Someday i'll tell the whole truth of why my videos are so erratic. But for now, i'm still here, still working on them. And i hope to get some more out. I don't know when, but i'm not stopping.
we understand that Mr Gus is very demanding of your services.
yay!
Don't worry, your audience is here for your quality not quantity
I'm glad to hear you're not stopping! Take all the time you need
We know you're a supervillain. It's okay. Evil science is still science!
Just wanted to say that you've inspired me to study chemistry, and pursue a Ph.D. I cannot thank you enough for all the years of education and inspiration you have given me. I will truly always value you and your work.
dont blow yourself up or burn ur lungs
The road is very troubled and tiresome, but it is worth it!
@@MiguelAbd is it?
@@marios1861 i know for the longest time NurdRage was posting jobs on twitter when he was looking for a new job and they were paying ludacrisly low wages and requiring masters and phds
Same! I started watching NR when I was in middle school, now I'm half way through a bachelor's in chemistry.
This channel is one of the reasons I started studying chemistry and I'm so glad you're still active
Me too. When I decided I wanted to try removing metal from broken electronics, it wasn't the multitude of channels focused on that that I went to. It was NR, with his understandable explanations that I opted to lay out a plan from.
Still active? Not posting for almost a year is "active" now huh?
@@Marin3r101 Active now, yes.
Me too, I started with pyrotechnics and advanced my chemistry knowldege to make better quality reagents for pyrotechnics and yeah, now im studying chemistry
@@Marin3r101 For "active" I meant that he's uploading again, I wasn't sure how to word that because it was 3 AM
No way, he's back! I've been following your videos for a while, especially your series on sodium. It's amazing to see that you're still making videos. And on electrochemistry too. I've been wanting to try some electrochemistry myself to make persulphates.
Love the videos. This one should be titled "How a Chemist solves a mechanical problem". In hot environments a simple mechanical wire crimp would have solved your problem or a simple spot weld of the leads. I guess it all comes own to your background,
Chemistry = Chemically bond them
Mechanical = Mechanically bind them together
Electrical = Use high current to fuse them together.
Yeah, I do wonder how well this will hold up. I've never even heard of someone using electroplating as a method of bonding anything. If you can't do resistance welding or crimping, it seems like brazing would be the go-to for an electrical connection.
yeah i would've went with a crimp or some connectors, but that's because i'm lazy and hated doing soldering for stuff like car stereos
@@hawaiianrobot for that crimping is better anyways due to vibration
I think you've got mechanical and electrical flipped
I remember watching this channel a long time ago, thinking about how cool it would be to be able to mix different things together and watch them change color, get hot, or explode. Now here I am well on my way to getting a B.S. in chemistry actually able to understand why those things happen the way they do. I am grateful to this channel, and quite a few others, for introducing me to parts of science where the regular school curriculum could not.
OMG i have been watching your channel since a kid, and now I'm a Chemistry Major !! THANKS YOU
same omg
@@Treebark1313 YASSS, Imagine watching Chem Player, Nile red when his channel still chemistry pure, and said OMG i love this and decide to became a CHEMIST
Dr. N-Butyl Lithium, you're back! So pleased to see you in my notifications again. I hope you can show us more sooner than later, but we will be patient. It doesn't have to be anything grand in scale, just hearing from you is enough.
Yay! You're back! A whole load of us missed you! Whether or not you realized it, you've become someone a lot of us look up to and/or look forward to hearing from. Stay well, we hope to see you again!
IKR! I've been watching his videos since mid-school, know I'm about to finish med school!
Indeed!
Seeing you back was the highlight my day. Of course, I wish you could post more, but you do what you've got to do with your life. I will say that I'm perfectly content with what you probably consider simple stuff. It is always fascinating to see how much you can use electrolysis in place of other methods, and I'd be quite happy to see you just do simple useful (or not useful) electrochemistry, since you're such an expert on it.
As an alternative to the copper plating trick, you could probably just get some small crimps and a cheap crimping tool and do that kind of repair in a minute or two. You can get basic crimp cylinders without insulation, which given that they're really just a short segment of plated copper tube, should hold up quite well in the hot plate. Crimps can be some of the best connections and hold up better than solder to vibration and thermal loads.
Solid copper, not plated.....
@@szsenyuk8887The small ones I get are usually tin-plated as an anti-corrosion measure. Means they're silver rather than red unless scratched, but not much more than that.
Probably wouldn't even need a proper one but a small length of copper tubing and then coat with ceramic paint
@@EdwardTriesToScience I've had much better luck with the purpose-made ones, but it can be done enough to work with small copper tubing. The copper tubing is almost certainly a much thinner wall, and that makes it hard to get a good crush-into-connection on it; from memory, the small sizes of crimp the wall is around the same thickness as the hole diameter. Probably easier to get the crimp than to get a tube with similar specs, unless you Really Need One Now and can drill out a solid rod for it, or can put up with a significantly less reliable connection.
@@EdwardTriesToScience I would suggest ferrules. They are literally under a cent per piece. a ferrule crimper is like 60 bucks but it's a good long term investment because from then on you can make solid connections for practically free
I'm glad to see you're still alive, unfortunately the same can't be said for other channels that disappeared during the past year and a half.
One of my favorite channels for the past 10+ years. Please for the love of science and experiments continue to make videos! The loyals appreciate you more than you know!
When we need him the most he returns, Welcome back Nurd Rage!
I used to watch your videos when i was 8! i loved chemistry then, and its so great to see you still making videos 8 years later!
i cant believe this fossil is STILL ALIVE, nurdrage MADE my childhood in dangerous(for a 9 year old) and fun(for any age) way!!!!! This man blazed the trail for the ENTIRE pop chemistry genre of youtube and is still putting out peak content today. you love to see it.
Missed your videos so much Professor N. Welcome back
I used to watch this as a kid. You are still going strong!
Your 'source of copper' seems an unreasonably expensive alternative source, but I guess you do what you must.
Plating the thermistor onto your hotplate leads is ingenious!
would zinc mess this up if you used gilding grade copper 95/5
So good to hear from you again! This is awesome. I've never would imagine that a slow copper plating would be strong enough to bond wires together. Your videos are fascinating, please keep them coming!
Had to scratch my eyes, I didn't realize you were alive and uploaded, literally been looking for sulfuric acid generation, synchronicity is beatiful
You were one of the first people I subscribed to over a decade ago, and I’m so grateful that you’re still making videos! Thanks for the upload
ermagherd!!! YOURE BACK!! The KING of online video chemistry! The Legend Returns!!
Good to see you're still with us to teach!!
Glad to see you back. Take whatever time you need.
ive watched you from 2013, i watch you even before i know thoisoi or even nilered
Always a positive when NurdRage uploads.
Hey, NR is still with us! Thank you, Mr. Rage, for creating another cool video for us. That is by far the most creative way I've ever seen of attaching wires to a sensor! Cheers M8
So happy to see you are still active and making videos. What a great idea to use electrochemistry for electrical bonding, genius. Thank you so much for sharing your work, I really enjoy your videos.
I'm so happy you're back! I hope you'll make more videos very soon
Welcome back bro.
I used to watch all your videos around 10 or so years ago or so.
Was pleasantly surprised to see you are back 😊
OH MY GOD HE IS BACK!
Im glad you are still alive and kicking!
Very happy to see you back. ☘️☘️
love that you made sulfate and then showed one of the uses
So glad to see you back, NurdRage. We've missed you.
Awesome to see you're back!
So happy that you're still making videos!!
glad your still doing videos i love your stuff this channel inspired me to start up amateur chemistry. And videos like this with practical solutions to problems are amazing.
Great to see you back..loved your videos over the years
Thank you for continuing to make videos. I've been following you on RUclips since you first started. You're the reason I enjoy documenting my hobbies and got interested in chemistry. :)
So glade you are still making these videos ! i got a little nervous when i noticed that last video ticked over to 1 year
Keep'em coming boss. Your the reason i started studying for my degree. Even the simple q&a videos are great.
It always makes me happy to see a new video from nurdrage
It's amazing to see you back!
Thank you, nice to have you back :).. Take care
Here from Red Nile channel he mentioned you this is the first video I have seen from you it is excellent i liked an subscribed .
So, did I just see how to make copper sponge and copper sealant? I am so going to learn this! Thanks for Raging!
Glad to have you back in the lab!
Bonus mode is when you use this to drop precious metals from a mixed metal (copper-dominant) bar, and then collect them as slime off the bottom.
So glad to see another video from you! 😁
One of the greatest channels on YT
This guy was my fav RUclipsr during childhood. I come back every once in a while just for nostalgia, even though I don't understand much
Brilliant way of restoring your hotplate, by 'growing' a copper crystals on those leads, and avoiding solder...
This was my favorite RUclips channel growing up 😩😩😩 I didn’t understand that you were an influencer, but I thank you for your work and you made a huge difference in my life ♥️
Wow, what a great idea electroplating copper to create connection between component leads and wires!
Due to less pollution
Ancient legendary chemist Nurdrage can be seen again.
I am so happy you are back!
So glad to see you back in the lab!
A more efficient solution to producing stronger, less spongy copper when depositing is to use assymmetrical AC. I made alkaline battery rechargers during the 80s with this technique. By using diodes to clamp the voltage over one phase, it's possible to limit the outgoing current that would otherwise pull copper ions off the deposition substrate whilst the unclamped phase deposits them. The resulting copper deposition is much stronger and compact.
Awesome. Glad to see you back.
Welcome back! No worries about when new videos come out; they're always a treat regardless.
This is the channel I've been missing.
Awwww my childhood hero . Always nice to see you upload. Thank you for inspiring me studying chemistry too.
I am glad you are back.
The king is back! Congrats
In an old text describing copper and silver refining they boiled the slime from a copper cell in sulfuric acid to dissolve both copper and silver, then poured it into cold water to precipitate the silver sulfate. The copper sulfate were only diluted and could go back to the copper cell as electrolyte.
If my memory doesn't fail me it was done with concentrated sulfuric acid in cast iron pots, but lab glass should also work. :-)
Thanks for posting again! I've learned so much from your videos and I'm looking forward to your coming ones.
I wonder what other mysteries old text have
NurdRage is the best chemistry youtuber with the initials N.R., hands down!
Yeah? Well, the _other one_ eats his own chemistry.. 🤤
I'm glad that you're back
It's good to see you again!
Thank you for posting a video. It's been so long!!
One of the best of YT.
OMG!!! I'm so happy your back.
Great to see you back.
A nurdrage video is a real treat. Hope you're doing well
Wow, its been nearly a year. Glad to see a post.
Glad to see you back
What a great way to wake up on a dreary Saturday morning. Welcome back.
You know we miss your videos when you have thousands of likes but zero dislikes
Great to see you back man.
Very useful copper plating Current vs Voltage info. Thank you!
Although I've moved over to mechanical engineering instead of chemistry like I intended in the past. I still find your videos fascinating ever since I found your channel back in high school about 10 years ago.
Seeing this video just really brought me back to that time our teacher showed us copper sulfate pentahydrate and how it went from that vivid blue colour to white by just heating it up, then back to this beautiful blue again after adding water. Thank you for this video, thought I'd tell you I've been silently enjoying your videos over the years and look forward to your next uploads. Glad to see you are back.
I'm still here, waiting for NurdRage to drop a new video
Glad you're back
Very happy to see more content!
I learn a lot in this channel, and i use my knowledge for my own porpuses thanks you NR. God bless you.
Welcome back! I'm glad to see you again. :-)
Nice to see you again, sir.
Missing your awsome and professional chem videos for a long time! Welcome back! ❤ from Bangladesh!
Yes!! Finally a NurdRage upload! This made my day.
You're alive! This is great!
Great to see you back! :D
We got it and we can absolutely foresee why. Thank you!
Happy to see you are okay!
hey bro thanks to you i made an exploding rocket when i was 14 and stopped a local marathon, nice to see ur still kicking
OMG, you're back!
Glad to see your videos again NurdRage. I hope you're doing well.
Welcome back, I missed your videos
He's back!!!! after almost a year he's back!!!!
I was actually thinking about electrolytic copper welding recently and how to do it. Good timing!
This just made my month
