I love this website. I like the variety of products.

It would be cool if you also had someone explain a little about the internals of the product. I really enjoy watching these khan academy videos. Check them out for an idea of what I am talking about:

Everytime I see electronics like https://www.takeitapart.com/guide/81 , I feel like "shit, how incredibly precise have robots become". Those resistors on the last image, attached to the 3.5mm jack, are 0.3mm wide and 0.5mm high, and spaced together with next-to-zero distance. And yet, the pick+place process was exact enough that the components didn't just melt together. Awesome.

Most of the magic doesn't come from the robots, it comes from the soldermask. Surface tension from molten solder will move misaligned parts by a surprising amount:

Do none of the teardowns include text? Descriptions of how to do specific steps are super useful if any of the steps are tricky or hard to show visually.

I'm one or the TakeItAparts. I definitely agree that text descriptions are essential. The site is just getting going and we wanted to have some content on the site, but we haven't had a chance to fully annotate the guides. That said, the guide creation process allows you to add Markdown text blocks to each image (or video) as well as the guide itself, and images can be annotated with hover-over photo notes. The photo notes themselves can optionally be tagged as "components" (for part numbers), making salvageable or repairable components easy to search for and enumerate.

Hey Chris! I wonder if you remember me. I wrote the post on the Compaq Presario R3000 back in 2006.

I'm glad to see you still have the website going and even got the .com for it.

We want to create a culture on the site that explains the engineering and industrial design concepts behind the items on the site. How to inculcate that imperative isn't clear, but we're starting with community outreach and then hope to lead by example (the Roku guide is a step in that direction).

We were at the World Maker Faire in New York last fall, and we'll be at the Bay Area Maker Faire in San Mateo this weekend [come visit us! :-) ]. At each Maker Faire we brought a supply of e-waste items that faire goers could take apart themselves. As they turned screws and pried access panels we explained what components do, and some of the design decisions that went in to the products. The reception was phenomenal, particularly among school kids (with a roughly even breakdown of interest between the genders). We are also reaching out to Makerspaces to spread awareness.

We're hoping that the site will evolve to provide a similar virtual experience to the one Faire goers experienced at the Maker Faires. Essentially, we want the site to show that it is okay to take things apart, whether to repair, to salvage components, or to learn. The hope is that the guides on the site, submitted by users, will allow anyone to "take something apart" without having to pick up a screwdriver.

Creating a new guide is as easy as uploading a bulk selection of images, and clicking "Continue" a few times. Basic image editing like rotation and cropping can be done on the site, and it's easy to include image annotations and tool lists.

Why does it say "Welcome to TakeItApart.com False" on the banner? Is it false that I am welcome? ;)

(I'm assuming it's a bug...consider this a bug report)

Very cool site. I've needed something like this for a while. I'll bookmark it, and when I have more time I'll be glad to contribute information about Logitech trackballs and some Asus Eee PCs which gave me disassembly trouble a while back!

It would be cool if it had some sort of exchange for the individual parts after tear down. For instance I have an old smart phone with a broken lcd, but I'm sure the other parts are working. If I could use this site to document the teardown and sell or trade the individual components afterward for something I need on current project, that'd be epic.

That's a great idea. Fulfillment could be a problem, but maybe we could just connect people who have parts with those who need them? The best we do currently is create Octopart links for hover-over notes that are marked as components.

That solder mask is cool, but placing epoxy dots before placing the component works pretty good, especially if a reflow oven is used anyways. Misaligned components at high-tolerance has been an issue with solder masks, and not all silicon based solder masks are CE-compliant. The time it takes to drop epoxy dots is less than the time to retouch and realign the component.

I used to program PNP and CNC machines back in the heyday of Cray, then moved up to developing the software to program PNPs and CNCs (shit, I've come a long way since then but still miss the sweet smell of lead in the morning from the wave solderers) improving "fiduciary" operations and increasing speed, accuracy, and feeding.

It's probably standard legalese, but I find it funny that in the TOS ( https://www.takeitapart.com/terms-of-use ) there is You acknowledge that (i) you own and are solely responsible for the content that you submit, post, or transmit And You grant TakeItApart a non-exclusive, royalty-free, transferable, sublicensable, worldwide license to use, store, display, delete, reproduce, modify, create derivative works from, p…

One of the TakeItAparts here. We're certainly open to refining our Terms if others have been down a similar path before and have advice. My personal belief is to grant the user permissive rights, but we still need to worry about liability. We're certainly open to revisions.

Could you use a Creative Commons licensing scheme like Stack Exchange?

Why does it keep refreshing the page?! 0.7082894736842106 f39efb125de9.js:922 "scaled container width: 566.6315789473684"

OP here. If you saw that on a guide page, that's an experimental script we're trying to rescale image containers to the viewport. A window resize would trigger a refresh. It's not clear if we'll keep the behavior. If you make an account, there is a profile option to turn it off (as well as the always-on hover over notes).

It would probably make sense to disable that effect on mobile--the constant address bar disappearing and reappearing mobile browsers do triggers a lot of refreshing. Maybe just listen for orientation-change events instead?

Very cool site otherwise, keep it up!
