So guys I have a project in mind but it involves some steel cutting. Problem: I don't have any power tools (torch cutter, plasma cutter, angle grinder, etc.). Is there a simple way to cut steel without these instruments? >Pic not related those aren't the plates
>>925429 Is it worth £3.74 not to drive for 2 hours? Yes it is. I don't know where you got the £2.50 from but yes, i've sooner do nothing and pay £2.50 than drive for an hour, even though i'm a taxi driver.
>>925429 Not to mention wear on the vehicle. This is a penny wise, pound foolish way of thinking. If you really want to save money move to an apartment that's $100 cheaper a month, save $1,200 annual. Quit worrying about $5 is retarded.
You'll notice in my OP picture, the rectangle at the bottom is 40 squares long and 13 squares high. That represents the maximum side profile I have to work with. The square at the top left is the maximum frontal profile. Each square is one foot.
At the bottom left is a line 13 high beside an L shaped line that's 7 high and 3 across the bottom. That's how big my doors are to the backyard and I put those there for scale.
>>923452 well it all depends where do you live? somewhere hot? ac is expensive, blow up a paddling pool infront of your sofa to steep your feet in to keep you cool somewhere cold? wear a jumper. if your heating is even electric.
insulate your house. double glazing, blinds, heavy curtains. curtains over doors. how many rooms/floors? heat/cool a smaller area, live in a bedroom if necessary. keep other doors closed to help insulate from the outside
what electric do you use? lights? switch to cfl/led when... Comment too long. Click here to view the full text.
So I'm building a table for /tg/ shit, and I want to put a projector inside to project whatever I need to show onto the table's surface. Then, of course, i'd put a layer of clear material over that to protect the projection surface.
The question is, what kind of material is best suited for this sort of projection? Is plexiglass or plastic better for protective covering? Would the projector take too much space?
That's actually a pretty dank idea. You would need to shell out quite a bit for a decent projector tho, and especially important will be finding one that will focus at such a short distance (ie floor to surface of table). Plexiglass might be a good protective surface, but you'll need something semi-opaque for the projection to show up on, like a white sheet of some kind. A (perhaps cheaper) alternative would be to put a big flatscreen into the table, but both have challanges
I'd probably use a 4:3 flatpanel bolted under plexiglass in a way that it won't be load-bearing as to protect the screen itself. Any projector that can focus in that short of a distance is gonna set you back quite a bit.
I actually work with projectors and surfaces on a daily basis, and I believe you could use anything white to project on as long as the room is dark enough. The covering for it would be best if it were very clean glass, but reflections are going to suck. You'd be better off just using a durable white surface that has a low-gloss finish. Maybe particle board of some type. If your ceiling is not at least 6 to 8 feet away then you may have trouble getting it to be a big enough image. But if it's closer then it will look better, so do some research on that matter and worry less about the table.
Has anyone got an idea for me of where I can find a jar-like container suitable for the following needs: 1. Not delicate (not like glass). 2. As near these measurements, but not lower than: 45mm opening, 150mm depth. 3. Strong sealing lid - so that the thin oil (Paraffin) I intend keep in it won't seep out. 4. Preferably transparent.
>>925311 coke bottle? a little to deep? old vasaleen tub, tooth paste tube if you clean it out well enough, not transparent though, you can buy plastic viles and plastic test tubes from ebay for dirt cheap, they have screw on lids... probably get 20 for like $10?
How to keep cast iron work tops rust free without much maintenance, and without imparting a greasy feel to it? I do a lot of /diy/ stuff on top of my table saw, it being the flattest and sturdiest surface I have. But even leaving a palm print on it tarnishes it.
Johnson paste wax - felt amazing to the touch, but barely any protection, tarnishing occurs within a few days and any moisture on the top would surely result in surface rust
I will not try a heavier oil or grease, because obviously despite being the best rust protectant, the surface has to be at least sort of clean to the touch. So basically, rust protection and 'feel' seem like inverse properties. Are there any substance that bucks this trend? Or perhaps, is there a good hard-coat that could be applied to bare cast iron to keep it dry to the touch, yet durable enough to work on and totally rust proofed?
The setup requires a timer to complete the circuit and turn on the enlarger lamp. I don't have a timer. The timer plugs into the back of the power supply.
I only took a basic electrical engineering course in college so I don't know much about this. I'd like to avoid having to buy a timer. Could I use a spare electrical cord, plug it in the back of the power supply, and cut the other end off, connecting the positive and negative wires?
>>927489 OH wow guy, I just bought a Zenith BnW enlarger for my girlfriend. She wants to build a dark room so I'm hoping to surprize her. A late new year sort of present. However didn't get a timer with the unit. Its a simple little unit with a incandescent bulb in the top that just plugs in to a wall outlet. I figured id just make an Arduino controlled timer with a relay switch and a timer. But I haven't given it much thought yet. I kinda figured i'd use a couple of buttons one prolongs exposures...

>>927323 we need to get some more information from you what do you want to remove what is it made of what is the shirt made of how did it happen why do you want it removed literally fucking any information at all
Hello /diy/ I came across 19 omron relays. Some info 5a 240 vac 5a 28 vdc Coil : 110/120 vacation Are they worth anything if I was to sell them on ebay, and more importantly what are some things I could make with them?
>>927144 Unless you have a hundred each of them it's not worth the bother, you'll get a few bucks apiece for them, and by the time you pay Ebay their jew money you'll have nothing or have lost money. Just throw 'em in your junk drawer in case you need them.
i also have a few semiconductors, correct me if im wrong; they will allow power to flow through them if they hit the right temp? so i could say put it in a room with a heater and have something turn on or off depending on how hot i get the room? (my dumb downed comprehensions)
>>926047 The patio looks like a pretty dark corner. The dark color of the wood adds to that. You might want to change that. Also the column, floor and everything else looks dirty. Clean that and/or buy new patio furniture. Add plants or grow spices or stuff.
You can not DIY a laser with that level of precision. You could easily make one that burns off small patches though. If you wanted. For some reason. That wasn't insane. I mean, you can do self surgery with a pocket knife too, doesn't mean it's a good idea.
You can not target the DNA without damaging the rest of the cell. That requires higher wavelengths then a laser produces, like Xrays or Gamma rays.
