40% Keyboards: 6lit

40% Keyboards A blog about small mechanical keyboards. Home Firmware Parts Vendors corrects IE6 width calculation Wednesday, September 13, 2017 I wanted to make a 6 key macropad that would fit within the 100mm x 100mm PCB size. Since I have been making split keyboards lately I added the same circuitry to this. I can't think of a practical use for a split macropad, but it works. It can be used singly as a regular 6 key macropad as well. Other than the size the construction is the same as the foobar and the 16mm Split 40% keyboards. The modified firmware is on github as are the gerber files . The PCB is smaller than 100mm x 100mm so you can get it made at a discount at EasyEDA or JLCPCB . I am runnin...

40% Keyboards: Gherkin Gore

40% Keyboards A blog about small mechanical keyboards. Home Firmware Parts Vendors corrects IE6 width calculation Thursday, August 16, 2018 Found Gherkins on Amazon. This is what arrived. It was loose in a large box with several other items (That now smell like pickles). The only padding was the bunched up brown paper. Gherkin gore. 4 of the 12 bottles were cracked open. There must be a trail of pickle juice somewhere. Posted by kb Email This BlogThis!

40% Keyboards: Thinnest Gherkin

40% Keyboards A blog about small mechanical keyboards. Home Firmware Parts Vendors corrects IE6 width calculation Thursday, February 22, 2018 This is the thinnest Gherkin I've made so far. Gherkin ML PCB with a bottom from the Gherkin Pack . 4mm M2 spacers. The board is 18mm from rubber bumpon feet to the top of the keycaps. The keycaps and switches were recycled from a Cherry G84-5500LPMEU-2 . The Cherry keycaps were designed to be used on an offset switch. The stems are not centered on the switch. They were also designed for 18mm switch spacing, instead of 19.05mm. This leaves a larger gap between the keys. Bottom piece from the Gherkin Pack . I usually use a second PCB for the bottom. 4mm ...

40% Keyboards: Lobot

40% Keyboards A blog about small mechanical keyboards. Home Firmware Parts Vendors corrects IE6 width calculation Monday, January 22, 2018 The Lobot is my third version of a Pro Micro ISP programmer. The first version used a Pro Micro running the Arduino ISP sketch. The second version was a Raspberry Pi 0 using it's GPIO pins. I use these to replace the Arduino caterina bootloader with the standard Atmel DFU bootloader. The caterina bootloader works fine when used with the Arduino IDE. It is automatic. However when being programmed outside of Arduino you have to manually deal with the reset timing which many people have problems with. The DFU bootloader is much simpler, once reset into bootloader m...

40% Keyboards

A blog about small mechanical keyboards. Home Firmware Parts Vendors corrects IE6 width calculation Monday, February 19, 2018 Lobot A-Star Micro Lobot The Lobot can also be used as an ISP programmer for the A-Star Micro from Pololu and the Arduino Micro clone . The A-Star Micro is used in the Atreus . I replaced the bootloader on the Atreus I built with the LUFA Mass Storage bootloader . It would have been a lot easier to flash the bootloader with the Lobot. The A-Star Micro is similar to the Pro Micro, but much smaller . It comes with the same Caterina type bootloader. The only change is that the pogo pins are installed in the 6 pin ISP header location. I took apart a pin header and built a...

40% Keyboards: 4x4x4x4x4

40% Keyboards A blog about small mechanical keyboards. Home Firmware Parts Vendors corrects IE6 width calculation Monday, January 8, 2018 The basic unit is a 4x4 matrix with 16 keys. Up to 4 of these can be connected to each other side by side. 4x4, 4x8, 4x12 and 4x16 are possible. There are pads for header pins on each side that complete the circuits from board to board. These can be permanently connected with solder bridges or with pin headers and shunt jumpers. The PCB is a perfect square. Exactly 3 inches square. Standard switch spacing is 0.75 inches, 19.05mm. The header pins are the common 0.1 inch spacing (2.54mm). The Gerber files are on github . The schematic shows how the header pi...

40% Keyboards: 16mm Jelly Comb

40% Keyboards A blog about small mechanical keyboards. Home Firmware Parts Vendors corrects IE6 width calculation Friday, May 12, 2017 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". Posted by kb Email This BlogThis! Shar...
