Salt and water etching

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?

Etching PCB boards

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. :)

PCB etching question?

I wanted to start making PCBs. However, I read that because the chemicals dissolve the copper, you can't dump it down the sink or throw it away because it is "hazardous" and should be taken to hazardous waste disposal. I'm still in high school and can't really do that and/or my parents would think I'm doing something dangerous. Is there any other way to etch PCBs besides using chemicals, like a knife or something?

Sanding Laser Etchings and Saltwater Etching Through Anodization ?s

I own an iPod Shuffle, 2nd generation, silver. It is very plain, and I've recently been reading up on saltwater etching. I want to remove the standard Apple logo from the back and etch my own text (it will either be "iMake" or "iBles", I can't decide). I've come upon two roadblocks, so far, those being: can I sand laser etchings (the Apple Logo) off, and can I etch through the player's anodization, or would I need to sand that off? I don't really care if it doesn't turn out perfect, or looks like a total mess. It's not like I paid for the thing. Thanks for any help!

Custom Etched Halloween Tombstone

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...

PCB etching left over paper

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

Use a 3d printer for etching PCBs?

Here's an idea - would it be possible to use a 3D printer to lay out the etch resist on a PCB?  It would likely only need to print a single layer.  Of course you'd need to use a material that would resist the ferric chloride but could also be removed without leaving a residue. Thoughts???

Can I etch a PCB in the winter...? Answered

I want to etch a PCB, but it is rather cold where I live. I had settled on the HCl/Peroxide mix, but I could use something else if need be. I wouldn't be worried about it, except I get the impression it's a good idea to carry out the reaction outside, where it is cold right now. If working outside in the cold is a no-go, is there any etchant that is "safe" (I understand that safety is relative, I mean along the lines not immediately gassing me) to use indoors with ventilation? If so, how much ventilation is needed? Are we talking an open window, or an industrial fume extractor? Also, I wasn't sure which category and channel would be the best, so if a mod or somebody sees this and has a better classification, go ahead and change it. Sorry for making this such a long question; I'd just like to be able to use my circuit board before I die ;). Thanks, dedgerton

Leah's etched laptop continues to be copied

I thought Leah's ad-supported laser-etched laptop was brilliant. When we were first talking about it, it was obvious that if she could pull it off, there would be a bunch of copy-cats trying to do the same thing. Obviously Squid Labs and Instructables are listed as sponsors, so I get a number of emails asking for further laser-sponsorship of laptops, and they always make me smile. Here's the latest, hope you enjoy the irony as much as I do: Dear Instructables-TeamIn the very near future I'll need a laptop for school. To finance that, I am planing to put Ad's onto the top of it.I am visiting a college of higher informatics. The school has more than 1000 students, teachers and other workers & visitors every day.My suggestion is a cheap way of advertising. The ad's would be laser etched into the top of the Laptop (made out of Aluminum). The Laptop has a size of about 40 by 27 cm (= about 14 by 10 inches).If you are looking at prices of an often-visited website for example, you'll get prices between 700 and 1000$'s PER MONTH for a little ad.For 1000$ you could cover the biggest part of the whole notebook, but you wont have to pay monthly. You only pay once, and the laptop will be used for 3 or 4 years. Also the laptop will be presented in the internet in several forums. I will post into a few forums myself, and make a little video about the laptop, and the company's that put ad's on it, and also other people will show around pictures of the project, because it's very unusual to do something like this.Of course you dont have to buy an ad for 1000$. Size, type of ad and therefor price are free of choice.I am looking forward to an answer !If interested, I could also send you some pictures how laser-etched things look like on a laptop and we could talk about data or prices if you are interested..

ASUS EeePC review and Laser Etching

Etching, staining, or wildly coloring plastic

I own too much plastic, that I use regularly, but want to decorate. Is there a SAFE method to chemically or otherwise "mottle" plastic with colors? Not looking to use paints, as those will just peel off. I know that plastics react to some solvents and such, but is there anything that you could 'wash' plastic with that would just outwardly alter the appearance? If I could get an "oil on water", or even just a "camo" sort of effect, that would be wonderful! (I tried searches for what to AVOID using around plastics without risking such an effect, but can't get the right search parameters...) Thanks for any ideas! I'd really prefer not to have to throw stuff out.

Results of Galvanic Etching UPDATE! 2 new plates

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)

How can I get my power supply to stop blowing fuses?
