DigiKey - Chalk it Up [Maker Update] | Maker.io
The video highlights several creative projects and tips for makers. The main project is a sidewalk chalk robot named AP McG, designed by MrDadVs. Unlike traditional gantry-style bots, AP McG is a polar bot, which is compact and mechanically simple, using only two motors. It can draw in a large area and involves converting Cartesian G-Code to Polar G-Code. Another project is a 3D printed cord-knitting machine by Fraens, which is mesmerizing to watch and available for purchase. RootKid's project involves a phone that reads poetry, inspired by public interactions with classic telephones. Additionally, a simple home automation project by DIY Builder opens window blinds using an offline voice recognition board, ensuring privacy. The video also includes tips for wearable electronics from Becky Stern, covering topics like conductive thread and battery selection. Adafruit's new breakout for the TMC 2209 stepper motor driver is highlighted for its excellent documentation and support for CircuitPython and Arduino IDE. Lastly, Digikey's spotlight on Lithium-Ion batteries discusses their benefits and considerations for portable applications.
