Anet A8 end print alarm box

Anet A8 end print alarm box V1. This box contains the electronics for an end print alarm and fits neatly into a convenient location. It can hold a power switch, a buzzer, four 10mm LEDs, one 5mm LED, and a pushbutton. The design also includes holes for wiring. In my case, I use an ATtiny85, four high-intensity red LEDs, a 12V buzzer, and a blue LED. I trigger the alarm by sending a pulse to the ATtiny using the X-axis sensor when the process ends. When triggered, it beeps five times or until the button is pressed. If engaged and the button is pushed a second time, when triggered again, it will beep continuously until the button is pressed. This simple setup provides an effective way to stay alerted when a print job is finished.
