I had Aliexpress in my mind because I order much stuff there, but it was wrong. If a high shear mixer works, that would open the door for many more people, as they are not as expensive as Ultrasonic I looked into my orders on Aliexpress and realized that I ordered it in Germany from a Company called Vevor. You could first order a cheap high shear mixer and try it out and if it doesnt work send it back and then order a Ultrasonic probe. High shear mixers like mentioned above (if they work) are much cheaper and are available easily on Ebay and Amazon. I ordered my ultrasonic probe on Aliexpress, but maybe you also find a used one for cheap. Maybe 0.1 to 0.5 grams for a big 100 x 50 cm epoxy sheet. I ordered 50 Grams and I have plenty left. I live in germany and I think shipping to Great Britain will not be a big problem. If you are willing to buy a machine for dispersion I can also send you some of the nanoparticles for free. online till I understood all this stuff □ You can believe me if I say I read 100 of websites about chemistry and nano particles dispersion etc. They also need to be hydrophobized which means they are compatible with epoxy. The Titanium Dioxide nanoparticles which I have here are about 21 Nanometer and work perfectly. These nanoparticles have to be separated from each other which is called dispersion.Īnd this is what these machines do, they separat the cluster of particles in individual particles. The thing is, that nanoparticles always stick together when you order them, it is called agglomerates. To discuss this project and help develop it, or request help yourself in building it, feel free to discuss! However, it's a topic that will be revisited in the future so stay tuned. In the case of the video this is achieved using soap, but there are other methods that will be explored in a future episode.Īs this project is very much a prototype, there is no written guide or files for it. This makes the LED light appear to be at infinity when viewed bouncing off the satellite dish, and results in shadows cast from it being parallel, for example.Īs for the blue sky effect, that's produced by passing the light through a light scattering medium. By inverting this process and making the satellite dish reflective to lightwaves, it's possible to emit parallel light rays from it by installing a bright LED at its focal point instead. Satellite dishes work by reflecting distant radio waves to a single point, as they're usually a section of a parabola (shape). The backbone of how this project works is an old satellite dish. The goal of this project was to recreate some of the unique characteristics of sunlight, namely that the sun itself is practically at infinity, and that the atmosphere scatters some of its blue light resulting in the blue sky we're all familiar with.
