Introducing the humble40
The Group Buy page is up!
Update (June 6 2022): Well, I didn’t
expect things to take this long, but this project is ready
to go. This group buy will go live on 17 June at a time TBD.
I’ll be selling at
www.eyeohdesigns.com
The plan is this to run for 3 weeks, or until 75 units are
sold, whichever comes first. Estimated completion is 4
months after the group buy is closed.
One big change is
that the PCB was redesigned to run an RP2040. The firmware
is now Vial.
Update (July 5 2021): Hey
peeps! Protos have arrived and I’m very happy with the
outcome! There are still some things to tweak and decisions
to make before moving to GB. Namely, those are:
-Determine
optional plate materials. Base kits will include FR4 and
other materials will be available as an add-on. I have
prototypes of brass, FR4, and POM. The POM may prove too
flexy, but I won’t know until I get to do a complete build
with the new PCBs. Which brings me to the next decision
point…
-Determine PCB thickness. I may end up going 1.2
mm PCBs instead of the standard 1.6 mm thickness. This would
be in-lieu of a half plate option, which doesn’t really make
sense for the size and construction of this board.
-Determine
manufacturer. This will determine pricing. The current
protos I have are great quality and from a cheaper
manufacturer. Unless the more expensive manu blows me away
with their quality, I’ll likely go with the less expensive
option to help with pricing.
-Minor tweaks to the
case.
I think my next update will be when I receive the
next round of protos. Stay tuned!
The humble40 is the
latest board from Eye Oh Designs and is the first keyboard
in the humble series. The humble40 combines no-nonsense
mounting in a simple yet handsome 40% package. Its features
include:
Case/Plate:
-12.5u WKL
layout
-Bottom mount. Compared to other bottom mount
boards, there is a decent amount of flex due to the cutouts
for the blockers and using only 4 mounting points for the
plate/PCB.
-5.5 degree typing angle with 19 mm front
height.
-Seamless, single piece CNC construction.
Planned materials are anodized aluminum and polycarbonate
based on interest check response.
-FR4 switch plate in
standard stagger or uniform stagger configuration.
-Case
foam likely for all kits. Plate foam available as an add-on.
I’m still tweaking these details.
PCB:
-Compatible with MX style switches. Soldering iron
required.
-Powered by a RP2040 running Vial
-USB C
connection and circuit protection through the unified
daughterboard
-Standard and uniform stagger
configurations on the same PCB
-Single color LED
backlight optional (All required circuitry will come on the
PCB except the in-switch lighting. The customer can add this
during the build if they desire)
Keycap
compatibility:
-Complete legend and profile accurate
coverage by most of the DSS sets coming out of the 40s
Discord sold through store.aeternus.co, cbkbd.com,
ringerkeys.xyz, etc.
-Depending on layout chosen, near
GMK base kit coverage. The only out of profile key is tab
(put 1.25u tab in base people).
**Pricing: $170
Planned
units: 75
Planned vendors:
www.eyeohdesigns.com
Timeline for GB: 3 week group buy. Fulfillment 4
months after group buy completion.

Some notes
on the humble series mentioned above:
The humble series
aims to offer keyboards that dont compromise on looks,
sound, construction, or price. My aim was to provide
something that is simple, yet handsome and refined. You wont
need the keyboards blueprints or an entire box of screws to
put it together, but your typing experience will be just as
enjoyable once its complete. I plan to offer a few more
keyboards under the humble name with the same design
language, so stay tuned.
