I'm working with a friend on developing a USB stick with a reverse-bias transistor to create random bits. We have a working prototype, but I'm worried about how to 'correct' the samples.

This design has a sort of 'floating ground' on the signal being sampled, and we can move it's center up or down to affect how many ones vs zeroes there are. We can tune it to be exactly 50%, but I'm wondering how much fiddling we can do and still call it 'random'.

Is sampling 1000 bits, checking if they're 50/50 ones and zeroes, and then adjusting up or down the way to do this? Should there be a bigger window, smaller window, random window, or is there something more sophisticated we can do?

I'm just starting out. Only a few nights in - several hours each night - and I've learned a ton about the night sky. I've star-hopped around to find several Messier objects, and even though I live in a pretty light polluted city, I'm having fun. (20x80 Cellestron Binos + Good Tripod/Mount)

But I can't see the rings of Saturn.

My end goal is to get a scope that is suitable for AP and will let me see well beyond a faint smudge in DSOs. Or maybe I'll just go with a honkin 16" or bigger dob. I don't know exactly what I want yet, but either one costs a ton of money and I'll have to save for a while. A long while.

So while I save up, I want to get a scope that will let me 'scratch that it

Total noob here. I've been doing my reading, which led me to look at some dobsonian telescopes, but I'm concerned about my lack of storage space. Now I'm considering a pretty good set of binocs.

Online there are Orion 9x63 and 15x70 (parts 09327 and 09463) for the exact same price. What are the differences here? Does anybody have another recommendation in the 200-300 dollar range? If it matters, I'm planning on picking up a tripod.

I'm trying to set up a dedicated server for some friends, but I just can't get the thing to work. I did a fresh install of windows 8, installed all the updates, configured port forwarding on 27016, made sure space engineers is allowed through the firewall, but still there's no joy on the server list. What other troubleshooting steps are there? A little help would be awesome.

My fiance and I bought an English Mastiff yesterday. We were actually looking for a border collie or similar breed, but I've always admired super-large breeds and we absolutely fell in love with this dog. He's exactly 3 months old and weighs ~25 lbs.

Unfortunately, we might have jumped the gun a bit. We're prepared to give this dog whatever it needs, but I'm concerned that we just don't know what's best for it.

Specifically, what kind of food should we be feeding him, and how much? I'm used to medium sized breeds, so I have no idea how much this animal should be getting, nor how often.

Also, I read at some potentially disreputable websites such as yahoo answers (which is surprisingly

I've done a little bit of googling, but I’m not able to really understand what’s going on with the coaxial tap in my wall. If somebody here has a little bit of expertise and can explain/clarify things it would be great.

I’m trying to understand what kinds of signals anybody would be able to see on a typical coaxial tap. Since most of the infrastructure was originally intended for one-way broadcast of television, I assume the cabling is designed to support pretty high bandwidth. If a television signal in the coaxial is the same as over the air, then 6 MHz per channel multiplied by ~100 available channels would eat up about 600 MHz total. This way, multiple houses would access the same ta

I've been thinking about getting a new (or used) car in the next 6 months or so. After a lot of thought, I came up with a sort of algorithm to figure the 'price' of the car. An example will follow. I'd like to hear any feedback that you gurus might have. Although I haven't looked at a ton of models yet, I think this might be a strong argument for purchasing new cars instead of used ones.

1. First, tradequalityindex.com says that, on average, a Toyota Corolla will get 134,000 miles before the end of its life.

2. A new 2016 Toyota Corolla LE has an MSRP of $19,500 and zero miles.

3. A 2009 Toyota Corolla LE from Carmax (in my area) with 63,000 miles is selling for $11,998

Not sure what chipset drivers, although I did run the software to download all the latest updates. I will investigate further if its relevant to this problem.

Web browsers (chrome/firefox) are commonly running when the problems start, but I'm also on web browsers most of the time so who knows. The problem also occurs when in

I graduate next May with my BS in electrical engineering. All I need to meet my undergrad requirements, though, is to finish my senior design and take chemistry. So I started taking grad level courses and other random UG courses that look neat or whatever.

I love everything about my intro to crypto class which is in the CS department and at the grad level. I would love to take more classes on it, or even pursue it as a career if possible, but this is literally the only class on cryptography at my university. I asked the math department what other classes might be relevant, but I'm being told that our school is more 'applied' math, and they stopped teaching combinatorics classes a coup

I'm in the middle of a PC build. I haven't had a regular PC in nearly a decade, so I've had to start with buying monitors, a case, keyboard etc.... I have an R295X2 on the floor right now, I don't have a big enough PSU to use it yet.

I want to be able to play games in Windows on super-high graphics settings, but I also need to do a lot of things in a Linux environment.

If I go with a 6700k setup I'll have to reboot to go between the operating systems. On the other hand, I have a friend running dual Xeons, and he just boots a host system and uses hardware pass-through (VT-d) to run guest OSs. If I do this option, I'd probably run Opterons and I'm not sure that I will get good game perf

I am in a group that is implementing new WiFi protocols for a year long school project. There are a couple WRT54Gs laying around in the lab, but anybody that knows anything about programming them is long gone. What is the lowest level access that I could get to the antennas? Can you see the raw samples coming in from the ADC somehow?

Basically I want to know if I can program on the physical / link layers.
