Hot damn! salt much? I feel like we both need to calm down and watch this video instead of turning the forums into youtube comment section: That being said, I still stand by the point I said, specially given the lack of concrete evidence that you have provided. Either way, on Monday I'll borrow some equipment from my Uni labs and perform measurements with a remote sense feature to eliminate the small resistance in the wires. I will use a clamp meter too if I can and we can them compare concrete results. Cheers!

Ok Im back (the seafood was absolutely awesome BTW). HAHAHA it really cracked me up. Almost reminds me of the YouTube comment section. For your peace of mind, here are my meters: And here is why I say that that the shunt resistor in the mA range of a meter is only a couple of ohms: I have been doing electronics for the last 7 years of my life, 2 of my uncles (who have masters degrees in electrical telecommunications engineering), as well as my professor of electric circuits (with a PH.D in some digital electronics design subject) have taught me that the resistance

<sarcasm> sure I'm just pulling all of this out of my ass to troll people </sarcasm> Ill be back in a couple of hours, then we'll keen on discussing.

I just went out to eat, if you give me a couple of hours I can provide you with a detailed explanation and calculations. In a nutshell, at full brightness a single well fed led will consume a little under 60 mA. (Big emphasis on single and well fed) Cheers!

Dude, come on man. Ok Here we go. First of all I apologize if I come across as pedantic or condescending, it is really not my intention. That being said, please inform yourself before giving ill advice on how to use electronic equipment. Take a look at the uni-t product specification for the clamp mete, particularly at the current capabilities: DC Current (A) 2A/20A/100A ±（2%+3) and consider this is a 2000 count meter. that means that if you are gonna measure a current in the order of (3*10^-2) A, your precision is gonna be ±2% (not a big iss

Keep using the meter that you have, clamp meters are only good for fairly high currents otherwise the precision will screw you over big time.

Are you for real? Or just trolling?

Something like this but on a bigger scale? http://www.ebay.com/itm/DIY-KIT-AS1424-digital-Level-Meter-Audio-LED-Display-Flashing-Spectrum-Analyzer-/282217008133?var=&hash=item41b571cc05:m:mnp9OmwUrJIY6aYDgS6893w Sure its more than possible. Look into arduino FFT as a way to start

Not as portable though. The really amazing thing about the spark is all the technology they managed to put into such a tiny form factor while still maintaining a 10+ minutes flight time.

DJi dominating the drone enthusiast market? HAHAHAHA yeah right. Still a great vid though

If the amp works with 5v and draws less than 1A, then it should be perfectly fine.

Use HDMI. VGA is garbage in this day and age, stay away from it. Some "DVI-d" cables are actually fake, try to stay away from the cheap and thin ones.

Just provide the strip with 12v and enjoy the lights. The strip has integrated current limiting resistors. Cheers!

What I'm trying to say is that connecting the solar array directly to the battery without any form of proper charging circuitry will significantly reduce the lifespan of the battery. Most Lead-Acid batteries don't even like being charged at more than 0.5C, and given the capacity of the battery (what I estimated) the solar array will charge it way too fast, not to mention the lack of proper monitoring. Sure it can be done, but its janky AF.

@cj09beira 10 virtual cookies say you are wrong: Data taken from here: http://www.bestbuy.com/site/cyberpower-450va-battery-back-up-system-black/3938808.p?skuId=3938808 Best case scenario: 7 minutes at half load. Load = 260W of real power. 450W of apparent power. 130W * (7/60)h = 15.67J of energy provided. Assuming converter is very efficient (85 ish percent): (15.67/0.85)J = 18 ish joules. Average lead acid battery voltage: 12v --> (18 Wh /12v) = 1.5Ah of battery capacity Also, charging phases: http://batteryuniversity.com/learn/article/charging_the_
