Graphite is only the conductor, that is, it cannot supply any current/energy/power to the device. Hence it cannot be the alternative of the cell.

Yes it's working because ✏️ pencil led was good conductor of electricity So circut was completed 😎

AA 1.5v x 2= 3v rated voltage. Don’t work.

El grafito es conductor pero no tiene la carga de 1,5V de la pila faltante. Funciona el RC con la mitad de la carga? Voy a probarlo 😉

This is rubbish, the device is designed to work from 3 volts using 2 batteries. The graphite becomes a massive resistor, stepping down the 1.5 volts of the single battery to a very small voltage. It can't possibly work.

Or could have used literally ANY metallic object.

Or you buy a new battery instead of a new pencil.

Is this the right emergency way to handle a motorbike that has broken down because the battery is dead?

A simple demo of how to use this Bosch C3 battery charger in a case of dead battery. Remember to switch the supply on after you connect the terminals. It doesn’t charge dead or faulty batteries. Thankfully, it worked as expected in my T-Roc and saved me some unnecessary headache.

Life Hack: If you see a Tesla stranded at a supercharger, and unable to charge, likely the 12v battery is dead. If the 12v battery is dead, you can use this technique to jumpstart the car and open the frunk, even if it's locked. Meaning: every Tesla stranded is a free loot box for you.

Jersey dude uses his fully charged DJI to approach a drone hanging out over Picatinny. Gets near and it drops like a gnat. Dead battery. Seen reels / tiktok videos about other DJIs with unexplained battery drain too. Wonder if it's some sort of anti-drone effort by feds

In 2013, Tesla showcased Battery Swapping as a alternative to Supercharging. It would swap the battery in about 90 seconds. The price for a swap was comparable to that of a full tank of gas. Additionally, owners had two options: • Swap Back: On their return trip, they could re-swap to their original battery pack at no additional cost, ensuring they kept their own battery. • Keep New Pack: If they preferred the swapped pack (e.g., newer or less degraded), they paid a fee based on the age and condition difference between the packs. Ultimately, the program was abandoned in 2016 due to complexity, low demand, battery degradation concerns, and the rise of the Supercharging Network.

All the "agent orchestrator" GUIs are vibe coded JS apps. They use too much RAM and CPU. My battery life goes from 10 hours to 2. So I started building a native alternative for MacOS 👀

💭: LOL) Last day, battery dead. 🦈: Battery dead! You saw that too, P’? 🦈: At that time, the voice in my head was: “When I get home, I have to pack my bags, take a shower, go check in to the hotel.” I completely lost my mind at that point. Sorry about that. Our poor baby he was operating on fumes 😭😭 MAYBELLINE CANDY EST #MaybellinexEst

Today a blog post in which our character throws some crazy shapes on an alternative method of inertialization sometimes called "dead blending".
