RC planes ARE drones. I think the word you meant to use was 'multirotors'.

I think you've completely missed the point of what university is for. University is to study something you're passionate about at a high level, it isn't neccesstily a gateway to a job. There are plenty of people who study som

My first year accommodation at the University of York was somewhat similar to this, having been built in the 60s from prefabricated concrete panels. I lived in Derwent college, which is some of the cheapest accommodation due to it being in

I imagine this guideline is probably just used as a barrier to apps with no real functionality, to stop people submitting "Hello World" apps and the like.

Hardware for autonomous flight will have to include both GPS and inertial sensors. I suppose an EMP beam could theoretically be used to damage the electronics, but it probably isn't very practical and the electronics could easily be de

Assuming you know the frequency a drone is flying on, it is trivial to jam. However a lot of the more advanced flight control systems (even on hobbyist drones) will have a failsafe that causes it to return to home or similar in the case of

This same thought occurred to me, surely rather than wasting the whole digger, there must be some salvageable parts that can be easily carried or hoisted out of the holes and sold as spares?

Admittedly for $200 you aren't going to be getting anything fancy, but you'll certainly get something that gets the job done. Since this was my first RC project I went with a $23 radio system, which for basic control is fine. You

Although this is interesting, I think DIY multirotors are where the revolution really is. I've built my own and it really isn't that difficult, assuming you're buying a kit for the frame and not manufacturing your own it&#x27

I have to agree with you about the Black Arrow - here in the museum in Liverpool is one of the Black Knight rockets which were the test vehicles the Black Arrow was based on. I think the design of the Black Knight is even more fantastical,

As other people have said, jamming would certainly be illegal because of the potential for interference. However, they could fairly easily implement some kind of passive signal blocking. I know that a few schools, including the one I went t

If the government was willing to pull those kind of tactics to have you killed, I'm pretty sure they could do it without self-driving cars.

Do you realise that almost all the development of early computers was to contribute to the war effort? Usually to get things done, you have to create things that help a subset of mankind in a specific way.

Exactly this, in university one of my professors in first term rather than using slides, printed his slides onto paper and put them under one of these cameras, visualisers as they're called. I found it much more engaging since he could
