Science of Irrational Behavior

A lovely book review from The New Yorker. The book sounds like fun:In "Predictably Irrational: The Hidden Forces That Shape Our Decisions" (Harper; $25.95), Dan Ariely, a professor at M.I.T., offers a taxonomy of financial folly. His approach is empirical rather than historical or theoretical. In pursuit of his research, Ariely has served beer laced with vinegar, left plates full of dollar bills in dorm refrigerators, and asked undergraduates to fill out surveys while masturbating. He claims that his experiments, and others like them, reveal the underlying logic to our illogic. "Our irrational behaviors are neither random nor senseless -- they are systematic," he writes. "We all make the same types of mistakes over and over." So attached are we to certain kinds of errors, he contends, that we are incapable even of recognizing them as errors. Offered FREE shipping, we take it, even when it costs us.Another review from The NYTimes with an entirely different set of examples. This is definitely starting to sound like a fun read.

Strange Canine Behavior? Answered

My dog (you can see her here and on my profile) is exhibiting strange behavior. She is a little under two years old, and she is a pointer mix. We also think that she has a little bit of boxer or pitbull. Whenever she eats her food, she will walk into the kitchen to get a mouthfull, then she wil walk across the house and chew it up and swallow. She will either do this with some mouthfulls or nearly all of them. Is this normal behavior? Shes not a normal dog when it comes to how she behaves (shes been on my roof twice,) but I have never seen another dog do this before. Please help.  thanks, freeza36

Instructables app behavior (Bug?)

I've been using the Ibles app on an Android (V 4.3) phone for a month or two. There's a lot to like about the app experience. For instance, the app makes it super easy to follow other users who are following your account... Super easy to click "follow" on many accounts in one session. I'm not really a social networking person, by choice, so I never paid much attention to following. Never cared about the number of followers--or hits, for that matter. I'm sure this is a breach of social networking etiquette. Guilty.  So-- it's a pain to "mass follow" other users in the browser interface (yeah, wouldn't be problem if I'd kept current with following)--go to you:subscribers, click on the account, select follow, move backwards to the you:subscribers page, repeat ad nauseam, with all the load times associated. On the app--load the followers page, then click, click, click on the icon next to each account. Pie easy. But there are some odd app behaviors: One: the app Followers section doesn't sync with the normal online interface. I.E., more followers in the browser online than on the app. Two: the last "follower" in the list doesn't display correctly. Shows as "not followed," when clicking on the user's account shows that I am indeed a follower of that account. Maybe there's a sync lag that would explain this...if so, it last several days.

NPN BJT strange behavior? Answered

My linear power supply design has been using a PNP MJE2955 pass transistor wired to a 2N4401 as a complementary darlington configuration, but this was not an inherently stable design, and would oscillate when adding output smoothing capacitors, particularly MLCC types (with very low ESR). So I decided to try the far more common darlington arrangement, although I am not fond of the higher voltage drop. However the output was oscillating at approximately 3KHz with 1uF output capacitance, with NO input to darlington. I removed the 2N4401 so all I had left was just a 2N3055 transistor with the emitter connected to the output and the collector connected to a 20V supply. The output was ringing like crazy. The oscillation frequency could be changed by adding/removing output capacitance. Why is this happening? How should I go about stopping this oscillation? I originally had a 4.7k resistive load on the output but it did not significantly affect the output oscillation.

Samsung monitor strange behavior?

I have a samsung S27A350H 27" 1080p TN Monitor which for a long time has worked just fine, permanently plugged into the HDMI of my old desktop. However I now have a better laptop which replaced the desktop, but I find that the monitor occasionally will not display a picture when plugged into my computer. I have nvidia display output settings set to output 1920*1080, 60p, with full (not limited) 8 bit colorspace. I do not know the settings of the HDMI output. I find that if I close my laptop lid, W10 goes into either a sleep or hibernate mode, and stops providing a signal to the monitor. If I wake windows again, the monitor will not display anything. Windows appears to detect the monitor fine and extend my desktop as it should when this monitor is detected. However the monitor appears to bounce between looking for a "digital" and "analog" source (HDMI and VGA respectively) Unplugging and replugging the HDMI connector has no effect. Windows detects the monitor fine, monitor does not. Changing the output resolution, frame rate, and colorspace does not appear to change this behavior. The monitor requires a deep power-cycle. Powering it off for several minutes (supposedly to allow charge to bleed away from internal capacitors.) usually (but not always) temporarily fixes the issue. The length of time needing to be unplugged seems to vary between seconds and days. When the monitor enters this nonfunctional state, no HDMI signal is detected. (tested by replacing my computer HDMI source with a raspberry pi. I did not go so far as to adjust the HDMI output settings of the Pi by editing the config file, but the settings were previously changed to optimize the picture quality with this particular monitor in the past anyway. This monitor appears to have a simalar issue with the VGA adaptor. However fixing it is generally a matter of unplugging the VGA and plugging it back in again, or opening up the display settings on W10. Online sources appear to suggest that a firmware bug in the monitor is the culprit, and the only way to fix the monitor is to connect the monitor via VGA and use the samsung firmware tool for this monitor to update / reflash the firmware,the explanation being that a bug in the firmware causes it to overwrite parts of itself, corrupting itself as a result. However the executable provided by Samsung immediately crashes after a successful installation of it and the driver when clicking to reflash the firmware in the software. I found no information regarding the error message that appears. (note my current and only laptop does not have a VGA output. Not sure if this is the reason it crashes, the error message does not give much detail. ---- When I first received this (supposedly broken) monitor from my uncle for free, I found that it was under the warranty period and the problem at the time was that it would not display VGA or HDMI signals. Samsung offered to repair the monitor under it's warranty, and since, it has worked fine, being connected to my main computer permanently.  I suspect the problem then is the same one manifesting now.

Scholarship contest idea: evolving navigation behaviors

I am interested in the evolution of complex navigation strategies. As a first step, I am using the Avida digital evolution platform (http://devolab.cse.msu.edu/software/) to evolve behavior that corresponds to chemotaxis in bacteria such as E. coli. Although they are very simple organisms, bacteria like E. coli have served as model organisms for studying the molecular biology of behavior, and have been studied extensively. Such simple organisms provide a good starting point for evolving simple behaviors that may eventually serve as a platform for the emergence of more complex behavior. Chemotaxis is a simple orientation behavior, performed by many different organisms, involving moving either toward (positive chemotaxis) or away from (negative chemotaxis) the source of some particular chemical signal, by sensing and responding to the chemical gradient in the local environment.The project I am proposing for the contest would port the software evolved in Avida onto the Create robot, and demonstrate the virtually evolved capability in the real-world environment. Since performing chemotaxis in air would involve dealing with turbulent dispersal of the chemical signal, I propose to use phototaxis or thermotaxis -- orientation to a light or heat source, respectively -- as an analog to chemotaxis. This will greatly simplify the experiments, since the problem will then be one of diffusion rather than turbulence. The robot will follow the light or heat gradient, tracking toward the source.Several things will be necessary to accomplish this. In software, the virtual CPU instructions of Avida will have to be translated to the robot. Because of the runtimes for Avida experiments, the evolution would be done offline; the robot would run the program that is the result of evolution. Hardware implementation would include the addition of photosensors or infared sensors, to allow the robot to sense the light or heat gradient. Care will need to be taken, both in the digital evolution and in the robot experiments, to ensure that the real environment is similar enough to the digital environment during evolution, so that the evolved program can function in the real world environment.Although tactic behavior has been implemented in robots in the past, to my knowledge it has never been done using digital evolution. An evolutionary approach has several advantages: 1) the finished program is discovered through evolution, instead of hand-coded step-by-step; 2) evolution may find novel ways of solving the problem that a programmer might not think of; 3) because of (1) and (2), the evolved solution may be more robust and adaptive than a top-down, engineered solution.

Crazy behavior when clicking from email

I'm surprised that no one else has reported this, because it's pretty severe. Whenever I click a link from your email newsletter, the page never stops reloading. Everything works fine when I've called it up directly from instructables.com, but when I click a link or image from the newsletter, everything bounces around and it never stops. Clicking the stop ("X") in Chrome doesn't help, because then the page is only partially loaded and none of the javascript works. I'm on Chrome, up to date at current release, Windows XP at final release; email is gmail. I don't think I can provide a screen dump that captures the, um, dynamic nature of the problem--like I said, the page just never quits jumping. The first time I noticed it was within the last few weeks, not sure exactly, but at first I thought it was a fluke. Since that time, it has happened every time.

Sorry for the slow and annoyingly bad behavior of Instructables

We’ve been going a lot of work under the hood, and some of it just hasn’t come out quite right. So, I’d like to apologize to everyone for the site’s unresponsiveness and give an extra, sugar-on-top apology to anyone who lost a step or a comment. Not that it’s any consolation, but I lost both steps of an Instructable and a few comments over the weekend. When stuff doesn’t take, I usually just hit the back button on my browser and can copy out my text. For some reason that didn’t work, so if it happened to you too: I know how you feel. We’re working super hard to correct the problem, making progress, and I’ll let you know when it’s under control. There are always new features in the works, and I’ve been taking your comments in the forums to heart. If you have any questions, comments, or concerns, please always feel free to drop me a private message or email. Thanks for sharing your projects. I continue to be amazed by them. Eric

Attempting to create tiny, wearable, covert, simple button click counter for behavioral mod

Hi all, I've been searching both this forum and the internet in general and strangely have not come across what I'm looking to do even though to me it seems very simple. Here are the specifications/requirements of the device that I am trying to create: -extremely tiny form factor (ideally a ring sized device but I'll settle for a thin bracelet) -unobtrusive/inconspicuous (I guess a thin bracelet that could hide under a sleeve might be best) -battery powered/untethered (This is essential. The device would be useless if depended on a connection to a computer or wall socket) -battery life must last a full day -data logged is just a simple time/day stamp that would indicate when a button was clicked by the wearer      (wearer would manually click the button during the day when certain thoughts came up for him/her)       This requirement indicates that the micro controller chosen would need a clock built in and        some kind of storage - be able to upload the data to a computer I did my preliminary research considering these requirements and I came up with the following electronic components that might work: - teensy 3 (has real time clock and 2K EEPROM which should be plenty of memory for storing date stamps) - ulog (1MB of usable space across 3 analog channels, couldn't find anything about a built in clock) - Pro Micro - 3.3V/8MHz (not sure about built in real clock  but storage is 32K flash space) - OpenLog (wasn't clear about how much built in storage and didn't see any build in real time clock) These are the best I could find. If anyone has better suggestions please let me know? My idea is to connect a Mini Push Button Switch to one of the digital inputs on one these micro controllers/data loggers and write a simple sketch that records the time the button was pushed in a MMDDYYhhmm format (10 bytes per click). To power any of these micro controllers/data loggers I was planning to use a Coin Cell Battery - 12mm. I was going to sew the micro controllers/data loggers on one side of a thin piece of material that would serve as a bracelet and sew the battery on the other side. Although I'm not sure how to fix the battery to the cloth and how to connect it to the micro controllers/data loggers. I'm guessing I could find some kind of battery holder for the 12mm cell battery? Other Questions about my assumptions: Will I have enough storage left over on the flash space or EEPROM to store the data click after the sketch code has been loaded in? Will a watch battery provide enough energy to run this device all day? Is the Coin Cell Battery - 12mm the correct external power source for this project? I encourage any feed back, criticism, comments, help of any kind to move me along with this preparation so that I can move forward and purchase the parts I need. Thanks! Michael

lead acid Q's? Answered

So me and papa have been working on farm equipment and an electric golf cart (and I had issues with my jeep cranking over, with a presumably bad battery), but my lack of knowledge of these batteries used in the machines is starting to get to me. Differentiating normal behavior from behavior indicating a bad battery or other problems is not really something I can do right now. What I know: Topped off voltage: 15 (ish) volts ( details?) Dead flat voltage: 10 volts Cold cranking amps: indication of maximum current a battery can deliver in the cold (details ?) Reserve minutes: equivalent to "AH" rating times conversion factor lead acids can take a beating and survive without a, less say, "exciting" failure mode What I don't know: How am I supposed to know what I don't know???? ;) What is a typical topped off voltage for a battery? Does the voltage sag from say 16V when charger is removed? What characteristics change as they age? I would guess increased leakage current/resistance, reduced current capability and reduced capacity (?) would you lose a bit of capacity real quick after cycling a deep cycle marine battery a few times? I know lithium ions do, every new phone I ever had has lost at least 10% of it's capacity in a few short months as it got "broken in." What about maximum charging current? Does ripple current matter?

TSA Security and why George Orwell is the New Nostradamas

This is basically ripped from Digg, but I'd much rather open discussion here rather than over on Digg as Digg isn't a discussion, just a horde of comments...Travelers at Sea-Tac and dozens of other major airports across America are being scrutinized by teams of TSA behavior-detection officers specially trained to discern the subtlest suspicious behaviors...Such people are referred for secondary screening, which can include a pat-down search and an X-ray exam. The microfacial expressions, he said, are the same across many cultures. ...a central task is to recognize microfacial expressions....ArticlePerhaps you've read Orwell's 1984 - if you haven't, do so.He did not know how long she had been looking at him, but perhaps for as much as five minutes, and it was possible that his features had not been perfectly under control. It was terribly dangerous to let your thoughts wander when you were in any public place or within range of a telescreen. The smallest thing could give you away. A nervous tic, an unconscious look of anxiety, a habit of muttering to yourself—anything that carried with it the suggestion of abnormality, of having something to hide. In any case, to wear an improper expression on your face (to look incredulous when a victory was announced, for example) was itself a punishable offence. There was even a word for it in Newspeak: facecrime, it was called.Digg Linked HereAgain a link to the Surveillance map - in which we (US) have joined the UK, Russia and China as an Endemic Surveillance society...LinkHow do you feel about your privacy?I say this as I personally have almost nothing but contempt for the TSA....

CrowCam - Video camera taped to a crow

I was reading an article on attaching cameras to wildlife (Clipped to a Shark's Fin, Collared to a Bear or Attached to a Crow's Tail, Wildlife Cameras Come of Age in BioPhotonics) that mentioned cameras light enough to adhere to birds, specifically crows.Check out this video of a crow flying, foraging, and using tools all from a tailfeather-perspective:http://users.ox.ac.uk/~kgroup/tools/movies/crowcamS3.mov(Let me know if you find an embedded version)The work was done by a group at the University of Oxford and published in Science late last year:Video Cameras on Wild BirdsThere's also a nice NPR piece on the subject here:Crow Cam Captures Creative Behavior in the WildI find crows to be one of the most interesting urban animals, and I love how this video lets me voyeuristically peer in on their antics. Which animals would you watch?

Agnostics, Atheists, Skeptics: Help us Christians out!

Ok non-believers, Here's your chance! I am genuinely interested in what BEHAVIORS among Christians truly offend or irritate you. I'm not really interested in biblical inspiration, theology, and belief systems here. "Free-will/Predestination", "Creation/Evolution", and "biblical inspiration/made-up-stories" have been done to death, and I don't really want to discuss those issues in this topic. I mostly want to know what attitudes and actions on the part of Christians, really rub you the wrong way. I will not argue: Biblical accuracy, the existence (or not) of God, or church history here. I also won't dispute your individual experiences with "church people". To be honest, I just want to know how to be a better person. So keep the comments: nice, to the point, and constructive. I will give all genuine criticisms a fair shake.

Negative impedance output from 5V phone charger!?!?!?! ?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!? Answered

I acquired a handly little USB multimeter thing that goes in-line with a phone charger to measure voltage, current, resistance (?), and voltage on the data rails as well. I was able to go through my phone and car chargers and dispose of the crappy ones that would not charge at a fast rate. However, I noticed that my samsung (OEM) chargers appear to somehow compensate for the resistance of the USB cable! The charger would output 5.1V under no load but that would rise to 5.3V under load! It does this for any device, not just my samsung phone. The voltage rise seems to be proportional to the current. My guess is that the supply has some positive feedback within a certain current range and voltage range that allows it to roughly compensate for the drop in a long USB cable. How would such behavior be implemented in a feedback loop in a way that avoids parasitic oscillation. It seems that it would require positive feedback, or some way to modify the voltage reference voltage in proportion to output current.. I am intrigued! Any insights?

How to make Arduino triggered still camera?

I'm looking for a simple way to make a camera using Arduino with the following properties and behavior: -when a certain signal from a sensor or switch gets to the Arduino it takes a single picture and sends it to some kind of memory, preferably a large one that can hold a lot but is small in form factor like an SD card or USB stick. -the camera is always on and waiting for input, allowing the image to trigger immediately upon sensor trigger -the whole thing would work with a fairly small form factor Arduino board, shield, and camera module -obviously camera quality is important, something that would give a reasonably clear image within a fifteen foot distance and in a variety of lighting conditions without a long time taken to focus would be ideal. It seems like most guides I've seen are for video cameras with a ton of options or other inputs. I just want a stupid simple camera that only returns one picture for one input, with an on off switch. Looking for product suggestions or pointers to guides to do this. I'm pretty inexperienced with Arduino. thanks so much!

$99 genetic testing, one day only!

This is cool:  23andme is having a one-day sale on their Complete Edition kits in honor of "DNA Day" for $99, or 80% off the standard price of $499.   The price is ONLY good on April 23, 2010. $99 to spit and a tube and get info on 148 diseases adn conditions, plus some info on your ancestors' migration patterns?  This is the next best thing to DIY genetics - totally sweet!  A bunch of us at Instructables have already signed up*. What do you think about the idea of genetic testing:  awesome, scary, or somewhere in between?  Are you interested in getting tested?  How much is this kind of informatino worth, and would you try it if it were free?  Are there things about your genes you wouldn't want to know, or is more information always good? *I find this sort of thing fascinating, and not just because my undergrad degree is in biology - for me it's about knowing everything I can about my body and how it works.  The more information I have, the more I can modify my behavior, and generally tinker around under the hood - it's an extension of the "if you can't open it, you don't own it" DIY ethos.

My Dilemma

I've been meaning to tell the community this for a while, but I might as well do it now... I have ADHD and Bi-Polar Disorder. My mom and I decided that I should try and get off one of the pills I have been taking for years: the one to combat Bi-Polar Disorder. We realized today that it is better for me to get back on them; I haven't been taking it for two days. I'm not trying to start a sob story, but I'm just saying this to explain my weird behavior. I'm sorry if I've weirded you guys out, but I haven't been thinking straight and I'm kind of going through mood swings. Don't be alarmed, it's nothing too serious, but it is definitely enough to make me seem irritable and strange. I still do stand by the things I said in the 'war' that seems to be going on at Red's instructable about the classic guns; or at least most of them; I may have to go back and make sure I know what I said.  I've probably said some things I may regret, and I'm very sorry. Sorry for all that. :I -DOK

tiq probe - a new kind of electronic debug tool for makers, techs and engineers

Hi! I'm launching a new product on Kickstarter this week that I think will be a great help to makers! It's called tiq and it's a new kind of high-performance tool for debugging electronic circuits, including projects using Arduino, Raspberry Pi, PCI, AVR etc. When you're debugging a project, you're usually looking for unexpected behavior, and you probe around the board to find out what's going on. With conventional test equipment this can require multiple pieces of equipment, hooking each up to your target, which often is in a hard to access place, changing ranges and looking away at the equipment displays. With tiq you can simply probe your circuit and tiq will display detailed logic level, logic pulse and voltage information completely automatically, without range switching or adjustments - and show it all close to the probe tip! Here's a one minute video of tiq in action: http://youtu.be/aNhjCvGdqkA Here's a short overview of tiq's features: http://www.innavatus.com Please let me know if you have any questions about tiq. I will post a link here to the Kickstarter page when it goes live. Cheers - Mark
