Hey /diy/, got a little pet project for you guys.

I work for a rather large municipality and a big part of my job is to take out the trash.
Sounds simple, right?
Put in a trash bag, next day, pull it and replace the bag.

Well, our cans come equipped with bolted on lids that only open partially.
This is to keep the seagulls out.
They eat the garbage and shit in the water, lowering the water quality and littering the beach.
Bags don't stay in, they sink right to the bottom.

The result is: double the manpower (2 people need to lift and flip a heavy can and dump into a bag) , double the money spent on bags (tax $$$) and back injuries/hernias.
I dump hundreds of these things a day on top of the stuff I already have to do.
My municipality wont replace the cans, we're talking 3000 plus cans that are compliant and they're paid to have because of the advertisements on them.

If I could find a way to secure the bags in the cans where they wont fall to the bottom and I can simply rip the bag out, we could save tons of money, manpower and injuries just on this one simple fix.
So what do you guys suggest?
(btw, if we rip them off, they're replaced and we get gouged for like $90 a lid)

>TL;DR How can I keep the trashbags from falling down in these trashcans?

I am trying to design a circuit that will allow an appliance to stay connected to wall power in the US only as long as a LASER shines onto a photosensitive element on the circuit, using a solid-state relay.
The control circuit itself is wall-powered through a voltage regulator.

The plan is to eventually get the control circuit printed onto a PCB and the whole thing (with the relay and regulator) in a project box with the LASER diode, switches, photosensitive-resistor, and connections to wall cable and appliance attached.
I dunno much about circuit design so I came to /diy for feedback about effectiveness and safety of my design.
Any feedback would be appreciated.

Thanks, /diy/

There are some of us on /out/ and /r9k/ that would like to build a men only compound.
The basic idea would be tiny houses spread out in the woods with a main buildings housing shower/bath facilities as well as kitchen and workspaces like woodshops , metal working shops , auto mechanic areas and whatnot.
There is money set aside for the project but the benefactor will not start releasing funds until a critical mass of problem solvers start taking the initiative to start fleshing the ideas out further.
Areas discussed so far for buying the land are
Florida
Maine
Southern Colorado / Northern NM
Idaho and Kentucky.
We have a few home builders and a plumber and electrician.
We need an architect pretty bad as well as guys who can set up internet infrastructure.
Anyone interested?

Need to convert a single pole switch to a 3-way. Any resource on this? Idiots who built my house put a switch at the top of the basement stairs but not the bottom.

thninling about buying a camper like the one pictured. called an "Aliner". it needs a new floor - aparently the water tank leaked and rotted out the floor (see next pic). I'm good at fixing thing, have ton of tools etc. wondering how hard to replace a floor in one of these campers. I wouldn't use the chipboard that they used when new. probably some 3/4" marine ply? then do a nice wood look laminated flooring over that. guessing I'll have to take out the cabinets and everything too. I'll take out and leave out the water tank - don't need that.

I work in starts and fits, and cleaning interrupts my... flow. These forthcoming pics are the result of breakthroughs, self challenging math shit, NW SAD inducing weather, limited resources, addiction, doggo love...
I can clean up in like two hours, if I ever have company again.
Anyone else work this way? I know a clean workspace is best, but I got shit to do, and if I clean, I'm not focusing on my shit to do.
Post 'em. Don't be ashamed.

Never welded before but always thought it'd be cool to learn.

Will I get far with this or grow out of it too quickly? It's about 500$

Hey, im making an engagement ring to my fiancée.
I used bog oak, Im almost done, I abraded the wood with very fine-grain sandpaper as finishing touch, but when I wiped it with a slightly wet cloth to get rid of the dust, thin fiber started to come up.
Is there some wood treatment material I can use to prevent it? is wax good for that?
I'm worried that, when shes going to wear it for longer time, slowly it will become ugly. The ring, not my fiancée.

the picture is only illustration because i fucking have to

Hey guys, I have an older compressor that I don't use that much except for filling tires and blowing out my pc. Last time I used it, it filled itself up, but when I went to use it, it just spurted out some air then was done. It didn't turn back on, but I had to wait about 30s before I could blow any real amount of air, then it did the same thing. Quick burst of air, then just barely anything. I went to drain the air tank, and it was completely full of air just like usual. Does anyone have any idea what might be going on?

What garden partition has the best blend of:
>privacy
>low maintenance
>durability

At the moment I have a beech hedge (pic related), which is nice in summer and only has to be trimmed once a year, but is virtually see-through during winter.

Anything goes: other types of hedges, wooden walls, etc.
Just nothing that I have to trim two-three times a year or falls apart after a few years.

im installing an amp in my car and im trying to hook up a direct line in to my phone to bypass the radio (though a dual channel pot for volume control). i would expect the phone's 3.5mm jack to be in stereo tip ring sleeve, however when i hook it up as such (left side of the pic) i get like a conflicting signal and it cuts out all of the top end and is very quiet. but when i hook it up like on the right side of the pic, i get full range and full volume. also i dont need to hook up each channel to both the + and -, i can do just one or the other and it sounds exactly the same. also another weird thing is that if i just hook up one channel or the ground, it will quietly play like its picking up the signal as rf over the air and i can touch any of the other wires and it will play the signal at almost full volume through my body, even if im not touching the phone or car body.

so im not exactly sure why the 3.5mm isnt outputting the way i think i should and why i need to wire it the way that i do to make it work. do phones have a different kind of 3.5mm pinout?
also im not sure how the signal is able to jump wirelessly simply through a male to male jack and through me.

I'm making a dozen of IOT devices that sends me real time temperature and humidity variables through the internet, and will send me an instant alert if there is any sudden change. These will be battery powered and as portable as possible as I will keep these all over my city. If anyone wants to know I'm using ESP8266 with DHT11 and Dweet.io as the API. With around 10-20mAh as it's power consumption, I can easily power it for a month or two with some AA batteries.
The challenge here is providing the ESP with an internet access. I wish to make these devices self sufficient and have it's own internet. With some research I came across this 4g WiFi dongle of a perfect portable size but as there was no proper data sheet published by it's maker, I decided to buy it and test it myself. It works like a charm but sucks around 200mA on an average which is a deal breaker.
I would appreciate if anyone here can advise me a very low power and low data internet device or DIY arrangement that can fulfill the needs for the above project.

tl;dr anyone knows a lowpower internet device plz?
