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.

Soviet Hermetic Green LED

Unidentified Soviet hermetic green LED, new old stock, clean condition. This early device contains a green LED die mounted to a thick gold header with a glass window and metal lid. We do not know the part number or specifications of this device, but its light output is quite dim, and only useful as an indicator.

Luxeon LXS8-PW30 LED

Phillips Lumileds Luxeon S1000 series LED, new old stock, bulk packed from trays. This is a powerful device for a compact cavity LED, and has an output of 1390 lumens at 25 volts. The cavity contains nine LED dies wired in series, which are mounted to a complex wafer with gold traces. This LED also produces decent color rendering, with a CRI of 80 and a color temperature of 3000k, the light has a faint yellowish tint that is pleasing to the eye.

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.

Weird RGB Discrete Die LED Display Bar

An unusual RGB LED light bar display, working and tested. This display has visible discrete dies ball-bonded to a gold clad PCB, with dies in three colors; red, green and blue. Each die is individually controllable through the 30 pin FFC connector on one side of the device. The LEDs are protected by a clear epoxy coating to prevent damage. This is a very rare display and I have never seen anything like it before, what unusual projects could be built with such a device? RGB point-of-view display? VR headset variable color tempature backlight? VU meter designed by a madman? Comes with ribbon cable.

NEC D7220 Integrated Circuit

NEC D7220 video controller IC, new old stock, still in original tube. The D7220 is a highly regarded video interface controller that was popular in the early 1980s. This chip can draw circles and lines to a bitmapped CRT, and also includes support for light pens and complex character graphics. The D7220 saw use in a number of early computer systems from NEC and Digital Equipment Corporation, including the DEC Rainbow and the NEC APCIII.

SCS 1007CRT

SCS 1007CRT integrated circuit, clean socket pull. The SCS 1007 is an integrated alphanumeric minitron driver IC designed for use with displays like the Wamco KW-105AL. The chip is packaged in an early gray trace ceramic carrier with a gold cavity lid. There is no date code on this chip, but we suspect it was made sometime around 1970.

Wamco KW105AL Minitron Display

Hard to find Wamco KW105AL alphanumeric 'Minitron'-style incandescant display, in tested and working condition. Commonly, used in military equipment, the KW105AL uses an array of heated lightbulb filaments to display numbers and letters, which have been shoehorned into a tiny rectangular DIP-style envelope. The KW105AL is rated for 100,000 hours at 5VDC, and will probably last much longer at lower voltages. Digit height is .300 inches and the display is .468 inches high. All segments test good; these are practically impossible to find, and would be a good addition to a tube or display collection or for construction of a "four letter word" clock or other display project.

Soviet ALS317B Bargraph LED

Soviet ALS317B red bargraph LED, new old stock, clean condition. This tiny display contains 5 bar shaped LED dies and can be stacked end-to-end to create bargraphs of any length. Though this device is packaged in what appears to be a six pin DIP package it should be noted that the dimensions are much smaller than a standard DIP... the epoxy package is 5mm by 5mm and the leads are 7mm long.

Micro Burroughs Panaplex II Neon Display

A tiny Burroughs Panaplex II branded neon filled display, used but tested condition. This is a neon filled seven segment display with 4 and 1/2 digits and colon in a tiny flat glass envelope, it is uncommon to see a Panaplex display that crams this many digits into such a small space. This display has full length leads and is not desoldered,and all of the segments test good. The display has a label on the back indicating it has been doped with krypton-85. Maybe it is time for someone to build a Panaplex watch?

Luminus XNova CXM-22-27-80-36 125 Watt LED

Luminus XNova CXM-22-27-80-36 high power LED, clean unused condition, tested and working. These are insanely bright 125 watt LEDs, and can produce an eyeball-watering 7800 lumens of light output. Color temperature is rated at 2700K; these produce a warm white light similar in color to the output of an old-style incandescent bulb. They are obviously much brighter than an incandescent bulb however... a typical 100 watt incandescent bulb can only produce about 1500 lumens of light. Needless to say, these require a heatsink when operated at full power, and will quickly immolate themselves if ran bare. If you ever wanted to construct a flashlight so powerful that it could be seen from space, this might be the LED for you!
