>client wants a raised fish pond like this

Alright. Make a structure out of wood, weatherproof it, whatever. Add a pond liner and it will hold water.


But it will be outside, so it can overflow in very rainy days. How can I add an overflow outlet to a PVC pond liner?

1) Cut a hole in it at the hight you want it to overflow at
2) Add a PVC pipe or similar as a spout to direct run off to a convenient place
3) Profit

I'm sure you could think of that yourself though, what part are you having trouble with?

You don't put the over flow through the liner, you put where the liner ends and in your case the wood starts.
>>
>>948538
From the outside (dry side), put a piece of PVC pipe against your liner so you can see the outline on the inside. Put a smaller diameter short piece of PVC pipe against the liner from the inside, so the OD of the inner piece aligns with the ID of the larger, outside piece. Hammer the the thinner piece into the thicker piece for a press fit. Cut a hole in the liner inside the pipe. Cut the short piece, paint it, use some sealant/glue. Whatever to make it pretty and durable.

Find an old book. The oldest they have. But not too old. Maybe early 90s, if it has tubes and valves instead of silicon it's too old. Unless you want to learn that stuff.

Theoretically, is it possible to make a radio transmitter with an Arduino?
Can't the current variations required to create radio waves be created by programming the Arduino appropriately? (Use the sine function and shit.)

Why tho.

You can make an FM transmitter with a hand full of caps, a linear pot, a transistor, some thick ass copper to make an inductor and some perf board.
>>
>>950704
You can. Not sure anyone has written libraries for it yet, but you could do it.

Of course, you'll still have to make an antenna, and it's going to be a very low power transmitter unless you send the output through an amp first. If you're going to need an external amp to make it worthwhile, why not just assemble the whole thing without an arduino?

Hi /diy/,
a badly beaten Asus eeePC 904HD netbook has recently got in my hands. It has ceased functioning after ~5 years of working in hands that didn't care about computers due to having some liquid (probably water) spilt on it.
However, it still seemed to boot up after being damaged (just asked to set settings in BIOS), but I disassembled it and used 90% isopropyl alcohol on it. Now it's dead. What did I do wrong? Can soaking it in IPA90% help?

90% is not 100% and maybe some liquid is still trapped underneath the bga chips
or the soak you did moved the inflicting minerals/debris to an even worse place

clean again using something "cleaner" like destiled water (this is super cheap, just ask for unscented steam iron water or acid battery water)

My mini fridge is dead. It won't make a sound. It was left off for a few months and is stone dead.

Compressor coils measure 6, 14.5, and 20 ohm with no shorts to ground.
Samsung D130c-l1z2

The ptc relay measures 9 ohm.
part no. j531 q32e

The overload protector measures a short.
part no. 265RHBYY

I have a ton of high voltage capacitors on hand. Should I attempt to rig up a hard start kit?

.... I wasn't able to get useful information testing the temperature control so I jumped across it. The compressor is running.

Pressure cutoff? Do small residential refridge even have that? I work on dishwashers, I don't know. If it isn't working it probably developed a leak over time and won't start because a pressure sensor is telling the board that there's no gas. My father in law's refridge died in a similar fashion, except I found the main board fried. Everything worked except the compressor wouldn't run.

I'm getting a good deal on this house because it used to be my parents. It's not great looking and it's from 1959.

I have questions as a first time homeowner looking to make it both more comfortable and more valuable:
What style would you say it is?
What porch/deck design would suit it best? I like craftsman style but don't know if it would be appropriate.
What paintjob do you think would work or should I just leave the brick and put some primary color trim up?
Any other ideas that leap out at you?

By style I mean this

I can't figure out which one it is I feel retarded. I just want to Google whatever style house it is so I can look at other people's homes to get ideas.

yours is a pretty standard mid-century modern prairie style split level. without more pics of where you want the deck, it's impossible to suggest a design. with an older home you have some decisions to make...how is the plumbing? the roof?.how old is the HVAC system? how well is it insulated?are you going to keep the existing landscaping or do something different? etc., etc.....the biggest issue being how much are you looking to spend right off the bat?..

Contemporary cross gable roof.

If your parents sold you a house at or below market cost don't worry about the valuable aspect unless you're just trying to flip it. Keep the styling in line with your local area and similar to what your neighbors have. If your house stands out too much it can lower the value.

I assume this is the front of the house, you might like a paver-brick walkway instead of that poured concrete.

Make the windows pop with a contrasting color to the brown brick and...

Has anyone opened one of these car boosters up before ? / Made one themselves ?

It seems like an interesting project.

Throw in 10x 18650 batteries in there, steal internals from a non working unit and get a crazy amount of boosting power.


All i'm finding online are people using big heavy car batteries as a solution, which isn't practical for an every day throw in your car sort of solution.

I just saw a youtube vid of something like this. I used to use the plug in chargers and the booster packs that were 12lbs; essentially a small car battery with 2 alligator clips.

I'm curious as to how these tiny things can jump a car 20 times or whatever they're claiming. They're all about $100 a piece, but in reality Its $20 of batteries, connections, and a plastic housing. Seems like a perfect project for /diy/ to make on the cheap.
>>
>>950663

Most of them use a single soft prismatic LIPO cell. I doubt you'd get enough amps to jump a car out of 18650's unless you get the high output kind used in tools and such, but those only have a ~2ah capacity.
>>
>>950663
Mine didn't have 18650s, it had a small sealed lead acid battery.

It was fucking shit. 2 weeks after giving it its' quarterly charge I needed it and it barely gave me enough to turn er over.

Such is life when you get a bargain from Lidl. I'll just keep a spare battery on the boat from now on

I don't know shit about eelectronix.

My dental chair already has a recline via a "momentary on/off/momentary on" rocker footswitch. I'd prefer to add a momentary handswitch to also control the recline. Is it as simple as adding an additional set of wires (picture #2) out of this red thing I circled in picture #1?

Do I need diodes or any other thing so I don't blow this chair motor up?

Thanks.

Probably.. actually, almost certainly, as long as the switch you get is rated for the same load as the one you are duplicating.

And you use wires rated for the same load, the hand-switch shell is properly constructed, etc and so on.
>>
>>949389
I'm not sure how your switch switches, but its very likely you will make a short if you use both switches at the same time, to different positions. If its a simple on/off switch that doesn't cross polarities then it would work without problems though. 2 switches in parallel usually isn't ideal, but since its just a momentary switch then it should work just fine.
>>
>>949451
What's wrong with having two switches in parallel? Even if both switches are activated, all it would do is have a reduced wire resistance right?

Building resonant bodies out of wood is a high art, you won't pick it up from a YT tutorial. It takes the material to the extreme and requires a lot of experience in selecting the right woods, carefully shaping them without disturbing their structure, connecting them with incredible precision, and doing it all while keeping track of the sound characteristics. It requires years of apprenticeship and mastery.

Recorders are easier. Electric guitars are very easy, there's very few parameters to control....

Yes. There are really two ways to go about lutherie. The first is to expect the instruments you built to be on the same level as professionally made lutes, violins, harps, etc. But here's the thing about that. All modern instruments have undergone hundreds, if not thousands, of years of evolution. Improvements and crafting techniques passed from master to master for generations. If you're trying to build an instrument that has never been built before, you will be disappointed if you want it to work as well...

I don't know anymore where exactly I read this, but I think the wooden circles are not made with a lathe, but by glueing pieces of veneer together around a round template. This might not be for banjos though, but for actual toms.
You might also find the Watson & Bailey plans helpful. Never studied them myself, since I always was more interested in the mandolin/mandola plans, but I think they're pretty in depth.
