    Ideas for a brushless motor??

    Hi everyone, new to this place. So long story short, I used to have an aerial photography business using drones a few years back, one of them fell and broke and it was a beast; it was an octocopter with a 1.2 mts span (about 5ft I think) and I think it could lift upto 10kg but obviously never...

    Understanding two Multivibrator models

    Hello, I simulated the two multivibrator models in CMOS technology using the cadence tool. I was expecting the model 2 with Schmitt trigger(ST) will show robustness in PVT (Process Voltage temperature) analysis as compared to model 1 due to ST. But this was not the case both the Models shows the...

    Is it possible to model a photodiode PIN InGasAS, in accord with datasheet, in simulator SPICE MicroCAP12?

    I want to know if it is possible to model a photodiode InGasAs panchromatic PIN , in accord with datasheet, in simulator SPICE MicroCAP 12.Because the supllier where I boughit it has not a SPICE model.And if it is possible, which are those steps. Here it is data-sheet...

    DC link capacitor values calculation in a 2 leg inverter

    Dear All, I would like to know the formula to calculate the capacitance for two capacitors whose midpoint is connected to a third phase of brushless dc motor (For simplification one can consider "series RL" load connected in WYE or DELTA fashion). Overall its about driving a 3 phase motor with 4...

    Wall hidden pressure sensors for home security

    Hi, I am thinking of designing a total home security system which can produce alert sirens, lock the doors automatically, send sms to owner's mobile and call #100 for police assistance. My idea is to design > A pressure sensor (parent sensor) microchip which can be pre-set to a warning pressure...
