The Ammonia problem...

I am still trying to build a half decent absorption fridge/freezer for the hot summer days down here. Usually anhydrous ammonia and water is used for these old style systems. Problem is that destilling it at home is not the nicest thing, especially in the currently hot weather. So I called up a few refrigeration guys to inquire on the price of some Ammonia if they fill the system for me instead. No matter how I try these guys will only fill certified systems but nothing build in your backyard that is missing the required certifications. Not even for a proof of concept to see if it is working and the gas removed when done with that. Was also informed that making or just having highly concetrated or even anhydrous ammonia would require that I obtain a permit first :( Big question: What are the alternives for R707 or Ammonia in an old style "Icy Ball" system? Small question: Has anyone done it and is willing to share some tips here?

Low voltage health problems

Hello, I saw a great project on youtube, a water button, and gave it a try. it works, all it does is when one touches water, a led turns on, just a proof of concept. But what I was worried about, is if there are any negative health impacts of 3.3 v going though you and into the ground? The power is not noticeable, but still, I worry. ps. I did Google this, but couldn't find anything.

White Glue problem

Does anyone know how to remove white glue from a fixed chair? I'm fixing chairs for a pub around, but lately interchanged the wood pieces of the upper left and right. I noticed this 6hrs later, when it was too late to disassemble/tear things out. I know, basically it's possible to do so with water or heat, but in this case the glue is in the chair itself, so i guess, i can't heat it up - i thought about putting the chair into to a tub to soak it with water, but then i'd have the problem that even the chair's wood itself is soaked. Any suggestions?

PVC plumbing problem?

I'm installing a new heater for a spa and am having trouble hooking up the plumbing. I am using 2" PVC and have built the whole manifold from the filter to the heater and to the return to the spa, but I can't figure out how to hook it up to the existing pipe that returns the hot water to the spa. It sticks up about 5" out of the cement pad where all the equipment is located, but it's not a standard size/shape. It's shaped like a car radiator's hose nipple with a bulge between two narrower bits so that you could put a hose over it and clamp it behind the bulge but i'm trying not to do it that way since the hoses that are used with PVC aren't meant for pressure or heat. That is how it was originally hooked up but when I took it apart the hose was all deteriorated on the inside. None of the exposed part is a standard size where I could just cut it and bond a coupling on. I was thinking about trying to use a radiator hose but don't know what the spa chemicals would do to it.?

Interference of codes problem

I want to ask for some help from you regarding of my final year project. I'm doing a simple SMART HOME project by using Arduino wemos. While compiling the function of the smart home, i've encountered some problem to compile it. Actually this is my first time using arduino and i don't really understand about the arduino ide syntax. Actually, there is no error in my coding. Basically, there are 5 functions that I want to put in that smart home. First, to control the lights,curtains and fans using ON/OFF Button, and security system only by using TSOP and IR, and lastly controlling the roof for the clothesline. So, I've problem with controlling the roof for the clothesline. The roof for the clothesline works when the rain sensor detects water/rain and it actually functioning when I do it separately. But, when I compile the code with the other functions, the roof is actually functioned, but it works only if I switch ON/OFF the lights/fans/curtains. So, here I attached the source code of my project with four functions, which are for the lights, fans, curtains and roof.

Power supply problems for my project

Hi everyone. I'm stuck with power supply problems in my project. My project is a drink dispenser (cocktail machine) with water level indicators. I was thinking of putting 4 water pumps connected to relay modules, controlled by Arduino or microcontroller (something like attiny). The microcontroller would receive a command with 2 push buttons (tasters) and depending on the button pressed, it would combine 2 liquids from 2 tanks into one glass. Now, the code isn't a problem. I need to add a liquid level indicator to the circuit (4 indicator circuits for 4 liquid tanks). Now, the pump I was thinking of buying is rated 5V and the current draw is about 150-250 mA. Attiny2313 operates on 2.7V-5.5V. I found the water level indicator circuit also rated 5V ("https://www.electronicshub.org/water-level-alarm-using-555-timer/" but I was thinking about the one without 555 timer). Now, my question is, what is the best way to power all these components. I was thinking about getting a 220V to 5V 2A PSU adapter ("https://www.ebay.com/itm/AC-110V-220V-TO-DC-5V-12V-24V-Switch-Power-Supply-Driver-Adapter-LED-Strip-Light/152134115704?hash=item236be66178:m:mnohYz4NZlT_Dq5l5lWNUMg:rk:1:pf:0"). Will that be enough and will it destroy any of my components. Thanks in advance!

My camera works only when hot, why?

Introduction; I live at Thailand, and Thais have holiday named Songkran where other people splash water on each other, so i took my camera out to shot some photos of the festival, and someone accidentally splashed water over me and my camera! So i took the battery out immediately and when arrived home disassembled my cam, it was full of water! So i dried some of the water with toilet paper and used a hairdryer on first lvl heat to dry it more out, after that placed the camera in the container with silica gel for 10 days! After 10-12 days i assembled camera and it worked, i was very happy.  Problem: Now after like 6 months my camera stopped working, and i found out that when i leave it near heat source (my laptop hot spot on top of the processor, sunny place, or even on very hot day) it starts to work again. First the display acting weird and messy, than it becomes green, and i leave it for 3-4 min like that. so it heats a little bit more.and after that camera works normally! but if i leave it to cool down it stops again! My Guess: I think i made a big mistake using hairdryer at all, and while in that process some of the connections could widened and made cold contact! I assume problem is somewhere on the main or power board since when i put the battery inside camera power control light doesn't respond at all. Question: Anyone can help me with some tip where the problem could be, or the possible solution? The Nikon shop does not want to repair water damaged camera and even if so, it is very expensive that i could buy new camera! Feel free to aks anyadditional questions! Thank you

Problem with too much window condensation

I have double pane, insulating glass house windows that collect condensation during the winter heating months. The condensation is not between the panes, it is inside the home. The water builds up and runs down onto the wood frame causing rot. It occurs only on the bottom inch or two of the window. The home is in Northern Wisconsin where it is commonly 20 deg F outside and 70 deg F inside. The interior humidity is controlled and not excessive. Aside from setting the interior humidity to desert-like conditions, how can I remove the moisture and prevent further damage to the frame? Desiccant bags? Solar powered fans? Any ideas would be greatly appreciated.

Rust in old water pipes? Answered

Problem: The house I moved in to still has galvanised steel pipes for all water connections. The rust and deposit build up is so bad that with a pressure nozzle on the garden hose I reach aroun 20m from the tap near the mater meter but only around 5m in the backyard. To make things worse these restrictions affect the hot water. If I open the hot water tap and then open a col water tap the hot slows and then the flow fully stopps. The landlord already stated he has no intentions of replacing the pipes at this stage as it is quite costly. The possible solution: I was thinking of flushing the system with oxalic or phosphoric acid to break down rust and deposits. The questions: Has anyone tried this and has some feedback on how good or bad it worked? Do I have to fill the entire system with the acid or is it enough to get a few liters in and hope it will spread/dilute through the system within 24 hours? Is it advisable to use a bucket and aquarium pump (probably something stronger) to circulate the acid through the pipes?

What a waste of F'ing water....

I know it is important to keep certain systems running reliably... But this seems ridiculous. I came home and heard a lot of water rushing into the drain. Not far down the street, I see a yellow box dumping hundreds of gallons of water. So I ran inside, grabbed a flashlight... ran outside... flashlight is missing a battery... ran inside, got battery then ran outside. I got next to the box and called the phone number on the side. Water management picked up. I explained that it was a yellow box next to a fire hydrant on a concrete pad. The tech immediatly knew that it was just "flushing the system" and said it would be on for awhile. He thanked me for calling and I hung up. 6 months ago, that box wasn't there. I've lived in this city for over 15 years and never saw this. To me, it seems like a lazy and poor solution to some problem I can't seem to find searching google. My guess would be sediment from lack of use (but iono). Anyway... I thought I'd share my frustration.... Oh, it was on for 2 hours! after I got home..... just wow.

What thickness of plexiglass is best to use for a water block? Answered

Ok, so about three months ago I bought a 168W peltier unit off of ebay. I wanted to fool around with the cold side, the only problem was that I did not have a large enough heatsink to disapate the heat. And thus the peltier would overheat after 20 seconds.

I need some help finding the best way to make a lightweight heater. Lots more info in details! Answered

So for one of my classes we work with a random company to solve some sort of problem that they have.  It’s an engineering class so the problems are all solved with physical things that we have to design; I just thought I should be clear that we weren’t solving financial problems or anything like that.  Anyways, my project has to do with keeping water in a tray (48mm x 60mm) at a certain temperature for a period of a couple of hours.  The water needs to be held constant at any temperature between 20 and 40 degrees Celsius.  My first thought was to use NiChrome wire to heat it but I don’t know how well that would work at lower temperatures so then I thought to use etched pcb as a heater but I’m not sure if I could get enough resistance from so little space.  The other restriction I’m facing is that you must be able to see clear through the center of the tray and whatever I’m using to heat it (lets just say a hole 1cm x 2cm must be left in the center) which reduces the resistance I could get from pcb even further given there is less area to run traces.  The heating apparatus must be as light as possible and I feel like electronic heating is my best bet since it is the easiest to control.  If you have any suggestions or think that my ideas are dumb or anything just let me know.  I’m happy to get any input here.  THANKS!

How to let something spin in water without moving ? Answered

On top of the can there is a propeller which is stuck to the can. The hot air rises and lets the fan (and therefore the whole can) spin. The power is very little and the can tends to move to a side of the bowl and that friction stops it. Is there a balance problem ? Is the not perfect propeller working like a sail and therefore pushing it to the side ? What could I do to let the can stay perfectly in the middle while spinning ? Thanks in advance.

And is there a way to manually adjust the ratio of air-to-combustible? The reason I ask is because I was hypothesizing whether or not it would be feasible to replace gasoline with a more efficient combustible, and this combustible would greatly depend on what is actually put into a modern petroleum-based car engine's pistons.

Distribution of Solar Heated Water and Any Other Heated or Cooled Water

I started this project about a week ago after seeing the Instructable – https://www.instructables.com/id/How-to-build-a-strikeheliostatstrike-paraboliI made mine out of cardboard and then coated the cardboard – front and back – with fiberglass resin for stiffness. I covered the inside with tinfoil to test it out and find the focal point. It worked great with the focal point at the center of the dish even with the lip of the curve. I then removed the tinfoil and replaced the tinfoil with mirrored Plexiglas. Now it works awesome. I have a 30� parabolic mirror that can ignite wood almost instantaneously at the focal point of the light.Next I constructed the heating coil to run water through. This is made from a large 1 Kg coffee can, 16’ of ¼� copper tubing with end fittings, and the glass lid of a small sauce pan (handle removed). The outside of the coffee can is painted flat black as is the copper pipe. The copper pipe is coiled to a coil 4� in diameter and 6� in length and inserted inside the can with the ends extending from the side of the can through two drilled holes. The inside of the can is not painted, but left shiny. The glass lid is then taped over the hole with aluminum metal tape covering a minimum amount of the glass – about 1/4� around the edge.The coffee can is then suspended over the mouth of the parabolic mirror by a three point 6� chimney pipe stand-off. The can’s mouth is centered at the focal point of the mirror so all of the light being reflected by the mirror must enter the coffee can. Hoses are hooked up to the copper pipe fittings and these lines go to the feed/storage tank.The problem with the conventional set up from here is that the speed the water moves at (slow) to be heated to a great degree causes such great loses through convection, this system is not really feasible. I propose a new idea – or a new twist on an old idea.I noticed that the solar heat generating station use a black water pipe inside a glass vacuum tube to generate heat from the sun for heating water. I said to myself that this is a great idea and plan on building the next heating coil in a vacuum chamber. But, I also came up with the idea that the if the water is heated in this manner, why can’t it be transferred to the storage tank in a similar manner.If the feed lines were suspended inside a larger outer line and the outer line sealed tight and vacuumed the heat transfer due to convection would be almost nil. I estimated that with a total convective area at 100% the use of plastic stand-offs (8 @1/8� thick over 12’) the convective area would be reduced to 0.6%. Unbelievable! Even if this rose to 5% it is far beyond anything in use today by the home owner. Stretches of pipe going 100s of meters would no longer be un-heard of. You could place the dish in a close by field away from the trees and house and pump the heat back without losing it to the ground.This would also work for outdoor wood furnaces if use today. An outer pipe could be added over the existing pipe work, sealed, and vacuumed – almost all heat lose would be gone. And much larger stretches of pipe could be used here also. They would no longer need one furnace for the barn and another for the house. With this system, the pipes could even be run above ground, if desired, in some cases.This could also be used to replace insulation on cooling lines also.The key to the system is minimal contact between the inside and outside lines, and the vacuum between the two lines. Remember, there is no transfer of heat through convention within a vacuum, because there is no air for the heat to transfer through.As with all the new ideas this could get costly depending on the scale of piping you are dealing with – but the savings from reduced heat lose will far out way these cost in the near future.I may get an Instructable out for the Energy efficiency contest, but will be hard pressed.

Would this matter if it was only being used to flush the toilet? If it is a problem, is there a simple/compact/cheap way of filtering the water first? 2. You'd need to make sure that there was always enough water in the tank to flush the toilet, so there would need to a minimum amount in there that if there wasn't enough greywater from the shower available, that it would get topped up from the mains water. Would you use a float valve for this or is there a better way? 3. I'm not exactly sure where I would be able to position the tank. Either way I would probably have to use a pump of some sort, either to get the greywater into the tank or to get the water from the tank to the toilet. Should I just use a submersible pump or something else? Any other ideas or small projects that people have done would be great to hear about. Thanks James

Large Scale Water Level Indicator

Hey everyone, I hope im posting this in the right spot.  I run a large farming operation and get my water from a well that pumps into a large storage tank about 10 feet deep and 6ft diameter.   Because the well is very old I'm not able to add things like a float that will turn it on or off for me so I'm constantly having to check the well though out the day and if the cows are more thirsty one day they can drink the storage tank dry and that causes me problems with my pump, or if i leave it to long it will overflow and it makes a terrible mess. So im wondering if there is a way that I can wire up a water level indicator in the well-house and have a light board in my house that shows me the level of the well.  So for a 10 ft deep well id have an led light for every 1ft or so and when the water level gets to the top foot a buzzer would go off and when it hits the bottom foot or 2 ft then a buzzer would go off.  Ideally a wireless transmitting to the house would be best but I have no idea how that could work.  And wired would be hard with the well house being a few hundred feet away from my house.  I've done a lot of googling and haven't found anything that would suite a large scale water tank like this.  I purely want to be able to see in my house where the water level is and have it warn me when its too high or too low.  I apologize since i don't have a lot of experience in electronics.  Any help is greatly appreciated as i have no idea where to start or if its even possible.  Thanks guys!

Terrace Cooling System - Ideas

Hi, my name is Michael and I'm from Austria. Nowadays we have about 38°C (100°F). We have a Terrace which has a area of 33m² (355.21ft²). This terrace has a roof, which consists of polycarbonate plates. We have the problem that it is very hot on our terrace although we use awnings. Now I've discovered some ideas how i could cool down our terrace. The first one could be a water cycle, with a container and a pump. Then the pump could pump up the water. The water flows down the roof and flows back into the container. I don't know if this is a efficient way to cool down our terrace? The 2nd possibility I discovered is water mist. I found this video to show the principle: http://youtu.be/bYTcMCm2zWg I don't know if it is possible to sit underneath the water mist without getting wet?? I just want some Ideas and oppinions. Maybe some of you have realized their own cooling system? I know how to program an Arduino and other microcontrollers and I am able to develop electronic circuits. So I think i have the basic knowledge for building such a system, but I can't decide which principle i should use? I am sorry for my bad english skills, but i hope that you can understand me.  Thanks in advance Mike

Solar Hot Water Preheater Idea?

Hi everyone, I'm new, from the UK, I will shortly be moving into a static caravan/mobile home on family land for a few years to save up, so with money saving being the aim, I'd like to run this little project by you all.  I'm thinking about making a solar collector and placing it on the roof of the home, as large as I can afford (caravan is 12 wide) and feeding that into a heat exchanger inside an old 47kg LPG gas cylinder (I have access to several old cylinders and believe it can hold around 110 litres, so could even use 2?) and having the mains inlet at the bottom and outlet to the boiler at the top.  For the heat exchanger, I'm thinking cut both ends off and drop a coil through from top to bottom and weld back up but i'm open to suggestions. I want to a heat exchanger instead of having the mains water go round the solar collector, as it can get cold in the UK at night, even in the summer and I dont want it freezing in the winter (i'll have enough worry of water pipes freezing anyway), so will use some form of copper friendly anti-freeze. I'll need a pump for this, as the collector will be on the roof, above the cylinder, so thinking to run it on a light sensor, but how complicated would a thermal switch be, so when the temp in the collector ir warmer then the cylinder be to make? If anyone knows of a  place for the circuits (or of the shelf product), I can see if it's something i'm competent enough to take on.  One last thing, Would having the cylinder painter black and left in sunlight be a good idea. Would it get hot enough to cause problems with the water mains pressure?  Look forward to your feedback and advise.  Tuns
