SAD sunrise clock, led bulb mod?

I suffer with SAD and a sunrise clock helps a lot getting up in the mornings and winding down at night. I have one similar to this It uses ses 14 bulbs, currently using halogen 42W but these don't last long and I managed to blow one closing a drawer! So, I'm looking for a way to use 10 to 20W leds  but obviously, given its UK mains voltage that does the timed dimming, finding a suitable LED driver is difficult. There are a few out there but I've no idea which ones will work as it need it to. Also, the only commercially available dimmable led bulbs are e27 fit only, very expensive and only 12W, around 400 lumens. I need at least 600. Also the more the better. Looking to use 6400K or higher colour, as the higher temp colours are proven to be better for SAD. I can make electronic circuits and have hacked together/repaired plenty of stuff. I would rather build something than buy as I don't have £££ to spend! Does anybody have any ideas to help me get started? I'm also looking to replace my SAD bulbs, currently 85W cfls with LEDS as well.

Chandelier sunrise alarm integrated in wall switch

Hello guys I found some nice instructables here about making a sunrise alarm clock, like the Philips wake-up alarm. I was wondering if it is possible (and how :D) to male a circuit with an lcd (maybe by reusing some cheap alarm clock) and put it inside the wall switch which operates the lamp in the chandelier by slowly increasing the light and reaching the full bright when the time is set to wake up! That would be awesome! Thanks for helping, Sam.

Sunrise lamp adaptor alarm

Hi guys and compliments for the comprehensive forum! I would love to have one of those sunrise simulator alarm clock out in the market but since I have no bedside table, and the wall cover with wood on one side, I am looking for a way to make an adaptor to start dimming my existing lamp at a precise time, like 7 am. I found out this product: http://windhovermfg.com/model/308  but the producer told me it does not work outside US (I'm from Italy) since we have 220V main and the gig would fry out. Also he told me it cannot be modified and power adapters don't work. Any idea on how to build one? Thanks a lot! Sam

Want to make a "BioBrite Sunrise Clock" (clock that wakes you by a gradually brightening light)

Hello, First message to this board. I have to wake up most mornings with sun still sleeping. I would like to try waking up with a gradually brightening light, rather than a jolt-inducing beeping sound from an alarm clock. I have seen http://www.foxnomad.com/2006/08/20/how-to-build-your-own-sunrise-alarm-clock, but I was wondering if we could add the "gradual-light" feature to his "instructable". PLease help. Also, please note that I am not usually one to use my hands to make stuff. I usually buy stuff  that I need and I usually don't fix stuff with my own hands. In short, I hope your instructable would be something a newbie can do.  Thank you so much.

Happy newyears

What did you do on new years eve / the AM's of new years day... I ran around the suburbs with my friends and my ipod+speakers, When it got too cold we would hang in train stations where we ate off vending machines, one of the vending machines was very very very evil, because they arranged it so infront of all the swedish fish there was a thing of potato chips, and infront of all the starburst was a rollo! We listened to lots of good music and watched the sunrise while trying to ice skate in a empty parking lot....Im posting this video because i played this song on loop forever while running up and down traintracks. Oh and what did you do on new years?

DC Motor Stop and reverse for a feeder

Hi, I attempting to design a feeder that will raise and lower an access door to where the feed is at. The door will open at dawn and close at dusk. I am trying to design a setup similar to an automatic car antenna. When enough light hits the photocell, the motor engages, travels a distance or hits resistance and stops. When light is no longer strong enough, the motor engages in the opposite direction and after the same distance or it meets resistance, stops again. Is this possible to do without Arduino as I am trying to keep this cheap? If so, what do I need and how can this be accomplished? The photocell is not a requirement as I have seen astro timers that can adjust for the changing sunset and sunrise times. Please help. I've got at least 20 hours of research into this and am hitting dead ends searching forums. A circuit drawing would be an awesome addition!!!!!!!!!!!!!!!! Thanks in advance

High Powered LED Lighting - Interfacing LED Driver with Microcontroller

Hello. I am pretty new to electronics but have slowly been getting my head around everything. I was hoping that someone may be able to give me some advice regarding circuit design. I am planning on constructing a high powered LED lighting system for my new marine aquarium. The high end LED units are still really expensive and so I thought I would construct my own for a lot cheaper. I understand the need for LED drivers to power these types of LEDs. But what I want to be able to do is control the brightness of the LEDs using a microcontroller to emulate sunrise/midday/sunset and of course moon light. But I am uncertain how you go about interfacing a LED driver to a microcontroller. Does anyone know of any useful tutorials or have any advice on how I go about completing this task? Thanks in advance, Steve

Do you live in East Bay?

Don't mind me - I'm just tapping all my resources :D I'm looking for a place to hang my hat in the East Bay area for the summer. I just need a place to sleep, cook a meal and park a car (and lock a bike) :) My goal is pack light for this trip. To be honest, I probably won't be around too much as I'll either be at work or exploring the area - this is my first adventure on the west coast (I'll miss those east coast ocean sunrises :P). I've been watching craigslist (more like waiting for replies :P) and I found the "420 compliant" person to be hilarious... But I'm not interested in being around it... So if you have an extra room (hell, even a camper - as long as I can take a shower somewhere) or anything - let me know. Or, if you know someone that may have a place - do share :) Feel free to ask any questions. If you prefer, my eMail is trebuchet03 at gmail dot com . Oh... and the hat I hang... it's a fedora - just because the top hat was too expensive.

Dawn

This poem is from my book Melodious Verse. It is a Carmen Figuratum of a sunrise on a fall morning I wrote while sitting on the shore of Lake Ontario 37 years ago. I did not have a camera with me so I did not capture an image of the dawn to go with the poem. I have photographed the dawn a thousand times and never captured just the right image of the dawn to accompany the poem. Carmen Figuratum a poem that has a certain shapes or pattern formed either by all the words it contains or just by certain ones therein. An example is the shape of each stanza resembles a wine cup.                                                             New Day                                     I sit watching god’s creatures of the night,                                      fleeing from the ever-approaching dawn.                                A bright orange and red haze caresses the horizon.                                                     Beyond this is the sun.                             Slowly ever so slowly rising above the edge of the earth:                                           to explode into an orange ball of fire.                              Sending a red-river of shimmering light across the water,                                                           now it is dawn.                           I can hear the cries of a seagull as it gracefully glides by me.                                               In the water ducks swim around,                                                 as the sun lights up the world.                                                       It becomes morning,                                                        it is dawn no more,                                                           but a new day.                                                                   By                                                    Josehf Lloyd Murchison                                             Copyright ©2007 Josehf Murchison

LED Reef tank light ( auto dimming)

I am in the process of redesigning a LED reef light using Luxeon III White and Royal Blue. These will let my coral grow the best. The biology of it I have down to a science... My circuitry however is still in its infancy. I have been following several of the instructables but i am at a point where I need some help... I can kind of get to the simple on off in my schematics (given I do not know what my power supply is yet) but as I read in Circuits-for-using-High-Power-LED , I now see that it can be a little more complicated if I want to preserve these slightly costly lights... So that leads to many questions from which most I might be able to get from the 12 books on electronics I purchased and borrowed, but something tells me that experienced people might have more practical solutions for me. What is needed to operate a 24 led array (Luxeon 3, Vf = 3.9V, 1000mA Each LED) from 115VAC to the DC? Now for a topic that I am having trouble with finding information to, back in the day I had an electronic ballast for a metal halide reef light that would fade on to full output over the course of 2 hours and would dim the same when turning off. this ballast had to cords on to supply constant power( i would assume) and the other to control the switch that would allow it to fade on and off.... I would like to simulate this sunrise sunset effect with my LED array? I appreciate your time and help with this project of mine.

How many hours of direct sunlight comes from north of the east west line?

We all know that the sun rises in the east and sets in the west.  And it is true 2 days a year!   The other 363 days it is untrue.  I found a neat little website sollumis.com that  gives a  visual representation  of the sunlight at any day of the year and at any location and  in summer quite a lot comes from the northeast and northwest in the mornings and evenings. (where I live at about 49 degrees north). I thought the rays represented 20 minutes of sun travel originally but now I am not so sure because the hours of daylight in a day do not correspond with the number of degrees of sunlight.  Does anybody know how fast the sun goes down? Does it appear to speed up as it goes down in summer or does it appear at its fastest around noon?  If it goes down faster than it goes at noon then there will be less hours of sun north of the east west line but if it goes slower, there will be more hours of sun north of that line. I would like to know how many hours of light  come from north of the east west line so that I can  give a guesstimate about how much more light my lean away greenhouse collects compared to a lean to.  The various websites are good for giving the sun up and sundown times and angles but none I have found give the corresponding times for the sun passing  the east west line in morning and evening. It is a tricky question and I can make a physical model to figure it out but maybe someone already knows the answer. In the diagram the sunrise is 5.11 am and sunset is 9.17 pm and the sun rises at 52 degrees and goes down at 308 degrees.  The degrees divided by 360 do not tally with the hours divided by 24  0.67 for the hours and 0,71 for the degrees. Thanks for any help Brian

Sci-Fi Gardening

I read an article on Dave's Garden a year ago on plants with Star Trek names, and I just adore the idea of having a science fiction themed garden.  Looking through some more plants, I've come across even more plants that would fit within a sci-fi/outer space theme. Coleus: Darth Vader Saturn Saturn's Rings Solar Flare Solar Shadow Solar Sunrise Vulcan Daylily: Alien Alien Contact Alien Encounter Alien Escape Pod Alien Invader Alien Landing Alien Skin Alien's Eye Android Android Dreams Andromeda Asteroid Astral Voyager Beam Me Up Beam Me Up, Scotty Ben Kirk Big Dipper Black Hole Borg Technology Cloaking Device First Officer's Log Galaxy Quest Klatuu Barata Nictu Life on Bajor Notify Ground Crew Photon Torpedo Romulan Deflector Spock's Ears Vulcan Logic Hosta:   Captain Kirk Enterprise Foxfire X Philes (just for fun) Galaxy Galaxy Light Gamma Ray Kiwi Milky Way Little Dipper Lunar Eclipse Lunar Orbit Lunar Sea Outer Space Saturn Starship Striker Super Nova Venus Voyager Vulcan These lists are not complete.  I looked through 5,320 daylily names out of 38,449 on Dave's Garden and then filled in with some names from the article, and I'm sure there are more genuses with sci-fi plants.  The reason why there are so many hostas, daylilies, and coleuses is because they're relatively easy to hybridize and propagate.  I started looking through African violets, but half-way through I was pretty sure I wouldn't find any.  I wouldn't be surprised if there were some more in the Liliaceae family such as with tulips, but phew, that's a lot of plants. Looking through some of the names, it would be relatively easy to do a Lord of the Rings or fantasy-themed garden.  I even found hostas called "Dot Com" and "Website".  Hybridizers certainly get creative when it comes to names.  I think I'll send my brother-in-law a hosta called "Twisted Sister". The image is of a basket plant I have.  No neat name, but it looks kinda sci-fi in the picture.

Sams Citizen Band Radio Manuals (1961) Free to download

My mate Gerry and myself are members of the Internet Archive, a vast depositary of out-of-copy-right texts, videos and audio. Volunteers like us, are constantly uploading new materiel, its all free to download, with some restrictions, like, "for non-commercial-use only". There are books like old telephone manuals, Bell Labs monthly journals, same for Kodak, books on building televisions from the 1940s, Radio, Electricity etc a book from Popular Mechanics, called "The Boy Mechanic", training manuals, and fiction. At last count, volunteers had uploaded 1.5 million text items. In the movie archive, there are training movies, and videos from the USA Government, on things like Nuclear Power and Subs, Power stations, ships,  a lot of stuff produced to screen in schools but still useful. Plus old movies, there is 22 episodes of the old Western Bonanza, for which the copyright owner forgot to renew the copyright on. Plus more like all of Edison made movies, 1900 and before, up to maybe 1905, then stuff like his gramophone, etc. Any material uploaded, that is under copyright, is quickly spotted by volunteers and reported for deletion. Gerry in New York, collects a lot of old books from library dumpsters, all of which he scans, and uploads to the Archive. and of cause most members upload, as you dont need to registrar at all, to download. Gerry just advised me, he is uploading some CB Radio manuals, I just checked, and its 5 volumes at least, of the following, on the following link. http://www.archive.org/details/Sams_Citizen_Band_Radio_Manual_Volume_1_ The 922Mb PDF is an archival version, so only download the 31Mb PDF, thats all you need to use the book. To review on-line, it the Read Online link, and the Text Only, has had OCR run over it by the Archive, so you can copy and paste the text, but beware, you need to proof read it for OCR errors. Gerry uploads a wide range of items, so he uses a keyword coding, to tie all similar items together on the archive, so when you reach the URL above, there is a listing of keys words, the one to click on is SP-000-001 which gets the other volumes as the other ones keywords are for linking to other members uploads to the archive. To see his other stuff, click on his name as publisher. (Publisher to the archive) or SP-000-001 for his similar stuff to the book below The following is Gerry's standard book description. BTW, Gerry works for a library, is a copyright expert, and even has a copy of a letter from Sams, saying the material is in the public domain, seems 5 years ago, somebody uploaded similar material to other website, was reported to Sams, the letter coming back, was then placed on the same website. Sams Photofact Series; Citizen Band Radio Manual, Volume 1; published in 1961. Published originally by Howard W. Sams & Co., of Indianapolis, Indiana. It was published under the Photofact folder series and is was copyrighted in 1961. There is no copyright renewal for this document so it is Public Domain under Rule 6 of the U.S. Copyright Statutes.

Album Review: Black Sabbath - Remastered Early Albums (1970-1973) ****-*****

Black Sabbath - Black Sabbath (1970)01 - Black Sabbath02 - The Wizard03 - Wall Of Sleep - Basically - NIB04 - Wicked World05 - Sleeping Village - Warning06 - Evil WomanBlack Sabbath - Paranoid (1970)01 - War Pigs - Luke's Wall02 - Paranoid03 - Planet Caravan04 - Iron Man05 - Electric Funeral06 - Hand Of Doom07 - Rat Salad08 - Fairies Wear BootsBlack Sabbath - Master of Reality (1971)01 - Sweet Leaf02 - After Forever03 - Embryo04 - Children Of The Grave05 - Orchid06 - Lord Of This World07 - Solitude08 - Into The VoidBlack Sabbath - Vol.4 (1972)01 - The Straightener02 - Tomorrows Dream03 - Changes04 - FX05 - Supernaut06 - Snowblind07 - Cornucopia08 - Laguna Sunrise09 - St. Vitus Dance10 - Under The Sun - Every Day Comes And GoesBlack Sabbath - Sabbath Bloody Sabbath (1973)01 - Sabbath Bloody Sabbath02 - A National Acrobat03 - Fluff04 - Sabbra Cadabra05 - Killing Yourself To Live06 - Who Are You07 - Looking For Today08 - Spiral Architect. Arguably the original Heavy Metal band, Black Sabbath - Ozzy Osbourne (vocals and harmonica), Tony Iommi (guitars), Bill Ward (drums and vocals), and Geezer Butler (bass) - brought death, drugs, occultism, and all sort of things your Mother doesn't want you to know about to Rock 'n' Roll with 1970's self-titled album (released, appropriately enough, on Friday the Thirteenth). Following quickly on its' heels was Paranoid, then Master Of Reality (with the stoners' anthem, "Sweet Leaf"), and Vol. 4. For Sabbath Bloody Sabbath, they brought keyboardist Rick Wakeman onboard.. With controversial lyrics and song lengths that regularly ran to five and six minutes or more, you weren't likely to hear much of them on the local Pop radio station (shortened versions of "Iron Man" and "Paranoid" managed to get a bit of mainstream airplay in 1972), but they were a staple for Album-Oriented Rock stations and 8-track players everywhere during the '70s. Almost every song here is on my medium- or heavy-rotation list (four or five stars).. I bought the original CD reissues back in the early '80s and was impressed at how much better they sounded than the vinyl/tape I was used to - not great, but definitely better. A friend recently loaned me a set of 320k MP3s from the remastered CDs issued in 2004 by Sanctuary UK. I really wasn't expecting much from the early '70s recordings (and it _is_ Heavy Metal), but thought it would be a good excuse to sit down and have another listen. Was I ever in for a treat! The remastered recordings remove a lot of the "mud" from the recordings and really bring out the instruments, especially the drums - "Children Of The Grave" really benefits from the remastering. The title cut from the self-titled album sounds even more evil (count the number of bell tolls in the intro). Can't really say that the vocals sound any better (or worse, it's still Ozzy at his best) and, at times, there is still enough hiss to be distracting, but overall I was very impressed with the quality.. I'll call these discs a Must Buy for all Black Sabbath fans who have the vinyl, tape, or original CD issues - I'm shopping for my set. Any of the first four CDs would make a great introduction to their music for Heavy Metal fans (1972's "We Sold Our Soul For Rock 'n' Roll" is a 14-cut (two LPs, originally) Best-Of collection that has also been remastered and might be a better choice, even if it doesn't include "Rat Salad"). IMNSHO, Wakeman, although great with Yes and on his own, really detracted from the Black Sabbath sound, so I can't recommend Sabbath Bloody Sabbath for new listeners. -- nacho
