I recently got reports of buzzer problems on the tinyFISH FC and the F3D8 clones. The buzzer beeps on startup and is constantly on afterwards… One of the FC leds does not light up properly as well. Do not throw it away, there is an easy fix! When I routed the final version of my… Read More »
As you all might know racerstar cloned my opensource tinyFISH FC and tinyPEPPER 4in1 ESC, claiming it is their very own invention. Sadly they messed things up… There are lots of reports of not all motors spinning when you arm the FC with a fully charged Lipo battery. The symptoms fade away once your battery… Read More »
It has been a long time without new posts. I was fully occupied with our move. Most of my quadcopter equipment is still packed in boxes and I traded my soldering iron with a brush and I am still busy painting walls. At least my desk is partially finished and I can start to work… Read More »
Well, it finally happened. China took one of my designs, removed my logos, renamed it (what was wrong with tinyFISH FC?), and started selling it as their creation: The “Racerstar” F3D8! But let’s start from the beginning: On November the 21st 2016 I started to blog about my tinyFISH FC. I developed it because I… Read More »
In this post I am going to share all the parts you need to build your own super lightweight tinyFISH flight controller with an integrated, FrSky compatible rx. All the following information applies to the current version 0.2b of tinyFISH (tagged as revision 0.2b). Changes compared to the previous revision 0.2: fixed the numbering of… Read More »
Some weeks ago I added a bootloader mode to my custom FrSky compatible firmware OpenSky for commercial or DIY receivers. This allows hassle free updating of the OpenSky receiver firmware using the STM32 bootloader protocol. For targets such as the D4R-ii or others using an STM32 processor with the factory programmed bootloader nothing special had to… Read More »
The first community built tinyFISH fc is alive! I recently got an email from the rcgroups user Sevo. He successfully managed to assemble and flash his tinyFISH fc. Congratulations, this is the first report of a working replica from the community! Even though he had no access to a microscope he managed to complete his… 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 »
