Evgeniy commented on LightWare - Laser Developer's blog post Obstacle detection LRF takes 36000 readings per second and costs only US\$350
"@LD! Thank you very much! Very good and detailed answer! Now just learn fast and accurate navigation in the veri big room and do not see any similar devices from other manufacturers. Especially in this price category. Very cool! If my code comes to…"

"Hi LD! Very cool device! Say please what if two devices will shine at one point (or in a area that is seen both devices)? If this problem is solved, how many devices can operate simultaneously?
I looked at that Beam divergence :: 0.2° and it 17cm on…"

"wow! 27 kg is 270 newtons. Then it's really good strength"

"Ok, while the bricks are on the copter him a force F = mg. Suppose bricks weigh 10kg. Take the acceleration of free fall for the convenience of g = 10 m / s ^ 2. Получим F=10*10=100 newtons.
Now suppose copter falls. For example with a height of 2…"

"Hi! On photo is static load, how about dynamic? I do not know what is the weight of the bricks, say 5 kg. Then two bricks will operate with a force of about 100 newtons.
But in life with dinamic load If the copter fall at a speed of 5 meters per…"

"is bad DC-DC converter. when DCin/DCout is more than 2 and amperage 1-1.5A he very hot! After 30seconds i cant touch he more than 2-3 secons. I've heard that kis-3r33s is much better!"

"practical value for this development?
a large drain on the battery when the energy goes in one direction and some in the opposite direction, it is best to do if you want to suspension, easier and more reliable"

"Unfortunately because of the lack of more detailed tests of high motor, such as motor tiger is very difficult to find the optimal pair of engine-propeller. The site tests are limited to manufacturers of engines propeller 17 * 5.5, but reason tells…"

"John Maffetone
if take the motor MN4014-11kv330 with Prop DJI15x5 we take from one motor for 8A the thrust 1500 (with 5s battary)
Battary 6s11Ah weight is 1235g, if we make quadrocopter then we have ~200g from each motor (1500g-1235g-149g motor)…"
