  • Using K-type thermocouple to measure human body temperatureMarch 28

    Is there anything I need to he aware of when using K-type thermocouples? I got the idea by touching the probe. I can get a reading when measuring temperature for 30 seconds using a DMM. A commercial electronic thermometer needs around minutes for the

  • Measure human voice for ambient noise level

    Measure human voice for ambient noise levelMay 14

    I need to develop an ambient noise level to measure the loduness in an office. Sometimes during the day people raise their voice more than they should and a lot of confusion is created. So this device should be installed somewhere, like on the table

    What waterproof temperature sensor do I need to measure water temp using an arduino mega?May 14

    I consider myself a complete novice when it comes to electronics. My current project consists of measuring water temperature using an arduino mega. What parts will I need to complete this project? So far I searched sparkfun and arrived at this: http:

  • What is the maximum audio bitrate humans can distinguish? August 31

    Some audio bitrates go as high as 256kbps. But I have listen to very very clear music with 92kbps. I became suspicious that beyond a certain bitrate of x kbps the average human ear cannot tell the difference at all. What is x? Though the question is

  • Applying the copy-swap idiom to humans and employeesMarch 31

    I came across this post which explains the copy and swap idiom. However I could not find this idiom applied to classes that have base classes. Following is my attempt of a copy-swap idiom applied to class constructors and assignment operators. In the

  • Human touch pins on MCU (atmega328p) directly or other components needed?

    Human touch pins on MCU (atmega328p) directly or other components needed?January 3

    I would use atmega328p to read the pulses transferred in human's body. So I wonder if that's good to directly expose the pins of the chip. Or there should be some type of components for protection and noise filtering. e.g. maybe a 1n ceramic cap in s

    Why would my computer all of sudden reset clock, show new boot screen, and run fans loud?October 23

    I bought a new computer one year ago, it's worked fine (Windows 7). A few months ago, it started to not boot unless I removed my USB headphones connected to a USB hub, everything else worked fine. Today I pressed the space bar by mistake while the co

  • 4-20mA Current LoopsFebruary 16

    Why was 4mA and 20mA picked? Was it an arbitrary choice? I don't see this signalling method used much in hobbyist projects, why's that? What are these current signalling loops best for? --------------Solutions------------- 4-20mA loops are used a lot

    My computer started to freeze at irregular times for 3 weeks now. Please note that this question change with each things that i try. (For additional details) What happens My computer freezes, the video stops. (No graphic glitches, it just stops) Soun

  • Isn't all user testing essentially a way of gathering how people think things should work?July 12

    When user testing is performed, users are often presented with a serious of variations of a product and observed to see where they excelled and where they had trouble. People will often click in areas that are not intended to be clicked on, or may tr

  • Soft i2c with Sensirion SHT21 sensors on Arduino MegaApril 4

    I have tried checking with an oscilloscope on the analogue pins when the sensor is plugged in and I don't seem to get anything as I normally would. The hardware i2c channel works just fine on the mega, its the soft ones I am trying to use that don't

    How can we get into the user's mindset?August 13

    As security folk, we tend to over- or under-estimate the capabilities and educatedness of our users, especially in terms of resistance to social engineering attacks. Stereotypically, this is due to us all being basement-dwelling social rejects, but m

  • Touching Person-to-Person

    Touching Person-to-PersonSeptember 26

    Is there any way to detect skin touching or no-touching between two people? Maybe using capacitive sensing or any other methods? It doesn't need recognizing gesture, only yes-or-no-touching. The constraints are: Two people in the classroom. (Each per

  • Any tools/suggestions on how to refute code coverage quality argumentJune 20

    Now I know people could consider this question duplicate or asked many times, in which case I would appreciate a link to relevant questions with answer to my question. I have been recently in disagreement with some folks about code coverage. I have a

    How is current controlled in high power applications?October 31

    When working with electronics, it is quite easy to regulate current with a resistor, potentiometer, switcher, etc. But take a simple high power application such as an electric stove. What method is used to control the current through the burners. The

  • User safety for battery powerd device against misuse of power supplyJuly 10

    I want to design a safety circuit for a battery powered device which measures human body impedance. It is intended to be powered only by an external battery pack (5V) via a USB cable. But I want to make sure that even if device is connected to wrong

  • Creating a cron job and watching its output in real timeJune 6

    When I look at the questions and answers on this forum, it seems like the threshold to ask a question is very high. At least for someone like me, with very little knowledge of Linux. Most of the questions about cron jobs are out of my league, includi

  • How do I use arrays in combination with constructors?January 17

    I'm currently making a depression-simulation program where I created Human objects that have multiple parameters which alter the way the depression will affect them. My issue is that I am able to create singular human objects, such as Human steve = n
