No neutral lights and buzzing capacitors : r/smarthome
Pretty stumped - are noisy capacitors just part and parcel of this type of switch or are there quieter capacitors I could use rather than the manufacturer provided ones (again the ones provided by Sonoff and Lonsonho are completely different - the Sonoff one has a small PCB with the capacitor and some other components whereas the Lonsonho one is a package of two capacitors wired
Smooth out LED flicker with caps?
Adding a capacitor would smooth the voltage, increase the average voltage, and potentially improve brightness. Begin with a small capacitor (e.g., 100nF to 1μF) to observe its effect. Gradually increase capacitance and monitor voltage and current.
People in the UK using smart switches with no neutral wire
The switch I bought came with a capacitor which I installed so no flickering happens, but it makes quite a disturbing buzzing/flickering noise whenever the light is on. For anyone with experience in this matter, Is this the case of needing a better quality capacitor, needing a more compatible light bulb, light switch or did injust install the capacitor wrong?
which capacitor to use?
which rating capacitors should i use for these lighting bars - i dont want to burn out the leds! which means that to cope with all possible scenarios you should be thinking about a 35V rated capacitor to be on the safe side. VerticalScope Inc., 111 Peter Street, Suite 600, Toronto, Ontario, M5V 2H1, Canada
Capacitor to smooth out rapidly blinking LED lights?
As the LED dims (flashes slower? or flashing with bigger gaps of "off") the capacitor is reducing the intensity of the blinks. My hope was that I could simply solder capacitor value X in line with
Is it normal for capacitors to have lower readings than
Usually the capacitor''s specified ESR range can be found by downloading a spec sheet for that particular product line from the manufacturer''s website and then looking up the capacitance and voltage ratings for your specific capacitor on
ps3 Les Paul Capacitor Fix : r/GuitarHero
Hello all. Im trying to fix my gh3 guitar by replacing the 220uf 10v capacitor due to a sync issue. I successfully replaced the capacitor and I have continuity. However, when the I insert the batteries, the red LEDS are all on with a solid light. The power button doesn''t seem to do anything. The red LEDS are just solid with no blinking.
DIY Capacitor Fix for Flickering Lights: Is It Safe?
Customer: Question on capacitors. To start, I am a DIY guy and not an electrician. I do have a newly constructed house and some of the circuits seem overloaded. In my office, when printing, the lights flicker. That said I ran across the idea of adding capacitors to the main panel directly tied to a 2 pole breaker.
[SOLVED]
If the card is still under warranty, set it aside until you get the repaired one back. If it isn''t, remove the dead capacitor, clean the area as well as you can to reduce the

Can you upgrade capacitors? LED light repair : r/AskElectronics
I got a cheap set of mains voltage LED workshop lights from Lowes a couple months ago. They are in my laundry room and off most of the day. One day I turned them on and noticed 1 of the 2 ''tubes'' is flickering. As I suspected, its a blown capacitor, easy to fix. Though I wanted to know if I can ''upgrade'' the capacitors so they last longer.

Why is it okay to connect the capacitors like this
Well it is also "a maximum voltage when fully charged" that is kinda the same thing :) look you have a cap charged to 0 volts. You apply voltage V to it and the current starts to flow and the cap starts to charge.
Ultra Capacitor as a Source for Smart Street Light
We can use UltraCapacitor as a power source replacing the Battery to achieve a feasible Smart Street Lighting System. Although we need more complex controller that can increase the
Capacitor for LED flickering
Capacitors can in fact be used to reduce flickering, but they need to be in parallel with the LED diode itself, not the mains connection. I have some electronic motion
Why do we use capacitors for power factor correction
I edited my comment to fix that. So, "negative power" would really only be produced when the current is 180 degrees out of phase with the voltage. Resistors, inductors, and capacitors don''t do this. Generators and theoretically

Smooth out LED flicker with caps?
I also tried putting the capacitors directly on the DC output and then using a resistor to reduce the LED power. At this time I was measuring DC current. The DC current at the LEDs with no filtering was about 140mA. Adding the capacitor brought it up to almost 300mA. Adding the resistor after the capacitor brought it down to about 260mA.

Can ultracapacitor be used as a power source for smart street lighting?
CONCLUSION We can use UltraCapacitor as a power source replacing the Battery to achieve a feasible Smart Street Lighting System. Although we need more complex controller that can increase the efficiency of the current proposed setup and we can use soft switching for better performance.[]
How to add capacitors to LED lights?
For adding capacitors, first need to check the supply voltage and as well as the voltage across each LED, after that you can use any capacitance value capacitors with voltages let’s say if voltage across LED is 4V, you need to place 6V rating capacitor or you can also use 16V rating capacitors.
Why do LED lights need a capacitor?
As capacitor play a vital part in reducing the signal fluctuations/flickering. In LED lights, there is a capacitor attached in parallel to the diode and also recommended to place a capacitor with power lines to reduce power fluctuations.
Why did I install a light switch without a capacitor?
I installed it without the capacitor because I use ordinary (incandescent) bulbs and there can not be any flickering. I think the provided capacitor is only for LED lights to prevent them from flickering. That switch burned out yesterday when my mother pressed the touch sensor to turn the lights on.
Why SMD LED is operating when connected to ultracapacitor?
As can be seen that the SMD LED is operating when connected to UltraCapacitor. Although in current setup it can be seen that the capacitor are connected in series which is not an ideal way to connect capacitor. These UltraCapacitors on later stage were connected in parallel as the capacitance increases in parallel. VII.
Can I use a capacitor in parallel with an LED bulb?
So try this first (ie, one LED, the rest incandescent). However if the issue is indeed that the PWM frequency is too low, the problem with a capacitor in parallel with the LED bulb is that the discharged capacitor acts like a short and will draw a high current when the bulb turns on, which may cause problems with the switching MOSFET.
