I happen to have a 12v, 22AH SLA battery sitting around, and it's just going to go bad if I don't use it for something. I want to make a 12v DC UPS to power my router. The concept is very simple, I charge the battery with a DC-DC power supply powered by a wall wart which allows me to adjust the...

I have a power supply that was removed from some kind of rack mount telecom equipment, rated for -48v DC input. (-38 to -60) Otherwise it appears to be a normal ATX style power supply. I'm going to be using it with a computer running from a 48v battery. How do I hook this up? The negative 48v...

Youtube has become my main source of "TV" these days. I like it better than cable but it seems like they still try their hardest to drive me insane. I pay for youtube premium and generally use it from a Chrome browser in Windows. Two major things driving me insane: 1. Can I force the quality to...

OK, I admit it, I suck at internet security. o_O I have a rental property with 3 units, I would like to be able to provide them with internet access. I have a 1gb fiber connection available. I want them to each have secure access, not like an open/shared WIFI network. I would like to provide...

I've got a little problem. I bought a house in a very rural area. Before I purchased, I did my due diligence and found that Centurylink offered DSL at the address. After closing, and trying to sign up for new service, the idiots at Centurylink refuse to give me service - even though the previous...

I have an older laptop that the hard drive died in several months ago. I bought a cheap SSD to replace it, but of course I have no windows media to reinstall like in the old days. I think I just found the backup I made from within windows (10) on a spare USB drive. What do I need to do to...

I have a laptop that was running windows 10 on a 500gb hard drive, divided into two partitions. The drive became corrupt after a forced shut down and would no longer boot windows. I took the drive out and put it in a USB case on another computer. The original boot partition is totally corrupt...

I just got a new Lenovo ideapad laptop with Windows 10. I have it set so that when I shut the screen or press the power button it goes to sleep. Not hibernate. When I turn it back on I see a black screen that says "Lenovo" and the dotted spiral thing windows does when it is booting. This lasts...

I'm looking for a new laptop because the 3 year old one I'm using has become annoyingly slow. 90+% of my usage is simply web browsing and watching videos like youtube, though I tend to have a bunch of windows open at once. No gaming. I used to be such a computer geek, but haven't kept track of...

I have an older S5 active phone with AT&T. Lately for some reason when I make calls I often get an annoying echo of my own voice on about a half second delay coming through the speaker. It's quieter than the rest of the conversation but still very distracting. Does anybody know what would...

Recently I downloaded a "questionable" file and it was some sort of malware. Now, about every hour or so I see a command prompt window show up for half a second, and then my search page and other browser settings are changed to some other site. Not sure what else it is doing. I am running...

I recently got a new cable modem from Comcast after my last one died. (4+ years of faithful service) The model is Arris TG1682G. Upon hooking it up and connecting with my computer, I was greeted with a Comcast activation page, where I entered my account number. It seemed to work fine after that...

I have a Galaxy S5 Active...I use the WIFI hot spot a lot. For some reason it is not working all the sudden. None of my devices can connect to the phone. I can still tether with a USB cable and it works fine. I can also connect to my home WIFI network with the phone no problem. Why can't my...

Sounds like a stupid question, but, I dropped my laptop a few feet the other day and I was horrified. It seemed to work fine for the rest of the day for simple web browsing. (besides some scratches :rolleyes: ) It was running when I dropped it. Then, I tried to open some larger programs and...

I bought a little USB amp meter because I was curious about the actual output of my various chargers. I have a Galaxy S5 Active, and I'm using the OEM 2 amp charger and cable. If the battery is dead, and the phone is plugged in and turned on, screen off, it draws 1.75A from the charger. Seems...

I got an Asus M5A78L-M/USB3 motherboard for free, I want to basically max it out with the fastest CPU and 32GB of RAM. I don't really need all that, but I want a computer that isn't going to be outdated for a while. Anyway, can anybody tell me what the fastest CPU is I can use in this board...

Trying to setup an old computer I have for an audio server. It is an Acer with an Athlon 64 dual core. It worked great about 6 months ago when I last used it. Tried to hook it up today, and the screen stays blank, and it beeps at me. I tried unhooking all unnecessary components. I tried...

A few days ago I got a Galaxy S5 active. Much to my surprise, it's telling me I walk 6-8 miles/day while I'm working. I wouldn't have guessed half that much! :eek: Anyway, I'm curious how accurate this thing really is? I figure it counts my steps pretty accurately, but how does it know how...

I have a large commercial building with 4 tenants. I would like to be able to securely share one internet connection between them. Is this possible? Can I set it up so that they all have their own individual secure connection? Would it be better to use wired connections instead of wireless? I...

I have a brand new Asus X200MA for sale. It had a defective hard drive when shipped from Asus, and they have replaced it with a new one under warranty. It is still brand new, not refurbished. Never used. Still has remaining warranty. -1.86ghz Celeron N2815 Dual Core (Burst up to 2.13ghz) - 4GB...

I bought one of these a few days ago when it was only $25, now it's up to $29 but still amazingly cheap: http://www.walmart.com/ip/Canon-PIXMA-MG2920-Wireless-Inkjet-All-in-One-Printer-Copier-Scanner-White/38067902 Sometimes they have them in stock at the store, otherwise you can get it...

I'm having some issues with my network. I have a Dlink wireless N router and two new laptops with Windows 8.1. (Asus) If I transfer a large file between them, I get a max of about 2MBps. If I transfer a file to a wired computer on the network, I can get about 6MBps. This is just a few feet...

I have a laptop and a desktop on my desk. Laptop runs windows 8.1 and is connected to a WIFI network. The desktop has windows XP and is connected directly to the router with a cable. I have them setup with "mouse without borders", so I can use the mouse from the laptop, on the desktop screen...

Finally got a new laptop with windows 8.1, and I absolutely hate it. I open a lot of copies of Chrome from the shortcut in my taskbar. In Windows XP, every time I click on the chrome logo, I get a new copy of chrome open. In 8.1, it just maximizes any windows I already have open. I know if I...

Yesterday I bought a new Asus K200MA laptop from Amazon.com and had it overnighted. I needed it today...and it's broken. The damn thing only boots straight to the BIOS screen. Exit, restart, back to the BIOS over and over again. That's how it came out of the box. I talked to Asus support...

I recently bought this Canon scanner/printer at Walmart for just $29: http://www.walmart.com/ip/Canon-PIXMA-MG2520-Inkjet-All-in-One-Printer/28773460 I am very impressed with this printer for the price. As good as anything else for documents. It came with two ink cartridges - #245 and #246. The...

I have an android phone. I have Google voice installed but I don't really use it. Lately my phone has not been ringing when people call, no missed calls, nothing. Today I happened to have gmail open on my computer when somebody called and my computer rang! I DO NOT want any calls forwarded to my...

I have a computer running windows 8. I'm using a USB bluetooth adapter to send a signal to a bluetooth audio receiver. When I connect the bluetooth device, the regular line out jack on the back of the computer stops working. Is there a way to get sound from both at the same time?

Long story short I want to be able to control the output of multiple relays from a custom web page through WIFI. I need to be able to control a light for example from the browser of any device on the local WIFI network. I find a lot of relatively cheap devices like this on ebay...

I want to get an 8" Windows tablet. I've searched and searched but I can't find any with a sim card slot or any option for mobile broadband. What gives? Is there such a thing? That seems like the top thing people would want in a tablet that size. The Dell Venue 8 Pro has claimed a sim card is...

I have a large shop/warehouse spread out over two buildings and 3 floors for my business, and I'm always listening to music. I have a bunch of various amp/speaker systems scattered around, and I usually plug my phone into whichever one I'm closest to. I want them all to play the same thing at...

I'm trying to get an older computer setup, it's an Athlon 64 dual core. (Acer) I put two 1GB sticks of memory in, and booted up windows 7. Windows reports 2.00GB of RAM, but only says 768 MB usable. (256 is used for onboard video) Can anybody tell me why 1gb of RAM isn't being used?

I'm trying to set up an older computer that currently only has 512mb of RAM. It is an Athlon 64 dual core with 3 slots. The memory that is in there now says "PC2 4300", if I search for that on ebay there isn't much. Google says that is the same as PC2 4200, when I search for that I get a bunch...

I have a few old LCD monitors that I would like to use as wireless displays for a few WIFI cameras I have as cheaply as possible. Can anybody tell me what the cheapest device to do this with is? I can get various type of Android "boxes" on ebay for $20-30, but they are all HDMI output, my...

I have a "vintage" Galaxy Note and I've been having a lot of problems with the GPS lately. It seems like it has been getting worse and worse. Today I was standing outside, on a clear sunny day, looking right up at the blue sky, and I couldn't get a GPS signal. Waited for a good 10 minutes...

I have an Android tablet and an Android phone. I want them both to have the same google calendar on them. Under settings, they are both set to sync to my gmail address, but they don't. On my phone, if I edit the calendar, the changes show up on my PC, but not on the tablet. If I change anything...

I'm looking at buying a new laptop with no VGA port, but I want to use an external LCD. If I got a monitor with HDMI, can I connect the monitor to the laptop's HDMI port the same as a VGA connection? Would the resolution be the same?

Long story short - I want a second number that will work with my phone. (Galaxy Note from ATT) I know there are several different apps out there that will give you another number, and usually you have to buy minutes to use it. All I want is to make a call and have the caller ID number show up as...

I have a Galaxy Note phone and I'm getting tired of carrying it in my pocket all the time. I also don't really like how it functions as an actual phone. I am however constantly on it checking my email, text messages, and a few websites. I'm thinking of going back to a flip phone and getting a...
