This blog serves as an information repository for myself, and the information is posted for consumption by the circuit bending community at large. Feel free to use any information gleaned herein for your own bending purposes.

Warning: I make no guarantees of my methods as I know next to nothing about electronics. I will however guarantee that you will end up destroying a toy or two in your circuit bending endeavors and if you do so, it is your own fault.

You can send your questions, tips, news, ideas, et. al. to octatone@gmail.com.

Octatone's Bends: Vtech Talking Whiz Kid Plus Documented



The Vtech Talking Whiz Kid Plus is a fairly stable benders playground. there are more than a dozen bends that will yield similar results of the toy crashing and spewing out random bits and pieces of words. The tough part is finding bends that do not sound too much the same.

From the top of the piece, you can see I paid a paltry $1.99. The toggles trigger bends from left to right as follows: random spew A, rhythmic loop slow, rhythmic loop medium, rhythmic loop fast, "tremolo" warble slow, "tremolo" warble fast, sample freeze, random spew B.



From inside, you can see the cavernous amount of unused space where the main board resides. There is more than enough room for 20 or more toggle switches if one so dared.





To get to the main board you must detach the keyboard by either unscrewing the connection between to the main logic board and keyboard, or breaking off the excess plastic holding the keyboard in place (the three red dots in the lower area of the above photo).



Now for the bend points:

Random spew A: brown with white stripe to red with white stripe
Rhythmic loop slow: pink to light green with white stripe
Rhythmic loop medium: red to light green with white stripe
Rhythmic loop fast: green to light green with white stripe
"Tremolo" warble slow: pink to gray with black stripe
"Tremolo" warble fast: yellow to red
Sample freeze: yellow to pink with black sripe
Random spew B: blue with white stripe to red with white stripe

Octatone's Bends: Vtech First Words Toy

Front
I bought this the same day I grabbed the 99 cent geetar. This past Wednesday I finally bent it. I found pitch up and pitch down bend points as well as a jump that only works when the pitch up/down bends are active. The final result is a fairly simple noise making toy. For playability I added jumps to the pitch up/down bends to max them out instantly.

Inside
Inside you can see the signal flow of the bends. The pot I used has a built in switch which is handy. I placed the down bend pot and the body contacts next to each other because they work best together - the body contacts don't work as consistently with the pitch up bend. Placing the up bend toggle and photocell above the down bend makes it easy for me to remember what they do. The pushbuttons short the pitch bend signal path for instant max high/low. There is a 250k resistor on the signal from the speaker to the 1/4 out tip to tame the way too hot signal for use in a mixer/amp.
