Should I post? (Well, not exactly)

So, this really isn't whether or not I should post an iBle, but rather how many of you are interested in it. I'm using the saltwater etch tutorials here and am going to etch my iPod shuffle (2nd generation). The etch will say "iMake" and if all goes right, I should begin to etch sometime today or tomorrow. So, I'll try to take quality pictures and all, and if anyone happens to have any tips for me, they would be appreciated! ;-) Thanks!

"Massively Reduce Laser Etching Time"

The guys over at have been addressing a way to reduce the cost of laser etched/cut projects when having a job done or reduce the wear and tear on one you or your company owns. It's not really a hack or a hardware fix, just an exercise in thinking within the operating parameters of the machine. Really well done and explained in such a way that others will be able to apply to their own projects. Well done fellas!

I need your opinion....

Ok, so I am within about a day of etching my iPod via saltwater. I am going to attempt to just let the clip (backside) of it rest in the water, using contact paper to guard against water damage to my circuit board. That is one option. The other is to remove the circuit from my iPod, leaving just the case. I've never done this, but have a guide. Do you think it'd be worth it to dismantle the player? Any, and I do mean any, suggestions are appreciated! Thanks!

Teach me a bit about lasers

Im in the process of piecing together parts for a 2 axis CNC and I would like to use it for laser cutting/etching. Since I'm new to building CNCs and I also dont have a ton of extra money I plan to build one using a DVD-r laser (200mW?) and just do some tests to get the basics down and play around with it. I would love to be able to cut 1/4'' acrylic as I have some laying around and I love some of the projects possible with it. What is the cheapest laser that is capable of cutting clear 1/4" acrylic? I have used a 40W co2 laser and it flew through the acrylic like it was nothing. Is there something for <$200 that would cut it?  And is it something that you can just use a lower power and go super slow or do you need the power? I did some light searching and didnt really find what I was looking for but if someone has a link to some helpful info I would appreciate any help I can get. Otherwise ill just spend my days cutting and etching paper!

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???

best (inexpensive home) tool to cut thin brass cleanly?

I've been etching brass for a couple years now, but need a better way to cut and trim my plates than a hack saw and a straight edge... What's the best power tool for getting straight edges on thin brass plates? I've been thinking scroll saw or band saw, but I've been told that band saw blades will walk. would a scroll saw be a good idea?

The Human Machine

It isn't that long ago that explaining human physics and behavior was imagined by copper etching. This picture seems funny to us now. But 100 years ago this was the way to explain the functions in the human head. I found this picture in an old book and I want to share it with you. This is nice for silkscreening or transfer print at T-shirt or any other surface. When you want High-Res 2208 × 2732 and 300 dpi let me know.

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!

Is There an Etchant-Resist That Can Be Left On PCB As Insulator?

Howdy is there a kind of resist that can be left on the pcb after etching (except the solder points), as an electrical insulator? can it be used with the photo-etching method, or only heat? thanks

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. :)

Laser etching photos on wood

I am using an epilog 40 watt laser to etch photos of animals on 4 x 6 pieces of wood such as cherry, maple, and bamboo. In the final product the image lacks luster and the "wow" look I am wanting.  If anyone had advice as to improving the processing and post processing, please let me know.  If I need to apply a coating in post processing, please recommend one.  I tried Olde English but wicking became an issue and the image became too dark.   Any advice will be appreciated!

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)

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

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...

The Etch-o-matic process

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, 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

What material can I use to improve the visibility of etchings/engravings?

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.

Need someone to etch and cut a piece of aluminum for me

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!

Knife with glass and Silver handle

Hello Everyone, I'm new to this forum and I have made something I wanted to share and get some feedback. This is "Art Knife" I used a method I invented to etch hardened glass with colored images and made some into what I think is a pretty cool knife. The glass is held in place on a nice Damascus blade with a Sterling Silver frame. The etching can be of any subject, I chose the animals because they look nice but I could have put a portrait or other designs on my knife. I also want to use this technique for other fine items like memorials, awards, etc. The etching never wears because it's covered in a layer of Pyrex glass by baking it in a kiln. What do you think of this idea? Any feedback greatly appreciated! Cheers, John

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

Asus, a sponsor of Instructables, has put together WePC where they are asking for input on their next generation laptops. As part of their sponsorship, they've asked my opinion on various aspects of laptops. Most recently ASUS EeePC review and Laser Etching.As part of this campaign, Asus was kind enough to lend me an EeePC. I gave it to an intern at Instructables, Matthew Dalton, who was really excited to try it out for note taking in class, and general portable computer usage -- his review follows below. Since I've been writing about how important it is to customize your laptop, I also asked Matthew to give the EeePC a laser tatoo, and you can see the results were beautiful! Matthew' review continues here.Finally, I'd like to know what you have thought about this Asus campaign. If you would be kind enough to take this survey, I would really appreciate it.

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.

So anyway, I cracked open an Etch-a-Sketch and got aluminium powder all over my desk. Can anyone help?

When the top half of the case finally snapped off, a cloud of fine aluminium powder was ejected over a large area of my desk. I'd like to clean it up soon, (read: before my Dad gets back), but I can't figure out how to get it off. A light brush from a paper towel smudged it into a nice shiny streak, and blowing doesn't get near enough of the particles off. Would water help or make things worse? Anybody else have experience with this?

Can someone give my PCB design a once over before i etch???

Hi everyone, hoping someone can help me here. I have designed a pcb in expressPCB and was wondering if someone with a bit more knowledge and experience could give it a once over for me.  I just want to be sure there are no errors before i go away and etch this. The design is based on a 30 channel ambilight tutorial that is here on instructables.  It uses two TLC5940 chips that are connected to an arduino.  I have left the arduino pins on the design unlabelled as they connect slightly different on each arduino (mine is a mega 1280). Here is the design.  Please be gentle, i am just starting out with pcb design and have no breadboard at the moment. :)

Do ATX Power supplies convert AC to DC power?

Hello all, I am sure this is a silly question for the experienced, but seeing as I'm just starting to really get into this stuff, any help would be appreciated. I am writing to get a bit of consensus to assure myself the a ATX power supply will convert AC power in to DC power out.  I would like to save myself the hassle of taking apart a computer if this is not the case.  In the event I'm wrong, what does convert AC to DC power? Just to give you an idea of what I need this for, this power supply will be used to run the electrolytic etching process for use with copper in a copper sulfate bath.  I'll be using the etch process to etch through copper plates (saves a lot of money compared to ferric chloride) The last question I had is if anyone knows how to discharge any residual energy within the ATX system.  I have an instructable on converting the ATX into a power supply, but I feel like I read the residual power in the system can be quite nasty if it shocks you, so I'd like to avoid that.  In fact, any suggestions would be welcomed. Thanks! Andrew
