This week we have a couple of hardware projects at the front of our queue, so you might want to switch your soldering iron on to heat up now.
- First, we have a Web-Radio project which Jean-Pierre Cocatrix has forked from Piotr Sperka’s original. JP’s version has a separate write-up on Hackaday IO, too.
- Alex posted a 07/12 dev board on Hackaday IO almost exactly a year ago. The nice thing is that he’s carried on updating it and his latest, 2.3 revision is now available. This board has a LiPo charge controller built-in, for battery powered applications.
- Andreas Spiess has a very nice tutorial of how to use the RTC memory for storage of data between deep-sleep resets. Watch the linked YouTube video for the explanation.
Finally, here’s a teaser from a high-school in Spain where they are using cascaded ESP8266’es (rather than mesh networking). I class it as a teaser because there’s an explanation and a video (in Spanish), but no code or example configs that I can see (updates welcome in the comments section, below).
