    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.

    WiFi Makes The Heart Glow Fonder

    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.
