I would call it stupid too, but the voices actually advocating for this in the mainstream are all from the left. Every one of the manifestos I read from those 2015 campus protests all called for racially segregated "safe spaces", and at their protests were chanting a quote from the Communist...

On the heels of 4 major universities offering racially segregated living areas, at the request of some students, some people decided that didn't go far enough. http://reason.com/blog/2016/10/26/video-uc-berkeley-protesters-built-a-hum']This[/PLAIN] week at UC Berkley protesters decided to...

Then come up with a plan, look at what grants are available, how much you're making now, and how much you'll probably need. Maybe it will work, maybe not, you'll never know unless you try. Though I must question whether or not going back to school is the best option for you now given your state...

Electrical engineering is about applying electricity to do things and that can range from really high power applications such as power transmission to really low power things like electronics. Mechanical engineering is about mechanical devices. Chemistry is about studying how chemicals work, but...

This isn't a bad idea, I must admit though that CS majors are a dime a dozen from what I've heard, but that's just heresay. However going for something in mechanical engineering would be the most practical option, there's often demand for them and it fits well with your physics degree...

I watched a video about this which showed the event in question and that's not what I saw. First of all the forum was basically a safe space, there was one guy in the audience that challenged the speaker and he was quickly silenced by the panel leader. Secondly there were several people there on...

Some years ago there was a news announcement about a quantum commlink between Beijing and Shanghai, more recently a few weeks ago there was the announcement of the first ever quantum communication satellite. I've done some looking but I haven't found any analysis about whether or not this is...

No, it's not a pushbutton switch, it's a rocker switch. Originally what I had was an SR latch wired directly to power to just make it spin. I'm still ok with it spinning in one direction but I'd like to use the switch to control when it's on and off wirelessly. I was trying to replace the latch...

Thanks for your feedback. What I was attempting to do was replace a nand latch circuitry to remotely control an H Bridge circuit for a small electric motor to get it to turn on and off remotely albiet in just one direction. So I took the switch, wired it to the inputs of one of the gates...

Coyotes. Not really dangerous to people but they are a real threat to pets.

For a hobby project I got a couple of RF modules, a QAM rx2 433 receiver and a DSQAM tx1 transmitter. I understand they need some kind of TTL to work, would just using some NAND gates hooked up to the transmitter and receiver be enough or do I need something more fancy like encoders and decoders?

As others have said PF has a lot of really awesome people.

It doesn't seem that warm, I can't really tell if it's putting off that much heat, surely a good sign. On the other hand I didn't leave it plugged in for that long so maybe there wasn't enough time. Anyway, thanks for the truth table, looking into microcontrollers I think right now I'll go with...

Ok, so I am missing something. I think it might be a stepper, but I'm not totally sure because it doesn't say specifically, just gives a voltage range. So do all 4 channels need to be active or just the two for the side I'm using? Also, any recommendations for a simple micro controller? I...

A few months ago I asked about diodes for a basic low voltage H-Bridge. So I got the parts together. The first thing I did was to build a 5V voltage regulator, getting power from a 9V battery. I managed to build the regulator with no issues, it puts out 5mA and about 5V. I went ahead with the...
