In this tutorial, we will see how to make an image clustering based AI with the Seeed Wio Terminal and the Grove AI camera. There are different tutorial on this, the main source of this tutorial is located here. The purpose of this is to have a step by-step approach for my student to realize this in a limited time they have.
This is based on SeeedStudio K1100 development kit.
Recently, on Linkedin, I reacted on a publication that is looking like this one. I’m used to react on LPWAN publication when they are comparing technologies as this one. Comparing apples with eggs and usually meaningless. This one was particularly interesting me because, most of the content is non-sense and scientifically subject to discussion. I’ll detail it in this blog post.
It’s really interesting the way it has been made and also the way the author publish it, react on it on Linkedin and what objectif is serves : capture people in a world where the truth is adapted to make you think only one of the technologies serves all the possible use-cases and all the others are the worst existing. The purpose is to sell you some books and services. This is really looking like the way flat hearth believers, radio waves danger believers and other groups do to find adepts and to sell goods to them. It’s really funny to see and discuss.
As the Author of the original document above considers his slide as “art” you can’t use, copy, cut (even if he published it online on social network) I have made my own one and simplify it to not entering in the expecting promotion this guy is looking for and to troll on the social networks. The curve you see are the exact copy of the original one. These data seems to come from a university work and are needed to be debunked. I just not mention the highlighted technologies other than Sigfox and LoRaWan because they are the one the slide tries to discredit and we will see how that’s wrong.
I do not identify the original author of that “artistic work” because I consider the scientific aspect of that “work” so bad that it discredit too much this person, its student and the associated university, that I don’t want to discredit these people directly. As I did on Linked-in but the author has immediately identify itself to start its promotion.
As I did not had access to the full study, sources of these graph, I can’t tell if the initial work quality that as been done is bad or if the context of the experience is explained. May be the original document explains different conclusions, so I’ll try to not judge too much the original work that has been done. I’ll judge what the author of the slide gave to us, as a single slide with pseudo-scientific information and a fake conclusion. Apparently, if you are ready to pay for the book / register… , you can get more details, thing I do not want to do to feed the troll.
In some of my previous post, I did talk on Kineis IoT satellite solution. The competition is that area is large and one of the other player is Astrocast. I really thanks them for getting me in the program to explore this technology (and I apology to have been a bit long to start using it).
Astrocast is a Swiss company launching nanosatellites to currently provide Europe, Asia, Africa coverage for IoT. It uses L-Band (1-2 GHz) radio. The transmission period will be 15 minutes once the constellation will be fully deployed. The current constellation is 10 satellites for a target of 100 satellites by 2025.
I’m currently building a tool to monitor and alarm a fleet of hotspots (stay tuned) and it currently uses the Helium API (api.helium.io). But helium APIs are a bit overloaded and not made to support high rate querying from each of the application any member of the community is developing. So I’ve been decided to make my own instance of ETL and API for my own purpose. This is the experience I’ll describe in this blog post:
The Kineis IoT solution is an IoT network based on satellite’s communications. Thank to it, a device can communicate from any point of Earth with a single technology. Kineis is using an existing fleet of Argos satellites launched during the last 40 years and is already commercially available. This fleet will grow fast in the next two years to offer a communication window up to 4 times per hour.
In this blog post, I’m going to detail my first experience with Kineis for sending frames through the satellites of the fleet. I’ve been using a KIM Arduino Devkit. The on-boarding is quite fast, let’s see this!
Even if you think it is the first time you heard about Kineis, you are basically wrong in some ways ! This company is a recent “Startup”, existing since June 2019 but for real, they are managing an IoT offer based on top the famous and quite experienced Argos system, started in 1978 and now operating more the 22.000 devices running application like animal tracking, ocean safety and many scientific programs. The service is running over the 8 satellites currently in orbit, making Kineis the most advanced satellite IoT solution commercially available as of today.
Thanks to the polar orbit of the satellites, the whole earth is covered, no white zone, no blind spots from pole to pole, ocean to desert, device are communicating from everywhere, autonomously.
This blog post is the first of a series made with the help of Kineis to introduce you the technology and my experience with it. As usual, there is no sponsoring for these blog posts but a close work with Kineis as the offer is only open to business companies currently.
Companies like Exotic Systems, Arribada or Advanced Tracking, have already started to make products using Kineis network for asset tracking applications mainly.
After reviewing the Rak Wireless miner in a previous blog post, after receiving my own Nebra miner, I’ll give a review of it.
The Nebra miner is one of the different Helium miner machine. It is at first a LongFi (LoRaWan) gateway. It includes a software to run it over a blockchain to create a global IoT network. you can get more details on what is helium in the linked blog post.
This review is on a Nebra batch #1, it is possible that some of the given information will not be valid in a couple of weeks when the batch #2, #3 … will be delivered. No need to precise it but this is an end-user review. I’ve ordered and paid my miner. I’ve no link with Nebra.
