Standalone Betaflight Configurator, since Chrome Web Store apps are dead

Google finally did what they announced last year: Chrome Packaged Apps for Windows, Mac, and Linux are dead. OK, maybe not 100% dead, but they were removed from search and browse in Chrome Web Store. If you still have link, you can install (no idea for how long tho).

So, how to live with that? Our hobby is driven by Chrome Packaged Apps. Betaflight Configurator, INAV Configurator and Cleanflight Configurator are all Chrome Packaged Apps. Did we lose the ability to set up our drones? Luckily no. Thanks to fantastic project NW.js, chrome apps can be packed together with Chromium and distributed as a single file without dependencies. I've prepared a short video how to install Standalone Betaflight Configurator, for INAV it's the same procedure. And for Cleanflight… well… Cleanflight is dead. Or rather dying…

Arduino hygrometer with DHT11 and SSD1306 OLED display

One of the things I like about Arduino ecosystem is that you can prototype pretty decent device in very short time. It might not be pretty, but will work. Just like my DIY hygrometer built with DHT11 and SS1306 OLED display I've built few weeks ago:

Simple, efficient and runs on 4 AA batteries. The best part is that it can be powered all the time. Arduino does humidity measurement, display the result and then powers itself down to conserve power. Cool, right?

How to wind an electric brushless outrunner motor with dLRK winding schema

This time, another "motor winding" video. In 13 minutes and something seconds I:

  • show some tool that I find useful for motor winding
  • wind a 12N14P brushless outrunner electric motor with dLRK winding schema
  • terminate this motor into Delta configuration

BTW, in next video I will show you if it worked or not 🙂

Video tutorial: 5.8GHz Inverted Vee antenna for FPV

Today another video tutorial. It's just simpler to show how to make something on video than with text and images. So, without further ado: How to make Inverted Vee antenna for 5.8GHz FPV at home. All that is required is:

  • coax cable (here RG316)
  • SMA/RP-SMA connector
  • copper welding wire
  • caliper
  • soldering station
  • basic tools

At the end we have small and light FPV antenna that just works. Sometimes it's just worth to make something by yourself, right?

Crossbow LRS, range test that did not went well….

Yestarday I wanted to make a first "real" range test of my DIY LRS system. "Real", because RX was supposed to be on a flying wing, but only as an passenger. Actual control was supposed to be happening via FrSky X8R. Crossbow RX was only to measure RSSI and check for failsafes.

It, well, did not ended up very well. Just watch the video.

Toy Stirling engine = best toy ever and best Christmas gift?

How is it until Christmas? 2 months and something. Pretty close. And like every year there will be problem: what to buy someone who has everything? Tough one, right? Sweater? Socks? Toy Stirling engine? I vote for Stirling engine for sure. There is only one precondition: recipient has to like mechanics 🙂

I’ve tested the cheapest toy Stirling engine from china you can get. For less that $20 you get a functional engine model that, surprise, surprise, works. Amazing, right? Here is my video review of it:

Oh, by the way, for me, this is the best toy ever!
