Hardware Hacking Projects for Geeks 235

PHPee (Rob Maeder) writes "Scott Fullam's Hardware Hacking Projects for Geeks is an excellent book outlining all you need to know to get started in the wonderful world of hardware hacking. With step-by-step guides to fifteen useful, amusing and off the wall projects, even a novice hacker can be up and running with some basic hacks in a few hours. The book demonstrates various ways consumer electronics can be modified to do things they were never intended to do, and shows you just how much fun voiding your warranty can be." (We mentioned this book yesterday, too.) Read on for PHPee's review.

summary How to get started in exploiting the hidden capabilities in hardware you may already own.

Fullam takes the reader from the very basics of hardware hacking and quickly gets up to speed with some fun and interesting hacks. Projects start out easy and increase in complexity and cost as the book progresses. Hardware Hacking covers many popular hacks we've all seen before, such as the "Macquarium" (Mac Aquarium), a web-enabled coffee machine, and the Blinkenlights building-sized display.

The book is divided into two main parts, the first covering basic hacks, and the second covering more advanced hacks.

Part One:
Starting with the basics, Fullam takes the reader through a crash course in electronics, covering concepts like soldering, using a voltmeter, identifying various electronic components and reading schematics. This section of the book is by no means a replacement for a course in electrical engineering, but it is definitely a solid primer for those of us who weren't born with a soldering iron in our hands. If you've never played with electronics before and don't know the difference between a resistor and a capacitor, this section should get you up to speed fairly quickly.

After the brief basics lesson, the next chapter dives right in to the first project, which is a portable laptop power supply made with a pile of D-cell batteries, a battery holder and some wire. This project is very simple and requires no soldering at all, yet it gives the reader a quick and easy way to make something useful with very little investment in time or money.

Each of the projects is presented in a well-organized manner, starting out with a brief summary and some background information about where the hack originated. A list of necessary tools and materials is also given, followed by a project overview, outlining the major tasks required to get the project completed. Each project outline gives estimates for the cost range, time required and difficulty level for the hack.

After the introductory stuff is out of the way, step-by-step instructions are given on how to assemble, modify or hack the device in question. The instructions are easy to follow and are complete with images or illustrations where appropriate. Many pages contain sidebars that contain additional information related to the project, such as more photos, hints and tips, and links to relevant websites. These sidebars really help to fill in any gaps that may be present in the main text.

At the end of each chapter, Fullam has an "extensions" section, where he suggests ways the hacks can be hacked further, to improve upon the design or alter them to offer more or different functionality. This is one point where the book really shines, advocating the true spirit of hacking and encouraging creativity and experimentation whenever possible throughout the book.

At the end of each chapter is a "Bill of Materials" and schematics for the hack. The bill of materials outlines in great detail all tools and hardware required for the project, including approximate costs as well as sources where they can be purchased.

Some of the highlights in the first section of the book include the "Macquarium," a water-based PC cooling system, and the infamous Furby hack. The Macintosh mod teaches some valuable lessons on using a Dremel tool and working with Plexiglas, which are great skills any budding case modder would want to have. The water-based PC cooling project is one of the more useful hacks presented in the book, showing the reader how to create an inexpensive but effective means to cool down an overclocked CPU. And hacking the Furby to give it a new vocabulary is... well, definitely a great topic for conversation if nothing else. If you have to ask why someone would do such a thing, you wouldn't understand the answer.

Part Two:
Part Two of the book starts off with another more advanced lesson in electronics. It delves into more detail, describing different types of resistors, capacitors and connectors. It also introduces transistors, looking at integrated circuits and surface-mount components as well. One thing I found particularly useful was the section explaining how to read and interpret manufacturers' data sheets for integrated circuits.

The advanced hacks featured in Part Two of Hardware Hacking are a little more exciting than those featured in the first half of the book, but are definitely more involved. The section starts off with a chapter on building a PC-based PVR, using Mandrake Linux. Sample code is included to create shell scripts for a simple, text-based interface, although Fullam does briefly mention some of the more popular GUI-based PVR software available, such as Freevo and MythTV.

Another great hack featured in the advanced section is the "Building-Size Display" hack, reminiscent of Blinkenlights. The chapter starts off with instructions on how to build a display matrix on a much smaller scale, using a series of ultra bright LEDs, but later shows how the project can be expanded to create a 12-story display using an entire building.

Some other mentionable hacks in the advanced chapters include a cubicle intrusion-detection system, an Internet-enabled toaster and coffee maker, and a remote object tracker. These projects provide instructions on how to use more advanced components such as photodiodes, lasers, GPS receivers and microcontrollers (such as the BasicStamp2, in particular).

Two other noteworthy projects in Part Two include a MAME cabinet and a wearable computer.

Plans for the MAME cabinet are very well done, taking the reader through cutting MDF, building the cabinet, installing the software and interfacing the controls to his PC. This chapter goes into great detail, even covering things like creating a monitor bezel and a backlit marquee, and using T-molding for that authentic arcade machine look.

The wearable computer hack is very interesting, covering a wide range of concepts I would never have considered. Fullam gives ideas on what to use for a head-mounted display (HMD), what types of motherboards and CPUs work best, and looks at various power sources, including batteries, solar panels and different generators. The chapter also presents ideas for input devices, such as keyboards and mice, but also speech recognition systems, cameras and GPS receivers. At the end of the chapter, there is an extensive list of websites related to wearable computer projects, offering much more reading to the interested hacker.

The appendixes, while quite brief, do offer more information on topics like creating and editing schematics, using microcontrollers and using different power sources. There is also a list of resources for further reading and a short list of parts suppliers.

Hardware Hacking also has an accompanying website, where readers can download all of the images, illustrations and schematics from the book. The files are available in EPS, PDF and TIFF formats, although they are all gzipped, and are not readily viewable without downloading and extracting first. The website supposedly has code downloads as well, but the links are broken as of this writing, so you'll be stuck typing in code from the book until the site is fixed.

Overall Thoughts
Overall, I was very impressed with this book. Fullam has given the geek community a valuable resource that will provide inspiration for aspiring and veteran hackers alike. It covers many projects that I have personally wanted to build or learn more about, and presents concepts that would be of interest to many fellow Slashdotters.

The only things preventing me from giving this book a 10 are the aforementioned issues with the accompanying website (which I'm sure will be fixed soon) and the quality of some of the photos. Most of the photographs in the book are crisp and clear, but some are rather grainy or pixelated, as if they were enlarged from a website image. Fullam does make mention of the image quality, stating that many photos actually were taken from the original Web sources, and "the clarity of the photograph suffers in print." It's a small point, but definitely noticeable in certain sections of the book. However, as mentioned, the images are available online, and often do look better on a monitor in full color, as opposed to the black and white images in the book.

I highly recommend Hardware Hacking Projects for Geeks to anyone with an interest in those fun projects that only nerds can understand.

      Yeah, I also remember the days when, for me at least, all I needed to build a boat was a pile of wood and desire.

      I am, nonetheless, greatful that Howard Chapelle took the trouble to distil the combined wisdom of boatbuilders into his books. Thus I get to spend my time building more sound boats while playing with new ideas instead of wasting it recreating what is fairly "common" knowledge.

      And sometimes a book/how to can simply serve as inspiration to get you going. That is a valid function as well.

      You're kind of missing the point then. The goal of these books is not to "commoditize" hacking, it is to give those with an interest in the subject a foot in the door to the world.

      It's no different than a betty crocker cook book. The recipies are there to illustrate the basic skills and information needed for the task at hand. It is left to the reader to expand that knowledge into their own recipies later on.

      Many kids these days are growing up in a world where everything they own is a black box with mysterious circuit boards and a few wires inside. Long gone are the days where a kid would be given one of those "build your own radio" kits, or a computer is shipped to you as a box of parts. Exploring the innards of a device is considered backwards now, and even frowned upon.. you're instead supposed to just throw it away and buy a new one if it breaks. Many electronics are so complex anymore that a newbie trying to extract interesting pieces and doing something with them results in useless slag.

      Don't view this book as cheapening your "hacker status".. but view it as an effort to open up the world to people that aren't part of it.

      Anyways, you do realize the liability aspects of a project like that, right?

      I mean, it's one thing to point people over to some fun hardware diddly doo, but it's something else for people to start messing with fairly high capacity bateries and chargers for such.

      I guess what I'm saying is that, it is actually possible for someone with more than half a brain to (unintentionally) mess up the project you are describing and do a significant amount of damage.

      I'm normally not the first person to get worried about stuff like that, but I'd hate to see a battery blow up in someone's face. You should probably at least make people aware of that possibility.

        Absolutely.

        It is dangerous any time that you are using 24 volts at 5 amps. Plus, there are capacitors inside of UPS's and, if you're not careful, there are wires that you may think are dead that are live.

        As a general rule when ever doing something like this, there are some ideas that I try to follow:
        1.) Use fuses. On a setup like a 5U APC UPS, you're going to have a 20 amp wall circuit and 48-52 volts on the batteries. I always put a 100A fuse in the middle of the batteries. It may not prevent catastrophies, but it might, and it just feels safer.
        2.) This is a reason that I really like the plugs that come with the APC UPS's. They are able to be plugged in without sparking and without touching wires, etc. Very solid. So use connectors that are shielded (like shielded spade connectors on the Tripplites or specific plugs on the APC's), and use electrical tape anytime you do anything like connect two wires. Doing a google image search, I came up with this as an example of the connectors that are in the APC's: it's the yellow thing [platan.ru], although this isn't quite it, but it's close. The connectors are made by Anderson Power Products, and they're rated for 600V at 50A.
        3.) Wear gloves, work on carpet (not on concrete), don't ground yourself, wear rubber-soled tennis shoes, etc. Obvious stuff.
        4.) Use wire designed for the amperage you need. For 5 amps, you don't need a HUGE wire, but for the rackmount stuff where it's possible that you'd be pulling 15-16 amps, you need big wire. Stranded copper works best, because (i think, this could be wrong) amperage travels along the outside of wire. Figure out what size wire you need, and go one bigger for safety. We use 10AWG for the rackmounts, cause that's what they use on the inside. It might be 8AWG, i'm not sure. I know they use 10AWG in the APC SmartUPS rackmounts.

        It takes a bit to make a battery explode. It's not that common. But ALWAYS, caution is in order.

        Also, as long as we're disclaimering, obviously this is dangerous / voids your warranty / should be only done by trained professionals etc. The guy who taught me how to do this was my boss (the guy that owns Netmar, Cengiz Akinli), who has taken numerous electrical engineering classes at Virginia Tech (he's mostly done with a triple aerospace engineering / math / physics degree). So, while yes this sounds risky, it can be done safely, and we've worked all this stuff out mathematically, too, as well as having put it into use in real situations for several years.

          That is only an issue for high frequency (Mega- and Gigahertz) applications, where you have the so-called skin effect. But there, it will not help if the strands are touching each other, since the whole thing would look like a solid to the rf anyway.

        What liability? Lawyers should be herded, summarily executed, dried, powdered, and used as fertilizer. Basic knowledge and the awareness of existence of Darwin Prize should be enough.

        What's much more detrimental to experimenting and playing with cool toys than people complaining about "hacking cookbooks" is the pervasive fear of liability and lawyers.

        I hate disclaimers.

    • I agree, you should have included a disclaimer or something to that extent.

      Anyway, i like this project, it does sound like a very novel idea, but my question to you is will the new battereies overload the charging circuit (transformers, inverters, caps...), and even more so what will happen when the power does indeed go off, will it melt the wires (if they're lower gauge)or even freeze the relay? And finally :) will it mess up the onboard battery health monitor/diagnostics?

        UPSes are dumb. They're not controlled by microprocessors, they don't have an intelligent learning capability, etc.

        When a UPS is charging, all the UPS knows is "hey, those batteries aren't pushing back as hard against my current, so i'll let current naturally flow to them". It does this until they are at sufficient voltage. Period. There's no timer or anything. And I say this, but I don't mean that *no* ups has none of this intel

      So instead of telling yourself that you are buying a book, tell yourself your buying the results of someone's research.

      Your assertion applies to 99.9% of non-fiction published in the last five years anyways, but people continue to buy the books. Ever occur to you that the compilation and presentation of all that free material in a coherent informative package is something of worth in and of itself?

      In point of fact you do the author a tremendous diservice by trivializing the work in such a fashion. Let me propose a little experiment, you take tomorrow with google, a few hours with LaTex the next day, and none of us will hold our breath waiting for your publishing contract. See the point? You hypothesize that creation of the work is nothing more than collecting stuff off websites amd stuffing it into a pdf. I'm suggesting that would never have been published. First off, most websites give professional editors fits, if you want to make an editor think you're incompetent, then stick wsith the plan you suggest. If you want to thought of as a writer, understand that most of the job is going to be taking that flood of google results and turning it into material fit for the printed page.

      But wait, there is more... What about those websites that google turned up? That site that talks about teaching your TiVo to fetch your pipe and slippers for example. Did that site try to present the information clearly and completely, or did the author assume a bunch of knowledge on your part? Were any procedures provided likewise described? While I don't doubt that all the info is available, is it all consumable?

      Like the other reply to this, I also have to ask if it is as trivial as you pretend, where is your Hacker's cookbook? And I'm guessing your Pullitzer prize is in the mail? I for one recognize that it isn;t that simple, and I have neither the time nor the temprament to undertake such an activity. Will I buy his book? No. Like you I will go to google and undertake essentially the same process you would, or the author did. However, I don't disparage the process, or that the author has obviated it for those willing to pay for the privilege. I personally feel that the process is part of the experience, and often the source of new ideas to explore. However, that in no way imparts any license to disparage the author's work, or to trivialize the process by which it was created, since it is essentially a macrocosm of the process each of us would apply to that same material. The difference being that when you or I do it, we do it for an audience of one, an audience, I hasten to add, we are intimately familiar with. The author undergoes that process for an audience of far larger than one, and without the benefit of familiarity.

      Now re-read your first post, is this a skill you think you really have? Is that how you preent information effectively? Hell, and your audience was just /. members, a group you have some familiarity with....

      To update an aphorism:

    Make a Tattoo Gun

    Things you'll need:

    * bic pen (this is your tube that houses the needle)
    * 4 or 5" section of guitar string ,second one from the smallest. ( this is your needle)
    * tooth brush ( this gets bent like a "7" and joins the pen to the motor)
    * an eraser from a pencil (this joins the shaft of the motor to the needle/guitar string)
    * small battery operated motor (from a "walkman" or a hand held fan)
    * some tape (to join everything together)

    Putting the pieces together:

    1. Take the guitar string and bend a little bit of the end down or up.
    2. Take out the ink tube of the pen, and cut it to about a 3 or 4" length, now file down the brass tip of the pen to get the ball out, make the hole big enough to allow passage of the needle.
    3. Insert the needle into the pen.
    4. Now take the tooth brush and cut off the bristles making it about 4" long. Heat it up in the middle with a lighter and bend it in to a "7" and hold in place untill stiff.
    5. Join/tape the pen needle assembly to the tooth brush.
    6. Now take the eraser from the pencil and shove it onto the shaft of the motor, try to get it as dead center as possible. Join the pen/needle/tooth brush to the motor/eraser assembly, tape the brush to the motor.
    7. Take the bent part of the needle/guitar stirng and stick it into the eraser, IMPORTANT- the needle must be purposely OFF CENTER.
    8. Now all that is left to do is find a power source, I used the plug-in adapter frrom a cd player. i guess you could hook up some batteries to a switch and then to the contacts of the motor.

      I once had to rig a replacement battery for my PDA using a pocket knife and sewing kit, in the waiting area at the gate before a long flight to Europe (which the PDA's backup battery wouldn't survive). Fortunately this was back in the blissful 1990's, and I was not subjected to indefinite secret detention as an enemy combatant.

    I'm not really a "geek," nor do I play one on TV. But after looking through a book like this, I might just be motivated to try and become one. This book is one that appeals to the "mad scientist" in all of us, the one that is always looking for ways to build the better mouse trap or the perfect home "do it all device." While some of us less "handy types" would be better off not coming anywhere near this book, there are enough projects listed here that even someone with little or no hardware experience would find at least a handful of projects doable. Projects like the "Macintosh aquarium" or the laptop PC power supply. In fact the book is divided into Basic and Advanced Hacks and techniques, so if you've started off with a couple of the basic projects finished, you can move on to more advanced ones. Very cool.

    And for each project, there is a graph for project cost, time and difficulty on the beginning page. For some projects, there's a list of what items you will need. There are also extensive step by step instructions for each "project," along with drawings, photos and diagrams. You'll love this book if you're one of those people who loves taking apart products and trying to "improve" upon their original design.

    With all the related stories recently, I found this link to hacking your own high quality streaming audio via telephone [negativland.com] for use in 'tele-touring'.

    It looks pretty easy to make, albeit rather narrow use? Very interesting. That whole site should be required reading for /.ers. ;)

    I changed out a CD player in a car with an mp3 capable one. The GF wondered where her favorite CD was, and I realized it was still in the player I'd pulled out, in the closet. What to do? I looked around and found a power supply brick with 12v, slipped it over the power pin of the player, used a screwdriver to connect the ground, and the eject button popped it out. No dissassembling the dash again, or messing with alligator clip leads.

    (It certainly counts as a quick fix for a botch -- i should have popped it when it was still in the car).

      I'd rather consider that as common sense rather than "hack", something that works with 12V (dc) supplied by a car battery can be fed with any 12V (dc) source. even a no-brainer can figure out how to shrtcut the ground with a screwdriver and pop the cd out.Hell, most in-car cd players when they are connected for the first time pop the cd tray/mechanism out to take out the protective piece of carton they have for shipment protection. Duh !

    Build an electric motor from a few items that you probably have around the home or office. I think Beakman did it first but instructions can be found here [ntnu.edu.tw] as well.
    • Great, this is a copy of my original page of instructions located here [hiwaay.net]. Probably at some time I may have given them permission to copy or link to the site, but I did ask that they reference the original page (which they do not seem to have done).

      BTW, this was the first public web page I ever created -- way back in the dark ages of the web. I need to fix the broken links, counter, and my (really) old e-mail link :-(
      • Where did you get the idea? Other comments indicate that this did not originate with Beakman so I'm curios to trace the origin of this concept.
        • Well, *I* got the idea from watching Beakman's World. I can't find the e-mail (it's been a long time), but I received a mail from Jok Church, the guy who created Beakman's World, and he told me that the design originated back in the 1950's and that variations had been published in different places. This was in response to whether I could post the instructions on the web or not. The general consensus was that it was essentially in the public domain and that he didn't mind me posting it as long as I attrib
    • I did a similar project in 5th grade... Paul Zaloom (aka Beakman) was not the first. Though his show definately kicked ass.

    I have hacked up an old phone and connected it to my PCs parallel port. This, in combination with a perl script and a couple other programs, results in a machine that waits for calls with "UNAVAILABLE" or "PRIVATE" Caller ID tags, answers only those calls, plays prerecorded wave files designed to emulate a conversation, uses silence detections to allow the telemarketer to speak and think he's talking to a real human, and records the entire conversation. I have example WAV files of these conversations and a How-to page at http://www.pagerealm.com/tc2k. The example WAVs are VERY entertaining!

    Really simple, all I used was a soldering iron, solder, blue LED. You can pick everything up at the local Radio Shack. The Radio Shack I visited had 3000mcd super bright blue LEDs. I eventually bought a 9000mcd super bright blue LEDs but I found out later that it's super bright coz the manufacturers tighten the angle of projection meaning brighter center spot thus higher mcd. 3000mcd still works well. My first concern was whether the LED was brighter than the normal red LEDs since they are on different ends of the wavelength and red is easier to pick up. Didn't really matter if you have a good enough pattern or surface, like a mouse pad made for optical mice.

    I modded my blue Logitech Optical Mouse (USD$20 the last time I checked). Removed the regular red LED and replaced with the blue LED. Now my mouse glows blue. Looked kinda weird previously coz the mouse was blue, with semi-transparent blue plastic but glowed red underneath.

    Easy modding... takes less than 15 minutes, unless you lose a spring or something.

    There's been a hack out for a while where you can remove the DVD drive from certain models of APEX DVD players and replace it with a hard drive full of SVCD movies. With a 250 gig HD, you should be able to fit a couple hundred movies on there.


    The caveats are that you have to swap the hard drive in and out of your computer to add more movies, etc. But the plus side is that it's a pretty easy hack and you get a real remote control, nice form-factor, etc. without having a noisy, hot computer in your living room to serve movies.

    Here's a link to the hack [area450.com].

    I think that description of the hack talks about adding a seperate power supply, but I've heard if you don't keep the DVD player in there and only put a hard drive in, you can get by on the original power supply...
  • I got a copy of this book hot off the presses, and while overall it's good, the first printing has some quality-control issues. The centerpiece of the first real chapter, the "basic electronics" chapter, is a big schematic diagram with various points labelled "A", "B", "C", etc. up to "K" or so. Unfortunately, the text spends several pages referring to these as points "1", "2", and "3" -- either the text or the diagram must've been changed at the last minute, and they don't correspond!

    I bet this will be

    I was contacted by the author of this book last year and gave him permission to use my plans for building a Macquarium. So, I am chapter 2 of the "Hardware Hacking Projects For Geeks" book.

    Woo Hoo!

    Anyway, my aquariums are Here [techquarium.com].

    The plans Scott used for his book are here [techquarium.com]. The plans are kind of old and busted (there's no link to them any more on my site) and I think the author did a great job.

    The one thing in the book I'd like to build now is the MAMA game cabinet. I've got an old arcade Ms Pac-Man and it gets lots of use but I'd love to have a bunch of the old games in one stand-up cabinet.

It is easier to write an incorrect program than understand a correct one.
