Multimeter

Could you go into a little more detail please?

[QUOTE=~ZOMG;44764307]Could you go into a little more detail please?[/QUOTE] I=V/R Set the pot to one end, measure the current when a known voltage is applied, set pot to other end and repeat. SHould give you an idea of the resistance range. Assuming this pot is fairly low current.

Or just hook your multimeter up to it, set to ohms, and test it that way with 100% less math.

Assuming this pot is fairly low current.[/QUOTE] Sorry, I should have been more clear. The potentiometer is so shagged that if its resistance is anything but 0, the signal is completely ruined. The maximum resistance is something like 17 ohms, but I'm fairly sure that's because it's ruined. Is there a way to work out what resistor I would need based off the current and voltage going into it?

I'd like to learn a bit of leatherworking, partly because it's always interested me and partly because I'd like to combine it with maille to make some mad sick armlets and/or guitar straps. Anyway, I read the first two articles [url=http://leathercraft-projects.com/a-compendium-of-leatherworking-tutorials/]here[/url] so I suppose I'm more or less familiar with the tools, but I'd like to know more about what type of leather to buy first, to practice on. For example, is [url=http://www.tandyleatherfactory.com/en-usd/home/department/leather/tooling-shoulders-bends-bellies/tooling-shoulders-bends-bellies.aspx]tooling leather[/url] the right category to browse? [editline]14th May 2014[/editline] Addendum: from what I gather, [url=http://www.tandyleatherfactory.com/en-usd/home/department/leather/tooling-shoulders-bends-bellies/9080-99.aspx]these[/url] would be good to learn on. Am I correct?

[QUOTE=garry;43322216]Yeah that's the kind of thing. Why can't they build them into the socket so it doesn't look any different to a normal one :([/QUOTE] I'm not sure if this has been covered in the rest of the thread or if you will even see this but: [url]http://www.screwfix.com/p/2g-13a-single-pole-switched-socket-chrome-with-black-insert/90734#[/url]

I made this at work the other day. I make a lot of different hammers and tools, but this one I'm keeping as one of my favorites. Since i work on a wooden coaster, there's a lot of stuff that you sometimes can't reach, so I made this to solve that the other day. Got three things I've been wanting to get to for a long time. It's a 3lb sledge... with a 5 foot handle. I call it the kentucky longsledge. [URL=http://s43.photobucket.com/user/serj22/media/IMG_20140515_112412_zpscb2d9f62.jpg.html][IMG]http://i43.photobucket.com/albums/e356/serj22/IMG_20140515_112412_zpscb2d9f62.jpg[/IMG][/URL] It was a quick 20 minute thing just to get some stuff done. Nothing pretty.

It actually looks pretty good.

For a second, that perspective fucked my brain up

I'm about to embark on a journey no man should have to travel alone... I'm going to be fixing up this. [t]http://imgur.com/OEKKqlM.jpg[/t] That, for those who are unaware, is a 195X-196X Summit Plastics Eames Armchair by the Herman Miller furniture company. Specifically, it's an elephant grey shell with orange nagahyde, sitting on a zinc-coated steel H-Lounge base. LAX combination. It's rare. It's old. It doesn't have the black rubber edging that was common on these shells post-1965 or so, for reasons unknown. However, all the upholstery is original with tags, and there's no evidence of that edging having ever been there, so I'm assuming this is purposely lacking it. I'm going to pick up some supplies tomorrow. I plan on restitching the seams with a thicker-gauge nylon thread, and I'm debating on adding Loctite Vinyl Glue inside the seams to prevent future rips or tears. After that, I'm going to clean it, since the nagahyde is quite dingy (Dishsoap and hot water is recommended, followed by automotive vinyl polish.) It didn't come with base bolts. Apparently, the previous owners never had them. I've managed to figure out that they're 1/4"-20 x 1/2" screws, though, which can be found at most big box stores. I'll go pick up some tomorrow. After that, I need to figure out the best way to clean the zinc-coated base. I'm guessing soapy water would work there, but I'm not sure on that. If you've got any advice, let me know. I really don't want to damage the zinc finish, but I want to clean off the fifty-odd years of scum and get it shiny again.

[QUOTE=DeVotchKa;44829755]It actually looks pretty good.[/QUOTE] Thanks. I made the cut and shape based off of a random skilsaw cut. I really had no plan other than to taper it down and make a handle in the back to attach to my climbing harness. Glad it at least looks ok

I finally got the chance to work on my old longboard today [t]https://dl.dropboxusercontent.com/u/62766551/P5200524.jpg[/t] It got run over by a 4WD just over 2 years ago and I've been meaning to get it back to working order. Back when it first happened I just planned to lop the end off and replace the tape, but over such a long time laying dormant I came up with a few ideas. Here's a shot from shortly after it originally died: [t]https://dl.dropboxusercontent.com/u/62766551/476328_3249687273734_1394546469_o.jpg[/t]

So, I'm interested in buying an Arduino Uno, and I was looking around, and I found the following: [url=http://www.ebay.co.uk/itm/Official-Arduino-UNO-Rev3-R3-328-ATMEGA328P-Board-with-Free-USB-Cable-/160842804534?pt=UK_Computing_Other_Computing_Networking&hash=item2572fa6d36]An official distrubor selling it for £19[/url] [url=http://www.ebay.co.uk/itm/UNO-R3-2012-Development-Board-MEGA328P-ATMEGA16U2-With-USB-Cable-For-Arduino-/231071693106?pt=UK_Computing_Other_Computing_Networking&hash=item35ccf23932]And this one, selling it for £7.[/url] What's the deal? Is the cheap one a fake?

Is the pope catholic? Of course it's fake. [QUOTE]Arduino-compatible board [/QUOTE]

[QUOTE=Leestons;44859412]Is the pope catholic? Of course it's fake.[/QUOTE] That's not necessarily bad though.

Even though it's fake, it's most likely gonna be functionally identical.

Here's something that i've been meaning to show off in here for a while. It's a so called woodgas stove. [img]http://i.imgur.com/R4CtZZwl.jpg[/img] It's a retardedly simple construction really but with a rather nifty design that makes it very fuel efficient! [img]http://i.imgur.com/paw4bZ2l.jpg[/img] Made from two tin cans punched together so that the smaller one sits snuggly inside the other. [img]http://i.imgur.com/901B07Bl.jpg[/img] the many holes serve as air vents to supply the fire (which burns inside the small can) with air. However the top row of holes you see serve a different purpose! As the wood burns it produces heat and smoke. the heat warms up the air between the two cans and this makes a vacuum that sucks in air from the outside and also sucks the smoke downwards. The smoke and air is mixed up and ignites together when it comes out through the top row of holes. The result is fucking awesome. as long as the air supply is good and it burns warm enough there's literary no smoke at all since it's all combusted. one time i got blue flames shooting out through those holes. Moving on to this thing. [img]http://i.imgur.com/H3cq67Tl.jpg[/img] This is a pot stand. or a tripod or whatever. i basically just took a bunch of metal rods and bent them into shape and had a guy from work weld the pieces together. [img]http://i.imgur.com/zC5AeSvl.jpg[/img] the point of this thing is to elevate the pots from the stove so that the fire doesn't suffocate. from what i've seen, in tutorials and other peoples designs, you could just take a second very low tin can, punch it full of holes and put it on top of the stove. i tried that but the fire would die anyway and the can would get too badly burned and warped. So a tripod sprung into my mind. it also serves a pretty important purpose that the tin can would not have been able to help with. [img]http://i.imgur.com/xfuQkVKl.jpg[/img] Stability! As you can see in the picture above the tripod is driven into the dirt to fix everything except the pot into place. so there's no chance of me accidentally nudging the thing and send hot embers all over the place. I guess that's all i have to say about the woodgas stove. really nifty little thing. for a very very tiny amount of wood i got a litre of water to boil. it took atleast half an hour sure but i won't really need to boil a whole litre for just myself. frying a hot dog took less than 1 minute!

[QUOTE=chipset;44866599]Even though it's fake, it's most likely gonna be functionally identical.[/QUOTE] So, are there any disadvantages? Because I'm interested, but I'm also a poor student, and the official Arduino price is kind of putting me off.

[QUOTE=~ZOMG;44868933]So, are there any disadvantages? Because I'm interested, but I'm also a poor student, and the official Arduino price is kind of putting me off.[/QUOTE] It's not guaranteed to work/ last as long/function as intended, but the chances are it's pretty much identical.

[QUOTE=chaz13;44869286]It's not guaranteed to work/ last as long/function as intended, but the chances are it's pretty much identical.[/QUOTE] Is that likely? That it won't be nearly as good of quality.

[QUOTE=~ZOMG;44869961]Is that likely? That it won't be nearly as good of quality.[/QUOTE] Of course. You get what you pay for with electronics. They don't just decide not to sell it at a profit, it's usually a combination of cutting corners, copy work and grey market components.

[QUOTE=metallics;44871045]Of course. You get what you pay for with electronics.

I wasn't even aware there was a lot of wriggle room for quality when it came to things like this. Would it be so bad that it would be better to just go for an official one, just for some tinkering and such?

The odds of it failing earlier are probably negligible at that price. [editline]21st May 2014[/editline] Or rather, the amount you lose if it does fail earlier is negligible, you arent likely to be using it for something safety critical right?

I'll probably pick one up, and make a post saying whether or not it's outright awful straight out the box. Cheers for all your help, I really appreciate it!

Exhaust fell apart right as I got home today [img_thumb]http://i.imgur.com/IFQ7rBv.jpg[/img_thumb] Ingredients: * 3 Dremel cut-off wheels * 1 15oz Can Black Beans * 4 Hose Clamps * 1 Beer Prep Time: 1 Hour Cook Time: 30 Minutes Directions: 1) Remove old clamp with cut-off wheels, pliers, and cursing. 2) Cut both ends off can and slice lengthwise 3) Carefully attach can with hose clamps in place of old clamp. 4) Drink beer [img_thumb]http://i.imgur.com/ddvyBQY.jpg[/img_thumb]

Made a small 'pocket' knife, as I finally retired my worn out folding knife. Only took a couple hours to make. I wear these TruSpec pants all the time which have these two knife pockets, so I made a leather sheath that fits snugly in the right pocket. Hence 'pocket' knife.

So I ended up getting that leather and made some stuff. This was a super quick bracelet that I made after playing around with maille rings and scrap leather (that piece in the background); you can also see the second bracelet in progress next to the scrap piece. [t]http://i.imgur.com/MgGoqZj.jpg[/t] [t]http://i.imgur.com/prkoTSt.jpg[/t] While this is the main reason why I got leather in the first place. I might make more and sell them for $$$money$$$ but I also want to make a guitar strap or something along those lines. We'll see.

Does anybody here know anything about bending plywood? I know the couple over at onefortythree's figured it out, but I don't have quite as stocked a shop as they do. (One day, but that day is not today.)
