Hello fish,
Hello all,
yes it has a 2032 coin cell because other nonvolatile Ram IC 's like MRAM or FRAM need
a voltage translation for all adress- and datalines from 3,xV to the Prophet VS 5V (and vice versa)
and so on.
This makes the circuit difficult and a lot different converter IC 's are needed.
I have done this in a breadboard construction but i decided to go the easier way.
The Ram 's from today have such a low current usage in standby.
That should result in a durability of the coin cell for manny manny years.
i will preload the first Bank1 of the 16 Banks with sounds and the other 15 Banks will be
pre-formatted for the user to load his favorite 15 Soundbanks on it.
If someone ist interested send me a mail to maxinzinger(at)yahoo(dot)de
I have now 5 pcs. left for sale from my first small pcb purchase order.
If there are more people interested i have to order new "Hardware" and parts first.
Find time to assemble all and 3D-print the enclosures comes on top.
More than 10h per enclosure !
Best
Mikke
