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!

So my neighbors sold their house, and an old lady with her probably 45 year old cave man looking neet son moved in next door.
Today seems to be their first day to actually live in the house, and their dog is in the back yard just fucking blasting.
I went to meet them and say hi and mentioned the dog in passing, and they just kind of said hehe yeah he likes to bark.
I want to stop this shit right now, hopefully without getting the cops involved.
My first idea is maybe a loud speaker pointing at their house connected to a raspberry pi with a microphone that blasts dog barks loud as fuck pointed at their House every time the rpi detects a dog bark.
Kind of like a jeet shaker but more advanced.
Btw I'm a cripple in a wheelchair, and not going to be able to do anything crazy, so I have to either do this passive aggressive as fuck or something...
anyone have any ideas?

Go to city animal control. They'll give you a form to fill out about animal noise. Dates/times/durations. Fill it all in. I did this 20+ years ago with a big obnoxious barking dog next door. Within about 2 days the problem was fixed. I don't know what they threatened the neighbor with, but it was stone cold fixed forever.
>>
>>2997884
Yeah for retards I killed 3 of my neighbors dogs with meat and poison. Nobody was any the wiser. It's quiet now ¯\_(ツ)_/¯

One room in my house gets hot in the evening. That tricks the AC into blowing the rest of the house into a freezer. I want to figure out how to get the room colder. I've just put up blackout curtains (the sun hits that room in the evening), so we'll see soon what effect that has. How to escalate from here?

My god none of you have any contracting experience! I'm so glad I saw this post, I mean offence, you are all kinda retarded.

So go in the basement, there should be vent controls on the pipes. Most homes especially older ones have that. Usually you just turn the vent controls from winter to summer. Like pic related. Or in a more modern home you close and open vents to redistribute the air flow to make sure some rooms get more air than others, look up a guide on how to balance airflow. Its probably set to winter, that's why you are roasting.
>>
>>3004364
I appreciate the info. This is an old, 1959 house in Texas. I don't know where all the vent stuff is, but I think it's in the roof. So I'll go up there sometime and see if I can find anything like what you mention. Anyway, the grilles in each room don't have the ability to open/close. So possibly I'll need to buy a new grille that I can close.
>>
>>3004366
Yeah I'm from Chicago and we have different build standards than you. A nigger rigging way to fix it is to block the outflow from nearby vents to see if it increases the flow into your room. Once you figure out what increases flow replace that out vent with one that can close and close it 90 percent. Basically you can make it so some rooms that stay too cold get less air and your room gets more. Think of it as balancing the air flow. If you can't figure it out I'll pop back in this thread to help you out.

If you don’t mind the higher quiescent current and have some way to shut them off when you lose power it’s probably feasible. It would be better if you put 3.7V zener diodes in series with each resistor, so they conduct much more at higher voltages.

But I would want to use a constant current 12V source or otherwise have a way of limiting current, a normal 12V supply will try to push a bunch of amps into an 11V battery buffer.

The wire of shame.
Thanks to the anon who recommended fine gauge kynar wire though, it seems to work well for these purposes.
You can see what happened, I accidentally deleted the GND in the schematic so the layout passed all the DRC checks despite it being FUCKED UP. I'm still mad as hell but it's not worth ordering a whole new set of boards just to fix this.

I used to work in IT for over 24 years. one job I had for 12 years I got so much computers, monitors, and any random computer equipment for free that it filled my home shop.

unlike you niggers I never stole any of it. I just offered to dispose of it for clients. my employer would give me truck loads of stuff. for a while I had so much I was scrapping loads of it.

we would upgrade an office with all new equipment and then they would just give us the old stuff. I ended up recycling, selling, and donating scads of equipment.

I currently have 6 UPS's because it was cheaper to swap them out than replace the batteries.

I have parted out dozens of old APC UPS's for DIY stuff. The transformers in the 12 volt ones make great 21v power supplies for powering cordless tools.

at one time I had over 50 LCD monitors we got from a law firm.

I had a palette of POS credit card terminals I sold to some company who refurbishes them.

pic related is an entire office worth of old phone and network cable that the network guy was too lazy to recycle. it filled a mini van half full. we got $300 and would have gotten more if we took the time to sort it.

I worked as an aircraft mechanic for 7 years. as long as you did not put something in your lunch box (the only thing security checked when you left for the day) you could sneak all sorts of stuff out of the building:
spray paint hidden in the sleeves of my winter coat.
aluminum tape
teflon tape
all sorts of screws, blind fasteners, pop rivets, nuts, and bolts which were in bins that you took what you needed to work on the planes.
I kept all sorts of extra parts and pieces in my tool box, and when I left they never looked inside it.
they had these dispensers of razor blades which had like 100 blades in each. I took 2 of them.
this was 32 years ago. I am still using nuts and bolts from then. I'm down to my last 20 razor blades. I still have rolls of different tapes. spools of safety wire. anti seize compound. grease. Adhesive sanding pads, cutoff wheels and all sorts of stuff I can't think of at the moment.

ESP also has ETH phy, so you might want to consider using that as well.
I’d use it, just because I don’t know much about CAN but use ETH all the time.
>>
>>3004208
Fair enough. ETH phy requires isolation transformer and connector hardware, but even then it's probably cheaper than CAN transceivers, and no less robust in an automotive environment. Plus all the connectors and cables are standardised. The main upside to CAN is that it's a bus, you can have multiple devices all on the same wires without worrying about packet collisions or needing proper routing. Maybe it's better for precision timing too.
