@ahmedxm01 Beautiful! It's great seeing fellow Nigerians taking the right steps to restore the nations critical infrastructures. Good gesture XM.

Nigeria is ours to fix, let's take back our nation and get it working again!

إذا كنت تفكر تشتري منظومة طاقة شمسية ليثيوم للبيت،

فانتبه...

أغلب الناس تقضي ساعات وهي تقارن الأسعار،

وتفاوض على الخصومات،

وتسأل عن عدد الألواح.

لكن السؤال الأهم الذي نادرا ما يُسأل:

هل البطارية التي ستشتريها
ستخدمك 10 سنوات أم ستبدأ مشاكلها بعد سنتين أو ثلاث؟

الفرق بين منظومة ناجحة

ومنظومة فاشلة غالبا يبدأ من البطارية.

أول نقطة أركز عليها دائما هي نوع الخلايا.

إذا كانت البطارية من نوع LiFePO4 فهذا يعتبر الخيار الأفضل للاستخدام المنزلي.

ليش؟
لأنها أكثر أمانا، وتتحمل درجات الحرارة بشكل أفضل،
وعمرها الافتراضي أطول بكثير مقارنة بأنواع الليثيوم الأخرى.

ثاني نقطة مهمة جدا وهي التوافق مع الإنفرتر.
كثير يشتري بطارية ممتازة ثم يكتشف أن التواصل بينها وبين الإنفرتر فيه مشاكل.

تأكد أن البطارية تدعم بروتوكولات الاتصال مثل CAN أو RS485 وأنها متوافقة مع الإنفرتر الذي عندك.

لأن نظام إدارة البطارية BMS لازم يكون قادر يتواصل مع الإنفرتر بشكل صحيح حتى تتم عملية الشحن والتفريغ بأمان وكفاءة.

ثالث نقطة لا تتجاهلها أبدا.

اسأل عن عدد دورات الشحن والتفريغ.

البطارية الجيدة اليوم تعطي أكثر من 6000 دورة.
هذا يعني سنوات طويلة من العمل قبل أن تبدأ السعة بالانخفاض بشكل ملحوظ.

أما إذا كانت الدورات قليلة فالسعر الرخيص الذي وفرته اليوم قد تدفع أضعافه لاحقا. أيضا انتبه لعمق التفريغ DoD.

البطاريات الممتازة تسمح لك باستخدام 80% إلى 90% من سعتها الحقيقية.

يعني إذا اشتريت بطارية 5 كيلووات ساعة فستستفيد من معظم طاقتها المخزنة فعليا.
ومن الأخطاء الشائعة أن البعض يشتري البطارية قبل أن يحسب احتياجه الحقيقي.

احسب استهلاك البيت أولا.

هل تحتاج 5 كيلووات ساعة؟
10 كيلووات ساعة؟
15 كيلووات ساعة؟
اختيار السعة الصحيحة يوفر عليك المال ويمنعك من الوقوع في مشكلة نقص الطاقة مستقبلا.

ولا تنس التأكد من وجود نظام BMS ذكي داخل البطارية.
هذا هو العقل الذي يحميها من الشحن الزائد والتفريغ العميق وارتفاع الحرارة وعدم توازن الخلايا.
وجود BMS قوي قد يكون الفارق بين بطارية تعيش سنوات طويلة وأخرى تتلف مبكرا. وأخيرا...
إذا وجدت بطارية LiFePO4،
بدورات تتجاوز 6000 دورة،
وعمق تفريغ 80% إلى 90%،
وتدعم CAN أو RS485،
وضمان حقيقي من 5 إلى 10 سنوات...

فأنت غالبا أمام بطارية تستحق أن تضع أموالك فيها.

Wallahi, as much as I hate to say it, Northern Nigeria is a major part of Nigeria’s problem.

Imagine someone from Zamfara voting for APC and encouraging others to vote for APC because of ₦5,000, despite all the insecurity, poverty, and suffering in the state.

We never see anything.

[TERRORIST SURVIVOR 💪🏽 @GbolahanOlanyi0]

🚨 As a Kidnapping Survivor, I Can Tell You This: These Bandits Can Be Caught Easily

After confirming their location, the government can easily use night vision to track and attack them at night.

From my experience as a kidnapping survivor, these bandits are not as difficult to catch as people think. Most of them take hard drugs at night and sleep heavily until the next morning.

If not for the chains they used to lock us up, I would have escaped much earlier.

The government can deal with this problem if they truly want to. They know what they're doing, sha. 💔

At this point, na only God fit save person. 😭

[Engr. Nasir M. B. @nasirumb]

Isn't it time to organise an apolitical wake up call in the North to protest the killings, kidnappings, banditry, etc? Organise nonviolent marches, create visibility, make noise, be heard, remind leaders of there responsibilities...? @shehu_mahdi, @CaptJamyl , etc? https://t.co/GlDV5x259K

[KEBBI KING 👑 @Kebbi_kingjr]

For over 3 weeks now this two elderly men are still in captivity

Alhaji Yahaya Tanko Besse and Alhaji Muhammad Mai Barga Besse have been k!dnapp€d and are still being held by kidnapprs demanding ransom of #400m that they clearly don't have😭
A post made by @DanKatsina50 earlier today highlights that the kidnappers are in Birnin Gwari forest
Pls Nigerian authorities do your due diligence.

This is heartbreaking. No family deserves this pain.

While we pray for their safe and quick return. We are begging Nigerian government to end insecurities in the country.

@grok @Fariderh__ True, the underlying assumption is that the plugs are properly wired. If not, there are tons of possibilities that result in sparks and bangs including the utility company itself waking up wiring or phase reversals along the way...

[Engr. Nasir M. B. @nasirumb]

@grok @Fariderh__ You got one scenario right - wherein there's more than one phase and both sockets are on different phases. However, if everything is on one single phase, then nothing will happen.

[Mayor Of Calabar @Uno_009]

His name is Nuru Aliyu Garwa, a former Senior Special Adviser on Community Development, pls note that, on Community Development to the Katsina State Governor.

He recently resigned in order to contest in the House of Assembly to represent his people.

On May 13th, an eight year old boy was abducted while coming home from a Quranic School, his family were contacted and a ransom of 50 million was requested by the bandits or kidnappers.

The price was negotiated and brought down to 17 Million which was paid. After this, the family reached out to a security outfit known as Violent Crime Response Unit in Katsina State.

The Unit swung into action and started their investigation. The investigation led to the arrest of 6 of the bandits on the 23rd of May.

This arrest of the six led to the arrest of the other member and boss, Nuru Aliyu Garwa, the former SSA on Community Development to the Governor on the 24th of May.

In his house they found 7.5 million in a Ghana must go bag which the Security Unit believed is his own share of the ransom, they also found the bike used in operations and some other items.

However, investigations still ongoing.

ALLAHU AKBAR! 🤲😭

Today, I witnessed a scene that shook my heart and reminded me of the reality we often forget.

A dove stood before me in its final moments. It struggled silently, fighting a battle known only to Allah. I looked closely, thinking perhaps it had been injured or attacked, but I found no visible wound. Then, before my eyes, its soul departed.

At that moment, I realized how helpless every living creature is before the decree of Allah. No wealth, no status, no strength, and no loved one could stop death when its appointed time arrived.

As I watched, verses of the Qur’an and sayings of the Prophet ﷺ about death and the departure of the soul flooded my mind. The reality that we read about and hear in sermons suddenly stood before me in the form of a small bird.

What moved me even more was what happened afterward. Within minutes, insects began to gather around its lifeless body. In a very short time, the same body that moments earlier was alive, moving, and breathing had become motionless and abandoned.

I could not help but ask myself:

One day, will this not be my story too?

One day, death will come for me exactly as it came for that bird. It will not seek permission. It will not consider my plans, my ambitions, my family, or my unfinished dreams. It will arrive at the time written by Allah, and no one on earth will be able to delay it for even a moment.

Then what will remain of me?

Not my possessions. Not my titles. Not my popularity.

Only my deeds.

The prayers I performed. The good I did for others. The kindness I showed. The Qur’an I recited. The charity I gave. The wrongs I avoided for the sake of Allah.

My dear brothers and sisters, this world is temporary. Every day that passes brings us one step closer to our meeting with Allah. Let us not be deceived by the distractions of this life. Let us prepare for the day when neither wealth nor children will benefit us, except a heart that comes to Allah in sincerity.

May Allah grant us sincere repentance, strengthen our faith, bless us with righteous deeds, and grant us a good ending. May He make our final words "La ilaha illallah Muhammadur Rasulullah."

Ameen Ya Rabbal Alameen. 🤲😭

[Imtiaz Mahmood @ImtiazMadmood]

The year was 1957. Inside a modest Sony research laboratory in Tokyo, a 32-year-old physicist named Leo Esaki was doing something that looked almost embarrassingly simple. He was pressing a tiny sliver of germanium semiconductor between two electrodes and watching what happened. No massive particle accelerators. No sprawling university budgets. Just a quiet man, a small crystal, and an idea that the textbooks said shouldn't work.

What Esaki noticed was extraordinary. Electrons weren't behaving the way classical physics demanded. Instead of climbing over an energy barrier the way any sensible particle was supposed to, they were slipping straight through it. Vanishing on one side and reappearing on the other, as if the wall simply didn't exist. This was quantum tunneling, a phenomenon that had been theorized for decades but never cleanly demonstrated in a semiconductor until that moment.

The implications were staggering. Esaki hadn't just confirmed a ghostly quirk of quantum mechanics. He had shown that it could be harvested, controlled, and put to work. The device born from his discovery, the tunnel diode, could switch between states faster than any conventional transistor of its era. It was a signal that the future of electronics wouldn't just be about building smaller components, but about bending the rules of nature itself.

Physics laboratories across the world took notice almost immediately. The tunnel diode ignited a wave of research into quantum devices that rippled from Bell Labs in New Jersey to research centers in the Soviet Union. Scientists who had spent careers working within the comfortable boundaries of classical electronics suddenly found themselves peering into the strange, probabilistic world of quantum mechanics.

In 1973, the Nobel Committee in Stockholm made it official. Esaki was awarded the Nobel Prize in Physics alongside Ivar Giaever, the two of them recognized for independently illuminating the tunneling phenomenon from different angles, Esaki in semiconductors and Giaever in superconductors. It was a recognition not just of two brilliant careers, but of an entire new chapter in the story of physics.

Today, Leo Esaki turns 101 years old. Born in Osaka on March 12, 1925, he has lived long enough to watch the quantum principles he uncovered in that Tokyo lab become foundational to the technology billions of people carry in their pockets every single day. The man who once watched electrons walk through walls is still here. And the world he helped build is still catching up to him.
