fast documentation of hardware and software projects
So I may have gotten a bit carried away before with the whole egg thing. Tried building a working prototype without first doing some experimentation to make sure it is possible to tell how boiled an egg is by using sound waves. I’ve gone back to the basics and done some experimentation. The results are…
Code used for microcontroller: The uC used was a pic18f14k50. Code compiled using xc8 compilter. Read analog channel function taken from batchloaf’s template code post. Here is the source code:
The idea: The smart trolley idea is my final year college project that I have been working on for the past two and a half months. The idea is that in every supermarket all of the products have small RFID tags stuck on them. The trolleys will have an antenna built in, alongside an RFID…
Sound triangulation is a method of determining where a sound originated from. Triangulation can give the location of a sound source in 2-d space. A sound wave travels out from its point of origin as a sphere. Trilateration is another method a locating the source of a sound. It is modeled around the fact that…
