The video's creator attempts to build a heated seat by repurposing a heating element from a broken hairdryer and an electric oven. However, his initial attempts fail due to improper handling of live wires and using hot glue to mount the heating element. After researching and purchasing a new heating element and a dimmer, he successfully builds a controlled heated seat with a temperature sensor and a relay. Unfortunately, the project ends in an explosion. The creator also discusses the difference between dimmable and non-dimmable LED lights and gives away prizes to his viewers.
1. The person in the video had a broken hairdryer and a wooden/plastic seat.
2. They extracted a heating element from the hairdryer.
3. They hot glued the heating element to the seat.
4. The heating element was connected to a cable that could be plugged into a wall outlet.
5. When the person sat on the seat, they received an electric shock.
6. The seat melted due to the heat from the heating element.
7. The person later used an electric oven heating element.
8. The oven heating element had hidden live wires, making it safer to use.
9. The person connected the oven heating element to a dimmer.
10. The dimmer reduced the power to the heating element.
11. The person tested different types of dimmers.
12. The old dimmer was made of a solid-state switch, specifically a triac.
13. The triac was a bi-directional switch that could be triggered by a current.
14. The person tested the dimmer with different types of lights, including incandescent and LED lights.
15. The person found that dimmable LED lights were designed to be dependent on the AC voltage amplitude.
16. The person built a temperature control system using a microcontroller and a thermal switch.
17. The system was designed to control the temperature of the heating element.
18. The person used a 12-volt wall adapter to drive the coil of the relay.
19. The system was plugged in and the temperature was controlled around the set temperature.
20. The person eventually had an explosion while testing the system.
21. The person gave away scopes and a 3D printer to patrons and viewers.
22. The person was trying to beat another YouTuber, Bobby Duke, in subscriber count.
