Remember several posts looking for ways to add sound to some projects. 30 seconds for $2.00, seems like a very good deal. Bonus is that it's already wired up, not just a chip. Haven't order any yet, but thinking about getting a few.

Harvey, please let me know how they sound. I will get a couple for little one time projects. Golf cart reverse voice, etc.

One problem, the $2 unit will have a shipping cost, so you might want to search their catalog for other items.

I have bought from them before. They are a surplus company. So they might be OK and it was just a bad movie and they did not sell.

Or, they might be junk. I would not expect great quality from them for sure.

I order 10 of them, a 12 volt SLA & charger, and a few other odds and ends. Should be here late next week.

I've ordered from them many times, some stuff can be found cheaper, sometimes there are some great deals. Usually try to look through the new stuff weekly.

I don't anticipate that it will play back very loud off 2 AAA batteries, can only hope it retains the recording after the power is removed. Considering the size, expect the 'speaker' to be a thin piezo beeper type, and likely just good enough for voice.

I'm planning on gutting them anyway for other projects, so adding a simple transistor amplifier or LM386 won't be a big deal. Thinking these will match up nicely with my IR proximity detector.

Will keep you all posted, guessing they have a huge quantity, since they didn't post a limit, and give a discount on 10 or more.

Edit: Hoping the little plastic figure is of the softer plastic type, dog toys...

Hmmm... Maybe that's why these are surplus.

Jake's a Labrador, he has eaten some pretty weird and potential hazardous stuff, some I know got swallowed, from what he left the following day... Mostly, he just chews things up into little bits for me to clean up after work. Fortunately, he's been focusing on paper products this past month. Forgot to close the bathroom door Friday, whole roll of toilet paper shredded and distributed throughout the house. Must have been a real treat for him...

I really don't give him junk like that to chew up, well lots of old shoes... But usually, I try to limit him to normal toys. I don't want him to think it's okay to chew on just anything that catches his interest. If they are consistent with materials in his other toys, maybe...

Really not expecting high quality sound from these things, just a reasonable reproduction. Most likely the PCB will have a large black blob in the middle. Not too bad, as the board has to be less than 2.5 inches square. Might not be worth worrying about a electret, as the sample rate will most likely be low.
Just have to wait a week, to see if I scored a good deal, or some barely usable junk, closest I get to gambling...

Please let us know if they are useful to modify or just an ASIC semiconductor IC die in an epoxy blob on a PCB.

I need a circuit that will record about a second, then immediately play back at double or quadruple speed, then repeat this sequence over and over in order to hear infrasonic frequencies in the 5-60Hz region.

Been held hostage all day waiting on the UPS guy. Tracking says its been out for delivery since 5:48 AM, about 4:30 PM now... Least I had another project to keep me busy. They deliver until 7 PM, so still a chance I'll get to play around with them this weekend.
