Good material to work with for small electronics
« on: Mon, 02 July 2018, 11:41:25 »
Hi all, I'm currently looking for materials that are good for small scale electrical applications. In general these would be no larger than a 60% keyboard, but I am keeping options open. I am thinking that LEGO might make a good base product as it is electrically a conductor, easy to build with, and lightweight. On the other hand, they can be expensive and have some flex for larger items (like a keyboard). I'd like to avoid specialized tools if possible, but if the circumstances call for it, I do have some small tools like a Dremel that I could use. Any good ideas for what to use? In this case, let's assume I want to make case for something the size of a HDD.

I proxy anything including keyboards (キーボード / 鍵盤), from both Japan (日本) and China (中國). For more information, you may visit my dedicated webpage here: https://www.keyboards.es/proxying.html

You can get general purpose enclosures (project boxes) for hobby electronics in most sizes for much cheaper than building things from LEGO.

Otherwise you can build boxes easily out of balsa wood using only an X-acto knife, a steel rule and a cutting mat (and some glue). They wont be rugged by any stretch, but will be fine for office type environments.

another alternative is building boxes out of plastic sheet and strip stock used for model building. These just require the same tools as balsa boxmaking, and can be made pretty rugged if braced correctly. In addition, plastic enclosures can be sanded and painted to any level of finish you may desire.
Autocorrect is my worst enema.

Hobby boxes aren't that great for my needs, unfortunately. However, balsa wood seems like a really good material for what I want to do, I'll have to look into it further. I even thought about just using some scrap wood, but I really don't have the room for cutting it down so I kind of ruled it out.

Balsa is extremely light and not that durable. RC-Planes are often made of balsa as it is so light. But if you crash them, they will brake...

I am thinking that LEGO might make a good base product as it is electrically a conductor, ...

LEGO is ABS (like keycaps or monitor enclosures) so its not a conductor, its an insulator....

As I have no idea what you are trying to build I can't recommend a material.
And if it should be plastic and you can't fabricate it, get it 3D-Printed in your local hackerspace or on a website like shapeways  ;)

I meant not a conductor. Oops.

Well, i am not a great specialist in electronics, however i think that you actually have to seek for specialized tools. You see, we will not be able to advise you anything as long as we do not know what do you want to do. Which are your purposes. I didn't know what you actually want to do, however just like the guy above, i thought about the project boxes. Taking into consideration that you need something related to electronics, you surely needa circuit card. And in case you are looking for kind of a great project, i think that you would have to look for someone good in circuit card assembly. In case you will tell us what do you really want to do, we would be able to help you for sure.

Boy, I miss Blaise170. Who would have thought it?
For those awash in anxiety and alienation, who feel that everything is spinning out of control, conspiracy theories are extremely effective emotional tools. For those in low status groups, they provide a sense of superiority: I possess important information most people do not have.   For those who feel powerless, they provide agency: I have the power to reject “experts” and expose hidden cabals.   As Cass Sunstein of Harvard Law School points out, they provide liberation:   If I imagine my foes are completely malevolent, then I can use any tactic I want.  
The GOP’s challenge is how to harness that Trump turnout without, well, Trump himself. Because it can’t be stressed enough, the hidden deplorables aren’t Republican or even conservative. They have no ideology other than the ideology of destruction. Their life is ****. They want to bring down everyone else to their levels.
