List of Available Classes

MassMind Classes (from easy to advanced)

*note: Class presentations are open source, and you are free to copy and use them. We can provide an instructor to present these classes online and help you collect the materials at your location after hours or weekends. Prices reflect materials cost only. No instructor cost if at least 10 students attend. More individual instruction to be negotiated.

Plastics casting with 3D printed molds. Mold your own glowing heart, skull, etc... from natural, reusable, low temp thermoplastic; light it up with an LED and coin battery. Learn to quickly form multiple objects from low cost molds. Pictures. $3 (10 K-12 and up) Combines nicely with Electronics Intro class as the throwie can light up the cast object making it a "Glowie". We can also teach mold making with Oogoo (a low cost rubber based on hardware store 100% silicone caulk mixed with half as much corn starch and a little paint). Or you can cast with Oogoo from a 3D printed mold. 20160107,

Cardboard Combat Robots with the ESP-8266. Ultra low cost (~$15) robot, controled via WiFi connection from your smart phone with a built in Web server, and Javascript based GUI. Part 1, 2, and 3. To avoid the Arduino IDE setup (parts 1 and 3), and the soldering (part 2) you can also just purchase the Boffinboard from Addicore.com.
Raspberry Pi Intro - Connect and program your Raspberry Pi computer - $0 without the RasPi, $80 for a Model B w/ power supply, wifi, case, cables. ^. NOT including monitor, keyboard, mouse. Venue must have wifi with accessble router. (10 senior high school and up)
Introduction to 3D printing - how to take a design file (.STL) and slice it for printing including printer tuning and troubleshooting. (10 high school and up) The 3D printed object can then be used to make an Oogoo mold for quick reproduction of additional copies in thermoplastic, epoxy, or other riged plastics. Or you can 3D print the mold directly and cast with Oogoo^, or other flexible materials. To make metal parts, print a positive in PLA, make a mold from plaster^ or casting sand, and poor in molten metal to burn away the plastic, or make a two part mold and remove the original before casting.
Introduction to OpenSCAD - Coding Reality: Basics of designing real physical objects with a programming language. $0 (20 senior high school and up).

For a more traditional CAD system see FreeCad
Introduction to G-Code for 3D Printing - Advanced class in how G-Code controls 3D printers, what the codes mean, and how to write custom G-Code for tricks! $0 (10 senior high school and up)
Motion control - Connect your computer to the real world and make it move with servos and stepper motors. $50 (10 senior high school and up)
JavaScript Programming Completely free online class. See also Internet: Web / HTML / Javascript* / IOT Intro (a less complex class)
Using GIT version control and using the GitHub web interface.

- Tips and Tricks
- Measurement Errors - How to make them... or not.
- Signal Noise - A very common problem.
- Extra, unused pins
- The Read, Modify, Write mistake
Advanced robotics with JavaScript Available online via Github repo with instructor feedback through raising Issues. Access to some robotic systems will depend on local purchase of supplies. In most cases, simulations can be used instead.
