This is the 12th post of my series documenting the development of a custom firmware for the FS-i6s transmitter. This time I am going to have a look how the Turnigy Evolution differs from the FS-i6s. BOOT pin The BOOT1 pin is still available on the resistor R59, pull the side connected to the STM32… Read More »
You want to fly a pepperF1SH but you can’t wait for commercially available tinyFISH FC and tinyPEPPER ESC clones? This is your chance to join the pepperF1SH WORLD TOUR 2017 I want to send a pepperF1SH quadcopter around the world. The idea is simple, you can apply to become the next hop on the world… Read More »
Have you ever assembled your quadcopter motors in the wrong order? I am quite sure you did! I am going to show you how to swap motors in betaflight without the need of a soldering iron! This tutorial is based on betaflight 3.0/3.1 and betaflight configurator 1.8.9. I have spent a lot of time reordering… Read More »
We had a tinyFISH FC soldering party last weekend. I met with some friends and we soldered a total of four tinyFISH FCs — there will be four more pepperF1SH copters soon! All four boards are working fine, I just finished flashing the betaflight and opensky firmware to the FCs and did a simple 1-point… Read More »
In the previous tutorial we flashed the betaflight firmware into the STM32 of our flightcontroller, this time we will flash the tinyFISH FC receiver firmware. We are going to use the frsky compatible OpenSky firmware. You can now decide to download the latest version of OpenSky here and build the tinyfish target yourself (make TARGET=TINYFISH).… Read More »
This post will show you how to calibrate the on-board current sensor on any betaflight based FC. I will do this based on the tinyFISH FC, your FC will probably need some different values. This tutorial is based on betaflight 3.1 and beteflight configurator 1.8.9. Tools needed: a flight controller of your choice with built-in… Read More »
Assembly done — and now? So you just assembled yourself a tinyFISH FC ? Congratulations, you just completed the hardest part. Uploading all software bits and bytes should be quite easy compared to those 0402 sized components — so first of all relax! You will need the following tools: tinyFISH FC Soldering iron Lab power… Read More »
pepperF1SH This post is the 15th in a series of posts about the adventure of building the world’s lightest brushless FPV quadcopter: project pepperF1SH. Long time no update on the pepperF1SH… I was busy testing new prototypes. I did some tests for the smallest framesize possible. Right now it is 50mm motor-to-motor spacing and uses… Read More »
I recently bought a SkyRC quattro / Hitec X4 charger for my TinyWhoop and pepperF1SH batteries. Unfortunately this charger does not have the 1.25mm molex picoblade connector you find on the standard picoblade connector used on the TinyWhoop batteries. The MX connector is a close fit, but having a different spacing (1.5mm VS 1.25mm) damages… Read More »
Space grade titanium screws for your quadcopter Some people use aliminum screws to mount the top and baseplate of the typical H shaped frames to save some weight. I know it’s not a lot, we are talking of < 10grams for inox M3x6 screws. When reaching for the holy 250g limit you often end up… Read More »
