/diy/, I've never had a black eye. I've had many different bruises in my life, but never in or around the eye area. I want a black eye, /diy/. How can I give myself one without damaging my eyes? I like my eyes and seeing stuff with them, but I guess I also have a thing for self-harming to an extent, and I think bruises look nice. How can I damage the tissue around my eye without harming the eye itself?

So I got this 32" LCD TV from a friend, it doesn't work and isnt worth fixing. What kind of stuff can I make with it? I plan to use the backlight to make a tracing table, but what else? Make a picture frame with the screen bezel?

Damn it, h. I went to the trouble of typing all this out: http://www.jbweld.com/faqs/ >Is J-B Weld toxic? >No. When fully cured, J-B Weld is non-toxic. However, we do not recommend consuming the product. I can't find anything similar for the E6000 stuff. I think both products are toxic until cured, but as I said I can only find that JBWeld is non-toxic when cured. I suspect you are referring to the curing fumes as to their toxicity? I'm not sure there's a good substitute that will be non-toxic during the curing phase. HOWEVER, I do have a recommendation. Build yourself a box with a glass/plexiglass/plastic wrap front that has a place at the bottom to comfortably get your hands into it. On the top or back-top section of the box make a hole and attach one of those silver dry vent hoses to it. On the other end of the dryer vent attach a vent fan (bathroom vent fan, salvaged microwave vent fan, etc). Build a thing there to hold the vent hose and the vent fan so that you can open a window and set the vent fan unit in the window so it blocks all outside air and keeps your fan in place. Then when you need to do cementing you can do it inside this vent box. Turn on the fan and all the fumes go outside. Since the fan is at the window and not in the box there's no fumes at all being pushed out of the box. Even if there was a leak in the vent hose the hole will suck air in and keep the fumes in it until they get sucked out the window. Install a light in the box if you need to. Let your items cure fully in there. I use a similar box for all my toxic fume-producing DIY projects; from spot welding, soldering, to painting. I can light a match in it and not once smell sulfur fumes. I use a microwave vent fan in mine.

This is my lawn mower. It randomly cuts out while mowing. It will usually work for 5-10 mins before cutting out. This is a video of what it does once it starts cutting out http://www.youtube.com/watch?v=brFcXrHo65A . Any ideas on what it could be?

hi diy, i need some help more or less spontaneously is decided to start a new project. a while ago i ordered a dmg connection cable to use it for the lsdj keyboard mod. as is described here http://the.fontvir.us/b10g/?id=126 so in the last half hour, i deisolated the cables and wired them together. the ps/2 cable coloring was different so i had to look its assignemt up. there is a table in the picture refering to its assignment and how i connected the cables. its all done rather quick and dirty, to check if it works at all. which it does not and why i'm writing this post. before i take it apart again. did i make mistakes with the wiring?

Home made desulfator

0 more posts in this thread. [Missing image file: desulfatorsch[1].jpg]
I recently built the desulfator in the attached pic, from Frontier springs dot com. I used all of the correct components. Built the circuit exactly as it is shown (except for the mosfet, it is shown upside down, and this is even discussed on the website). And the damn thing doesn't work. I'm supposed to get a high voltage output across C6 (starts out high with a highly sulfated battery, then decreases as the battery desulfates) but I only get my battery voltage out (12.5v). I'm supposed to get 1KHz out on pin 3 of the 555, but I get 8KHz. I'm stumped, frustrated and frankly a bit pissed off. I've found videos on youtube of people who have built this, and theirs works. Has anyone here built this? If so, any suggestions, hints, ideas, etc??

Hello everyone So im currently learning the trade of machining. Taking a class monday-friday 8 hours a day lasts for 20 weeks. Im in my 9th week now and I have learned a lot. Im learning how to operate manual lathes and mills and how to program and run cnc mills and lathes. Ive made a met tenderizer, plumb bob, fly cutter, die stock holder, and miscellaneous things that were just to prove a concept. This here is a little puzzle i made today on the manual engine lather. I made it out of brass. I made each half individually. I made the threads on the internal post with standard tap and die methods. Once i made the post and internal thread i assembled each side together and single point threaded the outside threads so when you put each side together the seam would disappear. I made the brass nut out of a piece of round stock turned it to size and made the threads on the lathe. I then put it in an indexer and made the hex shape on the mill. You can pretty much see where my skill level is with this piece (rudimentary skill level at best). So i have a lot of time in class and im ahead of schedule and the teacher is pretty lax about personal projects like the one i made here. So do any of you have some ideas on what i should attempt to make. Im in a fully stocked machine shop so pretty much anything is possible.

Hi, I'm trying to clean my monitor and followed this http://pcsupport.about.com/od/maintenance/ht/cleanflatscreen.htm tutorial, but I'm not sure whether the vinegar I have is right. I have 'Tafelessig' (table vinegar) made of 5% brandy, pic is not the exact one I have but very similar; the tutorial says to use white vinegar though Is that the same thing or is this stuff for food only? Or can I also use this?

Hey /diy/ quick question. My car has an exhaust leak and I want to fix it myself. I was thinking of cutting a piece of curved aluminum and then using JB weld to fix it over the leak. Is this a decent fix? I really don't want to pay a mechanic to fix it.

I'm working on a viking age costume, and after some googling I came across sources for hand-woven embroideries made out of metal threads, called "posaments". The problem is that I can't find a single guide on how to make this myself. Can you guys help me? Pic related.

Stepper motors

4 more posts in this thread. [Missing image file: ST4118.jpg]
I'm currently working on an early project and I wonder about feasibility. Setup: Stepper motor (type not sure about), one gear attached (weight 10g), turning another gear (10g), ratio 1:1, turning a sleeve bearing with minimal friction. I want that stepper motor to turn something mounted on an axis from 0° to 63° within 0.03s (+/- 0.015s) via gears (1:1..2:1 max gear ratio, that means either direct or slower). Within this angle I want to have at least (can always be more) a dozen steps so I can adjust the specific angle. Many stepper motors have steps of 1.8° --> 63°/1.8°=35, so at least this will work out. The friction of my simple gear will likely be higher than the friction of what I am moving. Both are rather negligible I'd say. Something similar to a proper sleeve bearing, maybe. So what I worry about is inertia, unfortunately I suck at this part of physics and stepper motor electronics. The gears have a weight of ~20g and are attached with proper ball bearings. The application needs to be mobile and compact. That means powered from a couple of eneloops and of 40mm width or lowered. I can provide up to 35V@4A via a switching amp if needed (although don't expect it to be ripple free at this much current). Question: Will a stepper motor be able to accelerate two 10g gears (one attached to the motor, one to my axis mounted piece) to 35(?) 1.8° steps (or 63° with at least 12 steps) within 0.03..0.045s? What kind of stepper motor should I be looking for? From what I understand about steppers so far is that they need a ramp to accelerate, but I'm not sure if I'm already within the need for such a thing, or if it's even doable. Anyone can help me out?

Medieval armours

6 more posts in this thread. [Missing image file: _IGP0021.jpg]
Hey /diy/ , newb here. So i've been inspired by medieval Assassins and Assassins creed. I want to make leather armour, that's unique. But i have no idea how to deal with leather, nor metal. I don't want to buy already made armour, because i wont be able to fix it later if i ruin it somehow. Please /diy/, give me a start. ( Not full leather, since i am acrobatic and "sneaky" type. I could also put in a design )
