Re: RC Flying POV LED Strip

Here is a ground test image.
I held the wing and rode a bike at about 15mph.

Re: RC Flying POV LED Strip

Maiden flight was a success.

A few clicks down trim and a few left and it was perfect.

CG is great

Re: RC Flying POV LED Strip

Looks great. Your starboard/port color scheme gives it a nice touch. Using long shutter times on the camera at night could make great pictures. Could the plane be controlled to draw a Raspberry logo in the sky? Or perhaps it requires too exact control of the flight. You could get some great photos ...

For loop break interupt

I am now working on the final draft of some code that controls addressable RGB LEDs in a strip and I could use a bit of help. I want to break out of a for loop as soon as possible "if pw1 != x or pw2 != y" located in def toggle12() line 228 I can't get it to work. it will loop through the entire ima...

Re: RC Flying POV LED Strip

Re: RC Flying POV LED Strip

Have you thought of SPI controlled LED's? Or is the Dotstar stuff the same thing? In QLC+ (http://www.qlcplus.org) you can control LED snakes and RGB panels over SPI. LED's like ws2801. It also has built in control of fonts and image displays. Yes! I am using SPI to control these LEDs. These "APA10...

Re: RC Flying POV LED Strip

ITS ALIVE!!!

That little red led near the start is caused by less than perfect wiring(jumpers everywhere)
and will disappear once everything is soldered in place.

Re: RC Flying POV LED Strip

I figured it out.

I power and ground the Level shifter with the Raspberry pi 5v/GND.
The LEDS are powered by the UBEC directly.

Re: RC Flying POV LED Strip

I got the MOSFET working. It defaults to OPEN when the GATE is under 2volts. So when nothing is connected to the gate the leds get power. If I send a HIGH signal(5v) to a GPIO pin connected to the GATE of the MOSFET then the leds will turn off. PWM_dutycycle.py import pigpio pi = pigpio.pi() pi.set_...

Re: RC Flying POV LED Strip

A few questions Does the mosfet need a resistor to prevent back feeding the rpi? Using gpsd to read the GPIO is proving to be very difficult. Should I just give in and connect the gps to a micro usb? Does anyone know a good method for reading PWM? Accuracy is not extremely important as I will only b...
