+# poler1_KB
+
+- This is a keyboard totally built from scratch and has anti ghosting 68 switches with a bunch of RGB and a display controlled by a knob.
+
+---
+
+## Inspiration
+
+My inspiration for this keyboard is the wooting keyboard but due to my amateur routing techniques i had to come up with a slightly bigger keyboard than the original wooting keyboard but in return I added a display and a knob to show animations and probably change animations shown on the display.
+
+## Challenges
+
+I have no clue how I have managed to build the case for it. It was extremely challenging because I dont have the physical board to measure. I managed to build a really simple design which protects the base of PCB and also avoid the damage incase of a drop lol.
