Yes, You Can Put IoT on the Blockchain using Python and the ESP8266
https://hackaday.com/2019/03/01/yes-you-can-put-iot-on-the-blockchain-using-python-and-the-esp8266/
I can see some edge cases where it would be useful, for example securely setting the state of some large network of state machines – sort of like a more complex version of this system that controls a single LED via Ethereum smart contract.

It’s more than a little too late for Valentine’s Day this year, but if you start now, you’re sure to be looking good next February. Print something that truly conveys how you feel, through the magic of wireless communication and RGB LEDs (Youtube, French).

The Heat is on with this ESP8266 Controlled Sauna
https://hackaday.com/2019/03/08/the-heat-is-on-with-this-esp8266-controlled-sauna/
We’ll be perfectly honest: sitting inside a heated box sounds just a bit too much like torture for our tastes. But if we did somehow find ourselves in possession of a fancy new sauna, we’d more than likely follow in the footsteps of [Al Betschart] and make the thing controllable with the ESP8266. After all, if you’re going to be cooked alive, you might as well do it on your own terms.

An ESP8266 Sundial For Your Wall
https://hackaday.com/2019/03/20/an-esp8266-sundial-for-your-wall/
This ESP8266 powered “shadow clock” from [Dheera Venkatraman] technically keeps that tradition intact, but only just. His clock doesn’t feature physical hands, but it does use a strip of RGB LEDs to cast multi-colored shadows which serve the same function. With his clock, you don’t even have to try and figure out which hand is the big one, since they’re all the same length. Now that’s what we call progress.

Library Makes ESP Over the Air Updates Easy
https://hackaday.com/2019/03/21/library-makes-esp-over-the-air-updates-easy/
Potentially, one of the great things about having a device connected to the network is that you can update it remotely. However, how do you make that happen? If you use the Arduino setup for the ESP8266 or ESP32, you might try [scottchiefbaker’s] library which promises to make the process easy.

The code started from a different online tutorial but packaged the code up nicely for reuse.

Old Wireless Switches Join The Internet of Things
https://hackaday.com/2019/03/21/old-wireless-switches-join-the-internet-of-things/
Just about any appliance comes in an internet enabled version nowadays. However, even the oldest gear can be switched on and off with an Internet connected power socket. [Bill] is in the process of automating his home, and found some old radio controlled power sockets that badly needed to join the 21st Century. Hacking ensued.
The first set of switches [Bill] came across were easy to work with. Eager to keep things as functional as possible, ESP8266s with Tasmota firmware were wedged into the enclosures. With a bit of circuit sleuthing, [Bill] was able to set up the switches to respond to commands from both the ESP8266 as well as the original push buttons and radio remote.

WiFi Your Door Lock With An ESP

The Internet of Things is upon us, and with that comes a deluge of smart cameras, smart home monitors, and smart home locks. There actually aren’t many smarts in these smart conveniences, and you can easily build your own. That’s what [MakerMan] did with some off-the-shelf parts and just a little bit of code. Now he can open his door with WiFi, and it’s a nice clean build.

Building an Army of ESP32 Air Quality Sensors
https://hackaday.com/2019/04/05/building-an-army-of-esp32-air-quality-sensors/
Judging by what he’s got so far, we think [Samuel Klit] is well on his way. He’s using the ESP32 and some off-the-shelf modular components to create an Internet-connected air quality monitoring station. But he’s not just building one or two of them, he’s building enough so they can be distributed and collect data over a wide area. Who knows, perhaps you’ll be building one next.
[Samuel] is using the CCS811 sensor which can pick up potentially harmful Volatile Organic Compounds (VOCs) and determine carbon dioxide concentrations, as well as a BMP280 sensor to read ambient temperature and atmospheric pressure. There’s also an SD card reader for local data storage, a 1602 LCD display that provides a basic user interface, and the electronics required to support the 18650 Li-Ion batteries which power the unit for up to 12 hours on a charge.

Chatterbox Is an Amazon Echo-Like Device That Protects Your Kids’ Privacy
https://blog.hackster.io/chatterbox-is-an-amazon-echo-like-device-that-protects-your-kids-privacy-dac95d4d3280
Chatterbox will be launching on Kickstarter soon, but is already starting to generate some buzz in the media. It’s a home voice assistant with capabilities similar to the Amazon Echo, but offers two features that you won’t find in a typical voice assistant. The first is that Chatterbox comes as DIY kit that kids can assemble and even program themselves. The second is that it puts privacy first, which means you don’t have to worry about some corporation gathering data about your children.

Tracking Stolen Bikes with Narrowband IoT
https://hackaday.com/2019/05/20/tracking-stolen-bikes-with-narrowband-iot/
For his entry into the 2019 Hackaday Prize, [Marin Vukosav] is working on an ambitious project to create a small GPS tracking device which utilizes Narrowband IoT (NB-IoT) for long range communications. Rather than using a GSM modem which would suck the batteries dry in short order, NB-IoT can theoretically maintain a connection within a 10 to 15 kilometer range while keeping the energy consumption low enough that the tracker could go up to a year before needing to be recharged.
