DJI Mini 3 Pro - night, mild aurora alert
This was taken on 09/Nov/24, after we’d received an aurorawatch notification. Not sure if we captured any atmospheric effects but there was a clearly visible dim red glow in the sky while filming. A great time to put the drone up and see if we can record anything. A few fireworks captured too.

DJI Mini 3 Pro at night, 02/11/24, fireworks
Просмотров 64Месяц назад
Filming fireworks at night in Manchester on 02/11/24. It’s nearly bonfire night in the UK, and many people are doing their own firework display in their back yard. Makes for some good drone footage. Only got a short flight in, as the batteries only had about 8 mins left on them. Everything will be on charge ready for 05/11!

Don’t add too much water then you won’t get so much water dripping
Anyone need any help please ask me
You can brown the meat in the pressure cooker you don’t need to fry it in frying pan!
no demop of working or moving the angles around.. so more like an unboxing than review
Hello I just bought this dishwasher and would like to install it myself. Any tips on the water connections?
@@ailchat - It’s a standard connector to the cold water, so it’s not too complex as long as you have the relevant pipework already. If not, better to ask someone to help you. Leaks make a right old mess.
Thanks for the easy instructions, i was a bit hesitant to use it at first and couldn't get my head around the instructions. 😊
@@helloitzA - All rice cookers work in a similar way, so you’re set for life now!
DMOJ is the most frustratingly USELESS site ever. My code for a problem works, I've tested it in my own IDE. No indication as to how data is being entered into my functions whatsoever.
Is it effective for oily pots? And does it clean cookers well? Thanks is advance
@@fatimatravels2471 - I suppose that it depends on how dirty and oily the pots are, how good the detergent is and what cycle you use. We use our washer on the eco cycle every day - we wash our wok in there and any other pans we use. I’d say that if a pan is absolutely caked with cooking mess, a quick scrub in the sink with cold water then dump it in the dishwasher usually works for us.
@@daveys Thank you 😊
Good video
How to reach powesupply please
I’ve never needed to reach the power supply on this dishwasher yet, not needed to take it apart so unfortunately I cannot answer your question.
Great info and demo. Does the b8 fuel filter have a water sensor as when I've looked it up, there are two versions? Thanks
Thanks for the compliment! My version of the filter housing didn’t seem to have a water sensor on it. In the case of this car, I’d not had it long and I just bought the filter that the motor factors told me would fit and they were fine. Probably should have shown the filter make/model but I’m learning as I go on these videos. The main thing for me was recording that I’d done the job. I also did an oil change one but it didn’t come out properly so I didn’t upload it.
Despite the better audio, I still sound "northern". Nothing I can do about that...sorry.
aint't nothing bad being nothern, brother! Ty for you content, still moving towards python dev, and doin exercices with you!

The original video is here: ruclips.net/video/V3xb8zmj2HM/видео.htmlsi=XzM45HDIH4RGYxUS
There’s a slightly better way of doing the logic, using string slicing. The video for that is here: ruclips.net/video/y2rl7RaoALg/видео.html
As always, these videos are unedited and unscripted, so you can see the thinking process. This means that there will inevitably be gaps in the audio, dead ends, and mistakes. If you’re OK with that, please consider subscribing!
DAVE!!!! do you have a video of putting the tent up???? that would be awesome. If not, i really cannot find a decent one. I guess I'll make one myself. thanks, let me know please
I don’t have a video of pitching this tent, but there is one somewhere online as I have seen one before. It’s not a huge pain to put up, but from the sound of it, you have one of these tents too…so you’ll already know that.
I have started the book "Learn to code by solving problems".Great book.And great help from the videos you are making.Keep going
Thanks for your kind comments! Solving the problems in real time while discussing it and having not seen the problem before is really difficult, especially when you’ve only been programming for a few months! I do appreciate the words of encouragement :-)
Hard to believe that this is a camping stove and not one that’s designed for a lounge! So relaxing!!
This idea for this video was triggered by two things: 1) My daughter suggested making a Python basics video that she could learn from. 2) I saw comments from someone in another video suggesting that there were a lack of basic Python videos that helped them. I hope this addresses both these requirements.
The old brain just didn’t seem to want to code this afternoon. If this happens to you, go and have a break!
Hi, thanks for the video I just bought pressure cooker from tower and was not able to cook it. Your video helped me a lot.
You’re welcome, glad my video helped! I found that ours recently wouldn’t reach pressure. I cleaned the pressure valve and everything worked again. I also found that the relief valve came loose and needed hand tightening over time. Main thing if you’re new to the whole thing is to be aware of how long it can take to get a few litres of food to boil and then up to pressure if you have a weak hotplate. Once you know what it’s supposed to sound like, it’s a lot easier to use.
If you’re wondering how I’m getting on, have a look at some of my more recent videos. You can see me solve a dmoj.ca problem using two different methods: strings and lists.
Thanks
You’re welcome!
Holly cow! This might be book I’ve been looking for! I fell into the exact same problem that you had! I will head to the book store - give it a go!
I did the majority of the book, but since have been doing 3 and 5 point problems on dmoj.ca as skill builders. I found the book to be a great help throughout. I could probably give a list of problems that I tackled at some point. I am also tempted to do some coding “live” on RUclips, by which I think I mean tackling an unseen problem, no editing, start to end and talking through it as I go. It’ll not be pretty, because it’ll have some dead ends and mistakes, etc but it’ll show just how the process works. I nearly got the courage to do one today but I couldn’t find something that I was confident that I could solve within reasonable timescales. I’ll have a look again tomorrow.
@@daveys Just picked up book! I have to have a physical copy LOL! I actually messed up my first problem LOL! For the output of: ‘’ * 3. I know a little Python… knew the outcome… but chose wrong answer LOL! I’ve had a hard time, bolting my brain to one language - which has really made learning programming a horrible experience. I’ve been advised some guru techs and now staying on Python. Get the nuts and bolts down! Al Sweigart’s books have also been helpful. Knowing I’m tired tonight - I’m going to spend the whole day - from morning til mid-afternoon in this new book. I’ve passed this book 100 times in Barns and Nobles LOL! I’ll check out your live stream! Your book review was excellent!!!
@@daveys Got Concept Check on pg 14 correct. I don’t feel worthless now LOL! Just tired. I’m really looking forward reading rest of this book. I will say, Python at first was tricky due to space blocks! Took me a bit to get my head wrapped around that one. I spaces now… but it was an odd one
@@UnderArea51 - At some times I felt as though the book was a little overwhelming, but stick with it. The curated end of chapter challenges were the thing that helped me most, so don’t miss those!
@@UnderArea51 - Every problem you solve is a step to becoming proficient in writing Python! I still don’t know everything by any stretch of the imagination, but I’m getting better every day. DMOJ is quite counter intuitive if you’ve done any of the other books, because in real life you’d be more concerned about how you prompt the user, but these problems are more about solving specific problems. Daniel has done another book about algorithms, and I have that but unfortunately it’s written in C, so the code isn’t much help unless I put it into ChatGPT and ask it to rewrite in Python. The way he describes the algorithms is pretty good though. Most of the DMOJ problems are actually just wording about 20-30 algorithms in different ways.
Great illustrations 🤍🤍
This pressure cooker is too slow not good
Works fine for us. In what way do you find it too slow?
is this book for total beginner?
@jaybala - It teaches from the ground up, so I would say “yes”. This book really helped me gain some traction learning Python because it introduces the problems in a curated way - related to the subject you’re working on. I won’t say that I haven’t referred to other books, or other sources at all, but this is certainly a great framework for getting started.
Thank you
Son una mierda , a los 3 años ya estan dando problemas , en 3 años se me a picado manguito y perforado la bandeja , OBSOLESCENCIA PROGRAMADA MADE IN CHINA.
ok merci beaucoup pour votre aide je vais regarder cordialement
Merci pour votre réponse c’est les pignons pour l’avance automatique et le filetage j ‘ ai cassé deux pignons le 63 dents et le 32 dents je voudrais les remplacer merci cordialement
I’m not a seller of these things, I just own one of these lathes and made a few videos of mods etc. Try that Clarke International site, hopefully they’ll be able to sell you single gears. If not, I’d have a look at these other lathes: Clarke CL430 Is same as: Sealey SM27 Warco WMT300 (although this is more advanced than the CL430) Smithy CB1220xl or also Midas
bonjour monsieur sauriez vous si des pignons sont disponibles pour ce tour ? j'ai cassé les miens merci cordialement
When you say sprockets, which part of the lathe are you referring to? I’m not sure what spares are available for this model, but you might want to contact Clarke International at this URL: www.clarkeinternational.com/service-and-support/
Cheers for this, Dave. Never thought of that.... Also, any idea how to take out the 3 jaw chuck back plate out? The manual and explosion diagrams don't explain at all and I'm stumped!!.
I haven’t removed my backplate, so unfortunately I can’t advise. When I fitted my 4-jaw chuck, I just made an intermediate adapter plate.
@@daveys Yep, turns out the backplate and spindle are one piece. Looks like adaptor plates for me too :) Cheers.
@@DaveHuk01 - I just got a lump of metal, mounted it and turned it to the right side and it worked pretty well. The main issue with this lathe is the lack of easily selectable variable speeds. I needed slower speeds at the outside edge than in the middle (obvs). I could see where the optimum speed was as I passed through that diameter. The surface finish would change from mediocre to really nice then go back to mediocre.
@@DaveHuk01 - Let me know if you need to know which 4-jaw I have.
@@daveys I'm fortunate as I work for a Biomass engineering company, complete with industrial lathe and very skilled operator who has kindly offered to make me an adaptor. I still can't understand why Clarke opted for this configuration. Even my old lumberjack woodworking lathe had a simple screw on configuration. I've a lot to learn but, I'll get there. Especially watching video's like yours my friend. :)
I’ve been doing 3pt questions from DMOJ.ca all day today. Great practice!
This is in prep for me to do live Python on RUclips. There is no audio included, because it’s too noisy in here just now. The intention is perhaps to attempt some of the DMOJ problems in real time.
One thing that is critical to these saws, is to set them up correctly. Essentially that means aligning the blade so that it doesn’t fall off and that the vice and blade are square to the saw frame. Once done, it’ll work superbly.
These books look really good Dave! Something you might enjoy are some Of the old engineering videos on RUclips. One in particular, ‘spinning levers - how a transmission works’ really made clear how gears work to me. These videos are 30s or 40s, black and white, but in some senses quite cinematic. Some of the ways of explaining things used in this era do seem to be so clear, I agree.
Thanks Matt, I’ll have a look at that.
I’ve just completed one of the problems at the end of Chapter 5 (Ref: Preokret) and it is honestly one of the most frustrating things to solve, but once I figured it out, it wasn’t all that hard. I suppose that’s like any skill really - easy once you know how.
This looks like a superimposed image, but I can assure you that it is 100% genuine. Absolute rip roaring fire!
On dmoj.ca, try “Sorting” and “Misspelling” as starter problems. Both these problems give a good idea of how the code challenge problems work. The way that I approach these problems is that I try to work out the logic steps that the problem needs, then I complete each step one at a time. My code is quite inefficient, but remember that my goal is to write code that works, and is understandable when I look back on it sometime in the future.
Been struggling with python for a 6 month. It is my dream to become a dev, but honestly sometimes i just feel i need to give up. Your video gave me second wind. Already ordered book. So the war continues! Ty Dave, i needed that. Wish you best!
I wish you all the best with your efforts and I hope this book helps! Have a look at dmoj.ca while you wait for the book to arrive. Most of the early challenges are from dmoj. I did a few challenges today and I feel like I’m really progressing. I hope you achieve the same.
@@daveys already on it. It’s odd I didn’t even hear about it!
@@br4vetrave1er - I’d never heard of the online code judges either. They are great. The book mentions 4 of these sites but so far I’ve only seen examples from dmoj.ca used in the book.
I felt like I had to learn a lot more in python and this was a great shout. Thank you
If you already know Python, then maybe just start working on the 3 point code challenges at dmoj.ca and go from there. The book is great though as it curates the problems into an order that doesn’t overload you too much. I do admit that every one of the problems has given me a WTF moment when I first read them.
I’m doing about 1-4 problems a day from DMOJ.ca curated from the book. I feel as though I’m making great progress with coding this time. I’ve not heard anyone comment yet “why bother, because ChatGPT” but my experience with ChatGPT and coding is that it’s great to a point then it suddenly loses context and messes everything up.
Really proud of you! Its so hard to find honest peaople only this bragging and Im getting more and more depressed.
Thanks!! I openly admit to not being able to grasp coding easily. It still feels like pushing custard uphill with a rake but I’m progressing!
Thank you sir
You’re welcome! I’m currently at the end of Chapter 4 and still not great at coding, but I can do loops and variables now without needing to refer to a book, which is bang on target for this point in the book.
@@daveys I'm considering buying the book so that I can get used to the problem solving patterns within these problems more than coding itself. If you'd like to sir. I remember at my first coding year at uni I took python essentials 1 and 2 at skills for all by cisco.(free online) I'd recommend it if it's your first Programming language. Also there is this RUclips channel called engineering drive. To be honest I haven't watched his python playlist but I've watched some of his other stuff while at Uni and ngl he explains things simply and provides material free on his blog.
@@orcaboorish - Thanks for the heads up. The more that I think about it, this book teaches like an actual taught course. I’m getting on well with it.
Thanks bro, these books are great supplements
If I was buying Python books again from the start, I’d buy the Learn to code by solving problems first. Someone recommended “Fluent Python” to me yesterday. I might have a look at that, maybe I can get a sample chapter. I also have a copy of Python Crash Course, which looks good too but I have not really looked at that much yet. Daniel Zingaro’s book is worthy of working through before I divert any further.
@@daveys I’m on chapter 3 now of learn to code by problem solving since watching your video. I agree that it is worth going through. Good thing I found your video lol.
@@IAMTheDeffence - That’s pretty rapid! Memory is built by repetition over time, so do make sure that you keep practicing. I found that the end chapter exercises took me a while to complete but I learned so much from them.
Thank you sir, all the best from nishanth india
All the best to you too! I hope you found the video useful :-)
Yes i bought the book after your review, Kindle format. Thanks again
That was an interesting review. I've looked at buying this model. I'm not sure I want it with no pre-rinse though.
Thanks Tony!! Regarding the lack of pre-rinse, It depends if you can fill a whole dishwasher in one go. We fill ours once a day, so there’s rarely more than a few hours with dirty items in it. Not had any problems with it being smelly or failing to clean things.
