I am just sick and tired of this my innjoo f2. For couple of days now, the tab has refused to come-up or charge and I have tried series of chargers all to no avail. The only thing the tab does while I plug it to the socket with its charger is to be showing BLINKING BATTERY LOGO which I tried all through the night yeterday till this morning and it was still BLINKING! Not even a % charge. The tab is lifeless and the battery is equally non-removeable, thus, is this not alarming? Has anybody experienced these scenarios? Gurus in the house, please, I need urgent help as this tab wanna drain my blood to the very zero level oooo............... This is my whatsapp handle; 07033135972 incase..........!

apparently you are in itel 1701 thread....try pressing volume down and power button together at the same time......it might help your situation.

sir. i was able to get car acid battery today and i was able to etch a pcb board with the hydrogen peroxide i bought at chemist shop......i couldnt believe it worked. i saw d solution changed to green..d same i use to see on youtube videos.......just to let u know sir......#wekeeplearning

nisol:
Glossy paper is available from those who sell
printing materials... those who sell ordinary stationery
would not know what you are talking about.

thanks very much bro..i really appreciate your guidance.

please what is the local name of glossy paper? paper shop couldn't get what I mean.. tanx

nisol:
@temizeee
hydrogen peroxide in mouth wash is too weak for etching; and yes i mean car battery seller, the acid usually comes in a small plastic jerrycan

tanx alot. will get from the source u said....

nisol:
@temizeee

hydrogen peroxide sold in the chemicals section of most markets (particularly soap makers)
you can buy sulfuric acid from those who sell car batteries (buy the diluted one)

thanks for the help, but can i use the hydrogen peroxide at chemist shop? i saw one today they wrote hydrogen peroxide on it they also call it mouth wash
also u mean car battery seller? like can i get it from road side battery repairers? ( d so called REWIRE)? TANX FOR D RESPONSE.

nisol:
mix acid to be used in etching of the board

I use hydrogen peroxide + sulfuric acid + water

the higher the concentration the faster the etching, however if concentration is
too high it would damage the board.

please where can I get sulfuric acid and hydrogen peroxide in Nigeria?

Joel3:
Benin

chai...m in oyo state shuuuuuu

Joel3:
any one want to sell?

where do you stay? i am willing to sell mine

Savotech:
I dont think they sell the solution at local shops. And even if you see, they might be concentrated which yoi probably wont know how to dilute it. Its better you get from a shop that specializes on electronics and pcb materials and not to find out a chemical shop.

You can get them in lagos at oshodi but if you are outside lagos, the guy selling it can still transport it to you using the 18seater bus or whatever. If you are interested i can give u the number of the guy that sells. He didnt pay me for advert so i wont post his number here. Contact me on Savotechng@gmail.com and i will link you to him for free. No hidden charge...

But remember toake pcb u will need hand drilling machine also.

thanks very much sir!!!

Jamzig1:
Thanks a lot sir..I will take to the invaluable advice. Personal learning seem a little bit tasking although i have started that. Do you know of any training institute where i can learn the technical know-how probably while on break? I am based in Lagos. Also i would appreciate any e-book you can refer me to. Thanks

please house i really need to learn how to make pcb are locally made from my Google search i discovered ferric solution/hydrogen peroxide are used in making them....please where do they sell these chemical in local shops or does it have anyother name? tanx house

ritababe:
did u root it

ain't d one with dead phone,,, d guy already brought his phone back to life.

sad news...my morning star 45amp CC has died....my folks in the village hv been complaining that the inverter barely lasts 10mins for a couple of days now...was finally able to go check it, thinking twas the heavy rains or something...but alas in bright sunlight the CC was displaying 0amp,i checked the log and this zero harvest started 10days ago....they reported no ligtening strike...so am rally at loss what might hv damaged it......has anyone experienced this b4?...and any luck in repairing it?
the unit is about 21 months old. 4 x 250w 24v renogy panels connected in series. input voltage usually hovers around 130v.
system is hooked up to 2 x 200amphr luminous batts, and 1.5kva 24v luminous inverter....

any suggestions would be welcome, attached is a pic of the unit

remove the + & - pv cable from the cc... retwist it very well n reconnect...afterall, remove all connections from the cc n reconnect them.

Barezzi:
@temizeee
Very shocking indeed!
Such a dangerous setup, no protections, exposed high voltage cables... and that looks like the guy's main lounge!
If e kill am dem for say na the grandma for village...

na so!

kiekie1:
Been a while Bro! How is the family? Happy indepence ...

doing good o.....i wish you the same. how is business?

New cc setup

So i decided to add more panels which will be sufficient to charge d ba3s,installed 60amp mppt(itracer),30a cc as well all supplied by KIEKIE
Now the system is running almost offgrid...went there last week he said he doesn't really care much about public power supply since the upgrade
I will advise everyone to be careful of the installer that you call to do installation......i believe the ba3 will probably explode one day or get dead if there wasn't correction...
Just an advice tho.
D new cc pix follow:

Checking the connection,i discovered that the installer connected the 8 panels in series (voc)=20.2 d norminal voltage of each panel is 17.8v+_ i was reading 152.8v from the panel to that tin can(cc), and that is feeding a 24v 800ah deep cycle ba3. I was shocked!!!
after i opened the cc here is the view

Some months ago,a friend seek my help to check his solar setup.he said that his system even shutdown on full sunny day...on getting there, i went up to see d panels of 80watt of 8 pieces,getting to the controller this is what the installer mounted as charge controller. pix......
