This was the test done in the kitchen but I have video from a few days ago with a bunch of EVP sessions done at the Grave/memorial stone where the owner of the cottage burned himself to death in his mini-van, still going through the audio recordings and video, was a successful investigation, in the night we had bad thunderstorms and only got the day time footage. EZ Robot system performing Excellent outdoors ,I just need to make the script available for my cell phone in the EZ mobile phone app. Having trouble with ultrasonic conversion, I need to add the ping command to the current laptop script for it to work on mobile phone. I will add the current script for public anyone to use if they have a tank/H-bridge and ultrasonic sonar robot. Please add your own improvements modifications, I am learning something new everyday with the scripting but still new to it!
