/diy/ - Do It Yourself

ok so /ohm/ so here's what i'm working on. I have this good friend who may suffer from mild auditory hallucinations and I'm kind of an asshole so what i've done bought ISD1820 audio recording IC thing holds 10 sec of audio fair quality and has built in amp. So i'm waiting on some vibration sensor units from fleabay. and what i'm going to do is program a pic so that if the sensors vibrate at a certain threshold this will set up a timer that will randomly select a time period from 30 secs to 3 minutes after which it will trigger the chip. The audio track is non selectable but after waiting enough time for the desired segment to play (also randomly selected from three creepy sound clips. mr food's oh it's so good, crying baby, random segment from baptist preacher) that PIC will also turn on the speaker.

I'm using a small laptop speaker and powering the whole unit from 3 button cells. My plan is to wait to i'm at his house and sneak into his room take his pillow out of case cut open his pillow and insert the device into the cotton tape it back up with fabric tape slip the cover back over it. The whole thing runs in low power mode after not being triggered for awhile and draws only pico amps so it will last awhile.

i think it be brutty gud'
