EMO bets a 4.75mm mechanical keyboard can beat the Magic Keyboard
London micro-maker EMO: 4.75mm fully-mechanical Mac keyboard, $249-349 Kickstarter launch 2026-11-10; 306-point Show HN, Notebookcheck/KitGuru coverage.
Electronic Materials Office (EMO)
What the business is
Electronic Materials Office (EMO) is a London keyboard maker founded by Andrew Emerson; Altar II is its ultra-thin 4.75mm, macOS-first mechanical keyboard with a detachable M-Dial, haptics and a native Mac app, following the Red Dot-winning Altar I.
How it started
Founder Andrew Emerson, a heavy Mac user, posted his first keyboard to HN about four years before Altar II; the response led him to quit his job and make and sell keyboards full time. Altar II took roughly two years, with the hard parts being a tight chassis, battery fit, aggressive power profiling and fitting all components on one side of the PCB.
What happened
Announced 2026-08-06 with a Show HN that drew 306 points and 245 comments. It pairs dual steel-arm scissor switches (40gf) with a CNC-machined aluminium monobody, magnetic detachable M-Dial, Harmonic Synthesiser haptics, red NiteLite backlight, native macOS companion app (Sanctuary), 30-day battery and a 2-minute charge for about two days. Reservations opened at $1 for $100 off; Kickstarter launches 2026-11-10, deliveries expected early summer 2027, at $249-299 campaign pricing and $349 retail.
How it ended up
Still running: pre-launch, with $1 reservations open and the Kickstarter campaign scheduled for 2026-11-10.
Background
Electronic Materials Office (EMO) is a London keyboard company betting that Mac users want a keyboard Apple won't build: fully mechanical, genuinely thin, and designed for macOS. Founder Andrew Emerson's first keyboard post on HN about four years earlier drew enough response that he quit his job to make keyboards full time.
Altar II, announced 2026-08-06, is the bet made physical: a 75%-layout keyboard 4.75mm thick with 1.8mm of travel, achieved by mounting each mechanical switch's tension spring sideways instead of upright. It combines dual steel-arm scissor switches at 40gf, a CNC-machined aluminium monobody, a magnetic detachable M-Dial, haptic feedback, a red night-vision backlight and a native macOS companion app.
The Show HN drew 306 points and 245 comments, and Notebookcheck and KitGuru both covered the launch, noting the Altar I predecessor sold out and won a Red Dot design award. EMO opened $1 refundable reservations, with a Kickstarter campaign set for 2026-11-10, deliveries targeted for early summer 2027, campaign pricing of $249-299 and $349 retail.
As of September 2026 Altar II is pre-launch. The bet is that a small hardware shop can win a niche Apple ignores — and that HN attention plus a $1 reservation funnel can convert into a funded production run.
What has to be true
- Apple won't defend the thin-mechanical niche, so a micro-brand can own it without fighting an incumbent directly.
- A single spec — 4.75mm — is a story anyone can retell, which is why the Show HN and press coverage led with it.
- The $1 reservation before Kickstarter turned interest into a priced queue instead of a wish list.
- Altar I's sellout and Red Dot award gave Altar II a track record before launch.
What can be applied
Claim a niche the incumbent won't defend: with one concrete number (4.75mm) and a bold claim, a two-person-scale shop can carry a hardware launch on HN and press alone.
Aftermath
As of 2026-09-02, Altar II is pre-launch: $1 fully refundable reservations are open on EMO's site, the Kickstarter campaign launches 2026-11-10, deliveries are expected in early summer 2027, and pricing runs $249 (reservation) to $299 (standard backer) with $349 retail. Altar I remains sold out with a Red Dot award. The company is a small team — embedded, electrical and mechanical engineering are listed on the product page — so the campaign outcome will decide whether the bet scales.
