So Is there anyone who know how to work a arduino?
Project Solar tracking rig for maximum sunlight using a arduino.
1. Fully automated sun tracking. 2. I must have 2 axil control. 3. Abel to hold 10 panels. 4. High winds must be taken into account and turn accordingly. 5. Low budget.
So there is my project (Personal project for own home. No power grid connection. Solar only) that im busy with. Point 2 and 3 I can do. Im studying mechanical engineering part time right now. So the rig and strength is not a problem for me to build.

Listen bro, I can't help you with this but I just want to share something I've learned through the years.
You're going for the holy grail right now. Don't. First build a platform that can be turned and skewed with a simple panel. Fine tune the shit out of that, it needs to be absolutely flawless. You'll need an Arduino, some motors and a little pit of engineering.
Once that is all done and is working like a champ, once that is done.. don't you fucking dare build a sensor that tracks the sun.. the sun follows the exact same path every... Comment too long. Click here to view the full text.
You'd have a much easier life by programming it to move according to a timer.
Sensors introduce complication and a damaged sensor can screw over your entire array. >bird shits over LDR Another complication you'd encounter is cloud chasing. Your array would get disturbed by clouds since they'd change the values of your LDRs leading to basically your array moving constantly during the day, burning away the little electricity you have. Now to solve such an issue you'd have to introduce mechanics for dealing with... Comment too long. Click here to view the full text.
Stupid question I've got one of these portable ACs in my office, and the exhaust tube goes up to the ceiling So when it's running, the tube is radiating a quite a bit of heat. I was wondering what's the best way to insulate it
>>998140 Best way to insulate an air duct is just wrap it with foam or other types of insulation, but tobehonest just wrap it with cardboard with some duct tape will help a lot since it is not a huge issue anyway
(they are used in starbucks coffee to hold a hot cup so they works)
What do with a cherry log that's 1m long and 20-30cm in diameter? Basicaly i need ideas. Google mostly gives me chairs and benches and i have no need for those. My tools are limited to chainsaw ( could be used to rip that bitch), el. plane,circular and jigsaw and a lot of hand tools. I guess i could have it planed somewhere nearby but i could go the hard route with a hand plane/scraper and a shitload of sanding. God i just love sanding. Don't you?
I want to get into gas welding. Any anons can recommend some equipment? From what I've read good low pressure regulators are important. The options for torches and tips is a little overwhelming doe. I'm mainly wanting aluminum and steel cut & weld capabilities.
>>994981 I do know about it. I have done gas, gtaw, smaw, gmaw, Flux core, etc etc welding of all kinds and gas sucks. It's good for one thing and that is cast iron and honestly tig/gtaw welding is better.
A stick and tig machine can do titanium, stainless, magnesium, aluminum, mild steels, white metals, brass, bronze, copper, etc etc.
Gas cannot do those thing. Gas is good for heating metal and cutting. It's a poor welding medium compared to any Arc welder.
I assume they are fuses? They have 30A500v rating on them.
My workshop is only 220v with 2 double outlets on the same line and 2 ceiling lights and that is all the electrical in there.
I want to move/add some more double outlets on the other side of the room and I am not too familiar with fuse breakers. Is there anything I should consider, other than opening the circuit, before beginning?
>>1007587 They are wire fuses, if you pull them out and look at the reverse side you will see two terminals with fuse wire across them, the wire thickness determines the value. You will have one for lights and the other for sockets, assuming UK that should be 6A and 13A respectfully. If you plan on using it as a workshop, would get it all replaced with a new consumer unit using rcbo's, cabling and sockets. Those old fuses are notorious for being slow to blow or having the wrong wire installed. You can find modern RCD drop... Comment too long. Click here to view the full text.
Got a Siemens A14-16 frontload washer, unfortunately the bearings broke. Now a new problem arises: how does one find the type of bearing for the machine? (I'm not at home so I can only look up the model number)
I went to a tool show recently and tried everything from impact drivers to skill saws, jigsaws routers and I can't make up my mind as I want to replenish my cordless set as its ryobi. I'm thinking makita but I'm also swerving toward Milwaukee, what do you guys think?
rather than running a conduit under a road to connect a simple rj11 cord, I am hoping to wirelessly do it, but I cant quite find something that would work exactly
I was thinking of using a hobby drone telemetry transmitter and just going pin for pin or using an rs232 transmitter and going pin for pin though for both of these I'm not too sure whether it would even work
it seems like such a simple concept, yet I am having a real pain finding something designed specifically for it that isnt an "through the power outlet" style extender

I've just given an apartment to rent a house. I want to have a Hank Hill-tier lawn, but it's currently half grass half weed. If I dump pictures of the weeds, can /diy/ help identify them and their best removal method? The lawn is in Australia.
>>1007882 A broad-spectrum broadleaf herbicide will kill almost anything with broad leafs (surprise) - you don't need to do much specialization. Won't touch crabgrass through, like in the first picture. That you need to get before it germinates, i.e. next year.
Meme answer is to just roundup the whole fucking thing, till it and resod/reseed. That's not necessarily a bad idea if it's really too far gone.
I've determined that my welder is frequently shorting out and flipping the breaker when I use it. Should I make an attempt to have it rebuilt? And if not, is there anything else I can use it for? It is a very old model, and I wouldn't mind replacing it, but I don't want to be wasteful.
There has to be a shop that repairs electronics. Or go to a hardware store and ask if they have any idea it could be worth repairing. Good to see you don't want to be wasteful :) About half the time it isn't worth repairing though. Gl
Mom has hit a rough spot again. It seems the Alcoholism and Deflated Ego has come to a point.
I've consulted her since I was a young teen but it seems it's out of my hands at this point.
I know this isn't really /DIY/ material, but how would YOU go about helping/treating YOUR Mother whilst knowing that you aren't putting her through unworthy programs or simply not letting her put herself out of misery?

I need some help guys, my garden is mostly clay and during yesterday's heavy rain completely flooded resulting in water coming up under the door and flooding my house. Is there a way to help prevent this? I was thing of using a yard stick to make deep holes in garden
>>1007656 have you actually seen this done before? Reflow oven temperature zones are static, so ramping a toaster oven doesn't really compare. You would need to invent your own oven curves since the ramp times wouldn't be similar at all.
If you are serious about doing it then thermocouple each board and use that for the feedback loop directly. You'll be able to tell when you hit thermal equilibrium to end your preheating zone. I don't know how critical the TAL is, since your oven probably wont be... Comment too long. Click here to view the full text.
>>1007729 shits all over the internet for hobby grade shit. And this is what I was talking about for reflow curve, although I'm sure temperature profile would be a more appropriate name. I was under the impression that there's one provided in the solder paste datasheet to inform what temperatures and times the paste needs.
And of course I have a thermocouple for feedback. How else would I know anything about whats going on inside?
The elements are basically hooked up to mains through a solid state relay... Comment too long. Click here to view the full text.
Hey guys, I have a few PSU's What are my options to do something useful/interesting. I've already made a bench power supply, a usb charger array, and powered a car deck and speakers to make a really dope speaker system with bluetooth. I have a few more left. Any Ideas?
>>1007320 Picture of the valve. Sounds like I might need to return this thing to Amazon and get the right one, but finding the right one is proving to be difficult because they use the same image for every fuckin' product.
Thinking about moving some books and stuff into plastic containers out in an external storage shed.
This is actually my dad's house I am sorting out. He's too old and I'm too busying trying to get myself together to actually build one like a cousin's husband did. Beautiful work he did himself, but it was expensive and time consuming.
What would you suggest for a simple shed. Thinking $500-$1500 range.
i have a few Rubbermaid Roughneck boxes outside, and not a drop of water has gotten inside in 3 years time. still, i sometimes use a dollar store tarp to make sure they dont collect water over top, and use a string to wick away any water that does. a thrift-store tent would also work if you patch any holes.
>>1006939 Bullshit. Without a seal, water will get in.
All I can tell you is that Lowes/HD sell displays for dirt cheap sometimes. If you do put those containers in a shed, buy some insulation tape from Lowe's/HD and make a seal around it before you close it up, and put some moisture absorbing shit in there. Arm and hammer, silica, whatever. I still regret leaving mine in the garage.
the plastic ones work decently, but i wouldn't put books in a shed unless i didn't care about them at all, and at that point i'd either sell them or get rid of them. . .
if you're going to do that anyways, get a solar powered vent fan to push out all the hot air that'll ruin the books over time,
go get a plastic drop cloth, and use some black silicone to hold it up no water will make it in, and get any kind of screen and use more of the black stuff to hold it in place over the vents to hell keep flying bugs out

Got this all at a garage sale for $65 Did I do good /diy/?
Never really done anything with tubes, but each box was $20 and there has to be atleast 50 in each box, and looking a couple up ranged from $5-$20ea on ebay. They had atleast 10 more boxes exactly the same, and 20 more radios of different types ranging from $25-$45. Should I go back for more tomorrow? Maybe buy in bulk and strike a deal?
Alright /diy/nosaurs! I just inherited some property and I'm looking to clean up and build something in the backyard because I'm bored, but I can't figure out what to make. I was hoping you guys could give me suggestions. I was thinking of a shaded area over what will one day be the garden, but that's all I've really got so far. (California central valley heat is brutal) Any suggestions? Preferably to do with wood since that's what I'm at least adept at, but really I'm up for anything. I was also thinking about a Japanese smoker... Comment too long. Click here to view the full text.
>>1006321 Restoring and maintaining that grass will be a bitch. Would local codes allow you to dig it up and replace it with some kind of stone or sand? You could start a trend in both style and water conservation.
