Wearable Alarm clock.
A wearable watch-like alarm for heavy sleepers like myself. Useful for when you don't want to wake up anybody else nearby and/or you're just a very heavy sleeper.

Chose Parts
Today, I decided on a few of the parts that I will use for this wearable alarm. I chose a blank 1.5 inch wide leather strap as its base because leather is comfortable enough to wear at night and 1.5 inches gives me enough space to mount it with a 3d-printed chassis for the electronics. I decided to power the device using an Esp3-c3 as the microcontroller due to it's size and it's ability to use Wi-Fi to accurately capture time.
The device is going to use one or two vibration motors to actually wake someone up, and the leather strap is going to be kept on using Chicago screws primarily so the device requires a screwdriver to take off, making it impossible to slide off. To deactivate the alarm, one must either shake their arm a certain amount on times, or simply take the device off. The alarm is going to feature a 500mAh LiPo battery, providing enough power for the motors and the esp32 to run for several hours. The battery is also small enough to sit flush within the device's 3d-printed enclosure.
