build a propane powered freezer

I am interested in constructing a  propane powered freezer to store food.   The units currently for sale and way to expensive.  I recall  quite a while ago that some  supplier of  off grid equipment  sold the components to such a unit but I can no longer find them.  If  someone has built such a freezer I would be interested in knowing how they did it.

Say you had a giant wall designed for fastener storage....

I've been working on a project for the last week. When it's done I'll have a chunk of wall with: 90 1"x2"x4" drawers 64 3"x4"x7" bins 48 3"x6"x9" boxes My goal is to get all my various hardware organized and to fill in some gaps so that I always have a small handful of whatever size of nut, bolt, nail, lag screw, rivet, sheet metal screw, etc. that I need and don't have to go making a trip to the hardware store unless I'm doing something big and need dozens of something. So my two questions: If you had this setup, what sorts of less common hardware would you make room for? Where would you go to buy hardware to fill this thing up? I know if I go to the big box stores and buy those little plastic bags with four of this or five of that in them, I'm going to end up spending a lot more than I need to. I know places where I can buy hardware by the pound, so that will help keep costs down. But I'm also imagining that there are people here with on-line sources that might be cheaper still?

Overbed storage idea help.

Hey everyone, i'm moving into a new room in a shared house and i'm downsizing massively from my last flat so I have lots of stuff and no storage. i came up with an idea of having a bunkbed type frame to go over the single bed in the room but the top would be free for storage rather than a mattress. (I can't drill into any walls) does anyone have any suggestions or ideas how I could do this safely and on the cheap? I can get plenty of lumber and wood pallets for free but need help with the build ideas and instruction. thanks everyone CK

Library shelves & storage

I am trying to improve a run-down library where the shelves are almost on the point of falling apart and there are store rooms but no storage shelves or anything really. The library is run down and had hardly much spent on it in the last 20 years. The library is in eastern europe and since the fall of the the communist era and the rise of modern democracy the library has stood still. (Bit of a time warp!)  I am able to make most things in wood and have tools and power tools, bench saw and drill etc. There is also reasonable supplies of timber. (But not that you would find in western europe, think basic..) So the your challenge Instructables is! ideas and suggestions that I could use to replace the old shelves and sort out the storage. Think simple or at least simplistic and give it a go. Regards

Connecting Two Water Storage Tanks

There was a similar post to this one a couple of years back, the difference being that both my tanks are filled from separate branches of the same supply using a ball valve in each tank to stop them filling. I then have an outlet from both tanks connected together that then goes off to a pump. One tank is 5000 litres and the other is 3000 litres, currently the larger of the two is redundant and its outlet valve is off, but come the summer i will need to introduce the second tank. I am located in southern Spain and in the summer they turn off the water supply to save water hence the tanks. My question is as the tanks are of a different size, if i were to fit the smaller tanks outlet with a non return valve so that the larger tank can not fill the smaller one via the outlet pipe, would this work i.e. would the joint outlet pipe still feed the pump correctly or would it have more or less pressure. I appreciate that i could balance the two tanks, but i would much rather be able to use all the volume i can. Many thanks.

Demo (Contractor) Bags Are Sometimes Better than Garbage or Other Bags

Folks use garbage bags for storing and hauling .  Problem is, garbage bags rip easily and usually are good for one use. Demo bags are woven from polypropelene and are strong and  can be re-used.. Haul one load, dump it, bring the bag back,  Refill and repeat. Or use it for moving. No worries about ripping. They are not waterproof or completely dustproof. So one may wish to line it with a plastic bag. http://ecobrooklyn.com/demo-bags-trash-bag-alternative/ I think I may try to use this as a potato bag for growing potatoes a described in an earlier instructable

Ideas on repurposing over-the-door metal shoe rack

Hoping some creative minds can help me figure out a way to reuse a metal over-the-door shoe rack - not the"pockets' but the old school inverted U shape for about 18 pairs. Sorry -for some reason the upload pic isn't working - but it's 6 "U" on each of 6 rows with two side bars holding them together and two hooks at the top. I took it apart so I have 6 U rows and the two sides. I haven't figured out anything creative enough to justify mucking around with it, other than drilling holes in a vertical board to push the shelf in horizontally, and hanging lightweight things from it. There are easier and better solutions than using this in that case. Any ideas? Thanks/.

File Box for Index Cards

For some time I've been searching on Instructables for how to make a file box for index cards. No matter what word order or word types I used, what came up was making stuff out of index cards, or other odd stuff.  But nothing that got me what I was searching for. How to make a file box for index cards, needs to be basic & simple, not laser cutting (as don't have such). However, do have a box cutter, packing tape, handheld power tools: circular saw, saber saw, drill, just no tabletop tools, & no way to make, & no room to put any tabletop for such. I've looked at the Snap-N-Store collapsible index card file boxes, & have head/read by customer reviews that the snaps don't necessarily stay snapped.  I'm thinking if made w/cardboard or fiberboard (as the Snap-N-Store is) that something like corner brackets/braces (just not metal ones for wood)  can be used instead of snaps, & would hold together better. The Snap-N-Store boxes I'm wanting hold 1000 cards ea, & for ea size of index card 3X5, 4X6, & 5X8 I just need some help for a pattern & building instructions. Can anyone do an Instructable for such so I can follow & make them? Remember, I don't have, nor get access to, nor know how to use a laser cutter, or tabletop powertools. I just have handheld powertools of circular saw, saber saw, drill, & boxcutter, scissors & the usual handtools & hardware. Thanks

Australians! Urgent help needed!

Hi everyone! I don't really know what category this should be put under, if anyone think it's in the wrong place feel free to move it. I am a guy from Sweden who are backpacking around the world and I am currently in Perth, Western Australia. I'm going abroad to Laos tomorrow and I will stay in south east Asia for about a month and then come back. My problem right now is that I have some luggage (extra clothes and camping gear) that I need to store somewhere during that time. I called a self storage company a couple of days ago from Coral Bay and booked a locker at their facility, however they forgot to mention that I needed to be there before five p.m. when the office closes even though I explicitly asked if I could come by later since I would arrive with the Greyhound bus. Does anyone know any fairly cheap (the lockers in the airport cost 8$ a day, and that is a bit too much) place  that is open at this time, or even someone in the area who could could spare some space for about 1/2 cubic meter of luggage until I come back? If so, please contact me asap either here or on 0405682652.

Bay window seating question

Hello,         I'm hoping somebody can shed some light on a project I want to do. A new property I'm moving into has bay windows and I want to build a seat for the Mrs. to read and relax on, however any time I look for instructions it has you attach the seat to the wall. Would there be any detriment to simply building a seat in the shape of the wall and just pushing it against the wall without installing it permanently? I'm renting this place and don't fancy having to rip this out of the wall if they don't want to keep it. Thanks, Adam

Storage Space for Parts

I'm sure me and Skunkbait aren't the only ones who have kept car or motorcycle parts in odd places.I hear my dad kept a motocycle in his living room for years, because the place didn't have a secure garage. For a little while, if you wanted to sit while watching TV, you had to sit on the bike or the floor, because there was no other furniture. Plus, it's just priceless to be able to ride out your front door.I know some folks who keep spare electical bits like turn signals and partial wiring harnesses laying around the house. Hanging on doorknobs. Apparently, bachelors, those aren't just for hanging underwear anymore.There have been a few times that the chainsaw and lawnmower had to live in the house so a visiting motorcycle could live in our shed.Generally, whenever I get a new part or tool home, it has to spend some time just sitting around while I try to figure out what the best way is to use it. Or just figure out why it looked like a good idea to buy another timing light.I've been known to hang particularly sexy motorcycle parts on the wall. I spent a lot of time trying to get a 10-120 speedometer from a Volvo to work as a clock one time. That didn't work, but it did make a good paperweight.Where have you kept parts, and why?

Motor for ceiling mounted cargo box storage lift?

Hi there, A year or so ago, I purchased a Thule 571 Roof Mount Cargo Box Storage Lift and installed it on the ceiling in my garage.  The ceiling in the garage has a fairly high ceiling though and using the crank that came with the lift is a bit cumbersome to say the least.  I usually have to stand up on a tire of the car in order to reach the crank to turn it efficiently. So the idea popped into my head that wouldn't it be really cool to connect a reversible electric motor to the lift so I could just flip a switch to lift it and then toggle the switch down to lower it.   Here's a link to the specific product I'm using, which I think Thule has discontinued because I couldn't find it on their website tonight:  http://www.overheadgaragestoragesolutions.org/thule-571-roof-mount-cargo-box-garage-storage-solution/ My questions: 1) What size/spec motor should I get? 2) Where can I get the motor from? 3) I'm assuming that any electric motor can be reversible just by swapping polarity in the switch? 4) Do I need a belt to ensure that the motor doesn't spin the worm gear too fast or should it just be a direct connection? 5) Any other thoughts/ideas? There's an open 110v outlet in the ceiling of the garage where the garage door opener is installed, so I could run a power cord to that outlet and then I presume I'll need to run a wired switch down to the wall of the garage where I want to be able to control the lift. Thanks in advance for your time and consideration.  This would certainly make my life a bit easier to be able to quickly and easily raise and lower my ski box onto and off the roof of my car.   Regards, David

Connecting External Plastic Water Storage Tanks

I would like to ask a couple of questions about joining two external water storage tanks. The tanks have a capacity of 1,500 litres each and my plan is  to connect the two tanks with one inch pvc piping. The domestic water inlet is low pressure (and that's being kind!) but tank A is usually full. My question is will there be enough pressure in tank A to feed water through the one inch pvc piping and into tank B without using a pump? If you consider the water pressure to be high enough to transfer water from one tank to the next, how many tanks could be connected in this way (I am thinking of four tanks)? The outlet from the water pump feeds 9 washing machines in a small launderette. Sorry about the awful drawing. Thanks for any advice in advance.

Keyboard With On-Board Text Storage

Here's a thing I want, but have no idea how to build: THE INDEPENDENT KEYBOARD It doesn't care about computers! It save to itself! It's portable! There must be some way to build a keyboard that, once you turn it on, saves whatever inputs are typed to a plain text file on a thumb drive or SD card. Ideally, there'd be an on-off switch. When it's on, it's "recording" all inputs. Then you simply pull out the storage unit, plug that into a computer, and have your raw text. Any thoughts on how to pursue creating something like this?

What New Useful Products Have You Recently Become Acquainted With ?

Here is My list. I recently saw an ible about sugru. Had neverheard of it, before  but can see its usefulness. Kind of expensive and not generally available. Have seen polymer clays, but cant see how it would replace epoxy putty Available at craft shops. Have heard Rescue tape ( fusible silicon ) . I haven't had a use for it, but it seems to be a great repair tape. It was available at Craftwood  Lumber, so it is a mass market product. Expensive, but can see it's potential worth. I'll wait til. I need it before I buy it. The oscillating tools have come down in price. Not exactly new, but extremely useful especially for people whose shop is their desk or kitchen table. If I were to have one power tool, it probably would still be the cordless drill driver. But if I were allowed a second power tool, this would be it. Blades are expensive.  Demolition Bags are very useful and cheap and generally available. I recently saw a device for bending PVC pipe. I have avoided using PVC because of the joints. I prefer thin metal conduit because it can be bent with the pipe bender I was able to acquire. That being said, the Pipe Viper may  be worthwhile. I am considering a small greenhouse made of arched PVV pipe and clear sheeting.

Hydrogen for renewable energy storage- total system efficiency?

This is a question that has been bugging me for some time, especially since the questions about methanol synthesis revived my interest in energy storage. Say I have a wind turbine or solar panel or whatever, that produces 1000 Wh per day.  If I use that electricity to electrolyse water, store the generated hydrogen at roughly atmospheric pressure in an upside-down water butt or a big gas-tight bag in my shed (don't worry, I'm not going to actually do this) and then feed it into a generator converted to run on H2, what percentage of that initial energy input would I get back out?  20%?  5%? 1%? The follow-up questions to this are a) How does that compare against a battery bank? What about a similar DIY-style pumped water storage system? b) What one component of the system should be improved to raise the overall system efficiency? Electrolyser, storage, generator? c) Are there any other DIY-friendly methods for storing intermittently generated electricity that I'm not thinking of? And, I suppose, d) Does doing this and providing 5-10x your overall power requirements in wind turbines work out cheaper than spending thousands on batteries?

Heat storage device for car cabin heater

I want to increase the heat storage capacity of the existing car heater so that I can run the heater (just the fan and a liquid pump) while the engine is off and so I can have a warm car as soon as I start on a cold day. The current heat storage is the coolant circulating in the engine. I want to increase the capacity of that. Instead of simply attaching a liquid reservoir to the heater circuit (to increase the coolant volume), I was considering using a picnic cooler (insulated) box with a coper tube coiled in it. The box would be filled with oil and paraffin. Paraffin melts ≈ 40° C  and I can take advantage of the latent heat of fusion when the paraffin changes phase. The oil is a medium to suspend the paraffin. I need a recommendation of an electric 12 volt pump to circulate the fluid. I request any other thoughts or criticisms.

Inspiration: Lego lepdesk with storage

I was digging in my closet and found one of these. Basically it is a lightweight sort of flimsy plastic lap desk with two bins on either side and a track setup on top that fits Lego Plates. The plates slide into the middle to build, and slide shut over the bins for transportation. It can be carried like a suitcase. The user's legs sit in between the two bins and that hold the desk steady for building. This is definitely sized for a little kid, not a 6 foot four guy like myself. Lego made these back in the late 90's, no idea if they still do. You can find them online for exorbitant sums of money, $30-$60 US. A great design, and I am inspired to make some kind of work table. Seeing that these things are apparently collectible, I am going to sell this, then build a larger more durable adult version for all kinds of work with the money from selling this one. Sharing this here because I find this to be a nice and simple design that everyone can learn from. Any ideas? Lets hear them! I am envisioning some kind of clone of this made of medium-weight plywood or other material, with the leg space in between the bins used to hold another storage box that can be easily popped out. I really don't have the tools to do this project very cleanly, but hopefully soon I will make an initial model. For those lucky people out there with CNC machines, this is your chance to cut out something awesome. Take the idea and run with it.

Basement Closet Storage

Hi When I redid my basement a couple of years ago, I thought I was being a hero and built a huge storage closet. However, as my daughter as reminded me nearly everyday, I screwed up. The shelves are 24" deep and stuff seems to get swallowed up into the back never to be seen again. What I would like to do is this - any help? I would like to install 3 32" "box store" bookshelves (15" deep) against the back wall of the closet. Then, install another 2 of those bookshelves in front of the back ones on some sort of sliding rail(s) on the floor. What I am trying to accomplish is that when someone needs to get to one of the back bookshelves, they would slide one of the front ones over to reveal the back thereby allowing easy access to all "missing" stuff. Hope I made sense. Thanks

heating water using the sun

Hi I want to install a hot water system, as cheap and simple as possible.  The best idea I have found is to connect a new pipe to the main storage tank, and run it the 70 metres to the house, overground, so the sun heats it.  This will work, but it needs a one-way valve at the tank end to stop the hot water entering the storage tank and heating that.  The normal plumbing valves for this need a high working pressure, but our supply has only 2 metres of head at the point of connection.  Anyone know how I can get round this?

Idea to Store Solar, or Wind Energy in Tanks in Central, South American, Africa

 I go to Togo, West Africa, and they already use, or need the black water tanks. they can have the water pumped using solar, windmills, or rope pumps, then allow it to fall, and light their houses with LED lights, and charge their cell phones. So what do you think, anyone have experience using these cheap hydro generators? Do they work? Do they last? Is there enough water pressure?

Non SCSI, mega storage device?

So there I was, thinking that I had heard/read somewhere that it was possible to hook up many regular hard drives (IDE, EIDE) together to make up one logical partition that was dynamically expandable. I might be off my rocker, but I think I heard of it somewhere. An example is.. your company is upgrading it's computers, and intends to throw away old hard drives (i.e. 4GB, 20GB hard drives...) If you got your hands on them, you could hook them all together and make an expandable external storage. This would mean that if you have 3 20GB hard drives, you'd have a logical 60GB partition. Your buddy wants to throw away his old 10GB hard drive.. so you get that one and add it. Now you've got a 70GB hard drive. Has anybody ever heard of this idea before? No idea how to make it work, but I think in theory it would be neat.

Make supercapacitors from graphite in a DVD burner

The outline is that you can deposit graphite oxide (a cheap bulk material) onto a film of PET (the plastic used in Coke bottles), hit it with a commodity infra-red laser (such as the one in a $30 LightScribe DVD burner) and end up with a form of activated carbon material that can be used as the electrode in an electrolytic capacitor.  Add some aluminium foil, separator membrane and electrolyte and you've got cheap, robust energy storage.  The headline numbers are a few hundred milliFarads per cubic centimetre at a few volts, which works out to 1.36kWh per cubic metre of stacked capacitors.  It's still about 50 times less energy per volume than lead acid batteries, but you could store as much energy as your house will need overnight in the size of a garden shed or a set of bunk beds.  They charge/discharge in seconds and retain >95% capacity at 10,000 cycles so seem suitable for storage to even out intermittent energy generation from, for example, solar or wind power. I'm really thinking about cost here- unless I'm missing something fundamental it doesn't seem like producing these on a high volume roll-to-roll process would be excessively difficult, and the cycle life means the replacement time would be many years even in heavy usage.  Could you get sufficient kWh per dollar to make these a viable storage mechanism for home-scale renewables? There's a more informative article here.
