Youtube hearted comments of Tim Murphy (@timmurphy5541).

  1. Thank you! I think I can watch this with my daughter and she will a) understand much of it b) see that she too could be an engineer.

  2. I think the most interesting aspect is the use of Boxer. These are about 4-5 million euros each, I think. If this is not too much then we might see an explosion of incredible boxer modules that we wouldn't have imagined being possible until we saw this one.

  3. The danger here is that the Jazz is extremely reliable, enjoyable to be inside, conveniently small on the outside and huge on the inside. German cars are not reliable by comparison. To compete, manufacturers have to push their cars as status symbols....but the new status symbol is a Tesla.....

  4. A person I knew at school apparently became a major and I've always worried about the quality of the Army since I heard that. Hopefully nobody who knows me and him will read this. He was a person who liked being part of an institution and since our school (in Africa) was quite different from the easygoing UK ones I think he liked the idea of being in another place where someone would tell him what to do and what to think. He was inclined to boss people around without the authority to do so and wasn't all that bright about it either. It struck me that if he is typical then the Army isn't a place where one can get away from boneheads and exercise one's brain to the best of one's ability.

  5. I keep wondering about heat pumps (in the UK) and whether there's a way to feed them waste heat of any kind so that they operate in their most efficient mode - so I'm really wondering if a system like this could be plugged into an air-source heat pump to any benefit in a colder climate.

  6. I'm typing this on an RPi 5. I absolutely love it. As an upgrade from the 4 it is great. I have quite a few other Pis and it is already convenient that I can plug cameras and other devices from one into the other and compile the same code without issues on all of them. I have a fairly powerful desktop so I'm not trying to use the Pi for everything. It's primarily my daughter's computer. Witha really nice keyboard and a decent monitor it is a joy to use.

  7. People talk about blockchain a lot but it's not easy to understand how it delivers and what precisely it offers. I think it's rather a black box which we don't question a lot because it's "cool". At some point human effort is required - all the cryptography does is ensure that records aren't changed and that they were created by known people. It doesn't prove that those people are honest.

  8. The only thing that the PI really lacks for me is the ability to play youtube acceptably. It doesn't have to get better in any other dimension to make a desktop replacement for me.

  9. Nice pictures of the car in Cape Town there on the N1 :-) Can't imagine too many people will own one there though.

  10. Love this. İt's a perfect introduction to the kinds of things one imagines doing with a Pico. I did a show and tell video last week at work about the Pico but I should just have played this :)

  11. Short summary of what I've read: It's small because it needs to fit into ships hangars and it's small enough that some ships can host 2 and always have 1 in the air. Small size is not what the army wants obviously and the Army is the loser here - the Navy couldn't buy enough to justify the purchase on its' own so the Army was forced into accepting something it didn't really want. It apparently has only 1 pilot which some people complain about - too small to have much redundancy. One reason why some ships seem under armed but aren't is that they have a helicopter which is a potent weapon. The Merlin is perhaps a more fearsome sub hunter with extremely long range but ships can usually only host one. The component count has drastically reduced through the use of large composite structures that are made in 1 piece. I read that there have been troubles with it and yet what aircraft has no troubles at the beginning? What were they? Have they been solved? I couldn't find any information. Is it now in a period of stability ?? No idea.

  12. I love your videos. Always interesting and realistic.

  15. This is very helpful - especially the bit about getting as many resources as possible. I found this at university - it was the 10th book on partial differential equations that explained the application to a a sphere in a way that I could understand and up to that point I had felt hopeless. Everyone else in the class who passed must have found the prescribed textbook good enough but it didn't work for me.

  16. Congratulations on the excellent new studio :-).

  17. I always found that the problem with people that were 'better than me' is that they didn't have problems with the stuff that confused me. So it was great that it was no problem for them but that simply made me feel more hopeless - that I was just not up to scratch. There's a meme about Einstein having problems with maths when he was young and I think that it's popular because of the way it gives people hope for themselves - even if it's not particularly true. The issue is how to deal with failure to understand and the way that feeling makes people want to never pick up a maths book again.

  18. I believe that Lockheed initially won the contract by proposing that they could upgrade the turrets as against BAE's offer to make new ones......then it turned out that they had to replace them anyhow. I read that the next problem was that the cannon used to need a new barrel after 700 rounds (that might have changed as that news is a bit old). The last problem that I read of is that they can't cheaply convert all the hulls since some are not in as good condition. So as usual....the cheap offer wins by not being realistic and then one pays more anyhow.

  19. Would be interesting if they got excess electricity - what would they do with it?

  20. You're an adventurer. It's boring to stay at home.
