elect Posted December 11, 2004 Report Share Posted December 11, 2004 What is a max memory storage of this IC? Quote Link to comment Share on other sites More sharing options...
Dazza Posted December 11, 2004 Report Share Posted December 11, 2004 If you are referring to the schematics I posted, sorry I'm not sure, I think it's 20 seconds. It may also be obsolete, but there are many others that you can use for different record Times. I have come across one that will record up to 60 seconds, rather expensive though. I haven't yet put one of these devices together, I haven't really looked into it. Quote Link to comment Share on other sites More sharing options...
thisistausif Posted December 11, 2004 Author Report Share Posted December 11, 2004 hello is there is any ckt with which i can record only one time as if i use it in toy only to play voice no need to RErecord voice. Quote Link to comment Share on other sites More sharing options...
CRE Posted December 12, 2004 Report Share Posted December 12, 2004 The ISD's use non-volatile memory (EEPROM) so all that you would need to do as far as I can tell is connect a mic and record button long enough to record the desired sound.... then remove the two and insulate the record pin to prevent it from grounding.I'm just a newbie with alot of this so if someone with more exxperience would care to verify this I'd appreciate it.

trigger Posted December 13, 2004 Report Share Posted December 13, 2004 More to play with ISD IC, you can set the address pin and record say for example, 2 messages with 5seconds time; and also can play them back also.I have done this in a keychain recorder which serve very well. 8)Later I will give out a schematic how to do it and also some pictures of my designed product.(next week I will post..... got a lot to work on with my examiniation......... ) Quote Link to comment Share on other sites More sharing options...
thisistausif Posted December 13, 2004 Author Report Share Posted December 13, 2004 hellois it a better option to design a cob ic for this purpose, if yes then howsuppose the voice to be played in my own as "i am lion"so a cob ic giving output as above Quote Link to comment Share on other sites More sharing options...
Guest Yevgenip Posted December 14, 2004 Report Share Posted December 14, 2004 How about a micro tape recorder, but instead of tape, put in a small closed loop string that is just the exact length of the tape path. You can also use this to train talking perrots ;D (or parrots, don't know how to spell it :-[). Quote Link to comment Share on other sites More sharing options...
CRE Posted December 14, 2004 Report Share Posted December 14, 2004 Well, the tape option would work, but wouldn't that require a LOT more in the way of components, space and overall power?A COB might not be a bad idea but I couldn't begin to tell you where to go to get that designed, much less produced cheaply... Unless you're planning a full production run, in which case I'd still probably prototype the first couple using ISD chips, then go with COB when you can afford to hire out for it.... as far as I know it's nothing most people (even hobbyists) could design much less make from home.
