Fun with overclocking old tech!

Fun with overclocking old tech!

If you have a Desktop computer of any kind you'll likely have overclocked it slightly in some way, weather you've done a slight tweak on the CPU, GPU or gone full out on maximizing both. But to be honest, it's quite boring overclocking sometimes now. While my CPU has had a bit of an increase my motherboard isn't designed to overclock, My GPU can overclock a little but wasn't enough of a gain to make it worth the extra heat and power consumption. However I have recently re-installed my Windows XP / 7 Gaming rig (Specifically the Windows 7 Drive) and…

Adventures in LoRaWan & TTN Part 6 - Re-mapping & Improvements

Adventures in LoRaWan & TTN Part 6 - Re-mapping & Improvements

One thing I didn't realise is that Part 5 posted before Part 4. Seeing as I missed Part 4 I thought I'd merge it into a Part 6. Since I got my gateway I've done a lot of mapping and experiment mapping at different SF factors. However a lot of this data has had changes inbetween with improvements made to the gateway by shortning the cable to the antenna, a better U.FL to SMA Connector and more. However as shown below quite a lot of the data is outdated with the range with some measurements being over a month…

Adventures in LoRaWan & TTN Part 5 - Making a sensor!

Well I have a gateway, But currently no devices to use! So let's design a simple sensor. My specification is to make two sensors at a maximum cost of £10 a sensor excluding enclosure. Being outside there's a few things we can't easily sense pressure and humidity since the sensor will be in an enclosed box. I then remembered that a potential project for my degree involved creating a IOT Fridge monitoring system BUT they don't want me to create the hardware as part of the project and to just do the coding for the system excluding the sensor itself.…

The Things Network Great Yarmouth! - Call for members

The Things Network Great Yarmouth! - Call for members

If you're in Great Yarmouth and have an interest in hobby electronics such as the Raspberry Pi, Arduino and other systems then you'll likely be interested in this. The Things Network is a Network designed to allow communities setup a network of gateways that can communicate to nodes or "things" which you can integrate into your projects. Being interested in IoT myself I have setup a gateway from where I live in Gorleston which gets good signal in most of Gorleston, areas in Bradwell & Hopton and peaks as far as Wellington Pier. So what's the community for?…

IMST iC880a LoRaWan Backplane Kit Review

IMST iC880a LoRaWan Backplane Kit Review

As part of my new blog I plan to review most electronics purchases I make. Overview One of the improvements I've been recommended to make is to get a PCB to connect the Pi I'm using to the LoRa Concentrator board. Of which the most popular one seems to be this one by user Gnz on Tindie. ![] Photo by seller GNZ On Tindie. https://www.tindie.com/products/gnz/imst-ic880a-lorawan-backplane-kit/ I ordered it on the 30th of December and it arrived Today. Pretty good going for the fact it was the Christmas Period! The primary idea of this kit is…

Adventures in LoRaWan & TTN - Part 3, Experience So Far

This is a shortish blogpost about my experiences with LoRa and more so LoRaWan and The Things Network and includes more realistic figures so might be a bit of "myth busting". I repeat these are experiences and my views & interpretations. I am not guaranteeing it's accurate. Point 1 - Range is Good, But not Great The range of my LoRa Gateway is good. It gets hundreds of meters further than my wi-fi does. But it's not as good as advertised. You'll see claims of most gateway hardware reaching 10-15KM in perfect conditions. Ideally I wanted my gateway…

Adventures in LoRa & TTN - Part 2, Improving the Gateway!

At the end of the last blogpost I mentioned that the range was FAR off what I should be getting. The whole point of LoRa is that it's long range. So lets try and fix that. This post is a bit like a journal so parts will be rather mixed and maybe out of order. Improving the Node's antenna I'm currently using a LoPy as the node I'm using to ping my gateway, However due to one of the u.fl to sma connectors breaking I had to just use a u.fl connector with a ~ 8.6CM Wire on…

Adventures in LoRa & TTN - Part 1, Building a Gateway!

Originally I was planning on this being a post detailing how to setup a single channel nano gateway for The Things Network, Doing some distance testing etc. However this quickly wasn't the case as I was only able to get approximately a range of Meters before loosing signal. Not great. Range of the Nano Gateway, The furthest was approximately 245 Metres, We should easily be getting over 1KM of range. Step 0 - Funding a proper gateway The first step was to budget and raise the funds for a proper gateway. There are two main options, buy the Official The…
