### Depth of the thread cut by a tap?

If I was to drill a deeper hole, I buy a longer drill bit of the intended diameter.  I am sure the same thing apply to the taps as well.  However, in their specifications, I do not see anything about how deep a cut they would make.  So, my question is, what should I be looking if I need to make a deeper thread than than the tap I already have?  I mean is there a number which would say that this tap goes only one inch deep and so on? Thanks.

### What could I use for a depth sensor in a SeaPerch ROV? Answered

I am in the process of building a SeaPerch ROV, and I want to add a few sensors with an Arduino. I have the other ones figured out, but I can't figure out what I could use for a depth sensor. I've thought about using a pressure sensor and calibrating it to give me a rough estimate of how deep it is, but I don't think that'll work too well. So if someone has some ideas for what I could do for this, that would be quite helpful. Thanks.

### Which Direction Does She Spin?

Check out the optical illusion below. Since the figure is totally black, there's no depth- you can see her spinning either clockwise or counter-clockwise. Which way do you see it first? Try reversing the spin direction- moving your finger in a circular motion at the rate of rotation can help you reset. How easy is do you find it to swap perspective? Does it make your brain hurt?

### Pressure, vacuums, and the on earth equivalent?

One atm is equivalent to about 14.7 psi.  Does that mean that if one was in a perfect vacuum a vessel sporting 1 atm would need only hold the pressure of 14.7 psi?  It seems to me that in space (not a perfect vacuum) a craft would only need to hold maybe 12 psi (of course when messing with human life I would definitely allow for 150 to 200% tolerance, but in the end 24 psi still isn't very much is it.  Is there more to it than this, or are all those quotes about how hard it is to deal with a vacuum and how things must be super strong a little over blown.  Going just 11 meters under water exposes you to a little over double air pressure at sea level.  Someone in just a diving suit has been to over 60 times atmosphere and the deepest submarine dive I could find was 1083 atm at around 11000 m.  It just seems to make holding out a vacuum a little overrated.

Pretty sure that a "depth of cut" setting is not a standard feature on a jigsaw! the angle of the cut ya, even the angle of the blade front to to back, but not the depth.

### Maximum thickness versus depth of metal welded? Answered

When you say thickness of metal up to 1/4" or 5/16" is that the depth of metal that the weld penetrates? So if I were welding two pieces of 1/4" angle iron (like making a corner) then the weld should hold fine. But what if I were welding 1/4" angle to a base of say 1/2" thick (both pieces being mild steel) would this weld hold since one piece is 1/4" and the larger piece is 1/2"? Great course so far by the way!

### How do I turn AGC (auto gain control) off on a webcam?

I want to make a DIY 35mm style digital camera from scratch out of a webcam, a Depth of Field adaptor, and a micro-pc. The only problem is that DOF adapters are very dark, and they cause a webcam to use it's auto gain control (this causes little multi-coloured patches in the dark areas known as "noise"). It's a great idea for a video chat in the dark but nothing professional. I know that all the webcams I've researched can't have gain turned off via a PC, so surely I can detach something from the PCB of the webcam (I assume there is some sort of gain module inside it). Please Obi-wan Kenobi, you're my only hope. What can I do to turn the gain off?
