Solar cellphone charger

A little soldering is all it takes to make this cool little emergency cell phone charger.

Please note, you'll also be cutting the wire on the cell phone charger, so make sure it's not the only one you have! You can often find cheap chargers at stores -- it doesn't matter if it's AC or car compatible, since you'll only be using the end that plugs in your phone.

MATERIALS:

  • 1 Altoids Tin case
  • 2 Mini Solar Panels (3V 20mA each)
  • 1 Solder (3")
  • 1 Small Heat Shrink Tubing (4")
  • 1 Large Heat Shrink Tubing (4")
  • 1 Double Sided Tape (3")
  • 1oz Flux
  • 1 Solder Iron
  • 1 Heat Gun
  • 1 Wire Stripper
  • 1 cell phone charger

STEP 1: Cut wires & tubing

Take the 2 solar power panels and cut all four wires to about 1" in length. Cut 1/4" of plastic off of the tip of each wire with the wire stripper so copper wires are exposed. This exposed wire is called a 'lead.' Cut the small heat shrink tubing into four equal pieces (1" each). Slide the small heat shrink tubing onto both black wires.

STEP 2: Solder solar panel leads

Using a toothpick, paint leads with flux on a red wire from one solar panel, and a black wire from the other solar panel. Put those two leads together, and solder using your piece of solder and the soldering iron.

STEP 3: Heat-shrink tubing

Slide small heat shrink tubing over the leads you just soldered together. Heat the tubing with heat gun just enough for it to shrink.

STEP 4: Cut phone charger wire

Cut off the wire from your old charger to about 2.5 feet and strip off 2.5" of outer plastic from the loose end. Cut 1/4" off of each of the inside wires to make leads. Slide the full length of the large heat shrink tubing onto this main wire for later use in Step 6.

STEP 5: Flux, solder and heat-shrink loose leads

On your main wire, slide a piece of small heat shrink tubing onto the red wire. Flux all loose leads of main wire as well as the solar panels with the toothpick. Solder red leads from main wire and solar panels together. Repeat with black wires. Slide heat shrink tubings over these soldered leads and use heat gun to shrink.

STEP 6: Test charger

Test the charger by connecting it to a phone under bright light.

STEP 7: Heat-shrink solar panel leads

On your main wire, slide large heat shrink tubing over the two soldered leads which connect to the solar panels. Use the heat gun to shrink the tubing.

STEP 8: Tape and close

On the back of the solar panels, cover the two brass rivets with double-sided tape (so they don't make contact with the Altoids tin.) Tape the two solar panels on the inside lid of the tin. Tuck the main wire into the case and close. Go somewhere sunny (Florida is nice) and charge it up!

Bayani Agbayani Nagwala?

When I heard the news on radio the way home from work,one thing caught my attention. It was the youtube video of Bayani Agbayani daw arguing/altercation with someone due to minor traffic accident. So what i did was searched it my self in youtube and it was very disturbing video indeed, bayani was not aware he was being recorded (unclear video) probably by a cellphone cam. But all of us have some commit mistakes in our lives and i believe bayani was not that bad otherwise he done what he is treatening to do. Wine spirit makes a person crazy, thats a logical explanation i could think of. Although he is intoxicated he paid the motorcycle he bumped while backing his BMW X5 of php 6,000.00. "Mukhang naisahan pa cya dito at tinaga pa cya dito sa presyo." Don`t know lang what is pissed him off to act that way..weird....
Just to increase traffic on my site i have posted the links..hit starts at 115,500 hits..let us see how many hits i would get from this link..

Hear it yourself...

Speed Up Firefox

Firefox is a powerful browser with extensions to do almost anything, but it's never been accused of being light on resources—and limiting your history size can help.

Every time your browser requests a page or image from anywhere, that data is stored in your browser history for a default of 90 days—for most of us that translates to an enormous amount of data stored in the internal history database. The Mac Tips and Tricks weblog has a quick and very useful tip to make Firefox load more quickly—just visit Preferences -> Privacy -> History and turn the dial down to a more reasonable 5-10 days. You'll need to clear your history or restart Firefox after you make this change, but in my testing the startup speed improved significantly.

If you want to keep your entire computer clean instead, you can set reader favorite CCleaner to run silently with a keyboard shortcut, or set it up to run on a schedule for hassle-free system cleaning—just make sure to include Firefox in your CCleaner profile.
