Sanding small flat surfaces so they stay flat

Hi, I'm trying to sand fairly small wooden objects that are about 1/2"x1" and sometimes a little larger. I often find that one side is thicker than the other or the corners are no longer perpendicular. I am trying various techniques, like taking a chunk of 2x4 and wrapping it sandpaper and then vice it to my workbench. Then I rub the object against the paper block. That is getting better results.  I've read that some people use spray-on adhesive to secure sheets of sandpaper to a granite top and that it is supposed to work well. There are a few instructables that explicitly talk about sanding and I've read many of them. They advocate a bunch of techniques. I'm wondering what other folks have had success with. Thanks, Andy

 Im interested in peoples feedback towards current flat-pack furniture or D.I.Y products. Problems and annoyances with current methods of putting together these products, problems with materials and fixings used etc. Any problems regarding requiring tools that aren't provided or instructions being awful? On the other hand, has anybody had a great experience putting together anything flatpack or D.IY? (Eg: bookshelves, bedside tables, stools, BBQs, anything requiring assembly really)? Any insight would be great!

UPDATED: Today I was totally GROSSED OUT....Plus pics, and progress !

The landlord came today to "fix the walls" again, like he did a few months ago, and again 3 days ago....but his helper told him this wasn't they started tearing the Bathroom and Bedroom wall (the adjoining wall) down.  The portion towards the outside wall of the building.....they found a pipe that was leaking....a big 9 or 10 inch iron pipe......guess what?   That is the drain from upstairs for the bathroom sink, the bath tub, and the TOILET.   For over 6 months now, we have had our bedroom wall deteriorating and being soaked by SEWAGE.... The helper told me in confidence that we are not the only ones he does this too.....grrrrrrrr. Pictures have been updated with ones I took...

Help wiring a laptop's LCD display?

Greetings all! I had the pleasure of demo-ing an HP Pavilion laptop computer for any and all scrappable parts today.  Fun enough in itself, but now come the real questions that I don't have the answers to.  What to do with many of the working pieces.  The LCD display, in particular.  Some information that may be useful here: HP Pavilion dv6227d Entertainment Notebook PC There are many tags on the display itself, but I think this is the manufacturer: AU Optronics B154EW04 V.2 I'm curious if anyone has done any projects involving displays such as this, and if so, what the application was, how it was wired, etc.  It's so light and thin, I'd just hate to see this thing go to waste or end up sitting in my parts bin.  Any help would be greatly appreciated!  Happy Holidays, ghost

Time & space: A dimensional discussion

Would anyone care to discuss the forth dimension of space? I have included a little Paint drawing I made. The "box" drawn as we would see a 3-D glass blox. and a 2-D world of Flatland. In this world, we demonstrate that the inability to turn their heads (left or right) prevents them from seeing the 3rd dimension directly, but that a shadow cast by the dimension, would be seen, either on the box itself or on the ground. A number of illustrations of how we might see a four dimensional cube are included. The last one is how it might appear if it was unfolded from itself. If this is indicative of reality, what conclusions might we draw from this?

THREE-DEE VIDEO from multiple lcd panels.

This morning I was watching television and thought to myself, "Wouldn't Good Morning America be so much interesting in three dimensions? This got me thinking, and I came to this idea: what would happen if you dissected a bunch of lcd monitors, removed the backlights, and stacked them. Then, you plug all of the screens into a processor that generates an image for each screen, and have a powerful backlight to illuminate these screens. I know that it is quite a stretch, but if one could work around issues such as the amount of heat produced and the cost of production, I think this could work. I think the best bet for input would be using RGB or CKMY on multiple panels, but I am not an expert in optics or any of that. So basically, this is an outline of what would need to happen, as far as I can tell: 1. A group of LCD panels that, when in a cascade formation and are fed sufficient data, produce a three-dimensional image 2. A bright backlight that is capable of illuminating said LCD group 3. A video processor capable of sending multiple signals to the screens that would produce a three dimensional image (as stated in point 1) 4. A cooling system to maintain component functionality 5. A benefactor or deep pockets 6. Lots of spare time If you have any ideas, please add them, I'd love to hear from the Instructables community.

Flat Wall Plug Adapter? (for DIY extension Cords)

There is an extension cord (3 wire) which has a flat wall connector - great for tight spaces.  I've bought some over the years (about $12 each at Amazon) - but want a supply of the plugs so I can make my own custom/length cords.  I looked at a few electric parts places but no luck.  Any ideas/sources for a less expensive flat plug adapter? One option  is to replacc the wall outlet with a recessed outlet - but that does not work for me. thanks

Make your own philips screwdriver?

If I want a flat screwdriver in an odd size, I can take a piece of metal, heat it, pound it flat on one end and file or grind to shape; something within reach of even the clumsiest blacksmith. Is there some trick I'm missing that allows similarly simple home construction of a philps-style screwdriver? Or are they part of a plot to allow only factories to make screwdrivers :-)

Screws with Round Washers

Do the round washers need to be used when screwing a flat screen TV to the base for tabletop viewing? The washers came with the screws in the small plastic bag. Where do the washers go? Do you screw them on the end of the screws after you have attached the base? Can you just leave them on the screw as they were in the package before you attach the base?

Cable Ties

At present, I live in a flat I need to connect the indoor tv aerial in the kitchen to a set in the bedroom. This involves leading the cable around doors and possibly across the ceiling, to get to the opposing wall. Under normal circumstance, I could use cable ties with pins, but making holes is not allowed in the flat. I have been told that adhesive cable ties must help, but they appear very difficult to remove, and might leave stains. Any suggestions

Sensor to eventually measure weight ( up to 250 lbs)

Hi everyone, I am stuck trying to find a method or sensor to do what I want. Basically, I am trying to make a cheap flat weight scale- light weight and portable; thinner than using load cell sensors. I was hoping for a flat compression fabric or piezo resistive pressure sensor, but have not found what I was looking for. Does something like this exist?

Just HOW contraversial is this really? (Also: The Dunkis's Flat knex pistol review.)

I know this subject has been brought up before, but I'm the first one to actually have video documentation on this topic to my knowledge:  While I'm at it I might as well review TD's Flat knex pistol because I don't feel like making a separate topic for that: Design- 7/10.  It succeeds at being compact and flat but this results in some tradeoffs, such as a tiny handle.  Bullet lock does not work too well, the ammo falls off given a good shaking. Range- 6/10.  About 25 feet with oodammo, with 2 #64's.  Any more bands, and I have problems pulling the trigger.  I'm gonna go easy on this rating because it's a compact gun for showing off. Comfort- 7/10.  Sure the handle is flat, but it's also tiny and pretty hard to grip if you have larger hands.  Also the pin tends to hit my hand a bit if I'm not careful due to this. Innovation- 8/10. It's the first truly flat knex gun, but it also sacrifices functionality. Trigger- 8/10.  It blocks near the back of the barrel, but the part you pull breaks easily with more than 2 bands.  It's comfortable though and the spacers don't fall off. Overall- 7/10.  It's a novelty show-off but nothing too powerful.  Great for stealth if you ever needed to hide it.

Anyone know supply voltage for a Microtek ScanMaker 3600 flat-bed scanner?

. I just rescued a Microtek ScanMaker 3600 flat-bed scanner from the curb and can't figure what kind of power it takes. Nothing on the scanner case and the web pages at Microtek just say "wall adapter" without any specs. Didn't find a SM3600 fan site, just reviews that mention adapter as being an in-the-box item. Anyone know volts, AC or DC, and polarity? . There was a slight drizzle going on when I rescued the scanner. I've got the case open and I dried what few drops I could get to with paper towels. Is there anything in a scanner that will quit working/burn up if it gets wet or can I safely power it up once it dries out for a day or two? . I don't really need a scanner, but I've read on here that the cold-cathode thingies are fun to play with. :) . TIA

ideas needed for a horrible bathroom

I recently rented a new flat which has a small green bathroom. The tiles look horrible (green with brown floral ornaments - 60's style) and cover the whole walls till up to the ceiling. The room also has a green bathtub. Now I need some ideas to make this room usable and not a constant pain to eyes. Please remember that this is a rented flat where I cannot simply tear down walls. It must be removable after I move out again. I do hope this is the right forum to ask this.

Getting rid of a Coke Can's Curve?

In my quest of making use of beverage cans, I have come to one of the many points where I don't know what to do. As we all know, Coke cans are cylindrical. For this particular project of mine, I'm going to cut the top and bottom of the can off, and then slice the can vertically to create one long sheet. I need this sheet to be flat, but the curve is very resistant against my attempts to get rid of it. I've tried putting the sheet under a large dictionary and waiting a day or so, but to no avail. Does anyone know a way to fix this? Even if it isn't perfectly flat, it'd be alright. Thanks!

Mount a Dell ST2420L Flat-Panel Monitor on 2405FPW Base?

Hi Everybody.  I just bought a Dell ST2420L flat-panel monitor to replace my old 2405FPW.  It's a better monitor, but its base is terrible.  The old monitor's base could be raised and lowered by several inches, the screen could be rotated 90 degrees, and it tilted farther.  The new base isn't adjustable vertically, won't rotate, and tilts only a few degrees.  I was hoping I could mount the new monitor on the old base, but the mounting hardware is all different.  The attached pictures show (1) the 2405's base with mounting bracket removed, (2) the 2405's mounting bracket, which bolts onto the base, (3) the place on the back of the monitor into which the mounting bracket slots, and (4) how the ST2420L connects to its stand (I'd rather not take mine apart to photograph, but I'll do it if anybody who wants to help needs to see the hardware more clearly). I wonder if anybody has successfully adapted the base of a 2405FPW to mount an ST2420L or similar, recent monitor, or anything similar?  Or would be interested in taking on the project?  Thanks for any help or ideas. Regards, Jim Crutchfield Long Island City, NY

Innovative solar powered radiator - will it work?

Ok, so i live in a rented flat (apartment) in London UK. Its a small flat but its old and doesn't have a gas heating system so i'm stuck using expensive electricity especially as the windows are single glazed and winter is on the way! Brrrrr! I desperately need a cheap and effective heatsource Now I know solar water heaters can be suprisingly effective even in the cold and that got me thinking. I have a south facing garden. Couldn't I use the sun to heat the flat? Specifically, I was thinking, can I use a solar water heater to heat an insulated water tank, then use the tank to heat a radiator after dark? (See diagram below) Bear in mind in temperature during the day at the moment is 11 degrees. Will enough heat be generated to make the system viable? I.e. will the water heat the tank hot enough during the day to keep the room warmish for a evening? Other pressing questions: Do i need a commercial panel or will an instructables model work? Oil filled radiator or water filled? Will it auto-siphon or will i need a pump? cheers a million guys and gals!!!

Touch Sensitive counter project question

Hi everyone, Great to be part of this community. I am trying to make a touch sensitive counter, the sensor has to be as flat as possible, something like a thick cardboard, or I can put a flat sensor in between two sheets. It needs to handle about 10-20lbs of weight. It will go under fabric like carpet, so it cannot be super sensitive, clickable is fine. It will be connected to a very simple 1 or 2 digit counter. Any suggestions? PS: Eventually I'd like to upgrade this with a system that can instruct something else, for example 5 counters, display etc. Or be able to use bluetooth or wifi or arduino, and be able to count back. For example input 10 and it will count 1/10, 2/10, 3/10, etc..
