Lipo batteries degrade over time, sometimes this degradation results in dead cells. It seems to be a waste to throw the whole pack away because other cells might still be working. In this post we will show you how to make a working LiPo by combining the good cells from multiple damaged/defective batteries.
Capacitors can make your FPV video signal cleaner, and your mini quad fly better. In this tutorial we will explain what types of low ESR capacitor you should get and why low ESR is important, and where to install the caps in a racing drone.
This post shows you how to program ATtiny 85 and 45 micro controllers using the Arduino as an ISP. I also explain the advantages of using Attiny chip over Arduino for DIY projects. Read More
The inevitable question for RC hobbyists is how to get rid of old or damaged LiPo (Lithium polymer battery). There are tons of videos online showing how dangerous LiPo batteries can be if not handled correctly, causing explosions and fire. In this guide we will show you how to dispose damaged and old LiPo batteries safely.
LC filter is one of the most basic filters in electroincs, which comprises of just one inductor and one capacitor in its simplest form. This circuit is widely used by FPV hobbyists to suppress noise in power created by ESC and motors. Read More
Proshot is a new ESC protocol that encodes DShot using PWM pulses. In theory there might be some benefits in using Proshot over DShot. However whether or not it makes a noticeable difference and overweight the downsides, that’s another question.
I will show you how to flash Frsky receiver firmware on your R-XSR, XSR, D4R-II, X4R-SB, XM+ and some other RX. Updating RX firmware is useful when you have the wrong firmware that prevents you from binding, and getting the improvements and bug fixes in the latest firmware.
Antennas for FPV can be categorized by their polarization: linear and circular. In this article we will discuss the differences between linear and circular polarized antennas.
The gain of an antenna could change the radiation pattern, and it reflects what the maximum range is going to be for the FPV antenna. In this article we will discuss how antenna gain affects range, and the pro’s and con’s of high gain antennas.
