Merry belayed Christmas and a happy new year everyone. I know, I am running a tiny bit late. My original plan was to release the tinyOSD and tinyFINITY sources ready for Christmas but then the usual things got into the way and I had to postpone this post. But here it is: I am releasing… Read More »
In my previous post regarding the display module of the $99 Eachine EV100 googles I tracked down szsonicom as the manufacturer a reseller (?) of the display assembly. As it turns out the actual manufacturer of the display is CITIZEN. When you browse their product portfolio you can see a picture of the display assembly that… Read More »
It feels like christmas is fast approaching this year… The days got quite short, trees are losing their leaves, and it is getting colder already. And now look what Santa Charles Blouin from RCbenchmark just sent me: Wohoooooooo… The postman, or rather the customs employee, handed over a 1580 dynamometer motor test stand to me!… Read More »
Some weeks ago I wrote about using a silhouette portrait craft plotter for cutting solder paste stencils. The described process uses the collection of the gerber2graphtec python scripts to process the fabrication data from kicad and send the cutting instructions to the plotter. The solder paste stencils I did cut for the VESC came out… Read More »
Roughly one year ago I started to work on the 1S tinyPEPPER ESC. At first, I did not want to design an ESC on my own. I had just finished my first tinyFISH FC PCB routing and was browsing banggood for a tiny and lightweight 1S ESC. To my surprise I could not find anything… Read More »
I just started to swap the hardware abstraction layer that runs the low level stuff on OpenGround. On modern 32 bit processors you usually get a small abstraction library from the manufacturer. This library maps complex commands such as initializing e.g. the SPI subsystem to the underlaying low-level register access commands. For the stm32 series… Read More »
During development of my tinyfish FC i used the st-util gdb bridge for debugging. I had some issues using it, mainly unstable usb communication etc. Therefor i switched to openocd. Recently i have read a lot about the very nice blackmagic probe, the best part is that the firmware can be flashed into the cheap… Read More »
I am working on a custom 4in1 blheli_s ESC for micro brushless setups. I wouldn’t like to reveal too much at this point, except it is going to be tinytiny (20x20mm) as you have seen with my version of a Frsky compatible tiny rx (see my uSKY project). UPDATE: you can find more about the… Read More »
This is the 11th post of my series documenting the development of a custom firmware for the FS-i6s transmitter. CC2500 adapter In order to remove the mess of cables inside the modified transmitter, i designed an adapter pcb to adapt the CC2500 transceiver module to the pads on the transmitter pcb. It’s no rocket science… Read More »
This is the 10th post of my series documenting the development of a custom firmware for the FS-i6s transmitter. This is just a quick update on my progress. Radio protocol The radio link is functional. It is not tested thoroughly and is missing a lot of safety features, do not use it right now! Transmission… Read More »
