Hi, this is Wayne again with a topic “Building my first mechanical keyboard”.
There’S this recurring joke in the mechanical keyboard community about endgame. ( keyboard, clacking ), Even though you know that the right keyboard could last you pretty much an entire lifetime. Actually finding that keyboard is another matter. Entirely.
I’ve tried everything from traditional keyboards to really retro keyboards. I’Ve even tried some more eccentric designs. But they’re, not quite endgame., And so today I’m gon na try building one from scratch.
(, techno, music ), So I’ve swapped out switches, key-caps cases. One time I switched out a PCB microcontroller, which was a whole thing, but I’ve never actually built one from scratch. And really what I’m looking for is just something that’s completely unique to me.. I want it to be compact.
I want it to be hard-wearing and I want it to be absolutely amazing to type on.. So the main components of the keyboard are a PCB or circuit-board got some key-switches key-caps stabilizers. We got a mounting plate, although this one’s technically optional, USB cable to plug everything into a computer and then a case for everything to sit in.. So a keyboard isn’t made up of too many parts, but actually getting your hands on those parts is another matter. Entirely. They’re, not really something you can just go into a store and buy and, to be honest, even Amazon might be a bit of a stretch.. The Chinese retailer AliExpress has a huge selection, but it can feel like a bit of a wild west. So what I found really helpful is using popular mechanical keyboards forums like the Mechanical Keyboard, subreddit GeekHack DeskThority and find their recommendations.
Tools-wise. Also pretty straightforward.. We’Ve got screwdriver soldering iron plus a couple of soldering iron accessories and, of course, the solder itself.. Oh and I’m gon na say solder rather than sah-der, because well you get it. Keyboards come in all different shapes and sizes, but there are two main types.: You’ve got full-sized keyboards, which include pretty much all the keys you’d expect and then ten-kilos keyboards, which omit the Numpad., But there are also some more esoteric options which you can go for, if you don’t mind having to deal with occasionally some weirdly sized key-caps.. These are tend to be described in percentages.
And the higher the percentage, the bigger the board.. So common types include 60 %, 65 % and 75 % We’re gon na be building a 75 % board, which I think strikes a really nice balance between compactness and functionality.. Also, for me, it’s really similar to a lot of laptop-style keyboards, so it feels very familiar. Step, one we’re gon na wan na test the PCB.. It’S a good idea to test that your PCB is working before you solder anything to it.. In order to test it.
You wan na just use anything: that’s metallic that can connect the contact points and act like a switch will eventually.. There are online keyboard testers that work great here, so just plug your PCB in and test each switch position, one by one. Once we know that it’s working we’re gon na install the stabilizers into the PCB..
Now any key, that’s the equivalent of two letter-keys or wider. Like this, backspace-key needs a stabilizer to stop it from wobbling around. We’re using Cherry stabilizers..
We just clip them together, slot them in to the PCB making sure we use the right holes, because this PCB supports different layouts. Costa stabilizers are another popular option, but I found that they can be a little bit fiddly to attach key-caps to.. Personally, I think both feel fine, but there are plenty of other opinions out there.. Some people like to modify their stabilizers to make them feel less mushy and you can also lubricate them to reduce any stiffness or squeaking if you’re so inclined.. So I’m not going to lie guys. This bit is a lot more fiddly than I thought it was gon na be.. Not only are there quite a few more holes in the board, but also just getting all the right pieces and parts of the stabilizer together before clipping them together is a little bit tricky., So we’re actually building a U.K. or iso layout, because I’m in the U.K.
And I mean also it’s just better., But what that means for the purposes of the stabilizers is the enter. Stabilizer is gon na be vertical rather than horizontal and we’re also not gon na. Have a left-shift stabilizer cause our shift key just that little bit shorter. We’re also not gon na have a right-shift stabilizer, because that key is going to be shorter to accommodate an up-arrow key to the right of it..
So next we have the switches which I think are the most fun part of the keyboard.. I mean they’re literally the thing that makes it a mechanical keyboard.. It’S the thing that defines how it feels and sounds, and there are so many different kinds. I mean there’s Buckling Spring, there’s Alps and there’s Topre., But Cherry MX are probably the most common and they’re what most DIY kits are designed to use.. They each take different amounts of pressure to press and they actuate in different ways.. It’S what gives them their different, sound and feel.. Now I think, Cherry’s website does a great job of explaining the differences between their official switches, but the great news, although maybe not if you’re Cherry, is that their patent has expired. So now loads of other companies and hobbyists are making their own takes on Cherry’s iconic Design. One such company is Zeal PC who manufacture their Zealio switches in partnership with Gateron.
We’re gon na be using a set of their 65 gram, Zealio switches, which I’ve been using on one of my other boards for a little while now.. It’S got this really. Nice tactile bump to it kind of like a Cherry MX clear, but without the scratchiness and stiffness.
It’s a little bit more of a bump than a brown, but there’s less of a click like you get with a blue.. I think the slightly in-betweeny design gives them a really great feel, and it means that they’re perfect for whether you’re typing or gaming., So actually installing your switches is fairly simple. But because this is my first build, I’m gon na take little bit more time to make sure I get it right. Remember this PCB supports multiple layouts. So what I’m gon na do is I’m gon na test each position of the switches with key-caps before I commit to getting solder on them and everything..
So if you find your PCB doesn’t have little holes needed for these plastic legs, then the internet says it’s probably fine to snip them off. Unless, of course, you don’t have a mounting plate, in which case you should really have a PCB that does support them.. It’S finally done Now, it’s time to flip it over and get to soldering., I’m kind of terrified, I’m no soldering expert by any stretch, and I’m not gon na pretend to be.
I’ve linked a video down in the description which I’ve personally found really helpful. But for your benefit here are the general rules. I found. Apply heat evenly to both the switch’s pin and the electrical contact and then apply solder, so it connects the two.
We’re looking for a nice neat cone., Don’t use so much that it turns into a dome but use enough to get a good, solid connection Between the two. And take your time., If the solder isn’t flowing properly than don’t continue to apply loads of heat, because you could break something. Take a moment to let things cool down, re-adjust and try again., You got this. Next, we’re gon na put it in it’s Case. Cases come in all different shapes and sizes, but generally you’ll find they’ll either be made of aluminium or sorry, aluminum or acrylic.. This case is kind of a best of both worlds.. It’S part aluminum, which means that its nice and sturdy, but it’s also got this transparent, acrylic layer, which is great, because this PCB has lights baby, Which of course, I’ll be turning off, because I work in an office with adults. Anyways.
Now we place the PCB and the acrylic inside the case screw the PCB to the case and finally, just screw the whole thing: together. (, deep, sigh ), So finally, it’s time to actually put some key-caps onto these switches.. Now, when it comes to key-caps, if you thought we had a lot of choice when it came to switches, then you are gon na lose your mind at the amount of options here., You can even spend hundreds on individual artisan key-caps, but for this build I’m going To keep it on more on the understated side. I’ve got a set of EnjoyPBT 9009 or nine thousand nine key-caps, which I just love.
The retro look of. Now assembling them is quite easy. You just put them onto the switch and push down. Now these key-caps are made of PBT plastic, which is slightly more resilient than cheaper ABS, plastic and the lettering is printed on using a dye, sublimation process., That’s not quite as good as double-shot key-caps that ensure the Lettering will literally never rub off over time, but it’s a lot better than cheaper laser-etching, where lettering can wear away in less than a year.. But what’s important for our build is that this kit came with plenty of non-standard key-cap options which will fit our weird 75 % layout.. Now that everything’s assembled, we can just plug it into a computer and test that everything’s working..
If we were being extra, we could maybe buy a custom braided USB cable, but to be honest for our purposes, any old mini USB cable will do just fine.. We can plug it into a computer and use that same keyboard, testing tool that we used in the beginning of the build to make sure that everything’s still working. And then fortunately, if anything’s, not working, which you’ll have to open it up and re-solder those switches.
Once you know which one’s the problem. ( keyboard, clacking ), Good keyboard design is timeless, and I mean if you can resist the lure of becoming a bonafide keyboard collector buying the right model can last you the rest of your life.. So this is my first build and I know there are some things that I could have done better, but I want to hear your thoughts.. What’S your advice to firsttime builders like me, How do you build a keyboard first time and make sure that everything works? Let me know in the comments below .
