3D Printing in the UK?? Answered

I was shocked by the postage prices for Ponoko ($80 minimum on a $7 part) is there anywhere in the UK that will let you print one off items with small minimum orders. Or any way I can get something printed and keep the cost under £20?

can someone help me implement the Australia Post DRC postage calculator into my website?

Hello, i am starting up an online store , on behalf of , where i or rather "we", will sell things to raise money for the community vault! so far ive had no issues with building my the store into my website, however, now that i am up to writting up the listings, i need a template to copy off which each listing for each item will reside. each items page must show the price of the product, and the shipping cost . now heres where the problem starts i have no idea on how to implement the postage calculator from australia post, into the template, so that all items pages display the shipping cost depending on thebuyers location, so that anyone anywhere can buy from the site, and not just people within australia, and areas i need to pre-research the shipping price for, which will become inconvenient as the site grows. there are instructions for doing this on this link however, i dont know how to put this into my website, or how it works, as it requires a substantial amount of coding. what i need to know, is how to , using the provided code ,set the variable which is being set as the value of a text box within a form, to the shipping price of that area, when i click a button, also in that form, but not have it leave the page. although, i dont want some variables to be accessable by the person browsing the page, such as the weight, which i want to be able to alter within the source code of my hmtl file. all i want the buyer to be able to do is select their location, press a button, and have the shipping rates to that place appear in the text box. the shipping calculator is the only thing missing from my website. whoever can solve my problem will get a best answer from me!

How are postage stamps voided? Answered

Hello,  How do the UK postal service know if a stamp has been used before?, (Sometimes they do not have a postal mark across them). I think that it used to have something to do with phosphorous dots... um.... Thank you

Old flyback transformers

I really want a old flyback transformer for my high voltage projects, but I don't know where to get one. I tried to get one from my local TV repair shop, but they did not have any, only new modern flyback transformers and I don't want that kind of transformer. So if you have any old functional flyback transformers that you don't want anymore, I would really want to buy them from you, and I will pay for the postage price. I will buy modern flyback transformers if you are trying to give it away for a very cheap price or for free (I will still pay for the postage price). Please respond to me if you live in UK, if you don't live in UK, please don't respond to me because I cannot afford such high postage (shipping) bill.

Make a stamp disappear?

I'm planning a mystery dinner party. There will be a postage stamp on display. I have a way to trigger a lights-out remotely (just by plugging the lamps into a remote-control switch). During the blackout, which will last a few seconds until I can "find the fuse box," the stamp needs to disappear. I could of course just walk over and steal it myself, but I'm looking for other suggestions. Print the stamp with some kind of ink that will vanish if hit with a camera flash? Some sort of motor-and-string attachment that could pull the stamp into a hidden chamber in the display case?

Electronic Swap Program -- Intrest Poll

Muff and I are in t3h (hehe) process of trading a few parts, he sent me some stuff I needed, I'm going to send him some stuff that he'll need.Anyway, it brought up an idea: An Electronic Swap Program!It'd work where you'd send stuff that you have tons of to someone, and they'd send you stuff they have. This is really a great way to get stuff you need -- and the parts end up being cheaper, since you try to send parts that you have in bulk. (Its cheaper to buy in 1K quanities than 1)I'm just trying to see if theres interest. The plan, ATM, would be something like this:Send parts and $2** to me I use $2** to send you a mix of what people, and myself, have donated.You get parts and are happy. (happy or die!)**Outside of USA: I'd probably have you guys go online to our postal service's site, and buy the postage for me, and send it to me to print out. Or just send me more monies.(You end up paying postage both ways)$2 is just a guess on how much it'd cost. Muff's package to me cost $1.14 -- so $2 seems about right.If you're interested, or have a suggestion, lemme know!

Neon sign transformer

Hello everybody, I am looking for a Neon Sign Transformer (NST), I can not find any in my local area and cannot use ebay because I am 15 years old. So if anybody has an old used NST that you don't want anymore and willing to give it away or can obtain a NST for free from your local dump or neon sign stores, I would really want it! I will pay the postage bill. If you are curious why I wanted a NST, I want to build a Tesla Coil, I had built other Tesla Coils using other power supplies but I always have bad luck with them, they don't work properly so that is why I wanted a NST.I really don't mind how much voltage the NST gives out, like between 6Kv to 15Kv, but I do mind how much current it gives out, I only want a transformer that can give give out current between 20mA to 40mA, because of this, I don't want to build a big Tesla Coil yet...So, if you have a NST that you are willing to give away, please respond to me ONLY if you live in UK (United Kingdom), because I cannot afford such high postage (shipping) bill from other countries like America..

Green sand options? Answered

I finally finnished my testing prototype of my metal melting furnace. Did a few casts to get short rods for the lathe work and noticed a big problem. I used washed play sand as itwas the finest sand I could find locally. The result was good in shape but very bad in terms of surface quality. For another test I used the leftovers of my crushed perlite and mixed it bentonite and the surface was really smooth - but using perlite is not really an option. Real green sand is hard to get in my area and the postage costs for a 20kg bag are just too high on top of it. So, before I start hunting down all sand and soils shops nearby: Is there a proper name for extreme fine sand or a good alternative for a reusable casting media?

Member gift exchange?

I just heard about imgr doing sort of a secret Santa type gift exchange for valentines day and thought that was a super cool idea. While we're probably too late for v day, maybe that would be a fun thing to put together for a "spring cleaning" maker trade. There's a lot of amazing talent on this site and I bet some of us could definitely stand to clear our workbenches of surplus or unsold projects. Each person would get the name and address of another member and send something they make, and receive something from a different person in return. I'm happy to help organize it, but I'm not sure about the best way to assign gifts since we can't just draw names out of a hat. Suggestions? And do we divide it by country so nobody has to deal with international postage, or leave it wide open? I welcome ideas and definitely would like to gauge interest.

Water deionizer

Hi I was wondering if any one had a good idea of how to build a water deionizer.I'm just starting a car valeting business and need deionized water for final rinsing of cars to prevent water spots as we are in an ultra hard water area and normal rinsing leaves water spots no matter how well we chamois it. I have a 1000L IBC tank that we use to collect recycled and rain water which i want to use to rinse off the cars. As we are in a water controlled zone we have to recycle and filter our water and also it is a ultra hard water area the filters to deionize the water for rinsing cost around £90 plus postage and only last 10-15 cars which is to really killing our business. It is costing us around £9 a car to just rinse them and on a basic wash we only charge £10 which as you can see is not viable. Thanks in advance

Can a battery recharge itself? Answered

Hi there, i have a query. In a circuit powering just an LED can the battery power the LED an recharge itself? Or, having a battery power an electric motor connected to electric motor running it in reverse could that generate electricity to run the first electric motor? In my head i have this image in my head that the 2 motors wired together with a LED could power that LED and themselves from the battery connected for a short while then put back in its package? I'm not blessed with access to a reasonably priced electronics store (honestly, its cheaper for me to import the components from America paying postage to New Zealand than purchasing at the nearest store even through online or phone order) Anyway, so i haven't got the patience to wait 2weeks and spend many dollars to experiment myself i wondered if anyone had or knows if this sort of thing works?

Instructables Halloween Postcards

Some people send Christmas greeting cards.  Since Halloween is our favorite holiday, we decided to send Halloween greeting cards.  About 1100 of them.  Check out the pictures of signing, stuffing, applying postage, and mailing them. We sent them to top authors by number of Instructables, by pageviews, top commentors, people who have previously won contests, and others.  Since we did all this by hand (and had a couple of snafus along the way!), if you didn't get one, that doesn't mean you're not awesome; it means we screwed up and forgot to ask for your address.  But, we'd still like to send you one!  So, if you'd like a Halloween card, and you haven't already entered your address, leave a comment here by Friday October 23 and I'll send you the link to submit your information.  If you have entered your address but haven't received your card, it's probably still on its way. Happy Halloween! This is the forum topic for Halloween 2009.  If you'd like a card for 2010, please see here: 2010 Halloween Postcards.

Ignition switch for an electric bike in the UK.

Hi folks. Does anyone in the UK know a dealer who could supply an ignition switch/battery lock for a Thompson Classic electric bike? I've had a look around the interweb & ebay & cannot find a suitable replacement switch anywhere, there are plenty that would fit but none of them seem to be the correct one as they only have one "On" position the one I need has two, one is for pedal assisted & the second for fully powered. The switch also locks the battery box onto the frame it looks similar to the larger of these two on ebay. I have called the importers & their quote for a replacement carries an outrageous price compared to the third party ones I have seen at over eight times the price plus postage & although I expect to pay a bit more for a slightly more complex part I certainly don't expect it to be THAT MUCH more. I'm sure there must be other bikes that use similar switches but haven't as yet been able to find a dealer who can help. Any suggestions would be gratefully received. Thanks in advance for your help.

Really need a "Gearbest" 16x32 r/g LED matrix

Hi, new to this forum but Silvius' excellent work with this 16x32 matrix inspired me to join, mainly to thank him for his work: Anyway, I am working on a project that requires 3 of the LED matrix panels featured in this project. I ordered 3 but broke one of them (my inexperience) so I'm short one of these 16x32 panels. They were available here at Gearbest but they're now sold out. I wonder if anyone who picked one up for a project no longer needs theirs, or has a spare they'd be willing to sell.  I've tried a variation of this board but it's not quite what I need - must be the board with SKU/model 202393. I'm in the UK but I'd be happy to pay for the going rate for postage (and your time having soldered it!) as well as for the unit itself. "I'd see you alright for a drink" as we say here. Let me know what you'd want for it. I figure this is a long shot but thought I'd try! Take pity on a newbie, huh ;-) Thanks, Davey

UK based WEEE recycler - do you want any bits and pieces?

Hey there instructables fans. I've been reviewing your site for a while now, loving all the cool projects. I saw one project that was using some disused IDE connectors from a PC and it got me thinking.... part of my day job is running a WEEE recycling company in the South West of the UK. We process an awful lot of computers and although we re-use as much as we can of the computer stuff we recycle there is still a lot that goes to be shredded for material recovery. I'm always looking for new ways in which bits and pieces could get themselves a second life. Would this community be interested in any old computers bits and pieces? I'm not asking for money just enough to cover postage, perhaps some brave soul in the UK would like to take on a 'bulk order' and then distribute around? It's just a thought and my apologies if I've stepped on any toes or forum rules, I have no interest in making money from this just simply to get make a few small bits and pieces useful once again :) Please message back if interested!

Amazon voucher give-away - WINNERS!

I won a prize by posting a comment on a tool blog. The prize is a $10 Amazon voucher. Unfortunately, I can't redeem it on, and it would be swallowed by postage if I ordered from the US. So, I have a voucher to give away. To win, have a look at this topic started by Acidbass, and then post a verse for an Instructables boom-de-yada song here, complete with links (see the verse I posted there). Deadline: 4th December. Judging - the "best" verse will be selected by the capricious whim of Acidbass and myself. The winner will be announced in this topic, and receive the prize by PM. WINNERS! In reverse order: 3rd goes to Wasagi 2nd goes to RedNeckEngineer and 1st, with the prize voucher code, is.... GOODHART! Well done, that ibler! 2nd and 3rd get no cash prize, but Acidbass will include their verses in the video. Keep posting good ideas, though! I think the winner is Goodhart because he followed the rules made a catchy verse and had the guts to send me a recording of his verse that he made by himself to place in the movie. 2nd place is RedneckEngineer because he got creative with the verse. 3rd is Wasagi because he followed the instructions and did a very good job. The 2nd and 3rd place prizes are that their verses get to be in the movie :-)

Hi! I am looking for anyone who would be willing to give me any neon sign transformers (that are not being used or are unwanted) for free. I have looked online and everyone that I have found has been way too expensive.

I would be willing to pay for shipping as long as you live in the US for I do not have very much money. Also, if you are not willing to give me or do not have a neon sign transformer, I am also looking for oil burner ignition transformers and pretty mucj any high voltage transformers that can be used for high voltage experiments/projects.

For some I could salvage replacements from cheap lighters but not so much for the longer ones - the type to get your bbq or oven going. Here the wire from the igniter is in ne long piece going all the way from the piezo, through the long neck to the flame outlet. As the wires in those piezo igniters are aluminium it is next to impossible to attach a longer wire as usually there is no room for crimped connections and the isolation is a problem too. I also have one particular lighter that uses a slightly longer and thicker piezo igniter, the common ones don't work here as they are too short. Adding more support underneath is a no go as the shorter ones have less travel when activated. Last but not least is one lighter that requires a piezo with not just the little metal cap at the end but with a full metal body for the stationary part. The lighter in question does not work with standard types even if I add a little metal strip to make proper contact. Problem is simply put that like this the standard ones arch over and no spark comes out of the wire. So big question: Is there any supplier or Ebay shop where one could actuall see the various types of piezo igniters and order them in small or single quantities? So far I already struggled to find a source for the crappy standard ones and the only one I found wanted to charge $ 2.95 US per igniter plus postage. Sounded a bit greedy to me considering I can buy a complete lighter with it for around one single buck...

Finalists, please edit this area below the bar to add your own statement:Hi everyone, davidbuzz here! - Just adding my personal note here, (as instructed!). I think that my entry, which took two weekends to write (not including yurt building time of innumerable hours and 3 yurts), and includes nearly a hundred photos, and full details, is rather good, and really comprehensive. It's also backed up by the fact that it's already inspired at least 2 others to start building yurts themselves, which is fantastic. Thanks to everyone's interest, my instructable made it into BOTH the "top rated", AND the "most visits" lists prior to being a finalist, so it must be popular. Please vote for me to show that! (up-rate this forum post!)As for winning the laser-cutter, I can promise you that I already have 20 different uses for it in mind ... including finishing my CNC table and building a 'reprap' (google it), and I'll be sure to post instructables on the good ones of them for everyone to see too!. I'd also like to take this opportunity to offer the use of the laser cutter to any instructables members located in Australia, for the cost of the materials & postage ... if I win! Yes, that means I've just opened myself up to 22 MILLION possible users (the population count of Oz) ... so put your votes in NOW! Viva-La-Instructables!

Archaeology Student needs help with 3D scanning and printing

Hi Guys and Girls, first time posting like this so i hope this is in the right place, and if it is i can get some help. I'm currently studying Applied Archaeology, in the Institute of Technology Sligo, in Ireland, I'm in my fourth and final year and as part of this I have to research and write a thesis. The topic I am planning on doing involves 3D scanning, and if everything goes to plan, it will turn out great, and is something no one has done before in Irish archaeology, Ok so here’s the thing. It is still early days, I haven’t even decided on the title or gotten a chance to experiment with the scanner, and I am relatively new to 3D imaging and all that it involves. But as part of the overall concept of my thesis I would like to haves some of these scans print using as many of the various different methods of 3D printing as I can. This is so I can compare and analysis there suitability. This is where I hit a wall and I hope someone can help. There aren’t many companies that do 3D printing in Ireland and those that do usually deal with medium to large company’s and thus are way out of my price range. Edit: 21.09.2011 Ok after a doing a boat load more reserch I have been able to pick three methods of 3D printing I would like to use: 1. Fused Deposition Modeling using the, RepRap and MakerBot. 2. Laminated Object Manufacturing. 3. Stereolithography. If any of you out there have an interest in Archaeology and can offer advice on 3D scanning, image editing, has access to a 3D printer or are lucky enough to own one of these machines, and are willing to help me out I would be extremely grateful. I am more than willing to contribute what I can to the cost of raw material, cover the postage to Ireland and of course give massive amounts of praise and acknowledgement to all those that have helped, when I’m writing my thesis. Many Thanks Michael

Im starting an ebay gadget store. what are some cool fun things to sell?

Well technically ive already started, but now, ive made enough profits to begin expanding. At the moment i sell 70mw green laser modules (not pointer pens), carbon graphite rods 5/7/10mm wide at any length and from time to time i try and get rid off my liquid a$$ stink spray, though people tend not to buy that as postage is $6, and lastly long range, but very cheap, 433mhz receiver transmitter pairs . All of this , from within australia, i plan on selling things which are awsome, as well as generally inaccessible by many australians. Currently i intent to buy up 6v spark gap ignitors , identical to those on sparkfun, different coloured laser modules, titanium to weld to my MMO anode mesht cuts, more wireless receiver/transmitter pairs, though, this time, toggle/momentary ones, currently my ones are latching, i plan on buying small shockers, and lastly, Nitrates, Aluminium powder, sulfur, and all those chems which are so hard to find in australia. Also, i will start buying more, and in larger amounts, thermochromic pigment. I also plan on building DC-DC HV converters, for charging coil gun capacitors, (based on the instructable of the same name, once i get permission to use the schematic to base my design off to sell), small shocker modules (to make taser things from), Various oscillators, like flyback ones, 3D printing services and 1W regulated 808nm burner modules. Now, ever since i discovered the spark gap ignitor wholesaler, ive been thinking, "what else could i sell thats awsome and hard to come by?", but legal too, this is ebay after all. I would really like some help in finding things which arent especially expensive or big (im not buying stuff which costs like $100 a peice), but also things you would like to see sold in your local gadget stores. Really, just anything in this general catagory, stuff which is really awsome or very hard to get, either in australia or anywhere, but not illegal. like novelty gadgets, or things which do amazing things, such as mini spy cam bugs or something. I really need help, i know what kind of things I LIKE, and want, but not what others like and want. please help me out!

Ch. 2 In Which Many Packages are Shipped and a Fancy Dinner is Held

Hey Instructabrarians, SHIFT!  here.  Just keeping you updated on the exciting weekly activities at the Instructables HQ!  This week was relatively hectic, with a lot of planning on a bunch of stuff including Maker Faire 2011, Ice Cream Social Planning, shipping out new prizes, and of course NEW contest planning.  We finally got all of our iCreate Robot kits in, as well as an extremely large shipment of new Instructables T-Shirts in this week (now in Purple and Blue!). My fellow interns, Karen and Wade, and I were able to finish shipping out all of the fantastic prizes for not only the National Robotics Contest as well as the Eggbot Contest at our local PO (and it only cost a couple hundred in postage!) So Winners, be expecting a special delivery from Instructables HQ soon! Maker Faire planning is going well for us too.  Just received all of our tickets to the Faire, and I know Karen's been very busy preparing with upcoming interviews with all of the news teams that will be visiting the Faire.  And, as always Instructables will be selling some awesome one-of- a kind merchandise.  Which reminds me, better get DIY PIXAR ready too. And before I forget, Friday was totally awesome!  To celebrate our 10 millionth visitor to our website, we were all treated to a fancy dinner at Lulu's Restaurant on 4th Street, SF!  Food there was fantastic, everyone had a great time, and it was great to get everyone out of the office on a Friday night. As for me, I'm still adjusting to my work as a new member of the Instructables team.  There's always something new and exciting going on everyday and I'm still wrapping my head around all of this.  This really is the best job ever. Oh, two last things before I go - special treat for all of you, some special inside news.  First off, our upcoming public Ice Cream Social at our Top Secret HQ (conveniently located on 82cd Second Street, right next to Sammy's On Second) is going to be amazing.  If you've ever wanted a glimpse of all the behind-the-scenes stuff that happens on the site, come next Thursday, May 19th, for the public event and FREE Ice Cream!  Laura's actually booked a machine that uses Nitrogen to store all of the  ice cream and, yes, it is Cool. Finally, some brief new contest news. Earlier this week, I actually got to sit in a new planning meeting and listen in to all of the great new ideas Instructables has planned.  Now, as an intern I've promised my bosses not to spoil the surprise for you, so I'm bound by my word to uphold their confidentiality.  BUT, I can guarantee you that our new upcoming ones in the next months are literally the best  contests I've ever seen happen in my long time experience as a user of this site, and are quite unlike anything you've ever seen before.  So stay tuned, you'll be amazed. Anyway, that's it for me.  So until next week, SHIFT! signing out! PS.  I know I'm forgetting several people in my pictures, so, in advance, I apologize.
