Doesn’t this look fantastic? Hard to believe it, but the base of this keyboard began life as a cutting board, and there’s a gallery to prove it. This is actually [androidbrick]’s second foray into this type of upcycling.
This time, [androidbrick] used a FiiO KB3 and replaced the bottom half of the plastic shell with a hand-routed kitchen cutting board. The battery has been disabled and it works only in wired mode, which is fine with me, because then you get to use a curly cord if you want.
Image by [androidbrick] via redditThe switches are mostly Gateron EF Currys, though [androidbrick] left some of the original Gateron G Pro 3.0 on the stabilized keys just for comparison. As you might imagine, the overall sound is much deeper with a wooden bottom. You can check out the sound test on YouTube if you’d like, though it’s pretty quiet, so turn it up.
Those keycaps look even nicer from top-down, which you’ll see in the sound test video linked above. Just search ‘JCM MOA GMK’ on Ali and you’ll find them in a bunch of colorways for around $20. Apparently, [androidbrick] was saving them for months, just waiting for this build.
It’s been a minute since I featured a tiny keyboard, and that’s okay. But if you want to get your feet wet in the DIY keyboarding community, making a little macro pad like [Arnov Sharma]’s Paste Pal is a great place to start.
Image by [Arnov Sharma] via Hackaday.IOThis is a follow-up to his original Paste Pal, which only had two buttons for copy and paste plus an OLED display. This updated version does three more things thanks to a total of five blue (!) switches. The selected command shows up on the screen so you know what you’ve done.
Right now, [Arnov] has the Paste Pal set up to do Copy, Paste, Enter, Scroll Up, and Scroll Down, but changing the assignments is as easy as updating a few lines of code.
Paste Pal Mk. II is at heart a Seeed Xiao SAMD21, which in this case is programmed in Arduino. If you want to make things easier on yourself, you could program it in CircuitPython instead, although [Arnov] includes the Arduino code in his excellent build guide.
Have you ever wished you could experiment with different layouts super easily, just by adding or removing a few switches here and there and printing a new case? Well, [heyisjambo] says that it’s more than possible with menura, the modular keyboard system.
So many lovely options! Image by [heyisjambo] via GitHub[heyisjambo] is happy with 36 keys, but is reduced-count-curious and wanted a way to explore without a lot of wasted time and PCBs.
At the same time, [heyisjambo] wanted to experiment with split vs. uni-body construction, and especially the different shapes that are possible when tweaking the angle and distance between them.
And as if that weren’t enough, there’s support for [Sadek Baroudi]’s VIK standard for interfacing data between PCBs, which calls for an FPC 12-pin, 0.5 mm pitch connector and allows for ultra-cool magnetic connectors. This way, you can easily add things like displays, trackpads, and trackballs in the between the halves.
When [coral-bells] posted her first build to r/mechanicalkeyboards, she likely felt some trepidation. After all this is reddit we’re talking about, so right away you’ve got two layers of male-domination hobby.
Image by [coral-bells] via redditWhat she likely didn’t expect was to be upvoted into the tens of thousands, or to receive such a response from other girlies who came out of the woodwork to share their builds.
And so r/keebgirlies was born, and already has a few thousand members. This is a brand-new subreddit for women and non-binary folks who are into mechanical keyboards. As it says in the sidebar, men are welcome but limited to the comments for now, so don’t go trying to post your builds. The girlies are currently seeking moderators, so give that some thought.
As for [coral-bells]’ lovely build, this is an Epomaker MS68 with MMD Vivian V2 switches, and those flowery keycaps are from Etsy. She is currently waiting for supplies to mod a Yunzii AL66, but wants to build a kit at some point.
You know (or maybe you didn’t), I get super excited when y’all use the links at the bottom of this round-up we call Keebin’ to communicate with your old pal Kristina about your various labors of love. So just remember that.
Case in point: I was typing up this very issue when I heard from [Jay Crutti] and [Marcel Erz]. Both are out there making replacement keyboards for TRS-80s — [Jay] for Models 3 and 4, and [Marcel] for the Model 1. Oooh, I said to myself. This is going at the top.
A TRS-80 Model 4. Image by [Jay Crutti] via JayCrutti.comRelevant tangent time: I remember in the 90s having a pile of computers in my parents’ basement of various vintages, a TRS-80 Model 2 among them. (Did I ever tell you about the time I got pulled over for speeding with a bunch of different computers in the backseat? I was like no, officer, first of all, those are old machines that no one would really want, and I swear I didn’t steal them.)
I think the TRS-80 is probably the one I miss the most. If I still had it, you can bet I would be using [Jay] and [Marcel]’s work to build my own replacement keyboard, which the 40-year-old machine would likely need at this point if the Model 4 is any indication with its failing keyboard contacts.
To create the replacements, [Jay] used Keyboard Layout Editor (KLE), Plate & Case Builder, and EasyEDA. Using the schematic from the maintenance manual, he matched the row/column wiring of the original matrix with Cherry MX footprints. Be sure to check out [Jay]’s site for a link to the project files, or to purchase parts or an assembled keyboard. On the hunt for TRS-80 parts in general? Look no further than [Marcel]’s site.

Image by [jwr] via redditThe Ultimate Hacking Keyboard (UHK) line is, as the name suggests, a great choice for a lot of people. They’re each a toe-dip into the ergonomic waters with their split-ability and those beginner thumb clusters.
However, [jwr] was not completely satisfied and decided to make a custom set of keycaps. The idea was to create ‘caps without the “annoyingly abrasive texture of PBT”, that are larger than average for larger-than-average fingers. Finally, [jwr] wanted the Function row to tower over the number row a little, so these have a taller profile.
So, what are they made of? The look kind rubbery, don’t they? They are cast of pigmented polyurethane resin. First, [jwr] designed five molds in Fusion360, one for each row. Then it was time to machine master molds via CNC in foam tooling board. These were filled with silicone along with 3D-printed inserts, which produced silicone molds for casting keycaps four at a time in resin.
Image by [New-Concentrate6308] via redditDon’t worry, [New-Concentrate6308] is working on the GitHub for this final build of 2024, dubbed the GEMK_47. That stands for Grid Ergo Magnetic Keyboard, but I swear there are 48 keys.
What we’ve got here is a split ergo with an ortholinear layout. There’s a round screen and encoder on the left side, and a 35 mm trackpad on the right. There’s also space for some other round thing on this side, should you want another rotary encoder or whatever fits in place of the spacer.
Internally, there’s a Waveshare RP2040 Tiny and a mixture of Gateron Oil Kings and Gateron Yellow V3 switches. That lovely case is printed in silk silver PLA, but [New-Concentrate6308] wants to try metal-filled PLA for the next version. Although the original idea was to go wireless, ZMK didn’t play nicely with that round display, which of course is non-negotiable.
