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!

>>1480877
Thanks. My ruler says 2mm and the other end looks to be 1.25mm. Think I'd have an easier time splicing two pre-terminated cables instead of attaching a connector myself?

I have a long narrow room setup like this (albeit shorter, ~8ft tall), where my bed is up against an exterior wall with a window. In the winter, this wall is extremely cold, to the point that the baseboard heating doesn't compensate. How would I best insulate this wall? I'm thinking of hanging up a tarp a few inches from the wall and taping it all the way around - does this sound right? Or can I just buy foam insulation board and prop it against the wall? I used a window wrap kit last winter, didn't do much. Thanks, all help is appreciated
>>
>>1480244
the cold is coming from the window, not the wall. Measure your window then go to Wal Mart and buy a kit with double sided tape and shrink wrap and borrow your girlfriends/mothers hair dryer and follow the directions.

If your wall is still to cold then either call someon who does insulation (or tell your landlord) and have some blown insulation installed.

As said above with the shrink wrap, but guessing old building. Some of the cold though may be coming from the floor even with baseboard heating depending on how lazy people were.
You might have to go space heater in a corner. I suggest a tower model one with a temp on/off so when it gets to 60 it turns on till 70 then turns off. Look into spring/fall camping gear for the bed. Just unzip completely open and use as bedding. You will be sweating in no time as they are built better and are far cheaper. Normal sweat pants and long sleeve shirt are no joke, you can survive a lot in these.

I would skip the window "kit" I have old windows in my apt and this year I got 4 mil plastic from menards. It was way cheaper and thicker than those window kits. Plastic the window then hang some big curtains. Also you could caulk around the outside of the window. And if all that doesn't help I would make a foam insulation headboard.

>>1480244
Pull the bed away from the wall as far as you can. Maybe look at electric mattress pads.

Use thinner wire. 220V is 220 watts per amp, so if they're e.g. 44W you only need 0.2A. 230V mains flex is normally rated for at least 3A, and solid cable for 15A or 30A.

if you designed the board you could just send off the gerbers. most places will charge based on the size of the smallest square that fully encompasses your design. just draw the shape you want on the board outline layer and (for safety's sake) put some "CUT OUT" text in the middle of your circles
if you want someone else to make the layout, you could hire some pajeet off one of those freelancer sites. pajeet will send you gerber files which you would review using a gerber viewer and then send to your choice of board house
if you want someone to stuff and solder the board for you professionally, that's another $100 or more. maybe you can find some kid in the local university's EE program to do it for you and save a few bux

>>1480885
you could buy one of those 200kHz STM32-based scopes now for like $30. you could also look around for those good old 20MHz dual trace scopes on the order of $100, maybe less by now. a logic analyzer might serve you better for the CompE work

That's the one I have. I had to do some work after I bought it. They forgot to put insulation in the master bathroom wall. The toilet was rocking back and fourth, it was sitting high off the floor on the pipe. I had to change the faucet in the master bath it was leaking in the wall. They ceiling vent wasn't wired into anything. Both doors leak on it. I had to build a front and back porch with rooves to keep the rain from coming in. I installed mini split heat pumps in it. It is very efficient aftewr all is said and done. I don't think I should have had to do so much work on it. They drop dramatically in value. Good luck trying to resale it for anywhere close to what you got it for. I think they go $10,000 as soon as they leave the sale lot. If you go to get one do check these types of things.

It's not considered theft, just picking up litter.

Absolutely! Check out what inputs the motor controller accepts. Might just be a simple PWM input.

They tend to do well in major metropolitan and Universities. Fuckin' Lime and Bird took over the downtown area over night, then were banned by the city, and then quickly re-instated after the city found a way to charge the company to operate in the town.

dont matter. I think in the immediate term, these companies are up in the air, they're a nuisance to the city, and they can get the scooters for so cheap in a bulk deal, so it's probably cheaper for them to take the hit until they can get more robust anti-theft tech in a scooter (if they can)

cops just probably aren't gonna do shit about this until the lime people are either a) paying their salary via taxes or b) scooter theft becomes grand theft auto

Look at Joshua Bardwells youtube channel.

He actually just posted this like 15 video series on every little step you could possibly need help with building. Mind you itll be easier if you use the same components as he did which is a $200+ build. But in the long run youll enjoy it more than one of those $100 ones.

The big issue is that the pitch bar in the mission planner has to move in the OPPOSITE direction to your stick to be correct, which is dumb as all fuck. Unless you're reading the wiki really carefully, you'll look at the bars, see that they all move the same way that your sticks do & presume that everything's fine when in reality it's not.

You can test it (& I would recommend you do!) by arming the quad without any props attached & checking which motors actually speed up/slow down as you move your pitch stick.

Picrelated should be a giant red fucking flashing box on the wiki.
>>
>>1481071
So moving pitch forward should move the bar backwards and visa versa?

Makes you wonder why they ever thought that was a good idea. It had to have been done for jokes.
>>
>>1481093
>So moving pitch forward should move the bar backwards and visa versa?

At least in Mission Planner, yes.

>It had to have been done for jokes.

The only legitimate explanation I can think of is that a decade ago when originally writing the code whatever radio one of the devs was using did it that way & they've refused to change it since, even when literally everything is now the opposite way round & people are literally totalling newly built quads because of it.
>>
>>1481095
I recall old video games used to invert controls in a similar way for vehicles, maybe they were shooting for that.

That copper is blazed not soldered, the temps of brazing take a lot of strength out of the pipe because it takes all the temper out. Generally only medical gas line and refrigerant lines are brazed.

Think about that statement for a minute. Do you really think they stay connected by a copper line throughout the entire installation?

You realize all the refrigerant is inside the condenser, right? Once you hook it up you leave the condenser isolated and vacuum check the lineset and evaporator. All good? Crack the valves and let the refrigerant into the lineset

Secret accidents/mishaps nobody knows about

Back in the days when the first 1GB IDE drives became available, a customer bought about 20 for his servers. I somehow managed to topple over the service cart with them and sent them onto the floor.
Of course I told nobody about that very expensive accident and added them to the servers.

Within a year, roughly 80% of the drives failed.

We agreed with the customers that 1GB per drive was just too much to be handled for the manufacturer. Drives were from IBM, so nobody questioned that.
