7-year old CherryG80-3800 self-study and fight for another 10 years

I have used the Cherry3800 for 7 years. To be precise, it is the 3802 version with high keycaps. , I have thought that the keyboard will break one day. 

Somewhat caught off guard.

After a bit of looking around, it turned out that the problem was probably a broken wire end that shorted at least two wires.

I still have a lot of affection for this keyboard. The first mechanical keyboard is also the keyboard I have used for 7 years. I feel good about my own hands-on ability. I once used two broken iphone5s to piece together a repaired 5s as a backup machine. The white panel with the black home button is very individual, and it is as popular as it is for a while, so I think the keyboard can be rescued.

Take him apart, the inside is already dusty.

First of all, this is an old keyboard, and the usb cable is the oldest one without a fool-proof design. After searching on several platforms, I finally bought a spare cable from a certain fish.

Here comes the problem. The original cable is green, red, black, white and gray. The new cable I bought is green, red, black, white and black. Because I don't understand the principle, I was a little confused at the time.

This is the end of the matter, let's do it first, the cable should be universal, I searched the Internet, and there is no tutorial on changing the cable, everyone is so embarrassed?

After thinking about it, we are still in the primary stage of socialism, so we should save it. By the way, record it, it can be used as a reference for other Sao Nianyun 。

Before doing it, in case of accidents, I wrote the colors of the front and back of the thread hole on the paper.

I am really speechless and edited on this mobile phone. The article was about to be finished twice, and half of the article disappeared. After messing with me once, my enthusiasm for writing is gone.

In order to test the three wires of black, white and black, I decided to change the layout, pass through the round hole, and press it directly to the circuit board for testing.

After testing, there is indeed a difference between the two black wires, and the correct wiring method can be found after two tests.

For the new wiring method, welding is more troublesome, and it must be pressed and released without automatically rebounding to weld.

It is best to pull it after soldering. If there is obvious soldering, it is still necessary to fill in a little tin.

Aesthetics are not important, don't short circuit.

Then my keyboard was revived with full blood. Seeing that it is still strong in Afghanistan, it seems that it can fight for another ten years. 。

Ever since, I made a glorious decision to give her to my wife and lie to her that the old keyboard is better. Nonsense, of course I use the newly bought belly keyboard.

There is still a big difference between the Box red switch and the cherry red switch. The feel is completely different, and I am impressed with the domestic shaft.

I recorded a video to see if the follow-up dream could not be uploaded.
