Speak&Spell Bending
uçÚº[
The “HOLD” feature in the schematic above takes some fine tuning to get right. There are parallel resistors and buffer resistors, a pot and a switch. The values of the potentiometer and resistors for this feature are meant for reference only. I’ve found that they often need to be tweaked from model to model. If you are new to bending, don’t bother with the adjustment and the trim resistors, just wire the switch to the two “hold” points on the main board. The same goes for the “LOOP” feature. The adjustment lets you fade between loop and glitch effects, but it takes some tweaking. It’s much easier to take out the pot and resistor and just wire in the switch.

[…] Pete Edwards of Casper Electronics has recently posted a ton of new material to his site including a segment recorded by a Swedish TV show SHOWROOM. The video is packed with great footage of Pete’s workshop along with an explanation of what circuit bending is and some actual Speak and Spell bending. Pete also posted an intense collection of Speak and Spell diagrams and an authentic schematic of a Speak and Spell circuit in the Speak and X circuit bending section. The Barbie Karaoke machine bending page now also features more in depth documentation. Thanks for sharing the info Pete. […]
