Raise Sunken Concrete?

Hello. I have a 5x5 concrete porch that has sunk 6-8 inches. The porch consists of a top surface with an 18 inch skirt, and a step. I believe it was a single pour.  The porch itself is in good condition, so I am seeking methods of raising it. I have looked into slabjacking, and pressure-fill lifting, but was actually looking for a pneumatic solution. any thoughts, comments, anecdotes, would be greatly appreciated. Thanks

Tiny Raised Letters?

I am looking for tiny raised characters, somewhere around size 10 font or smaller. It doesn't matter what they are made of, but I need the entire alphabet, preferably multiples of each character . The 'Made In China' text you find on almost anything plastic is the character size I'm in search of. Anyone have any ideas? Label maker characters are too large. I didn't see any rubber stamps with tiny characters at the local craft stores. I don't know if Ponoko can cut characters this small, but I don't think I could get something back from them in time.  Thanks!!!

Raising a geodesic dome

Just thought I'd share a time lapse video I made last year (but just got around to putting it online) Two of my kids are involved with a local circus and last year, said circus bought a geodesic dome to use as a venue for shows. There was great excitement when it was delivered and put together for the first time. It seemed appropriate to record the momentous occasion, but knowing how long it was going to take, a normal video was out of the question. So I set up the tripod and camera and took photos roughly every five minutes. The first photo was taken just after 9am and the last one was taken just after 5pm. It's quite an interesting structure and so strong, they can rig the aerial apparatus from just about any point!

Raise & Lower Spice Rack

I built a small spice rack that hangs on the underside of my kitchen cupboards (it is hidden behind the valence), and I want to have it raise and lower using a simple motor mechanism but I am a complete novice and I have no idea where to start.

Portable raised toilet seat

We are in search for ideas and/or off-the-shelf solutions for a mobility and toileting issue in response to the following request: "When I go out visiting or out on a shopping trip I often find the toilet seats too low, so I would like to see if a portable raised toilet seat could be designed. All I can find are the raised toilet seats where the existing toilet seat needs to be removed and then the raised toilet seat needs to be screwed on. [A possible solution would be to] create an inflatable one that can be attached to an existing toilet seat with something like velcro and maybe have a stiff ridge that can be secured under the existing toilet seat." Happy to hear your ideas! About Tetra Tetra is a non-profit organization that recruits skilled volunteers to create customized assistive devices for people with physical disabilities.

added value of raised beds?

My main hobby is gardening. I eat from my garden, 450 m^2, year round, and even have lots of extra space to play around, grow flowers or experiment. I see many new (US) instructables with raised beds, inspired by a popular book (Batholomeuw). It claims to have higher yields, and lower requirements of water, and work. In Europe, we are unfamiliar with this method (unless for elderly or handicapped people). It raises a few questions, but only to be answered by folks having experience in BOTH traditional methods AND the raised bed garden: In normal circumstances, do the claims of this method uphold? Adding the soil mix: 1/3 vermiculite (=clay), 1/3 peat and 1/3 compost. What kind of compost? Where does it come from? About the yearly renewing of the soil|:- again, where does the compost come from? For compost making: Is the household excess sufficient, or does extra material has to be added?? Why are these questions important? Gardening in the traditional way is nearly carbon neutral, unless all physical work is mechanized. But (the concept of) soil ecology is very precious; just covering it and putting this mix over it almost alarms me!

US vs UK flour

Curious observation from my mother's recent 3 months in the USA, she says she is unable to bake well when she was in the USA. Now, given mum is a pretty amazing baker on this side of the pond,  I am wondering why that might happen ? I wondered if  its "American flour", as opposed to "UK flour" - the recipe, would be the same kind of things, memorised over the years, like a simple scone, fairycakes, pastry.  Her main complaint was that items didn't brown, even at the same oven temperatures as she uses here, and after repeated experiments with the same recipes.

Raised Garden Beds out of Concrete Blocks?

I want to build raised garden beds with the walls being made out of concrete cinder blocks. Want the beds to be about 2 1/2' above ground and about 3' to 4' wide. I also want to make basically concrete counter tops to put on top (or benches). My question is .. how many inches can the top go beyond the concrete cinder block frame without having to add braces for the bench? Ex: if I use 6" wide cinder blocks .. and fill the holes with rebar and concrete .. what is the overhang I can have on the bench top?

My question is .. how far of overhang can I have for the "bench slab" on top of the "wall" without having to add braces etc? EX: if I use 6" wide cinder blocks (with rebar & concrete) .. and the wall is only between 2 1/2 to 3 feet tall .. and only being used to contain soil .. not to withstand major structural elements .. how far can the concrete bench top extend from the front of the wall?

Larger scale self-watering raised bed garden

Last year was the first time I did any gardening.  It was a result of an argument with my 3 year old where he steadfastly insisted that vegetables came from Kroger, not plants. As a result I started small with 6 pepper plants.  I used this instructable for a self-watering earth box.  It worked really well.  This year, I moved to 8 bucket fulls of vegetables. I've now maxed out what my porch can hold and want to move into my yard next year.  I have an idea for a larger scale self-watering raised bed system that I wanted to get some feedback on before I started building. I'm going to get a few of the small, hard plastic kiddie pools like these, approx 5' across.  I'm going to bury those and build on top of it a raised bed with a wooden floor.  In the floor I will cut holes and install several of the pond baskets referred to in the above instructable. My theory is this will work similar to how the earth box did but on a larger scale (approx 6x6 raised bed). Would love feedback and direction on this project.  I feel like it will work, but am a complete newbie and would love a bit of help on it.  Thanks!

Europe Turns Back to Coal, Raising Climate Fears

Europe, with its smart cars, good public transportation, and high density, is often a beacon of hope for environmentally-conscious Americans. However, since coal remains a relatively cheap source of energy (at least in the short-term...), many European countries are turning to it as oil and gas prices rise, and concerns about energy stability and independence grow stronger. Europe Turns Back to Coal, Raising Climate FearsOver the next five years, Italy will increase its reliance on coal to 33 percent from 14 percent. And Italy is not alone in its return to coal. Driven by rising demand, record high oil and natural gas prices, concerns over energy security and an aversion to nuclear energy, European countries are expected to put into operation about 50 coal-fired plants over the next five years, plants that will be in use for the next five decades. The fast-expanding developing economies of India and China, where coal remains a major fuel source for more than two billion people, have long been regarded as among the biggest challenges to reducing carbon emissions. But the return now to coal even in eco-conscious Europe is sowing real alarm among environmentalists who warn that it is setting the world on a disastrous trajectory that will make controlling global warming impossible.

Random raising and lowering led bars like a graphic equalizer??

Hello!

No different colored lights or anything required, I'm just planning to use white lights and colored gels.  http://i.imgur.com/QoPlA9b.gif I am primarily an artist, and have only done minimal work with small electronics, and I've never really created a circuit board, so I'm really not too familiar with the terminology and the ins and outs therein.

how can I raise an arm(s) with a switch easily?

REASON FOR QUESTION:  I would like to modify a Power Wheels with a pop up berf gun for my son.  So it would kind of be like a "raider" vehicle or weaponized dune buggy.   This is strictly in the theory stage. WHAT I WANT:  I would like to have a switch on the dash that raises the nerf gun out of the front storage compartment, or rotates it out of a cavity, or something like that, and then wire a momentary switch to either the dash, steering wheel, or horn that activates the "Battery operated Nerf".  WHAT I KNOW: Unfortunately I have no working knowledge of arduino or coding.  I would like to learn, but dont know where to start.  I do no electronics, and R/C.  Wiring the momentary switch to the "Nerf gun" should be no issue,  its how to "arm" it (for lack of a better term) that i dont know.       I was thinking that i could use a high torque servo, but I dont know how to wire it up to a switch, if thats even possible.  I then thought about a stepper motor, but again, i dont know how, and that route seems costly.     Fabricating brackets, arms, hinges, all easy.  CAN SOMEONE PLEASE HELP ME FIGURE OUT A WAY TO MAKE THIS POSSIBLE?  AND DUMB IT DOWN FOR ME AS WELL.  here are some concept pictures I was thinking of. and a few pictures of the tentative vehicle and Nerf choices.   the front of the vehicle has a storage compartment that should fit a smaller nerf easily.  I would just make a new split door for it, that would open up when the gun was armed.  that would be done easily with servos, if their was a way to.  at this point i might just make a roll cage to mount the VULCAN chain gun on and call it a day.  or hack a rc remote, but id rather not. ANY IDEAS?

Making coolest self-raising loft bed for kid - please help with hardware!

Hi everybody.  I am going to make a loft bed that will raise automatically when my kid gets out of it.  What I'd like to do (please see attached files) is suspend the bed via pulleys and cables attached to one weight.  The weight would be just a pound or two (trimmable, of course) more than the frame, mattress, bedding, etc. so it will raise itself until the weight hits a stop leaving the bed a few inches from the ceiling.  If necessary some friction could be used to keep the speed reasonable.  At night it should pull down quite easily, and I believe that with this layout, it should come down evenly regardless of where it is being pulled.   I had wanted this to "float", but since it is going to be in a corner anyways, I may run a couple tracks down the wall with hardware to guide the bed and keep it from swinging. The big question I have is how to fasten this to the ceiling.  It is drywall with joists above.  Offhand I'm guessing the bed will be say 110 pounds, so about 225 pounds hanging from the ceiling with the bed empty.  I'd like to have an extra, what, 500 pounds wiggle room?  Worst case scenario, two 150 pound people sitting on the end of the bed...  I mean I can explain that this is a one person only contraption, but I REALLY don't want it coming down regardless of what gets thrown at this thing. Any ideas, criticisms, feedback, will be so greatly appreciated.  I think this could be really awesome, and I know it will make my son flip out!  He's got a very small room, and this will free up so much space. Thanks again.  John

I fell dumb for asking , but is this a good idea to raise ducks from the wild as pets? (I've never heard of a story in the news where a duck has harmed a person before so...) Has anyone raised a duck before? What are your thoughts on this? haha, if we really do this, I could probably post an instructable on how to raise ducks if this goes well.
