this is ALU40, the first ever wireless true ortholinear mechanical keyboard designed by huiben's cofounder in collaboration with polarity works to complement apple devices. at 23-27mm tall using square keycaps like f10, it's also the slimmest ever keyboard with full height mx switches while still fitting a large 1800mah battery originally designed for iphone for months of uninterrupted use. the bead blasted finish, typing angle, and other details perfectly match peripherals such as magic trackpad and studio display. the pcb rests on evenly distributed standoffs suspended on rubber gaskets in the single piece enclosure for a very consistent and firm yet insulated typing feel.

the partially assembled option will be ready to add switches and keycaps, and is hand assembled by me and shipped from brooklyn ny.

the diy option is for those who would like the full build experience of assembling the battery, screws, and gaskets, or would like to make modifications such as case foam or stabilizers in addition to adding switches and keycaps.
