I decided a few months ago to cut the cord and get rid of my Sky TV subscription. Between a combination of purchasing and returning a Saorview Connect box, and trying out various front ends, here’s the end-result, and I’m delighted with it.

I didn’t think there’d be another car audio post so soon, but about 8KG of noise reduction matting arrived in the post, so I though I’d give it a go. This is not something that is directly related to the sound system in the car, but more to do with reducing road noise so the music can be heard more clearly whilst driving.

Here’s Part Two in a series of articles where I upgrade my car’s audio system. See previous article here. This time we’re going to take a look at upgrading the 165mm speakers in the four doors, and adding bass blockers to the 89mm speakers added in the last article.

I got a new (to me) car and, while I love it, the sound system is pretty crap. So I decided to investigate what could be done to improve it. Research showed me that the Mazda 6 has two options when it comes to the default sound system, one is a standard 4-speaker setup, and the other is an 11-speaker Bose sound sytem.

I’ve been toying a lot recently with LoRaWAN networking, even going so far as to build a full gateway and mounting it on my house. As an alternative, I ordered some GSM shields from AliExpress which connect into your existing GSM providers network. It saves building a gateway, although the running costs will probably be higher.

A few months back I built a full LoRaWAN gateway node for The Things network, and now I’m finally getting around to writing it up. I’d recommend this project to anyone interested in IOT, as it’s very edudational, and you’ll be helping expand the LoRaWAN network coverage in your area. In this build, I use a Raspberry Pi, a RAK831 8-channel gateway and an adapter board (also from RAK) that allows the RAK board to be mounted easily on the Pi.

I’ve been using an ultrasonic sensor in my Kerosene Tank (Home Heating Oil) for a while now, but was not happy with the stability of the readings. Especially on relatively warm days, as the fumes in the tank seemed to confuse the readings. So I decided to try a different type of sensor, in the form of a 4-20mA Liquid Level sensor. This article shows the setup and compares to the ultrasonic sensor.

Here’s a new revisison of a type of device I’ve been playing with for a long while, a DSLR Timeplapse Controller. This one is ESP8266 based, and creates a hotspot to allow you to set up the timelapse parameters, and easily run a timelapse from your smartphone.

Here’s a few 3D models of the time-lapse rail I’ve been working on. I’ve put a good bit of time into the models, as I feel it’s a good way of showing how the construction is done for the various parts of the rail. The last model is of the complete rail. I still have a few parts to add, like the Tripod Head and WiFi Antenna, but they do demonstrate the construction nicely.
See the Github repo for models, electronics designs, laser cutting info, software, etc. I’m adding more and more to that as I get the time. In the near future there should be enough info for people to easily build their own rails. And there are other posts in this blog showing more. Be sure to check them out.

So I ordered three sets of PCBs from OSH Park (USA) and Seeed Studios (China). They were ordered very close to each other. Here’s a breakdown on how quick they got here, and how much they cost. Interestingly, they all shipped the same day (June 5th).
