The presented treatment unit serves as a means to reduce turbidity in water to be subsequently treated with solar water disinfection (SODIS) technology. The unit is comprised of a well-graded sand filter through which turbid water flows and subsequently settles.
OPURDew Roof.jpg
This work offers a primer to the topic of AWVPs, and a description of how to build a dew collection rig. Unfortunately, dewfall is not currently recorded in most standard meteorological archives; so the next step for this project is to offer a reliable means of regional assessment that is accessible to a layman.
Relief Platform 1.jpg
Simple and easy to produce, temporary housing platform to to aid in living conditions after a natural disaster
Drop spindle.jpg
The Drop Spindle is an ancient tool used for spinning fibers such as wool, cotton, flax, and hemp into yarn, without the need for a large, expensive, and complex spinning wheel. This a 3D printable drop spindle.
Fieldready ECG 2.JPG
The design fulfills the need for a cheap single 3D print that will function as a ECG limb lead holder.
Neb.png
A nebuliser works by using compressed air to convert liquid medicine to an aerosol that can be inhaled by the patient. This is a 3D printable design
Nebuliser Connector Finished.JPG
The reason this design challenge was created was to replace a poorly designed connector for an air hose on a nebuliser. The current fitting often snaps off under normal use and requires a significant amount of effort every several days to re-glue the undersized fitting back on.
Garden Rip and Seeder.jpeg
This project was originally intended for the developing world to aid in farming and rapid planting.

This 3D printable device is a portable, easy to use unit that uses a limited amount of water. Could help prevent spread of sicknesses in a village or house without access to running water.
Hand Wood Planer.jpg
The hand wood planer is designed for making medium to detailed design cuts on wood.
FullCrutch 4.jpg
This Open Source Appropriate Technology (OSAT) aims to decrease the overall cost of a standard crutch and to enter the specialized market.
Biodigester cross section AA.JPG
The design of most biogas systems can be traced to either the China Fixed Dome (CFD) 6+ million in-use or the India Floating Cover (IFC) 2.9+ million in-use. The Philippine BioDigester Home Biogas System (HBS) is a product of both designs.
Layucafirstflush2014.jpg
Our objective for the water project for the 2014 Practivistas Dominicana Program in La Yuca is to replace the flat piping system, used to catch rainwater runoff from the roof, with a gutter that will obtain more water.
No image.svg
The objective for this project is to build a small local pharmacy (Botica Popular) for the people of Las Malvinas, which will provide basic medical supplies and medications to the community at a much lower cost.
LTCSGreenLightDemo.jpg
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.
LTCSHumanPowerBlenderDemo.jpg
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.
Onderdonksbox.JPG
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.

Snaps can be used in a variety of ways; shirts, coats, satchels or bags, or any other system that would be desired to hold together. This simple idea of a snap system and the varities of of uses make this an aopporiate OSAT project.
Honeycow.jpg
The Honey Cow is designed to mimic nature as much as possible.
CentrifugeApparatus.jpg
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.

This project is for greywater usage and may not meet clean drinking water standards. (not potable water)
Measuringcup1.jpg
The openscad project is set to print a 1 cup measuring cup, but can be easily scaled to any practical size for cooking.
Jcpaulse OSATproject.jpg
The mineral sifter is an excellent example of OSAT. Sifters are a major time saver, especially in developing countries where simple appliances are difficult to come by. This sifter can be used in a variety of different ways ranging from cooking to gardening.
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.

The treadle pump is a lift pump designed to irrigate small plots of land. Treadle pumps are designed to be operated by the farmer or hand in a "stair stepper" type motion to lift water from a depth of not over seven meters.
Teshawar infantometer.jpeg
Proper growth of infants and young children is paramount to the development of well-functioning adults. Infantometers can be used to measure the height of infants and small children to gauge the physical growth during the early stages of life.
Jchamilt OSAT.PNG
This toilet paper holder is an appropriate technology because it allows people in developing countries to store and use their toilet paper cleanly. The pole can be used to store rolls of toilet paper vertically, and then the actual holder on top will hold the toilet paper as it is dispensed.
RopePumpValvePIC.jpg
Rope pumps are an incredibly easy and cost effective way of raising water to the surface. The main hindrance is the valves that go on the rope. This 3D design cuts down production materials, energy and cost.

Nitrate, the most oxidized form of nitrogen, is regulated to protect people and animals from harmful levels as there is a large over abundance due to anthropogenic factors. The leading certified method to detect and quantify nitrate, demands the use of a toxic heavy metal. An alternative eliminates this problem but requires an expensive proprietary spectrophotometer. The development of an inexpensive portable, handheld photometer will greatly expedite field nitrate analysis to combat pollution.
RepRapsci.jpg
The combination of open-source software and hardware provide technically feasible methods to create low-cost, highly-customized scientific research equipment.
2 OSHE Extruder 12 13 2016.jpg

2sbms garden.jpg
Building a garden at Sunny Brae Middle School is one step towards creating an experiential learning facility designed to educate middle school kids about sustainable agriculture
Toiletpaperholder.jpg
This is a helpful OSAT project because it will help anyone in the developing world keep any toilet paper off the ground where it could potentially get wet or dirty therefore this is a more sanitary and will waste less toilet paper.
Aquaponic System.jpg
The WetLand project’s mission is to present the world of water and wetlands by constructing an island-based ecosystem that acts as a mobile habitat floating on the Delaware River in Philadelphia. The floating barge will be open to the public to educate people about sustainable uses of resources and about water-based ecosystems.
