Hey, what's up everyone!

Welcome back for another recap and behind-the-scenes write-up – with June's best-selling switches, some cool projects from the DIY keyboard scene, but also promising closed-source projects or even prototypes. Read about goodies in my mailbox from Apos and 3dkeycap, upcoming meetups, and much more.

If you are new to kbd.news, you can read how this started out and what this is all about nowadays. If you like what you see, subscribe to the newsletter (free) and donate some bucks to keep this otherwise free and ad-free project alive.

Just got back from my holiday btw, so I have a huge backlog. That said, the cutoff date for this issue was about 10 days ago. I've been busily bookmarking interesting projects in the meantime though, so I'll feature more recent stuff in the coming days.

Some posts worth sharing

  • In this latest market overview of the best-selling mechanical switches, here are June's top picks, based on sales data provided by vendors and manufacturers. Some late data added – worth another scroll even if you've read it after publication.

Tip

  • Typing tests: Typecelerate by sock_pup is a practice app that targets your weaknesses. And typingspeed.app by No_a mApricot is a simpler one.

  • RazgrizHsu's karabiner-ts-config is a TypeScript-based tool for building Karabiner Elements configuration files with type-safe Fluent API design.

Transform hours of repetitive JSON editing into minutes of elegant TypeScript programming. Our real-world example (raz.ts) demonstrates an incredible 78x efficiency improvement – Raz.

Closed-source, commercial, WIP, etc.

  • Nuty60 by Nutylabs. A nice split with low-pro KS-33 hotswap or MX soldered switch support.

According to the USB-IF (people who define what USB devices are), a true "keyboard" must have a minimum of 103 keys – binpax.

In the mailbox

  • A gorgeous NPKC Studio RO75 was sent to me by Apos. Thanks! Looks and feels great, cool color options with matching keycaps. Review soon.

Pic:

  • In addition, a set of keycap tilters from 3dkeycap's Loïc, along other samples. The tilters are a prototype set to convert any MX-compatible keyboard into a contoured, DIY keywell board. (Not yet available, but check out all the nice keycaps and accessories offered by 3dkeycap.)

Vendors & Discounts

Feel free to use the KBDNEWS discount code at 178 keyboard shops! And do not hesitate to report any issues!

New shops and updates to the database of keyboard vendors this past two weeks:

  • Bowl Keyboards (US) added.
  • Sunder (Singapore) added. Pre-built Hall effect splits, like the new C60 HE mentioned above.

Developments

I’m building out the switch comparison feature: side-by-side specs, plus a way to find alternatives based on how closely a switch's attributes match others. Actually, I'm almost finished, some testing is still needed though. To be rolled out later this month.

That's all for today. Thanks for checking by. As always: Keep learning and building!

Until next time,
Tamás
