+# redScorpe's Numpad
+
+This is my custom version of a simple numpad with a Rotary Encoder and a 9.1" OLED-Display. Since I have recently switched to a TKL-Keyboard to easier switch between mouse and keyboard I wondered how cool it would be to have an external numpad which also has a rotary which my new keyboard is missing.
+
+# Challenges
+I was genuinely confused about a lot things regarding the whole process of building my first hackpad since all of this was new to me. However making my own symbol in KiCad for the OLED directly at the start of this journey was honestly the most challenging part for me.
