January 2020 STEAM Camp Developer Kit

Microfactory Prototyping and Developer Kit

As part of the STEAM Camp, each participant will receive a Developer Kit consisting of the following parts - to take home with them. We will build all these parts into useful products or experiments, and these constitute a set of important building blocks for teaching, which can be extended into economic productivity.

1. 3D Printer - D3D Universal 3D printer kit - with automated bed leveling, quick release spring steel print bed, automated bed leveling, volcano nozzle for fast printing, and fast 1.2 mm stock printing nozzle. We include a spool of filament and a set of small tools required to put the printer together. Our printer is modular, highly expandable, and features the lowest part count of any 3D printer that we know of. It is made for expandability and bootstrapping to industrial grade machines - yet it features a simple design made from common off-the-shelf parts - thus allowing a lifetime of service and the ability to grow the machine as your production needs grow. The 3D Printer includes an SD card of printing files to make the D3D Pro 3D Printer and the CNC Torch Table.
2. Plotter Attachment Kit - a pen plotter attachment is included in the kit, which is mounted on D3D Universal as a separate, quick-attach toolhead for CNC plotting of pictures or for drawing circuits to be etched on copper-clad boards. The plotter attachments includes a pen.
3. Milling Attachment Kit - the milling attachment kit includes a DC motor, coupler, and 1 mm milling bit, and quick-attach mount for mounting the motor to the D3D Universal CNC axis.
4. Electronics Kit - This includes the parts necessary to build 2 Arduino Uno microcontrollers from scratch: components, strip board, copper clad board, soldering iron, copper chloride etchant, and a bath container for mounting on the D3D Unviversal bed for agitation. Combined with the Milling Attachment Kit, Battery and Welder Kit, and a KiCad lesson, this constitutes a rich lesson plan on circuit-making for practical purposes.
5. Battery and Welder Kit - this includes all the parts necessary to build a battery pack from 18650 lithium ion cells, and a 3D printed welder Power Controller Board that can be powered by a stack of battery packs. Each kit contains 6 of the lithium ion cells, so we will combine multiple battery packs from several participants into a larger power pack to make a functional, 60-180 amp welder. We will build a simple welding electrode holder and 3D printed clamp - and we are ready for a welding lesson. The same Power Controller Board that we are using for the welder is a generalized Power Electronics Circuit can be modified to function as a light dimmer, DC motor power supply, and battery charger - and is controlled by the Arduino from the Electronics Kit.
6. Raspberry Pi Tablet and Film Studio Kit - comes with a Raspberry Pi 4B, 7" touch LCD, a 4K Camera Module v2 for video, and LED module as a warm camera or shop light. Kit includes connection wiring and a battery charger. Together with the battery packs of the Battery and Welder Kit, this is ready to be turned into a functional multipurpose tablet - with 3d printed tripod, camera stabilizer, light, and slider.
