I would not worry about that because I have been interested in your off topic about my endeavors about my Panasonic switching power supply that the circuit boards are crap and how you are trying to resolve your own issues with your experience with the substance in your switching power supply so it is not completely off topic...Last edited by sam_sam_sam; Yesterday, 06:27 PM.

Actually I did have a few 27uf @ 50 volts but they were in a container that is odd values or low voltage capacitors that I mainly use for 5 volt switching power supplies I did not even think about looking in this container because I was looking for some 3300uf @ 35 volt I have some but they are not brand name ones for this switching power supply but I am not going to change them because of the quality of these boards and that I had to do a repair job in four places...

Probably but if I were doing this I probably would power the LED light bulb on a lower voltage so you would have lower current draw but not to low that your brightness would suffer and you would not be able see anything
The one thing that I find with LED devices is that they have a tendency to over current the LED light bulb to the point that it drastically reduces the life of the LEDs or the quality of the LEDs are crap to begin with...Last edited by sam_sam_sam; 07-23-2024, 02:04 PM.

I have a suggestion for you and that is get a cell phone battery pack and use it to power these things but the issue you might have is that if the stand by current is not high enough then it might not turn on after the first time however if you modify the battery pack a little bit an use a relay then you could have two light levels one on 4,2 volts and one on 5 volts
One way around this is to reverse engineer this a little bit and power the LED light bulbs on the 5 volts and the motion sensor circuit on the 4.2 battery voltage with it on BMS board these are very inexpensive to buy...Last edited by sam_sam_sam; 07-23-2024, 01:57 PM.

Well I had some time today and got the small value capacitors done on second switching power supply but unfortunately I do not have any brand name 3300uf @ 35 volt capacitors output supply rail I have to order some for these switching power supply boards I do not very many high UF value capacitors on hand in my capacitor bins case I order them as I need them because of cost per capacitor
I should order some 1500 , 2200 and 3300 @ 25 and 35 volt ones if the diameter are different or the height is different I quite a few low voltage ones like 6.3 , 10 and some 16 volt one of those values...Last edited by sam_sam_sam; 07-23-2024, 01:23 PM.

The hardest part of writing your own firmware is to get the algorithm working correctly for how long to leave the heat on and control the temperature and be consistent with out overshooting it or undershooting it the more consistent you are with it the better the performance will be and less wear and tear on heating element is going to be and the faster you will dry your clothes with this setup and weather or not to use a humidity sensor to automatically end the drying cycle if you choose to use this as feature or not...Last edited by sam_sam_sam; 07-23-2024, 07:38 AM.

Unfortunately I was not able to get recapping this switching power supply because of more important things came up hopefully I can get to not this coming up weekend but the following weekend I hope I can get this finished and and get it back up and running again...

Thanks for posting this I was not aware that there was a product available like this...

I find that if you heat the area around the edges of where the component is going to be on the board then use the soldering iron to mount the component seems to work most of the time for me but you have to be patient and you have to cover the areas where you do not want the heat to be exposed to like surface mount capacitors and resistors and anything that will get damaged by excessive heat
Now —>
If you are doing surface mount components then you might be better off with a tweezer style soldering iron will make your life much easier and doing this job easier...Last edited by sam_sam_sam; 07-21-2024, 08:29 AM.

Please show some pictures of the board in question so we can give you the correct information...

I going to try to recap the other 18 volt @ 20 amp switching power supply and modify the secondary power supply board of the original switching power and get this one up and running soon I hope so that I have two of these soldering/desoldering stations up and running ( with two different size tips for the iron and for the gun )
Then work on the battery operated version with the setup that I talked about in another post a while back and finally complete this project once and for all ( The plan is to use one of my other soldering iron controllers that has the sleep function for the...Last edited by sam_sam_sam; 07-20-2024, 04:56 PM.

These capacitor values are prone to failure because of the value and there physical size especially in switching power supply and if see these values I replace them on site even sometimes if they are brand name capacitors especially if the device is giving trouble just to rule out the possibility that this is issue...

Please show us the front and back of this switching power supply
I would also agree with this as well
Was this switching power supply in storage for a long time meaning that it was “new old stock” if this the case you should replace every single capacitor that is less than 100uf and any capacitor that shows any signs of leaking or bloated ( pop the the top of the capacitor or leaking out the bottom of the capacitor ) of any kind
I have bought these FSP power supply before and found that just about every capacitor was bloated or leaking...Last edited by sam_sam_sam; 07-19-2024, 05:38 AM.

I bought three of these Sparkle Power FSP460-60GLC - Computer Power Supply 460Watts recap need
I have bought computer switching power supplies from Electronic Goldmine before and every one of them the capacitors were bloated and or leaking out of the capacitors so I am sure that these are going to be the same way five or six years ago I had bought some 300 and 350 watt computer switching power supply from Electronic Goldmine these are all from FSP brand
Here is the listing for this switching power supply they only had three of them in stock and I bought all three of them

I have decided to go ahead with this project once again because I now have a metal enclosure that I can house all of the components and install a cooling fan to keep all of the components cool the 3D MOSFET board and the buck converter board the battery holder from a Ryobi battery charger that the charging board went bad ( from an eBay seller bought as is not working ) and would cost to much to repair now just have to find the time to do this projectLast edited by sam_sam_sam; 07-17-2024, 05:46 AM.
