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 - Get the printer. Collaborative Design. We learn the toolchain from designing FreeCAD to 3D printed parts on our 3D Printers - in one hour. Couple of quick useful prints - hacksaw or allan key holder. 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 2 is Collaborative Design. Just design and iterate and get
- 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. Breadboard example. Combine the techniques to make it useful. Include 3d printed Power Board - [1]
We take DIY arduino, CNC holes, hand etching, stripboard. Connect stripboard to KiCad lesson. Stripboard shield for Arduino. https://startingelectronics.org/projects/arduino-projects/arduino-tiny-stripboard-shield/
- 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.
Weld 2 8 mm rods together.
- Day 5-9 - project days: Raspberry Pi Tablet film studio - see Raspberry Pi Tablet Specification.

- 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. In future, need to go to 3 phase motor, which is self-starting. You can also determine which direction it turns.
Chris likes circuits by hang. Doable, for DIY arduino
Build your own UA, built you own spindle, designed spindle holder, generated gcode, cnc drilled, drew your circuit, put it in a bath and etch, agitate with ecofluid on the UA. Solder. get a working arduino Uno.
