    Can anyone out there recommend a set or parts someone who is getting into
    circuit design should get? I was thinking if I can find a kit I would buy a
    breadboard from radio shack , some small wires, and a power supply but I was
    hoping there was many a starter kit that came with a bunch of
    capacitors,resistors,transistors,etc.. and a board and power supply. thanks

    A breadboard is a good idea, but electronics is such a huge field that
    you can't have a general purpose kit. You'll need a PSU, preferably with
    3-6V and plus/minus 5 to 20V or so. A reel of rigid wire and wire
    strippers. Miniature cutters. Then a selection of whatever field you
    want to design for, say a few opamps that you can afford to destroy. Buy
    little components as you need them, unless you are a long way from the
    shop, in which case get in a set of E12 values of resistors and a range
    of capacitors. If you want to do microcontrollers, think about
    programming- the easiest ones are those with serial download, say the
    Philips 89C51RD2. They have no trouble running on a braedboard too, but
    you'll need a crystal or two (easiest if it's 11.0952MHz for Baud rate).

    Could go on a long time, but it all depends on what you want to do...

    I remember when 'science kits' were sold that you could build several
    projects with. The parts and a kind of protoboard were included along
    with complete instructions.

    If such things are not to be found today, get a 'protoboard' from Radio
    Shack. It lets you plug parts together without soldering or messing up
    the parts.

    From there, find some simple circuits from magazines or the internet,
    and find a local parts store that sells to the local repair shops (most
    towns have one somewhere) to get the necessary parts.

    You may want to run your first attempts on batteries - its much safer.

    Anyway, thats what I did when I was 10. I just have never quite doing
    it 40 years later. (see website below)

    I think it's best to make up your own "kit", so you'll have what you
    need to build the circuits that are of interest to you...

    First, I'd recommend getting a book with some simple schematics for
    experimental circuits. Radio Shack used to have some, and I'd bet they
    still do. Forrest Mims has some good books that Rat Shack carried, if
    not, look for them at http://www.amazon.com. Some simple 555 timer
    circuits are quick to build, and they can do some interesting things.
    Next, get a breadboard (http://www.jameco.com has some large one's at a
    good price), some precut breadboard wire (or buy some thin, solid (i.e.
    not stranded) wire and wire cutters/strippers and make your own), and
    whatever components you need for your circuit(s) of choice.

    If you get one or two books with some simple circuit schematics, you'll
    find that several different circuits can be built with just a few types
    of ICs (555 timer, common op-amps, etc.). Then you can go to your local
    Rat Shack and buy a few of these multipurpose ICs, an assortment pack of
    resistors, a few different cap values (or maybe even an assortment pack
    of caps), some LEDs, etc. and you'll have your own beginner's kit!

    Oh, and I'd definitely go with a battery holder and some batts for your
    supply initially.

    Regards,

    Paul

    E12 is the '5%' series, but these days you get 1% tolerance resistors in
    this series:

    1, 1.2, 1.5, 1.8, 2.2, 2.7, 3.3, 3.9, 4.7, 5.6, 6.8, 8.2, 10

    ... and so on for each decade, at least 1 ohm to 10 Mohm.

    It's called 'E12', because it's loosely based on a ratio of the 12th
    root of 10 between adjacent values.

    You can also get some types of capacitors in the same range of values.
     
  7. Ok, I thought that was perhaps what you were referring to but have never seen
    it referred to that way. Only I'd put those numbers above in the "10%
    series", the 5% series including other values in between them, like 1.1,
    1.3, 1.6, 2.0, 2.4, 3.0, 3.6, 4.3, 5.1, 6.2, 7.5, and 9.1. Years ago when I
    first started working with this stuff you never ran into those, these days
    they seem to be relatively a lot more common.
    Yes, much more so than what was out there way back when.

    Do you know if there's a set of "standard values" of a similar nature for 1%
    parts? Precision resistors, in particular. I wouldn't mind having a list of
    those numbers, if there's one online somewhere.
     
  8. For the 1% parts, it is E96
    1.02 1.05 1.07 1.1...
    Have a look at:
    http://www.omegaco.demon.co.uk/mectnpdf/mectn201.pdf
    For a full description of the values.

    Best Wishes

    I suggest you get a 15 watt soldering iron, solder, one of those
    little holders with allagator clips, and order a couple of simple
    (but interesting) kits to build to get a start. Once you get the
    kits working, you should have some soldering experience. Some of
    the simple kits can be modified to make some more interesting
    gizmos. Below are two simple kits that can be tweeked for
    computer/web control, the LED chaser becomming a webcam video
    switcher by following the bottom link..

    You are right; the 5% series is 'E24'.
    The series is called 'E96'. I don't know where you can find it on line
    but *everything* is said to be on line somewhere!

    What do you want to design? Do you know? What is your skill level with
    tronics? Age might also be relevant, depends. As ever we need the
    relevant info to answer the q properly.
