A cache and Dash with History

Thomas Edison held a record 1,093 patents for his inventions, this series visits a few of the less known inventions he made.

Replaced the container in a slightly different location in the 3 foot area. Also changed the difficulty and terrain to accurately reflect the cache.
Thomas Edison

The first great invention developed by Edison in Menlo Park was the tin foil phonograph.

While working to improve the efficiency of a telegraph transmitter, he noted that the tape of the machine gave off a noise resembling spoken words when played at a high speed.

This caused him to wonder if he could record a telephone message. He began experimenting with the diaphragm of a telephone receiver by attaching a needle to it.

He reasoned that the needle could prick paper tape to record a message.

His experiments led him to try a stylus on a tinfoil cylinder, which, to his great surprise, played back the short message he recorded, "Mary had a little lamb."

We checked the light post, cable box, and evergreen tree, but no cache to be found. We'll watch the logs and come back for another look if this cache is found or replaced.
