Hardware Hackers Create a Cheaper Bedazzler

ptorrone writes "Hardware hacker extraordinaires Ladyada (Adafruit Industries) and Phil Torrone (of MAKE magazine) have just published an open source 'Homeland Security' project, a non-lethal LED-Based Incapacitator: THE BEDAZZLER. After attending a conference where the $1 million 'sea-sick flashlight' (THE DAZZLER) was demoed by Homeland Security, the duo decided to created an under-$250 version, and just released the source code, schematics and PCB files. The team also released a 5 minute video describing the 'official version' as well as how they created the 'open source hardware' version."

      From what Ladyada has posted here and elsewhere, I'm convinced that it's as effective as the Homeland Security version. Which is, not very.

      The basic problem with nonlethal weapons is that they assume there's a range in which a weapon is more than annoying, but less than dangerous:
      |====annoying===| sweet spot |====dangerous====|

      But because people vary in their responses, it looks more like this:
      |====annoying===|

      Sorry for writing an essay, but you basically are demonstratively wrong in 3 of the 4 assertions you just made. Mobile phones are essentially innocuous and to liken the two raises questions about your understanding unless you can clarify. You're right that the mosquito isn't as loud as a rock concert (assuming you're very close to the speaker), although you're wrong about the jumbo jet part. I won't bother with the "repetitive" bit beyond stating that it's more just a loud noise.

      It's 108 decibels, so it's actually over six times louder than a jet taking off 305 meters away (100 decibels). 100 decibels causes "serious hearing damage" after 8 hours, so, if damage is a linear function of power (it's not, this underestimates damage) then it causes that same "serious hearing damage" after only 75 minutes.

      The reason this isn't obvious is because teenagers can hear it and get away. Infants can't, but the parents probably won't associate their child's hearing impairment to something they didn't even know was there. Most adults have lost most of the pili which would receive the highest level of damage, but it wouldn't surprise me if there's some damage to other pili with such an intense sound.

      But hey, I'm just a random person on the internet with easily verifiable conversions of decibles to watts and simplified explainations of noise related hearing loss. You'd be wise to not take what I say at face value. So, take note that neither the UK nor Germany (check Wikipedia for links) were willing to define the safe exposure limits to these devices. It's known that it affects quite a bit more than high frequency hearing (e.g. vestibular system). Part of the problem likely lies in the fact that hearing damage is generally assessed in the lower frequencies that human voices use, so other types of damage are less conventional to assess.

      Non-ionizing EM radiation and loud sound waves are quite different. It's unlikely (albeit possible given that there are biologically organized magnetite crystals in our brains) that we can even detect the former, and diamagnetic levitation of frogs and spiders seems to have no ill effects (not to mention MRI). The latter causes people to naturally want to escape it. If that weren't the case the device wouldn't be effective. How can you possibly compare the two as far as safety is concerned???

      You may be right in that the mosquito isn't deadly but is still effective. OTOH, it's not a weapon and it can be ignored, thus making it useless for dazzler-type purposes. If you increase the volume it's no longer "safe" nor specific for younger folk (anyone can hear high frequency sound, just not at the same volume levels). And I'd argue that the device has too many false positives (i.e. older people that hear it or just get headaches) for it to even be effective at its intended purpose.

      The maximum safe exposure levels of light (as a function of wavelength) is well known and documented, e.g. by OSHA or other occupational standards bodies. Incurring temporary blindness isn't necessarily dangerous and is sometimes used in vision science studies. The procedure is called "bleaching" as it relates to a temporary chemical depletion of the rhodopsin pigment. Its not permanent blindness so I don't think the Geneva ban would apply.

      The choice of green light in the original dazzler is smart because it saves power (green being close to the peak wavelength sensitivity for the human retina), and its also a relatively safe color to look at. Blue is an order of magnitude or so more dangerous. Red is safer but not as visible so the power requirements would be much greater.

      The people who cooked up this $250 hack don't seem to be aware of that fact that light damage is wavelength dependent and have made theirs with full RGB color... so yeah, this is why we give money to the pros.

    I'd call them "dirty cops". Sadly there are far too many, but not all cops are.

    "Dirty" cops are a subset of the problem. They are the corrupt ones who misuse their position as law enforcement for their own gains or play along when officials above them do the same. It is a problem. I agree that not all cops are dirty.

    There are also cops who are not corrupt but still fail to "protect and serve". Some are un-necessarily brutal. This ranges from beating up suspects who offer no resistance (until it became clear they would be beaten up), perhaps for a minor technical infraction. In some cases, people who have done nothing wrong at all (however minor) end up on the wrong side of a beat down.

    Others don't cross that line but have obviously forgotten that their job is to "protect and serve" not to be treated with the sort of deference that used to be reserved for Chinese emperors. They are the ones who seem to take personal offense if they can't find something you did wrong so they can write you a ticket. They "thought they saw a beer" and when proven wrong, keep looking for something else. They ooze the attitude that you serve them and they will GET you one way or another. If there's actually nothing at all, even a technicality, they can write you up on, they will "let you off with a verbal warning" rather than just apologize for the inconvenience. Yes, I know it's awkward to accuse someone and then find that your wrong. That's WHY an apology is in order. Your best hope is that the other person will accept it graciously. It would be a lot less awkward for them if they hadn't subvocally appended "you dirty little sack of shit" to everything they said to you before being proven wrong.

    Next on the list we have those who somehow enable the above categories. They treat what would otherwise be considered a brutal assault worth not less than a year in prison as "some kind of mis-understanding" (yeah, the mother of two didn't understand that she might get yanked out of the car by her hair and kicked in the ribs if she pulled over like the law says she must for a minor traffic stop) and do nothing significant about it. They missed the part of kindergarten where we learned about saying you're sorry. They might reluctantly admit that some officer's actions were out of line but you can actually tell from the attitude they project that in their minds they're sure the victim was guilty of something and somehow managed to put one over on the bleeding hearts.

    While only one category above is "dirty cops", all are unambiguously "pigs". They are the ones that make cops unwelcome in a neighborhood. They are NOT by any means 100% of the police force, but the odds that any particular cop approaching you is one of those are high enough to tempt even the most law abiding citizen attempt to avoid the encounter. They make parents think twice before advising their children to go to a cop if there's a problem. Some of them are decent enough when they're NOT on duty (to the point that friends and family would be shocked to see their on duty behaviour).

    The remainder are "police officers". They are what 100% of the police force needs to be made up of. They are, of course, imperfect human beings like the rest of us but they acknowledge that and try to get it right anyway (just like most of us). Because they can acknowledge that they are imperfect human beings, they are able to understand that the rest of us are as well and act accordingly. They can even understand the concept of "no harm, no foul" in spite of laws written in black and white (by imperfect human beings).

    The big problem they face is that it doesn't take many "pigs" amongst the "police officers" to make it in an honest citizen's best interest to assume the worst. It takes even fewer to be a problem for honest citizens legally doing things that are politically inconvenient (like protesting). When the problems are higher up the chain of command there may be little or nothing a proper "police officer" can do about it.
