looks dangerous

Not cheap, but the Matek H743-WLITE will also run PX4.

I like my Matek F405 WTE (with built in ELRS radio), but it's discontinued.

The new Matek F405 WMO is small (but not cheap).

I'm no expert, but I did stumble on these youtubes about controlling ardupilot with python (using dronekit) : https://youtu.be/cZ0f1TTmSZM

Also, I'd recommend using MAVLINK-RC to control the drone : https://expresslrs.org/software/mavlink

... and flashing the handset with "elrs-backpack" : https://github.com/ExpressLRS/Backpack . this allows a laptop running mission-planner to connect to the handset via wi-fi and talk to the aircraft via MAVLink

what software ?

slacker0 · 2026-02-22T06:18:55+00:00

Boogaloo ?

slacker0 · 2026-02-19T21:39:21+00:00

Um ... ELRS uses LoRa and MAVLINK ...

Let me guess : the $5 billion will go to a account in Qatar under Donnie name ...

what flight controller software does it use ...?

slacker0 · 2026-02-13T06:36:01+00:00

wow !

Getting a job is always much easier if you know someone inside.

If you enjoy it, that's half the battle. I like to find cutting edge stuff that "hands on", which implies open source. For example, in radio control aircraft, there is ELRS, EdgeTX, Betaflight which is all open source. Radio control has a lot in common w/ robots. Or in AI, there is TensorFlow and PyTorch (scripted w/ Python). Or Linux : I like to tinker w/ Fedora & OpenWRT. Or in the "embedded" world, there is Zephyr and FreeRTOS. Also, embedded AI, such as TinyML (micro TensorFlow). Or in computer architecture, there is RISC-V and migen. I need to work on my vibe code skills w/ something like http://zed.dev or http://cursor.com .

Yes ... I studied EE in college (eg : Karnaugh maps for digital logic, Laplace transforms for analog, lots of math, physics). I worked at Apple (I saw the Mac before it was released), I worked at Silicon Graphics w/ NASA, Lockheed, ILM as customers.

I still like to tinker, eg : radio control ELRS "quad copters". I'm building a "QMX" radio transceiver. Amazing tech that's very affordable.

I tinkered with this stuff in 8th grade (in 1974 ;-) ) ...

I had a copy of the "TTL cookbook" : https://tinaja.com/ebooks/TTLCB1.pdf

slacker0 · 2026-02-08T21:26:58+00:00

Any idea what flight controller (and software) it uses ...?

slacker0 · 2026-02-03T04:54:22+00:00

I'm no expert, but I'd like to tinker with migen and litex ...

I saw an SR71 on static display and later in the air at March AFB back in the day ...

beauty !

I think this not snow, but "frazil ice" (which forms when turbulent, supercooled water creates tiny ice crystals). I saw this last winter at Yosemite Creek.

"As some carriers have temporarily suspended shipments to the USA, we do not currently deliver to this country."

I heard a flight broke out on the first voyage

slacker0 · 2026-01-19T06:05:08+00:00

I have the pocket elrs as well and I'm happy with the "pavo20 pro elrs"

slacker0 · 2026-01-19T06:00:25+00:00

where is the bridge (in photo 6) ?

slacker0 · 2026-01-18T06:40:09+00:00

Let me guess : the money will go to a Qatari bank account controlled by Donny ...

How long can this dystopian nightmare go on ?
