"FYI: Take a look at the Tiger motor specs. It will show thrust per motor for various prop sizes at different voltages(3S,4S,etc.). Additionally, I prefer hard case batteries. I know there is a bit of added weight, but the resistance to puncture in a…"
First you need to determine the maximum power required for the weight of the machine; thrust and full speed movement.
Determine the thrust required to hover (defeat gravity); how much total weight is to be lifted. Thrust for each motor =…"
"Hey Cedi, The MPU9250 (an obsolete component) uses the AK8963 Hall effect sensor and the MPU6500 gyro/accel. The LIS3MDL is a magneresistive sensor, so I would expect the output of the two LIS3MDLs to have similar quality of their plots..
"First of all, it is illegal to jam ANY radio frequency in the US. Jamming devices are illegal. penalties are severe...

Additional,any GPS jamming OR INTERFERENCE would affect the GPS device in a car and any other device using…"
"I'm waiting for a win on MegaMillions...$658mil today!
Seriously, I'd rather see posts by people who have reviewed the book; announcements are fine. PLEASE don't post that you are waiting for shipment; ha!...However, please do post a…"
"Yawn...GoPro 6 had EIS. More hype. Loss of 5% of the image area! A gimbal maintains a parallel relationship with the subject, which this does not; inherent distorting the perspective. I'll wait for GoPro 10 when it really really really works!…"
"That's the latest and greatest 70Ghz technology. 24Ghz has been out for a while. 24Ghz RADAR from Infineon
24Ghz chip is about $7 in single quantity. The $125 part from TI will no doubt come down to less than $10 each once it is in…"
"Another option and perhaps better solution will be the new RADAR chips from TI. Originally intended for automotive use they are releasing an industrial version too. None of the problems associated with LASER ranging. These are uses to detect…"
"GPS uses a radio receiver which operates at about 1.5ghz. As long as no RF blocking material blocks the signal (coming from satellites overhead), the GPS will receive data. RF blocking material; metal or carbon fiber (i.e., electrically conductive…"
Yeah! That's what I was talking about. They use three 24A/190A burst MOSFETS in parallel with a couple of flip-flops set by PWM. Although it is only for 3S, some beefier MOSFETs would fix that.
Additionally, probably some…"
