I want to remove or lighten the colour of some artifical flowers. What dye remover can I successfully use?

 The artifical flowers are synthetic fabric. I have soaked in diluted bleach but there was no difference in colour at all. I want to give them a more vintage look.

[Requesting help] Need to dye a lens filter

Just wondering if anyone has any ideas on how I can take clear plastic and totally black it out I am trying to create a shaped bokeh effect in a uv filter for a more permanent setting than cut out paper (what most people do). Now I bought quite a few for different shapes or if I mess up. Last night I printed out on sticker paper a heart and placed it in the center of the filter and used Krylon fusion (spray paint for plastic) on the filter. It took quite a few coats to get it so light never shined through. When It looked good I peeled of the heart sticker and half the paint went with it. An obvious failure. What im trying now is, I took that filter and scratched it up a bit and I found some super glue and just thinly spread some across the lens (to hopefully give the paint something to grip to) let that sit over night it was too late to paint. And today I am now putting a few coats on it and i plan to actually cut the heart shape out of the filter.

Help! How do you do the acid-eaten clothing effect used by places like Lip Service Clothing? Answered

I accidentally tossed my favorite, and only, pair of solid white pants into the wash with colored clothes, and now there's a stubborn blue streak/splotch down one leg and on the hip. I've bleached it numerous times, but it hasn't budged, so I fear I may have to dye them- But before I take such extreme measures and have to kiss my white!pants good bye, I thought I might just... destroy the blue and create a nifty effect as well. So, does anybody know how to do the acidy-holes effect (Even if it doesn't actually use acid) used by places like Tripp and Lip Service on 'post disaster' styled clothes? a link for reference, not my flikr. http://www.flickr.com/photos/84816093@N00/2914162433/ Any help would be much appreciated!

How can I color aluminum wire without annodizing?

I bought a spool of 14 gauge aluminum wire for chain maille. My goal is to have alternating black and natural colored rings used for the maille. In a household metal working book I found from the 80's, they said to,"Mix 2 tablespoons lye into 1 quart cold water. Add aluminum part for 1-2 minutes. Submerse part into household dye mixed according to manufacturers directions until desired depth of color is achieved. Rinse in cold water".I tried this method using RIT black household dye; however, it was not successful. I am trying to dye the wire both RED and BLACK. If no method for the red is found, I can purchase a short length of anodized red wire; however, If there are any chemical reactions for turning the wire black, that would be great. Thanks!!

RGB LED interface with arduino

I need to drive 5 3W RGB LEDs in series using an arduino. The maximum current required is 350mA each for R G and B dyes. and minimum current requirement is 2.4V, 2.4V and 3.5V respectively. What should I use to interface the LEDs with my arduino as the output current of each arduino pin is 50mA maximum Thanks in advance

Any ideas of how to change the colour of diffused LEDs, can they be painted or dyed in any way?

I'm currently doing a project involving LEDs and want to be able to get the colour of them to match into my colour pallette, which is quite metallic and pastel, so I was wondering if there is any way of taking white LEDs and then changing the colour. Would something like glass paint be ok, or any kinds of dye that people could suggest? Any hints, tips or suggestions would be greatly appreciated. Thanks :)

How do it change a battery appliance to run off a wall plug when it has no built-in power pack outlet?

I have an alarm clock that runs on two AA batteries (I'm not fond of radio plug-ins they buzz too much). So that I can sleep easy and not worry about the batteries dyeing in the night, how can I hook it up to a 240v ac/dc power pack and what size pack would I need? (I have access to heaps of p.packs but I have v. little electronics experience. I have the idea but not the know-how!) thanks for the help

LED Music Submerged in mineral oil. Answered

I have seen led music cubes and prisms here but is it at all possible that you could make one that does light up to music in a plexi glass cube but filled with mineral oil? If I were to do this of course itd have to be sealed water tight so nothing leaks, but is there anything else that might need to occur? Per say would I have to add a dye to the mineral oil to get a good luminosity effect or would it be shining bright without it? If you could throw me some things that might be flawed in this idea or advice I would appreciate it lots!

Any ideas for achieving a Bakelite appearance?

Hey guys. So I'm in love with Bakelite, but not with the price of the raw material. I also want to form my own projects with a Bakelite aesthetic and don't want to deal with shaping such a fragile material. My question is: does anybody know of a recipe for making Bakelite? I also don't have much in the way of workspace or tools, which I'm guessing makes the manufacture of real Bakelite rather difficult. Because of this I'm willing to settle for something that isn't Bakelite but has a similar appearance. Any ideas about how this can be achieved? I've thought of maybe adding sawdust, dye, and finely ground plastic into clear resin, but I'm not sure if that would really look like what I want. What do you guys think?

How to I heat fabric whilst on the wearer without cooking the Model? Answered

Basically I've had this idea for a catwalk project where whatever garment I make will heat up on request and therefore trigger color changes in thermochromic ink which I will use to dye the fabric. Like the Rorschach mask project, but perhaps using a lilipad arduino to control the heat. Thing is I don't want to cook or electrocute my model!  My questions are: 1) What fabric would best conduct heat/not fry the lovely lady? 2) What components could I hook up to an arduino to create heat? 3) If the model sweats (the stage lighting will cause her to perspire) will it damage the circuit and therefore shock her? Help! D:

Can the large amount of sodium acetate decrease the stability of the glow of TCPO?

Sir we had made the TCPO by ourselves and we used the dye DAPN(diaminp phenazine) instead of 9,10-bis(phenyethyl) anthracene and use the solvent ethyl acetate for this and procced as your procedure but we didnt't get the glow for minutes.It lasts only for seconds(i.e. 3-5).Is this due to the use of DAPN rather than the use of anthracene? We had made the DAPN with the mixture of OPDA(orthophenylene diamine) with Distilled water and the addition of the HRP(horse radish periooxidase). We had used the amount as: 15 ml of Ethyl Acetate 1gm of Sodium Acetate 3mg of DAPN 3ml of hydrogen Pero-oxide 800mg of TCPO Sir, we are the student of Nepal studying Biomedical Engineering and we are doing our final year project and we need your help in this, as our project is based in the che miluminescece method for the pregnency detector.Please,please sir help us sending your reply.We will be very thankful towards you if you will be kind to us.Eagerly waiting for your reply.?

Electric Ukelele & Viola, Violin or Octave Violin Build

I am searching for inexpensive means to create aesthetically pleasing electric stringed instruments. I started this project when I started playing viola years after I was forced to quit private lessons. I discovered the F-f-fiddle on openfab.com which is a super rad 3d printed electric violin but since I do not have access to any 3D printer in the tiny town which I reside in, I sent the files to an online 3D printing business and they quoted me at least $500 just for the Fffiddle body! I didn't even bother to ask for a quote on the electric ukelele which I want to print & build so badly as well. I am interested in this project so that I can possibly help low income public school students in creating their own instruments to inspire them to take up an instrument and show them how much fun it can be to create something by yourself rather than buy. I am especially interested in acrylic plastic/lucite/celluloid, resins, exotic wood, recycled plastics, plastic injection molding, piezo pickups, and any other interesting materials that could be incorporated into these projects. I have been studying luthier tools, supplies, etc, along with design/fabrication of lucite/acrylic stringed instruments, furniture and other home goods. 3D printing/scanning, vintage celluloid guitar finishes, pre amps, recycling plastic bottles, landfill harmonic instruments, leather, pearl inlay, metallic finishes, enameling kilns, metal smithing, hand engraving & everything in between. I have been a mixed media artist for nearly my entire life and my father was a jeweler. I am going to find a way to create some functional and beautiful instruments no matter how long it takes me to narrow down the right combination of materials and how to make them, model them, mold them, dye them, etc! The photos attached are simply inspirational photos which I have collected over the past 6-8 months. Many of them are possibly patented, licensed, etc and I do NOT want to simply RIP OFF any of these photos! Please email me at svbacklund@gmail.com if you believe you could help me with my low income student instruments program or leads on 3d printing grants for public schools or anything else that may help me on my latest project or contact me directly via my instructables question here. I especially am interested in creating an electric violin which incorporates both classical and contemporary design. Any advice? Could you help?
