I used this Note 5 for 2+ years with a great experience.  Great phone - large bright screen 5.7" 2560x1440 pixels, fast 4GB RAM and 32GB Storage, 16mp camera.   All good except.. battery life is terrible.  Time for an upgrade.  
Should I stick with Samsung and go with Note 8 or what would be other recommendations?  

Thanks in advance.

Hi Experts

I am having a problem trying to diagnose a problem I have with a simple high side switching circuit that is on a PCB. It works fine on a breadboard. The schematic is below. RL is a placeholder to where the rest of the circuit goes. The rest of the circuit I dont think matters because there should be no current draw if the mosfet if off. Please see attached schematic.
It is supposed to work like this. I have a microcontroller controlling the power to the circuit. To turn on the power I set the IO pin high and the Mosfet to M1 turns on and so grounds the gate of M2 and so switching M2 on. This all works fine.

The problem is that when I set the GPIO low I get 0V at the output of RL but if I measure the curent draw its around 150mA. This should be 0 or maybe just a few uA. Shorting R2 to ground has no difference.

I am having trouble finding out out to troubleshoot this and why this would be. Any help in how I can find the problem would be great.

Are these symptoms indicative of a faulty mosfet or something else.

Thanks!

The above was gifted. what would be most ideal specifications to aim for this (for elec wire to go with this for outdoor use)? when searching for outdoor electrical wire, below are specs are needed to be filtered thru.. can you guide how you would choose in the below availability..

Cable/Wire Type: Thermostat Wire,UF-B
Guage: /10/12/14
Conductor: 2/3
Allowed Amp: 15/20/30/50
Solid or Stranded

ideally, more durable to last a few years. (mainly for summer, and possible little snow blower too)
also ideal to have feature to roll it up when not in use

I have a second hand SONY VAIO Series E notebook with Windows 10.

Last night, I ran it on battery and at 5% battery it shut down on its own  (not hibernate)with a little pop sound.

I immediately attached the original power charger and there was no charging.

My first guess was that either the motherboard or the power adapter gone south as there was no green light on power adapter and no charging light on notebook.

I opened up the three pin in the socket of the power adapter and saw there was a 3A fuse itself.  I replaced the 3A fuse with a 5A fuse and there was green light on power adapter. However, when I attached the power adapter to the notebook, the green light turned off within 15 seconds and I can confirm that the power adapter is dead now from the smell.

The good news is the notebook can be powered on after 15 seconds of "charging".

I have forgotten all my lessons in electronic circuit.

Is my motherboard having a problem? Will it burn another power adapter?

Why changing the fuse will burn the power adapter?

I have several new Dell laptops that explicitly say they take DDR3L 1.35V memory. - Latitude E6440, E5550, E3460...
I have Patriot Viper PV316G160LC9SK so-dimms that are 1.35V but say they are DDR3, not DDR3L.  Can I use the Viper memory in the  Dell Latitude computers?
Thanks,

Hi EE,

I have attached multiple sensors with my Raspberry Pi. I want to power off couple of those sensors from my mobile. I can now only start / stop sensor data reading from my application, but it do not power off / on those sensors. However I can reboot my Pi which power off all of the attached sensors.

My question is, "is there any way to power on/off selected sensors which are attached with my Pi"?

Regards,
Roy

There is a "Facebook", but I've always felt there should be a "Familybook".  We don't live in isolation of each other, we have families and each member of the family has personal electronics which can take and view pictures and store music tracks.  In the pre-smartphone home, these were easily shared between family members.  You could reach in the bookshelf in the den to view photos.  You could borrow your sister's Metallica album, etc.

Now that you know my mindset, is there a hidden way in Google for my family members to share our Google cloud files (Google Photos and Google Play Music) between family members?  The only option I have seen so far is to literally log out of your account and log in to your family member's account.  I know you can create a photo album and make it available for "public" or "family" but this is not what I'm talking about.

As an example of my intent, my wife and I are going on a cruise next month.  I will be taking photos with my phone, as will my wife with hers.  When we get back, we (meaning she) wants to merge them then go through and pick out the best to be made public.

Ideas?  Hints?  Compassion?

TIA

Dear experts,

I am a novice in raspberry pi. I want to make a door lock which should be unlocked only when it detects presence of myself within a range not for others.

Is it possible? What type of sensors need to be used for that? Any tutorial or advice?

With regards,
Roy

Is it ok to plug my UPS into my surge protector?  Any electrical engineers out there?

I have the following UPS: APC BR1500G
(http://www.apc.com/shop/us/en/products/APC-Power-Saving-Back-UPS-Pro-1500/P-BR1500G)

And the following Surge Protector: Tripp Lite HD10DBS
 (https://www.tripplite.com/isobar-10-outlet-home-business-theater-surge-protector-8-ft-cord-3840-joules~HT10DBS/)

I'm not trying to "daisy chain" extension cords here, but trying to protect my UPS from Surges.  Unfortunately the built in Surge protection on the UPS isn't stellar.

Thanks

I'm in a country that uses UK power system (ie 220-240V).

I'm looking at Brother MFC-J480DW & MFC-J680DW which is
selling for about US$143 & US$168 here while in eBay, they're
listed for US$94 to US$110 in eBay:
http://www.ebay.com/itm/NEW-Brother-MFC-J485DW-Wireless-All-In-One-Printer-Scanner-Copier-Black-/132041083447?hash=item1ebe430a37:g:9-UAAOSwux5YWr7t

Our local Brother says the eBay units are under Brother USA's warranty
(not international warranty) & uses 110-120V & local Brother can't service
them in the event of faults.

I ever bought US electronics & use converter but in most cases, the equipment
got burnt or don't last long (eg: bladeless fan & white noise generator).   Should
I take the chance with Brother MFCs or has anyone tried them in a UK-power
system country before with good success?

Attached is CAN Transceiver Datasheet.  This IC is wired in our Microcontroller based Electronic Control Unit.
 
What will be CAN High (CANH) and CAN Low (CANL) Voltage when CAN Transceiver is in sleep mode?  

To verify these voltages are correct in sleep mode, measure CANH with respect to ground?   And measure CANL with respect to Ground?

Hello,

I have a Samsung-UF6470 Smart Tv.
I downloaded Samsung Smart View so as to watch films from my computer.

However most of the times the subtitles cannot be seen (9 times out of 10).

-the subtitle name is exactly as the film name (except the extension of course)
-I tried to drag and drop both the film and the subtitle file
-I also tried to give the whole folder in which the film and the subtitle files are

What can I do? Is there an alternative software which handles the subtitles well?

Thank you.

I got fr Amazon the Lasko bladeless fan & it was working for 1 week on my local
220V to 110V  100W converter in my UK power point: just that after 30 mins or so,
the converter would cut off & feel rather hot.  After a few mins rest, it wud work again


http://www.ebay.com.sg/itm/1600-W-220V-TO-110V-FOREIGN-TRAVEL-VOLTAGE-CONVERTER-INTERNATIONAL-/181746563714?hash=item2a50f07a82:g:92UAAOSwl8NVXrHb
I thought the 100W converter cant support high enough wattage, so I got the above
from eBay which supports 1800+ Watt : the contact point of the Lasko power plug's
pins to the converter is not that good though the Lasko runs with a much stronger
wind (& noise too) but after a minute or so, I heard a pop sound with a burning
smell : the Lasko doesn't work anymore even if I go back to my local converter.

Is this just a fuse that I could replace to get the Lasko fixed or likely some major
electronic component is now burnt?

I have a Qosmio X870 laptop with blu-ray player,  using toshiba blu-ray disk player,

doesn't seem to do anything now,  tried multiple discs, and reinstalling it, updated to latest version.

at the start of this it didn't allow me to pick resume fora disk i previously had in the drive for days that i was in a the middle of watching

windows media player wont play them either.

I believe i'm missing a codec or something,   this happened before,  i believe i reinstalled a microsoft visual c++ program the last time to make it work?

any ideas?

I'm contemplating Dyson's alternatives & looking at the above 2 items.

Q1:
For the top item, it says Supply Air Rate is 30L/S  while output is 450L/S (I presume L/s
means litres/sec) : how is it possible that input is not equal output ?  From physics
point of view, they should be the same, isn't it

Q2:
are the 2 items above the same item?  Bottom item did not indicate the measurement
/diameter of the fan

Q3:
Any tried them before & can comment on these bladeless fan's quality (breakdowns,
noise level ie should be quiet enough not to disturb sleep at night & the air flow could
reach say 4 meters away at top speed?)
