reloading.jpg
56 KB,
I'm sure this thread has been made 50000 times so I'm sorry in advance for wasting space on your board, but I've been wanting to find a constructive hobby to subside my urges to kill and keep me busy. I was considering reloading as I'm already an ammosexual but I don't really have the disposable income to drop a couple thousand dollars on a respectable reloading kit. So you guys got any suggestions and/or tips on how to get started?

Hey I'm trying to program a digispark arduino to produce a joystick output to usb, but the documents and tutorials don't seem to really explain how to use it.

They have this example code:
http://pastebin.com/spVJxZGP

Specifically I'm talking about those DigiJoystick.setX() functions. Just from looking at the function in the master file
>void setY(byte value) {
> last_built_report[1] = value;
> }
The <byte> argument doesn't seem to do...

>The <byte> argument doesn't seem to do anything.
Bollocks doesn't it.

You just listed above exactly what it does: it updates a data structure which gets read and acted-on by the USB library every time you call delay() or update().
>When I am using this function do I actually pass the <byte> datatype itself as the first argument?
Why would you ever need to tell a function what type its own parameters are? I think you need...

Holy shit, I just worked out what you're doing.

You're misreading the type declaration in the function definition as if it were an additional parameter.

When you say

int OPIsATit(int nosrsly)

That's only one parameter. The first token is the type (int), the second token is the name (nosrsly). If you want to call OPIsATit, you have to provide one parameter, and that parameter has to be an int.

ah ok that makes sense. I've just never seen typecasting where the type is in parenthesis like that. I do code in other languages, but I'm really only just learning how to program arduinos for this project. In any case that really explains it and, yeah a bonehead mistake.

I've wanted to learn a practical skill for a long time, shitty minimum wage job and wasting my life away never accomplishing anything. So I decided to start with something simple.

I bought a Weller WLC100 a few weeks ago, not sure where that stands on quality, but it was affordable. Today picked up some solder (Nexxtech light-duty rosin core) and some de-soldering braid.

I think I have everything I need to get started, though I keep seeing mention of 'flux' but I think Rosin core doesn't need it? correct me if i'm wrong, I'm here to learn.

I have a few Electronics to work on, and possibly some throw-aways I could practice on. My goal projects are to fix a loose power jack that's fallen off inside of a waacom tablet, (Thankfully there's a really nice guide for the specific model and everything) And then I have another power jack on an old laptop that probably needs to be replaced entirely as it no longer receives power, so that one's probably waiting on shipping.

The last one I'm not sure if it's feasible with what I have, but i'll ask anyway. I have an old Dell alienware wall outlet cord, The Wires are broken and exposed and I was wondering if I'd be able to melt them back together with some solder, or if that's even a feasible option for conductivity etc, If this is a ridiculous notion go ahead and laugh at me, I'm a newbie so I have to ask somewhere.

Oh yeah, my soldering iron didn't come with a sponge, can I use a regular household sponge? How about work surfaces, is my pseudo-wood desk fine as long as I don't set the pen on it?

Please give me as many pointers as possible, links to tutorial videos, good resources etc, thanks in advance senpais

Yes. Google wire splicing methods and pick what suits you. Heat shrink tubing for insulation afterwards.

Yes. Household is fine. So is a paper towel, or your sleeve, or your trousers. Don't burn your house down. (An iron aint THAT hot.)

yes, cut off the damaged areas, trim off from the good areas, insert heat shrink sleeves, solder, heat shrink, wrap in tape to protect, done

no dont use regular sponge. use kitchen towels with a tiny bit of water. it works great.

>work surface
literally doesnt matter at all. even if you put down your iron it should be tipping up because the handle should naturally rest the iron above the surface.

>>947544
you dont need flux unless you are doing small smd shit or plumbing.
solder isn't mechanical fix so you shouldn't solder cables without extra strain relief. use crimps.
solder sponges with a hole in the middle make it real easy to clean quickly against the edge so the gunk goes in the hole. also bath/washing spponges don't hold water as well as solder sponge. dont know why. once you wipe it clean you should tin the tip to keep it wet

usually pencil will balance so its not burning anything....

can I fit a brush cutter attachment to a Victa Tornado 26cc line trimmer?

I've noticed ryobi has their expand-it attachments for their line trimmers that fit many other brands. I was hoping I could just buy their attachments and fit it to my line trimmer. or can I just swap the line cartridge for a brush cutting blade? I was looking on the stihl and husqvarna website and their units have all manner of fancy blades. I am trying to hack back many over grown bushes with branches about 1cm thick. just because the garden has grown over its boundaries and 1m into the lawn...

you don't want to run a brush cutter on the bendy shaft, it needs a straight shaft and gearbox to handle the torque.

if you're cutting wood instead of reeds and weeds stick with an 80 tooth blade, the three and four tooth blades bounce off instead of sawing.

i don't know if victa and ryobi use the same shaft coupler, you're just gonna have to try it.

so i've got a 2004 grand am gt that had a stock "Monsoon" stereo system, i replaced the stock head unit with a pioneer and that worked just fine since there's a stock amp in the back

but now i've replaced the rear speakers, 4 wired ones, with 2 wired JBLs that are rated for 300W each. the problem is, the amp is only powered for like 200W, and when i go up to a certain volume they start cracking and making bad noises.

I was planning on just bypassing the amp and wiring the JBLs straight to the head unit, but the head unit is only good for...

anyone know if you can use a heated o2 sensor to find the % o2 content from ~20% to 95%?

or are they only valid for low concentration exhaust?

Afaik car sensors won't work at that oxygen range.

If you're ok with tedious and somewhat inaccurate off-line measurement, you could just burn the oxygen away from a known volume of gas. A classic chemistry experiment uses steel wool, but sulfur works too.

Depends on where you live. As long as you can prove its safe, structurally sound and meets all the code requirements you shouldn't have a problem. Out here we have people building with unreinforced cob, straw bales, all kinds of shit. They built them with permits though. Not many places that require permits are real big on you doing shit without them. Its mostly a property tax thing. They can't tax you for it if they don't know you've built it. That said, most places have a permit exemption if its...

I also bought an arduino a couple years ago to get started with electronics and let me tell you what I've found out: it's not the same thing. Yes, you'll learn a bit of electronics because you'll have to build the circuits to be activated by the arduino, but you're mostly doing programming. I particularly find that pretty cool. I feel comfortable enough to try some basic projects and have enough knowledge about logic and programming to do some research and improve my skills.

I totally recomend you get an arduino with some sort of starters kit. They're cheap enough for a begginer and tutorials (if you actually do them right) are pretty comprehensive and you can only go up with both your knowledge of programming and electronics.

anons here are coming to slap you because they don't think you should lurk for ideas for your projects (which I agree, gets a bit annoying after a while), but you'll need a project to learn your stuff, because it gets pretty boring to just learn to do a couple examples.

My recommendation here is sparkfun, instructables, popular mechanics, and some other diy channels like that. There you'll find a lot of ideas of all skill levels and you can choose something to do. You'll also have a chance to look around code and circuits, which is the best thing for learning how to do stuff.

Look around. Don't be lazy. Don't think you know your shit, you can always improve in the same project.
