Fun with chips: #1 MC1441 bit rate generator

I’m easily pleased. Leave me alone with a breadboard, multimeter, oscilloscope and a previously unencountered IC, and I can amuse myself for hours. Well, minutes anyway. It’s fun to fire up a chip and watch it do its stuff. And even more fun if it’s an old chip. But before we get to the IC itself, let’s fill in some… Read more »

DIY joystick for the BBC Micro – part 6 – completed (definitely)

Just when you thought it was over… When we last saw this project it was complete except for stuffing the joystick into some kind of box. As that kind of mechanical stuff doesn’t interest me greatly (and I’m crap at it), I wasn’t going to bother with a post about this final step. But hey, I’m nothing if not a… Read more »

DIY joystick for the BBC Micro – part 5 – completed (pretty much)

Having got impatient waiting for my PCBs to arrive from China, I went ahead and cobbled together some interim solutions for this project. And what happens? The PCBs arrive the next day. These are the ‘fixed’ PCBs with the proper footprint for the DB15 connector. And what can I tell you? They work. There is one slight issue that I… Read more »

DIY joystick for the BBC Micro – part 4 – a quick lash-up

While waiting for revised PCBs to arrive from China, I figured the time would be well spent learning a little more about the BBC Micro’s analogue port. And I have taken delivery of a couple of DB15 breakout boards, which meant I could try wiring up the joystick, albeit in a crude and temporary way. One joystick needs to send… Read more »

DIY joystick for the BBC Micro – part 3

Ah well, another valuable lesson learned. The PCBs for my homemade joystick, designed to work with the BBC Micro and Master, should have been very simple. They are very simple. And yet I still managed to screw up. The PCBs for both the main adapter, which plugs directly into the computer, and the connector for the joystick arrived the same… Read more »

DIY joystick for the BBC Micro – part 2

In the first part I described the interface between two RJ45 Ethernet sockets and the BBC Micro’s analogue port. The idea behind using RJ45 connectors is that you can use any old Ethernet cable to connect the joysticks. But as these are homemade joysticks, they’ll need RJ45 sockets of their own into which one can plug the other end of… Read more »

The original web

      No Comments on The original web

Next year will mark the 30th anniversary of the world wide web. And if you want to get a feel for how far the web has come, try experiencing what it was like in those heady days of December 1990. Tim Berners-Lee (now Sir Tim) built the original web while at The European Organisation for Nuclear Research (CERN) as a… Read more »
