ESP8266 Upgrade Gives IKEA LEDs UDP Superpowers
https://hackaday.com/2019/05/27/esp8266-upgrade-gives-ikea-leds-udp-superpowers/
It can be difficult to resist the impulse buy. You see something interesting, the price is right, and even though you know you should do your research first, you end up putting it in your cart anyway. That’s how [Tobias Girstmair] ended up being the not-so proud owner of a LEDBERG RGB LED strip from IKEA, and what eventually pushed him to replace wimpy original controller with an ESP8266.
So what was the problem with the original controller? If you can believe it, it was incapable of producing white light. When IKEA says an LED is multi-color, they apparently mean it’s only multi-color. A quick check of the reviews online seem to indicate that the white version is sold as a different SKU that apparently looks the same externally and has confused more than a few purchasers.

Tiny ESP32 Automotive Gauges Also Chart on Your Phone
https://blog.hackster.io/tiny-esp32-automotive-gauges-also-chart-on-your-phone-bdd2c4392c49
The assembly uses a pair of Heltec Automation ESP32 WiFi boards, which conveniently feature .96” OLED displays. This all-in-one design simplifies hardware quite a bit, and means that besides the actual sensors, little was needed other than a 12V to 5V charging circuit, and a hub to split it between the two.

Control Those Wireless Plug Sockets with This Sonic Screwdriver
https://blog.hackster.io/control-those-wireless-plug-sockets-with-this-sonic-screwdriver-c25fd3509c86
wireless home automation systems have existed for many decades, usually in the form of 433MHz radio-controlled relays. If you have such a system — which are still common today — Robin Hartley has designed a sonic screwdriver for controlling it.

As it was reported in a blog post on Mozilla Hacks, the Web of Things program “Project Things” has outgrown the experimental stage and is now being renamed Mozilla WebThings. It’s Mozilla’s open source implementation of the Web of Things, including the WebThings Gateway and the WebThings Framework; it’s an open platform for controlling and monitoring devices over the web.

Monitor and Capture Output Data of Dot Matrix LCDs with DoMSnif Dot Matrix Sniffer
https://blog.hackster.io/monitor-and-capture-output-data-of-dot-matrix-lcds-with-domsnif-dot-matrix-sniffer-3d6d278447e9
Every engineer has found themselves needing to export data from one device to another at one time or another, and while some equipment offer options to do so, others have removed that capability from their wares.
To get around that issue, Wyatt decided to tap into the oven’s LCD display, take the data, and pipe it over to a phone or laptop where it can be recorded and saved. To that end, he designed the DoMSnif — a Dot Matrix LCD Sniffer Bluetooth adapter, which outputs the data from LCDs to mobile devices.

How To Set up a Website Server at Home for IoT
https://www.digikey.com/en/maker/blogs/2019/how-to-set-up-a-website-server-at-home-for-iot
We will be using a Windows-based machine to run our server. This is because Windows systems are generally easier to work with and code on, so your first step will be to find a Windows system. Luckily for us, running a website server requires very few resources and will run on most systems (if not all). This means you can use a 10-year-old laptop, a small, low-powered computer, or even your everyday PC.

How to use an Azure Sphere starter kit for IoT security
https://www.embedded.com/design/prototyping-and-development/4462280/How-to-use-an-Azure-Sphere-starter-kit-for-IoT-security
Any Internet of Things (IoT) deployment is particularly hard to secure because of three main impetuses: a green-field market which means speed is crucial (the antithesis of a slow and steady security approach); custom solutions which require specialized security considerations across hardware, software and firmware; as well as resources that often get spent in design and development, leaving little left over for security.
However, security is one of the main reasons why end users will be reticent to explore the possibilities of a new IoT application

Do you want to learn how to use ESP32 for P2P remote control of your Modbus-based devices?
Then check out this guide, where you will learn how to do it in a low-powered, cost-optimized and feature-rich way! What are you waiting for?
How to use ESP32 for cost-optimized and low-powered P2P remote control of Modbus-based devices
https://www.nabto.com/modbus-guestblog/
Raspberry Pi’s are not expensive (about € 35,00), but adding a cheap USB-RS485 converter and cables/power supply this easily adds at least another € 15,00- or €50,00 in total
Fortunately, now ultra-cheap, low-power WiFi-modules like the Espressif ESP32 are available which can do the same for less than 1/10th of the hardware cost and power budget, and a Nabto platform adapter is already available for it.
As hardware for our demo, we have chosen an Espressif ESP-WROOM32-DevKitC (available for about € 6,00 from China including shipping, the raw ESP-WROOM-32 module can be purchased for less than € 2.50 in mass-production quantities), furthermore an 3.3V UART to RS485/RS422 converter (we got it for € 3.33 including shipping
