Hi /diy/ I asked this question on /g/ but they sent me here because they thought y'all might be more knowledgeable on the subject I'm a frequent of /k/ wondering about comms and how they work. I was thinking about getting a short band radio to communicate with some buddies while innawoods to "train" But I realized I know nothing about them and wouldn't know the first thing about buying one- SO
How does a short band radio work? Would a CB suffice for a guerrilla force attempting to operate against a much larger/well equipped military? Is... Comment too long. Click here to view the full text.
There are commercial off the shelf items you can buy with encryption. Look for digital radios, analog is not encryptable unless you cypher it somehow.
Of course this being /diy/ I have to suggest a /diy/ solution which would be software defined radio. Can do analog or digital on the fly and you can choose your own encryption or modulation. Not really something for a casual user but there are some pre builts that probably have enough documentation for someone to use
>>989158 1. Get in with your local hams. Yes, you have local hams, and they can tell you all about the radio netwrok that exists around your locality and how not to inadvertantly infringe upon it, which could result in fines. Get your ham operator licence. 2. If you invest in something with off the shelf encryption, ensure that the encryption is actually secure/programmable, not something that can be googled or is found in the equipment's manual.
>How does a short band radio work? By short band, do you mean UHF or VHF or what? >Would a CB suffice for a guerrilla force attempting to operate against a much larger/well equipped military? You could communicate with each other, but everybody would be able to hear you >Is it possible/easy to encrypt a CB to prevent unwanted listeners? It's possible, but I'm pretty sure it's illegal, although the FCC doesn't give a flying fuck about what happens on CB... Comment too long. Click here to view the full text.
I'm interested in woodwork and have a few projects I would like to start in my home as practise to really get into it. I have experience with saw machines. I would like to make furniture and other small things. What machines and handtools are a complete must for starting my own hobby workshop in my garage? Also what are good brands? I already own a hand saw, every type of "bolt/screw turner" you can think of, hammers etc. Also the only machine I currently own is a sandpaper machine and a drilling machine(it's shit though and I need a replacement) Sorry...

I'm making a project where I'll be using a lot of 3W LEDs, from various colours. As so, each colour have a different tension to be used. I will not buy a LED driver module, so I decided to build something similar to the pic related here. I was drawing mine, but I ran out of time.
Anyway, the question is: I want to adjust the brightness of all LEDs together, but every colour is under a different tension, controlled by an LM317 (or some similar, doesn't matter for the question).
Does a simple potentiometer before the regulators... Comment too long. Click here to view the full text.
>>999544 Seriously, did you even read the datasheet? The circuit for an lm317 current regulator contains the lm317 itself and a single potentiometer. Just adjust the potentiometer to adjust the current.
No, my dear friend. You are the one that didn't read what I said.
The potentiometer that you are referring to is the one to correct the tension of the output of the LM317. I am aware of it, and that is exactly why I am using these.
My question is, considering the LM317 adjusted to 2,6V, another one to 3,6V and other 3 to 4,1V, how could I control the intake current of all of them together, so all the LEDs are regulated together, from zero volts to the desired tension adjusted on the LM317.
I want to add chicken wire to the bottom of our garage side door to keep any animals out.
We are cleaning our garage and our side door that we are blocking with a shelf has a 3-4 inch gap on the bottom for safety (exhaust buildup, etc). We were given a roll of chicken wire and were told that we should attach it to the bottom of the door to keep any rats, possums, etc out.
But I'm in a bind as to how to do this because I'm a moron. Would I want to glue the wire to the door? Are there bolts to bolt it on? And would i just leave it hanging on the bottom,... Comment too long. Click here to view the full text.
>>999363 Use 1/4" hole Hardware Cloth wire not, chicken wire. Chicken wire is the worst shit ever and rusts out inside of two years. Use screws with large washers to install it. If you are drilling into metal, use self-tapping screws.
So I got this Briggs and Stratton 3.5HP engine with a vertical shaft from a lawnmower. I would use it for a project like a kart or drift trike but then my best option is to convert it to a horizontal shaft. As I don't have a lot of experience with fabricating, I'm looking for other ideas. The thing is, I can't get that thing off where the blade is supposed to be connected to. So I can't really use 45 degree gears.
What material/substance should I use to fill 4x7cm holes in the shed roof to ensure a nice airtightness when constructing an effective chimney flue? I will attach an illistration to help describe what I mean... I am talking about the gap caused when you place corrigated iron on top of a brick wall.
Also, any top tips about chimney flues? Aside from the obvious like making the chimney exit higher than the ceiling of the room/building by about 1/2 ft
>>999068 Did you recently buy the tin? I'd say go back and see if they have anything. Menards sells a foam strip that fits underneath the corrugations on their sheets. If not fiberglass insulation would probably be a good bet.
Also your thread will be around for days no need to bump
Ok so my good ol' recliner is showing its age. The Mechanics and fabric are fine as I do my best to keep them in nice working order and clean. However the foam rubber in the seat is drying out and is literally crumbling away because of the springs rubbing against it. I fear it may soon ware its way through the fabric.
I've come up with a solution of gluing cushion foam to some vinyl shower pan liner and then stuffing it over the springs. The liner should be strong enough to resist ware from the springs for a long time, but I don't know what type of glue... Comment too long. Click here to view the full text.
I have so many battery powered lights that I'm ruining my wallet every time I have to get new ones. So I came up with an idea to connect all the lights to the power outlet. Where should I start and how hard is it gonna be? I'm not so gifted on this subject. (most of the lights require 3xAA batteries)
Cigarette box Hey diy people of 4chan, I've saw this thing and would love ro build it on my own but i can't figure out how the opening mechanism could work. It should rise when the box is opnened but how to connect the all those parts that they work together? Can you help me? And how is that type of opening mechanism even called?
Basically the big box looking faggot on the top is attached with a hinge to the base, and to the top cigarette holding nigger. Each of the cigarette holding niggers is attached to each other via those metal-rod looking kikes, so the top faggot only need to be attached to one of the niggers.
So I've been tossing around an idea in my head after seeing this guy. He got a nose bridge piercing, put magnetic holders for frameless lenses on there. I want to do this, but without getting a piercing or magnetic implants. If I put a little neodymium magnet on each side of the nose, would the attraction be strong enough to hold the glasses on through the bridge of a nose? Never really toyed around with them but I hear word they're really stronk.
>>996818 I'm not thinking from a "look cool" POV, which is why I think using body modding to do it is stupid. Earpieces are an uncomfortable pain in the ass and they break all the fucking time. Just looking to avoid that.
It might work, but if the magnets were strong enough they could cause damage to the nose bridge. I would look into finding something to modify the nose piece so it would hold onto the bridge of the nose rather than trying to use magnets.
>>995563 Somehow get in contact with the set designer and ask does he have that sort of information logged somewhere? Whatever you are seeing on the movie screen is almost certainly going to be different than what it was like in real life. Ignore the hassle and go with whatever looks the closest.
trying to match a backlit led screen color to real-life value is fantastically complex and inexact - you can get the rgb value of each color from a(ny) picture easy enough, but paint irl always gonna look different, you can't literally live in a film.
If you got the swatches borrowed from HD already, or can obtain a pantone swatchbook somehwere, go to: >color.adobe.com - upload that picture, you can pick out the main color areas you need, then try matching swatches to the solid area color swatches produced from selection there,...

>It is possible to improve the power of my bike to not get tired when I'm riding? Ride often and commit to a high protein diet, this is more of a /fit/ problem. You can't make the bike to be more "powerful", unless you use motors, you can switch to a lower gear but the muscle power it is the same for the same distance. Maybe add a third wheel to reduce the effort to maintain the bike stable.
Trying to improve a bike is like trying to improve a spoon, you can change the design, but you're left with the same thing.
So I'm doing some ghetto carbon layup and I need a way to get a vacuum going on the bag that holds all the resin and parts in the mold. (Creates an optimal carbon to resin ratio and reduces waste)
With that being said.. I'm not looking to drop a few hundred on a dedicated vacuum puller like picture related. I've seen a few other methods, like a venturi system hooked up to an air compressor, but I'd also have to buy an air compressor from harbor freight or the likes. (Which means, more money spent)
So any suggestions?

Hi /diy/ I just bought by first router and got this popular Bosch 1617EVSPK model from a seller on ebay that was selling it $40.00 cheaper than Amazon. The item was described as brand new but I had my doubts as soon as I opened it.
I put a bit in it and tightened the collet chuck, just to get a feel of how this thing works... Now when I unscrewed the chuck, the collet nut came off but the collet itself, and the bit are stuck in the router.
The instructions say its a self-extracting collet chuck and NOT necessary to strike the collet chuck to free the bit... Any... Comment too long. Click here to view the full text.
>>998255 The "self extracting collet" is marketing speak, and you will still get shit caught from time to time. Just hit it with a piece of wood, its not going to be stuck so hard you will damage the collet
>>998184 >get a piece of scrap and really practice getting the spray correct So much this. When I got my first one I thought I would repaint an old metal toolbox that had super fucked up paint. First attempt looked like ass so I stripped it down and had another go. Still ass. Third attempt: ass. 6 times I had to strip that fucker down before I got it right.
Found this Cypress plank from the mid eighteen hundreds in the wash up line of our recent thousand year flood in the southeast. Other than the obvious and giving it a good coat of lacquer and leaving a little bit of patina, what would be some other ideas for this beautiful piece? Will check back after work on my lunch break now thanks in advance for any input.
>>997156 How third world of a country do you have to live in to grab a big stick and throw it in your car and call it a project?
That being said, it is remarkably straight. Some nice stain on that and maybe a rod through it and a nice square mount might look pretty nice on a wall.mits a bit big to be vertical' but horizontal over a television might look good.
>>997002 >Has anyone ideas how one could make nice pads like on Pioneer DDJ. Hmmm,,,,,, >Google image search for "Pioneer DDJ midi controller" >dozens of different models shown, from a couple hundred to thousands of dollars, all with different controls you may have to post a link to the actual model you are talking about

>>997124 Would be perfect if they wouldn't be so high, from videos I can tell they have a stability problem
>>997170 >you may have to post a link to the actual model you are talking about see pic related, all the ddj have similar push buttons accross models. I guess the large performace pads are silicone and the play, cue and onther buttons are plastic with thin flexible frame, pushing on the tactile buttons on PCB.

Hello! Not sure if this would be better posted in /k/ so feel free to tell me to fuck off elsewhere. I've recently started a new job as a maintenance fitter/engineer at a big plant that produces pre-cast concrete products. I'm looking for a multitool I can keep in my coverall pocket for quick fixes whilst doing my rounds of the plant. Multitool based on a plier design would be preferable. What do you guys reccomend?
Tldr: best multitool for maintenance fitter/engineer
I'm so sick and tired and creeped out by all the bugs and rats and other critters that live in my crawlspace. Also, the space under my shed has become a breeding ground for rabbits and other vermin.
What is the most powerful poison a layperson can buy? I want to kill everything that lives down there, so I want a good all-purpose poison that is simply incompatible with all forms of animal life. What are my best options?
>>995610 >so I want a good all-purpose poison that is simply incompatible with all forms of animal life Not exactly the greatest idea, but various gases are used for that and at least in some countries some of them are sold to normal people. Phosphine is one of the more popular options. A more diy option would be carbon dioxide, but I don't know how practical it actually is, since it's just an asphyxiant. The thing is that you need to bag everything so that the gas stays there and... Comment too long. Click here to view the full text.
How would I approach making my own portable flag pole that's A. Under $13 Then B. Disposable Or C. Collapsible in a way that wouldn't make it a weapon
I'm going to a Trump rally this Friday and it's going to involve a lot of waiting initially so I bought a 3x5 Gadsden flag to wave while I fend off protestors at the gate, but once I get to the front of the line TSA will be confiscating any thing that could be a weapon, any ideas?
