How much effort should it be to remud a room?

I've been working since Friday (with a significant break yesterday) and I'm nearing the point where I'm ready to paint. I've used 70lbs of joint compound already and I'm feeling like this is too much as I haven't even done the ceiling yet. How badly did I screw up?

On a side topic, at what point do you say the job is too big for you and hire someone. I'm starting to doubt my ability here.

I am working on a idea for some remote controlled equipment via phone

Initially I thought about data over sms but then found DTMF solutions as pictured

I am looking to do some kind of remote home automation like adjusting thermostat or opening garage door via text or call

I also located a carrier called Truphone that provides global phone coverage through their own network and allows free incoming calls inside the US and UK I verified with their rep at the call center that you pay upfront for the sim card ($20) and some prepaid minutes (the minimum) and...

Text messages are cheaper than voice calls, and you'd need to be making voice calls to transmit DTMF.

Cell phones don't use DTMF. If you hit a button while talking the other end doesn't hear DTMF like with land line phones. You'll have to create an app or external device that plays DTMF into the cell phone voice connection.

Voice calls through a cell network are digitized and compressed. Your DTMF could look like background noise and get filtered out.

Does it have to have a phone on the other end? You could get a raspberry pi and control stuff over SSH from yhe internet. Instead of using a cellphone, you might use a GSM module, which is a cellphone in a handy hackable format.

It might be best to use a GSM module and send it SMS messages to control what you want to do. For best results use encrypted text messages

Sadly most projects involving tubes are pricey. The only cheap way is to find a very small project requiring minimal parts, or impractically scavenge parts from old circuit boards.

The most expensive part of tube amps is usually the transformers. Making those yourself is cheaper than buying them but it is a pain in the butt...
>>
>>1018577
your 6sn7 is a medium gain dual triode which would be fine for a line level first stage of an audio amp. You would still need some beam power tubes for the output stage. as for the transformers edcor sells very reasonably priced output transformers.
https://www.edcorusa.com/xse10-50-8k
of course you have to match the output tubes with the impedance of the transformer.

You will need a power transformer which edcor sells those as well. You would need a plate voltage of less than 450v using a modern rectifier...

Is someone going to be living or dying based on this? If that's the case, seriously, just buy whatever is needed.

If you're just fucking around, the 12V battery you posted is a sealed lead-acid battery, commonly referred to as an AGM. They are heavy but reliable and hold a good amount of power for their volume. If you know the ampere-hour requirements, you can pretty easily match up a 12V AGM battery. They make them in all sorts of sizes/capicities.

NiMH would not be that great, they are actually a pretty crappy battery. Low charge holding and they deplete...

Hey /diy/, I'm trying to figure out if it's a bad idea for me to build/use a homemade rotary tool like in pic related, safety wise. I'm planning on using it to cut mdf boards, and pvc piping, nothing particularly strong. Assuming that I use gloves, safety glasses, do you think this is a bad idea, or am I overthinking this?

That on e pictured is very low power and low RPM. It would be quite safe to build and use. Operation would be slow. If you decide to use an AC/DC wall unit, make sure it has at least a 2 amp rating. When a motor stalls it eats up a massive amount of power (sometimes peaking at 90+amps for a normal battery-powered drill for instance). The motor used in that one most likely won't exceed 2-3 amps when stalled.

However, a high speed, high power unit using a blender motor requires more experience and skill to...

The plan was to use about 5-7V worth of NiMH batteries, which push out about 3A, for the power source.

Going to use wall plugs to connect the connect the motor to the drill bit.

Think this will be strong enough to handle small amounts of MDF?

hey /diy/, turns out my housemates are nosey fucks and like to go through my stuff while i'm not home. my door can't even be locked from outside.
thing is, my door handle seems to be fatter than any handle i've seen that has a proper lock, though admittedly i haven't exhausted my search quite yet.
the question is, is it possible to change the handle to one with a proper lock without having to saw the wood or leave open gaps at the sides? how likely is it to find one with the same size?

I recently moved in to a house and the previous owner was a fairly heavy smoker.

Today I had the air ducts cleaned and sanitized, registers changed, and carpet professionally cleaned. I've heard good things about air purifiers.

Are there any proven ways besides repainting the walls and tearing out the carpet?

Thanks

from my experience air purifiers don't really get rid of the smell, although give it a shot, they can be expensive but even if it doesn't work you will just end up with cleaner air and feels good to breath

After bushfires, residents use ozone generators.Perhaps you can hire a professional unit from somewhere. I don't know how they work or even if they work, maybe google it

>>1017180
This, an air purifier only removes the smell that's reaching the air.

Ozone and repainting/carpeting is probably the best option.
