What DC adapter does this clock use?

 Someone was throwing away this HoMedics ss-5000 alarm clock, and I "rescued" it. The DC adapter wasn't with it, though, so I want to find a replacement for it. (Without the adapter, it won't give any features besides the time and temperature.) Might any of you possibly have this clock and/or know what specs its adapter has?  Thanks,   Win Guy P.S. I'm sorry that the photos are sideways, the camera I used auto-flips images that are taken at an angle, and that was the only way that I could take the pictures without the flash coming back and glaring in the lens.  UPDATE! I found a really old variable voltage adapter, but it has a fixed amount of amperage: 300mA. In any case, today I'll open the clock and check the polarity. From there, it'll probably be smooth sailing. Thanks to everyone who responded to my post!  But this question is still open to people who have this clock who can tell me exactly what the specs are.

Pressure Washer? Answered

I would assume it can't be, but it would be really lucky if a pressure washer could fill an air tank to the pressure the washer is rated for.  So can a pressure washer that says 5000 psi really fill a tank to 5000 psi with the right fittings.  It probably won't be breathable or paint ball worthy but is it plausible.

How can I power a 5000 watt car amp without a car battery?

I've seen people power their amps with psu's but I feel like that wouldn't be able to handle this much power. I have a 2 farad capacitor that should take some of the load off, but in my car I run this thing with 4 and 0 gauge wire and my psu is nothing close to that.

How clouds act as an air pump to suck in air. Not how you think they do!

I have been thinking a long time about the biotic pump theory but I still don't understand it.  The math is too hard for me.   BUT it got me to thinking.   It is a point of major dispute in the meteorological world.   Does condensation cause low pressure?  2 russian nuclear physicists say yes,  almost everyone else says no!   So,  I thought and thought and thought.  Now I think I have a simple enough explanation And yes, they may not necessarily cause low pressure under the cloud (probably do)  but they definitely suck in air from elsewhere.  Imagine a fleet of huge doughnut shaped dirigible airships. They are sitting at 10,000 ft just floating there.   Now the commander tells everyone that they must now fly at 5000 ft.   So they turn on their propellers (in the hole in the doughnut) and drop down to 5000 ft by propelling air up  through the hole.   Now staying at 5000 ft is achieved by running the propellers at just fast enough.  So at 5000 ft they are pumping air from under the doughnuts to above them.   Now imagine a cumulus cloud.  Even though it is not fixed in size or shape and it does not have a propeller,  it is doing the exact same thing.  Air is being pumped up the middle and the clouds are sitting lower in the sky than they "should",  because they are sending that column of air up into the sky.   Here is my video to explain it visually.  https://www.youtube.com/watch?v=sPO8dWm_GIg

type of cement for building concrete benches?

The designs were pitted by aggregates I think.   I am wondering if a simple Portland cement with only sand would work? I also incorporate rebar as well?

What video card to buy? Answered

My old graphics cards died (two 8600 GT's in SLI), so now I need a replacement.  I've narrowed it down to either a GTX 260 or a Radeon 5000 series card, basically I can't decide whether Direct X 11 is worth it or not.  I've always been a fan of nVidia and I'd prefer to stick to their cards, but if I can get the same performance for the same amount of money with an ATI card w/ DX11 then I'd probably go with ATI.  My (original) price limit was $150, but since there isn't jack for that much, I've bumped it to $200.  I'd prefer not to go over that.  So how does the Radeon 5000 series compare to the GTX 200 series (within my price range)? Also, is DX11 worth it? My PC's specs: OCZ 550 Watt PSU (50 amps total on the 12v rails, 2 X 25A) Core 2 Duo E6850 Asus P5N-E SLI mobo 2 GiB DDR2 800 Mhz RAM 3 7200 RPM SATA drives The usual DVD drive A fairly crappy 16" CRT (1280x1024) Vielen Dank!

Sequential Loops for Pin Activation?

Hi, I am starting with Arduino and I am in need of some help. I am trying to sequentially activate 5 pins. I need each pin to be active for 20 seconds in a PWM manner. During their active period I want an arduino sensor to read out the signals emmited by each pin effector. So far I have no problems with the PWM or sensing module code. However I am not able to find how to correctly sequentially activate the pins. I used millis(), etc, but so far I was able to only activate / read the signals from the first pin effector. The sketch doesn´t proceed to the 2nd --- pins. I really very much appreciate your help....Here goes the code so far... const int greenPin = 11; const int redPin = 10; const int irPin = 5; const int bluePin = 6; const int yellowPin = 9; const int outputLDR = 12; const int ldrSensor = A0; int brightness = 0; int increment = 1; int readingoutputLDR = 0; void setup() {   pinMode(greenPin, OUTPUT);   pinMode(redPin, OUTPUT);   pinMode(irPin, OUTPUT);   pinMode(bluePin, OUTPUT);   pinMode(yellowPin, OUTPUT);   Serial.begin(9600);     setup_parallax(); } void loop() { digitalWrite(outputLDR, HIGH); readingoutputLDR = analogRead(ldrSensor); while (millis()<5000)                 {                                       if(brightness > 255)                    {                     increment = -1; // count down after reaching 255                    }                    else if(brightness < 1)                    {                    increment = 1; // count up after dropping back down to 0                    }                    brightness = brightness + increment;                                                        analogWrite(greenPin, brightness); digitalWrite(redPin, LOW); digitalWrite(irPin, LOW); digitalWrite(bluePin, LOW); digitalWrite(yellowPin, LOW);                    Serial.print("Reading Green"); parallax_output();                                     } delay(1); while (millis()<5000)                 {                                       if(brightness > 255)                    {                     increment = -1; // count down after reaching 255                    }                    else if(brightness < 1)                    {                    increment = 1; // count up after dropping back down to 0                    }                    brightness = brightness + increment;                    delay(1);                    digitalWrite(greenPin, LOW); analogWrite(redPin, brightness); digitalWrite(irPin, LOW); digitalWrite(bluePin, LOW); digitalWrite(yellowPin, LOW);                   Serial.print("Reading Red"); parallax_output();                                  }   while (millis()<5000)                 {                                       if(brightness > 255)                    {                     increment = -1; // count down after reaching 255                    }                    else if(brightness < 1)                    {                    increment = 1; // count up after dropping back down to 0                    }                    brightness = brightness + increment;                    delay(1);                    digitalWrite(greenPin, LOW); digitalWrite(redPin, LOW); analogWrite(irPin, brightness); digitalWrite(bluePin, LOW); digitalWrite(yellowPin, LOW);                     Serial.print("Reading IR"); parallax_output();                                  } while (millis()<5000)                 {                                       if(brightness > 255)                    {                     increment = -1; // count down after reaching 255                    }                    else if(brightness < 1)                    {                    increment = 1; // count up after dropping back down to 0                    }                    brightness = brightness + increment;                    delay(1);                    digitalWrite(greenPin, LOW); digitalWrite(redPin, LOW); digitalWrite(irPin, LOW); analogWrite(bluePin, brightness); digitalWrite(yellowPin, LOW);                    Serial.print("Reading Blue"); parallax_output();                                  } while (millis()<5000)                 {                                       if(brightness > 255)                    {                     increment = -1; // count down after reaching 255                    }                    else if(brightness < 1)                    {                    increment = 1; // count up after dropping back down to 0                    }                    brightness = brightness + increment;                    delay(1);                    digitalWrite(greenPin, LOW); digitalWrite(redPin, LOW); digitalWrite(irPin, LOW); digitalWrite(bluePin, LOW); analogWrite(yellowPin, brightness);                   Serial.print("Reading Yellow"); parallax_output();                                  } } void parallax_output() {                    Serial.print("DATA,DATE,TIME,");                                                                Serial.println(readingoutputLDR);                    } void setup_parallax() {     Serial.println("CLEARDATA");     Serial.println("LABEL,Date,Time,Green Response, Red Response, IR Response, Blue Response, Yellow Response"); }

Arduino heating controller: solar panel, oil burner, stove. NEED HELP AND ADVICE

HI this is my first time with arduino and electronics so please be forgiving.i want to make a controller for my home heating system and if it possible be able to control (change temp. setting, see statistic, etc. by phone - Bluetooth).so, i have three source of heat: solar panels (water), oil burner, wet stove. first part of plan is to connect all electrical components correctly (to make sure nothing blowup), second step is the program. third connect controller with phone by android or have a option to send sms to turn on/off oil burner.let's startthe heating system should looks like that (photo attach)please don't focus on the plumbing (that's only sketch), electronic and programing is more important.program (second step) should do:1. if T5 >T2 pomp P2 work 2. if T3>55'C , P3 work but only if O1 is switch off (automatically P1 and M1 is off, because they will be connect directly to O1 power) 3. option to on/off O1 by click on the phone (or by modul GSM in the future e.g sim800L) 4. additionally options 2 and 3 they are conditioned by other sub-option of 5 zones (where hot waterwill flow, so what will be heat): a)olny hot water in the tank- M3 open, b)only underfoor h.- M2 open, c)only radiators- M4 open, d) all heating, no tank- M2 i M3 open, e) all M2 M3 M4 open. so, before turn on O1 start making fire T3, one of the zone have to be pre-sellect.also if T1 >60st.C (and O1 and P3 are off), P4 will turn on (dump extra hot water to underfloor h.).that's all, nothing more .... but it's to much complicate for me right now. :smiley-confuse: and third part: all should be controll by simple phone app (android) e.g. turn on/off oil burner (maybe timer), change temp. in tank, change zone, see statistics etc.thera are elements what i have already- arduino nano-logging data module-relay 8 ports-bluetooth modul At-09, ble-4.0-extension board nano v3.0- temp. sensors DS18B20 i connect everything by all info what i've found in internet. also i tried to do simulation in THINKERCAD but many of my elements are not exist in the program, stiil no win. i didnt want to connect power just in case of blow off :o this is what i already found online:http://www.reuk.co.uk/wordpress/arduino-solar-water-heating-pump-controller-design-and-code/https://thesolaruniverse.wordpress.com/2016/11/21/monitoring-temperatures-in-floor-heating-loops-with-an-arduino-with-data-display-on-a-3-5-tft-screen/http://house4u.com.ua/articles/solar-controller/en/part11.phphttps://www.instructables.com/id/2nd-Gen-Arduino-Hot-Water-Solar-Collector-Controll/https://forum.arduino.cc/index.php?topic=70048.0and about bluetoothhttps://arduino.stackexchange.com/questions/19517/hc-05-bluetooth-module-inq-command-doesnt-worki only showing the links to proof my hour's spend in google.i think first two are the best.so i put together all what i found and this is my first program:const int TANKSENSORT1 = A0;

Has anyone else thought of getting their hands on a free boat, buying some cheap land (It's apparently not hard to get 5 acres in deserty parts of America for $5000 or even less) and burying the boat in the ground up to the waterline? You could use solar for power, and if your boat was a sailboat, you could probably rig a windmill to the mast to generate more electricity. Any thoughts on the practicality of doing this? Could you just dig a hole and bury the boat, or would it need some sort of framework to support it properly? Would transporting the boat to your land be too expensive to be worth it?

Knex ball machine.

I was wondering if somebody could make a new knex ball machine, with 4 paths, and with 3000 - 5000 pieces. what you can use: any connectors or rods anything from the big ball air tower set any gears any motor what you cant use: orange tubing over 10ft of chains (unless its some kind of other lift) these are other ball machines i made. i broke them because there were not many paths, the ball kept falling off, or that they just werent good enough. project box project immeuble project nano project dos project aggresor (the famous knex big ball factory below)

Open page in new tab, not working

When I am writing or editing an instructables I usually put in some links, when entering the link I get a option to "Open page in new tab", The only issue is that when I enable and save that option the link opens in the same page and then the box is unticked when editing it again. I have included a short video about this Here https://youtu.be/OHCSXtDeIkk SYSTEM: MacBook Air (Mid 2013) MacOS 10.12.3 (Beta 16D17a) 1.3GHz i5 2 cores with hypertreading 4GB 1600 MHz DDR3 Intel HD Graphics 5000 BROWSER: Safari 10.0.3 (12602.4.3)

Need help finding a certain project

I am on the Instructables email list, and there was a project that was on an email earlier this year.  I really wanted to do it with my kids, and I got the items I needed: ON/OFF Switch With Cover 4x 1.5V AA Battery Holder Battery Case Battery Box with 5.5" Black Red Wire Leads and 5000 RPM 6V High Torque Cylinder Magnetic Electric Mini DC Motor But I have FORGOTTEN what the project was, and I no longer have the email!  I do know that I ordered the items above on May 21st, so the project had to be in an email on that day or a bit earlier. I’d really like to make whatever it was with my kids… can anyone help me?

How much and how efficiently can a capacitor store charge?

I recently found out all the items required to build this project: https://www.instructables.com/id/Electricity-Generating-Footwear/ .  I don't want to buy the power bank, so I though about using rechargeable batteries. But I had none, but I had capacitors and I thought of using them.  These capacitors 1000 uf . I am thinking about soldering 5 of them in paralell so that I have 5000 uf storage capacity, But I am concerned how well it would work, if at all.   Can this store upto the amount of charge that a powerbank can? Can it actually charge up at a constant voltage if I use it?  Thanks for helping!

How to test the power output on a wind turbine?

I'm on a team prototyping a water filtration system powered by a Savonius wind turbine; the energy from the spinning turbine is mechanically transferred to a reverse osmosis filter/pump setup. We're doing tests of various blade configurations and are trying to determine the power output by hooking up a small DC motor (1-3V, 5000+ RPM) to the shaft. We're seeing only mW outputs though and were expecting something significantly larger. How do we pick a motor for the job? Do we need to match the RPMs of the motor to the expected RPMs of the shaft (~150)? Any other ideas for testing power? Thanks for any help!

World Clock Project

The World Clock Project takes a creative look at time. By taking clocks from around the world they're mixing time-zones and still keeping a relative view. It's thought provocative to think about time and how important it is to the human experience. Time is our most valuable currency, it's really the only thing we have. So it's interesting to see how important keeping track of it has been, we've been using Obelisks as sundials for over 5000 years, some of the most ancient artifacts from egypt were built to keep track of time.It's good to see that The World Clock Project is keeping time on our minds. Give it a shot, upload your clock and let us know where it is[http://world clock project upload http://worldclockproject.org/]-bg

This is what happens when you're on the frontpage

Here are graphs of the stats of two of my instructables. They clearly shows that being on the frontpage or featured in the weekly newsletter really gives you a boost.The Marble Clock (the graph with 0-5000 as the scale for pageviews) got in the frontpage as Popular in the afternoon the 14'th, you can clearly see the rate increase of pageviews.The Spooky Led Lamp (the graph with 0-10000 as the scale for pagevews) made it to the Weekly Newsletter sent to the subscribers in the eventing the 14'th. As can be seen on the graph the numbers of pageviews increased really fast at the next few hours then went back to the normal pace again. In contrast to what happened with the Marble Clock this instructable also got a real boost in the ratings due to the newsletter.Here's a link to the Instrugraph Instructable.

OFF GRID POWER Systems MSW invewrters Answered

Hi, Recently I purchase a 5000 watt 60cycle, 24vdc to 220vac inverter (MSW) to run my off grid cottage on, when I received it it had a 2 wire out put. could I conect the inverter 220v out to a 220 to 119/220v transformer  so i  could connect it to my north american house hold elecrical panel?? This would give me the 220v split single phase (full sinewave) similar to hydro power?? Our cottage maximum wattage reguired at any one time we only reguire 12-1500 watts as we have propane stove, fridge, furnass,and hot water. Therefore we only need power for vacum cleaner, washing machine, microwave oven and Led lighting. regards ron

Reduced views

I am feeling a little foolish while writing this, but I have noticed that the views per instructables has reduced remarkably. Earlier the instructables featured on the homepage had around 5000-7000 views in a single day and now that number has reduced to 500-1000. for example- https://www.instructables.com/id/Sustainable-Geometry/ https://www.instructables.com/id/Live-Instructables-Followers-Counter/ https://www.instructables.com/id/Wooden-USB-stick/ and i would like to add that these instructables are Fabulous. Not only this, the views on a normal featured instructables has also reduced. Is it because of that, that too many Instructables are being featured? I don't know, but I think something needs to be done to address this issue.. If you agree or disagree please leave your valuable suggestion.   Credits: Wooden USB-stick by X-plain,  Live Instructables Followers Counter by Nikus,  Sustainable Geometry by ENGL212.

How do i plug a leak on the bottom of my 5,000 gallon well water tank? Help!? Answered

I can patch the side leaks on me metal tank easy enough with marine epoxy. but there's no way i can crawl in the tank without destroying the bottom with my weight. i would like to find something i can pour in there that would sink and find the hole and cover it up. wouldn't take much with the water pressing against it. maybe some sort of saw dust? it would eventually sink and find the leak? but it can't rot over time or have bad chemicals in it...  or something made of much smaller particles? really needs to be a remedy tested by time, maybe something from our grandfather's day. or, i could make a remote controlled robot with manipulators and a camera! nahhhhhh..... thanks

Wanting to put red LEDs in the hood scoop of a truck so it looks as if the engine is "alive." Answered

I have a friend who wants to put red LEDs in the hood scoop of his truck. The truck is a Toyota Tacoma with a stock hood scoop. We want to have the system run so that the more RPM the engine experiences, the brighter the lights shine. There would be a baseline brightness (idling RPM) and a maximum brightness (4000-5000 RPM) Revving the engine would make the lights go from dim to bright and them back to dim when you let off the accelerator. What materials do we need? We don't want to make a flashlight type light with the LEDs but more of a glow. Are there certain LEDs that would be better suited for this sort of application than others? What kind of switch/wiring could we use? Many thanks -Livingstrong

How should I make a webcam as a door camera and use it

I have a TV of aiwa model A1419 from past 25 yrs at home which I have not been using it since past 1-2 years and have not even started it because I bought a plasma TV 2 yrs back but my old TV even works fine till date if cable is plugged in. Now since I have this TV lying around and I also got a Lifecam Show & Lifecam HD 5000 webcams lying around I want to make a better use of it. So I would like to know how can I make them work as a security camera's outside my house door and watch anyone who comes at my door on the TV itself. The distance between my house door and the TV would be of at least 5-6 meters.

HELP, I NEED / desperately want A SUPER BRIGHT FLASHLIGHT for camping / boy-scouts [answered]

Inappropriate Incomplete Spam first thing first, i want absolutely the BRIGHTEST flashlight i can my hands on! how many lumen's should i shoot for (to impress others)? 100, 270, 350, 600, 900, 1500, 3600, 5000+ (5000 Lm i pretty sure is overkill)? i have an led flashlight i got for 12$ and is advertised to be over 600 Lm but I'm pretty sure its maximum is 70Lm. (it seems to be slightly brighter than the 9 LED tactical flashlight i had) but I'm not sure. i have no light meter. the LED itself is (as advertised) is CREE (i don't believe that either but again, I'm not sure).   i would like to make portable HID flashlight. my plans are to: BUY: 6V LANTERN HID KIT (BULBS) HID BALLAST 12V BATTERY (I"m not sure where i could find a suitable 12-15V 35W [or more] battery that will fit nice and snug in the lantern with room for the ballast. the battery should last almost a week with some moderate use.) i think a drill battery would work. i will take the original light out and replace it with the HID. then, i will need to find a place for the slim ballast [but where???] . then,i need to find a battery (i think a 12V drill battery should work [will a 14.4V drill battery with the case off fit in the modified 6V lantern flashlight? if so, where can i buy a affordable and well suited 12V-16V battery?] if there isn't any small, powerful (and preferably cheap), battery in existence? [4 by 4 by 2 array of AA rechargeable batteries seems promising and so does 6^2 by 2 array seem promising. 6 by 6 by 2 AAA] will the ballast and lamp work with less power (6W-34W)? is there a simple and small ballast circuit schematic i can follow? i never found one. so i assume no. :-( also is the 5000K neutral white, warm or cool? (i think it is the closest to neutral white with a VARY slight blueish tint) i think i got a grasb on this and i want 6000K (i want something led white but still bright and useful enough to easly see what i'm doing on campouts)

NGOs I can approach for sponsorship, regarding my solar project?

As I mentioned in the post for the Sunflower, I'm going to b spending the next year or two traveling around teaching people and communities how to generate and integrate solar energy into their local needs, pretty much for free. I've got a bit of money saved to pay for this if necessary, but was ideally hoping to get some kind of grant or sponsorship just to cover my cost of living, which would probabaly come to about £5000 / US$8000 over two years. I have a very low cost of living. Does anyone know of any NGOs / charities / etc I could approach for this? I'm not really needing or offering anything other than the cash to cover my expenses. I can name drop and put a logo on my website and all that, they wouldn't need to really do much of anything other than sling me the cash, safe in the knowledge that they were instrumental in bringing free solar energy to anyone who wants it. Cheers, Daniel.

Darex and SRD Drill Grinders

I have an older Darex E-90 Drill Sharpener. We don't have anyone to run the machine, so we're getting rid of it and we don't want to store it! If you have a machine shop or just go through a lot of drill bits this could be a handy tool. It runs well and comes with a few accesories. New, these machines cost a little over $3000. Asking $1000 obo. I also have a SRD grinder. It's not as nice as the Darex one, but it too needs to find a new home because we don't use it. I think it's an 80-M, but it could be the 82-R Brand new the 80-M starts at a little over $1000. Here is the details from the tag: Type: NSE-34 No: D1301306 Volts: 115 Amp: 1.7 Hz: 60/pc Hp: 1/8 RPM: 5000 Duty: INT Ins: A C amb: 40 C Asking $400 obo for that one. They are located in Kent, WA if you want to come get them. We can ship UPS as well. $1200 for both if you really want two. Thanks~
