Pendula is a bluetooth keyboard built around nRf51 chip from
nordic semiconductor.
Battery life is around one year depending on use. The
prototype in pictures uses 2xAAA, but the GB model will use
3xAAA.
One year is with eight hours of typing per day
at six letters per second without having the capslock led
lit.
Case material is laser cut Finnish birch plywood,
which is glued together and hand finished on the visible
sides. The bottom cover is affixed with screws that screw
into brass inserts embedded in the case structure.
The
black one represents what the keyboard will look like as far
as size and shape are concerned, but I’m hesitant about
having that colour as an option as it is a lot harder to
achieve a consistent looking surface with it. The light one
is a previous prototype I built. Both cases feature a hard
wax oil finish, the black one just has two layers of colored
wax applied prior to the clear finish.
Feature list:
- 1 year battery life
- Bluetooth 4.0
- Comes with a birch case (integrated 5 mm plate) and a custom PCB
- Can mate with up to 8 devices, and you can switch between them with less than 1 second delay using a key combo
- Wireless firmware/matrix lookup table updates
- One fn layer
- Supports all whitefox layout options
- The PCB can be cut down to allow for most 60% layout options
- Each plate is cut to a specific layout, no gaps anywhere to ruin the look
- Blockers can be had in any location (for example HHKB/WKL/Whitefox)
-
Costar style stabilizers ( because the PCB is just 1,2 mm
thick, also for their superior feel
)
Future plans: - TMK like layer handling and matrix lookup tables
-
Modify the capslock led to be dual colour for better
indication on connection status etc.
Group buy price will be 350 EUR plus postage.
I will make 10 units as part of the GB.
In order to discourage flippers, I will continue to make these on demand after the GB at a slight markup (undecided, likely around 500 EUR).
Any comments? Am I missing something regarding the description? Is there a demand for wireless stuff? Raffle/FCFS?
edit: layout options:
The blue keys can be removed completely to go from 65 to 60.
