Hot tip (pun intended) tin your sliding iron. All you need is a bit of solder and a sponge. Though that tip is bad enough to maybe need a brass “scrubby”. Your soldering will be faster, easier, and stronger.
If this works I am installing an icon to my home with your channels photo and I will call you The Savior from that day onward. heheheh Many many thanks.
Very poor soldering!! It will decrease the voltage, heat up the joint points. Also the wires diameter is too small for powering car audio. Diodes will also drop the voltage. Beware!!
this is essentially a low-pass filter. peronally i wouldn't use the diode since there is vertually impossible to get reverse current from the car power unless you use this device directly right after the alternator and before the rectifying circuits. however, i would put a schottky as flyback diode with the inductor for back emf protection. Without the back emf protection, thay inductor might fry your audio equipment once you turn off the power.
@@timwheeler1503 Oh, this is actually a rather big topic. The aim of the filter is to remove the fluctuating voltage and since equipments within a car are all conneted together which including both resistance (like lighting) and inductance (like fans) load. Inductance load can and will introduce fluctuating voltages within the whole electrical system and the filter can only remove or rather, improve, some of the fluctuation. If you are serious about this, use an isolating power supply for your audio system. For a cost-balanced solution you probably could use a buck converter with a LDO. For cheapest solution, you can use a inductor with a capacitor form as a Low Pass Filter but be aware that flyback diodes are recommanded to protect both your car and your audio equipment. Let me know if I can be more helpful.
@@lialex2517 you put that diode across the inductance load parallely and against the power current direction. Which means Positive (+) of the power connect to the negative (-) of the diode and the positive (+) of the load; Negative (-) of the power connect to the Positive (+) of the diode and Negative (-) of the load. In this way, when power is on, the load will receive power from the supply as normal but not the diode since the negative is side connect to the positive side; when the power is off, the energy stored within the coil (fan) will be released back to the circuit but the current is reversed, now the diode will be the 'low resistance path' for the current to go back to the coil agian instead of going back to the power supply reversely until the energy is exhausted.

This is a sample only, When you apply practically, you have to solder those on a board. Since the voltage is arround 14.2V while battery is being charged, there is not voltage issue.

Yes of cource.

Thank you. Use a good color laser printer 🙂
I've never seen worst solders in my life!
Thank you :-)
Perfect example of how "not to solder" something...
In practice, yes, you must use a PCB.
Can i use an ultra capacitor or a super capacitor instead of electrolytic?
You can use.
Thank u for this information
you are welcome

How come this has a sinhala (srilanka) audio part?
because of my mother tongue

yes

yup, this a mess of a job
When engine on, the volate level is arround 14.2 volts. therefore, the voltage drop is not an issue.
The tip of the iron is way too small for this job.

What is the best way to build a noise filter for car audio?

Can I ask put on where?
@simengfu7352 Can I ask schottky put on where? how to do it? Thanks

Why the diodes?
Is it to prevent people from hooking up power backwards?
@@randallhatton4819 that is one use but not the reason in this case. In this case it prevents any ac current that may be induced in the system.
you can see more in the videos
Very bad soldering
Yaa :-), when you do, do it well :-)
