Semiconductor Analyzer Review

Draft, not ready for reading

This is a kit from.... link .... which promises to tell you what ( in electrical terms, not part number ) that unknown transistor is.

Order process

Went smoothly, kit arrived quickly. Nicely packaged. Either they forgot the assembly directions or I lost them, an email resulted in the directions arriving within a few hours, on a weekend.

The Kit

All of the parts looked first quality, pretty much industry standard parts. The board was very professional, nice solder mask and well marked. The IC were all dip parts and the routing was not agressive. Everyting needed for complete assembly ( including the enclosure which I ordered as an option ) was there. The first suggestion in assembling the kit is to verify the parts against the parts list, I eyeballed it. Later it turned out that indeed everyting was there. The parts are usefully broken down into different sets in diffent bags. Solder and tools are up to you. The microcontroller ( I presume ) has its part number hidden. Source code is not provided, but updates are available.

Building

This is pretty straightforward, stuff an solder. I followed the directions anyway, except I added extra seckets for the 74HC4052 Dual 4-channel analog multiplexers. Then I double checked the parts. The resistor color codes are difficult to distinguish ( not their fault, this is an industry standard ) so I used a magnifier and double checked with a ohmmeter. No mistakes found.
