Super shallow well?

So I am building a small cabin in the woods near my house, It is on a very small ridge to the gully below. In the gully I dug a test hole for my well and had a hole at under two feet that fills up immediately when you scoop it out. Should I stay in this spot or will the water be bad?? I doubt if I can go very deep because the hole is now filled with water and there is about two feet of rock just under the surface I know because I dug a hole for something else nearby. Drilling of any sort is not an option as the rocks are to large. Should I just move nearby and try to go deep in that spot. I might get four feet in another spot. Thanks!!

How to Clean Silt from Dug Round Water Wells Used by 3-4 Billion People on Planet?

This is a clam shell bucket, from an old toy crane. I am taking this to a machine shop, welder, had having them make it 18 inches wide. It would be used only with rope, no block and tackle.  Problem: As best I can surmise, about 1-10 percent of hand dug, round water wells used by around 4 billion people on the planet are full of silt, dirty, and old plastic jugs used to pull the water up from well. As the silt rises in the well, the wells slowly become too dirty, or the locals need to pull the water out in buckets, then allow the silt water to settle. It is way to expensive for people who earn 10 USD per day to pay people with pumps to drain the wells. I want to create a 1-2 man powered clamshell bucket system to clean these wells.  What is the best way to make a method to clean a dug well? How much would the steel, rebar cost? Labor is 10 dollars per day in central American, South America, Africa etc. Thanks for help, I will take the finished bucket to Lome, Togo West Africa to test, and modify, iterate.

How to make one big battery out of several batteries (car/motorcyle/deep cycle), for a sound system

Hey everybody, I need your help on building a single battery out of several smaller batteries for a sound system in a particular environment that forbids the use of a fuel-powered generator and where electrical networks to plug into are absent. For now I'm just researching various portable batteries and think deep cycle ones are probably most adapted to the needs of a sound system running for 8-12 hours, but the only working example I've heard of so far is made up of several motorcycle batteries. I'm really starting from scratch and reviewing all my old electronics classes which I've never so far had to put into use, so bear with me :) I'm really keen on learning. As an indication, the sound system will be small with two high/mid built-in amplifier speakers and a woofer. Probably will need to run a few lights/lasers, that sort of thing as well, but that'll be a bonus. Thanks in advance

Electronic water level gauge for well

I have a 32m deep, 95cm diameter well, that is covered with two heavy concrete covers. The water depth is about 20m down from the surface. I cannot easily access the well to sound the depth or visually check the water level. I would like to build an electronic water level gauge that will tell me the amount of water in the well. I can then regulate watering accordingly. It was suggested to me that I use a washing machine pressure transducer but I have no idea of the circuit required. A refined solution would send data to my PC !!!! I have 240v AC supply to the well pump. Any ideas? Steve

Manual Water Pump

I am trying to build a manual water pump in my house. We are digging a well of about 320 feet (about 100m) and are hoping to pump water into an overhead tank that is about 13ft (4m) above the ground. Can anyone help me figure out how to build such a pump. Electricity is and expensive commodity in my area and that is why were looking to use a manual pump. Any input will be appreciated.

Depth of the thread cut by a tap?

If I was to drill a deeper hole, I buy a longer drill bit of the intended diameter.  I am sure the same thing apply to the taps as well.  However, in their specifications, I do not see anything about how deep a cut they would make.  So, my question is, what should I be looking if I need to make a deeper thread than than the tap I already have?  I mean is there a number which would say that this tap goes only one inch deep and so on? Thanks.

How can I get the dirt out of an old stone lined dug water well?

We have purchased land that has a 100 year old dug well on the property. Until about 20 years ago it was open, but the farmer of the property wanted to make the land a little safer and filled it in. When he filled it in, it had water at the bottom and was approx 30-45feet deep. Since the time when it was filled in, the dirt has sunk about 10feet. It is well made and is small round rock lined. I would love to find a way to get the dirt out of the well and at the same time preserve the nice stone work. It would be my hope to connect a solar pump to it and use the water for gardening purposes. Any thoughts on how to get the dirt out?

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!

where does electricity go?

I got a question. If we ground everything to the Earth for shorts and things like that, Where does that electricity go to? Does it just disappear deep down inside the earth? Does GE have an electrical well and is sucking all this electricity that people pour onto the ground? Please dont use big words like anode and cathode and coulombs (simple is better) :)

Thermal Cooling and Heating

It is very possible and it is in use today by using Thermal Cooling and Heating from the earth. Performed by using a 6" well at least 100' deep, with thermal tubing inserted into the well carrying the liquid to be cooled/heated. Process is done by a circulating pump in the interior unit - through the coil - sending back through the well system and returning. It starts out from the main unit circ pump.......through the coils.......out to the "down tube" into the 6" well pipe, a sharp 180* turn back up the system returning to the circ pump. Such a system is used by many facilities to Air Condition or heat rooms of about 15' x 15' or so. I have even seen a system that utilized creek water as the "cooler" of the tubing on a circ pump system. That one really was cool, about 52 degrees. Have you heard of these systems or seen something like it or close?

Can I use a bunch of AA Batteries setup in cells in place of a deep cycle battery for green power storage? Answered

Hello, I have been looking more and more into solar and wind power generation as well as ways to store the power. I am still in the planning stages and have not yet tested anything. What I usually see in almost every green power storage guide is to use deep cycle batteries mostly of the types designed for solar, golf carts, etc. That would work fine but they are always rather expensive atleast any I have found online (if you know a cheaper source I would love to hear about it). So my question is this could I just buy a bulk quantity of AA NiMH (the new ones without memory) or AA Lithium ion batteries and set them up in series to make cells of 8x AA per cell for 12v total then connect all cells in parallel for my battery bank? I am not sure if this would actually be more expensive as it is just an idea I had and have been unable to find someone that tried it (perhaps I am searching for the wrong thing). It seems to me this could be more effective as I could replace one battery in the cell when it goes out and be able to constantly repair the cells in that manner. Has anyone tried this and does it work? Would it require a special charge controller unlike the usual ones sold for solar? If anyone knows of any guides that show this please share them as I would love to do more research on this before I make a decision. I think I saw once on some show that the electric car they showed was setup in this way. Anyway thank you for your assistance it is greatly appreciated!

Back-up power

Hey there folks! Looking for some advise again. NH just went through the worst power outage in years (maybe history). 6 days without power has me thinking again. I have means of heat (wood stove) and means of cooking (propane) and lighting (candles and my LED projects), but the well pump is a problem. The need of water to flush the toilets came from the stream nearby, all well and good as it was, washing our bodies from buckets has to go. I have learned that my 220vac well pump actually draws it's power from 2 110 vac circuits. If I have this right (which is my first question, is this even possible) I only need a 110vac converter to run this off my batteries. Now, if I'm correct here (second question) a 4amp 220vac pump is 880 watts, then the draw from the 12vdc battery should be 74amps (give a few for losses maybe 80 amps). I only have 2 160AH deep cell batteries running currently. Am I looking at a reality of 2 hrs (half the draw) or 4 hrs use (full draw)? Or, is it even less.... Yup, that was a third question! I just bought a 2500 (5000 max) watt inverter intended for the shop and thought I would use this as my back-up for the winter. Am i even close here?

How would I go about building a portable battery power boom box with 2 tweeters and one large woofer.

Over the Christmas holiday I would like to utilize two tweeters that I obtained from computer speakers and a subwoofer that I obtained from a surround sound system to use in a portable battery powered boom box.  The goal is to makee the whole setup rechargeable (thought about solar panels also, but baby steps) with a usb slot (power only) to charge ipods/iphones and a single aux cable.  I have been experimenting with each of the speakers and I have an idea of what size of box I am going to have to produce the best sound, tips on this would be welcomed as well.  Strong deep bass is a major goal of the boom box as well.  Physical volume controls are not need.  The only button I assume would be for the power. Any tips or suggestions are welcomed.

Floating radio power usage?

I am building a floating radio to take on a float trip. I do not know much about power usage. I was going to use a car or deep well battery for power. I was wanting to run (4)-6X9 speakers, a amp, a 10" sub, and possibly some LED lights that would beat with the music that could be shut off during the day. Is this to much drain on the battery? The float lasts all day and I was concerned about draining the battery before the trip was over. I was told by the local Marine shop that once I start adding amps andor subs the power would drain much quicker. Any suggestions on stereo, speaker, sub, amp, size or the number of things I could run would be appreciated.

Why has nobody just dug down? Answered

I know we have really deep oil wells and geothermal things, but why have we not even attempted seeing how low we really can go.  In this day and age automation is easy and affordable, yet we haven't designed some simple machine to drill down to extreme temperatures and pressure to see what is really happening inside our earth. I propose a machine, similar to one of these http://en.wikipedia.org/wiki/Tunnel_boring_machine and we set it up to build a tunnel at a 45 degree angle and to place concrete pieces around just like it normally would, except on its own.  Water would be used to remove the material and if that became too difficult due to high pressure then.  A station would be built to boost pressure every so often.   Who doesn't think it would be awesome to walk around at the same depth as an oil well normally is, or deeper.  Because this drill is self contained it would have endless possibilities, at least until it melted or needed a cutting head repair.

Alternative Cooling design idea – Southeast moderate to high humidity

I need some serious feedback!  I have an 1896 Victorian, about 3800 sq.ft. but we did it right. Foamed the walls, floors, all new everything; a/c upstairs(2ton) and 5 ton downstairs.  It cools fine, but it's big and with only 3 of us, we only use about 2 rooms most of the time. Practically a new home. I've was studying underground piping for cooling but I have a new though. I can not use swamp coolers because it's to humid in Middle Ga. I have a well that the water is about 49-58 degrees. If I build a box with a cage fan and use small radiators (desinged for this purpose; not auto radiators), to pass the cold well water thru, wouldn't this work to cool the air for a room or two? I would design it to use a thermostat to open a valve when the water reached about 70 degrees and have it to RETURN the water back to the well (have have an opening to do so on the well). What I'm visioning is, the air would pass a hundred or so coils with circulated cold water all the time. I understand I need to also consider humidity dropping and cycle that out. Keep in mind, I'm not talking about passing air over a wet pad. I'm leaning toward passing air over cold coils that might be as deep as 3 feet. I really would like some detailed opinions. I'll email drawing if I have to.  Best regards.  Chris - Macon Ga.

why are my jalapeno chillis turning purple?

Hi, I am growing jalapeno's for the first time and something strange is happening, some of the jalapenos are turning deep purple. I was wondering, could this be due to sunburn? or mineral defficiency? they live in pots but the pot is way big enough, generally when the roots appear at the pot base i repot. Also ive added fertilizer a few times and added some seasol (seaweed extract) recently as well, so there ought to be enough nutrients in the soil. Could the purpling be from sunburn? some jalapenos are only purple on one side, and green on the other, or could it be sun exposure is causing some sides to rapidly ripen, such as what occures to some apple varieties . Does anyone know exactly what causes the purpling to occure, and will it at all have an effect on the outcome of the fruit?

I was planning on using the internal amplifier from the blown subwoofer, in this box, but I need to cut a hole to fit the amplifier in. It sounds really punchy, but for a 200 watt subwoofer (that's rms) it doesn't shake my floor at all because it's basically a sealed box, the sub comes out the front, should I cut a hole in the front or side for a port? What if I used the pipe out of the blow subwoofer box, or is it specifically tuned for the 8" that was in there before? Thanks for any help.

The front panels are already created and measure 2 x 2 1/2 feet each totalling a 8 foot height and 10 foot width. Please see image for example. I'm trying to figure out how to make a light weight frame for the panels to mount onto. The reason why the panel pieces are so small is due to shipping limitations so also looking for the frame to be portable as well. The longest size that I can go up to for any piece will be 4 feet in length. The frame will have to be free standing and may go up to 3 feet deep/back behind the wall front. There are no side, ceiling, or back wall to attach to so this will be a truly free standing unit.

Would mounting a TV inside a piano damage the TV?

We have an upright piano, and we don't have a good place to put our flatscreen. My thought is to put the flatscreen inside the piano. I have measured for clearance and it fits quite neatly. My only concern is if the vibrations from the piano will somehow damage the TV's electronics. On the one hand, the TV has speakers and generates a dynamic range of sound and volume and does just fine. The TV can get louder than we ever play the piano. On the other hand, the piano sounds are fuller and maybe vibrate more than the speakers in the TV do. More details: The vertical board behind and under the keyboard has a latch that is opened so that the board pivots down and forward.  The TV would go inside the space behind this board. It would make the TV close to the ground, but it would be more convenient than the current location. The space in the piano has a depth of about 6 inches. I would install a piece of 3/4 inch ply across the back to mount the TV to. It would be right in front and possibly touching  the sound board and the bass bridge. The TV is 4.5 inches deep at the deepest point. I am sure that the construction is feasible and well within my abilities. I am unsure of any danger to the TV from such a setup. Any insights, references or suggestions are well appreciated.  Thank you, Michael Moore

An Alarm Clock Idea - No Lights, No Sound

I'm a pretty deep sleeper, and I don't wake up very fast in the mornings, which is bad since I ride the school bus to school. I set my alarm clock, with a high volume, but it still doesn't wake me very good. I've thought of trying to make an alarm that flashes a strobe light, something like a deaf person might use, but didn't think it would work very good. So, my idea now is to think of a way to make an alarm clock that gives pulsating shocks when it goes off. I have absolutely (well, 99%) no idea how to connect it up, nor how to produce the shocks. I'm thinking a shock with high voltage, but low current, like static electricity. I figure that should wake me. Do y'all have any ideas, or better suggestions? Also, do you think that the shocks (if usable) would cause any dangerous effects on my health? Thanks!

Peltier Cooler/Heater - Pooling Brainpower

I recently acquired a thermoelectric mini fridge. As a fridge, it doesn't work so very well - it will get down to ~50 degrees with an ambient temperature of 70. So, I took it apart. You know the saying: "If it ain't broke - fix it until it is." So I now have a peltier effect cool/heater. I put my meat thermometer on the cold side with the fan off - and it gets down to freezing (probably a bit below). On the hot side, with a big sink and fan - it seems to be ~85 at it's warmest point (this sink is about half a square foot and an inch deep). Ideas on where to use? It's 110 service.... It literally almost killed me a few days ago when I touched a transistor sink that was part of the rectifier circuit while holding a plate that was grounded (I got knocked out for a few seconds) I've got a couple ideas, I just figured I'd pool brain power and see what happens :p

Inclusiveness - Whilst it may be cool to use the most current street slang or message-board abbreviations, there are those (myself included) who do not move in the internet circles where these terms originate. Excluding part of the membership by making the slang impenetrable also cuts you off from a deep well of information and advice. Time - slang dates, and changes rapidly. For instance, the word "gay" originally meant "carefree", then "happy", then "homosexual". Now, to the pupils at my school, it means "annoying" or "sad". Imagine what your latest slang could mean to future generations of readers. The web is a multi-lingual place. It would be conceited of us to assume that all readers speak English as their first, or even their second languages. There are a growing number of members and casual readers that rely on translation software to read this site. Translation software cannot deal with poor spelling or new abbreviations, and will render our words as gibberish.

How do you wire a small amount (8-12) LED's, to be run off a small battery and with a switch? In Laymens terms if pos?

Hi, I'm framing a piece of art with a deep frame and would like to put between 8 and 12 LED's in the frame. I will be running the wires and  hiding the battery and switch in a rebate around the outside of the frame. i will drill small holes in the frame every 2-3 inches through the frame for the LED's to be pushed into so they sit just below the surface on the inside of the frame. What i need to know is how to do it? From the basic knowledge i have i would have a 9v battery Positive wire into a switch,negative wire into 1st LED, then link all LED's with wire until the last negative wire into battery.  How wrong am I? I need to know how long the battery would last as well. Also needs to be wireless as it going to hanging on a wall. Thanks for any suggestions and help. And if anyone has a much better idea please let me know!!

A Transatlantic Tunnel, Hurrah!

Deep beneath the Atlantic Ocean, forgotten for the best part of a century, lies a tunnel linking London and New York.It was built on the whim of a Victorian inventor with the aim of linking two great cities and developing the kind of friendship that still exists today.But bad fortune befell the venture - and the tunnel lay idle ever after.Until today, that is.One end of the "tunnel" emerges next to Tower Bridge on the banks of the Thames in London - the other is next to Brooklyn Bridge on the banks of New York's East River.It looks like something HG Wells might have imagined.Each end has a giant telescope-like construction which appears to punch its way out of the earth.There are dials, and levers, and thermometer gauges on the side of the 20m long brass and wood construction.Peer into it and you can see people on the other side of the Atlantic.Wave at them, they wave back at you.Web-cam it ain't, but the Telectroscope is fascinating. I hope it's stays operational for quite some time.Telectroscope websiteDaily Mail articleBBC StoryBBC Video

If I wanted to make a homemade gel-cell or or AGM battery, what materials would I need?

I am thinking of building a homemade UPS (two actually) for use in my home. We have very bad power spikes and drops, and I have gone through 5 power strips in 4 months. My first thought was simply an off the shelf inverter and some lead acid (gel or AGM) batteries... but then I thought, why not go all out and make it all homemade? I know I can make an inverter myself, but have never attempted to cobble together a battery of any sort (unless you go back a couple decades and count the potato battery). I'm planning on making the UPS my first instructable, and would love to include (or have a second instructable on) the homemade battery as well. I'd want something that is deep cycle and which can support 1kw of continuous load pretty much 24/7 (assuming it is on the mains being recharged constantly).

Official: Crucifixion is Unhealthy

Health officials in the Philippines have issued a warning to people taking part in Easter crucifixion rituals.They have urged them to get tetanus vaccinations before they flagellate themselves and are nailed to crosses, and to practise good hygiene.On Good Friday dozens of very devout Catholics in the Philippines re-enact the crucifixion of Jesus Christ.It is something that has become a huge tourist attraction, although the Church frowns on the practice.The health department has strongly advised penitents to check the condition of the whips they plan to use to lash their backs, the Manila Times newspaper reports.They want people to have what they call "well-maintained" whips.In the hot and dusty atmosphere, officials warn, using unhygienic whips to make deep cuts in the body could lead to tetanus and other infections.And they advise that the nails used to fix people to crosses must be properly disinfected first. Often people soak the nails in alcohol throughout the year.Every Good Friday, in towns across the Philippines, people atone for sins or give thanks for an answered prayer by re-enacting the crucifixion of Jesus Christ. I'm sorry? But when did anybody think that being nailed to a lump of timber, hung out in the sun and flagellated was a safe pastime?BBC LinkPhilippine Department of Health

Comment Notifications

As you know, we're always updating the site to try and improve it for you. Sometimes we go a bit overboard... Recently we changed how you're notified when someone comments on an Instructable you wrote, or a forum you started, or replied to a comment you wrote, etc. People were getting a ton of emails, each with just one comment in it. So we created the ability to bundle these up into just one email, which you can get hourly or daily (or not at all). (Oh, and you can still get individual emails if you prefer - just update your user settings to suit you.) All well and good! But there was a small problem deep in the guts of the notification code, wherein it periodically skipped notifying some people of some comments, some of the time. Since a lot of people were getting notifications normally, it took a while to figure this out. I just fixed it... and there were a LOT of old comments that hadn't been sent yet, that just went out all at once! At least one user got notified of 93 comments. Anyway, I just wanted to let you know that that was a backlog, and not normal, and going forward you should only have the one hour's worth, or one day's worth, depending on how you've set up your account.

Custom Etched Halloween Tombstone

I created this custom etched Halloween tombstone using builder's foam, latex paint and spray paint. The method of creation is to use a water based paint to create a resist that will protect the foam from dissolving when painted with the spray paint. This technique works really well to create the weathered stone look that older limestone monuments take on after a couple hundred years. For this project I was trying to create a broken then repaired tombstone that was partially covered in moss. Project Process - First sketch the design layout using a marker. Then paint the areas that you want to remain un-etched. Next, spray the entire face tombstone with a heavy, even coat of spray paint. It will take a few minutes... but the face will be etched as much as 1/2" deep depending on how heavy a coat of spray paint. After the etching paint has dried, paint the entire tombstone with latex primer and then add any desired painted effects. For this project, I used a grey granite spray paint and then added sand that was painted a moss green color (adhering it with spray adhesive). Total active work time was approximately 2 1/2 hours. A full Instructable of this project to follow soon...

All I have is an idea (And a love of instructables)

Hello dear Instuctablists, You can't see me, but I am down on one knee. It's intended to show my deference to you. The reason? Well, we just finished rebuilding the ground floor of my house and there's now a big, deep-ish rectangular space above the toilet (about 70cm x 50cm and 15 cm deep). I was looking at it the other day, and had an idea for what I would like to put there that made me laugh out loud. The trouble is I have NO IDEA how to make it. Not only that, I can't think of any search terms that are leading me to 'how to' videos. In short all I have is an idea and no clue how to even begin making it. So, here's my idea. What I want to make is what appears to be a framed picture of two velvet curtains. BUT when you flush, the curtains draw back (like at the theatre) to reveal a small scene inside. Lights come on, some music plays, little toys/characters/puppets appear and then ten seconds later, the curtains close and that's that.  In other words and automated, electronic, toy theatre. So what I'm asking is either a) If you have any idea where I should start with this could you tell me where or b) If the end product sounds like something you'd like to see exist and you know how to make it, do you want to mentor me? (We could turn it into a YouTube video/series, do it over Skype or if you're in/near London, UK meet up IRL). Maybe I'm over-reaching in the help stakes, but every time I look at that blank piece of wall, I think: try. Any help gratefully received. Even if you can't help, thanks for reading this. RH (Also, I can't work out how to turn that picture round either. Sheesh. This whole thing is a TALL order)

Sound proofing shelf frontage help

I was wondering if any of you had any advice for the front of a whole wall shelving unit I am planning on building (and the shelves as well if you have any suggestions). You see, although there is a cavity wall between this room and the next, I am wary of a noise complaint as it is a different flat’s bedroom. I will be using it as a music production room and ideally want decent acoustics as well as adding an extra these extra layers to stop leakage. (I’ll draw some pictures and upload them to clarify what I’m saying)* Two things I’ve been thinking about using: 1.  A high-density curtain hanging in front of the whole unit. While this could possibly deal with the main issue of a noise complaint better than the next idea, I’m worried it will create a bad mixing environment with a really ‘dead’ wall behind my speakers. 2. Hanging, sliding acoustic panels using egg box foam under a sheet of fabric. This will look like a normal acoustic panel with the fabric pinned around a timber frame. I was thinking of forgoing using any sheet wood so I could hang a piece of high-density carpet/ fabric at the back and not have the panel too heavy. The wall measures about 3.2m W x 2.3m H so I was thinking of using three, maybe four hanging panels. It’s my understanding that a hanging panel would absorb more energy from the sound waves than one on wheels or in a sliding track. To hang the panels the main idea I had was to use metal tubing (uncertain as to what material to use, conduit?). With the three panels, I would use two main lengths of it one on the same height, parallel to the other, with the distance between needed to stop the panels on either track hitting each other. From above or below it would look a bit like this U=====U (sorry if this doesn’t translate to your device well… See pictures) with the ends of the U going into holes drilled into the wood, extending as far as the shelves will be deep if needed. With four I would just have two sets of the same but smaller. Sorry if this doesn’t make much sense, rushed off me feet at the moment. Many thanks Jay *Sorry the pictures ended up pretty awful, just moving in, need a proper table…

Silhouette Build Night at the Taipei Hackerspace

Hi, We just had our Silhouette Build Night in the Taipei Hackerspace yesterday. It was a blast, I was totally blown away by the many ideas people came with, even though we barely knew how to use the Silhouette paper cutter. We had participants of all ages, and many different backgrounds. The projects that came out of it, in no particular order: Dog silhouette cuts: apparently wiener dogs and corgis were the most popular, most just to keep, but there's an ongoing project to do a corgi-fan (hand-held fan in corgi shape) Custom cut name tags: because it's more fun than writing (Instructable) Cipher grille: because secrets are always fun, and it's easier than with scissors (Instructable); in the future might try circles instead of squares, that would look much cooler (hindsight...) Party props: most popular were lips and moustache, as usual... Flipbook: characters were cut and glued onto the flipbook, called "The missing piece" (Instructable) iPhone sicker: using some kind of 3D effect sticker, cut a it in the shape of the iPhone, perfect fit Pop-up word card: know the kind of greeting cards that you open up and there's a quasi-3D scene or text? That kind! Vitruvian man decoration: use transparencies with printed Vitruvian man, cut it out, then assemble into globes  for home decor (Instructable) Greeting card: creating a design with generous negative spaces, and use two layer of paper to assemble. Font selection is important (Techno Overload works quite well!) All in all it was good fun. I think we've ruined our mat by cutting too deep occasionally, running test cuts without pulling in the mat to the right position, sticking the printed transparency with the printed side down, and these little things. The biggest issues were the cut setting selection (lots of trial and error), and creating the design (now we have much better idea how to make JPEGs that work well in Silhouette Studio, but sometimes it was tricky using images grabbed from the net) Cheers! Greg
