Gelli plate substitute

Hi. there is a new craze sweeping the craft and art community with a mono printing plate called a gelli plate. It's made out of some sort of mineral oil or gel of some sort. (i think). It's a flexible, clear mat with a soft feel and a give to it, a bit like jello. There are plenty of homemade versions using gelatin. which works fine for a while but it soon breaks up or bacteria sets in as gelatin is a food substance. Are there any clever boffin types out there that can make a similiar product that doesn't use gelatin and that has a good shelf life. I first thought of Oogoo but it's not pliable enough. This Gelli plate reminds me of the soft silcone gel that is used for scar healing, but is so expensive for small sheets. here is the link to see what I am after. http://www.gelliarts.com/pages/gelli-printing-plate-demo

Small VERY Hot Plate

I am looking for someone who can design for me to make or make for me a specialized hot plate. I need it to be small like 3" by 2" and to get very hot as much as 700 degrees is desired. I want the power source to be 400watts. I know this seems hard but my reasoning is that the smaller size means higher temps with less wattage. I would use this as a hot plate that evaporates liquid from an airstream as it passes by - a dryer if you like. I would use 2 to cause the air to have to pass both in a zig-zag path. I would like to have a solid surface so eventually I see the plate encased in ceramic but for this it need only be metal. Can you help? Contact me here on the site to discuss more details Coog

Making a plate which detects contact with metal

Hello, I'm trying to make a 6" x 6" plate which can detect when a needle comes into contact with it.  The plate can be made out of whatever ( preferably an easy to obtain material like a metal sheet) and have any electrical components necessary attached to it but the needle can't have any attached wires etc.  Any thoughts?

Simple CNC question... Answered

This is probably really obvious, but I wanted to know if there is a better way.  I was thinking about how I would go about making a simple "mounting plate".  Then I realized that wouldn't I first have to cut it to size and then mill out the holes.  But then the since I had to cut out the plate it kind of takes the point out of the cnc, because I wouldn't be very accurate for the outside dimensions.  So is there a way to machine the outside, even though it would be in the cnc's vice? Thanks in Advance! AI

Things to do with LCD backlight guide plate and polarisation films?

I received about 15 damaged laptop screens and took them apart to get the CCFLs and inverters which I'll combine into a modest spotlight for video recording. From each laptop I also gained some films and the light guide panel. I believe one of the films from each is just a simple diffuser whilst the other two appear to also be blurry polarisers. Finally, each screen has an acrylic light guide which refracts the light 90° and does so evenly by having some kind of bumps or dots spaced out according to the "diffusion equation" so there are more further away from the source of light (which comes from the side).  Any ideas for what I might use these films and plates? I do have a lamp project for which I can use the diffusion film but the polarising films would probably absorb too much of the light.

Electoplating wood. CHEMISTRY QUESTIONS!

Hello guys, Thanks alot for reading. I don't know much about chemistry outside of my one high school class. We electroplated a penny. I have a 1.5ish square-foot piece of wood, and i am wanting to CHROME IT.... chrome paint kits cost hundreds of dollars, and i've before seen chrome-plated wood.. and i want to replicate the results. [img]http://www.eastcoastpowdercoating.com/liquid%20chrome%20guitar.jpg[/img]I'm looking for a cost effective alternative to expensive chrome kits (+300 dollars for a pint)In theory.... my method would involve somehow plating the guitar with some sort of metallic based paint, then submerging it in a chrome bath. [b]IS THIS POSSIBLE??[/b]Is there a metal chemical that can somehow be applied evenly to the entire surface of the wood? (i.e. paint?)What, and how much of the specific chemicals do i need, and where can i find them?I really want this to be mirrored. Thanks so much for your responses to my problem:P

I'm trying to make a Breast Plate

Hey, I'm going to build a piece of FANTASY chest armor. I'm not going for realism or authenticity. Just making "a pile of spikes" that looks cool in my opinion. I'm thinking of making something to the equivalent of a low neck line tank top out of leather / tight weave canvas, and then covering it in steel plates. I'm thinking of dividing the front suit into groups and bands of plate. So I'm going to have a set of bands from the right and left chest, then another section that joins them down the center. A section for the abdomen, a section for each side, and then similar sections for the back. I'm then going to bolt the shoulders onto their respective chest plates. So I've done a crappy sketch on GIMP, Kinda explaining what I'm going to do for the center line of the chest. I think If I do this right It'll allow a lot of flexibility, might even be able to see my chest expand and contract while breathing which I think would be a cool effect. Is there any reason why this wont work? But are there any key factors that I need to take into account when doing this? Parts that need to be more flexible than others?

is it safe to turn a kettle into a hot plate for boiling solutions?

Hello, i recently realised that my kettle, which consists of just a a kettle shaped container with a hotplate down the bottom, quickly reaches tempuratures in excess of 100 degrees celcius, and so i have considerd getting a second hand one or a scrap one at the local dump shop, to use in my chlorate cell, to periodically boil the solution once per hour to destroy the hypochlorite and re-absorb the chlorine gas which would normally be lost. i intend to remove the little hot plate! i also want to use it, along with some kind of speed controller, or lamp ambience controller or whatever they are called (lamp dimmer), to make a variable tampurature hot plate, using a heat dependant autoresetting circuit breaker to ensure the temp doesnt go above what i want it at. what i need to know, is  it safe, not for me, but for the kettle, to operate for short periods of time without turning off? or would the resistance coil burn out? by that i mean 5 -7 minutes, considering its normal run time is at about 1-2 minutes. or can it safely run on indefinately, with the only damages occuring being melting of wires and the base?

How would you imprint a graphic or text onto a blank aluminium or stainless steel blank switch plate cover?

I'm making a pedal board/road case with a buddy of mine. It's in its early stages, but it will consist of a pedal board and lift-away lid, covered in tolex with metal corners and such. I'd like to put some sort of small name plate or logo on the front end of it. I've found a blank switch plate cover, normally used to cover up spots where light switches or power outlets used to be, and by some means apply a logo or text to it. It's about the size that I'd like the logo/text to be anyways. I guess I could go and print a sticker and call it done, but I'm looking for a way to make this more permanent. It will be on the outside of what is essentially a small road case, so it will be up against the elements. So I guess if there was a good way to print off a design and put a layer of something over it so it will stay in place, possibly be shiny ( :D ), and be protected from the elements, I'd be all set! For the sake of aesthetics I've decided whatever plate I get, it will be some kind of metal. I've found brushed aluminium, stainless steel, and chrome.

Beginner Jewellery maker. Question about gold/silver plating

Hi there, I'm starting jewellery making as a complete beginner and want to use Metal Clays to do this as it seems one of the easier and cheaper ways to make jewellery at home. I looked into lost wax casting, but there are no studios or workshops near where I live to do this. I really love gold jewellery, and was wondering that if I used bronze, copper, or silver clay, am I able to plate it too? I've seen those electroplating kits online, but I was wondering if it would work after I've finished making my jewellery piece with the clay.  I've also seen videos about 'silver accenting' copper clay... Is this just basically like coloured base metal (costume jewellery), or is it real sterling silver (i.e high end costume jewellery). Any insight anyone can provide is very much appreciated! :) Erika

Can anyone teach me how to make a remote control plate flipper for my license/vehicle registration plate for a car show?

I have a car contest coming up in Indonesia and we have a choice to remove our plates to protect our identities on the streets from show visitors. It usually takes a small amount of effort to remove the plate screws and fix on the contest user name but I thought it would be nice to have it automatically change when I enter the show (might help me gain more points :D) I have tried to search for this item online but some only supply the item to Russia and the rest of the sellers are in China. They cost around 290 dollars for a set, which I thought was quite pricy. To be quite honest in that 290 dollars I was going to spend, I doubted that the China factory would use the best quality materials considering the price. So I was wondering if anyone could help me make one of these automatic revolving plate frames with remote control operation for the auto show? It would be really great as it would help me gain more points! These are the links of the Russian company and Chinese company that produces it: 1. http://www.plate-flipper.com/       They have videos (Russia) 2. http://www.aliexpress.com/store/product/AUTOMATIC-Automatic-Flip-license-plate-revolving-license-plate-frame-free-shipping/101548_517916045.html               They don't have videos (China) Thank you all for you help!!!

Geology in action: A mid-ocean ridge you can visit on vacation!

UPDATE Jun 2011:  ScienceNews has a very nice feature about Afar, with an excellent narrative summary of items since the current spreading event began in 2005. UPDATE Nov 2009:  Science magazine only keeps their news articles free for a short time.  The link below requires paid access to read.  Wikipedia has an article on the volcano. A news article in this week's (May 2009) Science magazine online reports on a very unusual volcano. Located directly in the center of east Africa's Great Rift Valley, it is spewing a unique kind of lava. The Great Rift Valley is a place where one of Earth's tectonic plates is actively dividing in two -- the eastern tip of Africa and the Arabian peninsula is separating from the rest of Africa. In several million years there will be a brand new ocean (not a "sea") like the Atlantic, and the Great Rift Valley will become its mid-ocean ridge. This African volcano is essentially an example of the undersea volcanoes that run down the spreading center along the middle of the Atlantic (Iceland is a set of them that are above the ocean surface). If you want to see what was happening when the Atlantic Ocean was forming, and Brazil was being broken away from West Africa, go visit Ol Doinyo Lengai in Tanzania. ADDED:  Besides the world's only active (on land!) natrocarbonatite volcano, the Great Rift Valley also has examples of sheeted dikes forming and breaking through to the surface.
