    Release script for SVN

    Friday, June 8th, 2012

    I am currently working on a project that comprises several components individually managed in SVN. These components are built and then linked in to the final binary. To makes things easier I wrote a release script that creates an editable commit message with the SVN revisions of the components and commits the final binary. I thought it might be useful to others so generalised it.

    The Sleeper Awakens

    Tuesday, May 1st, 2012

    This will be my first blog post in a very long time. Life has been busy and, in my day job, productive. Unfortunately this has meant that activities outside of work have been somewhat curtailed. But today I am ‘bunking off’ early as it is the monthly PHP NW meeting in Manchester so I am on a train heading across the country to it. This is giving me a chance to write this! (more…)

    My BBC Micro and Me

    Friday, December 2nd, 2011

    The BBC Microcomputer is 30 years old. The BBC News web site had an article about it but from the article you would think that only males benefited from it. Well it wasn’t just the boys who had fun with them! (Photo © Anachrocomputer) (more…)

    The BBC Model B Microcomputer keyboard – How it works

    Wednesday, April 27th, 2011

    As part of my BBC Micro PC project (more about this later) I need to turn the keyboard in a BBC Micro in to a USB hid device. I could just rip the insides out of a PC USB keyboard and solder wires on to the back off all the key switches but that seems somewhat messy. So I decided to design a micro-controller circuit to read the keyboard and to appear as a standard USB HID device. The neatest solution is to have the micro-controller drivng the keyboard circuitry the same was as the BBC Micro main board does. This post explains how the keyboard circuit works. (more…)

    Upgrading your UK T-Mobile Google G1 (HTC Dream) to Android 2.x

    Friday, October 22nd, 2010

    I’m currently developing a new project. Its a bluetooth enabled bracelet. I wanted to write an iPhone app to control it. However, much as I like my iPhone 4, Apple’s policy about locking the thing down sucks. So I then looked at writing an Android application for my G1. The problem with that is that bluetooth support only arrived in Android 2.0 and T-Mobile/HTC ceased upgrades at 1.6 on the G1. Since my G1 is two years old and out of contract I decided to be brave and upgrade it to Android 2.2. Note the G1 is called the HTC Dream in many markets.

    Announcing http://projects.cyberspice.org.uk/

    Wednesday, September 29th, 2010

    I am pleased to say that I have finally gotten around to starting to publish details of the hardware projects I have been working on.

    I have created a new site http://projects.cyberspice.org.uk/ which contains all the details of these projects. Over the next few days I will be updating it with the details of Beebthernet, my programmable earrings and so on. Each of the projects will be described in detail and links to software and schematic downloads provided.

    The first documented project is my ethernet for a BBC Microcomputer project known as Beebthernet.

    Enumerating note data in Flickr using PHP

    Friday, September 24th, 2010

    Flickr provides a comprehensive API to access its data. It also has a very neat notes facility that allows you to add notes to a region of an image which pop-up when you mouse over the relevant area. Flickr provides API calls to add, edit and delete notes but not to enumerate notes associated with an image. To do that you have to do a little more work.

    DPC 2010

    Thursday, July 15th, 2010

    A couple of weeks ago I went to the Dutch PHP Conference 2010 and I had an amazing time. The event was held in Amsterdam at the RAI centre. The primary sponsor was iBuildings and the entire event was organised by the totally awesome Lornajane.

    When DPC 2010 announced the call for papers I submitted both a proposal for a tutorial on PHP extensions and one for a talk on web services. Both were excepted. I had proposed both half day and full day versions of the tutorial the organisers chose the full day version. This turned out to be a lot of work. Basically I would be talking for 6 hours in four 90 minute slots.
