The new student student party was very interested in doing things for himself from a young age. Most of the college entrance examinations were electrical majors. However, they were not admitted. They were eventually transferred to a pure science major in geography. The road went dark until I read the graduate student in geography... The teacher is a research fanatic and there aren’t many projects, so I didn’t have any research assistants to send to me. I rely on school scholarships and my home to spend some money. Miserable) The first thing to buy is to look at the price. Concerned about Zhang Aunt has been for some time, look at others postings seems to be very cool, recently just want to change the keyboard, individuals are not accustomed to using 87-key keyboard, because their notebook is full keyboard, used to enter the number with a small keyboard The day, so prepare to change a 104 key, and the other black shaft with a long time also want to change the axis to try, female tickets also just changed the job, I asked her if I put the keyboard transformation she would not take it, she Without saying anything, I promised, and I have the following long process of transformation. In general, it was a big shake-up. I wanted to write it separately, but because I always forget to take photos when I work, so the process records are not many, most of them are already done, so I write it together. Now, share with the governors.
First, raw materialsIn the second half of last year, the Pennefax V500 black shaft bought in Dog East spent 199 oceans. It was his first mechanical keyboard. At the time, he did not know much about mechanical keyboards, plus he was mainly to play games, and to Rapier. This brand does have some good feelings, and it is integrated into this one.
I usually play mainly DNF, 2D fighting games, most of the operation is done with a keyboard, Pennefather's black shaft V500 is very straightforward and very agile when playing the game, there is no feeling of dragging, but usually typing Somewhat painful, writing a word document is a bit tired. The female ticket wanted to get to the office, so the tea shaft with a sense of passage and no noisy became the first choice for transformation.
As the content of the renovation is very large, because it is usually busy, all the work is almost completed on the weekend. This is the first time I have touched this kind of keyboard. Almost all the work is done for the first time. In addition to the use of electric iron wire, all the work is done by me alone. Most of them are in the bedroom. Completed, because someone moved out and left a desk. I used it as a workbench. Besides, the next-grader also graduated and moved away. Their room is connected to us. We can go in. So this is very The tasteful work was done next door. Here I will first talk about the main tools and materials used, and I will put some drawings of the materials below. The main materials are: used cherry shaft switch, 3mm light emitting diodes, various colors of paint and matt gloss oil, different thickness of sandpaper, gas masks, dyes, small glass bottles, electric iron suits, tweezers, pliers and screwdrivers. Some of the tools are already there, but most of them are for the new purchase of this keyboard. It also costs a lot of money and is enough to buy a new keyboard. But the female ticket is more concerned with this is I do it by hand, she called me this act: the romance of engineering men.
Second, change the shaftPyramid's keyboard uses the Pyramid axis, because it is a novice, but also can not understand the difference with other manufacturers and axis. Mi 5's macro photography is a weak chicken, but the details of the axis are not clear, so no photos are left. The new shaft is 99 new 40 cherry and 10 cherry green shafts bought at Xianyu. Only the cherry shaft has been replaced in key areas. Some people said that there is a paragraph of the axis of the body do not buy second-hand, because there may be no sense of passage, but later saw the seller said to be removed from the new cherry 3800, including, and as long as 1.6, so Contact the seller to buy 50, the following is the photo:
Positive, looks very new, with a cherry logo.
On the side, you can see two plastic feet below the green shaft. This should be the legendary five-footed shaft.
Remove the green shaft and take a small piece of wire inside. The sensation of the passage of the green axis is still there.
This is the axis of the tea. There is a small diode inside. The sense of the passage of the tea axis is not as strong as the green axis, but it is also there, and it is distinct from the black axis.
The demolition is almost exhausted, unlike ants...
The next step is to remove the axis from the original keyboard. The steps are very simple: 1. Remove the keycap, 2. Screw the front and back sides, 3. Unplug the main control, 4. Use the electric iron and the suction solderer behind the PCB board. Remove the solder, 5. Take off the shaft.
Due to the height of the keyboard, the wrists will be very tired when typing, so I would like to buy a wooden hand care, free custom lettering!
Changed the keycap before, the original keycap is opaque ABS material (the old version is said to be light, although there is no light), with a long time to fight the oil is very serious, so in the letter area for the orange PBT translucent key The cap (no light to be translucent) has to be matched with the overall tone.
Before changing the keycap once, the middle letter area changed the orange PBT keycap.
There are two self-illuminated keys in the upper right corner, which are the win lock key and game mode. In addition this keyboard also has an independent volume control key, very easy to use!
This is the keyboard light that V500 brings, it is game mode and WIN lock key respectively.
Remove all the axes and you can see that all the big keys use the balance bar design. Especially with this space, the rebound feel is quite good. The evaluation of this space on the Internet is also very good. But the tragedy is that the style and size of the balance bar is designed by Pythago, and it is incompatible with the structure of the balance bar in the market. Therefore if you want to change the keycap, you can't change the big area, unless you customize it. Big key cap.
Unplugging all the keycaps, you can see that the bigkeys are designed with a balance bar and that springback is quite good.
This is a comparison of a chrysanthemum with a normal keycap. It can be seen that the structure inside is completely different.
Even more surprising is the capital lock key, the original keycap chrysanthemum is not in the middle of the position, the normal keycap is mounted on the left will come out about two millimeters, dizzy ... looks like this chrysanthemum non-center keycap , but it's expensive to buy separately.
Remove the positive and negative screws and unplug the master.
Keyboard master with on-board memory.
Then you can take out the steel plate and the PCB together.
Turned the steel plate, the black PCB board is exposed, visible shaft welding is very strong, the solder is also very full, but behind the dirty Oh, all kinds of unknown liquid traces ...
Then it was the turn of the electric iron kit. The yellow 660 electric iron was not paid much attention when it was bought. Hearing people said that the yellow flower was very good and could be used. I am not unfamiliar with electric irons. When I was in junior high school, I liked to own some circuits and the like. Dad bought me a set of electric irons. I haven't touched this stuff for nearly a decade...
The soldering iron is assembled and ready to dry!
This is the first time that I used this device. I was not used to it at first, and many of them did not suck cleanly. Then I slowly got better. The following figure is an accidental use of electric iron, burned a shaft foot...
After the solder is completely cleared, the axis switch can be taken out. The following figure is probably to see the specific state of the original axis switch of the clear keyboard, and each axis has the sign of Pennefather. As some of the solder pins on the shaft had not been cleaned, they were afraid of breaking the PCB board with a miracle. Then they took several shaft feet and took the shaft down. For example, this first shaft was taken down. Directly to the light-emitting diode also cut.
Removed two rows, exhausted...
After removing all shafts, the plate and PCB can be separated. 
After that, the axle body to be changed is reinstalled, and a mixed-axis keyboard is laid out. Here, I replaced the letter area with a tea axis. Several commonly used keys such as ESC, spaces, and arrow keys are replaced with the green axis. Others are not normally used with the black axis on the original keyboard. Let the female ticket appreciate the differences in the feel between the different axes so that when she chooses the keyboard later, she has a reference. Originally wanted to get a few red axes, but the shop did not sell it, and I didn't want to go for it once again, so I gave up.
The above is the whole process of keyboard replacement, of course, this is only the first step. Next is the most painful shell paint, which is the place I am most dissatisfied with.
Third, the shell spray paintWhen I originally bought the keyboard, I didn't even think about DIY, and the black shell with the orange steel plate looked like a coquettish (Meng Sao). I didn't realize that the black shell was really not a good keycap when I started the renovation. , especially I want to make a rainbow keycap. I myself prefer to spray the shell into orange, because the more with the steel plate, but the female ticket is more like pink, no way, all the preference for female tickets is slightly preferred!
The spray paint first polished the keyboard shell, because the keyboard and keycap shell had a black paint on it. I first tested it with a few big keys, because I originally planned to spray these big keycaps too. . First grind it with 360-grit sandpaper, rub it off, and polish it with 2000-grit sandpaper.
This is a comparison between before and after grinding. It can be seen that the paint is being polished, but the font is still there. I did not expect this type of printing to be so solid... I felt that the surface plastic was ground down, but there was no problem with the font.
Next is the shell polished, the area is too much is really tired, with a lot of sandpaper, the back of the words did not print so strong, a lot of wear off.
Remove the feet, these feet are a bit small, slippery ability worrying.
After all grinding, a family portrait.
Rinse with water and add detergent.
Put it on the window sill for a night, but don't drop it one or two.
One night passed and all were dried. Chrysanthemums were placed on the outside to prevent water inside.
Spray paint, a few dollars a bottle of three and since the paint, the United States and cheap ... mainly I do not really understand what specific paint is better, there is no more professional tools, take this to test it.
First spray a white primer, it is said that suction will be more accidents, pig nose go!
Try it with a keycap first, it's not bad.
Upper shell! There are tutorials on the Internet saying that it is a small spray and multiple sprays, but... How often do you spray it once?
Afterwards, it was sprayed once. In some places, there was a lot of spray and there were drops.
Family portrait, dry one night and spray the second floor tomorrow.
Afterwards, the pink spray paint was sprayed once again... I didn't know why, when I sprayed, I couldn't control it all at once. I sprayed it all over once... The uneven place in the middle of the shell was the time when the front was dry and the back was The lacquer on the small box, which is the support, sticks to the shell, and when it is finally smashed, it becomes pitted.
Before reading a post and seeing that there was a sticker on the keyboard, she looked at the woman's ticket. She strongly demanded that this sticker be also a sticker on a treasure. It was originally used as a tattoo sticker. There should be no problem with the keyboard.
Or conventional, first use the keycap test, found that it can be oh, very cute, the sticker should be affixed before the Yaguang Varnish, and all the bubbles inside out to go out.
Forgot to explain before, the keyboard was sprayed with pink paint on the sides and the back of the keyboard. I chose orange on the front, or because of the color of the steel plate. Because of the narrow border design, there are not many places that can be affixed to the stickers. Posted some.
The back and side are the most affixed, the female ticket is very dreamy? Anyway, I do not have the aesthetic. After drying it, it is dried and finally sprayed with a layer of matte oil. It can be clearly seen that the texture is different from the simple paint layer.
Spraying the paint on the shell here is also a good idea. Let it go and let it dry... See the little bottle on the table, it's stained paint. The next section is my most satisfying keycap invasion. Dye it!
Fourth, the key cap infectionIn fact, the key cap infection I felt at the beginning was the most difficult job, especially the color accuracy and infection time. However, after the actual operation, it is not very difficult to find out, especially if your request for color is not very accurate, as long as you can match out a beautiful keycap, you do not have to strictly follow the preset color, the most important It is necessary to grasp the time of infestation. The key caps of the same color should be put together and boiled at the same time. Do not talk nonsense, come to the map!
As mentioned before, the light of the keyboard is downlighted. This will result in a very painful result. The letter of the general PBT translucent keycap is in the upper part of the keycap. It will be very difficult to see through the letters of the upper lamp. The bright, dark ones are not dark, as shown in the figure below.
Although I personally like things with light pollution, but this is very disgusting with the surrounding light is still quite nasty, I feel very cottage, the more subtle light is my favorite, such as Logitech's G810, only the middle of the letter Transparent, no spill around. Of course, Logitech's axis of the keyboard is a special design, DIY would not even think about it, there are not many side carved light, and the first is expensive, and the second is the color is basically black. In the end, he chose a white, opaque PBT cap that wasn't light enough to look at. The seller's show wasn't completely opaque. The light could still pass through the keycap. In that case, it would be so.
I chose a set of 104-key OEM high-side white PBT keycaps. This set of keycaps also sent several unengraved keycaps to replace some unique keys, such as the volume key of my keyboard. .
In addition, at that time, in order to get rid of the postage of the electric iron suit, I additionally purchased a custom ESC keycap and two keycaps with a small transparent window on the side to be used to hold the keys in win lock and game mode.
Using the light source of the student's millet max flash, the color of the two-color temperature lamp is yellow. The keycap itself is white, and there is a small transparent window in the middle of the side.
Before dyeing, we must first determine the color of the keycap. I have found a blank keycap on the Internet, ps is the keymap of my keyboard, and then it is colored. The following is the effect diagram, the main keyboard area is the gradient color, the function area and the direction keys are for each color in the front to be dyed, F area is the color of red and white (the original design is orange and white, but later I don't think orange looks good.)
Before dyeing, still old routines, wash, dry.
About dyes, they were found on a certain treasure. They purchased seven colors: pink, red, orange, yellow, green, blue and purple. They can be used as the main colors of the above columns, and the intermediate color can be changed. Use two adjacent color tones.
On the pot, before buying a small pot, originally wanted to get up in the morning to cook the instant noodles in the morning, the result ... can not get up well, and finally led to buy back once never used. Add a small amount of water, about seven or eight centimeters deep, I have no concrete concept for this, anyway, to drown the keycap (this is not nonsense).
According to the keycap from left to right, first dye the leftmost pink, here I use the pink dye, a little enough.
Dark food (mist)? Also need to have a colander, easy to remove all the key caps at one time, I did not buy big, this feeling is a bit small.
Using a small board to do the timing, said the key to dyeing is the amount of pigment and the time of cooking.
Use a few extra keycaps as a benchmark for staining. Record the time. The figure below is for one minute.
After two minutes...
After five minutes... Didn't say that it took a minute or two to dye? Why did I get so satisfied with this color for so long?
After completing the benchmark experiment, I tossed all the keycaps in the first row and boiled them. According to reason, there is still a pink line behind, but I am afraid that I couldn't fit in the pot and dyed it one by one. The following figure shows the first column dyeing five. The effect after minutes.
After cooking, pour the water, wash the pan and spoon, add the dye again, use the new keycap to do the experiment, and then dye the second column. I used the colors that I had originally, such as pink, red and orange. As for the color between red and orange, after finishing the orange keycap, add some water and add a little red pigment to continue the experiment. If you don't think it is enough, continue to add it. Remember not to add too much. If the solution in the pot is too strong and the stain is very fast, you don't have much spare time to determine the color depth you want.
There are always a lot of such white scratches on the red keycap. I don't know what's going on. Other color key caps are also available, but not so exaggerated. In addition to the second column of red, the F red key cap also has this kind of scratch. Is it the relationship of color?
Slowly, dye it halfway...
The shift key on the right side I designed is a gradient color, left purple and pink, but do not know how the actual operation, when the stained purple tried it, only put one end into the cook, the final effect is not bad, behind the space gradient It is also done.
All the colors were dyed. The figure below shows the key caps used for the benchmark test. There are beautiful woods.
All the keycaps have been dyed from noon to 5:00 pm and have not been idle for a moment. Keep stirring to prevent uneven dyeing caused by the bottom of the sink. My unicorn arm feels tired. Chrysanthemum came out to dry overnight.
One night passed and could not wait to pick it up and set it up! I feel good, there is a crystal clear feeling there is wood! So I said this keycap dyeing is my best thing this time. The picture on the keyboard will be sent at the end!
The above is the whole process of key cap dyeing, personal feeling is not very difficult, as long as you can grasp the cooking time, first set the main color, if the transitional color if the color requirements are not very high, generally adjacent two colors It doesn't matter if you combine them. The main thing is not to add too much, not too strong, such as my orange left of the space bar, if the solution is very light, the color level will not be so abrupt, just like the right of the green, but the orange is already very strong, I Put that part of the keycap just in the pot, did not directly give me a big orange in a minute ... all kinds of unexpected and no! !
Fifth, plus lightsWith regard to the keyboard plus lights, the process actually started at about the same time as the change of the keycaps, but for various reasons, the process went through various twists and turns... so I put it to the end. Similarly, the result of this additional light is not very satisfactory... Hey, you read it and you understand it (because I didn’t know if Aunt Zhang had stipulated the length of each article, I’ve written it here. Because about 80 pictures have already been added... Well, how much is it written?).
The first thing to note is that there is no light on this keyboard PCB, so you have to go flying. In addition, the keyboard does not support mixed pressure, so only diodes with the same voltage can be used. At first, I bought a very colorful lamp, thinking about connecting two different voltage lamps, each group of different resistance, later found it difficult ...
The store's introduction saw that the red, yellow, and green colors in this store are a voltage of 2.0~2.2V, but why does the company only have red light after connecting, and yellow and green simply cannot be seen? In addition, my varistor bought one, no extra resistance...
So I reluctantly took a long time to completely remove the lamp, and bought another one hundred white lights in another store, thinking that because it is rainbow keycaps, white lights can map out different colors. But... Why did I shoot 3mm endless lights all come with edges? ! I had to cut the edges one by one again
The back fly line... I didn't even see it myself. When flying lines must pay attention, it is best to fly a battery test will not be bright, so that timely detection and modification of the problem, if it is too much trouble, at least to fly to test a row, or later a problem The process of re-cultivation can be cumbersome. The end of the line is in the top right corner, which is the position of the front win lock button, where there is even a master.
This is the final result. It is all bright, but there are several lamps whose brightness is very uneven. It would be nice to put in a new lamp... I swear I won't buy it again in this store...
Put on the PBC plate and start welding the shaft. However, at this time, the iron of Lao Tzu was broken! ! ! I originally wanted to remove the old iron head and replace it with a new one. I didn't think the screw was too tight to be screwed down. So I thought about it, used it, and then... I found it was not powered up... I didn't see where it was broken, all of it was good, that is, no electricity... so I bought a new one...
The legendary artifact, Huanghua 907 electric iron, comes with a cutter head, adjustable temperature ...
Nothing to say, weld it. But when it comes to this, I have to Amway to buy a roll of solder later, the following goods: Japanese Yamazaki solder wire. In fact, I don't really understand the structure of these solders. I only know that the less lead there is, the brighter the effect is, and the higher the melting point is, the more I used to look at the solder, and it looks like this is very high-end. Look like? When I bought it back, I didn't expect it to be awkward. It was very friendly to my newcomer, which welding was very easy. Especially for the new component connection point, it was almost second welding. This solder also has a characteristic, its curing speed is slightly slower, it may take a second or two time, double-edged sword is, if not connected at the time, you can also slightly adjust before solidification, but it may also be thought that already welded The place where you live will be separated because it is not fixed.
With the newly purchased soldering iron, all shafts were soldered. Each of the solder joints is very, very full and round, and once it passes, the solder is easily solidified on the solder pads, and there is no point of solder joints. Is this due to solder or soldering iron?
Regardless of the lamp's line, the main control plugs in, connects to the computer, and is perfectly lit. Each button also works properly and grows in one breath. At least it has no problem as the main function of a keyboard (the key bit test image does not pass up).
Then, connect the positive and negative wires of the flying lead to the positive and negative contacts above the master. The two contacts are very small, the positive electrode is connected at once, and the negative electrode is not even connected to life... I scraped it a few times and finally took more than half an hour to finally connect...
This is a photo taken without a resistor. It is obvious that there are several problems. The first is that the closer the brightness is to the power source, the higher the brightness, and the darker the farther away, which may be because the resistance increases with the length of the wire. Secondly, there are several lamps whose brightness is obviously darker. In addition, according to the normal requirements, the voltage of USB is 5V. The diode voltage of this white light is 3.0~3.2V, and it is necessary to add resistance to reduce the voltage, otherwise the lamp may burn out. . I originally bought a variable resistor, but it turned out to be no effect... was it broken? In addition, it was said that adding three 1N4007 (doesn't seem to be a trick, looks like a diode) can be reduced blood pressure, and we plan to buy a few resistances in a few days and then try again. Anyway, this main work has already been done.
Next is the exciting keycap! This set of side-cut rainbow keycaps is really like it (some keycaps are in the wrong place, don't care about these details). In fact, the white shell is more suitable for rainbow keycaps. What do you think? Come to a few comprehensive pictures!
positive
The bottom spacebar is set up. That's because the internal structure hasn't changed. Afterwards, it's all right after the transformation. There are FN and Alt on the right.
top.
On the back, there are many impressions, because the paint on the surface is soft.
Side, green and purple two row keycap height is the same, because the original design of the location is not here, due to the keyboard on the upper right corner of a few more buttons, so the original R4 area of ​​the green keycap squeezed into the R3 area ...
Turning on the lights is the effect... The lights below are a little dark, and the first row is a little too bright, if all the brightness of the second row is just fine. In fact, I also thought that if the lights of each row were connected in parallel and then connected in parallel to the main line at the same time, could the voltage of each row of lamps be kept consistent with the resistance on the line? However... I have no more energy left to engage in these...
It took more than two weeks before and after the remodeling work of the keyboard, because the usual workday was very busy and they all stayed in the office. After that, they returned at 9:00 and had time to work on the weekend. In the middle, they took a lot of detours and spent a lot of time. I wasted money and wasted a lot of energy to do this, but every time I sent a photo of the progress to a woman's ticket, she would give me encouragement and show her a pair of wow, awesome, and the like. I feel very fulfilled. After all, she likes what I do personally. Spending so much money is enough to buy a new one, but she doesn't necessarily like to buy it. In addition, this process is also full of fun. When I put all the keycaps in order, the moment I plug in the lights, my heart is filled with joy and a sense of accomplishment. It's the biggest pleasure of hands-on!
In addition, there are a lot of deficiencies in this work, and I mentioned it in most of the above. The transformation of this keyboard has not yet been completed. The last part of the keyboard is the transformation of the large keys and key caps. The original paint key caps were rejected by me. First, the original key caps were not light-permeable. Second, The surface of the paint, if the female ticket is in contact for a long time, I fear that the skin on her hand is not good. Although the difficulty of the transformation is a bit large, but the front of so many difficulties have overcome, and the last step is to give it up?
The following is the outline of the keycap transformation, but it is very rude transformation, it is here to remove the stick there ... hope it can do it.
This is my first time doing so many things, there are a lot of imperfections, and I hope to send a post to you to discuss and discuss with the officers. After that, I don't necessarily have the energy to engage in this, but this time I bought a lot of raw materials and I did not engage in it. After the end, there may be some local transformation, such as dyeing a keycap, after all, have some experience. I hope that you will see more support from the officials and give more valuable advice.
the above.
