Keep your kids in line with a time clock

When the cat’s away the mice will play, but a least you’ll know when they came home if you use this time clock. It’s called the Kid-e-log and [John Boxall] developed it to help a friend who wanted to keep track of their teenage children’s after school activities while they were still at work. He figured having them punch a time clock would at least let you know if they came straight home as they were supposed to. An RFID tag was issued to each (no, they didn’t implant the tags) and used to record the time. To keep fraud to a minimum the hardware has a battery back-up for its real-time clock, and the tag read events are stored to EEPROM for retention between power cycles. This doesn’t prevent common tricks like taking the reader with you, or sending your tag with a sibling, but it’s a start. See it in action after the break.

    How about adding some TSA-like pornoscanner capabilities, to add insult to surveillance…

  • Steve says:

    Wow, smother much?

  • Onaka says:

    Now get some electronic locks for your doors and integrate this system with it and embed it in the wall.
    Now only allow the doors to be opened with a valid RFID tag.

  • Roon says:

    If you used a fingerprint reader instead of an rfid tag you wouldn’t have to worry about some else using the tag… unless they chopped their finger of which seems a bit extreme.

  • Pat Hartl says:

    Or you could just implant it. You could also have a rockin security system if you implanted everybody in the family with some tags. I’d do it!

  • Mitch says:

    Talk about control issues! Bet this same clown has GPS tracking on all of their cell phones too. Oh, and lest not forget a full profile for each of the kids play buddies.

    Smells to me like these are some kids that are gonna need some serious therapy some day!

  • Ben R says:

    Nice bit of hardware. Unfortunate bit of helicopter parenting. :(

  • Zachary says:

    The fastest way to stop that common fraud of sending it home with a sibling is to implant it…….lol

  • Mick says:

    He should call this the Life Ruiner 5000 and market it to pathologically smothering parents everywhere.

  • anon says:

    This would be a good solution only after problems were discovered.

  • Kenny M says:

    Not really helicopter parenting, its not like the rfids have a GPS module and wifi that transmit there location all the time, its more like calling the kids to make sure they are at the location they said they would be, he could implament this with a door lock so even if the kids had a sibling clock in for em, then they might not be able to get into the house.

  • Jeremy says:

    This is a cool build, so props to the designer. I would like to add that it would be infinitely simpler to just write some code to snap their picture with a webcam and have it encrypted with a date+time stamp. The parents can just look at the snapped images to see their kid and the time it was snapped. It would solve the problem of someone else punching in or the photo being taken elsewhere (you would probably notice if the surrounding image is now the back of a car rather than your living room).

  • Stevetronics says:

    Or, you could just trust your kids..

  • John says:

    Helicopter parenting would be following your kid home from school and telling them how to do their homework. It eventually prevents kids from learning crucial decision making skills.

    This is more just a “come home right after school if you choose to, but I’ll know what you choose.” tool.

  • John says:

    @Jermey

    I was thinking the same thing. Just have a camera at the front door for “security” and it also happens to make not of when the kids get home.

  • curt says:

    Cool, but what month is 16?

  • loans says:

    This isn’t an undue level of concern, in my opinion. If a child tells you he’s going to be home at 4pm, then if he’s not (and hasn’t called [because all kids have cell phones now... i see eight year olds rollin down the road on their bike texting] to explain/ask permission) then it’s a valid cause for parental concern.

  • Nomad says:

    Controlling parents of the world unite! -.-

    nice piece of hardware, but i totally do not approve of its purpose.

  • Jorge says:

    Uhhmm.. cool… I would add a high-voltage discharge mat for kids not coming back home at proper time. They will receive what they deserve!

    (Just kidding :P)

  • Nomad says:

    @Jorge: yeah…that’s where it all starts…at first it’s always “just kidding”

  • I think the same… Control issues…

    Lucky for him it isn’t with me he’s trying that out… I would just split it into pieces while he was away and reprogram it / change the circuit so I had some way of cheating it…

    Fuck parental control!
    (says the guy who is logging all times when his parents is accessing his room…. XD – Child control is okay…)

  • Piku says:

    Or you could simply phone your house phone at a random time just after 4pm to see if they’re in.

    A alternate idea is to trust your children, and if you don’t, then don’t leave them unsupervised until you do…

    … Combined with a sound telling off and withdrawal of Internet and mobile phone privileges if they do it wrong.

  • Dusty says:

    Big Brother is watching.

  • SpiffWilkie says:

    Sounds like a lot of commentors don’t have children.

  • Mike Szczys says:

    @curt: I think that’s day/month/year instead of month/day/year.

  • Lemonmaster0 says:

    @SpiffWilkie

    Or that they’ve raised their kids to be trustworthy.

  • Nomad says:

    @SpiffWilkie: You either can get your kids to come back home at a specified time/call you when they’re late or you can’t. If you can’t, then you just simply fail at parenting. Those kids will never learn responsibility…just routine (wake up, stamp out and go to school, come back and stamp in, go sleep, repeat)

  • zool says:

    “hey can you come over to my house?”
    “yeah but we have to go over to my house first, i’ll punch in, then we can go”

  • Loren says:

    Or at least till the kids figure out how to hack it!!!

  • Itwork4me says:

    Next he’s gonna use the clock to find out his daughters menstrual cycle. This is too controlling. I guess it’s a hack for horrible parenting and child neglect.

    • Itwork4me says:

      Even worse he immortalized his lack of trust in his kids on the Internet so they can hold it against him in the future. What a fucking retard. I hope in the future your kids look this up and say ‘daddy you’re such a ass!’ after they read all these comments. Then they’ll say that daddy should’ve used his ingenuity to get a better job to live in a better city to work at home so he could watch his animals.

  • sarsface says:

    Can you fire your kids if they’re late too many times?

  • Mr.Non-Descript says:

    A lot of parents are split up and/or work multiple jobs (especially in this economy). I can see this being implemented if it were to SMS when a kid gets home (to make sure they weren’t abducted) but not for checking up on their kid’s actual behavior (I was a “good kid” only as i was never caught o O ). Having it text when a kids gets home would at least give a peace of mind if I were in such a situation to need it!

    Being a parent, I raised my kids to be trustworthy (as I would define it anyways) – but it’s the low-life element that I don’t trust… two reported abduction attempts in my medium-sized town in the last year. Trust me, I know some negative effect of trying to be Big Brother to kids – and there’s a fine line between protecting and smothering!

  • error404 says:

    @curt: This is why yyyy-mm-dd is the only sensible date format.

  • Jeremy says:

    @Piku
    What’s a house phone? :)

  • Pikachu says:

    Or you could raise your kids so that you can trust them so you wouldn’t need to stalk every moment of their existence which will just make them work harder at finding a way to do something bad without you knowing.

  • Hirudinea says:

    I like this, if the desire to circumvent this thing dosn’t teach the kids to hack than nothing will, what smart parents!

  • Phlip says:

    Another option is to use bluetooth to determine whether or not the kids’ mobile phones are in the house. Most kids wouldn’t leave the house without their phone. You would even need to tell them how it works…

  • truthspew says:

    If my parent ever did anything like this to me when I was a kid I’d have taken a hammer to the unit. Try recovering that!

  • Quan-Time says:

    Awesome concept in punishing your kids. Bad parenting 101 right there people.
    This would have to be the BEST way possible to turn your kids into future sociopaths and ready for prison life.

  • opihimom says:

    Neat system.

    SpiffWilkie, I agree, there seem to be a few parent-less posters. From my POV, it’s the child that needs to build the parents trust, more than the reverse. The clock-in doesn’t seem very over the top to me. If the kids can manage to check in reliably, then it tells me the kid can be given more slack.

    I’m with Jeremy that a webcam with motion and/or door detection seems a lot simpler.

    I utilized a h/w keyboard logger during the first couple of years of the kids on-line life, and a logging gps for the first few months of solo driving. No, didn’t tell them, and as far as I know, they didn’t find out. If they had, that’d have been a bummer, but having them float out the door with nothing but the prayer that our parenting did the trick wasn’t my preferred option.

  • Daley says:

    I skimmed through part of the article more for the technological stuff than the intended use (I absolutely agree with most of the comments above). I found something interesting in the part where the guy explains (paraphrased) that by the time he was finished, the original requester had moved away – negating its necessity.

  • SirBlade says:

    Looks fragile…

  • Bad Parenting 102:

    For the next project in this series, a DIY ankle monitor with GPS location tracking, using a cellphone with GPS tracking, built into an ankle strap with integrated tamper alarm, so that parents won’t have to worry about their teenage daughters getting knocked up.

    Oh, wait, that might hurt a child’s self-esteem. Never mind… ;-)

  • Greycode says:

    There was a saying once, “Trust, but verify.” All that is being done here is making sure that they were home when they were supposed to be home.

    Trusting a teenager is dangerous, I was a “good” teenager and I still went to keg parties. No one would have suspected me to have done anything out of line. There is not a teenager yet that I would trust as far as I could throw myself.

    If you don’t like this, don’t use it, your teenagers are probably real trustworthy. Some of you are teenagers, and I bet you are momma’s lil’ angel. You are so trustworthy that I am thinking about a neck bracelet to compliment this system.

    The camera addition though, that is what is needed. A picture with the log in would prevent siblings from vouching for them. Taking the RFID antennae and either using doormats or door frames as the log in points. Also fixing the tag to the cell phones is a great idea. I don’t know a teen in existence that would leave home without it.

  • anon says:

    nice hack, bad parenting.

  • reasonable says:

    @Greycode… But still… you are probably glad you got to go to those keg parties… would you have been happier if parents + technology prevented you from *gasp* being at a party?

  • J Harton says:

    Anyone who wants or “needs” this is a control freak. Maybe 11-13 is reasonable if you want, but teenager is a much wider range. If you don’t trust your kids don’t expect them to trust you and don’t be surprised when they vandalize your system because it’s privacy invasive or a pain.

  • wally says:

    It intrigues me the impact that technology appears to have had on parenting in my (fairly short) time as an adult.

    I’m young enough to remember being a kid, I’m at the age where I might start giving serious thought to starting a family myself (as I’m all grown up and married now), perhaps part the difference is living in the UK.

    I remember clearly my parents just trusting me. If I blew that trust, shame on me. If I blew it twice, shame on them. There was always an amount of grace, an “OK, I trust you’ve learnt your lesson”, if it happened again, they’d be there waiting.

    Personally, I learnt what was acceptable and unacceptable behaviour pretty quickly. I don’t think that has a lot to do with my own intelligence level or anything. I accept some people have specific difficulties which this kind of system would be well suited to, but (the point ‘ve been working around to) I can’t help but observe that these systems appear to become more and more popular all the time.

    In the UK, it seems to have always been phone calls. Then mobiles became common place, and it’s texts / mobile calls. Now it’s facebook messages. Whatever it takes to keep tabs on people. Even when they’re 20 or more years old.

    It saddens me. Why? Because for the people I know, they’ve grown to either be unable to make their own decisions, or to resent their parenting.

    I think this is good hack, it’s interesting, and it’s got uses. Not sure I agree with what it’s being used for here.

  • darkore says:

    Nice, but definitely suboptimal. It would be so much more efficient to chain them to the floor with steel cables. That way you’d be sure that they aren’t going anywhere.

  • wally says:

    Meant to add, and forgot:

    Of course my opinion might move if I ever do become a parent. Maybe one day I will trip across a long ago archived copy of this thread on the “waybackmachine” and think “yeah, I was pretty ignorant back then”!

    /wally

  • Anders says:

    Talk about worst parenting in history. They sucked at raising their kids so much they need extreme measures like this? Some people should not be allowed to have children.

  • smoker_dave says:

    “Keep your kids in line with a time clock”

    As opposed to some other kind of clock?

  • smoker_dave says:

    BTW if the kids are as smart as their parents, they could find the RFID spoofer on hack-a-day from a few weeks ago and program it to present both their ID’s at set intervals.

  • strider_mt2k says:

    Couldn’t you simply beat your kids senseless with a regular mechanical clock until they behave?

    Old tricks are the best tricks I always say.

  • strider_mt2k says:

    It worked for Bing Crosby is what I’m saying…

  • darkore says:

    @strider_mt2k: thanks, that made my day :)

  • fartface says:

    Um… yeah… have the kids punch a timeclock. That will work. Johnny will always punch in and out. Really!

    A better solution, install security cameras and a security DVR.

  • Ben R says:

    @wally You’ve got the point, right on the money — and I am a parent. On this side of the pond there’s a movement to try and get back to the sort parenting we recall from just a couple of decades ago (Google “free range kids”) but it’s a slow uphill battle, fighting against shock journalism and a general fear of our own shadows that it has caused.

  • octel says:

    In the USA, people under 18 years of age are legally the property of their parents. In a word, chattel.

    There’s a low-level hack for this: cattle runs. Just build some barriers to direct your human property to and from their destination. High school administrators could pull double-duty as child herders.

    If you’re going to take to tacitly admit that your kids deserve as much freedom as livestock, why not just drop the pretenses and take things to their logical conclusion?

  • Sendaii says:

    What a waste of a perfectly good Arduino.

  • FractalBrain says:

    This is wonderful! I would totally make this. Of course no one but I would use it. In fact, the kids (when I have them) would probably roll their eye, and my wife would pat me on the back. But thats not really the point. It would be fun…I’ll bet this was. However, to do it right…

    Octel: What about cattle prods? Cattle runs would obviously make things more efficient, but thats a bit like making beautiful straight road and then telling everyone to drive at walking pace. Why not take advantage of the added efficiency by speeding the child units along with cattle prods. That way this time tracker could be used not for silly things like trust, but as a optimization tool to optimize child unit speed.

    …but then of course, being a barrier, the cattle run could easily be destroyed by zombies.

  • Greycode says:

    Personally, I am under the impression that our teachers are essentially cattle herders, teaching however would put them on double duty.

    @ reasonable, I am glad I got to go to them, but I saw people who did it all the time, and they grew up to be unwashed heathens. And now, they are growing up little unwashed heathens that will become unwashed hordes.

    This is something that simply does what it is supposed to do. Make sure that a kid is following the rules of where to be, and when to be there. Nothing evil about it, and nothing extreme either. I would worry more about the children whose parents simply relied on trust, which I can assure you is a rare commodity in teenagers of any day and age. I do not fault the teenager, that is exactly what they are supposed to be doing. They need to learn limitations, and this is simply showing them where those limitations are.

  • octel says:

    @FractalBrain
    cattle prods add unnecessary aggression and harm potential to the mix. we can lure our human cattle err.. _precious offspring_ to any place at all via carefully-planned bait such as Apple products or the latest Bieber album

    an alternative would be to ferry all children to and from their destinations using large unbreakable plexiglass tubes like the kind they have at banks for transporting documents. each child would be individually packaged and guaranteed aseptic

    an even better high-tech solution would be to put children in maturation chambers where they will absorb cultural norms and factual information starting at birth without the risk of interaction or contamination from harmful ideas/practices
    basically, something like a cross between the matrix/borg/zerg

    americans hold property rights in high regard, which is why you often hear the cry of “think of the children!!”

  • Phk says:

    Bad parenting 101… those are going to be some messed up kids

  • Hamish says:

    Yeah…you could create a complex and controlling environment, watch your children in everything they do, build up a barrier of distrust and distance yourself from them, rendering them totally uncapable in the adult world…

    Or you could build trust and teach them these new fangled ‘Moral Values’, like honesty, compassion, responsibility, and actually being a part of your children’s lives, not simply controlling them.

  • N0LKK says:

    I’m not so sure how this would mess up kids anymore than having Mom, or dad in the home after they arrive some school. Generations survived with mom being home to note. Many more generations survived have both mom, and dad around the farm or the family shop for most of the day being “smothering”. This is only a tool for newer realities, like all tools it can be use poorly or used well. My guess is those commenting against this are the parents of the little turds whose crap we have to endure, because the parents don’t do the most rudimentary monitoring of their angels.
