I have this amber TTL monitor that seems to be defective-not working, has no burn in at all so must be low hour

I only get power LED when turning ona nd heaters but nothing else, now at first I thought uit was just waiting for signal but after trying multiple 8bit Hercules video-cards I am starting to suspect the monitor might have a fault in it.
I have no other monitor to verify that indeed it could be the monitor but am very sure it is

The monitor has 3 IC a TDA2593,TDA1170N and a 74LS136W which I suspect might be the problem, but how can I verify that indeed...

Instructions on how to clean your oven:

Remove the oven racks from the oven and any other obstacles that might bother you while you’re cleaning the oven.
Heat up your oven to a moderately high temperature so that the sticky grease turns into ash. After a couple of minutes, turn off your oven.
Sprinkle the baking soda on the different over spilled areas of the oven, afterward, spray water on the sprinkled baking soda and get it nicely moist and get it to a level where it’s converted into a paste.
Let it sit overnight in order to let the baking soda eat through the sticky grimes.clean your oven
On the next day grab a cleaning cloth and start wiping the baking soda from the oven (Hint: to know that you’re on the right track, check the cleaning cloth and its color should be brownish, which are the dirty, sticky grease you just cleaned off from the oven)
Use a little amount of vinegar (about two tablespoons) mixed with water to eliminate the dried off pasty baking soda remaining since vinegar reacts with baking soda and foams up which can be easily wiped off with a cloth!
Do a final wipe with a dry cloth and replace the racks back and the remaining tools back into the oven, and there you have! A nice clean oven!

The headphone jack is usually a seperate detachable piece from the phone that you can buy for like 4 bucks from any vendor.

Even if it isnt detachable its worth having a look for the same phone models jack piece so it fits snug with the rest of the phone.

Hey guys. I want to put a clothes washer (and dryer) in my kitchen. The house currently has none. Supplying water is no big deal as the supply lines are run in the attic space. The drain is my problem. The house is on a slab and has no basement or crawl space. The nearest drain is on the other side of the kitchen where the kitchen sink is. Since its a galley style kitchen their are doors on either end of the kitchen, isolating the only side I have space for the washer from the only side with the drain. How would I drain the washer?

I'd like to do this without resorting to a portable washer or busting up the flood and slab. Is this possible?

Then you can't put it there. You need to drain either directly outside, or into a nearby drain. Run a hose, run PVC. Who cares, we can't do it for you, and the water wont disappear.

Hi /diy/

I am wondering if an electronic part like this exists. I tried Google but I have no idea what it may be called, I tried "electronic that moves up and down", "pumping electronic component" etc.

Pic related. It's simply a part that can be programmed to move up and down.

There is not much soldering involved in building robots, if you want it that way.

Method #1: you use a rasberry pi as the brains, and it has one camera port on it. you slave a arduino mega to that to act as an input/output interface through USB, to operate motor controllers, to run stepper motor drivers, to make stepper motors turn

Power source, switch rated for voltage of power source(amps shouldn't matter with an led), resistor if necessary, led, power source.

Use a calculator online to determine if a resistor is needed, all you need to know is voltage, led color, and how many leds. It'll give you a resistor value, and some even tell you where to put it and how to wire leds in parallel or series to fit them all.

I'm in an apartment and I don't want to screw with the wall studs or ceiling joists. There isn't enough space for a turtledog stand or whatever else. My only option is to build a frame that spans the width of the room and stabilize it.

Option 1 is a horizontal 2x2 ontop of 2 2x1 nailed together and have the hammock eyebolted to the vertical 2x1.

Option 2 is a horizontal 2x2 betwen 2 2x1 with gussets at each end and the hammock eyebolted to the horizontal.

option 2 in doubling up the material holding you up, but mounting in option one with cripples under the top piece, and make sure the top piece is mounted in such a way that the load going into it is though it's thickest plane

and good luck having this hold you up i wouldn't build this with anything smaller than 2x4 pieces, though i'd probably double them up and make a frame

or i'd stop being a bitch and use steel 2x2 square tubing and weld it quick and dirty, and never have to worry about it shaking apart
>>
>>1012262

Other than the fact that 2x2 and 2x1(?) trying to hold up the weight of a person, and my understanding that you are only building one of these "frames" I really dont think this will work for anything useful.

What keeps the frame from just falling over from its own weight, two legs of lumber won't do that. Plus I dont think I've ever seen a place actually sell a "2x1" board.

option 2 will likely have eyebolts on the side

you have no recovery after the diodeclipping.
the diodes clip the signal down to their forward voltage.

regular diodes clip around 0.4-0.5 volts, germanium and shottkys can go as low as 0.15v

the simplest fix would be to use 4 diodes instead of two, to in series each way.

I'll see if i cant throw up a simulation to illustrate my point.
>>
>>1012330
i made you a simple illustration.
as you can see, the stage with one diode each way clamps the signal down to +-580mv.
while the stage with four diodes clip at over a volt.

usually, clipping based pedals have a second gain stage to bring the signal up again after the diodes, but I've made a couple of single stage ones like this using diodes in series to get a higher signal.

you can also experiment with different diodes and having one in one direction and two in the other to get asymmetrical...

Shielding isn't really a problem as long as you stay away from electrical lines. If you have to cross them do it at 90 degrees.

RG59 is probably what you have, just run some RG6 to your modem and you'll be fine.
>>
>>1012038
It comes in right at the main electrical box. Plus it needs to run 8 ft on an external wall. It wont get much sun, but it will get pounded by storms regardless, so a good shield is paramount in everything. Again, this is old wiring so nothing is properly shielded, thus new shielding.

I feel your pain, was looking at the quad shielded. Not sure if anything will improve since the wire outside to the house is old as whats inside (not to mention the hobby box crappy cable I ran 15 years ago). Have a booster and their cable their connectors bla, bla. Now I'm going to move the modem to the front of the line in an attempt to stabilize the internet. Paying a megaasston for some BS HD package full of junk and have to kick the damn modem 1x a week and I'll be damned if I let the hacks into my house to butcher things.

What wood would be best for this? Do I need to use a finisher to make it food safe? I assume I just get a slab of treetrunk, sand it till its nice and smooth, oil it and then maybe seal it?

I have one of those.
Our wooden chopping board isn't even oiled or anything.

It's just a single big cutout from a log.

No-nothing is the safest way to make sure there's no contamination. If you're worried about bacteria buildup after a few years, you sand it back down again. No big deal because it's already a huge chunk of wood.

Fair enough, I am a computer science graduate student, so that's definitely a possibility.

Anyway, I am trying to rid the original nasty fence (which was basically rotting) with something else. Digging is out of the question, because literally my entire yard is inundated with stones. So, instead of creating new posts, I went with the eyelet and rope look. I think it looks good, actually.

Anyway, the bundles of rope I bought basically end at the photo. There is an opportunity to do either 1) cut the rope; or 2) keep the rope as is and add something. My question is what does 4chan think I should do? The possibility for something else is also on the table.

>>1011363
If that is your 'rotting' fence in the background there... it is practically brand new. I can't really believe the posts are rotting already.

If they are, get galvanized fence posts and replace with them.

You can drink it but it won't do much. You need at LEAST two weeks fermentation (like the Mr. Beer kits) and grain kits usually need longer. The air bubbles slow down big time/stop after a few days that's normal but it's still working. Then you need it to set for at least two weeks in the bottle to carbonate. When you bottle you add a little sugar and that jump starts the process again so it can make more alcohol. But this time the air can't escape so it's forced back into the drink as carbonation. So basically no, 12 day old fermentation isn't...

Nope. You have to plug this TV card in to the TV coaxial cable that comes out of the ground. If your provider uses TV-over-IP(ethernet->settop box -> TV) or a normal decoder box between the coax and your normal TV, you're fucked.

And no, your PC can not decode it if it's scrambled.


All this card allows you to do is record programs like a DVR.
