Updated 90s recordable greeting card = "Say & Send Friends "

Had a tight budget Digital Voice Recording (DVR)educational project in
mind, & recalled those 10 second Hallmark recordable greeting
cards,once popular in the early 90s. My 2005 idea involved
modification to suit a Picaxe microcontroller, delivering user
generated sounds rather than boring old speech synthesis. It's been
done with a Basic Stamp & makes a most attention getting device! Sadly
the Hallmark cards have long gone,as has also a later 90s "Yak-Bak"
gizmo that repeated back ones voice or songs etc.Kids stuff!

Recordable postcards & photo albums ARE still around, but at the $$
level...

OK -they may have been novelties even at that time,but their quality
electronics were worth more than the final toy! You know how it goes -
take the guts from a solar powered garden lamp worth a few $US &
create a $$$ electronic design...

The solid state (zero power EEPROM stored-good for 10+ years)
electronics in these early DVRs gave suprisingly good speech
quality,with circuitry usually based around (Winbond) Information
Storage Devices (ISD)"ChipCorder" range. These chips alone retailed
~US$5-$10,typically as their ISD1110 or ISD1020. Fast forward to
2005,& their ISD1420 (=20 secs)& ISD2560 (60 secs)look the equivalent,
with tradeoffs between recording time & bandwidth (= voice quality)now
possible too. See a complete list =>

OK- toy shop time. Guess I should have asked a 3 year old earlier on
for my electronic market research, since -BINGO- a charming talkative
Teddy Bear. These cuddly Wild Republic "Say & Send Friends" bears were
apparently all the rage just last Xmas(2004), & presently sell ~US$10.
The sound module is velco pouched within the bear, & gives a great
quality 10 second greeting when it's tummy is pushed. Maybe have some
recording fun with older kids(& yeah-teens!),then slide out the neat
recorder for workshop enhancement & give the bear to a younger child?

Well that's the plan, but my nursing wife has promptly run off with
the bear to amuse her patients. Further postings when Teddy reappears!

I've now opened the S&S sound box, & find the SMD chip buried under
the usual black blob. Grr. It may not be a zero power ISD Flash type
since a tiny sleeping current (~1.5 microAmp) noted & stored messages
are lost after some minutes when the batteries are removed. See pix =>

Adaption for (at least simple) Picaxe micro use & larger
batteries/switches looks easy however - especially at the all up
bargain price! This could make a nifty school project (hint hint), or
maybe a UHF CB range extending simplex repeater to suit emergency,
search & rescue use etc. Stan
 
Voice recorder chip update - my spies further inform that Taiwanese
firm Honistak Electronics have just released 2 new 28 pin DVR chips,
HK828/827,already stocked by Jaycar Australia as ZZ8200 (~Aust$20).
