eBay seller Turbo_Mac has a few new gadgets up for sale. One of them, strictly speaking, isn't a clock at all but it is an EM84 "magic eye" tube that he has re purposed as a a VU meter. The device has both an internal microphone and as line-in (not in a mini plug connector, however) to control the display. Bidding starts at $1 and ends in 7 days.
This is a fully assembled 6E2 (EM84 equivalent) VU meter that accepts both line-in and on-board mic signal. Its glowing bars close while audio input is strong, and open while it is weak. They're like naughty jumping elves! The continues patterns provide ultra fast response than any other VU meter! Please refer to the video below or contact me for other details.
