CCTV is generally an analog system. So you need dedicated wires to each camera, and some sort of capture card for the cameras. You can use baluns and use cat5, so you can reuse ethernet wiring if you have it already. For capture, there are USB versions available, so maybe you could get away with using a laptop? The cameras for analog are dirt cheap for low/medium resolution, and capture cards are cheap, if you have a dedicated box with old style PCI slots. Anyway, it's possible, but not overly likely you can get away without a dedicated box for CCTV.

IP cameras are more expensive, but still cheap. Problem being, the really cheap ones are locked to vendor software if you want to do more than browse to the camera's built in website. Ways around are found, but it varies from device to device. If you use the vendor services, often it pipes video out of your house, to their "secure" servers, so you can use their phone and webapps to view your camera from anywhere. These are companies that don't think to turn off telnet on the devices they sell. The quotes around secure should be highlighted. And underlined. And have a an image of giggling girls behind it.

Analog systems are not worth it. You may save a little upfront, but IP cameras are just so much more practical. If you have fast wifi you can buy a single IP camera without any other gear, that streams live 720p to your mobile phone or laptop whenever it detects movement.

If you know how to build a desktop computer it will be easy to built a network video recorder (NVR) that records IP cameras transmitted via wifi or lan. Or you can buy one:

i think your best solution is to get something like a Costco kit, all assembled with 4 cameras and a video recorder. you can probably get one with VGA or HDMI output so you can use an old monitor to view it. and with an ethernet port, or wifi, so you can pull out interesting bits of video.

computers are not well adapted to this task, coz too noisy, too much power, will die soon of they're run 24/7, probably will not restart recording if they reboot coz of power failure, or coz of windows updates.

the solder job is really shit and is 99% the problem

>the solder job is really shit and is 99% the problem
im not really investing much time, that's why im requesting a pic from the other board. I dont have the time to do try all the pins

>>1122350
yeah but you also aren't investing any skill

I fucking hate it, there is about ten holders somewhere between me and China, and I can't get it.

what do you expect it to do?

Yep, it works Fine. Better if it's a small room

>>1122109
Identical heating to plain candles. Might put less soot into your lungs because some will be caught on the pot, might produce potentially deadly carbon monoxide if the airflow is insufficient.

>>1122052
call your supplier, this is not diy

>>1122053
Okay ;-;

depends. usually the night meter is for off peak rates tied to a water heater or something. i'd guess the day meter is what you want.

You wan to build something that is mass produced for relatively inexpensive?

Cast a block of iron or aluminum, then use your 6-axis CNC machine to cut away all the bits you don't need.

is there any kind of business where i can give the designs and build, pistons etc ? sadly dont have enough tools

i've never messed with diode lasers, but i have built a ruby laser that would burn through a razor blade and was powered off a car battery.

quite simply, your laser isn't lasing. or in laymens terms, the photons waves aren't aligned.

are your lenses made from polarized materials?

lasers work by reflecting light around a chamber with one exit and to get through the exit the wave has to be traveling directly out the exit as well as all the photons waves being aligned,

even if a photon is traveling in the right direction if its waveform is off it just gets reflected back into the chamber by a polarized material.

no polarized material and its just going to behave like a flashlight with high defraction.

>>1121685
Interesting, Im a complete amateur when it comes to working with lasers so this is all very helpful. Im not sure whether or not my laser is made of polarized materials, do you know how I might check? Seperately, since Ive seriously considered getting a new diode altogether, and the more powerful the better, how difficult/expensive was the ruby laser you built? The larger battery shouldnt be a problem in the grand scheme of the whole project I think.

>>1121685
Congrats on building a ruby laser, but your theoretical knowledge is horribly flawed.

1. The wave does not need to be traveling exactly perpendicular to the exit mirror. The beams go in all directions but the positive feedback formed by the parallel mirrors is what forms the singular beam.

2. The exit mirror does not filter or affect the wavelength of the laser. The laser medium is the one and only thing defining it.

3. Polarization has nothing to do with wave length (assuming that's what you mean by waveform?).

>I'm horrified at how ghetto this is but I also can't see a reason why it wouldn't work

I was gonna say there might be a problem if that software (in a nutshell) went through Windows instead of actually interfacing directly with the mouse itself. But it explicitly states that you can use more than one mouse at a time, so you're in the clear there.

Go for it, bruv.


>You can get a mouse for the cost of a Happy Meal, a full-featured videogame controller for $20, but if you want something unconventional like a single freaking knob that you can control software with you're looking at something on the order of $50-$100 even though it's ancient technology that China can produce for literal pennies.

My hobbies are something along the lines of industrial automation, process technology, electronics, and robots. Your dilemma is not exclusive to any market. EVERYTHING goes way the fuck up in cost the second you step out of typical consumer goods. Discreet electronics components can see price differences as high as THREE ORDERS OF MAGNITUDE when talking singles vs. bulk orders of 100,000 or more. Never even mind the cost of things that essentially aren't used by the layman.

While I'm in a position to fully appreciate the insane standard of living that highly-optimized mass manufacturing for a huge market has provided, I can't help but look at it from a glass-half-empty perspective a lot of the time. At least raw materials are competitive enough that I can get those for not TOO much more than a manufacturer would pay.

Arduino Leonardo is a USB HID

>>1121563
I hear you dude. The saddest part of the problem here is actual device/peripheral manufacturers not seeing the value in bringing more devices like these to the market.

>>1121564
Thanks, I have heard of it but don't know anything about it. And again I'm pretty eletronics ignorant. I think even that would ultimately cost significantly more not even counting the time investment in learning/building.

There is a part of me that wants to actually build stuff like this but I have a bad habit of picking up hobbies and then never getting anywhere with them. Maybe some day...

Jesus christ. Google cracked porcelain effect.

Try enameling it before you bake it.

The expansion caused by heating and cooling might do the trick.

Then after its baked finish with a clear enamel, sand until its even, then polish the shit out of it.

A lot of styles like this were fads caused by someone fucking something up but somehow making it look good. Kinda like ripped blue jeans and oversized clothes... Both trends caused by people making hand-me-downs look good.

>>1121555
Potter here. In ClayLand this surface effect called crazing, or crackilng if it's a feature rather than a flaw (shh), caused by a high coefficient of thermal expansion between the glaze and base ceramic. The glaze shrinks more than the clay, hence it forms fissures upon cooling. The lines are enhanced by rubbing ink into them and cleaning it off the rest of the surface.

Thanks to modern science and shit, this effect is easily replicated with acrylic paints! You want to buy a clear or transparent gloss acrylic crackle glaze. I'll betcha it works by drying super fast and crazing to relieve the surface tension. In general, thick applications give bigger plates and thin applications give more and finer lines.

Step 1 - base color(s)
2 - crackle glaze
3 - rub india ink into cracks, wipe off
4 - gold shit

There are a number of approaches. You can use a dremel to carefully carve a slot for a flathead screwdriver. Alternatively, you can just drill out the top portion and bypass it. It's a difficult operation, but you can do it with good tools and a steady hand.

Just put a piece of fabric or paper over it and push hard

>You can use a dremel to carefully carve a slot for a flathead screwdriver.

This meme needs to end, because it simply doesnt work well and you destroy everything around it.

You think a head with soft metal that already stripped is going to take being heated up with more material removed?

You go to turn the screw and half of the head flies off.

OP Needs an easy out

you can get completed clothes for less than the price of the cloth needed to make them. if you want cheap, try modifying thrift store clothes.

It's very cost effective. You can get a lot of fabrics for 2-5 bucks a yard at stores like Joann. So easily 10 bucks or less per simple garment. They have sales on everything on rotation and I get a weekly 50% off coupon.

The expensive part might be your sewing machine and serger but I got mine for free from relatives and Craigslist.

it's not easy but you can save a ton of money

but yeah goodwill clothes are dirt ass cheap so you're only saving compared to buying new clothes

Pay a junkie to do it

Lol, don't. Wood is never fully dry unless it's out of the oven, the water content could be enough to shock you, you don't want to take risks with high voltage and high current.
Use a PVC tube or something like that instead if it's completely necessary.
If the line is sagging dangerously, ask the power company or somebody else to fix it.

>>1120581
No. It's not touching the line you're really worried about. It actually creates a potential difference near the line through the ground so simply standing too close can shock you. A severed power line is basically just a really really big capacitor just desperate to discharge.

Think of what you'll need to fix her place. Looks like you got the basics. I'd drop the hammer, nails, and duct tape though, she'll only get herself into trouble with those. Maybe go for a cheap wrench set instead of the adjustable, because you're more likely to need the tools than she will.

I did this for my girlfriend. Worked out well since I didn't need to remember my toolbox in the car and I could fix that thing she never mentioned needs fixing until I was already visiting.

have done simple gutters, but for a large run you're gonna need two people

it's not that complicated...cut to size, join the pieces, snap on the brackets, screw to facia

make sure they are installed properly under the drip edge or you will have water problems
