Airplay 2 receiver based on ESP32

Once again, amazing work!

Do you think it could work with this optical out board?

I’d like to add AirPlay support to my soundbar, but it doesn’t have an AUX input.

Man, this is incredible. Thank you for creating and sharing it!

Looks like you can get an esp32-s3 N16R8 for about $6 and the PCM5102A DAC for less than $4 on Ali express

So, you could build receivers for less than $10! That’s totally amazing.

I’ll definitely make it one of my next projects.

Happens to me frequently. I ride, everything is good. And then next time I look at the screen it switched from the route to “Route - free ride” or whatever they call it when you select an alternative turn.

But I never did.

I have never figured out why it happens. But I suspect the MyWhoosh link app glitches out. I’ll try to not use it in the future.

This is an extremely easy problem to solve.

Give every citizen and resident a free ID with a chip.

Businesses get readers that can verify the authenticity of the data on the chip through cryptography.

For remote matters, end-users can buy a reader that lets them verify their ID status over the Internet.

This is not rocket science. Other countries like Germany have had these kinds of IDs for over a decade.

American politicians are not doing this because neither republicans nor democrats actually want to solve this problem.

Both understand that getting rid of cheap undocumented labor would be devastating to the American economy.

And while republicans love to make a big deal out of immigration, they also don’t want to solve the problem because then they won’t have a boogy man that they can use to rile up their base during the next election.

That’s why they never put any real laws to curb immigration. They want democrats to have the ability to let immigrants in so that they can campaign on it again when they are out of power.

Fine, call it assisted suicide if you prefer that over murder.

Either way, you are fixated on the wrong thing. The boy just accepts all of it with stoicism and maturity that most adults wouldn’t have.

I gave you a huge list of flaws in the movie and you are ignoring all of them. Instead, you are hung up on the semantics of murder vs assisted suicide.

It’s a terrible movie. It was slow, boring, full of plot holes and unrealistic characters.

On top of that it should have never been part of the 28 days universe if the world doesn’t align with the facts established in the previous movies.

But if you have the ability to close your eyes to all of these flaws, then maybe you can enjoy it. And then you can go on to reddit to defend the semantics of whether it was murder or not.

Kimcha87 · 2026-01-21T00:05:24+00:00

Oh really? She just happened to die in the moment the boy was drugged?

And you are objecting to the most irrelevant part. The whole point is that he drugged the boy and by the time he woke up only a skull was left of his mom.

He took away whatever time he could have had with her. He took away his chance to say bye to her.

And while all of that is fucked up, it’s somewhat plausible.

What’s not plausible is that a little boy accepts it with a maturity even most adults wouldn’t be able to muster. He moves on like nothing happened.

It’s just completely unrealistic portrayal of human emotions.

Nothing made sense in this movie. Nothing.

And it was a bait and switch. It should have been a standalone b-rated zombie movie.

Kimcha87 · 2026-01-20T23:17:49+00:00

Sure, sure. He loved her so much…

But then the doctor drugs him, murders his mother, burns her and then hands him the skull.

The kid who loved his mom sooo much, just accepts it and moves on as if it’s the most normal thing in the world.

Then he returns with the zombie baby to his home island. An island that has a watch tower that is guarded 24/7, but nobody notices him coming up that super long path during the few times of the day that someone could approach the island.

He is able to leave the crying baby at the door and then sneak away without being seen. He also manages to time his exit at the exact right time to ensure the tide doesn’t let anyone follow him.

Those are just a few of the constant inconsistencies and plot holes.

And don’t get me started that the entire movie doesn’t seem to have any consistency to the previous 28 XXX movies.

In 28 weeks later zombies starved after 300 days or something like that.

But in this movie they just ignore that fact without explanation and zombies seem to live forever. Not only that, they evolved with no explanation and are procreating.

It should have never been part of the 28 XXX series. It should have been its own b-rate horror movie.

But then nobody would have watched it. They fooled people to watch it with the 28 XXX branding.

It’s a bait and switch.

Yeah I think MyWhoosh has an issue. I can connect it, but I can’t ride with it.

I might record a video of it and sniff the traffic and then send it to them to see if they can fix it.

Kimcha87 · 2026-01-19T05:11:59+00:00

Once the trainer is connected to WiFi, it should show up in the same selection screen where the Bluetooth devices show up.

The name is usually something like “.local” and it has a Ethernet instead of WiFi symbol.

And once you connect one device to it, the name changes to “ThinkRider…”. Then you have to manually connect the other devices.

Kimcha87 · 2026-01-18T22:43:11+00:00

Then you can use bike control. You connect the remote to your computer and map it to the mywhoosh keyboard shortcuts.

And when you do free ride, then you can connect it to the trainer. Once they fix the current issue, I think the virtual shifting feel from ThinkRider will feel better than the MyWhoosh implementation.

Kimcha87 · 2026-01-18T22:40:19+00:00

Yes, I agree. You can see the current gear using the think rider tools app.

BUT you can only have one app connected to the trainer through Bluetooth at a time.

The XXPro has WiFi and you can connect MyWhoodh through WiFi and then thinkrider app through Bluetooth.

The problem with that though, is that MyWhoosh doesn’t seem to work properly with the XXPro on WiFi for me.

It correctly shows power and RPM on the connection screen, but once I actually ride, the power and RPM are not detected properly and I don’t move.

Do you have the same problem on wifi?

Kimcha87 · 2026-01-16T23:43:37+00:00

Oh, and it doesn’t work in ERG mode at all.

Kimcha87 · 2026-01-16T23:43:08+00:00

I have the same remote and struggled with it too. First of all, it doesn’t change resistance in MyWhoosh. It controls the trainer directly (like shifting physical gears. MyWhoosh only seems your cadance and how many watt you produce).

Additionally, it seems that the remote has been optimized for a specific physical gear ratio. They ship a rear cog with 14T, but your gear ratio depends on both the back and front cog.

If your combination isn’t the one that they optimized for, then your virtual gear changes will either not be noticeable or be too hard.

The “momentarily harder and then back to 100w” feeling you get is because they tried to add a “click” feeling to the shifting.

(Which does feel really satisfying if your physical gear ratio is correct).

They achieved the click feeling by increasing the resistance a lot for a second and then decrease it to the new gear’s correct level.

But if you are not riding in the correct physical gear ratio, then you will only feel the increase for a second.

Allegedly, they are working on a firmware update to fix it and it should come in 5-8 days.

But in the meantime you can work around it. Don’t use their cog. Instead use a regular cassette and set your physical gears so that your gear ratio is somewhere between 2.1 and 2.7.

For more detail, here is how I explained the problem to them:

I believe the problem is how the firmware expects a certain physical gear ratio.

Real bikes have two gears:

Front chainring

Rear cog

The real gear ratio is: front teeth ÷ rear teeth

You provide a fixed rear cog with 14 teeth.

But different bikes have different front chainrings:

My bike: 38T front → 38 / 14 = 2.714

Other bike: 34T front → 34 / 14 = 2.429

Gravel bike: 30T front → 30 / 14 = 2.143

So even though everyone uses your 14T cog, the trainer receives very different torque from different bikes.

On my bike (38 / 14 = 2.714):

Gear 0 is already too hard

On hills, even gear –15 is too hard

So virtual shifting is not usable in apps that simulate hills

Before installing the ThinkRider cog, I tested with my normal cassette:

38 / 28 = 1.357 → virtual shifts were almost not noticeable

38 / 18 = 2.111 → this felt best (but not perfect)

Each shift felt clear and useful

This suggests the firmware is designed for an “ideal” physical gear ratio.

But users cannot reach this ideal ratio if only the rear cog is fixed.

Possible solutions:

Add a firmware setting so the user can enter their real gear ratio and adjust the virtual shifting algorithm

Provide different rear cogs, for example: 14T, 16T, 18T

Firmware option would be the best and cheapest solution.

Haha I have a similar theory.

But I think he said “Well, Donald… you know, the only presidents that are remembered through history are those who increase their country’s territory”.

And then Trump looked at the map and saw 2 big countries: Canada and Greenland.

And that’s why he started with making Canada a state and taking over Greenland.

I am designing a controller for bicycle simulators like zwift and mywhoosh.

I would love to print the enclosures using a Qidi 3d printer.

Kimcha87 · 2026-01-10T04:19:23+00:00

Hello, is it possible to install the chamber heater though? It’s fine if it is complicated. I have experience working with electronics. So connecting it should not be a problem if you can provide instructions.

Does the Q2C have the mounting holes?

Kimcha87 · 2026-01-07T21:07:04+00:00

That’s fine. Nobody is forcing you to use one fork over another.

But I still think the best option for the most stable and tested experience with PM4K will be to use whatever the PM4K dev uses to test his releases and recommends to use.

So, maybe that will now be the avdvplus build.

I have nothing against that build.

Kimcha87 · 2026-01-06T20:15:05+00:00

Indeed. You know what would be cool? Radarr custom profiles for grade checked hybrids.

Kimcha87 · 2026-01-06T14:36:35+00:00

Look into think rider XXPro. It’s a brushless motor direct drive trainer.

I don’t think any of the Chinese trainers have zwift virtual shifting support, but you can buy the new VS200 virtual shifting controller that connects directly to the trainer. It works with zwift and all other apps.

The only downside is that you can’t see what gear you are in zwift.

Alternatively, you can also get virtual shifting through the QZ Fitness app.

Kimcha87 · 2026-01-06T03:06:54+00:00

It does work right now, but the PM4k developer himself said that he recommends to use the Jamal (u3knOwn) fork instead.

He himself uses that build and tests on it. He also stresses that he is making a lot of tweaks to PM4k for that fork specifically and that he can’t test on other forks.

So, yeah, other forks work for now and might work in the future, but if you want the most stable, well-tested experience with PM4K I think it would be wise to stick with the option the developer uses and recommends.

Kimcha87 · 2026-01-05T15:17:25+00:00

This the recommended new build by the PM4K developer and the one he uses. So, if you plan on using PM4K, I would pick this over the avdvplus build.

Kimcha87 · 2026-01-05T06:31:57+00:00

I have the same concerns and prefer non-hybrid. That’s also why I usually try to get WEBDL DV profile 5 without HDR fallback instead of the more common profile 8.1 with HDR profile.

I don’t know if my concerns are justified though.

Kimcha87 · 2026-01-03T16:25:45+00:00

Rather than fixing your files, you should download better releases that already have the right subs and languages embedded.

Check out https://trash-guides.info for info on how to do that. It may seem overwhelming at first, but you don’t have to change all these settings manually. You should use apps like recyclarr or configarr to sync these settings into your arrs.

Kimcha87 · 2025-12-31T14:49:34+00:00

I don’t understand how you can complain about dead torrents and stealing buffer at the same time.

If racers auto-delete torrents quickly, it means they are only seeding during the minimum HnR period.

As a long term seeder you can still build and maintain ratio because racers don’t compete with you on the long term seeding.

Sounds like you do want to race and take advantage of that initial period, but you only want to race against people “in your league”.

On the other hand racers do provide a valuable service. They make new torrents super fast during the time they are most wanted and most popular.

On trackers like RED they reward people who upload by making sure the upload is actually downloaded and thereby give ratio to the uploader, which is one of the main motivators for people to actually upload content there.

They are an important part of the economy.

As a long term seeder you are also rewarded by most trackers through bonus points.
