Best Electronics Kits For Adults? 376

An anonymous reader writes "I'm an adult looking to learn how electronics work and have some fun building projects. But all the kits I've found online are for kids 8-10 years old, and they don't really explain the principles — they just color-code where to place components on boards. Are there any kits aimed at adults? I know if anyone has got the answer, it's this community."

      The old HeathKits, like oscilliscopes and ham radios, were of value as exercises in assembly and part identification. Beyond getting a general sense of what the circuitry was about, I never learned anything about electronics from building such stuff.

        Heathkits were good for learning physically working with electronics. Soldering irons, pin identification, mechanical assembly, but didn't really teach theory.

        The 150 and 200-in-1 radio shack kits actually did a fairly good job of this. They started you out with "connect the numbered terminals, here's a picture", to later replacing the picture of the parts with a schematic. They encouraged you to experiment, and there was accompanying text for each project later on that described what was going on in the circuit so you understood what all the parts were doing.

        It didn't teach you electronics theory formally in any kind of structured way, but it was an excellent crash-course in basic electronics. It was also a very quick way to teach you how to read, use, and create schematics. There are still 200-in-1 kits available but not by Archer anymore: []

        There really are 200 different projects in that kit, ranging from very very basic, "press the switch to turn on the light" all the way up to "a divide-by-2 counter" and "build your own one way telephone". It teaches the basics of digital computing at the gate level which is interesting. Also there was a very wide variation in the projects. Something interesting for everyone. Photodetector alarms, simple games, noisemakers, just all sorts of variety to keep a kid interested.

        Once you want to really start fiddling, this is something you should have. It doesn't teach you anything in itself, but lets you play more: Heathkit ET-3100 electronic design experimenter: []

        I had one of these and it's very basic, but by this point you should have some spare parts around already, and having adjustable voltages and signals and a breadboard takes you to the next step of design. Actually I think it did come with some projects, it's been awhile. This was a kit, so you had to assemble it properly for it to work. I used to spend my free time at school planning out schematics of things I wanted to tinker with, sometimes preplanning how to lay them out on the breadboard when I got home.

      Try Ramsey Electronics. You can download their manuals and see what the kits are about. I recently built their FM30B FM radio transmitter kit to broadcast my mp3s around my house and yard. Besides getting to build something, you can also get something really useful out of the deal.

      The FM30 is digitally tuned and digitally controlled and the circuit description and how it all works is very good. Kit difficulty is good for first timers if they are careful and follow the directions.

      The final product sounds great too. I have my Linux box serving up the music and have my transmitter Y'ed into the line out with the speakers.

      The FM30B is $200, but they also have other transmitters for around $140, and $60 if you want a less complicated and less expensive setup.

      I learned electronics as an adult. Beginning electronics books found in the library is an excellent place to start. Check many library branches and suburban nearby districts. Often you can get a library card for the suburban district libraries with a central city card at no charge.

      Some other suggestions:
          >Get a cheap digital voltmeter for about $20. Invaluable.

          >Download several of the sound-card oscilloscope programs floating around on the web. Many of them have poor quality user-interfaces and documentation, but nearly all of them work on low-frequency AC signals like audio.

          > Get an inexpensive soldering iron and salvage/recycle parts from junk electronics, especially old electronics that used through-hole components. A spring-loaded plastic tube solder-sucker used to remove solder from joints on recycled/used circuit boards is quite useful. A solder-less 'breadboard' where components can be connected to make temporary test circuits is handy. Sometimes community college students in software have to take electronics classes to graduate. They have to buy component kits for labs. After finishing the class, they show their contempt for these electronics classes by selling their supplies for super-cheap or by giving them away.

          > Ask 'stupid' questions on 'beginner's' web sites. Ignore all the smart-ass 'stupid noobie' responses.

          > Post a message on the local CraigsList for free surplus hobbyist electronic components. You might meet local people who can direct you to local inexpensive parts-sources and assistance.

          > Be open to exploring microcontrollers. There's a real learning curve, but they are now very cheap and flexible. I recommend exploring the Atmel AVR family. I strongly discourage using the Microchip PIC, because they are a pain in the neck to program, and are not very cheap. The AVR chips can be programmed directly through the PC parallel port.

          > Most electronic manufacturers will give free samples of their parts if you ask them. It is standard practice in the electronics industry to get free samples to build a prototype of a new product, and then buy thousands of the chips when the product goes into production. You can use your work e-mail address to convince the electronics manufacturers that this is your plan with the samples.

          > Eagle makes a great free software package for creating schematic drawings of your circuits and, as you advance, for designing a printed circuit board. Google for more info and download site.

          > Several companies now make small numbers of small-sized professional quality circuit boards for $35-50. These 'board-houses' are invaluable for use with tiny surface-mount components and integrated circuits that the electronics industry is standardizing on.

      I hope that all this helps. I suggest focusing on a specific area that you find interesting. For several years I studied electric guitar effects pedals like fuzz/distortion, flangers, and echo/delays. The schematic circuits (and documentation on how the circuits work) for the older 1970s and 1980s effects are available on the web. Also you can get cheap knock-off clones of expensive effects on eBay for $15-$25 each. With a DIY signal generator (like a simple 555 timer), you can feed signals into these cheap effects clone boxes and use the free PC sound card oscilloscope programs to see how the circuitry is changing the signal through each stage of the effect.

      Best of luck.

      If I have less than warm feelings towards Heathkit, it's because almost 30 years ago, while working at the Lunar and Planetary Institute, my boss (a great guy, BTW) decided to save LPI some funds. Rather than buying assembled terminals to use with our new VAX, he instead bought quite a few Heathkit dumb CRT terminal kits and then paid me (per terminal) to assemble them after work hours.

      It did save LPI money, and it put some extra money in my pockets -- but as I type this, I can feel again the burns and cuts on my fingertips from hours upon hours of assembling and soldering, not to mention the general frustration at trying to make each terminal work (which I did, eventually). I can't remember how many terminals I built, but I know the VAX was intended to support 30 LPI personnel, so it was a lot.

      Mostly, it reinforced my earlier decision back in college to be a CS major, rather than a EE major. :-) ..bruce..

      Yeah I agree. I did the same when starting out and that's half the fun. A basic kit you buy will almost always contain a bread board, a power supply, some wire, and some basic elements like LEDs. All of these can be found in one trip to radio shack with little effort.

      For instance here could be a basic kit:

      - Bread board

      Most of the kits you find at Radio Shack are firmly rooted in the 60's and 70's, where the most high tech item in the kit is the venerable old 555 timer and maybe a transistor plus 50 cents worth of resisters and a couple capacitors and an LED or two. (A notable exception is their Parallax What is a Microcontroller []) kit. What makes this a kit for grown ups is the solderless breadboard which can be used to hook up virtually any component instead of just a few using snaps or wires-and-springs). So if you have to have it today, you could do a lot worse than the Parallax kit. Just enter your zip code to see which store near you has it in stock [] (call to avoid the inevitable "...Bill have you ever heard of this?"), and you'll be in business for about $80.

    You are an adult, and can buy your own parts, so have no need for kits.

    All you need to get started is this book - it is basically the de-facto standard for learning electronics.

    "Getting Started in Electronics" - Forest M Mims III []

    This book is basically the bible for newcomers to electronics. Buy it, you will not be disappointed. He starts off with the simple, progresses to the relatively complex, and explains all the principles along the way. Every project comes with a complete parts listing, and lots of diagrams and illistrations to help along the way. Also there is some great reference pages included that I STILL refer to occasionally.

    Seriously. The kits have nice big, brightly coloured bits which are physically large and easy to handle. They are also relatively hard to break. You don't really need those featues. Instead, get a good beginners book, for instance by Forest M. Mimms III, a solderless breadbroad, and then buy the components mentioned in the book. You can then start assembling them on the breadboard.

    For what it's worth, I'd duggest the following:

    Several reels of 100 metal film resistors, 100OHm, 1K, 10K, 100K and 1M.

    A bag of brestripped, tinned and finished wires of various lengths for breadboard prototyping.

    A reel of single core wire (for when the premade ones won't quite stretch).

    Several bags of capacitors (100p 1n 10n 100n ceramic, polyester, mica or mylar and 1u 100u and 1000u in electrolytic). You want maybe 20 of the smaller ones and 10 of the larger ones.

    A nice big bag of cheap transistors. These are a little trickier, but all of the low priced ones will be similar. You probably want something like 20 small ones like BC108 (NPN, low power) a corresponding PNP one and 5 medium power ones like BFY51.

    10 cheap LEDs

    1 Buzzer

    1 loudspeaker

    A good powersupply. You won't need more than 1Amp, but you probably want 0--15V variable, and 2 outputs if you can manage it. This is the mist expensive part, but you could just get a 9V wall wart if this is a problem. Batteries get annoying quite fast.

    This will set you up way better than a kit.

    You can also add to it later. You can buy a rail of 741 op amps (indestructible, and still popular even though they're 20 years obsoloete) and 555 oscillator chips. Later still you can get some logic ICs.

    • Please, slashdotters weigh in, because I've missed something here.
      You've got most of the key things (I'd go for more of the intermediate resistors and capacitors too, but that' personal taste). Add a multimeter to that selection, and you've got a reasonable mix. Better would be an oscilloscope, but that's a much bigger outlay. Also, it's probably a good idea to get some cheap switches (both toggle and push-to-make) and a few variable resistors. And if you're going to experiment with building a radio, definitely get a variable capacitor and a diode. (If not, don't bother.)

        If you aren't working with high frequencies, second-hand analogue oscilloscopes are cheap. I got a 20MHz, 8-input Tektronix rackmount oscilloscope for about $40 on eBay. Since I'm mostly interested in working with audio frequencies, I don't need 100+ MHz.

    I totally sympathize with you. I'm always looking for stuff to build but there really isn't much complex out there. I would love a little 16 bit computer or something. Something like the replica 1 [] only more complicated.

    Of what I've built, there is one and only one answer. The ultimate kit, the best out there, the Elecraft K2 []. I've built that, the KPA100 power amplifier, the KAT100 tuner, and a few little modules for it. It took me weeks to build it all. It was amazing.

    Kit building is why I got into Ham Radio. The only problem is... I don't seem to care about the rest of ham radio. I haven't operated much. I keep meaning to do more to see if I like it better, but I don't seem to care enough to get around to it. I'm thinking of selling my K2 since it's just sitting around.

    Other than that there are a few kits out there. A Nixie tube clock, while not too complicated, looks interesting. I ran across an all transistor clock [] kit the other day. It looks quite neat.

    You didn't say what *kind* of electronics you want to learn about. Ramsey Electronics has some general-interest kits, as do Jameco and JDR. TenTec has simple ham radio kits (with excellent support), so do Vectronics (part of MFJ Enterprises) and Small Wonder Labs. Elecraft has fancier ham radio kits (multiband stuff more in line with the old high-end Heathkits). And PAiA has audio kits. (All of these companies have obvious website URLs.)

    If you want a stepping stone to building your own digital stuff, most of the IC companies put out really wonderful evaluation boards to show off their parts. They're not kits themselves but they're very much intended to get your juices flowing (the IC vendors want corporate customers to choose their parts to use in products so easy prototyping is vital) so they're easy to get to the "hello world" stage (or the lights-and-switches equivalent) and there's plenty of provision for adding your own stuff to it and then transplanting the whole thing to a free-standing design once you have your rat's nest prototype debugged. Prices vary wildly but some of them are really good deals.

    I'm a huge fan of Microchip PIC CPUs because you don't need to buy *anything*, the programming protocol is simple and well-documented (none of that convoluted JTAG stuff) so you can build your own burner for a few dollars (I use the old "COM84" circuit available on the net, modified to work with the low voltages put out by current COM ports) and free burner software (or you can write your own, it's easy).

    To save yourself frustration and headaches later, DON'T START SOLDERLESS! Learn how to solder first! Flow solder down a long wire. Strip parts out of a circuit board and put them back in without damaging them, without burning the board and checking with a magnifying glass that you don't have any solder tips that cross over onto the neighboring point. Get comfortable removing whole chips using both solder wick and a solder-sucker. Learn the components of solder so you're not wondering why you're leaving "tan stuff" (resin) on the board. Cut several parallel 'wires' on a circuit board and then fix it with solder and a single strand of copper wire ... if you learn how to solder first you'll save yourself the frustration of knowing how to fix a problem but lacking the actual skill to do so.

    I'd look around for kits aimed at high school students. My senior year of high school I took an electronics course where we had to put together a radio from a kit. The good thing about a radio is that there's a lot of cans that need tweaking and points that need to be seen on an oscilloscope to get everything properly calibrated. In fact, this is the kit [] I used (note that I'm not endorsing the seller. I just happened across the product is all).

    I'd go ahead and pick up an electronics text book geared toward college students as well.

    Seriously - make your own kit.

    You need:
    - Plug in solderless breadboard. Get something reasonably big.
    - An assortment of resistors, capacitors, and inductors. Many suppliers sell bags of common values for these.
    - Some transistors: get some NPN and PNP small signal bipolar transistors. Get some N and P channel small signal MOSFETs.
    - A few 555 timer ICs.
    - A handful of 74-series logic ICs (typical quad gates, flip flops, shift registers).

    And of course a whole heap of LEDs. You need some blinkenlights when learning.

    With this you can look at the 'net - for example, while reading 'Lessons in Electric Circuits' [] you can devise circuits to expand your knowledge on what you've just read.

    You also need at least a reasonable multimeter. As you start getting into stuff that oscillates at more than a few hertz, and if you are enjoying what you're doing, it's worth looking on ebay for a reasonable 2nd hand oscilloscope.

    As you get more advanced, you can get microcontrollers, for example, get some Atmel AVR 8 bit microcontrollers - they are supported by GCC and you can make your own parallel programmer with an old printer lead and 4 resistors. Or build a proper computer with external memory - the Z80 microprocessor is still made, and is cheap, and is great for tinkering because it is a 'static' design and run at sub 1Hz clock frequencies where you can see what's happening by putting LEDs on the data and address bus.

    For the basics, you can earn your Amateur Radio Licenses. They require you learn some basic electronic principles that are beyond most of the kits.

    I have played with the kits and they did not help. What I had to know to earn my amateur extra radio license required more knowledge. No morse code anymore, just 3 multiple choice licenses where all the questions are published.

    What you learn is also specific to radios. Filters, amplifiers( sound and power), transmitter and receiver circuits. You learn what it means to apply Kirchhoff's laws. Also to put resistors, capacitors and inductors in serial or parallel configurations. The basics of analyzing power through circuits.

    Most of the above covers analog electronics. For digital electronics, there is a lot of support for digital electronics. The basic stamp kits are great for that. They sell very proven kits, [] with very well written manuals that will take more than a weekend to go through. Also through the make magazine site you'll find project sites for other micro processors used by hobbyists.

    Also, to have guided lessons, a class with lab at the local community college is also a great way to go if you have the time. After all the long winded crap above, if you really want to learn and want more than to look at a board and know what the parts are, this is probably the best way to go.
