The video is a humorous exploration of the author's height and how it affects his daily life, specifically with regards to taking pictures. The author, who is short, complains about the lack of legroom in public transportation and how his feet often hang off the end of beds. He also laments the challenge of taking group photos due to his height.
The author then proceeds to create a device using an Arduino, a wireless flash trigger, and a TENS unit. His idea is to use the TENS unit to electrocute the legs of everyone else in the photo, making it easier for him to take pictures at eye level.
The author tests the device on himself, and after some initial shocks, he determines that the best muscle group to electrocute is below the buttocks and above the leg armpit. This triggers a strong contraction in the muscle, causing the person to fall to the ground.
The author demonstrates the device on three friends, who react with varying degrees of shock and amusement. The video concludes with the author declaring himself the tallest person in the room.
1. The speaker is discussing the challenges of being short and how it affects their ability to take pictures, as they have to adjust their position to match the other people in the photo.
2. The speaker has considered solutions such as using a scissor lift or robotic arms to compensate for their lack of legroom, but admits that they don't know how to build these things.
3. The speaker then jokes about a solution to the problem - electrically shortening others' legs.
4. The speaker introduces the concept of a tens unit, which uses high-frequency electricity to stimulate muscle groups.
5. The speaker explains how they plan to use a wireless flash trigger to detect when the shutter button on a camera is pressed, and then trigger a tens unit to electrically stimulate someone's legs.
6. The speaker details the build process of the device, including 3D modeling and printing a box to house the electronics, loading the correct code onto an Arduino, and connecting various electronic components.
7. The speaker mentions that they have successfully built three units, which can fire simultaneously within a tenth of a second of the camera's shutter button being pressed.
8. The speaker discusses the placement of the tens unit pads on the legs, and mentions testing on different muscle groups to find the most effective one for their purposes.
9. The speaker describes the experience of being shocked by the tens unit and their reactions to the pain.
10. The speaker shares their enjoyment of the science behind the project and their joy in being the tallest person in the room.
11. The speaker mentions that the video was sponsored by Honey, a free browser extension that searches the internet for the best promo codes when shopping online.
12. The speaker encourages viewers to use Honey to save money on their online purchases.
