Stupid BT router...
I have the misfortune to own a BT Business 2Wire router, and bleaklow.com sits behind that. A while back it threw a fit and reconfigured itself and when I beat it into submission I didn't notice that it had also lost the port mappings for bleaklow.com. ... |

Hints on creating 256-colour themes for vim
Most existing vim colour themes are designed for the graphical version of vim, gvim. They don't work properly at all if you are running vim in a terminal, and there are very few themes available for vim in terminal-mode. You are pretty much obliged to ... |

Childhood autism spikes in geek heartlands
From the New Scientist: Childhood autism is two to four times as common in Eindhoven, the centre of the Dutch information technology industry, as it is in two comparably sized Dutch cities with far fewer IT employees. The result supports the ... |

A mention on the Pragmatic Programmer
I was looking at my Google Analytics and noticed I was getting referrals from the Pragmatic Programmer site, specifically from an article in the April magazine issue entitled Advanced Arduino Hacking. Turns out they were using my Makefile.master as the ... |

EletroAxé with Carlinhos Brown
Carlinhos Brown is a colossus in Brazilian music, known not only for his solo musical career but also for the founding of Timbalada and for reviving the use of the Timbau, one of the instruments I (try to!) play. As part of this year's carnival in ... |

As it says, "Beautiful light performance"
Well, we did our first performance with the LED strips on Wednesday at Islington Mill in Manchester,and I'm relieved to say they worked flawlessly, even after one of the wheels was dropped just before the performance started! The lighting in the venue ... |

Connecting a HL1606 strip to an ATmega
I've been left a comment asking how the HL1606 strips are connected up to an Arduino. The wiring is really pretty simple, but depends on exactly which ATmega version you have, as the hardware SPI pins vary from MCU to MCU. The following assumes it's a ... |

I'm wheely pleased...
Last night I met up with Andy and Colin of The Travelling Light Circus at MadLab to finally finish off some the LED strips that I've been working on for so long. The original plan was for them to be worn, which would have meant splitting the 4 20-LED ... |

Openbench Logic Sniffer comes of age
A while back I bought a Openbench Logic Sniffer from Dangerous Prototypes. Whilst it kind-of worked it was most definitely alpha and really not much practical use - no big deal considering the low price. However everything is field-upgradable so I put ... |

Don't delay()
It's very common for Arduino sketches to use the delay() library routine to control timing when performing time-related operations such as LED animations. Unfortunately delay() is toxic if you need to do more than one thing at once - for example ... |

Optiboot on Arduino Pro Mini
The newer Arduino boards such as the Uno include a new bootloader that takes up about 1/4 of the size of the old one. That means some extra memory can be freed up for applications. The new bootloader is known as Optiboot, and the site says "Compatible ... |

Radio-controlled HL1606 strips
Well, I've finally finished the design and implementation of the radio-controlled LED strips I've been asked to make for The Travelling Light Circus. It's taken far longer than I expected, but I've learned an immense amount in the process. The ... |

Waiting for O(1)
Due to a misconfiguration the notification emails from my blog weren't reaching me, so I missed a couple of interesting comments on my earlier HL1606-related posts. The ones from Dan from over at Waiting for O(1) were particularly interesting, and he's ... |

Facebook lives up to my worst expectations
In January 2008 I made this prediction: it would be far more effective to use a Facebook application to harvest personal information whilst apparently offering a useful service, and then use the data elsewhere and/or at some time after the application ... |

Switch debouncing, the hard and the soft way
I'm using a quadrature encoder for my LED lights project, to allow the controller to select the pattern that is to be displayed. The encoder consists of two parts, a momentary push button switch activated by pushing the shaft down, and a rotary encoder, ... |
