I am stuck on Samsung LED though (model UN55FH6030FXZA). It has no backlight, passes the flashlight test, but displays backwards text. It also seems to blink 6 times as an error code above the power button. I called Samsung and they said the error code signifies nothing specifically. The person I got it from said the TV was doing some funny stuff before it finally cut off. Supposedly it would randomly display black/white fuzz and some other weird things. Any guesses on what I should replace? Accessing the LED driver or backlight inverter( whichever it is) will be tricky because...

here's a closeup of the power supply board, all the capacitors look okay.
>>940439
I would suspect the main board more than the power supply. If it can light up the screen long enough to display an error, then it seems that the controller is not telling the screen to turn on, so it doesn't. If the error was displayed backwards, that would only happen if the controller didn't know how to output to the screen properly, also pointing to the main board as the culprit.
>>940481
Thanks for the help, the screen never lights up actually. the error code is displayed as the power light blinking 6 times. I'm thinking it has to be the main board too. I'm afraid the power board may have shorted out the main board so I'm not going to install a new main board without changing the power board at the same time. I may be wrong as I have very little experience but I don't want to chance ruining the new main board.
So i have found a large slab of maple in the form of an 4 foot x 3 feet. Its shaped as a rounded rectangle, and at least = 1.5" . How would you go about cutting this without a cabinet saw?
I own a bosch 4000 contractor with no accessories and very little space (its basically storage right now, sitting in a brooklyn basement)
or i can utilize a 6 1/2" - 7 1/4" circ cutting saw.
Plan .8.0 right now is to take a circ saw using a 4 ft level clamped to the table along desired cut.
I'd like this table to be of high quality as my new work bench. After i would like to something modern such as add functions of electricity(lights, usb ports, integrated outlets, etc)
Also: I'd like to build this bench without screws or nails if possible, something where the legs square up to the top of a table through a hole flush the legs insert (rectangular or spherical?)
>>940004
Yep, a circular saw with a clamped straightedge or level as you suggested. Take your time as its difficult to get perfectly parallel cuts. But if its for a workbench it might not matter as much as, say, a coffee table. You could also build a jig of some type.
>>940025
What would you think about taking two cuts?
1st to get very close to final width
2nd to trim to size, using about a portion of the thickness of the saw blade?
This table will be the heart of all my operations be it electronic, plastic, or wood. I'd like to use it for promotion as well in the business im hoping to soon open. (local handyman/technician)
>>940035
a circular saw is not the appropriate tool for that second cut. You should focus more on knowing how to be a handyman/technician and less on the table you want to promote yourself with.

That's not entirely true. It's rather basic logic, but it's certainly more than just passing the chirp and echo signals directly through.
That's a big chassis.

Yank out all the ultrasonic sensors, they're shit. Put in a kinect, depth camera, or neato laser scanner, then put in something that can run Robot Operating System(ROS) and process that shit. Then do SLAM. If it's not doing SLAM then it's barely a robot

As long as you have a certification go ahead. Can't do it in most places if you don't have one.

About seven months ago I made a post about Diaper Boy whom I caught with his drawers off on my gamecam and he also vandalized my trailer on my rural property, which I do not dwell on. I filed an incident report with the sheriff's department and they did zilch. After two months I referred this incident to the juvenile probation department and a probation officer conducted an investigation. It has been a long road but finally last Wednesday 06Jan15 that teenage freak went before the judge and he plead guilty to trespassing and was granted 6 months probation. It is closure...

I remember this thread!
Good work getting something done about it.
this story brought me closure. I was wondering how you went with your shit goblin problem.
Well placed cam.
How the hell did you know who it was?
Did he come in the same way he went out?
As seen in the pic?
I'm doing some dyi wart removal. It's a periungual wart, i.e. around the fingernail. I have been applying salicylic acid daily and gradually removed dying tissue, for about three weeks. At times, it has been very swollen and painful.
Today, a huge, squishy lump came off without any pain. Considering the depth of the crater and the pink-red fleshy color at the bottom, I am hoping I am rid of the bitch for good.
The important question is how to proceed from here: leave it the fuck alone and see what grows back, or to keep removing tissue and applying acid.
>>935948
Just go to the doctor
>>935950
I have been consulting with two close relatives who are doctors. It's all safe and sound and by the book.
I primarily hope to hear from someone with first hand experience on how to tell you've got the whole root.
>>935956
Well fair enough then
What is a safe way to discharge a large capacitor if you don't have a multimeter to check it and aren't sure if it's charged? I'm finally taking stuff apart for components so I can begin tinkering.
>>940675
Screwdriver and gloves. Then finger test it all.
>>940675
touch it to a grounded wire
>>940675
~5k resistor
power/sandstone type is better ( for your fingers to hold )
bend terminals to cap distance. hold in middle. contact cap for a few seconds.
Are there any refrigerants that are legal and safe to vent to the atmosphere? I have a dehumidifier manufactured in 2010 that I'm disassembling to gather electronics and other components to start a useful tinkering collection.
carbon dioxide.

Ok, I know enough about electricity to get myself thoroughly killed with it.
Before I spend quite a long time trying to research this, possibly getting it wrong, and killing myself, I figure I'll ask someone who knows:
What's an estimate for the lowest price point for the setup necessary to make stuff like pic related?
(Safely is of course possible, but that'll be what I look into depending on the answer to the first question.)
Any other thoughts/opinions are welcome as well.

You need an electron particle accelerator unfortunately.

>Many other physicists, experimenters, and artists studied Lichtenberg figures over the next two hundred years. Notable 19th and 20th century researchers included physicists Gaston Planté and Peter T. Riess (mid-1850's). In the late 1800's, French artist and scientist Etienne Leopold Trouvelot, created "Trouvelot figures" - now known to be photographic Lichtenberg figures - using a Ruhmkorff coil (a type of high voltage transformer) as a high voltage source.
>In the video a more modern Wimshurst electrostatic generator is used as the high voltage source instead of an electrophorus, as originally used by Lichtenberg, but the principles are otherwise the same. In the video, branching positive Lichtenberg figures are created first, followed by shell-shaped negative Lichtenberg figures.

You could just charge it as a capacitor using typical methods. You won't get those massive voltages unless you make a Tesla Coil.
I suggest using a microwave transformer for these types of things on smaller scales. Learn how to use those first then move on.
Hello /diy/. I've been reading into jewelry making and was wondering what guides, books and other essentials and resources any of you would recommend out there.
I really like circuitry jewelry like pic related, and was thinking of making it for fun and maybe profit.
I know my way around a workshop, so have at it in what you recommend.
im a guy. I use to make glass jewelry and sometimes still do.
this is the best advice i was ever given make 20 different things. if something sells make two more similar ones.
also circuit boards have those sharp things.
>>940380
Thanks for the sales help.
"Sharp things?" If you mean the edges, they can be sanded down to be smooth.
>>940380
Good info.
GF makes jewelry full time. Circuit jewelry looks cool but I'm not sure how popular it is with women. A quick Etsy search would work.
I think sharp things refers to the contacts on thru-hole boards.
As for guides. Unless you want to go into higher level stuff like casting metals, faceting stones, or other things like that. Just trial and error and maybe youtube would be the way to go.

Pic related.
You can blast with that compressor but not very fast. 10 CFM would be a minimum and even that is low. You will get a few minutes of blast time with a small gun nozzle, then wait for your tank to fill up, then a few minutes, then wait for compressor to cool, then fill up. That's not a constant duty cycle compressor. They even say 1000h pump life; industrial compressors will go many times that, screw compressors can run contiuously for years.
>>940210
Serious blasting requires serious power. I can afford an industrial blast pot and all the gear plus a compresor to run it,, but that's not worth it when the alternative is easy.
I take my truck and motorcycle frames etc to a local monument company. Monument companies use industrial sandblasters to cut artwork and letters in gravestones. They nearly all do sandblasting because it's good side cash.
You will die of old age trying to do it yourself with babby blasters. All they are good for is small parts. Don't even bother for radiators and large truck parts. I wouldn't use a hobby blaster for those jobs if everything were free.
You can rent an industrial compressor, blast pot and gear and buy blast media from a rental center if you want but I wouldn't do that for those jobs either because you'd have to hurry insanely to get it all done in reasonable time so you don't rent for extra days.
Some things are DIY. I have a lathe, mill, welders, and a shitload of gear. No way would I bother with blasting unless I had very high profitable volumes of work.
Pay the nice man. My last Harley frame and swingarm was fifty bucks. Even if you spend a few hundred to do your listed load that's a LOT less than a serious compressor and blast pot.
Hey /diy/.
I'm planning a custom knife. How do I add serrations to it the right way?
>>940987
look at what existing knives do
>>940987
>I'm planning a custom knife. How do I add serrations to it the right way?
knife companies use a CNC grinder.
I'd think you could build one for <$200; it would be just a 3-axis positioning setup (like a 3D printer) but with a grinding motor on it instead of a 3d print head. kinda expensive and complicated tho
much cheaper & simpler would be to get a diamond honing steel and use that instead
general process for handmade knives will be to make it straight, then add serrations after heat-treat with EDM stones and an angled jig. a few may use water-cooled grinding setups.

Yes, it is called a table

R8 my college student coffee tables I made for cheap. Took a few hours to make them and about $30 a piece in the end.
>>940578
underside for fun??? Not pictured: the screws I put in the back through the legs because I wasn't done yet when I was taking this pic.
pretty slick anon.
i would attach the powerboards on the inside of the leg however, for cleanliness.
>MDF top
Nooooo thank you. Set a glass of ice water down even once without a coaster and the top is ruined. That water ring will be highly visible and never come out. I truly appreciate you /diy/ing something and it looks s lot nice than most lumber coffee tables. That said, I probably would have just got a coffee table for free/spent the $30 for a coffee table off Craigslist. Would look more like adult furniture. The effort you put into it is definitely 5/7 (minus the power strip, need to clean that up) but it's very "bachelor pad-ish"
