Vocal Willow, an affordable, audio-first attachable sensor system designed to enable blind and visually impaired cricketers,PaddleBall and PickleBall players to practice independently. This project leverages affordable hardware and rule-based edge computing to bridge the independence gap in blind sports. Besides that it can also function as a performance tracker for well-fit people! Collaborator:- Svix_19
been busy for the past two days, gonna get active again from today.
anyways i printed the new case and it fitted fine.Now i need to figure out a way to cancel out the ground data so that it only detects ball impact.
Made Changes in the case to fit 18650 li ion batteries and tuned the code so that it accurately detects hit/miss (doesnot show in between like weak shot or edge etc)
so today will supposedly stress testing the v2 i kept it on idle for 20 mins and it blacked out after that so i immediately unplugged everything and i tried charging the battery using tp4-56 module but it also got very hot so i removed all the battery wires and turns out the tp4056 module was fried because of overdischarge (i was using 3.7 v lipo battery with v2 instead of 3.7 li ion 18650 in the v1). After some diagnostics i found out that it occurred because of thermal problems so for now i have to redesign the case to fit a 18650 because it is more reliable. Also added some zipties
What have i been upto?
I finished with the V1 3 days ago although i didnt record it, it was very bulky because of the expansion board and 18650 batteries so i set onto making the v2 much smaller and less bulky which meant removing the expansion board and using a much smaller battery. also in V1 i used the buck converter for 7v to 5v but this time in v2 i used a single 3.7v lipo battery and boosted it to 5v to save space. the code data is still very inaccurate ill be working on it soon. I also posted a lapse of me redesigning the v2 case because i forgot to add a hole to easily update the code without taking the whole thing apart everytime.
Today i started working on the V1 of my sports for blind people project, with some help from claude for figuring out how to turn the data from the sensors to useful information which will be shown at a local website for now (will write an android app and ios app for it later).
V1 is supposed to be the testing phase in which ill focus on perfecting the data and accuracy ignoring the bulkiness of the project for now.
