I made an instructables about salt and water etching https://www.instructables.com/id/SALT-AND-WATER-E...as I learned it in a jewelry class, so I never tough about been unsafe. I posted it as I tough it was a nice one to share, but I'm having some comment on how it should not be safe using stainless steel in this project. As I don't have absolute knowledge about this before, and I just report what I learned, I was wondering if that was correct or not. (I know sometimes people comment very random stuff). Anybody know something about this topic?

Yes i know there has been a question about this already... but im asking it again. Can you etch a pcb with bleach? I dont really want to go out and find ferric chloride or hydrochloric (muratic) acid :) I just wanted to know if this would work. Also pros and cons would be good too, if not possible i can find a place with the right chemicals.. :) Thanks!

I know that copper is a better conductor than tin or aluminum. But one of my friends a few days ago told me that instead of etching his layout on copper, he used the bottom of an altoids tin. he said all he did was sand the bottom until there was no paint of the altoids can and then he etched his layout. (Chemical bath, toner, etc.) So my question is, Does anyone know how to etch custom layouts (toner layouts) on tin or aluminum? **I figure this could save people some money and time on some projects. :)

To print out a pcb circuit you need magazine paper, a transparency or photo paper. Well I was just wondering if I can just take magazine paper out of a actual magazine if its a blank page and print right on to that and then iron that on to my pcb?
Question by Kante Tech 6 years ago | last reply 6 years ago
I want to use press-n-peel thati use with the PCB's I make, to etch small detailed parts for model making, out of brass. What would be the proper ratio to mix Muratic acid with h2o2 so it will not eat away the mask material. I cover the back of the brass sheet with electrical tape, to protect the other side
I found this website for the etch-o-matic and thought how cool. I also thought that this has to be something really really easy to make myself if I knew a little more about it. So I'm wondering if anyone knows how to build one of these or if there is already an instructable that for this that I just couldn't find, or if someone knows of another source for further info. If anyone even just knows the generic term for this process that would be a help.I'm also wondering about the stencil http://www.youtube.com/watch?v=DjYio1YZuCA, is there another, more generic product out there that does the same thing? The development is no problem because I have an old blueprint machine that will do that part nicely. thanks a millionC

Hi all, I have a DIY boombox project made from a train case where I need a badge made to cover up a "mistake". I can provide an Adobe Illustrator, EPS, DWG, or DXF for the logo and shape of the badge. The finished piece will be 3.25" wide by 1.5" tall. As much as I'd like to do this on my own, I'm not keen on working with acid and don't have the time or work to build my own CNC or laser cutter. I will be happy to pay for time and materials as long as it's reasonable. Also, I'm in Northeast Ohio, if that matters to anyone. Thanks!

I am doing an engraving/etching for a gift and I want the lines and spaces to stand out from the metal in a more visual way. Please keep in mind that whatever material I use has to be able to stand up to standard pocket wear. I considered using a spray paint or enamel but I am not sure how well those would stand up to the pocket environment. Certain types of ink seem like they might be good until something wet touched it, but then would be a problem. Any suggestions? Thanks in advance.

Hi everybody, I just tried the Galvanic Etching process described on Jake Von Slatt's website. I wanted to show off my results and offer my observations.RESULTS:1) The etch came out perfectly.. even details that looked WAY to fine to pick up came out clearly.2) The Inkjet Paper (Staples Photo Plus Gloss) took a bit of soaking to get off, but when I got a corner, It came off as one single layer.3) I had to re-iron the corners, so check those before soaking.OBSERVATIONS:1) a PC power supply worked fine for the etch.2) my Root Killer lists Copper Sulfate Pentahydrate... no noticeable issue with this versus plain copper sulfate3) Copper Sulfate Pentahydrate eats alumin(i)um... Using tin foil as the anode was a bad idea.. I went through three anodes over the course of the etch... next time I'll use copper.4) Electrical tape makes a great mask to cover the back and edges of your etch.5) Mr Clean Magic Eraser's make short work of the toner without marring the brass.and now.... the Picture. (this is before paint, polish & varnish, I haven't gotten to those parts yet)

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...

I want to put together an electroetching rig (as detailed here), and I already have a battery charger, but I need to make the controller (diagram attached).

That just seems really clunky to me, and my gut tells me there's a better solution that is not "go buy a laboratory power supply". I have nothing against old-school, but this looks positively prehistoric. Anybody?

I built a power supply using a 25.2 volt 2 amp transformer to use for etching projects. It worked on my test plate but then started blowing the 1 amp fuses I was using with it. I switched to 2 amp fuses and it works but my transformer is getting too hot. I have experimented with different amounts of solvent and different size plates, which definitely makes a difference, though my 1 amp fuses are at most lasting about 10 seconds. I have read about building a control box with a halogen light and a variable resistor to control the amperage, but would it allow me to take some of the load off of the transformer? And if it would work, how would I connect it to my power supply?

Hey guys, Im starting to build a 2 axis CNC for a laser. I was going to try the DVD burner laser and just cut through some paper for now but im wondering what the capabilities of the higher wattage lasers are. I know there are several 1-2+ watt lasers on ebay, what could they mange to cut through? Could I cleanly cut cardboard? What about vinyl for making stuff like decals and stickers? Im wondering if spending the extra money on a better laser would be beneficial or not so if anyone has some good comparisons or ideas let me know. Im on a tight budget for this build so a co2 laser is WAY out of the question. This is my first CNC build so its mainly to learn but the more capabilities of the CNC the better.

Hey everyone! I'm in the process of etching my first PCB. I have a few questions. I'm using the toner transfer method, with hydrochloric acid and a little hydrogen peroxide as an etchant. Anyway, I transferred the toner to the board, but I believe the glossy paper I used may have been a little too thick. The toner transferred correctly, but i can manage to get all of the paper off. I've tried a tooth brush and a soft towel. My question is, if I just go forth and etch the board will the paper dissolve with the copper on the board and give me a clean result anyway? Will the copper covered by the paper not be removed? are there any cons to this? (such as not being able to reuse my etchant) Thank you all, your help is appreciated Ken

I am currently trying to find a solution to a year and a half long problem I've been working at, and was hoping the community could help me out. I ma trying to create miniature armatures that will always have the right proportions by etching the 'skeleton' out of thin brass (I believe it's somewhere around .02 inches thick). I've tried toner transfer and ferric chloride etching, but I am not getting steady results with the toner transfer. Since this isn't a circuit board, are there any other techniques I can use to cut through the metal quickly? If it's something along the lines of a CnC machine, as long as I can make it to cut down on the costs, I'm open to the idea. Just to give you an idea of what I'm trying now, at the moment I'm making stencils that I will spray acrylic or spray paint through onto the metal to allow for the same design every time. Acrylic and spray paint are also resistant to ferric chloride. Thanks
Question by ajpaulette 8 years ago | last reply 8 years ago
Hi! I plan on some experiments with a modified method i saw here for PCB-plating with copper to make the holes conductive. Now the question: What if my metal is not 100% pure but has some impurities in it? Does it still only "transfer" the copper and leaves the impurities as slag behind? I think it should be this way, since a similar approach gets used in refining metals to a very high purity; but i am unsure... Lets say i do: Follow the basic recipe (with smaller ammounts!) @ http://www.thinktink.com/stack/volumes/voliii/consumbl/cplatmix.htm and use copper sulfide. I think the trick now is that only copper-ions get disolved in the copper sulfide and nothing else. Those ions become plated to the other pole and thus i get purest copper plated to it?

Hey Everyone, Recently I have been looking at different C02 laser manufacturers to see if there was anything that was affordable but still of professional quality, and I stumbled accross Full Spectrum Lasers. I am wondering if anyone on the site has any experience with their products and their customer service. The reason I am asking is because their prices almost seem too low; comparable Epilog lasers seem to cost at least twice as much. I know that Epilog is probably one of the biggest names in the industry and have apparently been around the longest, but I don't see how that alone could cause such a price difference. So basically, if any of you have had good or bad experiences with Full Spectrum your knowledge would be greatly appreciated. Nathanael Scheffler
