Two years since I did not published my IoT slide deck. Here is the new version, now about 345 slides about IoT topics including Sigfox, LoRaWan, Helium and much more. In this edition, you will also find some slide about the digital transformation impact on the society and the environmental impact.
All the slides on this deck can be freely reused for any educational content; Most of them are also used in my different MooC you can fin on my Youtube IoT Channel
The Dragino LPS8, LoRaWAN gateway is a helium ready device you can add to Helium as a Data-Only. It means it does not participate to PoC but earn HNT for transferring traffic.
It’s not a ready-to-go data-only, so you need to register the hotspot in the helium block-chain on your own but it run the gateway-rs software internally.
This device as been designed for Helium, but not only, it can be connected to TTN or another different network, like a private network. The installation with Helium network is not really complicated but you will need to process some command on a terminal and manipulate wallet-cli.
ChirpStack is an open-source LoRaWAN network server that is being use in a coming future with Helium as a replacement of the console. This blog post explains how to install it with the companion solution I’ve built to interact with Helium router.
You heard these terms, increasingly used, that are IoT (Internet of Things) and IIoT (Industrial IoT). Terms that seem so close that we tend to think that they are intimately linked, or even that they address the same thing but in a different context, which for the second would be that of industry. But the technicians, or marketers, are teasing or, because they surf the trends, it tends to generate misleading shortcuts.
You understand, behind my words, that there is no more than a fairly distant cousinship between IoT and IIoT. I will try to explain why and what are the consequences of these differences on the technologies used in each of these areas.
The first versions of Nebra indoor miner came with CM3 (Raspberry Pi Compute Module) embedding eMMC memory. As you may know, Helium has been really I/O intensive, particularly this summer when the blockchain was filling really fast the small amount of storage the CM3 has. As a consequence, all my Nebra indoor miner dead around the same week. Diagnostic seemed to be a storage failure.
The Arduino board MKR1310 is the new revision of the MKR1300 board dedicated to LoRaWan. This board is a SAMD21 Arduino board with a Murata ABZ module based on a STM32 with an SX1276 transceiver. Basically a bit outdated and expensive modem now.
After using this board for some teaching project, it’s a good time to make a feedback about it as many things need to be improved on that board to get benefit of it.
Who doesn’t associate the word IoT with security issues in 2022? Apart from those who do the IoT maybe? Like all emerging domains, shortcuts are easy, because they are poorly understood. I will try to give you some elements on what cannot be denied: security, in the IoT, as in other technologies, is an essential element. I will especially take care to explain to you why it is very essential in IoT, why this subject is poorly understood and also, why many times we talk too much on this subject.
Some time ago, a twitter thread made the community react about the amount of $6600 of communications consumption on the Helium network. This thread was full of approximations in order to present negatively the growth of the Helium network. But it is also an opportunity to take stock of the development of the use of the network. We will see in this article who operates the Helium decentralized network, what are the current data volumes and what are the associated financial metrics.
In short, we cannot talk about Nova Labs’ revenue with respect to direct communication costs because these costs are associated with different third parties offering the packet routing service. We cannot rely on this cost to estimate an associated business volume because there are many indirect costs as I have already specified in my blog post analyzing the running costs of a Helium router/console. Finally, regarding a long period where gamers found a way to earn a few dollars on the back of Nova Labs, involving many ancillary costs, distorted the data for June. You will understand all this in the rest of the article.
