January 2020 STEAM Camp

Basic Course Narrative

• Day 1 - intro to OSE Collaborative Design for a transparent and inclusive economy of abundance. We culminate by building a 3D printer from scratch.
• Day 2 - Collaborative Design. We learn the toolchain from designing FreeCAD to 3D printed parts on our 3D Printers - in one hour. We design and 3D print a motor mount - to make an educational CNC mill for D3D Universal using a 555 motor. Then we learn how to bed level for CNC milling and how to design gcode manually or with a gcode generator, so we are ready to build a practical mill by making larger Universal Axes.
• Day 3 - Electronics. We then do CNC drilling of a hole pattern for a 28 pin chip - to make our own Arduino by hand drawing the rest of the circuit and etching on the D3D Universal Etcher (agitator of milling bath). We build a switching circuit to control a light or motor using this Arduino, learning basic programming with Arduino. We get more serious by starting to use KiCad to design a sample circuit, and to begin making 3D printed circuits with 3D printed terminals.
• Day 4 - We design and build stackable battery packs around the 18650 lithium batteries. We then build a cordless welder and battery charger, controlled by our home-made arduino.
• Day 5-9 - project days: Raspberry Pi Tablet film studio - see Raspberry Pi Tablet Specification.

More

• Etching - learning a g-code lesson
• Stick to 555 motor.

Day 1: ok Day 2: let's build a motor from scratch, but here's a simple one. Collaborative design of spindle holder. Hand_Drawn_Circuits. Later - plastic rotor with magnets glued in.
