I am a big believer in a greener way of life so I reduce reuse recycle and repurpose, to this end I gather many things put out for the garbage, the computers I get my wife likes to rebuild and gives them away to people that can’t afford a computer. The other things I get to repair repurpose or strip for parts.

In this Instructable I am going to repurpose a coffeemaker into a travel alarm clock, when I worked as a truck driver I had this travel alarm clock I bought in a truck stop for $20.oo. It was advertised not to use near a graveyard or it would wake the dead. I went through three of these alarm clocks they had the knack of growing legs and walking off.

I found the coffeemaker while I was helping my friend George make his deliveries, at first I wanted to use the clock circuit for testing LCD displays. Later that week I was visiting my brother and he mentioned he didn’t have an alarm clock and I got a new purpose for the clock circuit.

All the parts I used in this Instructable were salvaged but the battery I bought at the local dollar store making the total cost of construction one day and one dollar.

Step 1: The Coffeemaker

The coffeemaker was a Kenmore ADC coffeemaker; I plugged it in to make sure the clock worked.

Now that I knew the coffeemaker was working I dissembled the coffeemaker from the bottom up by removing all the screws from the base and then the components inside.

There are a few deep screws so you will need a long 12 inch Philips screwdriver.

I keep all the working parts that I may have a use for later.
<p>I have a clock that I pulled from a coffeemaker that had a burned up heating element. I'd like to make an alarm clock from it on AC power and attach a small strobe light to the alarm. (I'm hard of hearing and alarms loud enough for me can bother next door apartment neighbors.) Maybe a relay would be the best option, if I can find something with a repeat function that would make it flash at a safe rate. I wonder if anyone knows what a safe rate is, or where I can find this info?</p>
<p>An SCR might be better for turning on a strobe than a relay, but yea flashing speed has been known to induce seizures in people.</p><p>A vibrator might be more effective, you would be surprised at how effective a small movement can wake you.</p>
Inspiring, thanks! Any reason the relay couldn't turn on an AC radio? My clock radios dieing, and I have radios stashed away.
Should be no problem the buzzer went to +V and the switch was on the negative of the buzzer so a PNP transistor or a SCR should be able to turn the power on for a radio. <br> <br>Joe
I like that idea! I have three disassembled coffee maker s right now with no plans for them so I just might try this.
If you think of something different do an Instructable on it.
Wow!! very cool idea..I will try it for sure. Can we use a <a href="http://www.ultrasonic-sensor-manufacturer.com/" rel="nofollow"><strong>piezo buzzer</strong></a> to produce sound.
I used a Piezo buzzer with a built in buzzer and compared it to a feedback Piezo buzzer I built the driver for so yes you can use a Piezo buzzer. <br> <br>There is a down side the9 volt battery only works for a week so I upped the battery to a 6 volt aa battery pack for a longer life. Right now I am finding out how long it lasts. <br>
I've done similar with a couple of old Mr. Coffee models (the old LED style).. Yes, it's easy to convert the timers.. What irks me, is how much people just simply toss the maker, not even checking to see if the thermal fuse is the only thing blown.. But, their loss, my gain. :-) My version, I used to take a plastic box, and mount the clock through a cut rectangle, then mount a simple 2-prong AC outlet, then either a radio or a simple AC buzzer pulled from an old washing machine..
I&rsquo;ve been thinking about adding an AC power supply and a rechargeable battery to the clock, the 9 volt battery only lasts a week. <br> <br>It is very accurate and easy to use for that week though. <br> <br>Joe
very cool. ... I noticed you said you were a long-haul truck driver.... I was wondering if it'd be a cool idea to put a couple of resistors in line on one of those plugs that goes in the lighter socket in the truck. drop the 12 volts to 9 like the lil' battery puts out. then you could switch off as needed between the 9 volt battery and the lighter socket.
You could do a more reliable job with a LM78L09 voltage regulator since it runs on less than 20 ma, but yea it can be done.
Great job! But, the way travel is now, you couldn't go on flights with that, looks like a bomb timer or something peculiar.
I was a long hall truck driver
Very good recycling work, Josehf.
Right now I am seeing how long it runs on a 9 volt battery.
Very nice work :) lol i wish my alarm woke the dead...mine wakes *nobody!*
connect it to your smoke alarm
