We have added a few new items to the Electronics Museum, including an unusual device, the Soviet IV-29 dot indicator. Never before has the humble lamp been lavished with such over-engineering; the IV-29 is an entire hot cathode VFD tube built to display a single round dot. Large numbers of IV-29s would be soldered into matrices and segments, allowing characters and numbers to be displayed in pixel-assembled form.
We have added several items from Hamvention to the site as well, including an EMI 9826B photomultiplier to the Detection Tubes section and a Central Electric CVS-1 high vacuum switch to the Spark, Trigger, and Passive Tubes section. Our somewhat anemic Aerospace Components section has also received a new item, a Northrop 09641001 voice recorder magazine. This reel-to-reel recorder takes the tape deck to new heights of military over-engineering.
