This tutorial I just published on Instructables details the construction of an ESP8266 and Arduino powered soil moisture meter using a NodeMCU board, Adafruit IO, and IFTTT. The project is part of a larger free Solar Class with more solar panel projects and some backyard projects, too.
Learn to solder at our next intro class on November 12th. In this hands-on workshop, you’ll learn how to use a soldering iron safely and effectively, and get plenty of practice with both soldering and desoldering techniques. We’ll be soldering up some Game of Life kits – LED tiles that generate nifty animations. No previous experience is required, making this introductory workshop a great choice for anyone who’s curious about getting started with hardware tinkering! All materials will be provided.
Want to get certified to use our laser cutter? Of course you do! Our next laser cutting class is on Oct 14.
In this three hour class, we’ll walk through all the steps from idea to pressing the “go” button on the laser. We’ll cover safety, basic file preparation, and learn how to do a burninate test to find out if a material is laserable. After the three hours, you’ll have made a plaque for your door, a keychain, a simple box or something slightly ambitious. (There is lab time for laser cutting, questions and answers, and working with Inkscape, Illustrator, Corel Draw, etc.)
