+This week I spent a good amount of time getting much more familiar with [KiCAD](https://www.kicad.org/) which, as they say on their website, is a *electronics design suite*. Basically **[in dumb guy language]**, its just a bunch of programs that help with the design of *PCBs* or *printed circuit boards* **[you know, the green boards that you find inside stuff, like [this](https://upload.wikimedia.org/wikipedia/commons/9/90/PCB_design.jpg)]**.
+
+The goal at the moment is to *design* and *fabricate* a *PCB* completely in house. This means coming up with a purpose **[what? you don't just start a project despite not really having a purpose for doing it?]**, designing the circuit, laying it out on a board, and then actually yanking that design into reality.
+
+Just a quick rundown 
+
+- create a design in *KiCAD*, both the schematic layout and the PCB layout
+- 
+
+
+Overview
+- Learning KiCAD
+- Design a PCB
+    - What purpose
+    - Start with hard
+- Fabricate the PCB
+    - Toner transfer method
+    - Some chemistry
+    - Safety is important
+Kicad
+    - The Schematic Workflow
+        - Knowing design
+        - Use other software?
+            -XCircuit and NGSPICE
+        - Endgoal get schematic
+        - Recreate schematic in KiCAD
+        - Think all the same if schematic is had
+        - What are power flags?
+        - Make sure nets are all labled for easy layout design
+        - Check things with the ERC
+        - Add Comments just like in Programming
+        - Associate the PCB footprints with components
+    - The PCB Workflow
+        - Create the shape and size
+            - Does everything fit?
+            - Are the components reasonable
+        - Place and Route
+            - Put footprints with user and routing in mind
+            - Route, Most time consuming I think
+        - Add annotations  to the board with silkscreen
+        - Check stuff with DRC
+
+Fabrication
+- Toner transfer method
+- Print Cu layer on magazine
+- Place on Cuclad sheet. Acetone on back to tranfer. then dry
+- wipe with water
+- put in etchent - now is Feric Chloride
+- wipe with water
+- put uv ink on
+- put transparent screen with solder points covered
+- smoosh uv ink. put in uv oven
+- take out of oven and remove transparent
+- wipe of uv ink. dots should go everthing else stays
+- do the same uv ink process for silk screen
+- invert text. print smoosh, uv oven, wipe off all the rest
