Custom Power Supply for Lemax Products

Curious if it would be possible to make a custom power supply for the Lemax Halloween town.  We end up with a tangle of wires every year, and I saw recently This on Amazon and thought it might work.  The only problem I run into is that the bigger Lemax products (houses and spot lights) use 4.5v where as the smaller figurines use 3v.  I've seen a lot of computer PSUs used for benchtop power supplies but none have a 3v or a 4.5v output.  I'm fairly competent with electronics, so I understand this might be more difficult than it's worth.

Why isn't plastic used in the construction of houses? Answered

If plastic can be customize to our needs, why can't plastic be customized to be non flammable, UV resistant, non toxic and thermally insulated to be used in house and bulding constructions? Petroleum based plastics are non biodegradable and would last for hundreds of years. Any reason why we do not see more houses built with this versatile product?

Hair gel? cleaning products? What can you do with it?

I have several jars of hair gel which I used once upon a time but I want to find other uses for it . I did hear that you can make it into a paste for putting onto the surface of vinyl records and when it sets you peel it off and it removes fine dust without scratching. Any ideas would be appreciated.

Mozzies and how to keep them outside....

Down here the winter was too short and not cold enough, meaning insect life is literally exploding in numbers already. The house I moved in has badly installed flyscreens on the doors and windows, most likely due to the fact that the house is moving up and down in several points... Anyway, due to the gaps everywhere I found myself with the problem that the mozzies covered my entire front and back door areas. With an unsupporting landlord not even allowing me to replace the bad flysreens with proper ones at my cost I was left with less invasive options to tackle the problem. Before you ask: No I am not even allowed to fix holes in the flyscreens covering the windows :( My next step was to check the local garden center for some natural solutions. Lemon grass seems to do the trick for the inside, the smell also keeps flies away really good. But I had to put the pots in the garden as the ongoing smell gives me headaches. It also did very little to prevent the mozzies from coming inside when I opened any outside door for a few moments. Only way out was to get rid of the mozzie population having daily meeting around my doors. At the local hardware store I found several "surface sprays" and they all stated to be very effective against cockroaches, spiders and other crawling insects - too bad I don't have a problem with them LOL After asking I was informed that those sprays do little to nothing for flying insects, including mozzies and that I would waste my money. During my next shopping trip I got desperate and grabbed a can of surface spray from Aldi. Was under 3 bucks, so I had nothing to loose compared to the 40-80 bucks for a canister of "the good stuff" from the hardware store. At the checkout an old lady asked if I moved into a new house with cockroaches when she saw the spray and I said that I only have a problem with mozzies. She recommended to eat more bananas ROFL Back home it was already too sunny at the front door for the mozzies to show up so I waited till the late afternoon and sure enough I found the area covered with them again. The spray annoyed them badly but I kept spraying all cracks, surfaces and also the gaps at the roof line. Kept checking for a while but could not see any real effect on the mozzies other than swarming around me and trying to suck my blood. Next morning I found the floor at the door covered by a carpet of dead mozzies! I don't mean a few, I am talking enough to take the brrom to clear them up :) Now for the past 5 days the body count is going down quite fast while my door stays free of mozzies. Still have them flying around in "normal" numbers but I can get in and out without a swarm of them following me. Since the product is plant based and considered to be without any side effects on humans or pets I will see how long it lasts and then just spray again - this three dollar can should last throughout the summer... You might wonder why I go through all these troubles... Long story short, I am quite allergic to the bites. Happened as a kid when during a warm summer night at a friends place I got so many bites that the doc gave up counting. He reached over 200 just by counting my head and face to the shoulders... Now I am allergic to the bites, the itch lasts over a week and thebite area swells up to the size of a 50 cent coin with blisters forming after 2 days. You might not get it hat bad but if you do suffer from the bites I found two remedies that help with the itch and reaction: a)  BBQ igniter (the manual push type without batteries)! They work like the expensive clickers you get at the pharmacy but last much longer - plus they require more force. The rounded tip is placed directly onto the bite and when you push the button in to "get shocked" two things happen. First the pressure forces the soliver that causes the reaction into deeper skin layers where there are less receptors for the itch. Secondly the high voltage breaks down certain parts of the soliver making it far less effective to cause harm. Downside is that you might like the shock in certain areas and that you should shock at least 10 to 15 times to get a real benefit from it. b)  Hydrogen Peroxide (3%) You put a drop of H2O2 directly onto the bite or for difficult areas use a soaked cotton bud. Rubbing it in with a cotton bud for a minute or two works best IMHO. You might see your skin turn white or feel a slight burn right where the bite is - that is normal and harmless. The hydrogen peroxide releases oxygen into the skin - this turns the skin white for short period of time. But the oxygen also breaks down the soliver and the byproducts of the body reaction to it. Works great for horse fly bites too. Downside here is that you should not overdo things and that you should test first how sensitive you are to the reaction. A good test is to apply it onto a small cut or scratch to clean it. If you tolerate that then won't even feel it on a mozzie bite. I hope some of this will help you through the summer ;)

Has anyone used Rustguy or zero-rust converter products?

I am looking for a fast and easy product for my volunteers to use on a steam engine that is being restored and wondered if these products are any good and worth the $$$ they charge? These products seem to be an improvement over the gloping on of the Naval Jelly and hundreds of man hours of wire brushing and sanding, priming and painting... Just wanted to know from an outside source if these are good and effective so I can recommend them to the Board of Directors and not end up looking like a jerk... They already think I don't know much because I'm younger and a girl! For example, I am still trying to convince them that the engines on static display would look nicer for longer if they used an epoxy based paint instead of exterior house paint! I appreciate any thoughts you have on the two products listed, if you know anything about them! Thanks!

Tips or products you recommend for clearing or preventing ice in winter?

My partner and I just bought a house and we're doing some repairs and upgrades. One of the major things I want to focus on is making our front entrance less icy. Most of the time we're covered in snow, but whenever it warms up briefly we end up with an icy disaster on the front porch the next morning. :P Currently, the roof melt runs right off onto our front steps and it's a mess! (see picture for the icicle death trap)I have been using a "pet-safe" ice melt (we have two dogs who are in and out all day) but it doesn't do enough for how much I go through. I still break up the ice in the morning when using the ice melt because the ice builds up really quickly.Are there gutters strong enough to handle heavy snowfall? Some sort of heating element I could install? For reference, I'm in northern CO in the mountains and we tend to get feet of snowfall every winter! I've never lived somewhere with this much snow, but I'm hoping some of you do and can offer some suggestions :D

Warning Light for Gas Grill

I get a text yesterday "Hi Dad, Are you going to be home soon? I left the house and forgot to turn off the grill." The grill is in the back yard, a few feet from the kitchen window. The grill connects directly to the house gas supply, so it will never run out of gas. I have found the grill on days after someone finished cooking. So far, we haven't burned down the house! I am searching for a product that would put a large blinking light on the kitchen window. It blinks when the grill is hot. It would remind me and my family to turn the grill off. Anyone know of a product that I could buy to do this? Seems like a natural Arduino project, I'm just short of time now to make it. Thanks, in advance. -Frank

Hi All, My thought was this, I live in New England and of course there is a lot of snow and ice in the winter.  I am going to have an exterior stair that leads to the third floor of my house and keeping them snow and ice free in the winter will be  a major PITA!  I have looked at a lot of different heating products but none seem optimal.  I was thinking, after remembering small heating elements, similar to the coil you could just put into a glass of water to heat it, why couldn't I just turn the steps into a low temp heating element powered from the house's electricity? Is this totally absurd or should it be possible?  Any ides? TIA, Aaron

How can a LED be flashed like a strobe, motion activated and installed outside to act as a security light?

This is about home security.  I have posted another security question on single LEDs in the same category. We have a remote house under construction at the end of a cul-de-sac.  My idea was to create some type of motion-activated single flash strobe or LED burst of light.  This light would be installed at the cul-de-sac and the motion sensor could be further away.  I just want to create this big flash so that any one coming around in the wee hours has to decide if they just had their picture taken and do they want to go further.  The strobe would just flash once like a camera flash, not flashing repetitively. So the final product would have to be weather and water proof.  The house is about 200' from the cul-de-sac but there are a number of empty, underground PVC conduits run from the house electrical panel which could be used to run out 120v or low voltage wiring. I've looked everywhere on the net.  The closest I could find were cameras that are made to take flash photos of animals at night and are motion activated.

How do you clean a dish washer?

I was wondering can any one give me pointers on this? Lately our dish washer is leaving spots on our dishes, glasses and est. I figure it is a build up of minerals in the spray and drainage holes of our poor dish washer since our house water system does have hard water. Even though we regularly use things like Jet dry to supplement the dish washing there comes a time where even that is not good enough to keep away crusty minerals. We had this dish washer for years now and never have issues until now. I plan on using a product like CLR in the dish washer but I'm not sure what to do next. Do I just pour the whole bottle of the product in the machine or do you pour it in a certain place? After I do imagine that I would have to let it sit in there and then run a few cycles? What do you guys suggest? Thanks for your input.  :)

Ponoko - personal manufacturing platform

I was lucky enough to have David and Derek from Ponoko over to my house for Thanksgiving (all the way from New Zealand!). Ponoko is a personal manufacturing business, and is something I've been dreaming about for years. You can design a product, have it custom built using precision machines, like laser cutters, and if lots of people like it, they can buy it too. If you don't have access to a laser cutter, this is one of the best ways to see what you can do and try one out. For inspiration, you can check out How to make a laser cut lamp, which I encouraged them to post. It not only shows a cool lamp, but goes through the design process and using Ponoko's service.So, check out their service and tell us what you think. The Ponoko guys are here on Instructables, and would love to hear your feedback.

individually addressable led DECORA switch

Greetings collective Instructables genius, Here's the deal, I have a kitchen,  I also have several strips of individually addressable LED's powered by the same supply.  I like the led's, I really the fade between teal and blue as it gives the impression that you're underwater.  At any rate, having anything other than a decora sized switch is out of the question.  I don't need another remote, or some box with switches on it to control the LEDs.  I'd really like a switch that can be mounted in a single gang electrical box, that can be covered by a decora faceplate.  I have a media cabinet where the power supply for the LED's is housed, and the switch can run to the supply in the cabinet.  I need at least 4 programs (like the underwater effect), though 8 would be ideal.  Any thoughts on how to approach this?  I'd spend upwards of $80 for a finished product.   Any input is appreciated.  Thank you Eric

Can I cut the end of a computer keyboard power cord and connect a USB cord to it?

I just got into electronics and I really like LEDs. I started looking around the house for some, but I might just go buy brand new ones. Well, I still have my old computer and I took apart the keyboard for LEDs. Instead of trying to take the LEDs out of it, I decided to keep everything together. The power cord is connected to the other board thing (a motherboard or baseboard?) It is one of the kind that have the 6 long pieces that makes a circle-like shape. I want to know if I can make that end a USB. www.quarkr.com/app/upload/product/20090525/image(962).jpg I see that in this image this is something that I want to do. But everything from the keyboard is still connected. I hope I am explaining this clearly enough.

I want to hardwire an LED kit with switch to the household wiring?

I've found similar instructions online but not quite the same thing I'm wanting to do.  Essentially, I want another fixture in the bathroom without using the plugins. I have an LED kit with switch included.  (http://www.amazon.com/gp/product/B00UL2KKBQ?psc=1&redirect;=true&ref;_=ox_sc_act_title_1∣=A3QAWKW1O2SEC3) I want to put the LED strip lighting under the bathroom sink vanity for subtle lighting in the middle of the night.  I want to set up the on-off switch at floor level to be poked with a toe.  However, I do not want to have a wire running from under the cabinet, across the wall to the plugin. Is there a way to hardwire this LED kit into the house wiring that is already present?  NOT where an old fixture was, this will be all new wiring.  Thank you. Even sources that might help me would be appreciated.

Project for vector calculus

Hello there, So, for my project in Vector Calculus: The suggestion is that we pick a certain "curve" within a country road. We are to log longitude, latitude and altitude while we drive this "curve" for approximately 15-20 seconds. With the data from the latitude-longitude-altitude "logger", we are to perform the various vector calculus principles we have learned in class. Instead of driving the road, I would like to attach whatever latitude-longitude-altitude logger to a boomerang, and get my curve through flight. Does anyone know which sensor I should be looking for? A bit about me: I am currently an electrical engineering technician in product development for a motor-controls company. I mostly test hardware/software, which is designed by our in-house engineers. I am very comfortable with soldering, visual inspection of PCBs, schematics, and general electrical engineering knowledge. Does anyone have a feasible idea for getting a gps unit onto a boomerang, and be ale to transmit the data to me in real-time? Thanks in advance.

3 way light switch push button, working at low voltage controlling line V light

I'm adding an additional light to a room with 2 entrances in an old house. Instead of using the common 120V 3-way SPDT switches to control the light fixture from 2 points, I'd like to use a relay (or something electronic) directly connected to the load of the light, and I'd like to run low voltage wires to push buttons located near the doors of the room. These will control the light by one press = on (if the light is already off), and the following press will = the alternate condition, the light going off. IOW, the push-button will toggle the on/off condition.  There should be a commercially available relay (some kind of latching relay, perhaps) product with the circuit. Can anybody recommend something? Or, perhaps I could put together the components myself. Does anybody have a schematic of something along these lines?

brainstorming a controlled temp kiln for polymer clays?

I am making some highly  detailed prototypes, and Im using polymer clay for the details. I've been baking them in my kitchen oven, but it's starting to get hot with summer coming on... I want to limit the heat production in my house! I have an old toaster oven, but it's too small for my items. I was thinking of taking it apart, and using the heating elements and temp controls in something a little bit larger. I'm wondering what the community thinks about that? My temperature needs to be 275° for fifteen minutes at a time. Some temp fluctuation is okay. I'm thinking 14 inches cubed would be plenty of room for my largest pieces.  somewhere I noticed someone using cement board as an insulating wall, I was thinking a cube made of that with a hinged side. Does anyone have other ideas for me? TTY

HELP! DRIVEWAY WARNING SYSTEM FOR CYCLISTS

My wife and I are moving to a new house that has a hidden driveway on a bend of a busy road that obscures our visibility as we exit. We are avid cyclists and ride around town on scooters, too. Does someone have a suggestion on a remote activated light system that could call drivers' attention to the driveway as we pull out? We have multiple lights on our bikes, but nevertheless, I'd like to enhance the safety of exiting. My only thought was to hook up some sort of lights to a darkroom timer and activate it for two minutes as we leave, but that would require burying a cable in pvc as far as I could tell, and the driveway is long. In short, it would be super inconvenient. What would be ideal is a remote activated flashing light set on one or both sides of the driveway, powered by battery that activated by the remote and turned off after a short period of time. Any suggestions on products or designs would be appreciated.

EDITED: "Odd things" people buy......recent "acquisition"

Recently I "acquired" a ClearVue device (pictures are mine) which claims to use the AC mains wiring of a house as an antenna to increase reception. What a bunch of malarkey. Oh, I am not saying it doesn't "amplify" the signal using power from the socket is gets plugged into, but that it is ONLY a signal filter. People I have seen that had one of these, bought it with the dreams of using the AC lines in their houses as an additional antenna, AND because it had, what appears to the untrained eye, a dish antenna on the front of it (it is just a piece of plastic adding no true value to the functionality of the device). Some people in marketing make me furious with how they attempt to dupe the public. *sigh* A forum was set up for people that had bought this device new, and some of the responses are scathing....I order the clearvue super booster indor tv antenna, in April 2002. They cashed my check of course but Never sent the product. I called the companyand the office is closed.go HERE for more responses.....The unit, I just noticed, has 2 black wires in it. The oddest thing I have every seen, really. One is hooked to a 5.7 meg resistor, the other end is soldered to the "cable" output. The second black wire is soldered to the AC / CAB switch (CAB side), which then runs to the 2 white wires coming in from the Mains plug - BUT it is not attached to them, but rather coils around them for about 2-3 inches. This wire terminates into the AIR. No connection whatsoever on that ends. And, coming soon to a thread near you, will be the second "antenna booster box" I got in this box lot - dissected.

Building integrated led rear mountain bike lights?

Hi folks ,as said above , would like to install a row of red high-power leds into the rear of my bike seat  post to give a hidden , high-tech look  :-). Elements of design to be considered ;  to run off  2-4 AA batteries , to use 5-7  5mm leds , to use        " off the shelf parts " , no hand built electronics , to have constant and flash modes , would consider adapting an existing product ( e.g. cateye light unit ) For the installation i intend to drill a row of 5.5mm holes , 25mm apart , with the led heads sealed in place just protruding the surface of the metal post. The led leads would be drawn up and out of the top of the seat post into the saddle area and is where the battery pack would be strapped in. Any electronics could be housed inside seat post or under saddle. A handle bar switch would be nice but not essential. I feel confident about the wiring and fitting of the components ( electrician by trade ) just need a pointer with the electronics. Cheers Pete.

5-10 USB charging hub

I have several USB devices in my house. I'm sicking tired of all of oversized chargers which take almost two spaces in my extension cord .Recently I was searching on the web 5-10 USB charging hub. There are pretty costly and even that many of them are low quality or if you try charge all devices at once it won't charge them. I found on instructable only one related topic only one topic. Unfortunately the author made his hub by disassemble bunch of USB chargers. I would like to made one from a scratch (including power supply). I would like to made my device so powerful that it could charge even 5-10 iPads. I found on the web instruction how to make USB charger recognizable by apple products (simply using rasistors). What power supply do I need to use?  Where can i find circuits schematics for such power supply for this specific power supply . How powerful transformation should be to run this?

Battery power and power consumption help!

I have a geocache project and need help with the power supply and power consumptin inside it. The basics of the project: It is a large wooden box. The box has a on/off switch. It also has various various coin slots. Flip the switch, turning it on, to supply power to the solenoid inside. Dropping a coin through the correct slot will trigger a momentary micro switch which activates the solenoid and springs out the drawer of treasures. Take your loot. Close the drawer. Turn off the switch and leave it for the next adventurer. And it works! Yay! Commoonents the question:  The solenoid is a 12v  door latch solenoid. https://www.adafruit.com/products/1512 The battery is a 12v 5ah sealed lead acid battery.  The coin micro switch is: https://www.adafruit.com/products/820 My question. This geocache that lives, protected, about 3 blocks from my house. I obviously won't be charging the 12v battery very often. Since this setup only has momentary power draw once in a while. Say once a week. Maaaaaaybe. Does anyone have any alternate power recommendations? I am okay with changing out the batteries once in a while. But I'm hoping for a once every few months. I originally used a new lead acid battery but it seems to have died. Possibly from letting the charge fall to low and then sulfation occured. I'm considering using a 11.1V Lipo Rc battery instead so I can recharge it at various levels of depletion. Thing is I need it to last a worth while amount of time without loosing power but also killling the battery from just sitting there.  Thoughs woukd be GREATLY appreciated.  -McG

Challenge: A key defroster for opening bike locks in winter.

Hello all.So I live in Montreal, winter is long here. Every morning opening our bike locks is problematic. We fixed it partially with lube, but this post is not about these solutions.I have been looking for a device that could heat the frozen core of the lock. You can see an image attached of a product not available anymore to get the idea. I guess it was not working very well...I have zero knowledge in electronics/electricity. I thought this question could be interesting/challenging for some of you. So ideally the gadget would be:Small enough to be carried on the key chain or in a commute bag.Able to be inserted in any type of locksBuilt with a safe way to prevent unwanted switch on (to avoid burning bags/pockets/houses...Lol)Able to produce enough heat to defrost the lock Rechargeable would be best (USB best best), capacity of 5mn maybe to operate twice a day...Reasonably quick to unfreeze the lock, so you don t freeze yourself (That s why I abandon using hot pouches around the lock, pouring hot water will fix it quickly but then it will freeze again)As I said, I don t have the skills to even begin to find a solution, but I saw a lot of smart stuff here and I am curious to see what you guys would answer to that. My guess is that it must be very difficult, if not I can t see why a similar product is not widely commercialized. I think a lot of people would buy it.Thanks for the reading, I hope I picked your interest. Have a good day.

The Bravery of Being Out of Range: A Technological Revolution

The 18th century gave us the beginning of the Industrial Revolution. Purpose-built factories for the new industries such as iron and textiles. New and improved methods of transportation, communication and production. It changed the way people lived / worked and it created / inspired a lot of what we still see and use today. This revolution had its negatives too. Jobs were lost to the industrial machines that did it better and faster, the poor and the working classes often had to endure grim living and working conditions. The black gold mined from underground, fuelled our thirst for advancement. Now in the 21st century, we are in the midst of the Technological Revolution. Ubers, drone deliveries, driverless cars and trucks, AI, Google, Facebook, Amazon Alexa, unmanned military vehicles, war by remote control and the bravery of being out of range. The drones, AI, robots and automation may not only take away our jobs, but potentially the need to leave the house or to have any real-world face to face interactions. They could re-define our lives, for better or for worse. Are you fearful? Wary? Or do you embrace the changes going on all around us?
