I just received an SP0256-017 purchased on Ebay as the one on this picture from Flickr. This version of the SP0256 was designed for talking clocks. I work with the help of a dedicated EPROM which hold the code for the numbers (without the EPROM,…
Having a working Votrax SC-01A hooked to an Arduino, I wanted to test the inflection bits to hear their influences on the speech. Inflection To get the inflection working we need to toggle the to inflection bits low or ligh. The Votrax’s inflection entries are…
Took me quite a while to finalize my midi in interface ! A lot of time wasted because I used a MCT2 optocoupler with the “standard” 200 ohms resistor on the incoming signal. The output form the optocoupler to the arduino was quit weak (thanks…
I always wanted to have some fun with the SP0256’s pitch. I started to change the crystal with some I had lying around. (2.4576 MHz, 3.2768 MHz, 4.0000 MHz) The SP0256 worked just fine at these frequencies (Follow the links to hear some samples) Eric Archer…
After some fun with the SP0256 (more to come on this) I decided to try the Votrax SC-01. (I found it on Ebay). I followed this schematic: http://kevtris.org/Projects/votraxtnt/index.html I also found a lot of resources here: http://www.redcedar.com/sc01.htm I made this schematic And coded the Arduino…
Back to vintage ’80 robotic sounds I had a SPO256-AL2 on a 1989 circuit designed to act as a vocal printer. I decided to hook it to my Arduino Mega. With the help of various ressources I got it working whithin an afternoon
