Hi remedios667,You can definitely build the circuit with 555's instead of 556's. you would need 4 555 chips to make the Haunted House Bones sounds.I can't put together a schematic for you, but you can easily correlate from the 556 to 555. Please share your results when you make it!
I learned everything I know about 555 timers from Forrest Mims III. His book, 'Timer, Op Amp & Optoelectronics Circuits & Projects' is where I got the building blocks for this project.If you are in need of a constant sounds, then you should not use the one-shot circuit. I'm using the oscillating parts of the timers to effect the oscillator output. at the end, not the outputs of the actual timers.
