  • With a little soldering experience I found the phantom easy to build (https://www.youtube.com/watch?v=gdLAdci6p-w is a good tutorial), and got a great TKL keyboard out of it. Fully programmable thanks to QMK firmware. Fit perfectly into the case of my old KBParadise V80 after cutting one plastic nub from the case.

    Pros:
    easy to build with a little soldering experience. No SMD soldering required.
    free/open-source firmware available (https://qmk.fm)
    fully programmable thanks to firmware
    lots of layout options available

    Cons:
    - Teensy 2.0 MCU feels a little dated (little memory to flash bigger firmware builds onto)
    - All pins on the Teensy are required for the keyboard matrix and the 2 LEDs, so there are no free pins remaining and it's practically impossible to add extra hardware features like OLED displays or rotary encoders. Since I wanted audible feedback, I had to add a piezo speaker in parallel to the scroll lock LED and had to program around the limitations as best I could.

  • Awesome if you're into custom keyboards. This one is a bit of a challenge, but if you're up for it it's a great project to challenge yourself and build a beautiful custom keyboard.
    I accidentally destroyed the PCB on a KUL ES-87. Using this PCB I was able to recover the switches (clears) and re-use the case.
    On the way I learned a lot about soldering diodes and teensy's and flashing QMK onto them. BTW, this thing runs QMK just great.
