  • PCIe Gen3, PCIe Gen5?

    Just bought my first computer, don't know much about them. Before I spend big money on solid state drives, I noticed my motherboard has PCIe 5.0 slots. I keep seeing that the PCIs are all backward compatible.  Does this mean if I buy a PCIe 3.0 ssd, I can plug it into the PCIe 5.0 slots without an adapter? I understand that it will not increase the speed, but my graphics card has put my 3 slot in a tight position.

  • Moving a levitating object using ferrofluid and magnetic force.  ?

    Is it possible to move a levitating object (or floating in space) that spins ferrofluid at high speeds in a circular path around the object by using a strong magnetic force within that object to upset the balance of centrifugal force in a controlled fashion?

  • Electric meter wrong setting?

    An electric meter was installed in a rv power pedestal. This pedestal has 220v service but only provides the Rv with 110v 30amp service. When the meters where installed, the installer confused the output service with the input and the meter was set to read 110v instead of 220v service.  The normal electric bill for RVs run around $80-$120, the meter was only reading $15 - $25 month. Is there anyway mathematically to figure out the true reading?

  • hyper-sonic nuclear jet propulsion ?

    To my very limited understanding, the Russians are basically spraying hydrogen across a super heated nuclear element the in turns multiplies the explosion factor 10 fold......maybe I a wrong. 

    Question is how hot is this pellet? Can you take a jet or rocket engine and use a ceramic heating element ball powered by a big lithium battery at the combustion chamber where the fuel in ignited to achieve this increase of explosion?

  • Why would I read 121v and 112v on the end of a campground row when at the substation it reads 119v and 119v.?

    I understand the voltage drop is from usage (too many 30amp rvs on one side), but why the rise past 119v?

  • 2004 Mini Cooper S, High pitch whine noise.?

    I own a 2004 Mini Cooper S and for the last year and a half I have been hearing a high pitch intermittent whine. This is not a mechanical whine, nothing to do with the supercharger, engine or transmission. It does not change frequency with speed or engine. It sounds electronic like a speaker. Here's the thing, the pressure inside the car affects the whine. Roll the windows up and no whine unless I am traveling around 75 or 80 with the ac on (fresh air mode). Crack the windows and it starts, ac on or not, radio on or not, I have not found anything that else that affects it. It's not loud, you can only hear it with the windows cracked and the radio turned off or real low. Its very high pitched, very hard to pinpoint. I think it has always been with the car since I bought it 2 years ago, I just never heard it because of all the road noise the 17" tires where putting off. Was wondering if anyone else has the same problem or a fix?

  • I need a compact and cheap way to make a tilt switch light a semi bright led bulb that takes a button to reset.?

    I need a compact and cheap way to make a tilt switch light a semi bright led bulb that takes a button to reset and turn off until the tilt switch is activated again. Basically I want to put a tilt switch on a door that flips down, have it turn on a led bulb that stays on till you hit a reset button. All of this has to be power by batteries.

  • Can a Canon network printer be hacked for internet.?

    I own a campground, I have two wireless routers that are throttled back for our customers. Basically these two routers are access points that go into a wired router that assigns ip addresses. I have it to where it assigns address 192.....002 - 060. In this ip range the download is throttled so no one person can hog all the bandwidth. I have a third access point that only the office uses. It runs into the same wired router, except that I have the wired router set up to recognize the office computers mac address and it assigns a specific IP that it between 061 - 099 so that they are not throttled back. This seems to work great. The other day I checked the wireless office router and the mac address for our printer read that it had downloaded over 1gb overnight. I know the printer can be seen over all networks but I never had a problem with people using it so never worried about it.

    Can the printer be hacked and used for the internet by one of our customers to bypass the throttled bandwidth???

  • Changing network IP address from static to auto and back again?

    My wireless network at work requires a certain static IP address that is in the 192.168.2.... range. All the others (home school etc..) I need to reset the adapter back to automatic. I use windows 7. My question, is there a way I can have it sign on to work with a static ip, and have it automatically change back when signing on to any other network without changing the adapter settings every time. I would not mind it as much if it did not loose all the info for the static network when I turn back to automatic, but every time I have to reenter the ip, the subnet, the dns.....

  • Can I use a ground rod to provide a neutral?

    I am changing over some 220V street lights to 120v fluorescent lights. I've done 4 so far and have had no problem using the ground (no neutral provided) as a neutral to power the lights (105watts). Now I have one that reads 120v until you put a load on it and drops to near nothing. I know I don't have problems with either hot line so I know that the ground is not providing. My question is (before I did a 50 foot ditch to the nearest neutral) can I use a ground rod to provide the neutral? Lights are only 105watts.

  • Electrical outlet wiring question?

    Opened an old power box today that had a regular 20amp 2 outlet receptacle in it. I need to use it and went to replace the receptacle and breakers (40 years old). They had it wired to two separate 20amp breakers by cutting the middle of the (hot) tab on the side so that each outlet on the receptacle could draw its own 20amps. The wiring is sufficient in size, but is this (up to code) and can this overheat the receptacle?

  • EXCEL Trouble with (IF)?

    Trouble with an (IF) issue, I am working on 2 different sheets, basically I want the second sheet to use a value from a cell in the first sheet if a value in a cell of the second sheet is greater than 1, if it is not greater than 1, then I want the value to be zero.

    This is as close as I got, (my sheets are labeled 1,2, 3 ect)

    =IF(C8 > 1), "1!H23", "0"

    The value is zero when c8 is less than 1, but instead of showing the value of h23 on sheet 1, it spells out 1!h23 in the cell. Help......Please
