Description

a not-so-small keyboard with a fishy layout

README

small-fry

rev. 1 prototype

parts needed

• 1x Raspberry Pi Pico (make sure you get an authentic one with the castellated pins)
• 69x SOD123 diodes (e.g. 1N4148W)
• 69 MX or Alps switches (i strongly recommend MX unless you are confident in fabricating your own keycaps)
• 2x 2U stabilizers
• 53x 1U keycaps
• 14x 1.75U keycaps
• 1x 2.25U keycap
• 1x 2.75U keycap

tools needed

• a heat gun + solder paste are highly recommended for soldering the diodes, however they can be hand-soldered if you are patient and skilled.
• soldering iron + solder wire for soldering the switches and MCU.

assembly notes

• diode direction is COL to ROW! this means the lines should face down (if you're using the diodes linked above).
• this PCB does not have holes for tray-mounting; it must be plate-mounted to a case.
• switchplate .DXF file is included; it should be ~1.5mm thick. recommended material is either metal or FR4. acrylic is technically viable but will add flex.

sandwich case notes

some .DXF files are included for a rudimentary sandwich case. additional hardware needed:

• 10x M3x8mm male-to-female standoffs (M3x10 will also work, just makes the height taller)
• 10x M3x4mm screws
• 10x M3x6x5mm heat-threaded inserts

required thickness of each plate:

• top plate: 1.5-3mm
• mid plate: 3mm
• buffer plate: 3mm
• bottom plate: 1.5-3mm

stacking order of plates is, from top to bottom:

• top plate
• mid plate
• buffer plate
• switch plate
• bottom plate
