⚡Fixing my Universal AC Adapter/Charger with another Electrolytic Capacitor Vol. 2 (w/ my Paper Dolls) - Part 2 (Final) [Nov. 4, 2020]⚡

Here’s my (final) Part 2 of fixing my universal ac adapter/charger w/ another electrolytic capacitor (47uf, 400V) ⚡ and my paper dolls as a company. (Sorry my introduction is awful, but I try my best).😅

If you haven’t seen my ‘Part 1′, then please [CLICK ME!].

BTW: Some of my photo(s) [snapshot by my Honor 8C📱] are combined into one photo 🖼️ using GIMP (2.10.20).

So without further ado, let’s get started:

9th & 10th Image(s): •[9th Image]: Okay so, I take off the hard plastic covers to see the circuitry board. And here you see I pointed out using my solder sucker was two soldering prints that need to remove from the damaged electrolytic capacitor (47uf, 400V). I’m gonna go ahead remove the solder using my soldering iron and the solder sucker. •[10th Image]: Here’s my progress on removing, it takes time and patience though so I’ll try not to be hard.🙂

11th Image: • After a minutes of removing the damaged capacitor (47uf, 400V), I finally succeed.😊 Here you see that there’s a epoxy potty that they’re using to hold the large damaged capacitor (47uf, 400V) was a bit troublesome if I remove it. Also there’s some burn smudge from the circuitry board, I would like to clean that but I don’t have a isopropyl alcohol for electronics.😅 I’ll be planning to get that someday... Anyway.

12th & 13th Image(s) [combined]: • Here the comparison between the old damaged one and the new electrolytic capacitor (47uf, 400V); as you might a guess the new capacitor is small in height than the big one, but at least I picked the right specific volt and ultra filtration specs for the small one.🙂 Now time to solder the new one onto the circuitry board.😊

14th Image: • Here’s the new capacitor (47uf, 400V) finally installed onto the circuitry board by soldering. It seems to me that I don’t need to bend the metal terminal leads, despite the new capacitor was small height. Good for you.😊

15th & 16th Image(s) [combined]: • The excess terminal leads needs to cut off by using this nipper, it’ll make a room for placing.✂️🙂 Now with the solder installation process is complete, I’m gonna go assemble right away and clean my working space.😊 I hope my process is success.🤞

17th & 18th Image(s): • It worked! Yes!😄 My operation was a success, and my paper dolls say that “Good job! You did it!”. Thanks-a-bunch!😁

19th & 20th Image(s): • Now I can finally use the laptop (Lenovo G470) once again! My paper dolls seems to be praised of my soldering hard work!🤗

••••••••••••••••[UPDATE]•••••••••••••••••

Okay so I have two things that I need to be addressed:

#1: Unfortunately, the universal ac adapter/charger had a floss after I installed the new electrolytic capacitor (47uf, 400V) by soldering. Once I plugged into the electric socket, I notice that it takes long to light up the indicator from the adapter/charger for about a minutes or so. It strange that it’s not supposed to be though, usually I plugged in and it quickly lit the adapter before I turn on the laptop.🙁 So I would say it’s bit failure, but at least I could use the laptop once more... Only if I waiting patiently to lit up the adapter.

#2: And finally this is the major one... I’m almost moving out from the (Lenovo G470) laptop to the PC gaming desktop. 🙂💻➡️🖥️ Why? Because my young brother (sibling) is purchasing his own custom and new PC gaming desktop, with better specs of motherboard, graphic card, CPU, etc than the old one (just to surpass the Autodesk Revit’s modern system requirements, and he needs that for his work). My young bro said that once his entire files are transfer to the new one, I will move out from the laptop to his former PC gaming desktop and my files needs to be move right away. As for the laptop, it’ll preserve as a memory and not to remove the hard drive from the laptop. And that’s good news!😃 I do REALLY need that former bro’s PC gaming desktop. And after all it’s already built-in Windows 10 OS with some medium specs from the former bro’s PC gaming desktop 🖥️, which is far better than the laptop’s old specs (Lenovo G470)💻.🙂

• So now I’m planning a final remarks about the old laptop (Lenovo G470) before I moved all of my important files to the PC gaming desktop this month. I have so much memories about using the laptop throughout the years since 2016, and for that I really missed that laptop very much.😌🗓️ Again I’m planning it soon before the laptop will take away from my working desk and replacing it with a single old monitor of his.😊

•••••••••••••••••••••••••••••••••••••••••

Alright moving on...

Overall: • As I said in the 1st update, the universal ac adapter/charger had a major floss... Otherwise I did very well on my soldering process, plus I can use finally the laptop once again. Although I’ll be wait until the light indicator was on.🙃 You know what I probably should earn some money to buy a new one soon, because the old adapter doesn’t seem right though... But overall I did good.🙂👍

• And speaking of, I’m revealing the items’ price and links that I promised:↓

○ The Lotus Desoldering Pump LDPP12 [CLICK ME!] costs ₱64 from Builtmate [CLICK ME!] at Lazada PH (with free shipping voucher I used). ○ 5 pcs 400V 47UF 18 x 20mm Aluminum Electrolytic Capacitor [CLICK ME!] costs ₱77 with shipping fee costs ₱50 from skjsgxycqy.ph [CLICK ME!] at Shopee PH.

Making ammonia 'greener'

Ammonia, a compound first synthesized about a century ago, has dozens of modern uses and has become essential in making the fertilizer that now sustains most of our global food production.

But while we've been producing ammonia at a large scale since the 1930s, it has been accomplished mainly in hulking chemical plants requiring vast amounts of hydrogen gas from fossil fuels -- making ammonia among the most energy-intensive among all large-volume chemicals.

A pair of researchers at Case Western Reserve University -- one an expert in electro-chemical synthesis, the other in applications of plasmas -- are working on fixing that.

Researchers Julie Renner and Mohan Sankaran have come up with a new way to create ammonia from nitrogen and water at low temperature and low pressure. They've done it successfully so far in a laboratory without using hydrogen or the solid metal catalyst necessary in traditional processes.

Choose the right type of capacitor for your project.

⚡Fixing my Universal AC Adapter/Charger with another Electrolytic Capacitor Vol. 2 (w/ my Paper Dolls) - Part 1 [Nov. 4, 2020]⚡

Hi! Today I’m doing a “2nd volume” topic about fixing my Universal AC Adapter/Charger with a new electrolytic capacitor.⚡🙂

Now as you remember from my previous topic [CLICK ME!] well albeit in a short one, I have another capacitor that has a severe damage as the previous one; though this time it’s the large electrolytic capacitor, with a different ultra filtration (uf) and volt (V) of 47uf and 400V. Meaning I can’t used the Lenovo (G470) laptop right because of the Universal AC Adapter/Charger’s issues.💻😟

So I decided to order at Shopee and Lazada (Philippines) for a fresh new electrolytic capacitor (with specific volt and ultra filtration specs),etc... As well as bringing up my soldering tools. And yes this will be my 2nd time doing a solo work on soldering 🙃... But will I failed once again just like I did to my USB Mini Hub? Will find out right now.

So without further a do, let’s get started:

1st & 2nd Image(s): • Now before I repair or replace with a new electrolytic capacitor, I want to show ya the specify my problem with this universal ac adapter/charger once more. You see, after I shut down the laptop 7 hours ago, I head back again to go computer stuff by plugging the adapter through the laptop and turning on... But then I noticed that adapter didn’t lit on the volt adjuster, in which you see these images right now.🙁

•Therefore I can’t used the laptop once again. And my paper dolls say that it could be another faulty capacitor? Hmmm, maybe I’ll go check...🤔

3rd & 4th Image(s): • Ah they’re right! It turns out that the it is a electrolytic capacitor had already leaked on the positive charge side, unlike the negative one. Yup, my paper dolls saw that too though.😯

5th & 6th Image(s): • So now it’s time to fix the universal ac adapter/charger with my usual soldering tools, with one new additional tool that I really needed. 🧰🔧🪛🙂 My paper dolls asking “what is that gray pen-like thing?”.

7th & 8th Image(s): • Well it’s not a pen-like thing, this is called the “desoldering pump” or “solder sucker”. Yup, this is tool that I needed in my soldering tool collection. 🙂 The purpose of this solder sucker is to remove the soldering lead from the printed circuitry board and taking off the damaged the electrolytic capacitor, although it needs to heat the solder before using the solder sucker; and that’s exactly what I’m gonna do... By replacing the old one to the new electrolytic capacitor that I ordered from Shopee. The desoldering pump from Lotus brand (not to be confused with the British car company) model no. LDPP12 however, I ordered that from Lazada - so I’ll give the price and links in the 2nd part.

• My paper dolls saying that “hope you fix properly, so good luck.😊”. Thanks, hope I will try my best of my ability.😉

And I’ll see you in my next part, right now. [CLICK ME!].

Well that’s all for now. If you want to see my previous related topics, then I’ll provide a links down below.↓😉

⚡ My brand new Electrolytic Capacitors⚡

Hi, you may wondering what item are you posting? Well I’m glad you ask.🙂

1st Image: • On the right side, you see are two pieces of ⚡ Electrolytic Capacitors ⚡. I’m actually gonna fix my universal AC adapter/charger for the old Lenovo laptop 💻 that I’m using a very long time. While on the left was the old Electrolytic Capacitor which it removed from the inside after a small explosion and thank goodness it did not damage the entire circuit board.😌

2nd Image: • The next right here, you see I’m working on replacing the old Electrolytic Capacitor to a new one with a little help with my dad and soldering myself (from my learning skills in my college school days). Though my new one is very small and unmatched compare to the old larger one, but at least I chose the right one.🙂

3rd & 4th Image(s): • Here are some comparisons between old Electrolytic Capacitor and the new one. It seems the old one seems busted and it removed from the metal cap, which you see the burning marks as a result.🙂

Overall: •So is it work with the new one? So far when I turned on the old Lenovo laptop 💻, yes!😁 And my mom said that I was so proud of fixing / replacing an electric part ‘for the first time in my experience’, but you know this is just only the beginning 😉. And you may wondering that I’m using my little bro’s gaming desktop this whole time, while I’m waiting my parcel. Hope the new Electrolytic Capacitors I ordered will last long, but for now my work here is done!😊 • I order these two new Electrolytic Capacitors [CLICK ME!] for only ‎₱10 per. each, plus shipping fee for ‎₱45 with a total of ‎₱65.🙂

BTW: What is a ⚡Electrolytic Capacitor⚡? Please [CLICK ME!].

Anyways, that’s all for now and thanks for listening my story😊.
