I have just completed designing a steampunk "Adventurer's Helmet". Hopefully this will soon become available for purchase. It will be made overseas. It is made primarily of brass and leather.
It has a double row of aether collectors on the crest that feed energy to the storage batteries around the back, which run the Alien Life Form detector in the front. It also has an auditory amplifier brass horn that feeds sounds to the left ear. Let me know what you think.
