Great model.
This is also a biohazard because they were in peoples mouths.
Just use gloves it's fine. Once the batteries are out you don't have to worry, they are sealed off.
@@Boris_Woodwards Lol my GF 3years into chemo. These vapes could be as dangerous to her as mishandled lithium. Its a hazard worth highlighting.
Are you allowed to take the fallen trees and use them as firewood? I mean that's primo firewood right there!
unfortunately not
disable fwupd bro
Triumphant!
can you make one out of old vape batteries and show how to do it safe? lots of people have done it but no tutorials
@MaskedMageYT yeah ill do that this week. Not necessarily as big, as I don't know how many vape batteries I can get.
Just made a tutorial
Oh mate, when did you start this? I would've supported where I could!
The gee wiz is the most scary car, as your face formed part of the crumple zone in an accident 🚙
@mxfool1508 it is I drove one which prompted this video. Also the suspension makes bumps worse than rigid.
Amazing video, can see the dedication with the shots that you clearly had to set up and then go back for the cameras, in those mountains had to be quite a workout!
Great job standing up for your morals!
Adorable ❤❤❤
By far my favourite thing you have done
Pls don’t steal the moon
It's gonna explode soon
My credit card company will issue me a refund on any product that arrives broken if the manufacturer or seller will not replace it. Amazon prime will do the same in the USA. Not sure how this works in other countries.
@chuck_howard yeah I did that got my money back but it kind of sucks that it came to that
Don't worry, no one fell for your sold out peddling of junk anyway.
I suggest you get a microphone to clip to your shirt.
@chrisbailey5055 I have one I just didn't turn the volume up enough. Apparently.
Chineseium company not being up to snuff? Shocking.
Audio, man...
Stand by your morals mate.. broke is broke and if they warranty it but won't warranty it.. no more .. I won't work with them either
Yeah, Its sad, I had so much hope for the company as well
Make sure you get a charge back from your bank. You have the right to receive a refund on any defective or broken item within 14 days of purchase.
Already done, I did that as soon as there was a problem
If you are using one or 2 cells and need 12V you are using a Boost converter (not a buck)! Also please do not wrap the BT receiver in Aluminum. For everybody else i would recommend something like a Qudelix 5K. I know it is a lot more expensive but it provides crystal clear sound and above all a really nice App with sooooo many features (and they improove the App constantly).
Yes you are correct I am using a boost transformer, the alluminium has very little effect of the range of the bluetooth connection.
Youre a very good boy! 🤗
Thanks
Ok so the solution to forgotten earbuds on a hike is ordering parts from china that will arrive sometime next month. Got it!
Like I said, I'm not a rational person
cool video man, i did a similar thing by adding Bluetooth to an old cassette Walkman. i added transmit (connect to BT speaker or headphones) and Bluetooth receive (to send BT music from my laptop or phone to the cassette Walkman to record my own mix tapes) i live adding Bluetooth to things that are too old to have had it.
Nice man
Love the Faraday cage case!!! How did you use a 1s bms but have two 🔋🔋 ??? What kind of wire did you use that you can break by hand and strip by hand?
They are in parallel so it's a 1s2p battery
Awg20.
Buddy you can buy a Bluetooth adapter for that same price and it won’t look like an IED. We’ve solved this one already
For a bluetooth 5 one like this it's about 30aud where as this costs about 8. But equally it's fun to build projects
Yeah and you can buy a car off the lot but some people like building them.
That's why you're commenting on UA-cam videos taking a backseat to real life instead of living it and gaining hands-on experience
Super cool, I wish i got a notification for it though
We own 3d printers
Not all of you, I did a poll, and only 25% of my tiktok followers own one

What is going on who r u and what are you predicting on this video 😅
@MAHDERTsegay-p4i I'm tending on tiktok, because of a meme, where people say I predicted everything.
Did you predict it😂
Yes that's why I made this video
Mna HE PRWDICT IT. i subbed.
you predicted everything
Good luck the man who predicts everything. Keep going lol🥰
6:43 so, a couple things: usually a MOSFET's gate threshold voltage is pretty low, it'll start turning on (just barely, meaning a high drain-source resistance) with just a couple volts, and then the drain-source resistance approaches its minimum at maybe 10 or 12 Vgs. You really need to read the datasheet of a MOSFET to have any idea what a given gate-source voltage will do. also: ideal MOSFETs don't automatically turn off when you disconnect the gate (see the end of the comment for why real MOSFETs sometimes do anyways, and why this shouldn't be relied on). the problem is, a MOSFET gate is basically a voltage sensor, it's a small capacitor that detects its level of charge and turns the switch on and off. When put your hand on a Van De Graaf generator and your hair stands up, it doesn't immediately flop down when you let go, because you are still charged; you have to touch something grounded, causing a spark of current equalizing your voltage with the voltage of ground. similarly, an ideal MOSFET gate doesn't consume the charge in any way, it just sits there, the mere presence of a charge difference between the gate and the source passively activates the switch. so when you disconnect the drain from the voltage supply, it'll keep chilling there. This is great for efficiency, it means that you don't need to consume any power to keep the MOSFET turned on, you put in a small amount of energy to *turn* it on and then it'll just stay on, modern computers would not extremely inefficient without this advantage. in your application, where you just want a simple circuit to make a switch turn on and off, this doesn't matter and is just an annoying problem you have to solve. The solution is to connect a resistor between the gate and the source, something in the 1k-10k range probably. That way the gate-source capacitance is constantly being discharged, and requires a constant stream of current to keep it topped up, so if you cut off the power it'll discharge at a predictable rate and quickly drop below the threshold voltage, turning it off. You can check the datasheet for the gate capacitance and gate threshold you can calculate how long it'll take to turn off for a given voltage and resistance, but practically for your use case 10k should turn it off plenty fast enough while only wasting a negligible amount of power (as per ohm's law, at 12V a 10k resistor draw 1.2mA of current, 1.2mA * 12V = 14.4mW). This is often called a pull-down resistor, because it's "pulling" the gate-source voltage towards zero. when you connect the gate to a voltage supply, it's a much stronger connection so it "wins", "pulling" the voltage up to 12. when you disconnect it, the pull-down resistor "wins" by default. In practice, nothing is a perfect insulator, so the imperfect insulation between the gate and source of a MOSFET can be thought of as a "built-in resistor" between the gate and the source. However, this is an undesirable property, and manufacturers are always trying to maximize this resistance. the only spec for gate-source resistance you'll find in a datasheet, if any, is a *minimum* value, so if you make something that relies on it being at most a particular value, it's either not gonna work, or be up to the silicon lottery, random environmental factors, the electricity gods, etc. essentially, a real-life MOSFET will turn itself off when the gate is disconnected, but you can only calculate the *minimum* amount of time it'll take, in practice you never know if it'll take 100us, or 3 seconds, or 3 hours. and if it does take 3 seconds, it's gonna spend a lot of time in the in-between ("linear") region, where it's switched on but its drain-source resistance is pretty high, causing a large share of the power of the circuit to dissipate in the MOSFET, and it'll blow up. if you don't like this weirdness about charge and voltage, you can use bipolar transistors, their "gate" (they use different terms, the "base", "emitter", and "collector" of a BJT roughly map to the "gate", "drain", and "source" of a MOSFET) is a *current* sensor rather than a voltage sensor. they're very different devices and not as well suited to this application, but for a simple device like this with relatively low performance needs, you can basically pick whichever type of transistor you find the math easier for.
oh. reaching the end of the video, you did use a BJT? i think you missed that change in your narration, because where you last left off you were using a depletion-mode MOSFET?
also, since you didn't mention datasheets at all, and idk what caused all the MOSFETs you got to not work, i should also mention that the pinout of transistors is not standardized, you have to check the datasheet for the specific model. for most packages I'm aware of, i don't think there's even a de-facto default most transistors will use, so you really can't get away with assuming the pinout. I would expect some aliexpress transistors could be totally non-functional, but the majority of the "non-legit" transistors you get will be counterfeits. counterfeit components usually try to fly under the radar, they don't want them to be obviously fake at first glance which means they need to work and not instantly blow up. the ideal counterfeit component is one that doesn't cause any problems at all, and the next best thing is one that doesn't fail until it's too late to reject the batch. most counterfeit parts are either salvaged parts that have been cleaned up and sold as new (very problematic for electrolytic capacitors which wear out over time, while semiconductors theoretically might still work fine), or a cheaper part (or even a clone) that has the same basic function, package, and pinout, that has had its markings changed to make it look like a more expensive part. that's why i'm suggesting possible circuit issues, it seems weird that all the MOSFETs you got were fully non-functional (unless you bought them all from the same seller)
I used a depletion mode mosfet
The issue with the mosfets was Purley that they wre from aliexpress, I have actually since recreated the project with new mosfets and everything is working fine. I just had mosfets that didn't match the data sheet. All the mosfets were same pack, I nought it specifically for this project.
@@Boris_Woodwards ok, that's good. i'd still recommend adding a resistor to discharge the gate for long-term reliability though
Look up those MAX745 lithium charge modules! You can connect one directly to 20V and it steps the voltage down to 1-4S for your battery, has an adjustable charge current. Much easier and efficient that way. Also, with the heatsink inside and without fan it will definitely overheat the leds very quickly.
the IC supports this, the question is whether the board does. the input capacitors also need to be rated for that voltage, and since it's a buck convertor, a larger voltage drop means more ripple current for a given inductor value, so it affects the calculations for the inductor and output capacitor as well. the chip is only part of the picture
@@spambot7110 It does obviously. Also it basically needs to, since 4S is 16.8V that means you need to supply ≥18.8V for it to work at all.
The supplier that these boards come from has 20v modules, but this project was rather time rushed, and as I live remote it would be hard to get them in time
From tik tok
lol you should get a aliexpress sponsership
Would be pretty nice
The predictions are unreal 🙌🙌🙌🙌🙌🙌🙌🙌

Absolutely killer video. Thanks, I’ve been wanting to try my hand at this and you’ve helped me a ton.
Great video, thanks. Inverter and charger ordered! Can you recommend a BMS product for this project please?
Depends very much on your location, what country are you in?
@@Boris_Woodwards Sorry, of course. I'm in England.
My favourite is this one: www.cellsupply.co.uk/bms/daly-3s-12v-30a-bms the issue being that you cant get them without paying for a larger order. this one off amazon(www.amazon.co.uk/Ouitble-Lithium-Battery-Protection-Charging/dp/B09XV8RQKK?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&psc=1&smid=A2HD2RU644B7TL) is a good cheap alternative but it has no short circuit protection so I would recommend using another form of over current protection. another good option is to step up to 4s so that the current is lower, in which case both theses options come in a 4s config as well
