In this project, I converted an image of a hot air balloon into a dowel rod sculpture. The final structure is a transformation of digital information stored in a photo into a physical 3D object. I constructed the sculpture to help visualize how images are stored on computers, as well as demonstrate the enormous scale of information in just a single picture that you see on a computer. It looks cool too! This instructable will go through how to construct an image based dowel rod sculpture of your own.Here’s the basic idea. Every digital image is made up of many tiny squares (pixels) with each square assigned some intensity value. Very dark regions in the photo have pixels with low intensity values, while regions that are bright (e.g. the balloon) have high intensity values. In the sculpture, the intensity values at each pixel in the image are converted to
I saw one of these mirrors online and instantly set out to make one in the cheapest, thriftiest and easiest way I could find and now you can too! This mirror is my second iteration, I used a Laptop first to write the code and eased my way into using the Raspberry Pi, The total cost of the build was $146 NZD = roughly $100 USD I am using Raspberry Pi 3 model B for the brains of the project as it has built in WIFI which is perfect for this. Building this mirror was my first taste of the Pi, and it was delicious... If you like this instructable please vote for me in the Beyond the Comfort Zone or Internet of Things competitions :-) thaaank yoooou.You will need:(Expenses I paid in NZ Dollar) Raspberry Pi 3 (with power supply) - $70 Desktop Monitor (recommend 19" or larger)
EEGs are a noninvasive way to look into your brain. While the brain is extremely complex, areas of it can lock into circular firing patterns, resulting in telltale brain waves that one can observe with the right equipment. Intensity of these waves change depending on your internal state. The waves we will be most easily able to distinguish are alpha and beta waves -- alpha waves occur at around 8-12 Hz and when measured from the frontal lobe provide an estimate of how relaxed a person is, while beta waves are around 12-30 Hz and correspond to how much a person is concentrating or how alert they are. The concentration of each wave can also tell more specific things about your thought patterns depending on where you measure them from. For example, alpha concentrations on the left motor cortex increase when you think about moving your right hand. Regardless o
We love Electric Imp, its simplicity and how it works. This is the reason why this is the very first tutorial explaining with detail how to connect Electric Imp with thethings.iO. The ElectricImp + thethings.iO library that we implemented let you read, write and activate things through the REST API from thethings.iO. From now if …
