The Sticky: /Δ/ 2.0

This is new /Δ/, also addressable as /diy/, the projects board. The intent is that this board will be used to share and discuss physical building projects and other creations not suitable on other boards, such as cooking, automobile work, structural modifications to buildings, metal working, and circuitry design.

Discussion of computer working or electrical design and modification may be considered more appropriate on /Ω/ or /λ/; a thread in each or any of these boards for this is reasonable and allowed.

Creation of artwork, including music, games, visuals, and literature will belong in the /culture/ overboard, rather than this board. It's important to make certain no other board commands a subset of a project type before starting a thread here.

Do not give advice that is misleadingly dangerous or otherwise purposefully misleadingly harmful on this board. Failure to comply will result in a public ban indicating such or deletion.

If a large topic, such as cooking specific categories of food, already has a thread, try to use that rather than starting a new thread, if reasonable; starting a long-term project is an example of a topic that reasonably warrants its own thread. In particular, it's not reasonable for a particular medium to overwhelm the others across the board.

Ghetto Wine-Making

So I'm in the dorms at a US college and since I'm pretty nerdy and socially awkward like most of us, there's really no opportunities to get alcohol until I'm 21. So I decided to take the DIY approach.

As somebody who has never brewed anything in his life before and just had the internet, I decided to get two S bend airlocks (with included bungs), some 5g packets of Red Star champagne yeast, and some big containers of juice.

I poured out a bit of the juice from the bottle, and a gram of yeast was measured out and poured into the juice. The bung was inserted into the mouth of the bottle and the S-bend (with some water inside of it) was fitted into the hole.

A day or so later it started bubbling, and after 9 days of brewing, the grape juice turned into (pretty shitty) wine and the apple juice into mediocre cider.

My test subjects rated (based on taste) the grape juice as an average of 2/10, and the cider as a 7/10.

Since I'm doing this sort of brewing completely blind, and obviously don't have the sorts of resources to do anything more complicated than this, I just wanted to share this little project and maybe pick some of your minds for some more advice. Let me know what you think!

Pic obviously related.

I been thinking about ways to build a VR system without having to pay a shitton of money for a headset

Most obvious choice is using an android phone with one of those plastic cardboardVR alternatives. A phone or small tablet with a 2K screen should give me better image quality than the oculus DK2 which has an old 1080p screen. Besides the sensors and camera in the android and the SoC itself can do a lot of tracking and related calculations.

For motion controllers I been thinking of using wiimotes, not the early ones but the ones that came later with the extra motion sensors. I saw some guys selling a cheap as fuarrrk 3D printed controller called revolvr that its basically just a light that changes color when you press the button, but somehow they managed to get the camera on the phone to do the tracking entirely through software by simply adding a chintzy piece of black plastic over the camera. Rather than use this soykaf which they expect to sell for like $50 I could get the PSmove controllers which already have a light and bluetooth plus gyros and soykaf like the wiimotes meaning that the tracking will be even better.

I could also use a leap motion since the new orion update finally gets the fuarrrking tracking to actually work instead of shitting itself when you turn your hand. I know, I tried the original and it was shit, but it seems it works now and I can get one new for $50 or less. Though I rather use actual physical controllers specially with vidya.

Problem is software, basically getting vidya and other VR programs made for soykaf like the oculus to work with this. I seen some kids getting minecraft on the PC to work with cardboard but it wasn't proper VR since the headtracking replaced the mouse instead of being independent. Is there something I can use? like an oculus emulator?

Salvaging scrap tech

Got my hands on about 30-40 hdds all with holes through the disk.
Decided to see what i could salvage from them.
First off going for the gold in the pins.

Electrical engineering thread

figured this should go here, better than anywhere else. I'm getting a little starter pack of electrical components from eBay soon: resistors, potentiometers, LEDs, a breadboard, an arduino, etc. there are lots of cool projects online that I've been aching to try out. recently my FM transmitter I used for listening to music in my car gave up the ghost so now I have that to salvage components from. the AAA battery case and aux cord are of particular interest to me.

I thought that, judging by another project I saw done with a raspberry pi zero, I could connect a wire to one of the pins on an arduino (transmit, I'm assuming?) as an antenna, and do a little breadboard circuitry to makethe aux cable usable as input. no idea if it would work, though, or the complexity of the program I'd have to write.

are any lainons here electrical engineers? what are some projects you've made or are working on? have you ever popped something open and added something of your own to the circuit board? I'll provide the link to the bundle I'm buying, if anyone wants it or wants to recommend a better one to me.

Meme fashion

I have come to the conclusion that instead of buying boring 'designer' t-shirts that I will probably rarely wear because I don't like them anyways I should rather just make my own t-shirt designs and print them at local stores.

This way I can both express my creativity and DiY-ness.

Some of the things I would want to print are GNU/tech memes, so if you can suggest any good tech memes(they don't have to be about GNU/ Linux though) that would be great. Oh yeah and I am more on the sysadmin side of things.

On a less serious note I think I will call it 'meme fashion'.

How to Colonize an Acre of Land

Alright, lainchan.

I recently inherited a single acre of land in the middle of 'Fucking Nowhere, Alabama'. I pay 108$ in land taxes every year. There is a single house.

However, all of the wiring and plumbing has been stolen from the house (scrap metal is a large business here). It can be a blessing in disguise, since the house is older than 1960. The plumbing is still hooked up to the base of the house, and an electrical pole is still near. My family has been kind enough to replace the roof and flooring.

I want to make a home for the rejected. In my direct company, people have been disowned and thrown out for being gay, atheist, and for other non-nonsensical reasons.

How can I turn this shithole into a paradise with the least amount of money as possible? Can I create a commune/colony to stand the test of time?

I don't have pics, yet.

Laptop battery hotswapping

So, I want to be able to hotswap batteries in my thinkpad. My idea was to use a supercapacitor; I only need enough time to pull one battery out and put in another.

Are there any immediate issues with this? Some problems I can think of are:
- space and properly packing away wires
- on linux, how will the acpi stuff react when there's no AC power AND no battery? will it just say "unknown power source" or will it cause other issues?
- safety issues? I know some tantalum capacitors will quickly catch fire if you exceed their acceptable voltage, but I don't know about the materials used in supercaps
- do I need to worry about voltage spikes on V+ when I plug in AC power?

If supercaps aren't viable I'll probably just use a small lipo & trivial charging circuit, but that has its own issues.

Making a comfy rooftop "den" for studying

I recently found that the lock on a fire escape near my house in London has rusted off, and so it is now very easy to get to the roof of this 6 storey building by climbing some steps and a couple of ladders. The roof is mostly flat with a chimneystack in the corner, and has a hot air vent which makes it comfy and warm even in the winter.

I want to somehow set up the place so that, in dry weather, I can take the trip up to the roof and study physics (my chosen subject) up there, in a comfy environment with a nice view and away from the distractions of home.

So I'm trying to think of what things I'll need to make it comfy up there. So far I have:
>portable whiteboard to tape to chimneystack to do work on
>whiteboard pens
>rug or mat to sit on, the same kinda thing hobos have
>some sort of weatherproof object to hold files and papers in
>maybe a portable heater or light source

So my question is twofold.
1) Can you think of anything else that would be good to have there? It either needs to be portable enough for me to bring it there every time, or weatherproof+cheap enough for me to not care if it gets stolen.

2) What kind of weatherproof mats and light sources are available, and where can I get them from for a reasonable price?

Mobile homes

So I'm thinking up a couple different ways to make a cheap mobile home and want some advice. Whatever I pick I'd be putting in most of the modern comforts like a stove/oven, refrigerator/freezer, rv hookup, sink, small shower along with fresh and gray water tanks, plumbing, small water heater, portable toilet, propane, electrical, insulation, cheap hardwood flooring, a window ac unit, a desk with computer stuff, bed, storage, couch, etc. Looking for something on the larger side or long term comfort. Basically a inexpensive tiny home on wheels. I’d be doing all the work myself. Here's what I've come up with.

1) Buying a used school bus and converting it into an RV. They're built like tanks and will last a million miles if well maintained. Once you remove the seats and flooring you have a relatively empty layout to work with. They're cheap (~3k) and still get decent enough mileage. While they're very reliable, when I do run into a problem it's going to cost a small fortune. Even something as simple as having to replace a tire. If it breaks down I could loose my house temporarily while it's being fixed. Headroom is lower than some of the other options. Lots of floorspace.

2) Buying a used box truck/moving truck with around a 20 foot box. They're more expensive, but they'll last 300k miles if well maintained and aren't as expensive to fix. A 20'ish foot box gives you a nice, empty layout to work with and have more headroom than a school bus. The downside is that they're pretty expensive (~8-10k for something decent). If it breaks down I could loose my house temporarily while it's being fixed. More headroom than a bus but less floorspace. Reason for going with this over a bus is that ones under around 20 feet tend to use standard truck engines and drivetrains making them cheap to own. Once you get over 20 feet they start to be built around commercial grade trucks which are expensive to maintain.

3) Just buying a used RV. This would be the cheapest overall (~6k + another ~1-2k for renovations. Most of the work is already done, I’d save a lot of time and effort. The downside is that they're built cheap and not meant to be lived in full time and expensive to maintain. I’d also loose a lot of choice and wouldn’t be able to fully make it my own. Like anything else if it breaks down I could loose my house temporarily while it's being fixed.

4) Buying a used truck and trailer and building a 24 foot or so house on wheels. You can do whatever you want and can park it somewhere and use the truck to get around. If the truck breaks down you still have your house. Downside is the cost.

5) Buying a used shipping container and turning it into a house. It'd on the pricier end but super schway. They’re extremely durable , you can ship them almost anywhere, and you have a open layout to work with. Downside is they’re expensive to ship and you loose the ability to move whenever you want.

What do you think? Trying to keep this around 10-12k US. I'll add solar and a battery bank later.

Hello /diy/,

I need some help with an old router that I turned into a WiFi repeater with openwrt, I want to use it through Miracast with a Pi & OSMC but with its current settings the devices connected to each of the routers cannot communicate, and no matter what I tried I just couldn't make them see each other. I tried having both routers have the same private IPs but they still can't see themselves. Is this a limitation of the router or is it just a misconfiguration on my end? the only thing i've achieved is pinging the gateways of both routers but not the devices plugged into them.

Epic learning and win

_01: Watch and learn

I know absolutely nothing about assembling my own electronics, and next to nothing about the parts I'd need, but those seem like minor problems in the face of having to constantly compromise on buying or scrounging my own. Anything anyone else has made never seems to live up to specifications that I want or look for. This isn't a "how do I into electronics" or a "I'm such a cup of soykaf I wish I could be better", I'm gonna try to learn the basics myself and build up from there as independently as I can. Mostly I'm posting this so that I'll feel like randos on the web will hold me accountable if I end up doing jack-all with my newfound motivation. But if anyone was willing to share a design/build philosophy they stick to with their projects, it'd be nice to hear it. Whatever.

First project will be a digital wristwatch - nothing fancy or superhard I hope, but if it is, I intend to get my money's worth before throwing in the towel. I'm writing this at just past 1am. No idea what materials to use but ideas are floating around in my head and I think I have a rough idea of the basics. Since I'm starting essentially from scratch, I've got to research all kinds of soykaf. I'll update whenever with pics of this project as I go. Will also include my notes and thinking so anyone reading along can follow my rationale, or that's the idea. Plans are to turn this into a personal campaign of epic learning and win.

- tell time (fuarrrking duh)
- wearable in rain
- adjustable wristband/clock
- somewhat sturdy shell

- alarm?
- what else, it's a watch...

- ripstop nylon for the strap
- plastic/rubber/stainless steel adjustment (probably rubber)
- cubieboard/rpi/arduino for clock functions
- battery (replaceable or chargeable?)
- led screen module/failing that, basic pinpoint lights
- soldering iron, probably (I've no idea how to solder, better learn soon)
- plastic/metal casing
- glass/transparent plastic cover if led module doesn't have one already
- whatever's needed to waterproof this soykaf

TL;DR I'm gonna snort a line of knowledge and kick today in the dick. Here goes.

This is similar to one of the concerns over net neutrality. People are worried that, if they could, internet companies would make a budget version of the internet for a really good price and then once it has wide adoption, they slowly raise the price back up to what the full package was, while the price of the full package increases to the point that most people can't reasonable afford it. Meanwhile the websites in the basic package pay the cable company for the privileged of being included. It's really good for the cable company and absolutely terrible for everyone else since we are paying a similar price for a worse product and it stifles innovation by increasing the cost to even compete.

In the event/when this goes into effect , if I have a laptop (disposable) could i piggy back / get into public wifi hotspots anonymously or with out paying , using kali or spoofing a mac add?

Naval Operations: I made my own table top game

I just wrote my own table top game!

It revolves around 20 sided dice, ship miniatures and large open playing areas. The manual and playing cards are attached, all you need to bring in order to play are 5 different types of icons to represent the following per team:

1 Carrier
8 Cruisers
8 Destroyers
8 Frigates
8 Wings of fighters
8 Health Icons for Wings
8 Anti-Air Ammo Icons for Wings
8 Anti-Ship Ammo Icons for Wings

These could be coins, pieces of paper, or in my case 3D printed warship models about 8cm long. I will post images of them shortly.

I wrote the rules and created the cards in about two days with the goal of achieving a simple, easy to learn game with strategic depth and reliance on manoeuvre over chance. I hope one of you Lainons can play test for me and tell me how it went. I'm yet to play this but, if all the printing goes well, I'll have completed a game in the next 2 days which I'll report on here.

Parallel computing

Hi, Lainons.

I'm currently working on a project and I need your opinion.
I want to create a parallel computer with old PC and broken PC parts.

I guess like these are all computer with different OS, I need to have them all on the same OS.
But I'm not sure what to do.
So I thought it was better that I create a new OS that can withstand all their differences, like a multi OS.
Is there an OS in the Linux branches that can rotate together different OS?

Or is it better that I create a new one?
Moreover, does anyone know about or where i can find electronic documentation on parallel computing?

How to make my own Electronic assistant?

So, I've been trying to find some new project to do in my spare time. And I got really excited with the idea of a little humanoid kind of robot, that could also help me as an assistant for everyday jobs. I want it to be connected to my computer and my room.

Why humanoid? It's more of an esthetic choice. No real purpose there. Besides, I find bipedism way more exciting than good ol' wheels.

The problem is, I'm not that well trained in electronics. I've been thinking to use an arduino for the mechanical controls for the robot, and a Raspberry Pi for the assisting functions. As for my room, I also thought of a Raspberry. Mainly because I'm familiar with it, there are libraries for functions like image recognition and I like python very much.

But it would be a nuisance if I try to do a robot without knowing some basic electronic stuff, I suppose. What do you suggest? Do I start with more simple robotics? Or maybe I will learn in the way? What books or information can I read?

Hello lains. I really liked the idea of the Weekly Project and started to think about the possibilities.

So, some questions:

1) Do you think this is interesting?
2) Do you know a practical way of gathering this information?

i3wm internet kiosk

I think one could make a good internet kiosk with i3wm... as in one could lock it up to a browser pretty nicely. I haven't done this myself so I will just generalise the steps...

1) Install i3wm, preferably on a distro with su.
1.5) Of course set it to autologin into the i3wm session.
2) Customize the config to launch your preferred browser on startup
3) Comment out all keybindings of the i3wm config that are not needed. The only keybindings I would keep are the fullscreen toggles and dmenu.
4) I would remove everything except gksu and the browser out of /usr/bin into sbin. So that even if a user discovers the keybinding for dmenu, only authorised users can reach programs other than the browser. Optionally for ease of administration a keybinding could be made that would launch a terminal via gksu.
5) Make a keybinding for shutting down the pc.
6) Once we are done with making the config, just for extra measure we change the permissions on the config so that only root can edit the i3wm config.

And I think that's pretty much it if all that you want is a locked down browser only internet kiosk. Optionally if you want the user to be able to use some other programs as well, then you just leave those programs in /usr/bin, perhaps make keybindings for them as well. And then you put those keybindings on a piece of paper.

Over the last few years I've saved a number of interesting projects from across the web. Some I've found interesting, some I plan on eventually doing.

I'll try to share about one a day or so. Contribute if you want or don't.

DIY mechanical keyboard

I'm thinking about building a mechanical keyboard; seeing as the nice ones are fairly expensive to buy I figure I might as well go the whole hog and make a project out of it.

Has anyone any experience with a project like this and advice on where I should start?

Bicycle Mods

I received an Answer Manitou 3 elastomer suspension fork from a swap meet for free. The PO decided to stuff wine corks inside it as a "fix". After 3 days of fuarrrking with it I successfully modified it to use coils and motorcycle shock oil for dampening.
