It takes a while to get to know all the quirks of your 3D printer and filament well. We thought we’d add to the knowledge base and share what we’ve learned about using the eSun 1.75mm PLA filament in Glass Watermelon Red on our Kossel Pro delta style 3D printer.
Grove Plant Care Kit is a smart automated solution for making sure the plant stays alive and well. The electronics monitor 4 different parameters necessary for the plant being happy and healthy: humidity, temperature, UV levels, and soil moisture.
From these variables it creates a watering schedule that will keep the plant at its optimal soil moisture levels. It will provide warnings on its display when UV levels are too high or when temperature is out of bounds between it’s cold and hot set points. With its built in pump and flow sensor, it can water the plant autonomously down to the milliliter.
I created this choker as a project to demonstrate the new MicroNova APA102-2020 LED strips. Photo by Yeti, edited by Batgirl These addressable LEDs are extremely small, less than 1/4 the size of a standard 5050 LED. This project was built … Read more…

Every year a group of my friends have an engineering Secret Santa. The rules are simple: make something cool for under $20 that requires engineering to complete. In years past we’ve seen Google cardboard VR headsets that are 6DOF, match stick rockets, 3D printed fans that explode when used, 3D printed rockets with cardboard launch controls, and a host of other semi dangerous, partially completed projects that are more than a little interesting.

Now that the season of mass gift giving is (temporarily) over, publishing the details on this special gift for a wedding anniversary will not ruin a surprise. So I figured I’d share this personal project that uses simple but smart electronics.

The idea of adorning oneself with glowing bits has been around forever, but instead of smearing ourselves with phosphorescent jellyfish or placing fireflies in ears like some uncivilized cavemen we went for simple LED earrings. We made a build that involves a simple slow-scroll RGB LED and a few reflective bits to bounce that pretty light around for a shiny ear decoration. It is powered by a lightweight coin cell battery integrated into the design eliminating the need for wires. In order to conceal it, we used this brilliant idea by Idunn Goddess to utilize plastic googly eyes that can be found at any dollar store. The benefit of this method is that the battery can be removed and/or replaced once it is worn out or you want a break from being shiny allowing for more than one-time use.
