A young friend is getting into electronics, he's done Arduino things but he's interested in learning analogue electronics because he plays guitar.
I've already suggested some bubblegum transistors (complimentary pairs like BC547, BC557, BD139, BD140), some OPAmps (bubblegum stuff again, the TL07x ones, some 741) a few voltage regulators and diodes and some amplifier chips (TDA2030, TDA2822) but, resistors, capacitors?
I'm thinking he'd benefit from a resistor selection pack but there seems little point in having the *whole* range at first, so, E12 up to 100K with more stock of the commonly used values (the E3 ones)?
Capacitors, as he's interested in audio I don't think he's going to need picofarad values so, a selection of ceramics and electrolytics, 1nF, 4.7nF, 10nF, 47nF, 100nF, 470nF and 1uF, then the same range in uF up to 1000uF, say 50V?
A selection of variable pots and trimmers.
I've got a PSU for him (A Farnell TOPS) and an old Hameg analogue 'scope, he's already got a multimeter, not a great one but it'll do for now.
The rest of the workshop tools like a soldering iron, pliers, cutters etc. he's already got, he'll be ordering a breadboard and wires as well as some matrix type protoyping boards.
Suggestions and corrections?
