One of the more difficult aspects of getting into building
circuits is parts sourcing: the process of finding the right parts
locally or online to build your project. For seasoned hacker pros,
this process is not terribly difficult, but for everyone else,
getting the right part can be difficult. Not because they aren't
available, but because there are so many variations and varieties it
can be hard to actually order the correct part. One of the key
features of the beavis box is the Parts Stash: a well-thought-out
collection of the most important parts you'll need to build great
stuff.
Oh, sweet semiconductors! Here's a list of what's in the standard parts stash (if you
don't know what these are, don't worry: they're all explained in the
Hacker's Guide to the Beavis Board)
- Resistors: 5% tolerance 1/4 watt metal film parts. Values
from 10 ohms to 1M ohm.
- Ceramic capacitors: A bunch of
the most common values: 10pf to 470pf.
- Film capacitors: Low-voltage poly film parts. Values from
1nf to 220nf.
- Electrolytic capacitors: 16 volt parts. Values from 1uf to
220uf.
- Diodes: A great selection of diodes for clipping and other
audio uses. Values: 1N914, 1N4148, 1N34, and Zener.
- Transistors: A collection of bipolar silicon, JFET and
MOSFET parts. Types: 2N2222A, 2N3904, 2N3906, 2N4401, 2N5088,
BC109, MPSA18, 2N5457, 2N45458, 2N7000, BS170, J201, and MPF102
- Integrated Circuits: some of the more common (and some fun
obscure parts too). Types: 741, JRC4558, LM386N3, LM567,
LM833, NE5532, RC4558P, TL071, TL072, TS555CN, CD4049UBE, LM556,
40106, and JRC386
- Potentiometers: Alpha 16mm pots. Values: B1K, B10K, B50K,
B100K, B500K, B1M, A25K, A100K, and A250K.
- Breadboard jumper wires: a standard collection of colored
solid-core jumper wires.
- Some other fun stuff thrown in for you to experiment with.
Note: the exact make-up of the parts stash changes
over time as I find interesting new parts and things that make
good tonal differences for the projects. |
