(2)The hinged plastic is completely broken. It’s a structure that requires a lot of force, so I don’t think it’ll be solved by gluing it together
(3)It’s 1.39 million

(5)Isn’t it a wrong design to get all the weight of the head this much;;;

(2)I should fix it so that I can’t adjust the angle I’m going to think about it again tomorrow, so the class will be very neat. LOL. The support rod is divided into three pieces in the floor
(3)ill 1.37 million
(4)Malapalsan mahler83 – July 6
(5)The power consumption was 195W, so I bought a 13V 2A adapter
(6)Domestic safety certification protection circuit
(7)13V 2A 18A Domestic Loader Adapter Power Cord Included
(8)15,000 won

(2)I think you can support it in a cylindrical shape on the lower part of your neck, so it’s designed to connect the two semicircles
(3)It’s 1.39 million
(4)Malapalsan mahler83 – July 8
(5)Two semicircles were made to be tightened together using a threaded insert

(2)I put my head down because my hinge is weak, and I put on a neck cast so that I can blow the wind horizontally
(3)○ 32 will 1.34 million
(4)They’re both fixing what’s broken and abandoned lol

(2)Should I convert it to a smart fan? It’s okay if it’s turned on and off, and if there’s a way to recognize the speed, it’ll be icing on the cake, but I think it’ll be difficult, so make it recognize the voltage of the 7-segment display. lol
(3)It’s 1.39 million
(4)If you just give the PWM signal directly, the speed can be adjusted to a continuous value, not six steps, but the problem is that the PWM is 15 kHz 5V, and the ESP8266 or ESP32 I’m going to use is 33V, so I have to try it to control it even at a low voltage
(5)ill 1.58 million

(2)ESP32 shoots a 33V PWM signal that can be controlled by ESP Home on 13V DC input Directly controlled by the home assistant lol The battery needs to be integrated to operate as a wireless fan, so it’s not good to bypass the original substrate at all and find a way to integrate
(3)”ill 1.27 million”

(2)Obtain the 12V Ground PWM speed control button from the substrate and lower the 5V transform module on the breadboard
(3)It consists of three transistors and connects to ESP32, and it is difficult to use firmware even though it operates input and output as desired You don’t seem to understand the concept of speed fan component
(4)ill 1.23 million
(5)Mt. Malafal mahler83 – July 13
(6)ESP Home firmware is ready
(7)1 When the fan speed is set in HA, the button is automatically pressed several times until the speed is reached
(8)2 If the speed changes by pressing the physical button, it is detected and reflected in the HA

(2)I’ve got all the contacts I need on the motherboard, and the rest of the work is on the breadboard
(3)Transfer to a gaff board and embed the fan into an empty space using a socket for ESP
(4)I don’t think there will be that much space
(5)It’s 1.18 million
(6)Malapalsan mahler83 18 hours
(7)The parts were placed on the perf board and mounted safely in an empty space inside the fanHot glue is the best process
(8)120,000 won for “ill

(2)It’s finished as if it doesn’t look obvious from the outside. I picked up a broken fan and even completed IoT conversion!
(3)Mt. Malafal mahler83-4 hours
(4)It simplifies the trigger that reflects the status of a new firmware, and when changing the speed setting, it does not press the button every second until the corresponding PWM value comes out, but calculates how many times you have to press the button quickly. I’m satisfied!
