Hardware with something to say
Shipments and returns Your pack shipment Packages are generally dispatched within 2 days after receipt of payment and are shipped via UPS with tracking and drop-off without signature. If you prefer delivery by UPS Extra with required signature, an additional cost will be applied, so…
The idea Mozzi by Tim Barras is an outstanding library that allow the Arduino to produce complex and exiting sounds with almost no additional hardware. (In fact MozMo uses the hifi mode that requires … 2 resistors and a cap !) The idea was to…
Schematic Here is the schematic. Nothing really special : A simple RC filter I have used before with the Talkie library and a few pots to fiddle with the various functions. All the entries (cv and gate) are now protected with diodes to allow connections…
Credits This arduino based module works thanks to a clever library : Talkie from https://github.com/going-digital/Talkie I have already used this library to build a Talking clock It is so simple to use that building a sound module requires only 5 pots and a button to…
The almighty SSI-263 speech synthesizer chip As you can read on the Wikipedia page, the SSI-263 is the other name for the Votrax SC-02. It is becoming quite difficult to find, much harder then it’s little brother the Votrax SC-01 but I finally got one by…
I always loved to play with sound making chip back in the ’80 (I made a synthesizer with the SN76477 in `79 which is sill working) Today it is still possible to buy some SN76489 on ebay and a few website are decribing how to…
Talkie I’ve discovered this great library here https://github.com/going-digital/Talkie They have done an impressive job. The library is provided with a large vocabulary. It is a software implementation of the Texas Instruments speech synthesis architecture (Linear Predictive Coding). It is just amazing to discover what the…
The idea I got this brilliant idea by John Loadsman who is using a version of my previous code: http://www.youtube.com/watch?v=tUbTZU_FCz0&feature=context-cha I also wanted to digitally control the Votrax’s pitch to implement some new functions. (keep in mind that I want the Votrax to sing) The hardware modification…
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…
