Pokemon GO has shown us that people can really go crazy over running around our cities bent on catching imaginary animals. It has also shown us that people are going crazy over chasing down said animals at all hours of the night and not always paying attention to what is going on around them. This is amplified when we are talking about children that are having a blast literally trying to catch them all. Build a safety light that's also a lovely way to show team spirit with this no-solder project!
Vintage radios can be beautiful, but many are beyond repair. Here's a guide to repurposing it as an eerie playback device that uses the original tuner dial, power knob, and speaker and grafts on a Feather ESP8266 Huzzah with Music Maker MP3 FeatherWing that can play creepy sound effects, and trigger a specific song when intrepid guests tune the dial to a specific frequency. Muhuwahahahahahaha!
Arduino is a great starting point for electronics, and with a motor shield it can also be a nice tidy platform for robotics and mechatronics. Here is a design for a full-featured motor shield that will be able to power many simple to medium-complexity projects. Build the kit, and learn how to use it with these detailed instructions.
If you'd like a compact display, with buttons and a joystick - we've got what you're looking for. The Adafruit 128x64 OLED Bonnet for Raspberry Pi is the big sister to our mini PiOLED add-on. This version has 128x64 pixels (instead of 128x32) and a much larger screen besides. With the OLED display in the center, we had some space on either side so we added a 5-way joystick and two pushbuttons. Great for when you want to have a control interface for your project.
