My Windows 8.1 Acer Predator has started booting to a black screen with the cursor visible and movable.
Acer's Alt F10 gets you into tools but none of them recover the disk.
If I take a backup drive made over a year ago and plug it in the computer boots.
If I then connect the failing drive via USB connection I can, by running Diskpart, see the hard drive and all its folders.

Connect to the drive and run all the dos utilities which claim to do things like fix mbr but nothing.

At my wits end.

Even when I create a recovery USB drive it fails my guess it has to be from the original drive but wait the backup disk is the original drive which was used to create the current drive. Which worked for the year it was cloned.

Going to get away from this thing for couple of days and see if I can find a way to recover the boot portion of the failing drive.

Any ideas or approaches for this end result are welcome.

+Fr. Robert Ballecer, SJ Thank you Padre and no didn't get the DVD's . Any help you can offer is appreciated. Let me know what you need from me to get the media in question.
Have to ask will the DVD's restore the boot portion of windows or restore to original factory settings?

Whipped up the 140mm adapter for 6" air filter canister I mentioned earlier:
https://plus.google.com/+StedeBonnett/posts/MBD9rcZwXeG

This is specifically for round 140mm fans like this Noctua NF-P14r. They are very quiet and have higher static pressure than 120mm fans of the same airflow (this one is ~80cfm). These are usually <$17 each and have a 6-year warranty
http://noctua.at/en/products/product-line-redux/nf-p14r-redux-1500-pwm/specification

it uses a slightly smaller inside diameter than the fan shroud to ensure you can get a good seal (with silicone or similar).

https://tinkercad.com/things/hONVyQsMAIh

I printed all of these at .3mm layer height with 20% hex infill on my XYZ davinci 1.0 Pro with Hatchbox black ABS filament. You can see the 9mm 'brim' on the first layer that helps keep it from lifting off.

So I think i may have figured out my earlier problem with Synergy.

If I go to the configure server button I thought was a dead end and drag a new screen onto the grid I am given options to edit the new screens settings. I am guessing if I name the screen the clients name and for good measure add the clients name as an alias it should work.

The first pic is from the computer I am trying to set up the others are from a different computer I am using to find what I am missing.

It's been awhile since I setup synergy, but I think it's failing to connect. :) From captain obvious.

The first thing I would try is disabling the firewall just to see if it is being blocked. If that doesn't effect it, check ip address and username/password. Unfortunately that's all I can think of.

I have been using another program called input director. Its not as finished as synergy but I think it works out better. Just incase synergy proves fruitless.

Got a question for Yoshi, you looking to do a revision of the Yoshi box, when Nintendo re-releases the HDMI Nes machine running, the wiiu, Nes, PS3, ps4, Xbox 360. Xbox one

Actually it would be interesting to see If Nintendo will go with a different design to incorporate SNES with both a cart and cd slot and redevelop the SNES DD and the n64 DD. Not really sure if the actual Nes will support 1080.

Realistically the best resolution you will get from the Nes, SNES, cube, is 720 p s-video resolution.. As that was what physically available.. That's from the multi port vid out..

I wonder if sega would come to the ball park and do the same the SMS, mega drive and the other cart and cd based console system..

I would love to see 12/24 vdc console ports..

I bought https://smile.amazon.com/gp/product/B008ZNWOYY/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 to use a USB charger power supply in my car that is always on for my Note 4 would I want to just short the data wires or would I need to put a resistor to make it work as a charger?

This guy didn't even send a signal to data pins and I don't know that it would be necessary. https://youtu.be/RVUbIMncjqM

For quick charge, I thought there was circuitry in the phone that sent a signal to the charger to say it's QC compatible (maybe the signal was on the data pin?). That would prompt the charger to send a higher voltage.

This Android Authority post says QC 2.0 will do 5, 9, 12V and up to 18W. Same article says QC 3.0 will handle 3-20V, but with the same 18W max. http://www.androidauthority.com/quick-charge-3-0-explained-643053/

Is this possible

Looking at this paperwork

"SOL 1064nm User's Manual 6 to 40 W (EN) 2014-12.pdf"

Can I wire a 5 volt power supply to the digital pins 1,3,14,15,22 and variable resister POTs on the analog pins 12 and 20?

The digital output pins are for system checks and analog output for monitoring amps

Digital Pins 5,6,7,8,9,10. And Analog out 4

Without a computer at all or is a computer required for digital outputs?

I may need a PC for the rs232 or is that just for remote monitoring and will do not need that if we are running on sit.

In all honesty, if you are going to use pulsing, use a micro controller with a dedicated hardware  PWM.  They are free running and the program loop has no effect once configured and started.
(I'm sure the arduino has at least one)  But in typical arduino fashion any pin can do basically any feature via software.  You really want to use the on board/hardware feature there (especially for a medical device)  I haven't looked at the datasheet for the atmel(?) chip, but know the PICs definitely have them (that's what I cut my teeth on)

I might have been (probably)  wrong on the pin 20 needing a pulse too.  Look a little further down and you will see the timing chart, of how things need to go.

This is a 120mm to 6" duct fan adapter inspired by the 4" one from KH224.
https://twit.tv/shows/know-how/episodes/224?autostart=false
It fits on the 6" version of the filter linked from the episode. This is actually my first attempt to use tinkercad, and there was one minor alignment issue with the fan holes (they were mysteriously out-of-place by 0.39mm) that is fixed in the file now:
https://tinkercad.com/things/6fEIuDhbPiS

The upper spherical duct can still be used with a second fan, of course. I am also going to make a version for the 140mm Noctua NF-P-style fans (which use the same hole spacing as a 120mm fan) once I figure out how to get a good seal around it.

Shown here with a 120x38mm Panaflo L1A

Could also use something like Llama or Tasker to just disable cellular data when you're at home to see if that makes a difference. Llama (=Llama Is A Mobile-aware Assistant) used to be my go-to for location-based profiles. Like, when I am at home, turn on ringer and Wi-Fi. When at church, turn off ringer and turn Wi-Fi on. When at work, turn off ringer and Wi-Fi. Etc. It uses the cell tower IDs to determine your location - so not overly accurate but saves on battery life.

Just set up a test tor hidden service. (mainly as a POC)
The cool and scary thing about it is, that you don't need to open any ports on your router.  All accessible from behind NATs on both ends.

Stuff on a Pi, leave behind hidden at a hotel or such, and you got a cool fairly anonymous jump off point.
(don't think anyone really trusts TOR for bulletproof anonymity)
But better then a reverse ssh shell

Wow, ZeroTier seems really cool and exactly what I think a VPN service should be like. I like the idea of connecting devices outside of your home network. I don't mind opening a port for OpenVPN, but many don't know what that even means.

Pondering setting up a back up internet connection.
Time Warner goes through spurts of outages here.
Plan is to hop on via WiFi to a tethered connection.

Fly in the ointment is that my router (Cisco 2851 at 192.168.1.1) is not my DHCP server.  I'm using one of my Synology NAS's for that. With a very short lease time: 5 minutes

So ideas for a relatively seamless  (for the clients) hand over?

Just occurred to me I can add a WiFI adapter to the NAS with the DHCP and have it route.   (hopefully it will update the default route.)
Well quick test shows not what I was looking for.

+Ben Reese  I'm not too interested right now in learning load balancers :)
Think I'm only going to ponder and research a bit until after defcon.  Then it becomes a short list to-do item.

If you go to the geek my ride website you can see more. The video I linked to is about 7 years old. He doesn't demonstrate the RFID in the video but I know it's in one of the videos

OK, I need one of these (guess who has a drone stuck in a tree?). But I'm guessing I can make one for MUCH cheaper. Any thoughts on a parts list and build tips?:
http://dr-unit.com/
Your drone is stuck in a tree, get it back yourself with the Drone Retrieval Unit. Safely, quickly and as many times as you want.

I'm looking for some hardware that I can use as home brew NAS (probably using FreeNAS). I'd like it to be low power, have 3-4 3.5" SATA bays (hot swap is unnecessary but ok), and preferably 2 nics. I'm hoping to spend up to around $500 for a 2TB useable space.

I wasn't sure how current-day Pentiums compared to an i3. The NAS probably doesn't need much processing power though.

Quick question for the people that purchased the HobbyKing 250 fpv kit, did it come with cables to connect the receiver to the kk2.1 flight controller? I purchased two kits and they didn't come with cables.

Not anymore. The first kits did, but then they stopped including cables.

So, I know next to nothing about graphics cards...am I going to have faster performance with internal graphics or an old Gforce 9400 GT I picked up?

I also picked up a few $5 old AMD cards from the local university surplus, and in wondering the same thing there.

Or, the question more generalized: is any graphics card better than no grapuuxs card?
