?

How can i convert the laptop's optical bay into an extra hard driv that can be switched on and off on demand so its not running all the time?

Im using a SSD as the main drive.

My galaxy S4's vibrator stopped working ever since i changed the screen and when i do a self diagnostic using *#0*# the screen goes black when i press the vibrator test.. But my phone vibrates when i pick it up if i have a notification?? Any idea how to fix this?

so today i rooted my phone (sgh-i337) and ever since that i've been getting "system UI has stopped" message. so i removed the root using superSU.. that didnt fix the error message, not even factory rest or hard reset.. so should i flash MK2 firmware using odin and how safe is it?? i just got this phone back today after bricking it before..

I got a circuit board from a bluetooth headset and im trying to connect two 6ohm speakers to the headset speaker connectors.. The circuit's output is about 2.6ohms when playing music... Is it possible to increase the ohms or can i just connect the speakers without any problem? Thanks

If I Flash my Galaxy SGH-i337 with i9505 would I still be able to install new android version updates? The reason I want to do this is because I bought this in america but I live in Ireland so I can't update my android without connecting to AT&T servers??

I live in ireland and i bought this unlocked AT&T galaxy s4 on ebay. It has the base band version AMDL? Is that the latest one or is there a new one? And can i update this phone in ireland? Im using a prepay meteor sim now

If not, what are the effects of charging a lithium-ion electric car battery while being used?

So ive loved this girl for about 3 years and she loves me as well.. Our parents are frends but they have theat usual family problems between them.. So shes afraid to start a relationship with me becos she think we wont be allowed to be together in the future.. She agreed to start our relationship when we r in college but she still has doubts about us.. Shes very innocent and doesnt want to disappoint her parents but im willing to do anything for her.. So any ideas what i should do? Should i leave her alone until college ? Or should i try to convince her to love me again and dont worry about her parents?

I've tried with 2 brand new dock connector and two home buttons but still doesn't work. currently im using assistive touch.. any idea how to fix?? PLEASE HELP.. thank you

Hi i made this circuit diagram http://img403.imageshack.us/img403/7531/cimg6621x.... of a touch sensitive alarm using this diagram from vishaworld.com http://img585.imageshack.us/img585/3931/k43.png (original diagram). I want someone with good knowledge of electronics to analyse both of these circuits to see if my diagram is wrong or any faults in it. it is an exact copy of the original diagram but with the IC in the center.

I also want to know whats the component pointed by the red arrow is? i think its the ground but im not sure.

Thank you so much :)

go to this link and you can see a very straight forward circuit diagram. www.epanorama.net/circuits/micamp.html

But i have a problem figureing out how to connect the battery because as you can see, it only connects at one point? Could some one please help me with this. And btw what does the slanted letter E at the bottom of the BC547 represent?
