Help Cards

Over the years I’ve either created or found small crib sheets or help cards that are useful to keep around the workshop for when the old grey matter lets me down. I’ve got a set of these all laminated (was a great reason to buy a laminator) and they are super useful.

Anyway I’ve combined all the useful information from all these odd cards and scraps of paper into one PDF file. The printed output is A5 in size so handy to keep around the bench.

The V3 card contains information on 74 Series ICs, resistors, capacitors, ohms law, cable sizes and current carrying capabilities, frequency and electronics units conversion, an ASCII code table and a table of useful information for driving 7-segment LED displays.
