I am trying to do a tutorial where I require screenshots of the amazon fire TV steps. Here are a list of my steps that I require a screenshot for: 1. Navigate to 'Settings' 2.Select 'Systems' 3.Select 'WI-FI' 4.Select your WI-FI network and forget WI-FI network by pressing the button with 3 lines on it. 5.Press the select button. 6.Select your WI-FI network. 7.Enter your WI-FI password and Click on 'Advanced' 8.Now you must enter the IP address for this device: Start by entering the first three digit groups from the IP address of your router. For example, if your router IP address is "", enter "192.168.1." For the last digit group, you can typically enter "200" so the final IP address for the device would be "" In some cases you may need to use another number other than 200 if another device already uses that address 9.For the Default gateway, enter the IP of your router 10.Input '24' for the 'Network Prefix Length' and Click 'Next' 11.Enter the following public DNS addresses: DNS 1: DNS 2: 12.Click 'Connect' and you're done.

my flip camera won't work, and I need some files.? Answered

I'm thinking maybe one of the files is corrupted. if this is so, then replacing it should fix it. but I can't find anywhere to download them. so if anybody has a flip classic camera, then I would like the system files off of it. just plug it in and copy and paste the root to another folder and email it or upload it or something. just some way to get it to me. or, if you know a different way to fix it, that works too.

Can I use a DPDT Toggle Switch, To switch a Transformer output from series to parallel?

The project originally calls for a Radio Shack 273-1512 but I needed a smaller pcb though hole mount transformer for my use. My transformer outputs 24V @ 1.5A in Series and 12V @ 3A in Parallel. Is it possible to wire up a On-Off-On DPDT Toggle switch so I may flick back and forth between the two? If so, would you be so kind as to provide a diagram. I have a feeling I am over thinking this and just need to take a step back to see the whole picture. I thank you for your help and advice in advance.

Need Help writing a Star Trek themed Arduino code

Hey Folks. I really need help  writing an arduino code to control a star trek model i'm working on. I don't really understand programming but I'd really like if anyone can help out. The code is supposed to use 2 momentary switches. When the main switch is pushed it will activate some leds in sequence, the last 2 will fade on one after the other in the same manner, this will be called the 'startup mode'. Then when the second momentary switch is pushed (while the main is on) it will 'switch modes' and the 2 leds that faded on one after the other initially will now fade off or ramp down at the exact same time then 2 more leds will fade on or 'ramp up' in their place at the exact same time. Finally, when the button is pushed again it will simply switch back. A video demo shows what im talking about with some very small differences. Any help would be appreciated! This video below shows what Im trying to do. Please see from time frame 0:35 to 0:54 which shows the 'start up sequence' described above. And one more showing the actual model i'll be working on and the startup sequence with the movie timing.

Palm Universal Wireless Keyboard disassembly?

I'm toying with the thought of adapting my Palm Universal Wireless Keyboard to work with Bluetooth.  Currently, it sends irDA data at 9600 baud.  This should be decodable using an xmega's usart which has an irDA mode.  One could even bypass the IR emitter, as there are exposed contacts in the base where one can catch the signals prior to irDA transmission (at 1.5V high  / 0.5V low levels). My question is: Does anyone know how to disassemble the keyboard?  I don't see any screws anywhere.

Batteries and LED light modules - correctly powering for maximum life

Hiya, I need to power a LED strip of 3 LED lights with batteries. The LED box says it is a 12VDC light module, and on the back of the box it says the Input Power is 0.0453A. My limited understanding is that I should use a 9V battery plus 2x AA battery (I have limited space - a 8 AA pack wont fit inside my project) that correct? I need to know how long these batteries will last - if it is less than 10 hours can you suggest another way of powering it? I'm incredibly lost and very new to understanding all of this! Thanks in advance.

how do i make nitrous oxide? Answered

Having seen mythbusters, i am curious how the stuff is made. during my internet searches, it is made by heating ammonium nitrate to ~250C. from watching the episode, i know there is more to it than just that. I am under the influence that everything else that was done was purifying the stuff. i am mainly curious about how this is done and whether or not the stuff is toxic, dangerous, addictive, or anything else of the sort that would make it bad to breathe. I will be honest, if the stuff is not dangerous, i will slowly and carefully attempt to make the stuff and maybe breathe a little of it in the curiosity of what it does. for those who don't know, nitrous oxide is also called "laughing gas."

How to control a RGB LED with a button or knob?

I would like to create an led powered by batteries that can change from Green to Yellow to Red and off.  I can use either one RGB led or 3 different leds (Reg, green and  yellow obviously) If having a yellow light makes this more challenging, then I can change the yellow to blue.  Do I need a controller? Can I just use wires and resisters? I would like to keep this as simple as possible to start out.  The whole idea is to have someone be able to either turn a 4-position knob, or push a button to change the color of the LED.  I saw another question on Instructables about this topic, but I could not find any solid answers.  Thank you for any help you can provide.

Servo Help!

First of all, I'm not the best with Technology projects, just putting it out there in case its an obvious answer. Anyway, I have an arduino project that im working on. All it is is a servo that spins after 24 hours, I thought it would be a simple project (I've worked with arduino a little bit) and I wired it up correctly, I'm sure of that, but after I coded the program, the servo wouldn't spin! It just made a dull buzzing sound. At first  I thought it was my program, so i tried just about every basic "sweep" program i could find online about servos. Every program had the same result, a faint buzzing sound and no spinning. Next i thought, maybe the 5v wasn't enough to power the microservo, so i used a external 9v and ended with the same result, buzzing, no movement. Can Anyone Help me?! Please! Is it just a simple solution? Or is my arduino micro controller not working! Please help me because i would like to enter the project in a contest that ends soon! Thank You!

Dial-up internet server

Hi everyone, I am trying to connect my Sega Dreamcast to the internet with it's 56k modem, without using telephone lines. From what I understand, I need to connect my my Dreamcast to a tone generator, then to a USB modem plugged into a laptop with which to forward the connection over wifi. My question is: Is this is a plausible solution, and if so, could I simplify and shrink this set up. Ideally I would like to figure out if I could build a tone generator instead of buying one and how can I replace the laptop with something like a raspberry pi. I think that once I figured out how to forward the connection on my laptop, it would be fairly straightforward to do the same with a raspberry pi. I would prefer a relatively compact solution if possible. Thanks in advance for any help or thoughts.
