For some people buying a decent grinding or honing stone is a lifetime investment.Prices of over $500 for a single stone of a very fine grid are not uncommon.But what about the average Joe who just needs to sharpen a knife or tool every now and then?If slicing and dicing is not your living than investing in a set of diamond plates might be better than getting a set of stones.But there are limitations, firstly their size and then how long they last.The later is really important if not used correctly as even diamond toold can be ruined quickly.In some case these small sharpening tools are hard to handle.The bigger plates can still be a pain if they don't come with a proper mount.Well, and if you forget to clean them after use and put them in a dry place it will be quite hard to remove the rust.A nice alternative I found is sandpaper, specifically sandpaper on a glass plate.Good wet and dry sandpaper is available from almost gravel to a 10.000 grid, above that you might have to make a special order.In general the finer the grid the more you pay due to the ingredients.I use a glass plate from and old scanner as they are both heat proof and really strong, window glass is not recommended here.The glass is covered with strips of kapton tape for the ease of later cleaning.The tape is then evenly covered with a contact glue, preferably the spry king to get an even cover.Same for the sheet of sandpaper.I try to get the glue over the glass edge a bit and to have at least two sides of the sandpaper going over an edge.Just to have an area to work close to the edge without risking to lift the paper off.Once a sheet is too worn I place the plat in the oven for a few minutes so the glue softens and peel the sheet off.If too much glue remians on the tape I replace it before I put a new sheet on.Of course you need a bunch of plates although it works fine with two different sheets halfing a plate.The thing works best under slow running water, so use your tinker skills to come with a suitable frame and water supply ;)But even with just a spray bottle it is a cheap way to replace a costly stone, especially if you do require a bigger surface area.

Hi, I want to make a whole bunch of lowtec-throwies, just a simple version to decorate and take pictures here, not the ultra-bright highly magnetic kind.The problem right now is that 200-300 throwies with cheap LEDs would cost more then $100 if I get the parts at our local electronic store (and that without magnets)."besthongkong" has 1000 LEDs for $10+$10S/H (=2 cents each) but does anyone know another cheap source with a larger variety and colors of low cost LEDs, maybee even low current ones? Maybee even in Europe?Second thing: Batteries. Lithium cells are rather pricey at that quantity, and cheap button cells seem to do the job.I had a couple of 1,6v LEDs on two button cells with diods I had lying arround (voltage drop). It was not very bright but they still glowed a week later.I had a cheap 12 pack assorted buttoncell blister, and I foundhttp://www.dealextreme.com/details.dx/sku.61But they seem to have even worse quality ;-) Idd probably have to use three or more and still throw some out.I remember an experiment using wire and coins, lemon juice or vinigar, which made a LED glow dimly. Any Idea how long before this DIY-Batery runs out?Third thing: Magnets!DX has 20 for less then $2. but I guess at that weight I could just magnatize some scrap metal and cut it into pieces. Thats about a third of the costs even with all the shipping :-)Anyone here that knows any other good site for LEDs, magnets and such that ship to europe?

Hey everyone, as you may or may not know, I've made the only homemade and documented cotton candy machine on the entire webbernets. Now, I'm back, WITH A VENGEANCE..... kind of... I'm looking for a place where I can get a cheap 6" round bar of 4.5-5" diameter aluminum, for Cotton Candy Machine: Mark III (The prototype was Mark I) I'm also looking for one of those cruddy 30 second cotton candy makers that you used to see on the T.V. ads all the time. I really need a better solution for the heating element problem. ANY help/aid is greatly appreciated!! Yours Truly, -The Muffinator

This is a quick CALL FOR HELP regarding the restoration of an old steam trunk. The idea is to convert it into a stylish coffee table and storage space and I could really use your suggestions on how to strengthen it's construction and embellish it's exterior. With your help I'll go forward with the plans and publish my progress here. The timeline is also important since the trunk occupies considerable space in our little apartment, so ideally I would like to finish all the woodwork within the next couple of weeks (until beginning of May 2012). The exterior and small touches could wait. HOW I FOUND THE TRUNK I found the trunk next to our dumpster 2 days ago and I just couldn't believe it - Who would throw away such a beautiful thing? - Was I such a good boy that Garbage Santa gave me this gift for Passover/Easter? I hauled it to our flat - my wife asking me what did the cat drag in this time.. (she just loves it that pack our home/car with stuff I find) she couldn't believe her eyes when she saw it. Since we live in a flat with almost no storage space it's very difficult to put together all the needed materials for this project, plus, I insist on doing it with recycled wood (what I find lying around) so to minimize costs. Requirements: @ The trunk should be sturdy (kids might climb on it at some point, ~20kg on the lid). @ It will probably hold a big pile of magazines (10 - 40 kg on the bottom), pillows/blankets. @ I want to add 4 or 6 casters to the bottom so it'll be more mobile. @ I think there should be additional internal support where the leather handles are so when they're pulled I won't be standing with one side of the trunk in my hand. Materials: - Wood - I currently have a solid pine wood dresser in my car, ready to be disassembled for it's beams (?) - OSB - there is some around where I work, 10mm thick. I'll try to find any more materials you'll suggest. Tools: - Drill (and screws) - Glue gun - Staple gun - Carpenter's glue - Hammer - Oxalic acid - Will need to finally buy a Gigsaw.... Trunk internal measurements: Length - 980mm Height - Box - 485mm, Lid - 105mm Depth - 559mm The trunk's side thickness is about 7-8mm made of ply wood covered with black leather. I has seen better days, but it's in relatively good condition. We were thinking of gluing the black surfaces with some sort of bright colored wallpaper (leaving the black leather lining with pins visible) so it would give it some sort of lightness - less bulky. I was also thinking of maybe gluing some sort of fabric with a cool vintage design, but it seems like a lot of work making it look good, stretched with no wrinkles, excess glue... plus it'll probably gather a lot more dust than a wallpaper (I'm allergic). There are two issues that concern me: 1. A fear that this current design isn't strong enough for a clumsy family. 2. I want to attach the corner supports and lid OSB without needing to drill the exterior (too much). I thought of using a lot of glue, but I'm not sure it's the best way to go. What do you think? I'm also attaching this design in Google SketchUp.

I am currently working on a new idea in which the nosecone of a model rocket is made from wood putty. Here are the steps: 1. Make a a frame made from a thin piece of balsa. 2. Fill in the four sections with a generous a mount of wood putty or wood filler. 3. Sand using a rough sandpaper, then something finer 4. Attach a dowel to the bottom and add a screw eye Do you think it will work?

I want to make a relatively small hammock stand no more than 6 to 7 feet in length for my dorm room. It should also be able to collapse easy for storage purposes. done any one have any plans that would allow me to do that? i was thinking about building it out of 1-11/4 PVC but that might be too flexible and break. ( i weigh around 170 lbs). thx guys

I've got a cheap voice changer that is hard-wired to a computer-style microphone. I cut off the mic and added a 1/8" miniplug adapter, so as to increase flexibility. I need to connect the powered headphone output of an mp3 player to this voice-changer, what is the easiest way to do so? I tried an attenuator I had lying around, but got no results (are attenuators one way?) is there a good (cheap) solution to this problem?

Greetings! I need help finding a material for a project. I am looking for the cheapest Thermo-formable plastic that I can find. I need to be able to form it with a heat gun and keep its rigidity after forming. I also need to be able to paint it. I require a large amount so I am looking for the cheapest. Any suggestions would be greatly appreciated. Thanks

I like making these snow globe thingies, or just oil and glitter in a bottle. They fall slower when you use oil rather than just plain water, and I saw someone recommend baby oil. However, its a bit expensive just for this use, especially the colorless one. So I'm looking for any type of oil I can use for this project, that is cheaper than baby oil. As long as its clear/colorless.

Hi all, we want to use a cellular phone as a "switch" to control a multimedia show. We thought of a cheap sensor that must be able to detect electromagnetic waves through a store window. We thought of phones because everyone has one in they pocket, phone is simply the source of the field. Idea is that customers can move their mobile phones in front of our store window to control a multimedia show in a simple way (forward, backward, pause), so in the end three or four different switches glued to the window would perform as a "control pad" for the computer. Maybe there is a way to base this project on products readily available which can be remodeled. Thanks for sour suppport and ideas! Nomax

I'm a teacher, and I have a little (but not a lot) of money to spend. I'd really like to buy something like a Quizdom voting system, but with anything up to five classes of 26 running at once, it's just not financially possible. Which got me thunking... AM radio transmitters are cheap to build right? I've seen one using a 555 timer and an NPN transistor - these cost pennies - use to transmit voice. Could I instead transmit a BEEP - or high tone or something - each timer on a slightly different frequency? And have a single receiver which then listens across this frequency range and identifies which frequency is transmitting the tone or signal and feeds that back into... PC, Arduino, Raspberry Pi? Range would only need to be like 5-10m.

So i got a bike when i was littler, and it was just a $25 cheapie bike from Walmart. Well I didn't like riding bikes much, and it was left to stay in the garage forever. Until recently. I've started getting back into riding my bike, and i'm wanting to use it to ride around town. However, this bike, being cheap, is hard to ride. Probably harder than it would be if I got a full-price one. However, being 17 and only being able to get part-time jobs, I certainly don't have the money for a full-price one yet. Is there anything I can do to this bike to make it easier to ride, or more efficient? Thanks!

Hi everyone i have been wanting to make a geodesic dome for a while now and i dont want to spend money ond conduiting which looks easy to do and all the angles associated with timber domes seem over complicated so i thought that pvc/ plastic pipe might be cheap enough though i find the hubs extremly expensive so i thought up a design that is in between almost all homemade hubs. the center of the hub is circulat like the pic and the bolts potrude at all apropriate angles then on the bolts is a rubber sleeve that snuggly fits into the inside diameter of the tube you are using then when you tighten the bolt the rubber is squished and pushes outwared on the tube so the hub stays on the tube just thinking that someone here might be able to improve the desighn and or make it. thanks for your ideas.

I was briefly entertaining the idea of making my own power supplies for some electronics projects. Everything I see involves the basic two step process of: 1) Use a transformer between the 110V mains to bring the voltage down to the level you want, 2) Use circuitry to smooth out the current from AC to filtered DC. However, when I went to price transformers, I quickly discovered that to buy a power transformer rated to hook into 110V AC, the transformer alone would always cost significantly more than the cost of buying a full ready-made power supply of similar output. You can't buy a transformer rated for 110V for under $20-30, but you can find thousands of cheap wall-warts (transformer plus AD/DC conversion circuitry, plus connectors) for <<<$10. Or, if you look at higher wattage units, you find similarly rated (for volts and amps) power transformers cost $30-100+ dollars more than full power supplies. How are these cheap power supplies made for the prices they are sold at? What am I missing here?

I'm trying to build a sensitive pinpression device: one that can see 3d digital images. The device would be able to read, record and organize the depth of each pin. I think the first problem to overcome is figuring out a cheap way to measure pin depth. I think it will be best to do this with rotation sensors. Does anyone know how to build or where to buy cheap rotation sensors?

If you were to take two model rocket motors and remove the secoundary charge (that pushes out the payload) from one and possibly fill the rest of the cartrage with homemade propellant. if you put one cartrage ontop the other and secured it with a little tape, would that work as a two stage rocket. does anyone think that the flame would travel into the secound cartrage and the pressure would blow out the first cartridge. Just wondering if anyone tried this before and is still alive and happy.

I am thinking of building a fish tank out of clear PVC pipe, and I need clear PVC. it would need to be at least four inches wide, preferably six to eight inches. I would need probably about ten feet, the more the merrier . Does anyone have any, or do you know where I can get it cheap (and by cheap, I mean under a hundred dollars)? thanks!

*EDIT* IT WORKS!!! Hi everyone, this is a simple DIY snow machine. It utilizes external mixing which not only increases the production but also eliminates the risk of water backing down the air line and vise versa. I will not be making an instructable but possibly a video displaying its qualities. It only needs an air compressor with the standard quick connect end and a regular garden hose. It works and I may be selling a few on ebay for ~$75 each and will include a professional looking instruction manual. This produces a very large mist and i have yet to measure its snow making capabilities. I expect it to make about 2" per hour over a 200 square foot area. Please comment and rate!!

Dear all, recently I commissioned and received a portable-ish movie projection unit that will let us show movies almost anywhere - in back yards, against buildings, in parking lots, and so on. It's designed for a guerrilla cinema experience for the community. See here for more information and a cheesy video I made for it. However, there remains one big issue: The screen and its frame. This is for the occasions we won't have a white blank wall to use. Can you geniuses come up with any suggestions? There are a number of features that are necessary in both elements:- 1. The screen Lightweight Cheap-ish Rolls up Doesn't easily crease, dent, rip, etc Isn't easily damaged by a small amount of fog/rain Can accommodate up to 12ft wide 16:9 images 2. The frame Lightweight Cheap-ish Can be quickly and easily disassembled to be carried short distances Is adjustable in terms of height and length (not essential, but would be nice) The screen can easily be attached to it Do you have any ideas as to how this would be possible? If so, I'd really appreciate it. Thank you!

I know a 93 year old in a rest home. When her daughter threw her out of her house (really!) she didn't get one of her hearing aids. The one she does have is marginal. Buying new is *really* expensive, and she doesn't have any money (related to the process of how her daughter threw her out of the house -- she cried every day for 6 months. No kidding.). I don't have the thousands it would cost to make it right.Recently we gave her an old cassette player and some cheap headphones. She loves it because she can really hear the contents of the tape.I'm looking for a simple device, reasonably small, that has a microphone and can drive the headphones with adjustable volume. I'm thinking small (mp3 player size, not hearing aid size). Any ideas?

I'm doing a project where I need a device that can launch multiple programs from shortcuts on the desktop without a mouse or keyboard. I'd usually just get an external numpad and map the shortcuts to that, but the programs use the number keys, so I wouldn't want to map shortcuts to anything on the numpad. I'm not exactly sure what to look for, but searching for "programmable keyboard" only returns a few (totally overpriced) results. Does anybody have any ideas? It doesn't necessarily have to be pretty, but that's always a bonus.

I convert engines from weedeaters, leaf blowers, etc. for use on large model airplanes. I use an aftermarket electronic ignition on the engines. The ignition uses a Hall effect sensor and a magnet to trigger the CDI ignition. I would like to build a digital tachometer that would use that same trigger. They sell them for $25.00, but I thought it would be fun, and cheaper, to make one (or several) myself. Can anyone help with a circuit and parts list? Thanks!! vettebob

Hi all, I'm part of a project where we're making soft sculptures to cover a tree trunk. It's for a sustainable festival, so we have to be mindful of re-using and recycling in our artwork. The problem we're having is with stuffing. It's only a temporary artwork for 5 hours so I'm not too concerned with waterproofing, but trying to make the sculptures look good when stuffed with shredded newspaper, plastic bags or chopped up old clothes is difficult. I'd really appreciate any ideas you can suggest! Thanks.

I want to clean and reuse my washing machine water to wash clothes. The system must be #1 cheap to build(off the shelf parts), #2 cheap to use(wasting power to save water is stupid). I am thinking, an easily accessed fine mesh lint trap. A second stage to remove chemicals (sand?charcoal?) and a third to kill any buggies (UV light?). I will also need to address which products are best to use for this system. And of course a valve too return to the "normal" system for some occaisions. Thanks for any input . nursenary

Whats the best (and by best I mean cheapest) calling card I can get that doesn't have an expiration. I only need 30 or so minutes. I want to be able to call international (middle east) from my cell phone (T-mobile prepaid) without being charged ridiculous amounts. I want something that i can leave in my wallet for a year and not have to worry about it being expired when I need it. The picture is totally unrelated, its a windmill

Hello I'm a Peace Corps volunteer working with coffee. I'm helping farmers improve the quality of their coffee. To do this they need to dry their coffee very well. It is hard to tell if the coffee is dried enough without a moisture meter, and a moisture is very expensive. Does anyone know of how to build a moisture meter? this tells what percentage of the weight of the coffee bean is water, I believe. Or if anyone knows where to get one inexpensively, that would also help. Many thanks
