Lipo battery balance plug can sometimes be damaged by spinning propellers in flight. it’s extremely unsafe to use this LiPo with a broken balance lead as it can short itself easily and cause fire. In this article I will show you how I fixed mine.
The new GoPro Hero 2018 edition is cheaper than the Hero 5 Black, but it won’t do 4K nor 2.7K, only up to 1440p. There are some other features missing too. Interestingly there are smart people out there managed to turn it into a Hero 5 Black that is capable of recording 4K videos!
The Fatshark battery case is a convenient holder for 18650 cells. However it’s not designed for charging, and you have to take the 18650 batteries out of the case to charge them. It’s quite annoying so I decided to modify the case so that I can plug it straight into the charger for charging.
Buzzer can help you locate your crashed drone, but typically it won’t work if the battery is disconnected in the crash. Here we will show you how to build a DIY lost model alarm with its own little built-in battery.
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
Before throwing away damaged or old LiPo batteries, you should first drain them completely until there is no charge left. In this article I will show you how to build a battery discharger using high power resistors.
In this post we will share some findings and results regarding the latency of FPort receiver protocol. Separate tests were run on the XSR and R-XSR RX’s, using a logic analyser.
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
The Frsky X-Lite has an external module bay that is too small to fit standard size JR modules including the TBS Crossfire. Are we giving up that easily? HELL NO! A few people have been taking the X-Lite apart as soon as they received the the first batch, and trying to find out whether they can get it working.
Mr Markus Grocholewski shared some amazing photos with me where they took at 36Km above ground using a balloon. The shots are simply breathtaking, so I asked him why and how he managed to send a balloon and camera to space.
