Automating documentation using Python

One of the tasks for this week was cleaning up after an infrastructure move and then updating all the documentation. Given that there are many forms of documentation, it was a bit of a task. I ended up putting together a spreadsheet of the main details so that there is a canonical reference. The first […]

Pi in the Street

I am about to start work on a new project, AI in the Street. I am not sure exactly my role as the kick off meetings are this week. In preparation, I have been playing around with a Raspberry Pi Pico and the aioble library to make really simple tunes on it. Not quite chiptunes […]

Weeknote: AARs and patterns in audio

I’ve been wrapping bits and pieces of the HackRF base app to have some fun. One of the challenges was updating some old code in the AAR that needed a new flag. Next up is to make the gradle build a bit nicer and to add in the name again. I also need to update […]

Weeknote: SDRs, Workshops, and tiny tools

Less weeknote and more occasional update … I celebrated passing my Viva without corrections by putting in a workshop proposal. I heard last night that it was accepted. Now to organise it. While I was working on the proposal and a paper, I wrote a prototype sonification plugin for Gephi. Now that the workshop exists, […]

Weeknotes: It’s raining sensors

Well, prototypes of sensors. I have been playing around with the piezo sensor to measure the pressure on a surface. I have been using a milk bottle as a testing environment to act as a surrogate for a plastic surface to test the code. This goes with the rain gauge, using the HC-SR04 distance sensor. […]

Weeknotes: sensors and so on

A relatively quiet week really. I put in an order for some equipment from PiHut, such as resistors and capacitors along with distance sensors to crack on with looking at audio interventions with the weather such as sonic anemometers and rain gauges. I did some come across a disdrometer which looks very appealing. Just waiting […]

Weeknotes: Listening to the Air Waves

This week I bit the bullet and plugged in some machines. I bought a HackRF One from Martin Lynch and Son with an ANT 500 antenna. I installed hackrf and gnuradio through Homebrew, which is not with out its perils. The gnuradio version (3.10) that is installed does not have the osmocom component so I […]

Weeknotes: Phones and the Environment

A couple of weeks ago, I decided to follow up a query that I had about tracing the way that the Bluetooth signal is constructed through the various layers of software and hardware. My interest is software but this does interface with hardware sensors on the phone. I took the phone apart using screw drivers […]

Weeknote: Planning, microphones, and Arduinos

I have been taking a break over the last few days, so little work to add to the notes. I did play around with an old pot of Bare Conductive paint and using their Arduino library. I do need to get some new paint but the initial idea seemed to work. As a follow up, […]

Weeknotes: Inventory and Thesising

This week featured some time beginning a device inventory at work, something that we have been thinking of for a while. It reminds me that I must complete the image for the server infrastructure, which I fear I may have made too complicated for now. I completed the skeleton of the text analysis skills sessions […]
