is currently my second year studying at the University of Exeter. During these two years, I have fully experienced how wonderful this city is. But first, I would like to take you back to the beginning, if I may. Back when I was doing my A-levels at a college in Sussex, I was told many things about Exeter once I shared my plans to study there with my friends and teachers. All of them were positive. Everyone kept sayi...

My 2024 Wrapped

Myself at Exmouth, Devon As 2024 is coming to an end, I find myself reflecting on this incredible journey that 2024 has been. It was a year filled with challenges, explorations and constant suffering in the lab.  Here’s a recap of some of the highlights that made my 2024 truly unforgettable. January: Visiting St Austell and riding the HST Charlestown Harbour In the start of January, while everybody else is either partying or holidaying in the most touristy spots in the world, I hopped on a two-hour train ride down to the Cornish town of St Austell, a town famous for its brewery and one of the top 5 most dangerous small towns in Cornwall according to CrimeRate. Some of the locals even called it "St Awful". With that in mind, I hopped off the train and engaged in a lovely conversation with one of the locals, with his thick Cornish accent (I presume), the conversation didn't last very long until I just nod yes to everything he says. (I think at some point he asked me if I ea...

The Great Topsham March

The Great Topsham March It's a sunny Saturday with scattered clouds and gorgeous blue skies. What a perfect day for a walk.  I made my way from Exeter's city centre to the quay, where I start my walk along the River Exe down to Topsham and I've decided to name this walk "The Great Topsham March". Sounds cool, doesn't it?     The quay is pretty busy, with people drinking and relaxing under the sunlight. I stroll past the fish market, where a band is performing (Didn't understand a word of what they're singing.) and make my way down to Trews Weir.  Trews Weir Trews Weir was built to raise the water level for the Exeter ship canal, which is built by John Trew of Glamorgan (Hence the name Trews Weir). The weir was also used to provide water for a fulling mill, a cotton mill and a paper mill. You can learn more about the weir's history here .  I then made my way across Belle Isle Park, walking past runners, dog walkers and the elderly, and end up in Du...

Privileged Mainland Student Hassles Resident Cleaner

This post contains strong language. Viewer discretion is advised. Hi. Let me tell you a story. It's my first year in university and as an international student I'm required to live on campus resident halls until my second year. In each "house" within the halls, there's around 2 cleaners (at least for my house). The cleaners in charge of my "house" include one British 66-year-old bloke (Which I'll just refer to as "cleaner" below) and a Women.  Cleaner is in charge of cleaning mine and my roommate's room for 90% of the time. We always had a chat when he comes in and cleans my room, my kitchen and toilet etc. He normally comes on Wednesdays or Thursdays, which in normal school period, I'm probably away in a lecture. But during holidays or exam periods (when I'm writing this blog), I'm more likely to be in my room and this morning was no exception.  I was talking with cleaner this morning while he's cleaning my room, and he...

Ryan in Wales - Part 1 of 4

Ryan in Wales - Part 1 Wales. A country that nobody seemed to care about. When we talk about the UK, we instantly think of England, Scotland, Northen Ireland (Not so much) but not Wales... Well, unless you're from there.  Since I'm studying in the "partially beautiful" city of Exeter, I'm able to hop on a 2hr and 30m train ride to the capital of Wales: Cardiff. Now why would I want to visit Wales? It all started from January, when I was in my dorm, bored and doesn't want to do any schoolwork. I started a course on Duolingo, and I went for the most popular language of them all... Welsh. Yep. I'm learning Welsh on Duolingo.  Why? Why not?  Anyway, I hopped on the train on a cloudy afternoon on the 1st of April and embarked on my 2-and-a-half-hour journey to Cardiff, Wales. (There are faster options if you change at Bristol, but my train is cheaper and it's a direct train.) The train was pretty busy. A lovely woman was sitting on my reserved seat, asleep....

Pinebook: a laptop for $99 USD?

             Recently a laptop called 'Pinebook' has caught my attention. This laptop costs only $99 USD and It's running Linux. A laptop this cheap usually won't be 'user-friendly' because many corners were cut for lowering the expenses. But $99 dollars? This is really unheard of. So let's take a look of this $99 dollar laptop's specs.  This is the Pinebook's specs shown in Pine64's website. As you can see, It's armed with an 1.2 GHz Allwinner A64 quad core processor. This processor might not be familiar with some of you so let me tell you a little bit about it. The Allwinner A64 is a 64-bit tablet processor developed by Allwinner which is a Chinese company. It's got Quad core Arm Cortex-A53 processors and a Mali-400 GPU. No wonder it's running Linux. I'm not sure it'll got enough power to run Windows.  So the specs isn't the best, in fact it's pretty poor. But again, It's $99 dollars. What do you expect? This pro...
