Let's Talk About Tech!

Background This post may be a bit different from others in the blog, but actually not too different. I enjoy swimming and make an effort to swim at least once a week, but I've always struggled to find suitable swimming goggles. The issue is often water getting inside, causing discomfort from being too tight, becoming foggy, and so on. When you're focused on counting your strokes, it's not practical to stop and adjust your goggles every lap. In the 21st century, there should be a solution to this problem.

Background I'm monitoring the temperature in the datacenter with sensors from ServerCheck . They are reliable and very efficient. They support SNMP and have a comprehensive UI. But, I recently had the need to get the value of one sensor from the CLI. I noticed the company has been renamed to InfraSensing, but the hardware is still the same. Let's see what can be done !

Background I always wanted to print my own PCB. This is so cool to see his own design getting to life. There are a couple of online PCB makers and I'm ready to test one of them ! But how does it work ? What should I do ? How much does it cost ? Where to start ?!?

Background We did a lot of very interesting work so far and we already have a nice working product. However, I have the feeling it is lacking in few aspects. Especially the visibility of its own status and something showing it is working and reporting the data correctly.

Background Yes, I did not resist to share an article on the most discussed topic of the last month ... ChatGPT, the new all terrain tool that address any questions. Instead of writing about something you already know, I let ChatGPT to create this blog post. I asked  questions and I merged the answers below. This is mind blowing ! Let me know in comments what you think about ChatGPT and the generated content. Please Keep in mind that I only layout the text, the entire content is AI-generated.

Background I've received some very positive messages related to my posts about the Wallbox API. This is very rewarding and I would like to thank all the people who are reaching out 🙏🏻. In the comments, I've see people asking for API to restart the unit remotely. Since API only limit is the sky, let's see what can be done.

Background Recently, Rubrik is enforcing the 2FA authentication (Multi Factor Authentication). This is a great security feature that minimizes the risk of unauthorized access to your environment. But how does it work within a script ? There is no way to enter a 2FA code when running a script every day at 2 am for example. The 2FA is enforced starting at CDM v 8.0.2 with a 3 month grace period to allow the customers to adjust their security.

Background Since the lovely box is now created , let's see how we can improve the reporting. ThingSpeak and MATLAB cannot provide me with the relevant reporting - simply because I need time to learn how it works and honestly, I have something else in mind. I have a home automation platform at home called Domoticz, may be I can get something out of it !

Background Now that we have created a device to measure our solar production , it is the perfect timing to improve it. In the previous post, all the electronic components are exposed to the dust and anyone can potentially disconnect the components - intentionally or not. It would be nice to secure everything in a custom made enclosure !

Background With this article, I'm actually starting a new section on my blog : some electronic builds. I have solar panels on my roof since 2009 and this is a real benefit. I mean, not only the environment is happy, my wallet as well. Price of electricity these days are crazy and this is a relief to count on this extra "free" production. The problem is : my inverter is old and provides no means to see how my production looks like during the day. I can only check the production since they have been in production (I have a so called green meter). Plan is to create a cheap mean to measure and log the production.
