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…

Moaning about stuff - Ep 1.5 - Barclays Fixed the Ad?

On the 9th of November I did a blogpost complaining about Barclays Digital Eagle's Advert. The main issue was that they quoted the following in the advert. Look, in there, you need a padlock, when you pay for stuff. If there isn't one, the website could be fake. However I noticed on TV the other day that the advert was slightly altered. I just checked and the original video is now unlisted with a new one published 3 days ago at https://www.youtube.com/watch?v=GbThUL0aLyk And the transcript now is Before you pay, look for a padlock…

Next up on the list of Claw To Do, Rigging it! PSA: Most claws are Rigged in some method in the UK, that's why no matter how well that you line the claw up with the prize.

Moaning about stuff - Ep 1 - Barclays Digital Safety TV Ad

Barclays have been advertising ways to prevent against fraud for a while. Weather you trust them or not is another question with adverts such as don't give certain information over the phone to your "bank" being ironic as when I've had a phone call asking for information, hang up and then phone barclays to report it I then get told it was them. Good start Barclays! Well that's one reason I don't bank with them anymore. However on TV I noticed the new "Supercon" advert. Trying to teach that if a website doesn't have an SSL…

The Pi Claw Update 3.5 - How it works

This blog post will detail how the Pi Claw works and what its currently running on. The Claw Itself Let's start with the claw itself. Originally the machine was a standard small claw machine designed to go more in Pubs, Cinemas etc instead of arcades due to its small size. Along with re-decorating it I took out the original controller board and replaced it with a custom controller which has the following: 2 dual H-Bridges setup to drive the three motors (X,Y & Z). Darlington Transistors to drive the electromagnet in the claw & the light bulbs in the…
