Prototype 1

Hi geekhack, I was recently on the hunt for a board that fit my very specific wants and after a fruitless search I decided to make my own and so, Bean was born.

Details

layout: mx-hhkb, fixed split backspace, fixed split right shift, support for fixed/stepped caps lock
plate/mounting: aluminium half plate, 4 point top mount
typing angle: 6.9 degrees
front height: 14.94mm typing height from bottom of case to the front of r4 keycaps
materials: 6063 aluminium case and half plate, copper rear accent
colours: black case, red plate, red pcb, raw copper accent
pcb: custom 1.2mm pcb designed by Zephyraeon, horizontal flex cuts, usb-c, mx/alps support
kit weight: approximately 800g (case + plate + pcb)

price: under 350usd (high estimate at a very low moq)
sale type: tbc

Plate Design and Mounting

With forced split backspace and split right shift, the board has an almost completely symmetrical layout, allowing for 2 evenly spaced plate mounting points on the top and bottom to give an even typing feel across the board. The impact of this isn't as noticable due to most of the keys being unsupported with the half plate but it gives the mods a pleasant feel.

The other main consideration was the spacebar, a lot of material has been removed under the key as well as a large cutout coming from the bottom, making the switch relatively unsupported and avoiding a harsh bottom out.

Prototype Issues

As expected, there were a couple of issues with the prototype.

1. plate screws hitting the inside of the bottom case - something I didn't account for in the initial design, redesign has already been done to accomodate, pending second prototype

2. rear case screw holes are too tight - the current hole size is too small for the socket head screws i'm intending on using so the diameter will be increased to at least accommodate for that, still considering whether or not to make them much larger for better screwdriver compatibility

3. usb port hole position - still need to confirm final port positioning with another round of PCB protos, currently a cable will plug in fine but the port isn't exactly centred

A second prototype will be on the way shortly.
