Considering buying a Raspberry Pi Zero since it's just $5, but I would like some opinions first. Are RPis worth it? What are some neat and/or useful things I could use one for?

If you need to ask, you dont need it.
If you really want one, just buy the pi 2 B on amazon for 37$

Youll be much better off.

I actually did think of an idea just now - using one as a home cloud server/torrent box with a 5tb external drive and owncloud or some shit like that. Would the RPi be well suited for this, or is there a better option I should be looking into?
>>
>>910628
A lot of people make seedboxes and servers with their RPI.
And again, you want the ram and power of the RPi2 over the 5$ one. You are going to pay triple the price of a Zero buying adapters to get it to run, at that point its only marginally more expensive to get the much stronger one with real HDMI and ethernet built onto it.

Hi /diy/,

This is my first post, so please forgive me for the mass amounts of autism.

I'm looking for a new couple of projects and want to give creating musical instruments. Thinking maybe a cello or guitar, something that will take time, but also be badass. Not looking for professional, just good enough for me. Also, wtf is sound/tone board? I've been doing some research and am lost.

Does anyone have any experience in building instruments? Or any plans they'd be willing to share?

Thanks /diy/

Cold weather general!

I just finished putting up thick plastic sheet over my windows, and got to thinking about my shed/cabin again.

What is a good and cheap material/s to insulate with? It has plywood walls and a small woodburning stove inside. My thoughts were expanded foam and emergency thermal blankets.

The "right" way to do it would be faced (better) or unfaced (cheaper) fiberglass or rockwool batts. Make sure your measurements are good and buy batts that fit your stud width/wall height/thickness. Faced batts are easy because the kraft paper/aluminized paper facing is usually wider than the insulation so you can lay them into the walls and staple up the edges alone or with little help. Then panel as desired. I would at least panel the area near the wood stove and add a further layer of something heatproof,...

cellulose might rot
rockwool is currently best for insulation
if you're doing it and you're unexperienced, find some earth wool from Knauf for example, which won't fuck up your health while putting them on

aerated/insulated concrete can also be an option, if you find a smart way to cast it

This would just go onto the concrete foundation. Worried it might heat too well in the summer but the greenhouse would be open with ventilation fans.

Is there any way to calculate the configuration of mirrors and what they'll reflect.

I've got a gas meter installed facing the wrong way to read it and it requires the meter reader to bring a extendable mirror to check it but half the time they cbf and over quote the bill which leads to a fucktonne of issues to fix it.

I'm thinking of placing mirror panels placed strategically with a togglable LED or something to check it easily, would this configuration of mirrors be readable, or backwards still?

Yeah, I'm just having a hard time because I already took time off after school. I feel like I wasted a lot of my life growing up playing video games and fucking around. Never gathered any hobbies or skills. I'll be 30 by the time I get my masters for physio. Not much time to be switching careers at that point. This is again why my friends advise me against it. Trades and tools and all this stuff is brand fucking new to me. I never did any of it growing up.

Hey /diy/, I recently found this old Kenwood KR-5030 in the basement along with an old record player so I figured I'd set it up, but when I turn on the 5030 the lights flicker and there's an arcing noise coming from where the power switch/speaker selector knob is. I'm not that good with electronics so I have no clue where to start with this thing.

Anybody know what's going on or how to fix it?

Hey DIY, looking for some help here on something that I'm sure is really simple

A switch for my fog lights in my car broke, and my car being ~12 years old I couldn't find the OEM switch. I ordered a third party one and it fits like stock, it just has these on the back instead of a female plug like the original switch. I'm assuming its the two wires plus a ground since there's 3 spots? But i'm not really sure which is which is the issue. Was hoping for some help in figuring this out.

Pics of the plug and oem switch are coming too.

Hey diy. I have heard rumors that there is a method of desoldering an entire pcb in a few seconds using hot air rework. Then you basically throw all your components in a big ice cream dish and you are set for life. Does anyone know how this would work? Maybe stick it in one of those toaster ovens and then scrape everything off with a knife? Or use a high temperature heat gun?

The solder on PCBs melt around 180 to 230 celcius, if you can heat the solder more than that, it will melt, and components can be removed, or fall off..

Heating an entire board to this temperature, is a bad idea, as most capacitors are not designed to withstand that, they are normally wave soldered. some components, especially larger ones might be glued to the board, then again no success, smaller SMD components will not fall of by them self due the capillary effects of the solder.

And finally, most components can be damage of excessive thermal stress, especially...

I am going to try and repair/Replace the RAM chips in a commodore 64B (breadbox, grey function keys) I have the chips and am going to replace all of them rather than checking which ones are broken. (only displays 900ish bytes of RAM) How would I go about doing this and what tools do I need besides a soldering iron?

That done, I also have a Commodore 64C that I've been using up to this point. what would you suggest I could do to mod and upgrade it? Since I have 2 and the 64B is the more classic design, I will keep it as it is.

All classic micros have a flat memory layout: a single address bus and data bus wend their way around the system, connecting RAM, ROM and peripherals to the same flat address space.

The C64 has basic bank switching, but all it really amounts to is a helper chip fiddling with some address lines to shadow the ROMs.

Write yourself a version of memtest86, step through the areas where RAM is supposed to be, and when you find the addresses where the RAM isn't working, that'll point you to what isn't...

AFAIK there was never a "B" model, it's just a plain C64. The "C" was originally "CR" for "cost reduced", but Commodore changed the name since they actually raised the price.

There's some mods for the audio circuitry, but other than that people mostly use external expansions, for compatibility.

Heat it and cut it with a chisel. Use a band saw, dremel, drill holes in the area you want cut and then grind it clean, temper it to make it softer for cutting, cut it with a torch, score it and try and snap it in a vice, bend it back and forth until it fatigues and breaks, cut it with an explosive shaped charge, slice it with thermite, mind bullets, corrode a line across it with salsa and a DC power source

the easiest + cheapest way to make rough cuts in metals is to use a 4.5" angle grinder with a cutoff wheel on it (pic related)

don't just buy ONE cutoff wheel, buy a dozen... or two dozen. They come in packs for a reason.
They wear down as you use them, but they don't cost much. and it's still way faster than sawing by hand.

also--wear leather gloves and use full-face protection. the grinding disks can break and fling pieces around at 50,000 mph
