Hi /diy/, I want to mount a 150lb enclosure (with all server stuff inside) to a concrete wall.

I plan on using tapcon screws. I was told it would be good if I drill a hole through a wooden 2x4, then attach the 2x4 to the concrete. Then I can attach the enclosure to the 2x4.

What do you think ? I am worried that the 2x4 may not support the 150lbs.

I have a welder has started tripping the breaker about 30% of the time time I strike the arc. The breaker and circuit are big enough for the welder, in theory, so I assume that either the breaker or the welder are wearing out.

I would like to get an ammeter to measure how much current is being pulled by the welder when the breaker pops. Will those energy-saver gadgets from Home Depot work? Or maybe one of those clamp things that electricians have on their multimeters?

is the breaker new? i'd try putting in a new one.


'energy saver gadget' like a kill-a-watt should give you a max reading but someone will have to be watching it on amps display mode when you strike the arc ( at least on mine ) because it doesn't save that info.

- remembers peak usage (allegedly) - $15 = maybe 5% -/+ accurate tho, but, be enough for this. Whats the welder rated at, breaker can/should have a little headroom, but normal breakers (non GFCI, etc.) dont usually start wandering in their trip rating either.

a kill-a-watt type device might be destroyed, or at least damaged, if you try to use it in a case like this. a better idea is a clamp probe with a ''surge'' or ''inrush'' setting. which is not gonna be cheap, i dont think.

more info here: http://en-us.fluke.com/training/training-library/test-tools/clamp-meters/how-and-why-to-measure-inrush-current.html

what i would do personally is to use an old broken clamp meter i have, and just connect the pick-p coil to the audio card on the computer, while running a software scope.

Anyone dabble in Shortwave radios? I was thinking about picking one up, but I'm not very knowledgeable on the subject. Listening to foreign stations and number stations seems like a nice little hobby to get into. Tips or good models?

What are the general calculations for building a fence? I need to figure out how much material I need for around 60-70 feet of fencing.

>>999120
Calculate the volume of your yard, subtract that from the perimeter of the height.
>>
>>999120

Google.com
>>
>>999120
a = width of spar / (width of spar + width of gap)
b = height - bottom gap
c = length (=60-70ft?)

total length = c * a * b

is assuming NO WASTAGE

wastage is something like
height modulo timber length / timber length
multiply by wastage then add 10% for good luck

i am not an expert in eithe maths or fencing so this could be completely wrong but i tried my best.

As we’re well into the yard maintenance season, how about a yard equipment thread of stuff we either have or would like to have?

I have the pictured Ariens lawn mower, that I bought a couple years back ($700) to replace my 20+ year old Ariens mower that had given up the ghost and while I like the caster wheels, (pretty much mandatory IMO) they changed the drive system design over the years and I dislike the cut out in the deck for the drive belt on the new mower, which allows dust and clipping to blow out.

Two years or so back, when we had the Snowpocalypse winter here in Michigan, I was King Shit of the street and would snowblow the sidewalk almost all the way up and down my street, as those little pussy 2-stroke singe-stage blowers were wholly insufficient.

I'm trying to salvage 2 lcd monitors from a former store display.

I want to be able to use the screens as monitors, and I'd need them to plug into a computer easily (usb cable, microusb to usb cable, etc).

I've already taken it apart somewhat (nothing irreversible, only screws and cables) and I now have a screen with an lcd ribbon sticking out of it.

What can I do with this to make it into a monitor? I obviously need a way to power it and a method of transferring data, but I don't know where to begin. I can remove and use some modules...

Hey /diy/, I've got a 250W KEF subwoofer with a dead amp (pic related). I'm thinking of repurposing it as a subwoofer for use in my Corolla (has aftermarket radio). I thought maybe I could save some money by building my own amp from scratch. I've got plenty of free time over the summer so why the fuck not? Could be a fun project.
>many of the parts from the subwoofer's original amplifier are still functional and could be useful
>needs to run off of 12VDC power source from the car battery

Good luck. You'll need it. Guaranteed headache.
>>
Will you design the amp from scratch or use different DIY stuff from eBay?

I know quite a bit about power electronics, and generating a higher voltage from 12v with substantial wattage, is not easy! Especially because you would need more than one voltage for your control.

If I were you, I would buy a 12V boost module from eBay. Go with something physically big, they overrated power a lot, and neglect sufficient cooling..
Then find a class d amplifier module, and combine in a box. Add additional decoupling after the boost supply.
>>
>>1001913
Probably going to get kits from eBay as needed if they end up being cheaper.
What do I do about going from 12VDC to a bipolar [some voltage]DC as required for the amplifier?

I've been looking Into building a yurt and was wondering if /diy/ has any advice before I get started. Alittle background information. I live in Texas so building codes and heating aren't massive issues.
Shit I already know
1. using cedar wood for construction
2. lattice work will require a jig for proper construction
3. Double bubble insulation should be sufficient for Texas
4. The skin of the yurt is going to be very expensive and there isnt much you can do about that

Things I'd love advice on
1. The math involved in creating lattice...

These guys have alot of parts for sale and what not but even if I used found materials off Craigslist it's going to cost $2,000 bucks for their treated canvas. Cotton is great for the summer and when it's dry very breathable and cheap but it doesn't like heavy rains and mold and mildew become a problem it would require treating regularly as well as waterproofing.

So I have this Strat when you lower the action by the bridge, it goes out of tune and fixing the tuning just makes my string harder to bend. Is that normal? I already changed the string to 9s.

>>1001582
so when you lower your action and readjust your intonation, the string is more difficult to bend? That would happen if you needed to move the saddle away from the nut, making the string's active length longer, but I wouldn't have thought it would be that noticeable.
>>
>>1001582
Going out of tune sounds normal, in fact you should probably check the intonation as well. Harder to bend? Not sure about that one but instinctively I'm guessing it shouldn't change much. Have you tried /mu/?

What is: truss rod.

The issue isn't necessarily at the bridge. I've had an issue in the past with a 335 and I ended up adding tension to the truss rod to correct it.
