Interactive lathe turning from drawing
Lathe turning from DXF drawing is intuitive and easy way to make parts of any shape.
Welcome back 0603. HF PWM efficiency tests
Tests of 0603 vs 0802 at high frequency PWM. 0603 shows 60% flight time enhancement and this flight time is 17% more than the best of 0802.
Why high frequency PWM increases efficiency
Explanation of higher efficiency with PWM frequency, efficiency vs damping and theoretical limit of efficiency improvement.
JFlight (JESC) efficiency 24kHz, 48kHz
JESC efficiency measured for 24kHz, 48kHz damped and undamped versions.
DJI FPV AIR UNIT to BETAFLIGHT communication
MSP (MultiiWii) protocol exchange between DJI FPV AIR UNIT and BETAFLIGHT MSP port.
On XT30-caused damage
Replacement of 2xPH2.0 to single XT30 in 2S whoop often burn voltatge regulator out. Here I consider why it happens and possible methods of prevention by numerical simulation of the circuit
0603 vs 0802
0603 and 0802 motors are compared. The reason of different flight time is a bug in BLHeli_S firmware that affects 0603 motors. The thrust and rpm curves are the same, the only difference is current consumption caused by excess braking.
30% more flight time by ESC FW mod!
Proof-of-concept ESC firmware mod makes flight 30% longer. Video tests.
