  1. Earlier you mentioned 100 N design. Was the load cell underrated or just faulty? Also, can we have some pics, please?
  2. That is by far the worst battery leak damage I've seen. That being said, just yesterday I received a flashlight of my own - BLF A6. I'm quite amazed by how much light it can put out, even with the low charge battery. It takes a single 18650, for which I have a charger I bought recently in anticipation of buying a flashlight. I've never used it and it's been sitting on my desk for a while, but now the opportunity presented itself, and I popped the battery inside it and flipped out the mains plug (the horrible thing on a hinge) and tried plugging it in the socket, only to realize that it's not going to happen. All the mains sockets over here are recessed and the prongs of the plug on the charger don't reach deep enough. I already have a new charger in the mail (this one is USB, so it should be ok), but I don't expect it for another two or three weeks.
  3. Christmas doesn't enter my home until the evening of 24th, and even that against my taste. The tree also gets booted on the 6th of January, back to the cardboard box it came from, somewhere in deep reaches of the basement, to my endless satisfaction (well, 11 months of it anyway). Unfortunately, my work is heavily dependent on the income we get during December, closely related to ho ho ho stuff, so I suffer. Thankfully, we recently scored a good commission work, unrelated to Christmas, and I happen to be working almost exclusively on that, so I am somewhat spared.
  4. You're forgetting that we're not talking about recreational scuba diving, or even professional technical diving. We're talking about living in a high pressure oxygen rich atmosphere.
  5. It most certainly is. http://archive.rubicon-foundation.org/xmlui/bitstream/handle/123456789/6310/SPUMS_V26N3_13.pdf?sequence=1 TABLE 1 NOAA OXYGEN LIMITS FOR SINGLE EXPOSURES PO2 Time 0.6 bar 720 minutes 0.7 bar 570 minutes 0.8 bar 450 minutes 0.9 bar 360 minutes 1.0 bar 300 minutes 1.1 bar 240 minutes 1.2 bar 210 minutes 1.3 bar 180 minutes 1.4 bar 150 minutes 1.5 bar 120 minutes 1.6 bar 45 minutes Even at the depth of 20 m (3 bar total pressure, 0.6 bar partial oxygen pressure) you are already in the region of toxicity for prolonged exposure.
  6. You have to be careful regarding partial pressure of oxygen. At around 0,5 bar it starts to become toxic.
  7. I used FreeCAD for a short while. It's actually quite decent for the cost (free as the name might imply), however, I returned to SolidWorks (which is, of course not intended to be free), but is a beast and just works for everything I threw at it. I don't remember if anything particular was wrong with FreeCAD, it's just that SW is so much better. FreeCAD uses pretty much the same design philosophy as SolidWorks, which I find extremely intuitive. In contrast SketchUp (also free) is something I can't wrap my head around and find unusable. That being said, I've seen people making some impressive stuff in SketchUp. All three of these are actually 3D, but they have no issues with 2D.
  8. Why do you think there is, or should be any? ib4 42
  9. I consider a PC much more than just a gaming platform. For me it's a also a work tool. Furthermore, I don't own and never have owned a console. I just don't see the appeal or justification for the usually expensive purchase of a dedicated game thing. As for the questions of games taking advantage of modern hardware, games have always been a significant driving force in hardware development.
  10. There is also the energy needed to move around all the air to get access to that small fraction we're interested in. Thunderf00t did the calculation in his plastic from air video.
  11. Finally, once it gets obnoxiously loud, put a big fan in front of it, connected to the spinnamathingy, so a whole bunch of air goes around the engine making a sound barrier. I bet it would even make the whole thing better, sending ISP to 5 digit numbers.
  12. There have been a few launches since the start of the thread. Perhaps title change is in order?
  13. While I agree that 7 is better than 10 in some regards, I gave into the forced upgrade from 7 to 10 a couple of years ago and honestly don't mind it. Not going too deep into the whole spyware thing, other than to say there's that, but from usability standpoint, Win 10 is working perfectly fine for me. The what's-her-name search thing is disabled from day one and all the targeted ads stuff that you are asked about at the setup phase is turned off. What I would like to point out is that support for Win 7 is being terminated in mid January 2020 (a month and a half from now), so you are getting a new computer and installing a soon to be obsolete OS. Yes I know, options are limited and Linux is not for everybody (I honestly tried adopting Linux, but failed miserably. I consider myself above average when it comes to computers, but still failed to install network card drivers on Linux and that basically killed it for me. Things have probably changed since that time, but now I don't have time to revisit the attempt), but Win 7 is quickly going down the path of the Dodo.
  14. There are two clusters, but clusters are separated (one in Africa, one in Australia). In addition to those clusters, there are more dishes spread out around the clusters. More area does increase resolution, but with modern signal analysis methods, using multiple dishes is more cost effective way to achieve resolution. However, resolution alone is not enough. You also need the signal strength. That's where collecting area comes in. An analogy would be a digital zoom camera. With a powerful zoom lens you can see small details far away. That's resolution, but if it is dark you may have trouble seing anything. You could try cranking up ISO (gain) but at some point you are just introducing more noise. It's too dark for a good picture. Opening up the iris will let in more light and give you a better picture, but if you've already reached the largest aperture, you're kind of stuck. Your options are either to buy a new camera that has better low light performance (with radio telescopes this won't work since they are already cutting edge and there is littke room for improvement there) or you can use a bigger lens to catch more light (more surface area for radio signal gathering). Basically, the distance between antennas helps us see small things (resolution), while total collecting are helps us see the dark, faint objects (sensitivity). Again sniped by Bill.
