Introduction

Here I gathered togetyer some information, which was vital to me, yet hard to find on the Web. Generally here are tables and math formulas, sometimes methods of solution and technological hints. This place will still grow.

TABLE: wire diameters versus gauge numbers

Because on the web there are many designs made by people from US, where traditional unit system is still used, I think, that this table will be siutable for all the normal people using SI system:

TABLE: Pinout fo Hewlett Packard (HP) / Compaq Multibay socket adaptor

This is pinout for laptop / notebok Multibay connector. Quite rare bit, if You ask me -- it took whole night on google to find it and then some more to decipher and put together. Some versions of the socket-plug are NOT KEYED, so one has to recognize upper and lower rail by finding GND pins (using eg. ohmmeter). On HP/Compaq NW8000 there is enough space inside multibay floppy module to install there headphone socket. When this is connected to CD audio pins, it will act as audio Line-In, without need to insert whole notebook into docking station.

TABLE: Data for Russian/Soviet ferrite materials & corelation table

The Internet is full of quite interesting projects of radio/electronics gear comming from Russian and soviet magazines or original design, but (putting asside the language barrier) everywhere they're using ferrite, they refer to their own system of material grading. Here below please find quick reference table, which roughly matches old soviet system with western counterparts.
Second table is a key for decoding ferrite properities from its name. Generally the letters denote purpose and chemistry of material, the number is rounded value of magnetic relative permability.
