Welcome to /diy/, a place to:

Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.

Please keep in mind:
- This is a SFW board. No fleshlights or other sex toys.
- No weapons. That goes to /k/ - Weapons. The workmanship and techniques involved in creating objects which could be used as weapons or the portion of a weapons project that involves them (e.g., forging steel for a blade, machining for gunsmithing, what epoxy can I use to fix my bow) may be discussed in /diy/, but discussing weapon-specific techniques/designs or the actual use of weapons is disallowed. Things such as fixed blade knives or axes are considered tools, things such as swords, guns or explosives are considered weapons.
- No drugs or drug paraphernalia (See Global Rule 1). If you want to discuss something that could involve such things (e.g., carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.

Some friendly suggestions for posting:
- First ask Google, then ask /diy/. Your question will probably be better received if you do so.
- List available resources (tools, materials, budget, time, etc.)
- Try to use pictures and explain the goal, if possible
- Be patient, this is a slow board; your thread will be around for days.
- Share your results! /diy/ loves to see problems solved and projects completed!

I have a 6 m2 room (64.6 square foot) that I would like to humidify to about 80% or more relative humidity for the purposes of mushroom cultivation. The thing is, I need to be able to get the humidity back to 80% relatively quickly after replacing all the air in the room to remove the CO2.

I looked around and my options seem to be:
>ultrasonic fogger which is around 100 € and has high output but I've read that these also break frequently
>water atomizer system which needs some kind of high water pressure to force water through a fog nozzle which seems expensive and the nozzles will probably clog without distilled water
>small commercial humidifier. the smart ones probably wont allow 80% humidity, and at the same price I could get the ultrasonic fogger unit which has massively more output
>diy steam humidifier which is basically just heating water to create steam, which would be extremely expensive due to my electricity cost so it's out of question
>diy evaporative humidifier, which is a fan + wet cloth strips
I'll be honest, none of these solutions are appealing. Making a diy evaporative humidifier contraption would be ok, but I do not believe the room will reach 80% relative humidity with it or it may take too long unless I make a huge one.

Is there a holy grail solution I've missed?

Marthatek grow tent/enclosure.
>>
>>2087937
Yeah man this is pretty much great. Might consider getting some high end compost.
>>
>>2087937
This uses an ultrasonic fogger from what I've seen. I want to use the entire 6 m2 to be usable so I'm going to paint the walls, doors and whatnot with some silicone paint and the floor with some anti-slip sort of waterproof paint. Having a grow tent in there would be redundant, as the room itself will be waterproof.

I can't find anything on diy evaporative humidifiers and how well they work. No one knows how well they work? can I get to 80% relative humidity fast enough if the fan + cloth strips are big enough?

AFAIU, solar water heating is one of the most energy efficient, cleaner ways to store solar energy, as long as the sun shines above the collector (even in cloudy days).
Also, hot water could be used for home heating. And if you attach peltier cells or (maybe, I don't know) a sterling enging, you could also use it to generate electricity.
I want to build my own integrated solar water heating+storage system, any pointers on building DIY solar water heaters?

I've been planning on doing some experimentation with a variant of solar power generation based on what is effectively an air conditioner being run in reverse. That is to say, a closed-cycle Rankine engine being run on refrigerant gas instead of water.

There are two significant problems:

The first is that, being a mechanical device, some maintenance more complicated than "spray it down with a hose and squeegee" will be required.

The second, more significant issue, is the fact that maximum efficiency of a heat engine is dictated by the difference in absolute temperature between the hot and cold sources. There is not, typically, a very great difference between ambient temperatures and those generated by these types of solar heaters. This can be mostly overcome by using concentrated solar collectors, but these are generally much more complicated to build than simple flat panels with tubes glued onto them.

For day-to-day heating, yeah, collectors like this work great. But getting any kind of significant power generation out of them is a non-starter.
>>
>>2088329
Could you use concentrated photovoltaic with a big parabolic dish focusing light a tiny ball/cube of PV cells, or is that not worth it compared to just paneling the rooftops?
>>
>>2088393

Concentrated PV is a thing, but one of the major caveats is the radically increased heat the cells experience. They usually have to be water cooled. Plus, the cost of lenses or reflectors large enough to make it worthwhile tend to be significantly more expensive than an equivalent amount of regular PV panel. At least, in small quantities, anyway.

As a bonus, the performance of the optics is more sensitive to dirt, necessitating more frequent cleaning.
>>
>>2088498
>They usually have to be water cooled.
could both PV and water heating be mixed in small residential setups?

What's a good price for the ender 3 v2 (shipped from yurop, though that doesn't seem to affect the price negatively)?
I've had it in my cart on ali for $208 shipped but the price went up again. Best deal I see now is $258 with 2kg of PLA which seems ok as well if the filament isn't garbage.
The multi item listings and coupons make the price trackers unusable..

I have a mamba f722s (the black one with wifi), a foxeer camera and a rush tank plus

my question is, what do I do with the OSD pin on the camera?
the camera has a port for a OSD and GND cable and it shipped with a separate PCB with 5 buttons on it.
can I hook the OSD pin up with the flight controller and maybe even get to control it with the FPV goggles I have?
do I have to set it once before flight and be done with it?
or how does this whole thing work? How do I tell the flight controller to add info to the video stream?
I can't seem to find a proper guide on how this is done.
>>
>>2088416
I don't think it's designed, it's just poor implementation. I have a USB C breakout dongle (has USB A, HDMI, SD, etc.) which complains about not having enough power unless I connect it one specific way round. I also have a USB C to micro USB cable which is super handy for connecting to flight controllers when I'm out flying, but that also only works in one orientation (though that is maybe more understandable because it's going to micro USB rather than another USB C device?).

>>2088489
The 'OSD' connector on the camera is essentially a confusing holdover from a time when flight controllers didn't have built-in OSD support.

In the vast majority of setups these days you want the camera's built-in OSD completely disabled, because you will instead be using the flight controller's far more powerful OSD. The camera probably came with it already disabled, but if not you will have to connect that 5-button board to disable it, then you can disconnect the board & never connect it ever again.

The only situation that you would actually want to use the cameras built-in OSD is if you don't have a flight controller (eg a simple fixed wing model) but still want to have your name & maybe a timer in the video. Some of them also support reading a single voltage, so you can see how the battery is doing in a model with no flight controller to measure it.
>>
>>2088495
ah, that makes sense.
the camera came with the battery indicator enabled, but it's a bit useless. I'll hook up the board once and disable it.
I had to enable the smart audio pin in betaflight (for me it was uart3) for the vtx to show up. now it seems to work.
thanks for clearing things up.

roofing is a true nightmare, I used to paint house exteriors and what a nightmare looking back on the work we'd do from rooftops. by Grace I'm here now.

Anyone build guitars? I'm trying to get into by putting together a SSO (strat shaped object) with some decent items. Nice maple neck, the body is poplar I think because it feels light, but it's suprisingly loud. I'm in the camp that it's all pickups with electrics anyway. tl;dr im using good electronics, tuners, bridge, etc
But I'm having a serious problem with intonation on this one. I measured tits perfect from the nut to the saddle 25-1/2" (12.75" from apex of 12th too) and the fucking strings will not intonate at any saddle position or action height. I even plugged the holes and moved the bridge once entirely to retry, still won't intonate. Not sure what the problem is.

toilet drain related question

Planning my bathroom remodel and I am confused about terminology. I see 4 inch pipes in the basement so supposedly the toilet can be 10 feet from the "stack". but the toilets on the second floor currently are like 25 feet away from the main vertical stack pipe that goes to sewer. There are really long horizontal runs in the basement. What am I not understanding about this? I'm trying to move a toilet closer to that vertical main stack pipe and I just don't understand how the plumbing would go or what's possible

Two plans

1. thorny hedge local to your area. If you make it look somewhat natural "local teens" will think it's just some natural growth and won't fuck with it because who would want to? You get the security and privacy of a soild fence covered in barbed wire and the obscurity of your whole property not looking like anything other than dense thicket.

2. 4 ft of stone with 6 ft of wrought iron on top. Sometimes ostentatious shows of wealth provide their own degree of social dissuasion. People might fuck with a chain link fence, but a fence that fancy probably has other security behind it.
