Plasma alarm clock?

I am thinking it might be fun to hack the speaker output on a digital alarm clock to somekind of plasma device that uses a flyback transformer. Something along the lines of a lightning alarm clock that was released a few years back.

Alarm clock mod

I took apart my alarm clock and took out the speaker and put in a headphone jack. Now it can wake me up and i was wondering if someone could help me figure out what the specific alarm electric thing looks like. I want it to be able to set off a motor that pulls off my sheets. I know absolutely nothing about circuit boards and things like that. any info would help. thanks

Hacking An Alarm Clock

My sister (yes, the one for whom I made earrings) wants me to modify an alarm clock to run a small electronic device when it goes off. Preliminary research has given me two methods:1) A digital clock with a 555 timer circuitIn this setup, a 555 timer circuit is used to translate the signal to an alarm speaker/piezo disk into a relay. When the clock goes off, the relay clicks, and any electrical device that is run through the relay has power.2) An analog clock with a transistor amplifierIn this version, the analog clock seems to just have a straight DC output to the alarm. The transistor is used to amplify the DC to drive the motor of a fire bell.Which of these would be easier to implement? The device I am supposed to use runs off of 3VDC, so I was just going to run the power line through the relay or through the transformer.

Customized Alarm Clock

What I want to do is this, -get rid of my alarms stupid sounds -insert a custom sound -do it cheap -and make it small enough I can still put it in a custom casing (the casing is the easy part, I'll have no issue making that.) I have looked around and have seen several ways to hack alarm clocks but I can't see how any of them would help me out with this particular problem. The way I see it I will probably need to rewire the clock so that it sends power to an external device when the speakers are supposed to go off. The only other way I can think of is having a small computer with one of those pre-programmed clocks but that would be more expensive than buying the sound recording clocks and a bigger pain to fit into the casing. I also think I heard someone talk about making homemade circuits, I don't know if that would work at all but it's worth mentioning. I would like to be able to find easy to follow instructions that are CLEAR and not super complicated. Any help would be appreciated! BTW, yes, I have looked at the sound recording clocks online and they all look like crap or are way to expensive to bother with.

Vibrating alarm clock help

 Hey guys,  I'm a soon-to-be college freshman and a very heavy sleeper. I contacted my soon-to-be roommate, and it turns out he's a very light sleeper and is frightened by waking up to loud noises. Of course, coming from a house where I used a phone hooked to a guitar amplifier as an alarm clock, I figured I'd have to change my waking habits. I heard from my father about an alarm clock system that utilizes pillow-mounted vibrators, but that costs waaaay too much, and I'm already going to have to balance a job or two just to get by paying tuition. Besides, I don't like buying things I can build at home. So here's my situation: I have a five-volt vibrating massager that plugs into USB ports that I wanna use as a pillow-mounted vibrator in college, so I don't wake my roomie up with a fright. My phone has a 3.5mm plug that I use to connect it to the guitar amplifier. My question is: How can I build an amplifying circuit that'll power the vibrating motor enough to work with the signal from the phone (or any alarm clock signal, for that matter)? I need 5 volts to power the motor. That much I know. I haven't measured the signal from the phone, since I haven't access to a volt-meter, at the time. HELP ME PLEASE!! Thanks.

An Alarm Clock Idea - No Lights, No Sound

I'm a pretty deep sleeper, and I don't wake up very fast in the mornings, which is bad since I ride the school bus to school. I set my alarm clock, with a high volume, but it still doesn't wake me very good. I've thought of trying to make an alarm that flashes a strobe light, something like a deaf person might use, but didn't think it would work very good. So, my idea now is to think of a way to make an alarm clock that gives pulsating shocks when it goes off. I have absolutely (well, 99%) no idea how to connect it up, nor how to produce the shocks. I'm thinking a shock with high voltage, but low current, like static electricity. I figure that should wake me. Do y'all have any ideas, or better suggestions? Also, do you think that the shocks (if usable) would cause any dangerous effects on my health? Thanks!

Binary Arduino Alarm Clock HELP!

I am currently working on THIS INSTRUCTABLE:https://www.instructables.com/id/Arduino-Binary-Alarm-Clock/ I have had to modify the libraries to work with IDE 1.0 and newer because this was written 5 years ago. I'm using a push button momentary switch instead of the capacitive sensor for the snooze button. I've got everything working except for the Alarm/snooze. For some reason, the speaker is constantly beeping a high, then low tone, as though the snooze button is being held down, even when I completely disconnect the snooze button from the clock. Can anyone give me any ideas how to fix this problem?

How to wire a light to an alarm clock?

Where I work during the summer I consistently have to switch between the day and night shifts. This happens every month or so and during the first week of transition I have a rather hard time waking up especially from transition from day to night shifts where I have to sleep during the day. Thus it is dark when I am supposed to wake up. Although I have not been late yet there have been quite a few "near-misses". Anyway I want to know if anyone can help me wire a light to my alarm clock to help this. My alarm clock alternates between a one second-ish noise to an equal length silence and repeats. I would like it to turn on and off in the same fashion as the alarm clock makes noise. I do not have much electrical know how, but I am adequate at soldering both wires and on boards. I have tested the output of the wires leading to the speakers and they do not have enough power to turn on the bulb. It would also be nice if can be done on a wallet friendly cost, college is eating up most of my money. Any help would be appreciated and thanks in advance!

D-Flip Flop and Clock Alarm

Hey there! I'm trying to hook up one Set Pin of a 74LS74 Double D-Flip Flop to the alarm of my clock. I've already desoldered the annoying buzzer thats been there before and am now measuring the voltage provided to the buzzer. Unfortunately the circuit only provides around 0.1-0.7V (crescendo alert) with each beep, which doesn't seem to be enough to raise the Set Pin to HIGH (0.8V min. I think). So I guess I'm supposed to use some kind of transistor now. Just to make sure I'm asking you guys. Also, if I want to run the clock from a 5V DC wall wart instead of the original 1.5V battery, I suppose the only thing I need to add are some resistors in series. Would that be correct or would there be anything else needed to ensure the clock takes no damage? Would be really nice if someone could help me out with this! Best regards, Philipp

RF Transmitting Shock Alarm Clock

I thought of an idea awhile back but I lack the "know how" to pull it off. I've been trying to teach myself some basic electrical and computer engineering but i'm still not learning what i need to know in order to finish my project. as stated in the Title, i'm trying to build an alarm clock that wakes up its subject with a jolt of electricity rather then noise, vibrations or anything else. the concept is to incorporate a miniaturized TENS unit (Transcutaneous electrical nerve stimulation) http://en.wikipedia.org/wiki/Transcutaneous_electrical_nerve_stimulation into an arm band or ankle bracelet sort of thing but comfortable. then when it is time to wake up the alarm clock then sends a signal to the arm/ankle band thus making it active. then to turn it off you would hit the off switch on the alarm clock not the band.  that is the extent of my crude invention, however i am having trouble with the transmitting part. what would i need to make this happen?? i was thinking of using an old car remote for some of the parts and using the overall idea of it in my alarm clock except i need a transmitter and receiver and i have NO idea how any of that works. thoughts? ideas? please let me know

Newbie here, I want to activate buttons on a remote control when my alarm clock goes off.

Hey everyone!  I'm pretty new to all of this stuff, but I'm interested in connecting my alarm clock to my Arduino Uno, and connecting my Arduino Uno to various buttons on the remote for a remote-controlled, color-changing, screw-in LED light bulb, so that when the alarm goes off, the Arduino activates a series of buttons, turning the light on in various colors. My initial questions are the following, I'm most likely gonna need follow-up help later. 1. How exactly should I connect my alarm clock to the Arduino? I assume that there is a current produced somewhere when the alarm goes off, how do I "tap into" that, and how do I get my Arduino to sense the current? 2. I'm thinking (correct me if I'm wrong) that I need to connect each remote button to a pin on my Arduino and then turn on whatever pin I want to change the light bulb color. Do I just connect them using wires, or do I need something else, like resistors or another component? If I do need something else, how do I figure out what specs I need to have in said component? If it helps, below are links to the light bulb I'm planning to get and the alarm clock I have.

Effective Way to Wake You Up

This alarm clock provides that: if you don't wake up, it will randomly dial someone from your cell phone's address book. An early morning call to your family, friends, or random person whose number you've got stored in there will guarantee that you have some awkward explaining to do.Link viaEngadget

So my concept is to rewire the alarm off switch for the clock so that I can use a wireless doorbell chime as a wireless snooze switch which I can place far away (that way I can't just turn it off and go back to sleep). I already cracked both of them open and took a look at the wiring. I'd just like some help to know which parts of the chime I can use as a trigger for the alarm clock. The clock i'm using has a push button for the snooze and a 4-way switch for the alarm on/off and settings. I figure it'll be a lot easier if I just tap into the snooze.
