Why Do I Need A New Charger?

Here is the most popular question about new technology, and the products we are encouraged to buy. ” Why does every new item need a new style of charging cord? ” Even gadgets of the same make seem to require you to purchase a new charger, as the older style doesn’t work on the new model.

The answer is only too obvious, but it raises the question, aren’t these big businesses making plenty of money, selling us ” new and improved ” gadgetry? I am constantly amazed with all of the changes that are made to virtually the same products. There is no reason to change the simple things, like charging cords.

Most of the new tech items are using the USB port type chargers, and have the ability to recharge from a laptop, or a wall mount type charger, although the basic amperage may be different. Usually there is a safety feature installed to prevent your device from accepting too much voltage.

All of the phones use the same voltage batteries, but the battery designs are different, so you can’t use the old one you have. That way you have to buy a new one, and that generates more revenues for the parent company. Most of the laptops, and notebooks use a battery that ranges from 5 volts to 20 volts, depending on the device.
Almost all of the phones use a 3.6 volt battery. For those not in the know, it takes more voltage than what the battery voltage is, to fully charge. That is why chargers for your phone say they deliver 5 volts, while the battery is only 3.6 volts.

Here’s how to charge any battery enough to keep doing the important stuff.

Fact 1: All past and future rechargeable batteries can be safely trickle charged if you don’t overcharge them. Trickle means low current, like half an amp for an average camera or phone battery.
Fact 2: Small incandescent bulbs such as flashlight bulbs and christmas tree mini lights make great current regulators.

You can plug any USB device into any USB cable and into any USB port, and nothing will blow up — and in fact, using a more powerful charger should speed up battery charging.

Glow in the Dark Mason Jars

 

When we saw this photo for the first time on 500px, it was an instant favorite that we immediately added to Editors’ Choice. Since then, photographer Luca Gerda László has been inundated with requests to share the secret behind her glow in the dark mason jars. Lucky for you, the big secret is about to unravel…

Glow in the dark mason jars

 

The image above is one of my “most famous” photos and I got lots of requests on how I made these glowing jars. I decided to do a step-by-step tutorial for you and I hope that it will help you to achieve a similar result.

I have a lot of mason jars. Small ones and bigger ones, but I think big jars look more cute and magical. Big jars also take a lot of time to paint, it took me about 5-6 hours to paint the jar in the middle of the photo. Be careful with the paint, it is waterproof, so after it dries you may not be able to remove it from your clothes and furniture. Also, be sure to wash your brush right away after using this paint.

You’ll need:

  • Mason jars
  • Glow in the dark paint (get it online or at local craft store)
  • Paintbrush
  • Tap water

Tips

Glow sticks: Instead of glow in the dark paint try using glow sticks. Buy glow sticks online or in your local dollar store, cut into the sticks and splash the fluid all over the jars. Be careful not to stain yourself or the surrounding area. The glow in the dark effect will last only for a few hours.

Mason jar alternatives: If you don’t have mason jars available use clear glass or see through plastic cups.

Step-by-step

1. Wash your jars.

2. Mix the paint with your brush until the glowing particles have dissolved evenly.

3. Make tiny dots in the inside of the jar. The more dots you make, the prettier the jar will look.

4. Dot on one colour first, then the next, etc.

5. Leave to dry.

6. You’re done!

It is this easy. In daylight your jar won’t look that fancy, but at night it will make your room beautiful and cozy. Charge it with a lamp or with daylight and take it to a dark place to photograph!
