		<description>It is possible to use the speaker signal for detecting the alarm signal. But you will have to read that input with the ADC because the speaker will have a lower level, probably not enough to be read as logical 1. This means changing the software. 
You will still need the rest of the signals (power, ac sync etc).
Do you want to turn on the speaker at the end of the sunrise?</description>

		<description>hi bogdan,

first of all i want to say THANK YOU for posting your project! :)
it is almost exactly what i was searching for.
but due to the fact that i am not that a profi in electronics like you are, i have one question:
is it possible to put this circuit directly before the sound device/speaker of an alarmclock? this would allow me to easily find the place where i have to put the circuit.
hope i described it good enough that you can understand what i mean ;)

have a nice evening!

		<description>Hello,

In treatment of SAD, we use relatively low intensity illumination (max 250 lux) over a 90 minute period (ending with wakeup time).

Nice project!

		<description>Thanks for the heads up. 
I was thinking of upgrading my system to two lights. The original 150W halogen will provide ambient room light and there will be a 50W halogen spot aimed at the place where my face should be. 
I want to upgrade the original clock to display time and temperature with a LED matrix and control the artificial sun light from the distance with the simplest solution, IR. This should provide a cost effective solution and allow some easy positioning of the two &quot;suns&quot; inside a room.</description>

		<description>Hey check this out:
hook up an IR led, automate your room:
set the hifi to a predefined volume/station/track, (maybe fade up the volume)
add any other IR scripts, TV, shades... to your awakening.

		<description>I always saw aquariums lit with fluorescent tubes, but those cannot be dimmed. You may only choose to turn them on or off. For this you need a different kind of circuit, do a search on &#039;dusk dawn circuit&#039;. 
You may also purchase these sensors at shops that sell stuff for your home or garden, as it is common for people to want certain lights to turn on at night. They usually have a sensitivity adjustment so you can choose how dark it gets before they turn the lights on.</description>

		<description>Hi,
Im trying to build a dimmer for my aquarium based on ambient light. Basically based on sunlight outside the lights should go off or go on.

I would like to discuss more on how the above can be modified to the same. Please do let me know.

Regards

		<description>Hi, Electro Bob! I really like your sunrise simulator. I hope to make one using a (1980&#039;s I think) Sony radio alarm clock, but like CaptMorgan I need it for 120V, 60Hz power instead of 220. Did you ever do that modification to your design? Or have I somehow missed it on your web page? Thanks very much for sharing this great plan! I&#039;ll appreciate any help you can offer to make the conversion to 120V, 60 Hz.</description>

		<description>I considered making a sunrise simulator too, only using 12V (perhaps car) lights. I bandoned that once suitable lamps came on the market. The Philips one I have is pretty terrible (as Philips things always are, but it was the only one back then) but it seems to work.</description>

		<description>There shouldn&#039;t be any problems connecting a heater, you just need a more powerful triac.
But i think that you might like to start it at full power just from the beginning, in this case you&#039;ll need to connect the switching element(triac/relay) to the signal coming from the clock which gives the start of the sunrise. 

Technical details aside, it&#039;s quite a great idea to warm up the room, but you might need a longer period than the sunrise to create a desirable effect.</description>

		<description>Ever try connecting a space heater to this as well? If you live in a cold place like I do, a warm room and a gentle light would do the trick!</description>

		<description>Whether you need to modify it or not will depend on the particular clock type you will use. THere is one major modification required: modifying the software for 60Hz which is your line frequency. That I can do for you, I will modify the software and post a 60Hz version soon. 
There is one other thing you will need to consider: the microcontroller works up to 5V only so you will need to find a regulated voltage somewhere inside the clock below that. I&#039;m not sure that all clocks will have this. 
Feel free to contact me for more help. 

Good luck building it!</description>

		<description>I really like your design and I&#039;m gonna give it a try.  I will be building this to use in the US so my line voltage for the lamp will be 120v instead of 220v as shown in your design.  Will the lower line voltage require any component substitutions?</description>

		<description>When I was in university, I&#039;ve already wanted to build a sunrise simulator. At this time I did not know how to control a 220&lt;abbr title=&quot;Volts&quot;&gt;V&lt;/abbr&gt; lamp &lt;i&gt;using a microcontroller&lt;/i&gt; but I kept it in mind. Having seen your tutorial I am one step closer to making it real again as soon as I have plenty of time. I appreciate the effort you put in creating this site.
