Quick rundown now I've got a few minutes. Most of it appears to be brand whoring and is *very* expensive.
page 1105Any old push button/toggle switches will do. Solder some 1/0.6 wire to them and whack them straight in the breadboard.
TO-92 heatsink. Epoxy a small copper coin to the plastic case.
Transfomer: use a 6v/9v AC wall wart. Does the job, won't kill you.
page 1106Trimmers: buy some cheap chinese bourns 3386 clone blue cermet finger trimmers as they don't knacker your breadboard. These ones:
Diodes: anything will do here really apart from the schottky. Sub 1n914 for 1n4148 for example. BZX series for 1N5232 if you're this side of the pond.
page 1107Transistors: MJE2955/3055 - these are TO220 packaged 2n2955/3055 which are usually cheap as chips. Solder wires on them or they will kill your breadboard, same with TO220's! 2n3904/3906 can be subbed for bc327/337.
MOSFETs: these are fussy buggers so best to stick with the recommendations.
JFET current source: 1N5294 - these are impossible to get hold of in Europe: just use a JFET (J310) and a series resistor - same thing.
page 1108Switching regulators: LT1073's are damn expensive. Learn about the On Semi MC34063A- dirt cheap and just as capable. Read the data sheet and application note for it. Anything Linear Technology (LT) is a mugging.
page 1109Logic: all sensible ish. 74LS503 - WHYYYYYY it's dead.
...gap here as I haven't read the digital section further...1111Capacitors - ceramic: forget AVX CK05 - damn expensive. Grab some cheap blue MLCC's for 1n+ and use simple single layer ceramics discs for lower values, get NP0 ones if you can. Murata = win - quality and cheap.
Polyester: get polybox ones - dead cheap. Who cares where they are made. The cheapest no brand ones I've bought are as good as the top line AVX/Vishay ones.
Tantalum: don't buy these - they are damn dangerous to learn with. They blow up in your face if you look at them funny. Use cheap but branded electrolytic units i.e. Rubycon, Panasonic etc. They're good enough for this course.
1112Resistors: grab a big bag of 5% 1/4W carbon film ones. Don't bother with the Allen Bradley or SEI branding. Probably about $5 from China.
Equipment50MHz analogue scope. Tek 465 series fits the bill nicely. That's what I use anyway.
2MHz function generator, preferably with sweep. If you can't find one with sweep, w2aew has a video with notes here on how to build a suitable ramp/sweep generator. You can literally just whack this into the VCO/sweep input on a normal function generator and trigger your scope off the 555 output pin to do frequency sweeps for filters etc:
I just built the front end of this and tested it with my prototype FG and it works nicely although I only had TL072's around - still works fine.
Some other things not mentioned:
Buy lots of Pomona minigrabber to 4mm leads. At least 4. These things make life a million times easier instead of using meter probes etc as they stay put. Use a Pomona BNC socket to minigrabber on the end on an RG58 patch to inject your signals.
