install a second airpump

>>1135447
If i i used an identical airpump i d be wasting energy by aerating more then necessary.
If i used a weaker pump it couldnt compensate the fail of the main pump.

You should be checking your aquaponic system daily. You'll find out soon enough if a air pump is out.

Alternatively, if you don't check it every day then at least check it every other day or so. The fish will be find for a short stint of time. If you're not checking you system for a longer period of time than that then sell all your shit because you can't manage one properly.

I sprayed my house with shit loads of poison last summer and fall and they haven't been back. Yet.

>>1135323
What kinda poison? It seems all the store bought ones are not strong enough, An I don't own a farm so I can't get the agricultural poisons the farm supply place sells

>>1135324
Ortho home defence I think.

>>1134835
Kinda? Pic related putts it a little under 3,000 watts brushed. It wont be very efficient, but if you are going for a bidget build and dont need much range i'd use 4 deep cycle (i think blue top) optimas or if u want a speed boost at the cost of longevity and distance go yellow top.

Problem is lead is inefficient and heavy. And 12v as apposed to 6v is worse but using 8 trojen t-105 would make that bike weigh a ton. I'd guess if you are going no more than 20 miles on the reg then 4 yellow tops would under power it at 24v x 2 banks and u should get descent speed. Sorry. It depends a lot on every other aspect of your build.

For reference my fat ass built a bargain steel frame mountain bike with 4 12ah sla's and my 289 pound body. I could average 25 mph for severa miles with no pedling. It was 48v 1,000 watt. You have 3,000 watt at that voltage but also more weight.

Thank you for a reply, I would be more focused on torque and top speed rather than range. What do you think about this one? Not sure how much it weighs but surely its heavier than other one

First learn C
It'll give you a good foundation for other languages.
You can use it for microcontrollers too, which can be fun.
Recommend The C Programming Language 2nd Edition

For android, the next step is java.
Once you learn that, get android studio.

Not sure about windows phones, I think C++ or C#

Apple, I have no idea

/r/learnprogramming

^gathers all of the best resources online on the topic

this is more on-topic for /g/ btw, and they also have some lesser info on this in their sticky

Senior game developer here, the shortes path would be to learn C and get the fundamentals of programming right then you could learn Unity game engine, its free and you can deploy to a couple dozen system including all mobiles devices

absolute shite

Aren't they basically handheld injection molders?

I mean could you combine them with paperfraft and make figurines of Video Game stuff easily?

they are shit as "3d printers" otherwise.

>>1133166
They're nothing like injection molders.

It just a poorly made, hard to use, hot glue gun shaped like a pen.

Fill with gas that is lighter than air. Attach a motor with a propeller to it. Record first flight and have friend post it on the internet after you die.

>I have a design
You do? Then fucking build it.

Otherwise what you have is not a design

I'm disturbed by your lack of confidence in OP. What could possibly go wrong.

Finer and finer grades of sandpaper, up to about 2000 grit, then polish with a buff and some plastic buffing compound.

But there is a good chance this will end up looking worse than the scratch, as you'll take off the anti-reflection coating in the area that you are polishing.

So you either need to do it to the whole screen, or, see if the top layer of the screen is removable and replace it with plastic/polycarbonate sheet.

Magic Eraser.

>>1132758
This. You'd need to treat the entire screen surface. LCD's are not perfectly glossy*, which is what you'll get once you have done your final polish on the affected area. You'd need to then polish the entire surface to match the repaired area.

*with good reason, it's terrible for viewability in all but the darkest rooms

The furnace shouldn't be on without the blower :/

>The furnace shouldn't be on without the blower :/

seriously, why do people like you post here?

>>1132400
For my personal comedic relief.

>>1131337
very. you just need a fuckload of time and a strong back.

i've actually already planned and estimated something like this in terms of the construction techniques and tools needed. its pretty cheap per square foot of wall in terms of material cost. the land cost will be the biggest purchase, even if its el cheapo land inna woods.

With enough money it is entirely feasible. Just save up a few hundred thousands dollars and you will be all set.

I dont think you need to torque a rifle scope, just hand tighten it well

>>1124410
Most of that sort of stuff that goes down to 1.5ft-lb's is specialist and unlikely to turn up for cheap + accurate readings and it really is a tiny amount of pressure really.
What I usually do is tighten the bolt so its in, not able to move back-forth and then maybe about a 3/12ths of a turn, so if you imagine a clock face, start at 12 and turn to about 2-3

>>1124423
3/12ths

Clock reference.

CAD software simply increases productivity, it doesn't make you a designer. If you can't do it by pen and paper then you won't be able to do it in the software either.

Solidworks

>>1135956
I don't want to be a designer, I just enjoy seeking out anything I don't know and make it known.

CAD isn't a place for creative design. It just translates an already established idea into a digital format.

I do lots of 2D architectural design work for my company as well as graphical side work and have always started out or drafted out plans with pencil and paper first.

For stuff with actual measurements, I'll simply copy the work over to AutoCAD. For artsy stuff, I'll scan my work and trace it over in Illustrator.

>>1135665
So long as the "cage" you use is well grounded and the metal is thick enough for skin effect, it will work. Solid metal is always better than screen or mesh. Foil isn't recommended since it is usually too thin. Hole sizes for screen and mesh matter for blocking specific ranges. That's why solid metal is better since it blocks everything. But, it needs to be grounded or it may not work properly.

No, a cave will not work 100%. Though, that really depends on how deep it is and the make up of the soil.

>>1135665
/sci/ would be better.

But speaking in /diy/ lingo, basically you want to cover something in a metal container without opening, tin foil is basic tier protection, metal cabinet or ammo boxes better, fridges or cars or metal safe are all (imperfect) faraday cages and will give some protection.

A cave deals with mechanical damage and has little meaning in emp protection, you will still need a faraday cage inside the cave.

Wrapping something in multiple layers of tinfoil, wrap in plastic bag, put inside a metal box, put inside a file cabinet, put inside a container, will give you more than enough protection. If some nuke goes off near you, you have a lot more and bigger problems than the emp.

Basically the thicker and the more insulated layers the better.

Solar storm will probably create even more problem than a nuke, but also less probable to happen. If you are venturing that far, you might need to deal with flooding or earthquake first to survive seeing a solar event.

Anyone have the current bingo card for this kid?

>>1135514
So instead of having a small engine thread, you want to stop all discussion for your bingo meme?
Its not a headphone thread

>>1135507
find the service manual ( not the owners manual, but you should have that too)

it will have teardown/rebuild procedures, measurements and tolerances, etc.

>>1134223
>>Anyone here have a recommended brand of pressure gauge? Winters, Wika, ect.

For degassing silicone, it doesn't even matter. Really, you don't need a pressure gauge in the first place. You'll be able to judge progress by how much it's bubbling and how big the bubbles are.

>>Should I purchase a Brass Mini Ball Valve, or a plastic alternative?

Doesn't matter, long as it's airtight. FWIW, my hardware is all brass, if for no other reason than that's what I had on hand.

>>What thickness should the Polycarbonate or Acrylic lid be?

For a 10" lid, 3/4 is fine.


Also my preference is to just cut a ring out of a sheet of rubber to use as the gasket. Easier.

>Also my preference is to just cut a ring out of a sheet of rubber to use as the gasket. Easier.
I was planning on utilizing my remaining Platinum-Silicone as a gasket. could it work?

>>1134241
>For the Polycarbonate or Acrylic?

Either.

>I was planning on utilizing my remaining Platinum-Silicone as a gasket. could it work?

No reason it shouldn't, assuming you're not intending for it to just be a loose part, and not actually adhere to the lid.
