In this instructable I will show you how to build your own custom USB keyboard that behaves just like a regular computer keyboard. You can assign any key combination or sequence of keys to be pressed while pressing only one pushbutton. You can use it to optimize your computer work by assigning various key combinations to just one physical key, so it makes your life easier. I used it to control my CNC router manual movements, since I found using regular computer keyboard too bulky and cucumbersome to use.
Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. But you can use any pushbutton switch as you like, if you don't need the fancy LED effects.
I used some RC debouncing circuit for the switches see imageso there is no need to worry for switch bouncing in the software. The LEDs in the switch have common anode.
If you are going to use breakout board, check the breakout board schematics. It should be pretty straightforward to connect the wires. You probably don't need to use the 7 decoupling capacitors if you will use breakout board for LED driver. The PCB is not necessary step in this instructable, because I used non-hobby friendly programs and my switches are ridiculously expensive to buy, so I believe not many of you will actually make this very PCB that I made.
I encourage you to wire the project using breakout boards and protoboard wiring, or you can design your own PCB which will fit more affordable switches and LEDs. I designed a quick pcb in Altium Designer. I used this program because I have a license, since I use it for work every day.
I know this program is nowhere near hobby friendly price wise. The box was drawn in Autodesk Inventor also not hobby friendly program, but I use that at work too and I am used to it. If anyone wants.
I used the Button library for managing all the buttons. It has nice features for reading buttons like key. Integrated arduino Keyboard librar y for making the board behave as PC keyboard. TLC library for controlling the led dimming and making all the nice fade ins and outs.
I attached the final arduino code. Keys are mapped similar to the regular PC keyboard in the code as per the attached image for easier handling. Question 1 year ago on Step 4. You wouldn't happen to have a Fritzing of your diagram, and a more detailed PCB design? Answer 1 year ago. Yes there was a typo. Already corrected. The correct one is TLC I used 2 ICs because I needed 30 channels. The library handless all the stuff so you just need to wire it correctly. Look at the net names. Same names connect together through the schematic.
Just follow the names and imagine a wire between same names.Joinsubscribers and get a daily digest of news, geek trivia, and our feature articles. Mechanical keyboards are generally touchier than their counterparts, and occasionally a switch will falter. It takes some tools and a little know-how, but you can absolutely do it. Always use caution when operating them, and never leave an active soldering iron outside of its holster.
If you continue with this guide, you do so at your own risk. This guide presumes a basic knowledge of soldering techniques. This is more complex than you might think. Broadly speaking, yes. The next big choice is the mount style. On the left in the image below is a keyboard with plate-mounted switches; on the right, a keyboard with PCB-mounted switches. You can generally install a PCB-mounted switch onto a plate keyboard without issue—even if the extra plastic prongs are in the way, you can snip them off and sand them down.
Otherwise the light will be blocked by the opaque switch.Pcl to pdf
To start this process, remove your keyboard from your PC and place it in a clean workspace. This process will be different for different keyboards. On our example keyboard, a rather typical, mod-friendly Vortex Poker 3 design, all I have to do is remove the keycaps and then remove six screws. If you have a more elaborate gamer-style keyboard, you might need to pry off plastic bits and remove the feet to access retention screws.
As you work, make a note of which particular switch you want to replace. Now plug in your soldering iron to warm it up, and get your pump ready. Place your PCB upside down on your work area, with the back of the board facing up and the switches resting on the table.
Prepare your sponge or brass for cleaning. When your iron is hot enough, clean off any oxidized residue so that the tip is clean and shiny. Then press the tip to the electrical prong of the corresponding switch to heat up the old solder until it turns liquid. Be careful not to touch the non-conductive material of the PCB itself, just the solder. Have your pump primed and ready. When all of the solder is heated and liquified, quickly move the iron away and place the pump on top of the pin.
Activate the pump to suck the liquid solder away from the electrical contact before it cools and re-solidifies. Do so, then repeat the step for the second contact on the switch. Remember to clean the tip of the soldering iron regularly as you work. With the solder removed, you can now physically remove the switch itself.

If the keyboard uses PCB-mounted switches, you should be able to simply pull it out with your fingers or small pliers. Solder is sticky stuff that dries quickly. Repeat Step Three and try again. You may have to do this for above-switch LEDs, too.
When you have the old switch free, set it aside.Availability : In stock. Vendor : KPrepublic. XD84 PCB. If you order our products, we assume that you agree with the above terms.Grey uniformity test

Fully programmable using QMK. Additional information Weight 0. Rated 5 out of 5.Thank you for supporting the work I put into this site! In my opinion, a gaming PC without a mechanical keyboard is not complete, because you cannot have that right kind of feel and response in games with a membrane or rubber dome keyboard, even if it is a gaming one.
Some users prefer mechanical keyboards with single-color backlighting, especially white LED backlighting, and some want to go one step further and prefer a mechanical keyboard with RGB backlighting because they look fancy and you can customize the keys to different colors that can help in gaming too. Gaming mechanical keyboards with RGB lighting were pretty expensive a while back, but now they have become much more affordable and you can easily find a good RGB mechanical keyboard from a reputed brand under dollars.
But if you have a lower budget, then also you can find a decent Chinese RGB mechanical keyboard under 50 dollars price range. So, to help you select the right RGB mechanical keyboard in your budget, here I am going to list down the best RGB mechanical keyboards for every budget for your gaming and typing needs.
For example, a Rainbow keyboard can have Red, Blue, Green, and Violet colored LEDs, in which LEDs of similar color can be arranged row-wise, column-wise, or block-wise pattern depending on the manufacturer.
This means you can assign different colors to each key or can assign a different group of keys with different colors depending on your mood or requirements. So, to sum up:. A compact Tenkeyless RGB mechanical gaming keyboard that comes with 87 keys. The mechanical switches are tactile and make a clicky sound. They are lighter than Cherry MX Blues in terms of operating force but are a bit louder than it.
The keyboard has Double-shot injection molded keycaps for clear and uniform backlighting, and the letter markings do not wear off too due to it. It has got multimedia keys shared with the function keys, and they can be launched in conjunction with the special FN key.
The build quality of the keyboard is solid, and it has got a metal backplate for durability and rigidity. The RGB lighting effects and brightness can be controlled and customized on-the-fly as it does not support software. There are five different lighting modes, five backlit brightness levels and it also supports user-programmable RGB backlighting. This is a good value for money RGB mechanical keyboard that can be used for gaming and typing as well, because of the blue switches.
The USB cable on this keyboard is non-detachable and it comes with gold plated USB connector to prevent it from corrosion.
This is basically a full size keys version of the above mentioned Redragon K RGB mechanical keyboard. This may be a full-sized keyboard but it still features a very minimalist design with no extra protruding sides.
It does not support RGB lighting through software and it can be customized and controlled by using the specified keys with FN key. So, if you are looking for a budget full-size RGB mechanical keyboard then this one will fir your bill perfectly.Dalla lite tra corona e cecchi paone alle gaffe di amadeus e carrà
A very good looking RGB mechanical keyboard from Havit that offers many extra features that no other RGB mechanical keyboard offers in this price segment. The keyboard comes with custom Blue mechanical switches that are clicky and tactile, require 60 gf of actuation force, which is the same as a Cherry MX Blue switch too. However, it feels a bit different from the original Cherry MX Blue switches, but it is pretty good. The keycaps are ABS double-shot injection that allows uniform RGB lighting, and makes the letter marking permanent, which cannot be erased by any means.
On the top of the keyboard, you will find dedicated multimedia buttons, a volume rocker wheel, and five custom keys M1-M5 that are used to store the custom RGB lighting pattern or combination, which you can set according to your preference or requirements. The RGB lighting and effects can be controlled and customized with the keyboard keys itself by using the Fn key, and it does not support any software for it.
The build quality is solid and it comes with a braided USB cable. The hand rest is pretty small for most of the people, which I think should have been made detachable. Also, you will get a phone holder at the top, on which you can place your smartphone. This comes in really handy when you are working on your computer, but have something important going on your smartphone too, and you need to keep a track of it. Overall, a good feature-rich, practical, and attractive looking budget RGB mechanical keyboard that is definitely a steal at this price.
Here we another RGB mechanical keyboard from Redragon, but this one comes with Outemu Red switches that are linear, quiet and non-tactile mechanical switches, designed for faster response in gaming.In the world of mechanical keyboards, brand names like Corsair, Razer, HyperX, etc.
The majority of these brands claim to offer the best in terms of quality and functionality, but that's not always the case. While the popular gaming brands have pushed the awareness and adoption of mechanical keyboards into the mainstream, compromises on quality are almost always made in order to lower prices.
But what if I told you that every part of a keyboard can be customized. This goes far beyond the aesthetics of buying the latest keyset from Massdrop or swapping in a braided cable. If you want a programmable keyboard in a 60 percent format with dedicated arrow keys but it is only available without the programmability, then you will need to make compromises and choose the features that are most important to you.

All of these parts have a wide range of options to personalize your keyboard and many options for one part can determine or limit your options for another.
Choosing the right places to buy your parts from can be pretty difficult if you've never built a keyboard before. Your first instinct might be to hop onto Amazon and start searching for parts. You can find some good options this way but it's much easier if you can get multiple parts from the same source. There are a few different stores I like to buy my parts from. It's entirely possible to get everything you'll need from them, but their keycap selection leaves much to be desired.
Their case selection isn't as robust as KBDfans but if you live in the US, you can save on shipping by ordering from them. If you're looking for basic keysets to get your board up and running, either of these stores will have you covered.
If, however, you are looking for something a bit more unique and with a wider range of compatibility, you'll need to look elsewhere. Massdrop is a great way to get more expensive and limited run keysets at significant savings if you're willing to wait for them to drop and ship. If you're not willing to wait and you're prepared to spend whatever it takes, Originative offers a wide variety of keysets from high quality brands like GMK and Signature Plastics.
Before choosing your case, you need to decide what size of keyboard you want to build. Once your have decided on the size of your keyboard, you need to decide on which material you want your case to be made from. Cases are usually available in one of 4 different materials. Aluminum is the most expensive option but offers the strongest platform for your keyboard. The added weight can help keep your keyboard in place during those heavy work or play sessions.

Other than cost, the main downside is the effect on acoustics. Typing on a keyboard with an aluminum case can be much louder and provide a more metallic and hollow sound.Joinsubscribers and get a daily digest of news, geek trivia, and our feature articles.
The plastic case and high-end PBT keycaps are offered in a variety of colors, including a fetching side-printed option that preserves the legends under constant typing. Different colors, LED backlight colors, and a wide selection of Cherry or Gateron switches are available.
This is due to a combination of easy mobile support with a purpose-made Android programming app, easy availability from vendors like Amazon, and full RGB LED support. It has extra media and connection keys, but does without backlighting to save battery, which Logitech says can last 18 months on two AAs.
Function keys cannot be reprogrammed, including the awkward F11 and F12 keys on [ and ]. The Professional BT model is offered with key legends or without in a single gram Topre switch design. A windows application allows more or less unlimited programmability, including the RGB backlighting.
It also appears on Massdrop occasionally. This odd-looking design is the only Bluetooth mechanical model specifically made for macOS. Cherry clone switches are offered in Blue, Brown, Red, and Black varieties. Given the limited options for Bluetooth and the proclivity of mechanical keyboard enthusiasts to roll their own, there are quite a few custom-made keyboard designs that add a battery and Bluetooth controller to an existing layout. If you can program your own layout and solder your own keys to a PCB or even do the custom wiring yourselfyou should be able to use a popular add-on like the Raspberry Pi Zero W to modify or create your own Bluetooth mechanical keyboard.
