My country is heavily restricting sales of thermite so I thought of making my own. But I want to be able to create something purer and better quality (then that DIY shit you often see on YT).

I have money, time, lots of tools and a creative mind.

I am renting a house, and would love to be able to have a place to sit, eat, grill etc, but there's no deck or patio area, see pic related is theback door. The landlord also won't let me build a patio for some stupid reason and wants it left with the stairs just ending in the lawn.

Is there something I can throw down on the ground to make a temporary patio like surface while I live here?

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...

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...

Probably pipe insulation, if you can find it in the right diameter.

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

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.

Hello /diy/. How to build a circuit for 9 12vDC@1.2 watts with Arduino Leonardo? How it will works is that everytime a button is clicked, it would light up.

I'm currently building a Pop'n Music controller and I'm already done with the wiring. All is left to make it pretty is to lit it up.

I got this in my workshop/old maids room

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
Its hard to tell what these were used for without you tracing the wires. It might be that each of those outlets has its own fuse (protip, look into breakers).
>>
>>1007597

The outlets are on the same line as previously mentioned. Wires are surface mounted on the wall
>>
>>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...
