1 iota

40% keyboard the size of a 30%

  • 16mm switch spacing instead of standard 19.05mm
  • PCB mount switch with diode installed inside the switch
  • Efficient 6x8 matrix
  • Cut down SP DCS and DSA keycaps 
  • Slightly larger than a Gherkin 
The 6x8 matrix uses the fewest i/o pins for the 48 keys. There are 4 pins left over one the Pro Micro.

The keycaps are from PMK grab bags. The DCS keycaps are all Row 1 ABS. The DSA keycaps are all PBT.

The keymap is the same as I use on my Gnap. It is definitely easier to type on than the 16mm 30% since you don't have hit layer modifiers as often, which is more difficult to do with the smaller keys.

16mm Jelly Comb

Jelly Comb recycled into a 16mm 30%

Completely disassembled a Jelly Comb TKL. Reused the switches, LEDs, and keycaps in a 30% with 16mm switch spacing.

The Jelly Comb TKL was $26 shipped from Amazon during a sale. This model is no longer available. The plate is aluminum and the body plastic. It had plate mount stabilizers. The LEDs were a different color in each row.

The parts were used in a 16mm PCB/case. The keycaps were cut down to fit the narrower spacing.

The plate mount blue clicky switches are branded "Long Hua".

New Gherkin Plates

Plates with switch top removable cutouts

  • 14mm square cutouts replaced with switch top removable cut outs
  • Notch in top plate removed
  • Notch in bottom plate slightly deeper
  • Back sides are blank
  • Compatible with previous version top/bottom/pcb
  • Previous version
Tested the cutouts with Gateron and Cherry switches. Removed the USB notch in the top plate, it really was not needed. The new switch cutout also came closer to where the notch was, it would have been a weak spot. The notch in the bottom plate is slightly deeper so that some larger USB connectors will fit.

The top plate is not symmetrical. The USB connector would go on the end with the printing.

Self Flashing LEDs

Self flashing LEDs

  • Fast cycle RGB
  • Slow cycle RGB
  • Red/Green
  • Warm white candle flicker
These LEDs have their own built in controller that cycles through a preset pattern. The most you can do is turn them on or off.

The fast cycle and slow cycle RGB are 2x3x4mm LEDs. The red/green and flicker are 3mm flanged LEDs. Most 3mm flanged LEDs will fit in Gateron tops.

It takes a few minutes for the RGB to look random. You can see the Q/W on the slow cycle RGB have a dead blue LED.

The red/green almost look like an 8bit animation after a while. When powered through a PWM signal they appear orange, with both the red and green LED elements lit.

The candle flicker LEDs also come in colors other than white.

The LEDs were all purchassed on eBay, search for "self flashing led".

16mm PCB plates

Added PCB top and bottom plates to the 16mm PCB

The plates allow for plate mount switches to be used. The new Kailh switches and the Cherry speed switches are currently only available in plate mount. The shorter actuation point and a shorter bottom out (with o-rings) might be an improvement.

I also printed a Pro Micro pin out diagram and some verbiage about the power pins on the bottom plate.

Some pictures side by side with the plateless version.
