  1. I've heard size issues come with age.... How is space engineers? Last time I played multiplayer I got motion sick from the server rubber banding me around.
  2. Lol MH6 I figured you would be using it for flying choppers in games like Arma3. As a glasses wearer i'm less inclined to pull the trigger until more time has passed and the fit and finish is a little more refined on these things.
  3. God I hated those things, I actually fell off my bike one day and the pedal took a nice chunk out of my knee.
  4. https://www.bistudio.com/blog/bohemia-interactive-latest-acquisition-t72-main-battle-tank
  5. Dont see the server
  6. Looks interesting but im not dropping $40 on an alpha.
  7. A similar form of that wheel has been around for atleast 10 years, I think cost is the only limiting factor atm.
  8. Just an FYI its set to the Navezgane map.
  9. Does not show up on the server list and nothing happens when I manually put it in at the bottom.... edit. Got it to attempt to connect but it always fails to connect
  10. Sadly 7.62 x 39 prices have slowly risen over the years, it used to be 1000 rounds for $120ish. Ive wanted to add an AR to my collection but I need to pay off a few things before I can start increasing my collection again....
  11. Less then 37% of the total US power output is from coal and that number drops every year due to conversions and retirements. In the last few years Obama and his friends have pretty much killed the coal industry in the US. (the sister company to the one I work for does electric propulsion for mining, mainly coal and they have been hit hard.) All power generation will be inefficient.. Do you really think your car is actually efficient? Maybe compared to other cars but not by the standard of the amount of energy used and produced.
  12. Gonna call BS on the 1.1MegaWatt Hours. First you would need 492x 700A 3.2V cells, a whopping 10627kg and it would require at least 6.3 cubic METERS! Based on range i'm thinking its more like 110KiloWatt Hours.
  13. Just an few points since I live in the electric propulsion industry. Charging an electric car on the "Grid" is far more efficient then any gas car when it comes to emissions. The power generation for the "Grid" is far more efficient. The only option for electric cars right now is Lithium. Its highly toxic to dump. But is also recyclable, the number of places that will recycle are increasing also. We actually face a more dangerous dumping problem of all those little phone batteries then from electric cars. Current storage tech is just not up to par when it comes to the amount of mass needed for the batteries. The cost is also prohibitive. Unless gas hits $10 a Gallon you wont see a surge in electric cars. And that surge will be limited by the availability of the small electric car production chain.
  14. Going to need to add another 20A breaker to power the monster I will need to play it......
  15. That is not the best tool for this.... Since it does not deal with capacitors. First its not the total storage(in watts for this case) but how fast you can dish it out and how long its actually needed. Lets do some math first, lets go with a starter that needs 300A(actually pretty high for a small car) to start a car. That's 300A x 12V = 3600Watts, but that's 3600 watts in an hour. So divide that by 3600 seconds in an hour you get 1 watt per second. If it takes 3 seconds to start the car then you only consume 3 watts from the battery or capacitor. Now for the capacitor, lets go with the 350Farad/2.5V caps. Now the math for this is different and it gives you watt per second. And capacitors in series dont stack like batteries would, instead they are added the same way resistors are in parallel. So for 6 series capacitors at 350Farad and 2.5V you end up with a 58.334Farad capacitor good for 15V. 3600 Joules = 1 watt/hour energy(joules) = 1/2 * c * v^2 0.5 * 58.334 * 15^2 = 6562.575 watt/seconds 6562.575 / 3600 = 1.823watt/hour , that damn napkin was drunk I tell ya! That's a little short for 3 seconds, but if you need 300A to start a small car then you need a new starter/engine anyway. One thing to remember is that with a Lead acid battery, pulling 300Ahour will drain the battery exponentially faster then a 20Ahour rate or 100Ahour for that matter. The capacitors wont care since there internal resistance is massively smaller then the battery. But you waste more energy charging capacitors vs batteries. Edit, just found this nice little calculator. http://www.calctool.org/CALC/eng/electronics/capacitor_energy
  16. Speaking of cramming batteries..... I should have this monster running in a few months
  17. Actually you can, its more to do with it not being a practical thing to do. Just using the CCA you gave, you need roughly 1 watt per second at 300A to start a car. Those small caps can hold over 30 watts of usable power before the voltage goes to low. The small blue caps he showed are actually capable of a short circuit discharge in the 1000A range. That larger bank he showed would probably work better for most people, but regardless of which caps are used some form of charging/maintaining would be required. Like a small solar panel.
  18. EE rant system activated. That looks cool..... Sadly I went to school for electronics so its actually not so cool...... Pros. Will outlast a normal car battery (provided he adds atleast 1 more cap in series since they are rated for 15V total and a car can actually exceed that in some cases) If he removes the stupid sock he put on them later in the video they will also last much longer..... Much lower Internal Series Resistance vs Lead acid batteries (meaning more instantaneous power... also bad in some ways) Cons. Most caps are rated at 80C for a few thousand hours.... Most cars can get hotter then that under the hood, way to go sock man..... Based on bar napkin math you will get about the same amount of power as a small 12V 4A SLA battery, but you can get it all almost instantly. So don't forget to turn your clock off........ Since they have really low ISR you can damage a normal battery charger trying to charge them, damage your alternator trying to charge them, damage some poor sods battery trying to jump start one and last but not least burn out your starter much faster then with a normal car battery along with wearing it out alot faster every time you start the car. You can do much the same thing with a 3Cell lipo battery out of an electric car, you can also cause them to burst into flames if you leave them connected to your car to long while it is running....... EE rant system off. Its a cool idea and I may play with it for my electric gocart but for the average consumer it will cause more issues then it will solve.
  19. The circuit boards i'm used to testing receive 24V dc and use an onboard switching power supply to isolate with a transformer from the external supply, it then uses a few smaller switching supplies with inductors to give the voltages we need. And the trains whose electric motors are powered by our inverters keep running on the tracks. Since I seriously doubt they are using isolated power supplies, so they have no need for transformers... But inductors for switching power supply's make sense. Its possible that the vendors with issues bought a coil that fit the inductance but maybe has a different rated frequency due to a different core material. Or possibly a poor quality part that has less then optimal expected inductance.
  20. As someone who tests and evaluates circuit boards for a living I call BS. Its most likely a resonant frequency/bad filtering or a poorly chosen inductance that does not work well with the supply it is being used on.
  21. Game runs fine, controls and menu's are about as retarded as the characters......
  22. The number one enemy to computers is between the chain and keyboard......
