Step 4: Prepare The Flashlight

In this step, we'll be removing the white LED from the Hummer shake flashlight. By doing this, we will then be able to tap into the energy being created and stored in this circuit. Start up your soldering iron and grab your wire cutters.

Before I describe what to do, I just want to say that you have to be quite patient and gentle with this step. The circuit board you'll be working with isn't top quality, and you can easily tear the copper solder pads from the board if you push too hard or don't wait until the solder has liquefied. It can make things very difficult to work with if you manage to damage the board.

Alternate Step: By purchasing and using a solder sucker, removing the solder from the LED legs will be so much easier. But, it requires purchasing an extra tool from RadioShack. It's your choice whether you'd like to purchase the tool or not. It is quite useful if you plan on doing desoldering in the future.

RadioShack's Vacuum Desoldering Tool (Catalog #: 64-2098)

1. Start by pressing your soldering iron against one of the hard blobs of solder that hold the LED into place. Once the solder liquefies, take the tip of the soldering iron and use it to push one of the legs of the LED outward. Press the left one to the left and the right one to the right. (picture #1)
2. Use your wire cutters to snip the legs of the LED off and then pull the LED out from the top of the flashlight. (picture #2)
<p>I was actually searching for any instructable on a voice amplifier circuit, and I landed here. Could any one please provide me with a link for that..............it's urgent.</p>
Cool! it looks like a Jadoon Scanner!
ALL shake flashlights should be compatible, they may not have the same circuit board, but they should have a capacitor, a coil wrapped around a tube containing a magnet
Be careful when buying cheap "shake" flashlights. I have found some in stores that are fakes, they have a coil, but it's only a couple layers of windings, they have a plain steel slug instead of a magnet, they have no capacitor to charge and no diodes to rectify an AC voltage. They do have a white LED and two CR2032 batteries, so I thought it was still worth the $3 I paid at the time (have you priced those coin cells? They're expensive in the stores, at least $2 I think when I can get them for $0.30 or less at Digikey).
this is a very useful instructable i give it a 100/100
wow. very original i love it!
Any "shake" flashlight should. Or you could use one of those emergency crank flashlight radio combos and have a built in speaker and housing
Very Nice ! I really do like that you added the radio shack catalog numbers as a link
<strong>Very Cool</strong> I can't wait to make one for myself!<br/>
Quick unrelated question: How did you manage to get the flash player on to instructables?? I know I've tried several times but Instructables doesn't support HTML or embed's right?
I believe there is an Instructables floating around describing how to embed video using various online video sites. Since I have Dreamhost as my provider, I simply converted my video to a .flv and used their .swf player to embed it. I followed the instructions on how to embed a Blip as guidance.
Alright, thanks. I just asked this question here because I saw you used the same swf player I use. It's useful when you want to keep your stuff private if you store your flv files on a server; then you just have to link the player to the file. That way you don't have to upload it to YouTube, Metacafe, or others if you just wanna embed it. Thanks again.
hey that's cool! very nice pictures
Wow! That's really neat. About how much louder would you say it makes your voice?
It is a bit louder than your voice going in. Keep in mind that the project is very low power. But, I've noted a bunch of possible improvements to fix the volume and clarity in the very last step, "Improvements + Notes". For the time being, making an easy to build project using readily available electronic parts was my priority. All comments and ideas for improvement are totally welcome!
Amazing Instructable! Very detailed, the pictures are <em>GREAT</em>, everything is awesome, nice job labeling the items and stuff, great Instructable! +1 rating.<br/>
Great instructable! Well Documented!
