Introduction: Vibrating Alarm Clock | Sugru

About: Innovative Projects, Diy's, Life Hacks

Alarm clocks have one big disadvantage. They are not designed to wake up only one person.

If you need to wake up, most likely you will also wake up your partner and sometimes even neighbours.

In this project we will be making a vibrating alarm clock/receiver.

We will need:

  • RC toy car
  • Alarm clock
  • Battery holder and “CR2032” 3V battery
  • Vibration motor (3v)
  • Velcro straps
  • Sugru
  • Small hindges (optional)
  • Some cables
  • Heat shrink tubing (optional)
  • Tools, Soldering iron etc.

Step 1:

  • Open your Rc toy car.
  • Check the voltage.
  • Take out the receiver.

  • Replace the battery with “CR2032” battery holder and battery.

(Your RC toy car might use different voltage)

  • Replace one of the motors (if more than one) with vibration motor.
  • Cut the original antenna, so it fits on the circuit board and solder it.

Everything should fit tight on the board.

Note:

If your battery holder and vibration motor does not have a sticky side, just use some hot glue to attach it to the board.

The battery holder I am using is actually from a bicycle led light.

Step 2:

Use “Sugru” to make a case for the receiver.

Attach some velcro straps to the sides and cover it with more “Sugru”.

At this point your creation should look like a watch.

Leave “Sugru” to dry before trying it out.

Step 3:

Open up the transmitter and soldier 2 cables to one of the switches.

Those cables will work as switch when joined.

Step 4:

Open up the alarm clock and take out everything that's on the way,

until you have a good access to the bottom cog.

You can also remove the speaker as you'll not need it.

Step 5:

On the bottom cog you will find a metal ring that looks like a “female symbol”.

When alarm function is activated, part of the metal ring (female symbol)

touches the contact on the board activating the alarm.

Disconnect the contact on the board from rest of the circuit. Use screwdriver to break the connection.

Then, disconnect the metal ring from the battery. I used a little cutter.

Step 6:

Solder a cable to the metal ring.

Solder another cable to the side of the contact you disconnected from the circuit.

Now your alarm function should work as an independent switch.

Step 7:

Join the transmitter with alarm clock. We used small hinges to do that.

Join the cables. We used heat shrink tubing for a neater look.

Step 8:

That's it.

Put on your “Sugru” receiver.

Set the time you want/need to wake up and go to sleep.

When alarm clock will activate, your “Sugru” receiver will start to vibrate.

Can't find your receiver?

Use the button on the transmitter to locate the receiver :)

    I'm gonna skip all steps, and just tie the alarm clock to my cat. That should wake up the whole house.

    If you have an old cell phone with a vibrate ringer, would that work as well?

    what if u take the alarm clock component, but u must take off the speaker than change it with that motor, then wrap it with ur sugru thingy

    Awesome Ible....

    Very creative. I used to set my cell phone to vibrate and put it under my pillow. Until I saw that they can start a fire when you do that. I have a "bed shaker" alarm clock now, which I use as a second or third alarm on days when it's really important to wake up (I am not a morning person) or to wake up my husband (who is deaf).

    This would also be great for someone who is deaf or hard of hearing, especially if they need to get up without disturbing their partner.

    Thanks

    The only downside is that it's not for everyone.

    It will not wake up a very heavy sleeper.

    I know a guy who is such a heavy sleeper, even shaking him dos not do a lot :)

    but isnt the watch looking for a signal for whole night? doesnt that drain battery fast?

    Not sure. I took out the battery as I am not planning to use it on daily bases.

    It's just one of those things I might use 2 x a year.

    if you are a heavy sleeper will this wake you up?

    That depends. Probably for some it will not work.
