Does anybody have any ideas (hopefully cheap) on how I can make a stand to hold this light? I went to home depot and they had a similar one of plastic and the guy was saying to remove the bottom and drill a hole connecting the light to a PVC pipe as the stand. But the light I have is heavier (almost glass like) and the bottom isn't removable. I just need something to hold the light in the air like in the picture shown but I can't tell how they're doing it. Thanks in advance
Here's the light I have
Really strong glue and some good guage wire. Your not going to be touching it often so this will do fine plus you can bend the wire to hide it as much as possible.

And do what exactly? glue it around the black base, and hang from ceiling?
I do a lot of at home vehicle repair, stuff that requires socket wrenches, screwdrivers, Allen keys, even misc electrical... But I don't have a garage. This means I have to drag my tools out to my vehicle. I also have to do this when working on my family's cars too. I figure a bunch of you guys do too. Any recommendations for a good portable toolbox to keep my tools organized? Maybe something with drawers.
>>1008847
I have a Matco on wheels I keep chained to the bed near the cab and my truck has a lift for the tailgate when I need to put it on or take it off.
Something like you have pictured with one of those small, collapsible dollies will work well.
>>1008847
Tons of little drawers? 7 or 8 drawer machinist chest. Fewer larger drawers? 3 drawer machinist chest. Ton of larger drawers? Get a 'top box' (picture related) and something to roll it around on cause it will be too big too carry.
Fuck drawers? Cantilever tool box.
Fuck heavy tool boxes? Tool bag or bags.
Hey, I want a plastic tool box! Well, fuck you.
Hey guys I bought this air wrench on eBay. I don't have it in hand yet. Dun goofed I know. I was informed after I bought it that there's no way to tell the condition of air tools unless you have it in hand, since you can't see if it's been well lubed throughout its use.
What condition do you think it's in?
Are tools used in professional environments (like this one I bought) typically well maintained and lubricated until they decommission them? I'm hoping that this gun was run on a lubricated line but now I'm afraid I wasted my money.
We can't really tell by looking at a photo.
You have to ask why is it being sold? Personally if I had a good working solid tool I wouldn't have a need to sell it. Even if it got little use, the amount you'd potentially lose on its resale for me would be more than enough reason just to put it in the tool shed. Unless its bankrupt stock of course.
If it's been used professionally however, a good indication of its user would be it's new price, there's a chance while it would be lubed and serviced, people who work for companies don't really take too much care of tools because they haven't had do buy it.
You just gotta hope you did good.
>>1008749
Thankfully air tools can often be refurbished pretty easily, and can tolerate a lot of abuse, and mid-range ones aren't particularly expensive compared to electric tools.
Pros don't get rid of their tools until they're on the verge of falling apart and held together by baling wire and guerilla glue and can no longer deliver reliable service. Then they either give them to the new guy as a practical joke or they sell them to n00bs on eBay.
Long story short, you're fucked.

Hey Lads, I'm about to order some fabric for a backpack kind of thing that I'm gonna make and I'm stuck between normal cotton canvas and some shit called Cordura. I was going to use canvas as I know what its going to look and feel, but from what I've, the synthetic stuff is better in just about every way.
Anyone had experience with cordura?
>>1008021
Voting for 1000D cordura nylon. Extremely durable lasts through years of abuse, and very water resistant, as in carry it through a torrential downpour and your stuff stays dry.
No reason to use anything else unless you need it to be ultralight.
>>1008024
Quite stiff though so it might be more difficult to sew.
>>1008021
Cordura all the way.
All of my gear is made from fabric i acquired through 'owf inc' been very happy with their prices and service
Last 3 days I've been doing some trial and error home anodizing and finally got a result that worked.
Often you just want a piece of aluminium for a project that needs to be corrosion resistant, non conductive and 'pretty' with some kind of different colour. But big places don't want anything to do with hobby people and normally this involves using sulphuric acid... which is fun, but hard to get and WILL to fuck your shit up if you get it on yourself or anything else you don't want burnt and dissolved.
In my case, I just wanted a couple of bolsters done up and slapped on a knife I was making
Solution- Sodium Bisulphate which is normally found in hardware stores as PH-Down for pools and spas.
Its still nasty, it will fuck your shit up and anything it touches, but its:
>A- cheap
>B- easy to get
>C- wont put you on a terrorist watch list and can be tipped down the sink when you're done
Ratio I was using was 10 teaspoons of the powder for 250ml (1 cup) of cold tap water
Put it in a clean jar, swizz it around until its gone a cloudy colour and all the grains are dissolved
In the meantime lets get a list of stuff you need-
Distilled water- for rinsing parts
Methylated spirits/alcohol- for cleaning parts
Packet of PH-Down
Rubber gloves (clean)
Measuring cup
Saucepan
Glass Jar or acid resistant plastic bucket
Power-supply- around 6-12v and 1-2 amps (1000-2000ma)
Aluminium Wire- 4-5mm 1ft long
Aluminium wire- 2-3mm and 1ft long
Paper cloths
Non-ferrous scrubber
Old toothbrush
>>1007950
Most important is the parts prep and connection.
With your aluminium part it must be excruciatingly clean-
Gloves on
Give it a dunk in some soapy water and scrub it clean as you can
Once that's done, paper cloth and couple of drops of metho-spirit to get any final residue off it (do not touch it with bare hands!)
Dunk it in some distilled water and let it soak while you set up the rig
Connection to the piece is very important to the anodizing process so I recommend that you pin-it with a small length of aluminium wire (2-3mm) and anchor it firmly in the piece.
Dangling it off a wire looped into the solution doesn't work, the wire will anodize and become non conductive
Alternatively- you can wrap the wire around it until it is firmly held in place
In the acid tank you can only have aluminium in there, though pure lead will do for the anode end on a length of aluminium wire
Roughly the size of the anode = size of the work you're anodizing
>>1007957
Power supplies as long as they pump out some decent amperage will do the job 1-2 amps seems to be fine for small pieces, you can get them out of old laptops battery chargers, car battery chargers and various utility devices- as long as they're DC and around 6-12v = all good
The Anode I just made up out of some 5mm aluminium wire into a coil with an end poking out of the acid tank you can wrap the wire around or use an alligator clip
This is where the (-) Negative goes
The bar across the top for suspending the work pieces, same type of wire, squashed flat, couple of holes drilled into it
This is where the (+) Positive goes
When you dangle the work piece in the solution, make sure its deep enough to be covered and won't touch the (-) negative
Tiny bubbles will come off both pieces, generally this is Hydrogen in trace amounts and not really a risk, but you might also get a sulphide smell too which means get a bit of ventilation going
Run this powered up for about 60-120min or until it stops bubbling
(This is not exactly high excitement for science!)
I'm going to make some Kentucky stick chairs, but I don't like this shitty, "staple the wire" look. What's a good way to secure the wire without looking like trash?
extra points of the wire is completely concealed.

Post this on /adv/ and they came up with a decent room idea of using it for shuffleboard. Which I'm strongly considering -- but now I need to make it into a room that won't make people sick to enter.
Any advice for the flooring to match the window trim or a color to not make it as miserable? Or do the windows really need to go to salvage the room?
>>1007265
The problem with the room is the color of the paint on the walls. This is very easy to fix. Paint them white or something not ridiculous. Knotty pine does not go with lime green. It looks like a bamboo jungle themed mini golf snack bar.
>>1007265
I'd go with a wood floor and change the paint. The wood around the windows is loud (knotty pine?) but not bad so you need to go with something muted for the walls and floors. The green just makes me want to puke. Too much going on. So go with a medium wood or lighter wood on the floors and probably an off white or something else thats pretty neutral for the paint. Then maybe some throw rugs? Depends on what you are going for.
What is the deal with that room? Is it a dining room? A weird addition? Its got a ton of outlets (hope you have at least 2 circuits) and the weird door at the end. 3 lights? What? Storytime please.
>>1007270
>It looks like a bamboo jungle themed mini golf snack bar.
This comment made my day.
>>1007273
Don't even know myself. Purchased the home as a foreclosure and before it was that it was abandoned. Realtor advised it was both a great sunroom and place for growing weed. Which I'm told is important to have outlets everywhere.
It's definitely a weird layout. Aside from that door at the end that leads into the living room, it also has two windows to the interior on the other side (where the photo was taken) that look into the kitchen. No entry from the kitchen though.
First I was thinking pool table and a small bar, but the walls might be a little too close for it since it's 26 x 10. And for a bar it's too well lit.
I just read up on the story of the "Killdozer" and it really got me thinking.
What is the practicality and plausibility of a "killdozer suit" if you will?
Basically, im thinking of a rectangular prism shaped block of rediculously thick armor plating, similar to the kind the "killdozer" used, and with cooling and air flow shit set up inside, with gun ports as well. Would it be possible, do you think?

Im trying to build a VGA to TTL converter for a mono AMBER monitor
http://www.epanorama.net/faq/vga2rgb/vga2rgbs_ttl.gif
now this diagram shows it uses a 74LS86 ic,but I only have these ones : 74C00N,74C04N,74CO8N and 74C10N
now comparing the diagrams between all them they all seem to be very similar only OR/XOR
and it say they have TTL compatibility
any thoughts ?
Functional completeness famalam
>>1009495
so I cant use nay of the above ICs ?
>>1009498
Couple of things:
- That circuit of yours does nothing to video signal levels, it just combines HSYNC and VSYNC. Ye olde amber monitors wanted TTL video as well.
- Since you don't need speed, you could make a clumsy contraption using those 4 IC types you mentioned. You might need to add input pull-ups, though, since they expect CMOS level inputs.
Anyone taken on doing a drainage system for a house? Hard finding quality info as most people are trying to sell something.
>>1009203
When you say drainage for a house, do you mean waste water or exterior rain water run off?
>>1009203
That looks nice.
We just have a groove carved into the edges of the floor where it meets the wall, and then a couple lines are carved from the wall to the drain in the middle and all water flows like that.
>>1009228
referring to water penetrating a foundation from hydrostatic pressure/earth heave.

help/ideas/guide to build sound horn's to be used with compression drivers for sound reinforcement use.
in other words, how to build pic related.
the story: i have two cheap 2x15" PA cabs, they came with crap 1" compression drivers that are dead. blown up. also note that i live overseas and gear here is expensive. everything has to be imported. so i got a pair of 1.5" chinese B&C clones (comp drivers). they look pretty decent. heres the catch, i dont have horns/waveguides for this things.the only ones available at a local market are designed for 2" drivers and are $80 each. too much.
so im just planning on building my own horns.
the hard part is that there is a lot of theory behind building this things.. small changes can fuck things up (due to small wavelenghts in high frequencies). ive been reading and have some clues on where to start, some dimensions i think could be ok.
but i have no idea on what material i could use or how could i build them.. ive seen some wood ones, but very little info about them, almost none. so thats the main point i think you guys culd help. how can i recycle/build something in the shape of pic related? has curves, curves can be minimized but still...
if someone wants to read more about this things, this is the best page with cleart info ive found;
http://education.lenardaudio.com/en/07_horns.html
and well, thats it. any ideas? any tips? any experience? i know its a log shot but yet who knows, need to make this work.
btw im not so concerned about hi fi, but more with efficency. the plan is to make local underground gigs with this sound system.
(will be a 3 way system, 2x18" subs, 2x15" low-mids and these tweeters. active crossover and 3 power amps, already have the subs and 2x15" and one power amp, will buy the rest soon.)
Thanks!
Where do you live and what shit job do you hold that 160 dollars is too much?
Tell the truth, mom said no.
>>1008963
i know you trolling but just in case:
Chile, southamerica.
you're missing the point, 160 bucks for 2 pieces of shaped plastic is expensive. if it where something more complex, ok. but look at the things. you could argue that they are exactly designed and stuff. but further investigations tells that thats not so true in most cases. (spherical horns with less distortion and propagation paterns beeing a bit of a sound marketing thing). peace my friend. at least you help me bump this thread. thanks
>>1008950
That's really neat, I work in RF and we use horns almost identical to that for our standard gain feed horn antennas used in characterizing patterns of other antennas or getting really good power readings off shit and other shit.
If I where you I would probably use fiberglass.
Carve the interior out of foam then put a plastic base down and coat with fiber glass before vacuum bagging. Even shit countries have fiberglass shits available.
If you can do a little social engineering you can borrow one to make a casting from and not need to carve the foam.
