You will hack together a digital bathroom scale (strain gauge), to a circuit board that will play musical notes through a speaker as pre-programmed weight targets of the scale are reached, in real time, as a person's weight begins loading the scale. You will figure out and write code that programs the notes to sound, based on an incremental weight schedule. Component requirements must be discussed verbally. Must have circuit board and software/programming skills. Successful engagement will looks like this: We verbally discuss the requirements, components, and objective. The system is built and tested by you so that the objective is met. If I can't replicate it, you will ship the system to me; I pay for shipping. And finally, you will verbally help me understand how to edit the code to change variables and outcomes. The right freelancer for this job enjoys hacking this kind of project together and will appreciate that the end result is working to help improve the lives of amputees. He/She also knows how to choose proper componentry for requirements, and knows how to integrate high quality music notes with the board, but as to reduce the latency between when a weight target is met to how much time it takes the music note to sound. Please include in your application why you are ideal for this job, circuit board suggestions, software suggestions, limitations, and a time frame you can accomplish this job.
