The kit includes a high quality blank PCB, all ICs and LEDs, other electronic parts, detailed assembly and test instructions, and operation manual. A low power or temperature-controlled soldering iron, rosen core electronic solder, and a fair degree of soldering skill will be needed to assemble the kit. There's a LOT of soldering and the pins are tightly packed. If the smallest thing you've soldered was watering can using a 5 pound iron heated in a furnace, STAY AWAY from this kit! You will ruin it and I will not even attempt to repair a PCB that has been obviously damaged by poor soldering technique!!! However, if you're good at electronic soldering, it should only take a couple hours to assemble.

Using this module will require a working laser head/transducer. However, the output power can be way below HP/Agilent specifications and below the level where the internal receiver is active. Even 50 uW should be much more than enough output power. (However, for 5517/18/19 lasers, an external reference optical receiver may be needed below about 100 uW.) In addition, interferometer optics with retroreflector or plane mirror, and an optical receiver will be needed. These can be standard HP/Agilent parts, or home-built opto-electronic components. A regulated 5 VDC power supply, 1 amp minimum, is needed for the module. Some of the HP/Agilent power supplies may have adequate 5 V capacity but I do not know which ones.

One prototype SG-MD1 has been assembled and-MD1 is presently in final test. I have another blank PCB for my own use. To proceed with the production version, I would like to have several confirmed orders with deposits in-hand.

See Installation and Operation Manual for Sam's Interferometer Measurement Display System 1 (SGMD1) for more info including complete specifications.
