FitBark / Comb9 Integration
- How to get a low battery notification and more...I recently purchased a FitBark dog activity tracker. I always check now to see if there is some kind of API available with products like these, so that you can capture and use the data in ways other than the manufacturer intended - it turns out with FitBark there is. Although you might think the primary purpose of a device like this is to see just how much running around your dog does, you kind of already know that - though the ability to compare that to other dogs can either make you feel smug, or guilty.
Extreme Aquarium Automation
- Exposé on home-made, handmade, aquarium automation setupThis post describes my current aquarium setup, in particular, the technical, custom designed parts of it. There is a lot of monitoring and control going on; though virtually all of it is hidden behind the scenes, as my aim has always to create a natural looking environment. An aquarium is an eco-system, some aspects of it can stay in natural balance with maintenance, and other parts require active control. Things are more complicated with plants - I recently have become more serious about growing plants.
Energenie Integration with Python on a Raspberry Pi
- Using pyenergenie to do Energenie automation with out need for the cloudIt is disappointing what IoT hardware manufacturers provide regarding software with their products. I don’t want to single out Energenie - at least they created a tremendous hackable radio board specifically for the Raspberry Pi. The ENER314-RT provides two-way communication with all Energenie products including all their power switches, energy monitors and radiator valves. This means that you don’t need to buy an Energenie Gateway MIHO001, and you also don’t need cloud connectivity and the worry that somebody might be snooping on your data.

A Brief History of NetKernel
- on extracting release data over nine year periodI’ve just finished working on exposing a complete change history for NetKernel for the period from the release of NetKernel 4.0, nine years ago. Previously our mechanism for publicly exposing this information has been solely through the, once weekly, newsletters. However that medium is unstructured which meant it was hard to get an overview of changes and check for specific releases for any particular package. Since the release of NetKernel 4, we introduced a repository approach to releasing updates to NetKernel.

External Request ProfilerWe’ve been working recently with a client, on a solution, revolving around crunching large volumes of data. The scale of data meant that even on a large cluster the computation takes many hours. The usual mode of operation for these compute jobs is to set them off in the evening, and return the next working day to see the results. I was working with them to capture some engineering figures and statistics to assess the performance and opportunities to optimise or re-design.

My Experience Building an Alexa Skill
- Headline: it is actually pretty easyBack in November I attended a talk on creating your own Amazon Alexa Skill at Bristech. It’s been something I’ve wanted to play with for a while, so when Amazon had their Black Friday sale I couldn’t resist. I was pleasantly surprised by Amazon’s own tutorial using Lambda: Alexa Python Tutorial - Build a voice experience in 5 minutes or less. It really was quite simple and quick. Amazon have worked hard to make it easy for you to get a custom skill up and running on real hardware.
Technical Debt and EntropyI seem to find myself with a lot of unproductive time - time when I can’t be working on real problems - problems that need access to tools such as a coding environment, terminal, internet searching, and somewhere to capture notes. Situations such as walking the dog, driving, and getting simple chores done are examples of these times. Times like this though, are good for thinking, and recently i’ve been thinking a lot about the concept of technical debt.
On The BeachI’ve had a horrible ray traced pebbly beach scene framed on my wall for a long time now that I really wanted to redo. I’ve used a bit of free time at Christmas along with a major new release of Cheetah3d to do that. Here are a few of the things I created.
