If it is the only problem, just download ansi.h header file from a github and include it into the project. ansi.h is a universal file so probably any should do the job

@@michaelwittmann3176 You are welcome, my friend :)

Capacity of a battery has nothing to do with a power it can deliver. Some li-ion batteries can deliver 1C current, which is 1Capacity (for the 550mah it would be 550mA current) and some can deliver up to 10C and way more for a short time. It depends how battery was designed. Speaking about the power. So we are talking about 3.3-4.2 Volts from a battery across a load of 2 Ohms. Current would be around 1.65-2.1 Amps, which gives power output of current^2*Load = 2.1Amps*2.1Amps*2Ohms = 8.82 Watts!! So that is the highest power that such a battery can deliver to the load of 2Ohms (if there is no other circuitry that boosts battery voltage to a higher level. Usually there are not). And almost 9 Watts is a CRAZY amount of power. If there is a current controller in the device, which directly controls the current through the coil, limiting it, current should be of any value and power and heat generated by a coil can be controlled. But yeah, definetely 1 battery can deliver enough. Hope this answears your question

Totally agree with you :)

Thanks :) Tried my best, hehe

😅Thanks. Didn`t know that :)

@@NickElectronics Really? Anyway, good job editing it so quickly!

Thanks, appreciate your feedback :) Have a nice day

Feel your pain. That is the problem of all application specific integrated circuits. They do work very well in the applications they were designed for. But it is somehow difficult to use them in other applications🥲

I used FEMM 4.2 software. It is free and quite simple

Greetings from Poland too. Good that the video have helped you :) Have a good day 😀

Hello, in this taser only option would be to reduce gap between metal contacts.

To make assembling more fun and always cut wire with a right color) But for real, cause my non regulated power supply had a current limit and coil resistance was too low to stay below the min current level. So power supply current protection was turning off the power supply. Thus, I had to put limiting resistors)))

@@NickElectronics i thought you wouldn't reply 😅😛

@@justanormal16yearoldkid51 😳

Because of the resistance of the wire ?

Thanks :)

If you have 10V DC + 1mV AC, then capacitor will charge up to 10V and voltage fluctuation at it is goind to be those 1mV. Current still will be flowing in 2 directions, caused by that 1mV AC signal. For example to get from 10V to 10V +1mV capacitor has to be charged, so current has to flow in one durection, but for it to go from 10 V to 10 V - 1mV, it has to be discharged, which means current has to flow "out of it". Good luck)

@@NickElectronics OH, YES. I SEE NOW PERFECTLY. BUT WHAT IF YOU HAVE A NPN COMMON EMITTER AMPLIFIER CONFIGURATION WITH EMITTER RESISTOR AND EMITTER BYPASS CAPACITOR. NOW, ENTER AMPLIFIER CURRENT ONLY FLOWS ONE WAY THROUGH THE TRANSISTOR. AND IT'S A FLUCTUATING DC CURRENT. SO HOW DOES THE EMITTER BYPASS CAPACITOR CHARGE AND DISCHARGE. I CAN SEE WHERE IT CAN CHARGE ON ONE HALF CYCLE THE SINE WAVE, BUT WHAT IS THE PATH OF DISCHARGE ??? THE CAPACITOR IS PUT THEIR TO SHRUNK OR BYPASS THE RESISTOR CORRECT ?? YES I THINK THIS IS CORRECT. SO NOW HOW DOES THE CAPACITOR CHARGE AND DISCHARGE. IT CANNOT DO BOTH THROUGH THE TRANSISTOR. CURRENT ONLY CONDUCTION ONE DIRECTION THROUGH THE TRANSISTOR. I'M NOT COUNTING SMALL LEAKAGE CURRENTS OR EXTRANEOUS CURRENTS. JUST A BASIC TRANSISTOR AMPLIFIER. AND INDIES CONFIGURATIONS WE TAKE IT TO CURRENT ONLY GOES TO THE TRANSISTOR IN ONE DIRECTION. ELECTRONS GO FROM EMITTER TO COLLECTOR IN THE NPN. SO IF THE CAPACITOR CHARGES THROUGH THE TRANSISTOR, WHAT IS THE PATH OF DISCHARGE ???? DOES A DISCHARGE THROUGH THE EMITTER RESISTOR ????? THIS ALL SEEMS STRANGE TO ME STUMPED I AM STUCK ON STUPID. I SIMPLY CANNOT FIGURE THIS OUT. ☹️

@@ANTOINETTE-nk1tm yes, it discharges through emitter resistor.

Wow, thanks :)

Hello, thanks for the comment :) It is really nice I help people all around the world. Wish you good luck with your business

Hehe, thanks for a comment. It complements explanation in the video quite good :)

@@NickElectronics At first thoughts, it seems like an overkill way of controlling the heater in these things. However, they seem to work very reliably under all conditions. A simple mechanical pressure switch would be notoriously unreliable and very dangerous if it stuck on! It’s also great for the folk (like me) who collect used discarded vapes to salvage the Li-ion batteries. The clever little asic stops the batteries from becoming over discharged as it cuts out at around 3V then flashes the LED. I agree disposable vapes are crazy wasteful, and are littering our environment.

​@@ThePrawlin Agreeing that disposable vapes are incredibly wasteful. Also, I believe that in China, such a sensor costs almost nothing, especially considering the huge quantities they produce. So, definetely not an overkill )

FEMM 4.2

Yep. There are plenty examples. Also, STM32 is more powerfull and professional, which gives a lot of space for the future more complicated projects :)

I provide formulas in the video. Resistance is only one parameter and usually process of magnet design is iterative process. Cause there are different limitations: resistance, as you said, magnet peak temperature, space limitations, its power etc. So you do calculations, check wether some parameters are out of tour limits, then recalculate it. Resistance of the wire in reality is a bad thing and preferable to have it as low as possible, but this increases wire thickness and forces you to use more complex control of the magnet. So for magnets you can buy online, resistance is used for limiting peak current as well. In such case by changing applied voltage, peak current and magnet force can be changed

How would you call it then?

Be careful when using resin 3D printed part with UV light - the resin can absorb a lot of it. Something like that.

@@VEC7ORlt Thank you for a suggestion, but It is too long for a youtube 😅I changed the title a little. I believe it fits the video better now. But you have to remember that youtube as a platform kinda pushes everyone to make a clickbait names and thumbnails. Otherwise it is hard to stand out

@@NickElectronics No one is special, and everyone is - in the end how do you even find anything meaningful if all titles are clickbait? How do I avoid this mistake I don't even know I'm making? Wait, that doesn't make any sense. Oh wait I'm not supposed to be searching - just watch this here and bitch in the comments, is that the face of YT these days?

Yep. Because of a colorful film filter 🫠 But sunset lamps usually used as a second light, not the main one. So idk if it is a really big problem

@@NickElectronics all the bits are in there already, might as well add the white channel.

@@VEC7ORlt I should remove the filter (film) to get white color. But without a filter result is much worse. So idk what do you mean by saying "all the bits are in there" 😅

@@NickElectronics you should have added a white channel - all the control bits are there - you've added the micro, made boards. Alternatively you could have replaced the LED with a RGBW or RGBY, you can do pretty cool stuff with those.

@@VEC7ORlt White color passing through a color film becomes not white. How should i have turned it into white? Only by placing white diode above the film and adding another PCB.

I tried it with all the lenses inside the lens body, but the light spot spot was too small for a regular room 🙂

I think it is actually a good idea. However, after giving this design a lot of time to simmer in my brain, I believe the best option is simply using a flat, inexpensive screen. It would give the same result, cause modern screens are quite thin :) When I was working on the badge, aside from the application, I wanted to test 3D printed materials and how accurately dimensions can be printed. Prior to that, I had zero experience with 3D printed parts. I was pleased with the 3D printed parts. At least they are much cheaper than CNC machined ones :)

In reality, the ring is attached to a mechanisms that adjust the lens optic system for the image to be in focus. So these 16 modes are used for some kind of feedback, I guess. You could watch any review of this lens to see that when the ring is rotated, the lens extends. Unfortunately, I could not show this on the video because the lens was broken when bought it and was not working at all, mechanically and electronically. Hope I have answered your question :)

@@NickElectronics so it uses multiple passes of the 16 values to know forward back and speed of change , make sense thanks

Hello. Thank you 🙂 I wanted to make video more dynamic, that is why i did not include detailed explanations. Gray code feature is that only “one bit changes when the slider moves from one position to another”. So from 0 to 1 is “000” to “001”, from 1 to 2 is “001” to “011“. Between two numbers the difference is only 1 bit. Why its better? Because when signal is measured with a microcontroller, slider can be moved at the middle of reading process. Which in case of a binary code leads to a reading mistakes. Cause two bits in adjacent numbers can change simultaneously. With the gray code, even when slider is moved at the middle of the data reading, you either get a previous position or the one the slider was moved to 🧐 Then i just connect contacts of the slider to the pins of the microcontroller. Only 4 pins are needed. After reading those pins (getting 0 or 1) it is just a simple if condition in the code :) For example, if all signals measured are 0000 - first position and first lamp mode. Hopefully my answer was not too long :) Have a great day 🌞

@@NickElectronics No worries AS a Software Developer i find this the Most interesting in such Videos. But makes sense abreally beautiful and well designed lamp! I really Like the controls.imagine this with a clicky aperture Ring haha

@@GamingClubGermany Hehe. Thanks again. If by 'clicky aperture ring' you mean purely mechanical ones that old lenses have, yeah, it would be problematic to read signals withot a signals even existing))

Hello, thank you very much 😊 I am really glad you liked it, cause I put a lot of effort in it 🌞 Next ones are going to be the same quality or even better :)

You can try SN-6027 6025 :)

Google industrial electromagnet. They are big and flat. I believe you have to use similar structure for your design. But overall, all principles described in the video can be applied to your case :) Good luck

Yes, I have an idea to put battery under a shirt ^) But wireless power transfer is not the most efficient way to power the circuit. I think in the direction of a metal pins that would serve as a fastener and + & - contacts. Idea with an LCD screen is also in my head) I hope i will have enough time in the future to realize it :) Probably, putting a screen is the best soultion btw But from the other side, most expensive :)

You are welcome :) I am glad it is usefull :)

I know they are bad for the environment and for health. The video is made only for educational purposes, to understand its working principle :)

For high frequency applications - many layers. For low frequency - solid piece is okay. Eddy currents is the reason :)

ahah)
