The objective is to design a power meter which displays two types of data: the status of the battery and the power generated by volunteers for the Flock House. The display must be clearly visible from at least 20 feet and be visually appealing to the public.
Solar Suitcase1.jpg
A project where Humboldt State University (HSU) students obtained a solar suitcase from the non-profit We Share Solar. The solar suitcase is a portable, small scale solar system. These students constructed and tested the solar suitcase then gave a presentation and taught a class of college students how to build this solar suitcase and test it in a learning environment. The purpose of these solar suitcases is to provide electricity to rural/poor locations in the world. After the construction of small and larger solar suitcases for this project, some were sent to developing countries to provide some citizens with electricity.

These jigs are used to make holes to join together pieces of wood in products such as tables, clocks, nightstands, or any fine finished wood product.
Students from Humboldt State University that were part of the Practivistas Dominicanas program traveled to a city called La Yuca in Santo Domingo, Dominican Republic. This group of students built a solar power system for a school there that allows the school to run lights and fans and function when there is a power outage in the area as well.
The objective is to fix the ecoladrillo schoolroom by adding a new plaster to the walls, fixing the floor, and fixing the ventilation of the room using natural building techniques.
Provide Laurel Tree Charter School with an energy monitoring system that shows energy consumption in a way that was both interesting and understandable to students of all ages.
The human powered blender is a device intended to be used by students in grades K-12 at Laurel Tree Charter School in Arcata, California. The device will blend food in the school's cafeteria, while teaching students about alternate methods of energy production.
The objective of the Current Specialists was to design, build and implement a learning apparatus to teach the difference between series and parallel wiring. The device was required to include an element of mystery while catering to grades 7-12.
The purpose of this project is to create a low embedded energy, natural, beautiful way to cook pizza.
Manual Centrifuge Apparatus is a scientific equipment which is widely used in chemical and clinical labs all around the world. This apparatus is used to separate two fluids with different densities when rotated at very high speeds.
OSAT Monochromator.jpg
A monochromator is a device which takes light and transmits it to into a narrow band of wavelengths. Using a form of mechanical filtering (diffraction) the user is able to select a specific wavelength (color) which would exit through a exit slit. The monochromator holds many scientific applications ranging from measuring a reflected or transmitted light off a surface.
First, this will be useful in education, where protractors can be used to help teach geometric concepts. Additionally, they can be used in construction to make sure angle measurements are made accurately.
The combination of open-source software and hardware provide technically feasible methods to create low-cost, highly-customized scientific research equipment.

This page describes what photovoltaics is, how it works, the different components necessary in a photovoltaic system and their importances, the advancements of photovoltaic technology and pros and cons associated with photovoltaics.
The purpose of this project is to replace the current play structure at the Redwood Coast Montessori School (RCMS) and the Manila Community Center, located in Manila, CA. Redwood Coast Montessori is a school with 80 students that range from Kindergarten-Six grade.
LasCalabazas ChargingStation.jpg
The objective is to implement a functional solar powered system that educates the students and staff of Redwood Coast Montessori, as well as the public, of solar power, solar panels, and the importance of solar as a renewable energy.
Track pretotype.png
The objective of this project is to design and build a functional Brachistochrone exhibit and present the concept in a fun and educational method; while maintaining a sturdy, child-safe structure that is both aesthetically pleasing and engaging.
Tinker Desk final.jpg
The desk must be sturdy and include a large work surface to accommodate various art projects. The inclusion of up-cycled materials in the base design of the desk was mandatory for this assignment.
This Open Source 3D sample rotator accepts a variety of tube sizes and mixes them horizontally, vertically, or any position in between. Changing the mixing angle is easy simply turn the rotisserie. No tools are required.

Solar energy has many uses such as electricity production and heating. There are many projects described on appropedia that show examples of heating water, dehydrating food, producing electricity with solar panels, building solar cookers and other inventive solar devices, among many more projects. There are numerous benefits to solar energy in any form that include supporting a renewable energy source, reducing electricity bills, rebates, and advancement of photovoltaic technology.
