What is the program you are used in end?

i think you are using iron tips for your soldering iron you should try copper one

It is nice that someone actually tried to build this even tho already build ones cost 5-10$, and my idea was to make something similar but i used actual smart watch screen and micro-controller but the attempt was unsuccessful. The idea was for me to incorporate such smart thermos into my diet and water intake up that i will begin building soon. I have already started to make a smart digital scale and addition like this would be perfect but the only thing you need is the distance or ultrasonic sensor that will measure how much % of the water is drank and to have a logic to calculate total liters of water filled and emptied (drank) in a day so i don't count it manually like i do with each glass now. If someone will try to do this make sure it will be water sealed because the water can damage the board or battery acid can get inside.

How about a timer function? Would be a nice thing to be reminded to remove the tea bags...

Good, the bottle option was very interesting, you could think about using it for the gym with counting and resting functions, type of training... and an important function would be to vibrate the phone when you are away from the bottle, this would be interesting so we don't lose it anymore at the gym!

Cool stuff! You could add a small distance sensor under the cap to measure the distance from the liquid and tell you an esteem of how much is left.

Nice project! You probably already know, but there are plenty of mass manufactured smart mugs and water bottles already on the market. I'm only bringing it up because I work in eWaste and they are frequently recycled, I don't think people ever find them as useful as they think they will when they purchase them. As a result I always end up seeing them as one of the wasteful tech products, something that for most consumers is sadly destined to go straight to the garbage. Not to put a damper on the work you did here, just wanted to share my experience with the product category. I'm excited to see what else you build in the future.

⚠Please always check if the battery can leak inside the bottle, battery poisoning has been reported in smart bottles ⚠

Peltier module does what you're looking for but both heating and cooling drinks require extraordinary amounts of energy, add to that the inefficiency of Peltier modules plus the need to vent the other side, that makes it a very very challenging project. Heating could be done with a simple heating element though. Probably like the ones also used in 3d printers.

Hi❤

can they just create codes or can they actually can programm itself?

My dream would be to have 24 of these for each bus seat and mobile software to send childs name to their designated seat. Switching from am to pm and elem to highschool would be so cool just a dream of course.

we have them at work, we use a extra tool to activate them... i was wondering if there is a esp inside....

can't wait for my walmart to start these and let me play doom on the clock

Mehr Knorrrrrr!

Legend. Thanks!

"Văraiables" Not sure if you're trolling me or you're so self-taught it's cute. <3

Found two for Nine…I think they Are still worth, looking on the Overall Quality

6:48 just received 5 of bluetooth devices almost as yours, the back is totaly devoid of any connecting pad... Empty, just a stupid QR code.

Any way to mess with them without tearing them apart?

Great video! How do I install full HAOS on mac mini instead of virtual option?

I will never understand how they can create an fully working display with microcontroller for under a dollar and still make a profit...

You dont actually need to take it apart. You can flash custom firmware into these ota via ble

I have no understanding of why anyone would want soldier as a hobby, to get tools that actually work is expensive, to actually soldier takes training and a lot of practice, it's something the crap from Amazon or Aliexpress is not going to work and the videos on KZbin only scratch the surface of how to do it. I know, I have over 20 years as a Certified Master Electronics Technician.

Boss, your soldering skills are really bad! Your attempt to take out an SMD capacitor with a dry iron bit is proof. For desoldering smd components it is best to add a little solder to both the terminals of the component, and then heat them together.

What language is this meant to be?

I would always look for locally produced tweezers and scissors etc. the ones from aliexpress are not as good. Even the very hard metal ones, they don't have any teeth and the points are weak. Compared to ones I recycled from the NHS in the UK, which have stronger heads but most importantly they have teeth, and grip everything very well. Thanks for sharing your experiences. I am also starting out, and it does get very expensive very quick. Tomorrow my hot air station arrives, I'll be practicing taking stuff off and putting it back haha

my two cents: look for Vetus tweezers

did you recomend it?

I have had a Weller station for over 30 years and still going strong. Industry standard cannot be beaten !

Any mains powered iron is an instant no no. There are plenty of PSU powered irons on the market, don't buy cheap, you get what you get !

if you need to use a microscope you shouldnt be using a barggain bin iron.

Hello, Thanks for your video, it's quite usefull !!! Do you know how to get grey scale for the images? because now we just get "Black" or "white" pixel, but not the grey ones.... So i can see my images... and i know that this screen can display grey images... Thanks for your help

i usually use scissors ( intercable f1) cheap wirestrippers dontstrip welll or dont last long. still looking for a good one.

I grew up as a kid having to use those $10 radioshack firesticks, hated them but its all we had, was happy being allowed to have a soldering iron in my childhood. If you can learn to solder on one of those awful things, you'll find you're an expert once you get to use a nice soldering station.

Great video man, Not many people make "what not to buy" videos. one of the reasosn is, KZbinrs in general make a positive video about a product because they are sponsored, they get nothing out of making not to buy videos, if anything they will stay away, not to be know as a person that gives honest negative view. with irons ive had so many but the best yet has been the Yihua 8786, which is one of the cheapest online. if anyone wants to et an iron is, they need to get one with temp control and display. The second thing is the tips. If i get the tips from the Yihua, and put it on the weller that is performing likecrap. due to the quality of the tip, even on a bad iron, its able to solder. some expensive irons, regardless of what the temp is, the material of the tip, doesnt allow it to be cleaned and tinned properly. My suggestion to make soldering more enjoyable is, More lead, dont be afraid, go nuts on the lead. Its our friend :) I know so many people saying Lead might be bad, while they have cigarettes' in the mouth and holding a vodka in one hand :)

I bought the same phone. Ended up with same problem. Warranty rejected. My advice to anyone who want to buy this junk. Pay to think twice.

Lead rhymes with wed, not weed.

I probably wouldn't use solder paste for anything but reflow soldering with a stencil and an oven / hot plate. For rework it's a lot easier to clean the pads, add new solder with an iron, and then squirt some flux down. That will hold your component while the air melts the solder and the component sticks into place. No need to worry about internal bridging that you can't see and you're much more likely to get a solid connection with the right amount of solder.

As tweezers go, i have a mechanic AAX-17 that i really like. I don't know how other people use tweezers but i do not think i will ever bend these with normal use in electronics. Also they have that ''z'' shape that for me at least is very useful.

If you are looking for high quality tweezers - get a set from Wiha.

This. I have several burnt soldering irons. Too cold then extremely hot.

So pissed off with Samsung over this. 😤 paid almost 2k when the fold 4 came out not even a month later i get that black line starting down my screen, they told me to send it in to see if it was my fault or theirs and they had the nerve to deny my screen replacement because i had a scratch on my camera lens protector(which I added, had nothing to do with the phone ) like are you Freakin kidding me😡😡 that tiny line i had going down ended up blacking out my whole screen and its been issueless ever since for like 3 years now. Shits too expensive to repair still good lord

nice easy to understand

I can confidently recommend Antex Soldering Irons for an absolute solid basics iron. Designed for schools the are _robust,_ i used these at school 30 years ago. They also make stations target than just irons. Inexpensive and bullet proof, heats up quite quickly and has a burn proof silicon cable.

If serious about repairing stuff Get quality branded kit a minimum Multi meter Solder station Hot air station Various flux types Linear variable PSU Quality bench light Optical microscope is a requirement if dealing with the micro world & numerous other gear that help with this hobby / profession. I use a metcal solder station which is crazy priced new but quality kit can be found on the second hand market.

I have 7" LCD version of a microscope you had shown as bad. In my opinion, you're both right and wrong. if you intend to use it out of the box, it is bad. But if you buy steady arm for it (like for microphone), you'll be able to use it at the angle, and your usable workplace is actually unlimited. You may place it as close to the soldered stuff as like and magnification is no longer an issue. I'd actually recommend to buy steady long arm for any microscope.

I recommend cross jaw tweezers

The best tweezers I have come from the hospital, they have 'single use' tools, the quality is really good and they were free. Yes I have cleaned them very well!!

for thick wire the fully automatic stripper works well(the one that look like a bird) for thin wire they just break the wire, you either need to use a traditional one with multiple hole or just one hole but you can vary the size of the hole, the one hole one obviousely require more practive to use otherwise you cut the strands inside too but it is the one i use now over the one with multiple hole
