To make an emergency lamp out of a car battery as a power supply, you first need to buy a 12V bulb which fits the standard household socket for such a bulb. At the most basic level, cut off the … Continue reading →

To light your new magic bulb, put on a ring with a wide metal band on your middle or ring finger of your “magic” hand. Hold the bulb so the ring touches the base between the side and bottom. When … Continue reading →

Following this test, we wanted to find out the lifespans of different size batteries. Specifically, we measured how long AAA, AA, C, and D batteries from the same manufacturer would last.The results. Battery Time on 200mAh AAA 1 hour 7 … Continue reading →

Fusible links—also spelled fuseable and fusable—serve a similar purpose to a fuse. (You can read more about fuses here.) Just like a fuse, the link is designed to handle a lower current (amp) load than the rest of the system … Continue reading →

The first wave of graphene-based products are being used in the world of smartphones, wearables, batteries, virtual reality, sports equipment, super-capacitors and supercars… and that’s just the beginning. What things have graphene oxide? Graphene is found in charred roasted meat … Continue reading →

Can you get 24V from a computer power supply? So even though you can’t get 24V from the ATX, you can “cheat” by including another DC converter, the PST-DCBP-24V. The best source of power in the computer is the +12V … Continue reading →

Inhaling graphite smoke leads to memory loss, carbon monoxide poisoning, severe throat burns, lung damage, and more. The difference between that and tobbaco or Weed, is that with pencil shavings you’re not getting high. Is pencil lead toxic when burned? … Continue reading →

Graphite and other components of a pencil are minimally toxic when swallowed or drawn onto the skin. If a pencil tip breaks or punctures the skin, contact IPC at 1-800-222-1222 or the child’s pediatrician for medical advice regarding the puncture … Continue reading →

Deep discharges, heat, vibration, fast charging, and overcharging all accelerate the “aging” process. Approximately 50% of premature car battery failures is caused by the loss of water for normal recharging charging due to the lack of maintenance, evaporation from high … Continue reading →

Potassium – Helps to control the nerves and muscles. Chloride – Similar to sodium, it helps to maintain the body’s electrolyte balance. Carbon Dioxide, Total – Used to help detect, evaluate, and monitor electrolyte imbalances. Calcium – A mineral essential … Continue reading →

The average alkaline AAA, AA, C, D, 9-volt or button-cell battery is made of steel and a mix of zinc/manganese/potassium/graphite, with the remaining balance made up of paper and plastic. Being non-toxic materials, all of these battery “ingredients” are conveniently … Continue reading →

The dissolved substances in a solution are called solutes. In the human body, solutes vary in different parts of the body, but may include proteins—including those that transport lipids, carbohydrates, and, very importantly, electrolytes. What are the two major solutes … Continue reading →

A typical lead-acid car battery contains plates of lead alternating with plates made up of other materials, all immersed in an electrolyte solution of about one-third sulfuric acid and two-thirds water. What does a car battery consists of? An automobile … Continue reading →

We now know that charcoal is a substance produced by burning wood (or other organic substances) at slow temperatures, that carbon is an important element, and that activated charcoal and activated carbon are actually the same thing; either will do … Continue reading →

Instead, take small drinks of water until you feel better; then look for drinks with electrolytes when sick. Gatorade contains sodium, potassium and chloride, so drinking Gatorade when sick can replace the electrolytes you lost due to vomiting or diarrhea. … Continue reading →
