Thread: "Sound bricks" with 20sec playback

Tweet

I have found a great little sound recorder that has 20-21 sec of record & playback.
It has a control for sensitivity of motion sensor,a volume control. I bought 2 of these
to try out & was so impressed with them that i bought several more. It has a speaker
that with the volume control,you can hear it very well !! They are on EBay &
the seller is fast on shipping & communication.They were $6. plus a flat $2.25 shipping.
Of all the sound recorders i have seen & tried this lil guy is worth it.He is doing
bids starting now at $8. Sells/bids them on a 20 lot dutch auction,but always seems
to never sell more than 20 at a time,so i get them at the begining bid or a .50-$1. more,
but still worth it.They have a 6ft motion sensor range........but could be hacked to a trigger.....?
has an inlet for a plug 110ac adapter but he doesn't have them or know what ac-dc power adapter it uses,
but runs off 4 aa batts. If you are looking for a sound recorder/play back for a prop or even hide it
& as someone goes by it goes off with whatever...........
These are new & auction ends he always has another 20 up for sale.Not sure how many of these they have left.....& he is near me,SF bay area,vacaville/Benica

Pretty handy. How's the sound quality? I don't see any reason why this couldn't be modified with a speaker jack so you could amplify the sound. Connecting a trigger (better motion sensor, pressure mat, etc.) should be easy as well.

Thanks for the tip!

I was actually impressed by the little speaker that it has.Clear & loud enough,but i am sure it can be re-speakered.
I've bought a few out there & they are $20.. plus shipping,or crappy speaker & 10 sec record playback, I like that this has volume &
sensor control & that i can hear it from a decent distance ! & this is the reason i want to pass this on as we seem to have a lack of
stand alone recorders with a trigger for a hear-able playback that is AFFORDABLE for the haunter on a budget & with 20-21 sec of recordabillty.

That's a pretty good deal...

May have to pick up one of those. Thanks!

Beware, in very low light conditions, I found mine to be somewhat unresponsive. If you aim a light or LED at the sensor, the shadow of the person in front of mine set it off fine. Dark Lord, try yours out in the dark and let us know what you find. Hope this is just a problem with mine.

No it is not yours,they are motion sensored,not pir. But someone on another halloween forum remembers these out a few years ago & never heard bad about them
& that there were some that had modified them for remote (mat,etc) activating & redoing them with pirs.... come on here,the home of "lets tweek it" someone here
has proven that 99 percent of the time anything can be rerigged !!
I placed a light (red or blue works) as ambient lighting,just enough so that when someone walks by it,it triggers.

did you get your from this guy on EBay ? or else where ?

Got mine a couple years ago. Works really well. Used it to make my owl "hoot". The name of the seller doesn't ring a bell, but they were about the same price back then.

I've been messing with mine for about a week. The light sensor is pretty poor for Halloween use. It needs a light source to be broken to trigger. Still, it's very handy.

I modified one last night. I added an external speaker jack and disconnected the CdS sensor. I ran the sensor wires to an external jack which connects to a relay on a prop controller I built. Instant sound effect when I need it! Solved a lot of problems for me on this particular prop.

ive got a couple of these sound devices also. the CDS sensor doesnt work in the dark at all. Here is what i want to do. if anyone can help let me know if this is possible and simple. i got a paralax PIR from radio Shack. cant i just remove the CDS and solder on the PIR? if so i dont know what to connect to what. ther are 3 pins on the pir. (-) grd, + and signal. the CDS sensor on has a pair a wire leads to it. i guess + & -. i tried it but didnt get any result. maybe i didnt let it activate long enough? Also there is a jumper for hi lo. not sure hat that is for? any help? I want to make this work without programming and more complicated controllers. thanks!
