Well, not exactly on the Beeb – more like via the Beeb. Ever since I built my copy of Grant Searle’s Multicomp I’ve had a hankering to hook it up to my BBC Master. There’s really no good reason to do this. The Zolastar 2000 (as I inexplicably called it) has perfectly good keyboard and VGA interfaces. And yet… Maybe it’s because… Read more »
Someone in a BBC Micro community on Google+ asked members to post pictures of their setups. So I quickly snapped this. There’s quite a lot going on in there – at least, there will be when I get the time to finish it. Alongside the BBC Master Turbo is a single 3.5in FDD and the TurboMMC storage device that I… Read more »
Keyboards are very person things. What suits one person won’t suit another. And I’m very, very picky. After 35 years of using computers, I know what I like, and what I like is what I’m typing on right now. I’ve always been a fan of keyboards with a positive click. The classic IBM keyboard with a buckling spring was my idea… Read more »
Much as I enjoy the truly retro experience of using floppy disks, they can become a bore. For my BBC Master Turbo, I have two disks I use a lot – one with ROM images, the other with the software I’m working on at any given moment. And the wrong one is always in the drive. I wanted to buy… Read more »
Well, this is exciting. My PiDP kit has just arrived from Oscar Vermeulen. I couldn’t resist pealing back the protective cover on the acrylic front panel. It looks fantastic – and will be so much better when it has all the blinkenlights. I haven’t decided yet whether I will use one of the Raspberry Pi A boards I have lying… Read more »
I was raised in an eight-bit era. My first computer was a Sinclair Spectrum, but I hated the dead-flesh keys and the clumsy method of editing Basic programs. So I upgraded quickly to a BBC Micro (first B, then Master). But while I cut my teeth on Z80- and 6502-based micros, there’s lots I missed out on – stuff I… Read more »
So I bought an Acorn BBC Master Turbo… Again. My introduction to computing – my gateway drug, if you will – was a Sinclair Spectrum 48K. I ordered one at the time of launch and then waited. And waited. And eventually a friend sold me his (he’d been earlier in the queue) and I cancelled my order. He’d decided the… Read more »
There’s a lot about this picture that makes me happy. Maybe it’s my age. Maybe it’s some stuff that I’ve been going through. But whatever the cause, I’ve developed a serious retro-computing bug. I’m going to get into details over a series of posts, but just a quick explanation of what you see here. In the foreground is a BBC… Read more »
The dawn clock is working well. To recap, here’s how it works: And here’s a basic description of how it works (more info & functions in previous posts): One hour before alarm time (configurable), the first LED is switched on. Subsequent LEDs are switched on at the rate of one each minute. To simulate dawn, the first 8 LEDs are… Read more »
The software for the dawn clock is written in Python. And no, I’m not going to upload it to GitHub, or anywhere else for that matter. There are two reasons for this: first, it needs work still; and second, it would take too much explaining, not least because it uses loads of my hand-rolled libraries and classes for the Raspberry… Read more »
My first big disappointment with the Raspberry Pi was the audio output from the headphone jack. When I built my first dawn clock, using an Arduino, I had to buy a separate shield for audio output, and even that was severely limited. With the RPi, I thought, life will be easy because all the audio stuff I need is built-in…. Read more »
One of the problems with my Arduino-powered dawn clock was that 10 LEDs just don’t put out enough light. I wanted a lot more for the Mk.II, but that then raises the issue of how they are controlled. Cascading shift register ICs would be one way to go. I decided, instead, to go with I2C port expanders. I selected the… Read more »
I don’t like waking up. I need easing into the day, slowly and carefully, especially in Winter. My wife is the same, which is why she bought a ‘dawn clock’. This is an alarm clock with a light that fades up slowly, over the course of 90 minutes, before sounding the alarm. It’s a fine device and we still use… Read more »
[UPDATE 8 Mar 2016: This is now an old post and many of the links have had to be removed because they no longer work. Things have generally moved on and so the information here is almost certainly out of date. I’ve left this here for historical amusement only.] [Updated 17 May 2012] A few weeks ago I managed to… Read more »
