Looking for information on the Blue Cube

We are gearing up to install another part of Sunnyvale’s important history: the world-known but still secret Blue Cube. Now that many of the programs coming from the Blue Cube are declassified, we would like to gather as much information about them as we can and install a permanent exhibit in the museum exhibit hall dedicated to it. If you or someone you know ever worked there, and can now talk about your work, please email the museum and join a committee to help design the exhibit. We need your help in deciding what is important. We are also interested in obtaining any related artifacts you may have from those projects.  Please email info@heritageparkmuseum.org or leave a comment on this post.

Donations – Audio oscillator

At the Heritage Park Museum we are grateful for all of the donations we have received over the years. One such donation is this audio oscillator. The 200A model was the first product by Hewlett Packard and was manufactured in David Packard’s garage in Palo Alto in 1939.

An audio oscillator is an instrument that generates one pure tone or frequency at a time. Through the years, HP oscillators were used to design, produce and maintain telephones, stereos, radios and other audio equipment.

The 200A was the first commercial oscillator to use a simple light bulb as the temperature-dependent resistor in its feedback network.

Walt Disney bought eight of these oscillators for use in the production of Fantasia. (source: Wikipedia)
