    Default DIY Pendulum Harmonograph instruction

    Greg, and any others interested, in case you didn't see this PDF I posted in another PLF post. I made one back in 1977 and was impressed with its capabilities.

    Default Another Harmonograph...

    The Exploratorium has long had a large harmonograph on the museum floor. I have included the construction details below for any interested parties. It's very popular with the public!
