Peripherals Part 1: The first blind box mechanical keyboard that Xiaobai picked up and repaired

Recently, I have become a little obsessed with mechanical keyboards. If it weren't for the keycaps given by Aunt Zhang, I always feel that they can't be used as decorations, and I must make the best use of them.

Aunt Zhang's keycap

However, I found out why the current mechanical keyboards are so expensive. Looking back, the keyboard I bought really didn’t exceed 70 yuan. Now, a random cherry switch costs 200 or 300 yuan, and there are even more expensive ones, which are too inconsistent with my values. , It seems that picking up garbage is a must. I went to Yellow Fish to look for second-hand ones. I didn’t expect that there are piles of blind box keyboards. They don’t guarantee anything, but they are cheap. It seems that picking up garbage is a must.

As a novice, the target keyboard: 1. Bluetooth wired dual-mode; 2. Cherry switch; 3. With light; 4. Cheap. After much effort, I found this:

rk61 dual mode missing keycap

28 yuan free shipping

Product introduction: 1. The label on the back is 20/21; 2. The interface is type-c; 3. Although the keycap is missing, it is still engraved on the side of pbt, the quality is good, and it is removed for use; 4. Cherry tea switch , feels good, in line with expectations; 5, 28 yuan free shipping, cheap, this blind box is worth opening 。

After placing an order and buying it, I opened the blind box and plugged in the data cable directly. When I heard the sound of "ding dong" coming from the speaker, the keyboard light turned on instantly, and I was secretly happy "recognized" . Then immediately use the keyboard software to test the keys, and when I hear the key trigger sound from the speaker, I am secretly happy , only 5 keys were not triggered from the beginning to the end. Then I tried bluetooth again and it was ok. , I feel that one word is "value" 。

It's time to take on the challenge of repairing the 5 key. I disassembled the keyboard to see that the welding pins have not been touched, and then removed the keycap and pressed it hard and found that it can be triggered, but after installing the keycap, I can’t press it all the way, so it can’t be triggered. It seems that the only thing to do is to remove the shaft. (Note: In fact, I have already paid the tuition fee before, it is just a reckless desoldering, but fortunately I am practicing)

Electric heating dual-purpose tin suction device

24 yuan to get it, the brand is a bit expensive

The magic tool is the electric heating dual-purpose tin suction device. I bought it from Guangzhou Huanghua Electronics for 24 yuan. After it is directly heated to the tin, it is directly on the contact feet. After the tin is melted, the tin can be sucked up by pressing it, but the suction is not strong. , One of the tentacles of the lamp was re-welded and then sucked again before the tin was sucked clean. After the shaft is removed, it is the open shaft.

After opening the shaft, it was found that the copper sheet was slightly deformed, which caused the copper sheet to fail to close after the button was pressed. I took the tweezers and tried it with an electric pen. It was connected smoothly, and then I pressed the keyboard back to test. , perfect repair (for Xiaobai secretly happy ). Next, use the pbt coral sea keycaps that you bought on Pinduoduo for 34 yuan.

A new look for the keyboard

Summary: 34 yuan keycap plus 28 yuan keyboard (the keycap is more expensive than the keyboard ), the rk brand bluetooth dual-mode within two years, cherry tea shaft, feels good (experienced by Xiaobai), I don’t know if it’s worth it.
