Super Cute DIY Mini Audio Cartridges!
Added 2018-11-17 01:07:52 +0000 UTCLike Candy! But don't try to eat them! I side track a project I'm working on to highlight a component that no one would see otherwise - my own tiny removable programmable mini audio cartridges that can hold 20 second sound clips. It just seemed like it would be a cool thing to share with you. Enjoy!

What about keying? It looks like it might be easily possible to insert the (yes, very cute!) cartridge backwards...

2018-12-05 23:35:27 +0000 UTCive got a bag of these on the bench so its crazy you are doing this too. Ive noticed there are a few different times available is this based on bitrate? we should look at all the user adjustable options, also, electret mic, is there a way to use a line level signal to clean up the sample?

2018-11-17 18:16:49 +0000 UTCThe two unpopulated pads on the board itself seem to be for an optional Rosc. It is spec'd to 80k to 200k for 8kHz to 3.2kHz sampling rate. I wonder what would happen if you would change the resistance while recording or playback. <a href="http://www.inkocean.in/lx20lya-10-seconds-to-20-seconds-of-recording-equipment-megaphone-chip-ic-12-feet-isd1820cob-l2f2" rel="nofollow noopener" target="_blank">http://www.inkocean.in/lx20lya-10-seconds-to-20-seconds-of-recording-equipment-megaphone-chip-ic-12-feet-isd1820cob-l2f2</a>

2018-11-17 09:23:21 +0000 UTCHi Fran, nice work! Please consider giving these card cases or the connector some sort of key so they cannot be inserted in reverse. I reckon that would cause destruction of at least the module. How about a 13th "blind" pin in between, like IDE cables had back in the day?
