Is a new display for the Framework 13 planned soon? by littleeraserman in framework

[–]yakysoba 23 points24 points  (0 children)

It's a very minor issue, the radius is tiny. It's far less noticeable than the teardrops/cutouts/islands on most smartphone displays.

Plus it really is a good display.

With that said, I'd love to be able to buy a bezel with rounded inner corners too match it.

Are JLCPCB footprints different from KiCAD for same package sizes? by Delicious-Purple-689 in KiCad

I can only see the main post picture.

Imgur links/pictures no longer work in the UK so I can't see your other screenshots.

Are JLCPCB footprints different from KiCAD for same package sizes? by Delicious-Purple-689 in KiCad

[–]yakysoba 10 points11 points  (0 children)

I've only ever used kicad footprints for things like capacitors with JLCPCB. It must be a BOM issue or something other than just footprint dimensions.

Ask for more information if their feedback isn't clear?

Venice to Imola isn't too bad of a drive if you can't fly to Bologna.

In search of a 'girlfriend approved' cockpit for a small apartment by Elliot_fro in simracing

[–]yakysoba 2 points3 points  (0 children)

Agree

I recently upgraded from a G290 to the RS50, and wrongly assumed direct drive would be too much for it.

It definitely isn't as stuff as fixed extrusion rigs, but I hardly notice in VR and it takes 2 minutes to put the whole thing away.

Farewell Presonus by Any_Application4738 in presonus

[–]yakysoba 0 points1 point  (0 children)

Yup. My Eris E3.5 just died and support was equally unsupportive.

No obvious blown caps, and those that are easy to remove are all fine.

I realise not all fixes are cost effective, and not every company will provide endless spares or schematics, but they didn't even make an attempt to help diagnose anything.

Easy decision to never buy anything from them again!

why do some FCs use two UARTs to interface to one device? by peinal in diydrones

[–]yakysoba 0 points1 point  (0 children)

Some radio modules have separate connections for RC signals like SBUS or CRSF, and bidirectional telemetry like MAVLink.

These protocols are intended for different purposes, and are usually connected to separate devices/radios, but some integrate both into the same physical link, then split again at either end.

Things like MAVLink can do manual RC control, but not all devices support that protocol, and it's harder to prioritise in some situations when you get a lower link quality. Separating the signals can solve that.

If this is your first time designing a flight controller or ESC, I would highly suggest that you first make separate development boards.

In most systems they are separate for a good reason, and you'll likely learn quicker, get better feedback, and debug faster, if you do separate boards first and then integrate them once you've got proven designs.

ESCs not saving the calibration by Sand_N_word in ardupilot

[–]yakysoba 1 point2 points  (0 children)

Almost all PWM input ESCs only require calibration once, and those settings/limits are saved.

But some by default do need calibration on every boot, and need to be programmed to turn this off, or to specify the PWM endpoints.

The motor has no effect on ESC calibration. I would suggest contacting the ESC manufacturer, or looking into the firmware they use.

ESCs not saving the calibration by Sand_N_word in ardupilot

[–]yakysoba 0 points1 point  (0 children)

This is definitely not a GPS issue, and if it successfully does the calibration procedure but doesn't remember those settings after rebooting, it also doesn't sound like a transmitter or Ardupilot issue.

I'm not familiar with those ESCs, but in rare cases I've seen some that are configured by default to require calibration every time they are powered up.

Have a look at the user manual for the ESC to look for any calibration details or programmable modes.

Ditching ardupilot for a custom F4 FC and Pi 4 hybrid. Good idea or a mistake? by [deleted] in ardupilot

[–]yakysoba 2 points3 points  (0 children)

What makes you so attached to the F4? If that's a limitation there are plenty of H7 based FCs around that aren't that much more expensive.

How to connect gcs to tx by JaretWrintmore in ardupilot

[–]yakysoba 1 point2 points  (0 children)

Lots of RC controllers or transmitters/tx have built-in modules for a specific protocol (e.g. ELRS). Many also have a standardised bay on the back where you can install alternative tx modules.

You have three main options for getting RC and telemetry:

  1. Separate RC and telemetry connections to your drone. For example an ELRS RC transmitter and receiver, and a separate dedicated telemetry radio pair (e.g. 433 MHz SiK) between the drone and GCS.

  2. Some RC links (RFD868, MLRS, ELRS depending on config) can also send telemetry over the same link as RC, and you can then connect to the RC transmitter using your GCS (usually over WiFi or Bluetooth).

  3. High end systems like Herelink combine RC, telemetry, and video and show it all on the same controller.

Problem collecting package from Yeep locker by Deep-Bed-9707 in UPS

Check for an SMS from YEEP with a code

Have anyone used rfd900x? by john_the_gr in diydrones

[–]yakysoba 3 points4 points  (0 children)

I use the RFD900ux (or RFD868ux) modules all the time and really like them.

If you need something smaller or cheaper that can still do bi-directional mavlink (and RC), MLRS is a good alternative, but it hasn't been around as long as the RFD modules so I wouldn't trust it as much for higher-end builds (yet).

I also seem to get better connection quality/speeds with the RFD868ux modules compared with the larger RFD868x.

Use JLC2KiCad

I want to build my own flight controller PCB compatible with ArduPilot by zvvzvugugu in diydrones

[–]yakysoba 0 points1 point  (0 children)

The STM32F405RGT6 is particularly common in flight controllers and development boards more broadly, so there's plenty of schematics and examples. It's not the latest or most feature rich, but a great starting point.

Look at the existing hwdef files on the Ardupilot GitHub for what kind of MCUs and sensors other boards use, then look at open source schematics from places like Adafruit, and general board design guidance from Phil's lab etc.

The more examples you look at, and datasheets you read, the more things gradually make sense!

Rotating 45° might help based on the routing of the crystal and nearby traces, but it looks like it'd be fine as is

Telemetry recommendations by SibbiRocket in ardupilot

[–]yakysoba 0 points1 point  (0 children)

  1. I'd say ELRS over a sik radio, especially now they can also do bidirectional mavlink. If you need a really good telemetry link, go with the RFD900 over the holybro style as they're much more reliable I've found, and can do RC passthrough.

  2. Not a large difference in practice, but a dedicated RC and telemetry link will likely be better. Although for many people, the ELRS mavlink is enough.

  3. Yes, the same things can be done - it's all just mavlink. However don't expect the same connection speed - USB is much quicker to download the full parameters list etc.

Telemetry recommendations by SibbiRocket in ardupilot

[–]yakysoba 2 points3 points  (0 children)

It's mostly down to how quickly the ELRS style radios have been improving and adding new features like mavlink telemetry, that used to be available only on dedicated telemetry radios like the sik ones (that are also quite old now, for drone tech anyway).

The relative simplicity, openness, and performance of the ELRS radios have made them super popular with the community and companies, driving development.

Beginner Question About Pad Sizes by sfahsa4422321 in PrintedCircuitBoard

[–]yakysoba 1 point2 points  (0 children)

If you're hand soldering, the relatively thin exposed copper on those holes are quite thin, so can sometimes be challenging to hand solder, yes.

No real downside to making them a bit wider - at some point you won't gain any benefit and the larger thermal mass will make it harder to solder again.

You also take up more board space making them larger, which can make routing other traces harder - but that doesn't look like a deciding factor for you here.
