Review: Exploring Raspberry Pi by Derek Molloy

This book was published in 2016 but I’d always dismissed it because I assumed it would be too basic. After all, I’ve been messing around with the Raspberry Pi for some years now and I really had no use for a book that spends the first couple of chapters saying ‘this is what an LED looks like and here’s how… Read more »

Raspberry Pi: creating a cross-development environment for ARM

So here’s a confession: I hate make files. And I’m really not all that keen on the whole compilation thing, with all those flags and whatnot. Why? Because I’m lazy. But of late I’ve felt myself drawn back to C++. There is something about the language that both appeals to me and repulses me. Mostly those make files. So this… Read more »

Apt-get and the curse of IPv6

      1 Comment on Apt-get and the curse of IPv6

Well that’s two hours of my life I’m never getting back. You know how sometimes you try to do a simple five-minute job and the damn thing just snowballs…? Well that was today. First a quick summary so you know what this is about – I was having problems with apt-get stalling when trying to use it on a Raspberry… Read more »

Dreambox: switching to plan A

      No Comments on Dreambox: switching to plan A

Planning is a good thing. Having your project mapped out before you start saves time and avoids wasteful detours and last-minute kludges. I should definitely do that some day. My approach to electronics is the same as my approach to writing software: just get started – it’ll all work out somehow. Luckily, I don’t write code or build electronic devices… Read more »

HMV1960: nothing succeeds like excess

So I’m finally getting somewhere with my HMV1960, a gutted valve radio that I’m using as a somewhat oversized case for a Raspberry Pi. It looks great with the keyboard I’ve just bought via Massdrop. I’ve replaced the original fabric-covered speaker section with some aluminium sheeting into which I set a display, an LED matrix and two speakers. Because I’m ham-fisted… Read more »

Dreambox: Raspberry Pi and Teensy, living in perfect harmony

Okay, so I couldn’t get the headline to scan to fit that godawful song, but here’s the thing: I mentioned before that my Dreambox project – a way of playing music to lull me to sleep – would be driven by a Raspberry Pi but would also involve a Teensy. And you probably want to know why. The answer is:… Read more »

Dreambox: making noise

      No Comments on Dreambox: making noise

For the past few weeks I’ve been lulling myself to sleep with the help of headband-mounted headphones and my iPhone. Now I’m building a bedside device that will play my carefully curated playlist of dream-inducing ambient music at the touch of a button. Unlike the Dream Machine I built for my More Significant Other,  which was based on the fabulous… Read more »

HMV 1960 valve radio Raspberry Pi case

So I was looking around for a case for a Raspberry Pi and I noticed this old radio gathering dust in the cupboard. And it all just got out of hand from there. The HMV Model 1376 valve radio dates from 1960. When I bought it in a junk shop for a few quid it was working. When I took it… Read more »

Next project: drifting off to sleep…

So after I built my wife her dream machine, I got jealous. I too would like to ease my way into sleep. After all, I’ve already built a machine to wake us up gently. So I decided to build my own dream machine. And at first, my plan was to simply make a replica of Trish’s, but loading music rather… Read more »

Something useful

      No Comments on Something useful

If you’re into retro computing, or building stuff based on SBCs such as the Raspberry Pi or BeagleBone, you’ll be familiar with a certain refrain from your significant other and even those you consider your friends. They’ll look at your latest project — perhaps a restoration of a 1980s home micro, or a simulation of a 1960s mini computer, or something… Read more »

Python on the PiDP

      No Comments on Python on the PiDP

I’m not really a C kind of person. And so when I finished building my PiDP kit, I immediately started thinking, ‘Wouldn’t it be nice to use all these switches and lights from Python?’ Because Python really is my kind of language. You can be properly expressive in it. And there’s not all that nasty business with make files. Fortunately,… Read more »

Networking VAX OpenVMS on SIMH & the Raspberry Pi

[Update 10/03/2017: some broken links were fixed] We’ve already had some fun getting a VAX up and running with OpenVMS under SIMH on a Raspberry Pi. And boy, what a mouthful that is. I’m building my installation on my lovely PiDP just because it seems appropriately retro. I mentioned at the time that the next step would be getting networking… Read more »

SIMH on the Raspberry Pi

      No Comments on SIMH on the Raspberry Pi

Installing the software for the PiDP, Oscar Vermeulen’s re-imagining of the PDP-8/I, couldn’t be easier. But that wasn’t going to stop me making life harder for myself. I mean, why do we play with machines like this? It’s to learn, to explore, to discover, to take things apart and occasionally to break them. I haven’t done that last one yet,… Read more »

Computing the ’60s – Raspberry Pi style

As soon as I heard of the PiDP I knew I would have to have one. Created by Oscar Vermeulen, whose KIM Uno kit I’d previously bought, it’s a brilliant recreation of a PDP-8/I using SIMH running on a Raspberry Pi. What’s more, it has loads of blinkenlights. So why did the kit sit in my office for eight months… Read more »
