Meet the world's worse mouse design ever. The Atari ST mouse. Amiga owners liked their tank mice, we ST owners didn't like ours. It was square, uncomfortable and prone to breaking quite easily.
Mine is broken, I try to fix it. I fail. But along the way I get to figure out how it works, which was worth the effort.

I upgrade my BBC Micro so that it can run DOS using a Raspberry Pi, a Gotek floppy emulator and replacement floppy drive controller. Mostly this is a video about me learning how to troubleshoot random problems.

Come with me for a nostalgic trip around my Atari ST that I had has a child that has been sat unopened for the past 10 years. What will it be like inside? Have all the capacitors leaked? Is the motherboard corroded? What upgrades did I do to it, and do they still work?
In this video I go through the hardware, what I used to do with the Atari ST and make a list of future improvements and fixes to make.
This is part one of an ongoing series where I try to restore and upgrade my own personal Atari ST that I've had since I was 13. I want to turn it into a functional machine again, adding all the upgrades I could never afford as a child. Then I'd like to use it for some programming, DTP and other "real" computer tasks that I did actually use it for when it was my current computer.
In future videos I will be building an ACSI2SD hard disk adaptor, upgrading the RAM and using it for some serious period-accurate computing.

Building and testing the RC2014 Joystick Interface. This was a reasonably simple build, but I did have to slightly modify the board to make it work with my joystick. Also I was accidentally sent some wrong components, so now it's just a one joystick interface. The incorrect components sent to me have given me an idea for a future build though!

It's Halloween, programming is an art form and there's a darker side to it. Come with me in this fun video as I explore several languages that hate you and are trying to make your life difficult, before we go off down the rabbit hole and find some truly horrific examples of real programming.
There's languages that are hard to read, languages that are deliberately hard to understand with nonsensical rules and syntax. Then there's the true evil cooked up at 3am when programmers really need to get their job finished and nobody cares how they get it done.
No, this video is not just a trip through the Esolangs website picking out the usual suspects, it gets far far worse. Did you ever think regular expressions were a good idea, or write CGI programs in Perl? Maybe you're a seasoned C programmer and have had a look at the madness on display in the Obfuscated C contest.

Let's look at how to make an 8bit computer produce graphics normally seen on an Amiga.
The Spectrum Next contains extra hardware that lets us very accurately control when things happen relative to the screen being drawn. This is done using a piece of hardware called the "copper".
The copper is a processor external to the main CPU and can be given a list of instructions to follow that are synchronised to the generation of the screen. By cleverly manipulating the Spectrum Next's registers we can create some impressive visual effects normally only seen on 16 bit machines like the Amiga.
In this video I explain how to create the classic copper bars effect, some nice gradient backgrounds and parallax scrolling. The full source for this is available on my github, linked below and a detailed explanation of the code is on my website also linked below.
If you manage to make anything with this, let me know in the comments or send me a message on Twitter - @ncot_tech

How can there be a USB to RCA cable, it makes no sense. And what about a VGA to RCA lead? That can't be a thing either!
Come, explore these bizarre and non-standard cables that I found while shopping in a local discount store. These are PC data cables that simply don't make any sense. There's no way you can have a USB lead that contains composite video RCA connectors on the end of it. Nor can you simply stick a VGA connector on the end of those same RCA connectors and expect it to work. What exactly is going on?!
