Mouse-sized Synchronous Hour Meter

This is a tiny aerospace hour meter, new old stock, tested and working. Diminutive hour meters like this were mounted in individual pieces of test equipment and circuit modules so the runtime of each board or plug-in unit could be tracked separately for scheduled maintenance. The meter is truly small, with a size of 12mmx12mm and a length of 29mm, you could fit dozens of these in the footprint of a traditional Haydon hour meter. This meter is rated at 115V 400HZ, and consumes 0.1 watts. This unit will run at 60hz line voltage, but it would be useless as a timer at this frequency since the line frequency is also used as the timebase for the motor.

USN 1N696 Diode

USN 1N696 diode, new old stock with minor shelf wear. This small diode is encapsulated in a gold metal can package with flying leads bonded to each end. Unfortunately we do not know the specifications of this device, but it likely dates from the 1960's given it's part number and construction style.

Osram 2010 LED Display

Osram 4 digit red ceramic LED display, used condition, tested and working. These are rugged ceramic hermetic displays for use in medical and military settings. The displays have internal shift registers and drivers, as well as individual wire-bonded dies for each pixel of each digit. The displays have clean leads and there are no chips or flaws in the glass that I can see. Datasheets are readily available on the Internet, the datasheet for the HDSP 2010 will work with this part.

Raytheon CK502AX Peanut Tube Module

Peanut tube plug-in device, unknown function, used condition. This unidentified device contains three Raytheon CK502AX peanut tubes as well as a number of passive components, all of which has been mounted to an 11 pin phenolic base. Unfortunately we have no idea what these modules were intended for, though they would likely be useful for someone who needs to salvage CK502AX tubes for another project.

Chicago Miniature CM20-2 Lamp

Chicago Miniature CM20-2 incandescent lamp, new old stock, tested and working. These unusual bulbs were intended for use as optical sensing units in early time lapse VCRs, and have a curved glass lens incorporated into their envelope. The lens exits the bulb at a 90 degree angle to the filament, which makes them ideal as colon indicators for clocks based around large numitron tubes like the DR2000 and IV-13.

OD-2086 UV LED

A mysterious OD-2086 UV LED, like new condition, tested. In outward appearance these appear to be a metal can UV LED in the vein of the well known Nichia NSHU550 first generation UV LED, but in a gold enclosure with a flat glass lid. The internal construction appears more primitive as well; there is no reflector cup for the UV LED die, and the raised internal platform found in the NSHU550 is missing.

Note: these LEDs output a shorter wavelength of UV than commonly available 5mm epoxy LEDs, and as such they should NOT BE VIEWED WITH THE NAKED EYE! Looking at these LEDs while powered can cause permanent vision damage.

Three Electrode Glass Bulb

Three electrode glass bulbs, gas filled, clean condition. When brought near the influence of a Tesla coil the bulbs fill with a purple discharge, and when a high voltage supply is connected across the leads purple bands form as shown in the photo. These could be some sort of high voltage arrester, or a three electrode trigger tube. The bulbs look to be in good shape with no silvering or other fouling of the glass.
