after five days, it's finally ready: split, ortholinear layout, robin choc switches and cool special low profile keycaps 😎 story as a spoiler, bc it's rather long, only if you have nothing to do lol <details> i've been eyeing this keyboard for a couple of years, pcbs were semi-available, but the cases, especially the cool metal ones were pretty much never available, always out of stock, or in a group buy that i always missed so when I finally got a chance to buy one, i did so immediately sadly the seller was in the us, so of course the shipping to europe was like 60 dollars, plus import tax, and this isn't to me, this is to a friend in europe (bc of course they don't ship to russia), who later brought it to me during a visit once unpacked and ready to solder (the keyboard wasn't assembled, you have to do it yourself), i suddenly realized that the main controller arrived with a set of pins to be permanently soldered to the pcb, which is suboptimal, as desoldering the controllers is virtually impossible, and a broken controller, a broken pcb, or anything else wrong would mean i'd have to get an entirely new pcb half anyway, the recommended approach is to use sockets, which turned out to be pretty hard to get i spent the first day going to major semi-electronics specialized stores, asking them whether they have something close to what i needed, they sold me components which seemed right, but once home and having checked them, turned out to be incorrect on day two i went to the largest electronics specializing store in the city, to all three of their locations, one of them was closed early bc of holiday season, second sold me something which worked, but not very well, and last one told me they didn't have anything ok, last resort, i went to the "radio parts market", which is absolutely enormous, like 15 storeys high, huge floors, literally thousands of small shops, and you can very easily get lost and wander for a long time, literally like a labyrinth, all located on the outskirts of the city anyway, after traveling there, i spent maybe a couple of hours walking among the knee high piles of soviet-era electronic components, asking around whether they have what I needed, until some kind shop owner sold me the correct sockets, only for me to learn that the pins that were supposed to be inserted into these sockets were of non-standard size and shape (circular and smaller than regular square shaped ones), which are apparently rarer than gold everybody i asked for them sent me to some mysterious tiny shop, located on the underground floor, for which you need to navigate quite a lot to get to, anyway, once arrived, i catched the owner literally half-closing the propective anti-theft garage-door-esque thingy to protect showcases usually, asked him whether they had such pins, only to learn they didn't i was in a dead end, it was like 8pm, pretty dark, -20 outside as i exit the market, unsure what to do, so i just got to the nearest cafe and pondered what i should do nothing came up, so i just went home, dug up some diodes, cut some wire off of them, and DIYed the pins that fit the sockets out of them a little bit of soldering later, i learned that apparently i soldered the microcontrollers incorrectly, upside down that is, probably because the atmega chip powering them and other boards such as arduino nano, is supposed to be facing up in arduino nano (which i've soldered many times before), therefore i just intuitively soldered the pins to the controller, so that the atmega chip faces up, which is incorrect i desoldered the pins, soldered new ones again, only then to realzie that if I heated the solder and pushed the legs through the holes in the microcontroller, the legs would get covered in solder, thus potentially compromising the contact with the sockets, so I had to desolder the legs once again, solder these legs again, now to the other side, and spent quite some time reheating the solder and making small maneuvers to the legs in order to allign them correctly, so that they're insertable into the sockets there were a lot of other minor troubles, like accidentally starting to insert the switches into the pcb without putting the plate in-between them, thus having to later de-insert all the switches, but all in all, it came out successfully, even the controllers survived all that resoldering </details>

## A problem with Keyhero I've been using Keyhero for some time now. It looks ok, and it's nice to be able to operate (skip quotes, start new ones) without using your mouse. And the quotes can be interesting. At some point I noticed that my typing speed progress basically plateaued. Then I noticed that Keyhero either has a really weird algorithm calculating typing speeds, or is simply misreporting them. As you can see in the screenshot, the average speed is stated as 111 wpm, which is a speed that I literally ***never went below***! Looking at the graph you can see that the speed is more likely 140 or 150 wpm. I was primarily using Keyhero without an account, but then I noticed that every time you reopen Keyhero, it sets the average speed by default as 35 wpm (what?). Maybe the per-game average is somehow tied to the overall average speed (for whatever reason) I thought, maybe that was the issue? But then I registered an account, and got my average speed from the initial 35 wpm to about 120 wpm (it took a long time, because the 35 wpm already had some average weight to it for whatever reason). But the problems persisted. The average speed is consistently 20-40 wpm lower than my actual speed. Has anyone had a similar problem using Keyhero? ## Any alternatives? So I started looking at alternatives, and noticed that a lot of them also misrepresented my average typing speed (a lot less than Keyhero), most of them use CloudFlare, have ugly UI, and tons of spyware. Any alternatives (maybe even a standalone app instead of a website) that you could recommend?

I use a German keyboard but switched to the QWERTY layout to input programming symbols more easily. I still want to be able to type German umlauts, though. My keyboard also has a `alt gr` key that I want to put to use. So I created the file `~/.xkb/symbols/us-custom` with the following contents: ``` default partial alphanumeric_keys xkb_symbols "basic" { // Umlauts (ä, ö, ü) and € include "us(de_se_fi)" name[Group1] = "US layout plus some Unicode symbols using altgr combinations"; // <AC06> means: middle row, 6th key on the board from the left // Unicode arrows (←, ↓, ↑, →) key <AC06> { [ h, H, U2190 ] }; key <AC07> { [ j, J, U2193 ] }; key <AC08> { [ k, K, U2191 ] }; key <AC09> { [ l, L, U2192 ] }; // Typographic punctuation key <AE11> { [ minus, underscore, endash, emdash ] }; key <AB09> { [ period, greater, ellipsis ] }; key <AB10> { [ slash, question, division, questiondown ] }; key <AE08> { [ 8, asterisk, 8, multiply ] }; key <AC11> { [ apostrophe, quotedbl, rightsinglequotemark ] }; // Quotes key <AB02> { [ x, X, guillemotright, 0x100203a ] }; key <AB03> { [ c, C, guillemotleft, 0x1002039 ] }; key <AB04> { [ v, V, doublelowquotemark, singlelowquotemark ] }; key <AB05> { [ b, B, leftdoublequotemark, leftsinglequotemark ] }; key <AB06> { [ n, N, rightdoublequotemark, rightsinglequotemark ] }; }; ``` In line 4 I included the `de_se_fi` section of `/usr/share/X11/xkb/symbols/us`. This has the same effect as putting the following into my custom layout: ``` include "us(basic)" include "eurosign(e)" key <AC01> {[ a, A, adiaeresis, Adiaeresis ]}; key <AD09> {[ o, O, odiaeresis, Odiaeresis ]}; key <AC02> {[ s, S, ssharp, U1E9E ]}; key <AD07> {[ u, U, udiaeresis, Udiaeresis ]}; key <AD10> {[ p, P, aring, Aring ]}; include "level3(ralt_switch)" ``` Including `level3(ralt_switch)` allows me to access the third layer by holding down the right `alt` key. This is how you access the other layers: - 1: hold down nothing - 2: hold `Shift` - 4: hold `Shift+alt` With the `key` keyword you can remap a key. In the angle brackets you specify the position of the key on the keyboard. The second letter specifies the row: - B: bottom row - C: middle row - D: top row - E: number row The next two digits specify the position on the row starting with `01` from the left. The next bit of syntax is self-explanatory: {[ layer1, layer2, layer3, layer4 ]}; You can leave out layer4 to map it to nothing. You then should be able to select your custom layout. If you use Sway, add the following to the config file. input * xkb_layout "us-custom" Alternatively, export the [environment variable][1] `XKB_DEFAULT_LAYOUT=us-custom`.
