What (non-PC) Hardware Do You Hack? 696

Lis writes "Mike Langberg at the Merc News interviewed Scott Fullam - Scott wrote the book 'Hardware Hacking Projects for Geeks' which includes things like a video periscope for your car, an Internet toaster, Cubicle Intrusion Detection Systems, and talking Furbys. (Instructions for the toaster and coffeemaker are up on the O'Reilly site.) Almost any kind of consumer electronic equipment can be modified to do things it wasn't intended to do. Ok, you'll probably void your warranty in the process, but you could end up with something even better than the original. Or not. But it's just gotta be interesting. So what have you hacked, and into what?"

      I don't know that following the IKEA directions counts as hacking.

      Now if you used all of the leftover pieces that for some reason you didn't "need" in the rebuild to create pulley system that saved you some trips upstairs (or an IKEAbot to do the work for you)... now *that* would be hacking.

        Here are some ideas and suggestions for those who want to hack the U.S. woman culture. The first thing you should know is that hacking your own culture can be scary. It's definitely an E-Ticket ride, for those who want to tackle something seriously complex.

        Bitching is part of the American woman culture. It cannot be disabled. For a better experience, try a different nationality. In the U.S., the word "bitch" means both "complain" and "woman". Did you know that there are no other English-speaking countries in which this is so?

        This is a bit extreme, but a good exaggeration might be that if you have only known women of the U.S. culture, you have never really known a woman at all. Women in the U.S. commonly: 1) are infantile, 2) live in a fantasy world in which the rules of life don't apply to them, 3) are self-destructive, 4) want control, 5) believe that men are reponsible for all of their problems, 5) are irresponsible to an amazing degree, and 6) use anger and hostility to try to intimidate and get their way.

        Want examples? Read the women's magazines on any newstand in the United States. Watch some of the episodes of the Oprah Winfrey show, in which men are seen as the objects of fantasy, or as inherently evil enemies.

        If there are any readers who want to give an instant negative reaction to this, please think carefully first. I've traveled to 33 countries and talked with hundreds of women extensively from other countries about their lives. I'm serious about understanding the problems. Ask yourself, are you? Do you really care about what happens in your country?

        When I lived in England, it was common to see English and European movies in which there would be a comedy episode in which an American woman did something selfish and out of touch.

        That said, the American woman culture can be successfully hacked. It's a limited kind of success, like living in a cesspool and saying that you like the brown things that float past better than the black ones.

        First, don't take American women seriously. That gives them responsibility and they don't like that.

        Second, don't depend on them. They may want sex with you today for no good reason, and not want to talk to you tomorrow, also for no good reason. A Russian woman said, "It may take me only one minute to fall in love, but I have to be in love to want sex. American women sleep with anyone." I've heard that from people of several nationalities.

        Third, don't blame everything that happens in your relationships with U.S. women on yourself. If you did something bad, accept that. But recognize that a common way for a U.S. woman to get control is to try to get you believe that you are an inferior kind of being.

        Fourth, spend considerable time understanding the U.S. woman culture. It is, in many ways, not what it pretends to be. For example, women in the U.S. often project confidence, when they don't feel confident at all.

        Fifth, stay with what is logical. Logic has little importance for many U.S. women, even those who are successful in the U.S. computer industry. If you stray away from what is logical, you may soon be as confused as her.

        Sixth, treat women right even if they treat you badly. Everyone needs more experience in learning how to be good to themselves and others. I'm not religious, but it happens that Jesus Christ was right: Don't answer violence with more violence; don't answer bad behavior with more bad behavior. Like it said in the movie, "Bill and Ted's Excellent Adventure", "Be excellent to each other." Being excellent to women does NOT mean spending money on them. You should each contribute equally to your relationship. If she doesn't want to do that, she doesn't want a real relationship.

        The U.S. is suffering a social breakdown. The breakdown is caused in part by the largely hidden breakdown of the U.S. woman culture. When a man cannot find a suitable woman friend, when a man and a woman cannot make a stable relationship, wh

          I have mod points, and I very nearly modded this flamebait.

          But I've realized (after careful reading of this post and some perusal of your website) that this isn't flamebait or a troll, in the usual senses of the words, and that you seem in some ways to be a very thoughtful individual, if rather misguided about some issues.

          So I'll rebut your arguments instead.

          "Bitching", defined as complaining, is hardly a pursuit limited to women (american or not). I've worked in male-dominated (not purposely, just because it fell out that way) offices that held 'bitch sessions' that were called exactly that.

          The use of 'bitch' to denote all women is a misogynist term, and almost certainly did not originate with women. The more or less male analog to this is 'bastard', yet not all men (american or not) are illegitimate.

          > This is a bit extreme, but a good exaggeration
          > might be that if you have only known women of
          > the U.S. culture, you have never really known a
          > woman at all.

          Just for the record, my mother is Japanese, as is her mother. So I grew up with women who were not socialized predominately in the U.S. While I have not been able to leave the U.S. as an adult, I have certainly dealt with women who did not grow up here. So this argument does not apply to me.

          > Women in the U.S. commonly: 1) are infantile,
          > 2) live in a fantasy world in which the rules
          > of life don't apply to them, 3) are self-

          > 5) are irresponsible to an amazing degree, and
          > 6) use anger and hostility to try to intimidate
          > and get their way.

          Oprah Winfrey and Women's magazines in general are not indicative of 'women's culture' any more than esquire, playboy and sports illustrated are indicative of 'men's culture'. They are corporate entities created to make money. Nothing more, nothing less.

          So, unless you would like to try to claim that men are 1. infantile, 2. live in a fantasy world in which the rules of life don't apply to them, 3. are self-destructive, 4. want control, 5. believe that women are reponsible for all of their problems, 6. are irresponsible to an amazing degree, and 7. use anger, hostility, violence and a larger body size to try to intimidate and get their way. I'd suggest you either reconsider your sources or reconsider your hypothesis

          Incidently, all of these things are true for individual examples, regardless of gender. None of these things are true for the entire gender.

          I fail to see a problem with some of these things ('want control' -- I want control over my life, and I fail to see why it's wrong for a woman to do so) and some of these problems (irresponsibility, blaming others unreasonably, intimidation) are problems in American culture, period, and are not particularly gender linked, though the way they manifest may be, i.e. statistically, women will be more likely to use emotional manipulation, like crying, where men will be more likely to use physical intimidation. But this is still statistical, and any individual may use either or neither, regardless of gender.

          Also, these traits bear startling resemblance to the psychological profiles of a healthy woman (as in, this is what a psychologically healthy woman is like -- a woman who acts as an adult, is responsible, likes men [and therefore sex], etc is neurotic and requires treatment) from the first half of the twentieth century. If you are not aware of this you may want to do more research here. A fair chunk of women's problems in this country stem from psychological and psychiatric practices.

          And yes, I really do care about what happens in my country. Which is one of the reasons I hate seeing energy wasted on misguided attacks and other strategies.

          I fail to see how the satiric practices of any country accurately reflect the reality of any other country reliably enough to draw good conclusions about that cou

      Would it be hacking if you just took off the shelf (either stock or aftermarket) and installed them? Or would you have to kind of cobble together something that's rarely normally done for it to be hacking?

    When i was in high school there was a particular big dumb jock that would pick on me. It was a catholic high school. So I stole some official letterhead paper from the guidance counselor's office and an official envelope with the school info on it.

I made it sound much more official. Had my friend forge the dean's signature, and that if they (his parents) had any questions about it, feel free to call (phone number included).

    Then I mailed it.

      Well I have a situation with a particular arsehole at work who actually complained to higher management about me using *his* coffee up, so I take revenge when ever I feel like it.

      I hack into his Windows machine and kill the WinLogon process. Then I jump up and go make coffee - looking all innocent! It takes 5-10 seconds before the machine just reboots. He's reinstalled Windows 4 times so far and changed most of his hardware. I let it go for a week or two between reboots to give him the impression that a rebuild actually helps things.

      I try and time these events with his lunchtime game playing or when he's lecturing a junior on how good his software is. (During his good programming lectures I selectively kill OLE processes, causing his app to fail with access violations.)

          Conversely, it can be fun to work in an office of old-time Win weasels, who know nothing about Unix, but manage to have much cooler workstations than I do. A simple amusement is to wait until they have someone in their office (or on the phone) to whom they are loudly bragging about their technical prowess, and then telnet in and run some nice .au like a toilet flushing.

          BTW, our Sun systems have the flush.au installed by default in /usr/demo. I always thought this was very considerate of them, but I do wonder what the intended use for it was...

      I find that unlikely. Among other quirks, the Apple Lisa has a home-grown MMU, developed in house by engineers who empirically determined what 68000 instructions could be restarted after a page fault, and how. The 68000 was not designed for virtual memory, you see, so the Apple folks had to experiment and create their own software and hardware to make it happen.

      I would be surprised if anyone put that much that effort into a class. If you built a 68k computer with a bitmap display, then you have something there, but it's not a Lisa. Don't think that just because the Lisa came out before the first Mac that it's a more primitive system--in fact it's quite the opposite.

    And it's nice to know that my dreams of Internet toast have been fulfilled.

    Anyone with a little skill/determination (yeah, that's a slash, not an "and") can hack anything; I think a more interesting article would be about maverick hacks that actually turned out to be useful. Like, say someone turned a toaster into a door-to-door salesman irradiation device. That would be amazingly useful.

    I once dremeled a PCB from an old power supply into several pieces, then resoldered and glued it back together so that it still worked, and tried to sell it on eBay as modern art. Unfortunately, no one bit. An interesting hack I've seen is something I think a lot of electronics slashdotters out there should note: Cheap oscilloscope using your sound card. The software is available on the web, just get your signals into at +/- 1 or 2V range, and you have a dual channel low frequency scope that plugs into any sound card. Check the voltage range of line-out to get an idea of what's acceptable. I started making an adapter to provide a high impedance input and scaling the signal down, but got distracted and haven't revisited the project in a while.

    Recently I've been studying up on electronics and modifying the electrical components to my basses. If you're a geek and into music this can be a lot of fun. It has the added bonus of helping you as a musician really understand every single part of your signal chain.

    There are several reasons why this is cool. The components of a passive pickup system are real simple, allowing you to get started easily. As you build up your base of knowledge you can get involved in much more complex projects, like modifying amplifiers, building your own stomp boxes, etc.

    Another reason this is a cool field is that you can approach it from different angles. If you're good with calculus you can design and calculate the frequency response of your filters before you build them and know exactly what you're doing. You can design a whole effect if you want and model it in circuit modelling software. In fact, with some programs I believe you can do that and use a wav file for input to get an idea of how the circuit will sound, although I haven't tried that myself.

    If you're a physical experimenter kind of a person you can take existing circuits and see, for example, how a tone knob sounds different when the pot is connected to different values of capacitors. Plus, if your favorite part is building, not designing then there is a huge amount of free schematics for things on the web, kits you can order, etc.

    It's loads of fun (pun intended?) and you can really individualize your sound (for better or for worse).

    not quite an electronics hack, and not quite a full modification... more like a hacked add-on accessory...

    When the Hasselblad Xpan (makes 24mm x 60 mm panoramic frames on 35mm film) was first marketed, I drooled over the ads, but didnt have the budget for it.

    But I did have a medium format Rolleicord TLR (which makes 60mm x 60mm frames on 120 film), and I knew that a 35mm film adapter existed for it, so I shopped around used camera store until I found one that had kits.

    Now the full kit prevents you from not using the 35mm mask (to make 24mm x 36mm frames).

    Luckily, the store manager had an incomplete kit, which I got at a substantial discount from a complete (collectible priced) kit.

    So I used the two parts that serve to hold the 35mm film canister, and used some medical duct tape wound on either end of a 120 film spool to narrow the space for the 35mm film and voila!

    Cheap "real panoramic" 35mm photos.

    The only downside is that I have to rewind the film in a changebag or in a darkroom.

    Back in college, I used to love synthetic programming [hpmuseum.org] in an HP-41C. When it was first discovered, one had to use various evil processes (yanking a memory modules, corrupting a magnetic card). The result was programming instructions that HP never intended. With synthetic programming, one could access hidden memory locations, display strange characters, and emit unusual sounds (just be careful with "STO c"). I spent way to much time exploring all of the tricks and documenting what did what.

    My favorite little synthetic program made the machine tick ominously like a Geiger counter.

    It was my first electric motor. I was about 9 years old and had extracted my first electric motor from some doomed toy, and figured out how to attach wires manually to the brush leads and a battery and make it run. Unfortunately, as with most things I played around with at that age, I didn't know much about cause and effect.

    I believe the motor was originally driven by two 1.5 V AA batteries, and I was using a 9V. (Hey, it's easier to connect!) My plan was to use it as a climbing winch, enabling Snake Eyes (tm) to sneak up on the evil Destro(tm)'s clifftop lair. I tied one end of a 3 foot piece of sewing thread to the motor shaft, and the other to Snake Eyes' left hand. I wedged the motor under a book and connected the battery to winch him to the top!

    Little did Snake Eyes know what kind of evil Destro had in store for him. Little also did I know - it happened so fast that I am still fuzzy on some details. At some point, Snake Eyes stopped standing on the ground at the base of my dresser and entered into a state where he was spinning at insane velocities about the motor, attached by a tangled 6 inch piece of thread. I have no memory of a transition between these two states.

    The moral of the story - if an evil overlord leaves an electric motor conveniently located for you to winch your way up the cliff face to his mountain fortress, don't use it!

    Within weeks he had his unit all wearing beards.

    He arrested a senior member of the army who came back to the base too late after a night out.

    And the best bit: In the army one's transport to and from home each weekend is paid for. He lives the other side of Europe from Italy, so they offered to fly him. But no - the rules state that it had to be by train (which takes what, a day? a day and a half?) so he ended up spending just a couple of days a week in Italy...

    They sent him home soon afterwards. Nicely. Permanently.

    Ever notice how it's so difficult sometimes to wake up when it's dark outside? It seems that I'm at higher risk for getting up late when it's overcast or stormy outside. It seems that the light level triggers how awake you are. If I have to wake up early, I'll usually leave a light on in the room; it helps a lot. But it's not the best solution, and I'd love to smooth out the roughly torn edge between sleep and consciousness when the buzzer screams at you.

    I'm building a clock that includes a wall socket. You plug a lamp into the socket, and half an hour before your set wakeup time, the lamp begins glowing. It increases brightness gradually over a half hour so that by the time you need to wake up, you already are. It's not really a new idea, but it's fun. It uses a realtime clock chip, a microcontroller, and a triac for power control. Maybe not so much hacking...I guess it does "hack" a desk lamp into a wakeup alarm notification device.

    Most of my other hacks are computer related; for example hacking a Sandisk 6-in-1 memory card reader to work with ALL CompactFlash cards, instead of only the new ones, with a single wire. I hacked a Nintendo R.O.B. into an internet-controlled pan/tilt webcam mount [macetech.com] in an hour or two. Also ran a small server in college which used fetchmail to check for new messages, and would flash one LED over my desk and one in the door's peephole, so I knew I had mail just by looking down the hall from a friend's room. Lots of random stuff like that. My most recent major project was a small CNC machine, the computer, power supply, and driver electronics housed inside the case of an old Yokogawa data analyzer.

    PIC processors can be insanely useful for this sort of thing and very cheap (most around $10) and easy to get, and once you've got the basics down (which can seem a bit daunting at first) they are very easy to learn and program to do pretty much whatever you want. The playstation mod chips are cheap miniture 8-pin PICs usually - just to give you an idea of what they can do, and some of the more advanced models have RS232 (i think) builtin so you can directly interface it with your PC. Add to that some cheap easy to use wireless modules (they just take a power supply and you stick the on/off binary signal in and thats all you need, takes 2 minutes) you can do some nifty remote controlled things. Basically anything from just switching something on and off or blinking some leds (which can be programmed in minutes) to full fledged computing can be done with these babys. They have loads of extras too - analog-digital converters, eeprom memory, high-current switching and more.

    I was gifted an Mp3 player that came from China. Unfortunately, it also came with Chinese instructions (though the unit had English on the display and buttons) and a 200-240V adaptor (5V 600mA output).

    This was a fairly sensitive unit, so I wanted to be careful about the voltage. A decent step-up transformer for 110-220V is around $70 here. It's also not as easy as one things to find a decent priced 5V/600mA adaptor (most are about 300mA, and not all that "stable").

    I eventually came to the bright conclusion that computer power leads have a 5V connector, so I made an adaptor for the front of my PC. I then removed the original 200V adaptor and simply connected the power lead to a plug that fits in the PC. Viola, my MP3 player now charges nicely and plays tunes while I'm on the go.

    Bear with me here, this is legitemate and not a joke.

    After hours, the desk attendant is replaced by a rent-a-cop. These rent-a-cops, to make things convinient for themselves, are in the practice of comandering one of the elevators so that it only moves when they put their key in.

    Similarly, the cleaning people, when moving from floor to floor, leave their wheeled carts on the elevator and disable the movement of the elevator to save them the trouble of waiting on an elevator and moving their carts out of the elevator.

    This has, at times, annoyed me. So I figured out that if I enter the elevator and [b]hold down[/b] the floor button, the elevator door will close and I will move to my floor.

    This mischief of mine is mostly directed at the rent-a-cops because when I enter the building it is easist for me to just grab their elevator and ride it up, leaving them thinking that they didn't set it right.

    However, the bigger impact is on the cleaning people, for when I take their elevator, I'm also taking their wheeled carts, and it must be a pain in the butt to try get back that elevator (one of three). I mean, they push a return elevator button, and it's 1:3 chance that it will be the right one.... every time! Because of this, I'm much less likely to hax0rz their elevator.

    I saw a comedian the other day on Comedy Central who made fun of the good ol' Speak & Spell. He could almost duplicate the voice from that wonderful learning tool and said things demonically like, "A, B, C, D, E, F, G... I will eat your family." Very funny skit, but it also reminded me of a "hack" I did to my Speak & Spell when I was 6 or so that awakened the true demon of the dictionary.

    I had one of the original Speak & Spells with the raised-button letters (unlike the later models that were completely flat). On all Speak & Spells there is a "Code" mode where up to 8 letters can by typed and transposed into a code that only people with other Speak & Spells could decipher (ROT13, or something else very weak). One day I grew bored with this mode and leaned on all of the buttons at once. This caused the multi-directional character LEDs to all light up like 8 little boxes. I then started pressing the apostrophe key. Each box would turn into an apostrophe. Boop... Boop... Boop... Boop... Boop... Boop... Boop...

    As I pressed the apostrophe key one more time to erase the last malformed chaacter, I awakened the demon within the Speak & Spell. All of a sudden the Speak & Spell went into the "Say It" mode where it would teach particular words. Normally, it would show a word like "OCEAN" and the speaker would state, "Say it... OCEAN." But in this crazy mode I had put it into, the speaker would shout incoherently. "Say it...HUGAXCKHUAAAHRETA!!!" It would keep on doing this, screaming incoherently until the enter key was pressed, at which time it would pick a random word and shout it out. "MOTHER!"

    It definitely made my parents laugh, and the same Speak & Spell works to this day with the same bug. Keep in mind that the Voyager space probe also had less memory than a Speak & Spell, too...

    About 20 years ago I 'hacked' a car LED clock module by wiring some ribbon cable to the relevant parts of the PCB and mounting the unit with a 12V transformer+PSU, programming switches and a 10A mains relay in a small case - the end result was a unit into which I could plug my coffee percolator and have it 'brew-up' at the pre-set time in the morning! Because it also had a 59min count down timer, I could also set the coffee brewing at other times knowing that the timer wouldn't let the percolator boil dry!

    My most recent hack was to make up a short lead that runs from a universal (90-250v) multi-voltage 2A DC power supply. On the 'output' side of the lead is a 12V car 'cigar lighter' socket into which I can plug a Belkin 12V 'car' to 5V USB socket adaptor - now with the relevant leads I can charge my phone or PDA or use anything else that normally takes power from a USB port - this means I only have to take one power unit with me on holiday or on business rather than one PSU for phone, another for PDA, another for digital camera, NiMh battery charger etc.

    So one night, with more free time than is strictly healthy, my friend Steve Roche and I were sitting around microwaving things, when one of us decided to set the time on the clock to "6:66", just to see what would happen.

    Fortunately for us, the programmers of the firmware didn't include any validation code, because it let us set the time to 6:66. We sat there for a minute, debating what would happen next. Would it change to 7:07? 6:67? 6:07? 6:67 it was. What would happen, then, after 6:69? Again we debated -- would it go to 6:70? By that time we sort of assumed it would.

    Well, it fooled us but good -- after 6:69, it invented a new number . The display read "6:6^", or something like that. We watched with fascination as it made up five more brand new digits, before changing to 6:70.

    Then we microwaved some wormy flour, which stunk up the house in some awful, indescribable way, and ended the microwave experiments for the evening.

He had just installed a new stereo, but didn't complete the job, so there were all sorts of loose wires hanging from under his dash board.

When he got out of work that night and started his car, things got pretty amusing. At first he couldn't figure out what was going on, then once he realized what was happening, he started banging around on the horn to shut it off. He finally managed to get the horn to shut off by knocking the ground wire loose, unfortunately, since power was still running to it, it went off everytime he hit a bump. He drove about 5 miles home with that horn going off under his seat, needless to say, he didn't think it was nearly as funny as I did.
