I am looking to build a simple voice recorder without using a microcontroller. I googled for it like 10 min, but i cannot come up with a voice reccorder that doesnt use a microcontroller. If it is not possible, is there a microcontroller with the program already installed/specialized chip with no programming required? The sound quality does not have to be good, but i need it for busting sombody for lying and for taking notes. also, if possible how could i reset it?

Would i use a EEPROM to store this memory/voice thing?

What is its name/ mfg number?
Maybe we could relay stuff back and forth, aka email?

As opposed to the forum, that way we wont fill this up

the mfg number is isd1110p. you can go to winbondusa and download the pdf. its under chipcorder. it has a schematic of how to hook it up. i made a recorder a playback board that loops with an edge trigger. there are different ways you can use it though.

Cool. I found the 1110p for 3$. I am going to buy one, but can you delete the reccording?

Perhaps you might try reading the datasheet?.
