4ld: ESC calibration

The kit I brought from RCTimer included 4 ESC running the SimonK firmware. This firmware allows to calibrate the minimum and maximum values for the PWM signal. First you must connect the ESC directly to the receiver (bypassing the Naza flight board) on channel 3: I also verified the motor direction of each motor, based on  the diagram included in Naza manual. To…

4ld: the kit from RCTimer

I’ve finally received the Quadrotor kit from RCTimer. This kit includes: [checklist] a class-450 quadrotor frame (clone of the DJI’s Flame Wheel F450) four 30A ESCs with SimonK firmware four brushless RCTimer 2830-1000KV motors four plastic propellers [/checklist]       Unfortunately I didn’t realize reading the kit description on RCTimer website that the motors include the 3.5mm banana plugs but the ESC don’t;…

4ld: the flight control board

I ordered the Naza-M Lite from Bizmodel, an italian DJI reseller and therefore I received it few days after my order. The main task for a flight control board is to adjust the power of the motors in order to stabilize the quadricopter, reducing the unwanted movements (oscillations, rotations…). More advanced control boards, like the Naza ones, are also able to automatically maintain the…

BlueMatrix

My latest project is a led matrix display, portable and controlled via Bluetooth from a PC or from an Android smartphone; I named it BlueMatrix. Here’s a short presentation video (non-italian guests: remember to enable english subtitles); in the next pages you’ll find some details about how it was made and how it works:
