I made an alarm clock with an esp-32 that has an RTC module for accurate timekeeping, buttons for controlling it, an OLED display for displaying the data, a buzzer for the alarm, and an esp32 for computing.
github.com/Moosimus6/Alarm-Clock-Esp32I designed a simple 3D printed object for 3D printing enthusiasts and beginners that makes choosing an infill pattern easier. This model demonstrates all of the infill patterns usable in Bambu Studio (which are commonly used in other slicers) and displays the names of them in black and white.

I created a diamond ore lamp! It uses a limit switch, 2 (easily swappable) AA batteries, a couple resistors, a blue LED, and some basic hardware to create a really cool effect in a dark room! I provided STEP and Bambu 3mf on Makerworld. Electronics schematic/netlist is on the github!
