![]() Open the control program (ArduinoCode >Helios_2013) to set the time and location of the Heliostat, and to upload the program onto the Arduino.ġ) Choose whether you want Helios to act like a solar panel and track the sun (set the variable heliostat=0) or a heliostat (set the variable heliostat=1)Ī. I've also entered this instructable in the Tech and the Teach It contests. ![]() My next goal is to build a kayak from laser cut plywood that is reinforced with carbon fiber or glass fiber, as well as a cardboard surf board that is wrapped in structural fiber. An Epliog Laser would also allow me to build more interesting things and write more cool Instructables, such as this one about a Kayak that I refurbished. We hope that users will improve the design and continue to evolve Helios into a more effective learning tool.Įpilog Challenge VIAn Epilog Zing 16 Laser would allow me to complete higher quality projects,, and increase the amount of impact that I have with them.build interesting large scale things, and to tinker more effectively in general. Users have full rights to reproduce and improve on what we have done, as long as they continue to do so under the same license. Because this is our main focus, our work is licensed under the GNU FDL license. The goal of Helios is to promote engineering education. These design choices, along with a few other considerations, make the presented design a durable and affordable, educational tool. Additionally, the shaft that is attached to the mirror is powered through a timing belt, which allows for a small alignment error between the motor and the mirror, the servo motors are accurate to within 1 degree, and the platform runs on the open source Arduino platform. ![]() ![]() This was done to take advantage of foam core’s strength in tension and compression, and because the adhesive that was used is more effective at supporting a load in tension than in bending. Also, for maximum strength and rigidity, care was taken to design the body so that all of the foam parts are either in tension or compression. The first design choice was to build the body almost entirely out of foam core, which is rigid, affordable, easy to acquire, and easy to cut. To ensure that this project is widely dispersed, considerable effort went into designing the Helios to be built with common tools and cheap materials. An Arduino micro-controller will be used to run the program and control the two servo motors. The mechanism will track the sun by using a program to calculate the star’s location in the sky thought the day, based on the global position of the Helios. The physical structure of Helios’s design, as with other heliostat designs, functions to mount a mirror onto two controllable axes. In addition to the number of uses of this technology, there is also a diverse range of structures that have been designed to enable solar tracking. ![]() Such a device can be used for many applications, from concentrating solar energy onto the heat reservoir of a power plant to illuminating areas that are blocked from the sun. One option for greener energy is to use a device called a heliostat, which uses a mirror to direct the sun’s light onto a target throughout the day. There is an effort in engineering to push energy generation away from the use of fossil fuels and towards greener alternatives. We aim to introduce young students to engineering and teach them about solar energy by having them build a Helios as part of their curriculum. ![]()
