Make a $5 Motion Sensitive Coca Cola Night Light

Coca-Cola Night Soap Dispenser

Here’s a simple project.

Motion Sensitive Soap Dispenser

Home Depot is currently selling this “Soap Brite Lighted Soap Dispenser” which acts as a night lite, lighting up the liquid soap with one of 7 colors when it senses motion.

It will set you back a grand total of $3.88 plus tax. The LED lighting is contained in the base and shines up through the plastic container to illuminate the soap. There’s a button on the base which can rotate through the seven colors.

Coca-Cola Bottle Replacement

By itself, and for the cost, the dispenser is pretty cool, but you can give it a simple upgrade by replacing the container with a one pint Mexican bottled glass coke bottle. I found mine at a local grocery store for $1. The dispenser’s container simply lifts off the base (no screws). The base fits the pint Coke bottle exactly. Find a pump that fits the Coke bottle, and it can continue its use as a soap dispenser (I was able to snatch one from another soap dispenser we had lying around which fit perfectly).

No pump ? Than simply put it on a shelf with the cap back on and you have an interesting night light!

Coca-Cola Night Light

Caution: If you are going to use the glass Coke bottle as a soap dispenser, be careful as it is a little top heavy and may fall if one is not careful when using. Suggest using superglue to glue the base. Not recommended for kids.

Easily Remove GPS Location from Photographs

GPS Mobile Phone

Your GPS Data is Stamped on Your Mobile Photos

Most cell phones nowadays stamp each digital photograph with the GPS coordinates of where the photo was taken. If you upload this to Google Photos, google will happily pinpoint the location on Google Maps with a click or two (and some applications may show this information when you view the photo). In addition the photograph will have other metadata such as camera make and model, etc. If you are going to share the photo with others or post it publicly, many times you don’t want this information, particularly, your location information, posted to the web.

Exiftool offers an easy and straightforward method of stripping metadata and is available for Windows, Mac, and Linux.

Backup Your Photos Before Stripping Meta Data

Make sure you have a backup of all of your original photos with all metadata before you start and only strip information from a copy of the photo (although by default it also makes a backup of the photo, adding “_original” to the extension).

Using Exiftool To Strip Meta-Data

  1. View All Meta Data in Photo

  2. On command line (in windows use CMD):

    This produces output like this:

  3. Remove Only the Location Information from Photo

  4. Remove Location Plus (caution, will strip other useful information)

  5. Adding an extra flag makes sure other xmp information that may contain gps location is also stripped. Unfortunately, this will also remove other information you may want to keep:

  6. Remove All Metadata from Photo

  7. Type the following

    Same photo as above, but with ll exif metadata information stripped, leaving only file and technical information:

Verify WhatsApp Without A Mobile Phone

WhatsApp

WhatsApp

  1. You Don’t Need To Provide A Mobile Number (but you do need to install the app)

    Whats App – Verify Without Using Your Cell Phone

    It’s common belief that you need to verify WhatsApp on a cell phone. When you install WhatsApp it requires you to give it a phone number and it then texts you a verification code. But in fact you can use a Google Voice number or have WhatsApp provide the verification by voice call, allowing you to use a landline. So if you don’t have a cell phone or one that doesn’t permit installation of apps, you can install WhatsApp on an Ipad or Tablet and use Google Voice or your landline to verify.

    Using a Landline to Verify WhatsApp

    1. Install WhatsApp on an Android Tablet (or a second Android or iPhone – you can’t install the full WhatsApp on an iPad)
    2. When it asks for a phone number give it your land line number.
    3. It will immediately attempt to send an sms text message to the number. This of course will fail. Below the number you will notice two selections “Resend” and  an option to permit verification by a voice call. These icons will be greyed out until the countdown timer next to them reaches zero.
    4. When the countdown reaches zero, and the voice call selection becomes available,click it.  The phone of the number you provided will ring with an automated call providing you the verification code.
  2. WhatsApp Device Is Required to Be Online for WhatsApp Web or WhatsApp Portal

  3. That is, you can’t install WhatsApp on your mobile phone, setup your WhatsApp account, and then uninstall WhatsApp and expect things to work. This is something you might do if you don’t want to install WhatsApp on your phone but want to use WhatsApp on the web ( or set up something like the Facebook Portal which uses WhatsApp to make video calls). Unfortunately it’s not going to work.
