Nice project. $249 seems a bit high, but I guess it’s like the Fairphone, they can’t save as much as the large manufacturers do.
Holy f*** $250? Wow well it is not for me then :(
I’m genuinely curious if someone’s published a BoM cost breakdown, I’m wondering if there’s a couple of super high tickets items in the like the scroll wheel and custom PCB cost.
The cost of the scroll wheel cannot possibly be more than 10€ and the pcb cannot be more than 1€ battery is about 4e and display can be 7-8, chip is 2-3e and passives, connectors etc brlow 5. The manufacturing costs of the thing are likely below 40€, even in small volumes. Assy costs are probably about 20% of the total.
Part of the high cost may be investments in moulds for the casing and r&d cost.
Yeah, I took a bit of a poke last night, there’s a couple of ICs in there that could add up a bit I guess, but even being generous I wasn’t getting much last 80.
The cases I saw had the look of a 3D print about them. Original goal seems to have been around 10000, so maybe they’re amortizing the r&d across 40 units, little bit of profit and then went and sold 400 of them - nice win for them if so!
To make it clear I don’t begrudge them their profit especially as they’re open sourcing the thing. The concept and high price has got my creative side going for sure, an ESP32-S3 pro dev board looks like it could handle an sd card, screen, MP3 decode and output to an I2S amp all by itself + BT headphones and WiFi track downloading and battery charging. Slowly talking myself into building a portable podcast machine.
Hey, one of the people working on Tangara here. The case we’re shipping with will be CNC’d polycarbonate, though the same design also works for home 3d printing.
The price is a lot of little things adding up, and we want to be able to do smaller runs post-campaign and still have it be worth our time. I also wish it could be more affordable, but that’s how it be with indie electronics.
Good luck if you do decide to make a little podcast machine! Just be aware that afaik ESP32-S3 can’t do bluetooth audio (see: https://github.com/espressif/arduino-esp32/issues/8675).
Thanks, really appreciate the feedback! Really good luck with the project, love seeing these kind of devices making it into the wild. Yeah totally appreciate the nature of indie electronics/manufacturing in general and your work totally makes it easier and more approachable for a lone wolf like myself to churn out something functional!
Thanks for heads up on the BT audio, my little investigation the other night lead me to the datasheet for the ESP32-S3, the list of peripheral options is amazing, I’m sure I’ll figure something out!
Thanks again and good luck with the project!
It’s a project by an Australian team, so one would assume two things:
- It’s in Australian Dollars.
- Australia has experienced severe hyperinflation overnight (or earlier today, for many of us reading this)
Can I get some sauce for #2? News says nothing of it
It was a joke.
I think it has something to do with Taylor Swift
It all has to do with Taytay Swizzle. WAKE UP SHEEPLE! She will be crowned Empress of the World by chief Illuminatus Warren Buffet and the antiChrist Catholic puppet Joe Biden during the Super Bowl halftime show! Only Trump and Dildoboy Nugent can save us!!! /s
The only source is the absolutely bonkers price – that’s why it’s an assumption.
In all seriousness, if I were to release open source hardware and software, I’d charge a price like that to ensure that my time would be reasonably compensated for what’s clearly going to involve small production batches of hand-built-in-the-first-world items.
What hyper inflation? I think you need to check your sources mate.

It’s a neat project. Costs as much as an iPod :P
Hopefully people take the source and release a full walkthrough on doing this with an entirely off-the-shelf design. I’ve got a full electronics workshop and two 3d printers and would LOVE to assemble my own music player with open source designs.
Brings back fond memories of rockbox on my sansa.
Rockbox was the shit.
Breathed so much life into my iRiver. And I always had to defend the thing: “it’s older than iPods! It can’t be an rip-off”
Rockbox *is…
It’s still going.
I use rockbox on a late ipod classic. I find it a very good listening experience, but I am interested in switching to open source *hardware
I’m assuming you mean hardware? Because Rockbox is already FOSS (GPLv2)
That’s wild!
Now you too can play Doom on the worst screen imaginable!
With the worst controls imaginable to boot :)
New speedrun challenge!
Ayo that was amazing on the Sansa Clip+.
oh shit rockbox I had forgotten about that
This is insanely priced, particularly when you see that it literally loses on everything but battery life compared to the original iPod 5gb, let alone the Classic.
Not quite. It has 1TB sd card storage. That’s far, far better. And it has wifi and USB not just FireWire. Ram is less sure but how much ram do you need for playing tunes?
Where did you read 1TB? The webpage says it supports up to 2TB but doesn’t say it ships with an SD card.
My bad. 2 TB.
If you have chrome browser JavaScript applet as the media player backend, terabytes.
Aha, I did indeed miss the “external storage” row—mostly because it only uses the “Tb” acronym quite late in the description. I think the difference between Firewire and USB-C is minimal? (ie they are both “fast enough”) but I guess having wifi is a step up (although I always still plug my phone in to transfer music at this point so…)
Has anyone checked out prices for refurbished ipod classics? $300 for a 20 year old mp3 player! Insanity!
Edit: looking at the specs for the Tangara… 16MB of internal storage??? Uhhhhhhh… I guess the intent is to use an SD card.
Are these “refurbished” or “updated”?
An OG iPod in decent shape with original specs is cool from a collectors point of view, but even then $300 sounds steep.
But if you slap a modern li-po and higher capacity modern flash storage, maybe a haptic module? Dude. Now it’s a highly functional piece of nostalgia.
20 hour battery life of use is actually far better than I thought it would be. Wonder what the pi equiv build would bu
The Pi in any form is a much larger system with a whole lot more clock cycles, larger architecture, and more peripherals like a full memory management unit, graphics hardware, etc.
On the flip side IIRC most ESP32’s are 210MHz and just dual core. It is microcontroller versus microprocessor, so probably 10× less power or more.
A Raspberry Pi Pico would be sufficient for this. It uses the RP2040, which is comparable to the ESP32, minus the WiFi.
Actually not really. The pi pico has no functional, good low power states currently developed. That is essential for a mobile device. A pi pico would simply drain the battery in sleep mode very quickly.
Tons of MCUs could do the job. Some STMs would also be good for it. The pi pico is more focused at non-mobile applications though at the moment like a very cheap general MCU for things that are USB powered or mains powered.
For something like this, you would use the RP2040 chip rather than the whole Pi Pico module. The RP2040 uses 180µA in its lowest power sleep mode and the flash and regulator will use a few more microamps. The battery would still last for over a year in standby. Of course it could just be turned off when not in use. Without an operating system, the boot time should only be a fraction of a second.
The ESP32 uses 800µA in sleep mode if you want to retain the memory contents or 10µA with only the RTC memory retained.
A low power STM32 would use orders of magnitude less power in sleep mode than either the RP2040 or ESP32 though.
Yes, I know. I have designed with the RP2040 and 180μA is extremely high power usage for deep sleep mode.
The ESP32 has far more sleep modes than that that each use different power, you are just talking about its light sleep: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/sleep_modes.html
You are comparing the deep sleep of the pi pico to the light sleep of the ESP32 where the coprocessor is still running. The rp2040 light sleep mode consumes 7mA. It is literally orders of magnitude different. https://learn.adafruit.com/deep-sleep-with-circuitpython/rp2040-sleep (they only did light sleep.mode because deep sleep wasn’t even available)
As far as the professional chips, they cost on average far more for less and less sleep gains. (A lot of the L series of stm is like 15€ per chip)
You would definitely use deep sleep for this as you would only wake it up to start using it with a button press. Whether they would use light sleep or deep sleep, there is an order of magnitude difference in sleep power consumption.
That’s actually so low imo. It just plays music and doesn’t connect to internet right? Should last for like a week at least.
20 hours of playback. Not 20 hours of idle.
Hmm if it’s 20 hours of constant playing then that’s much better
It needs a serious optimization. iPod Nano 7 lasts 30 hours with a 240 mAh battery. So with 2200 mAh, it should last like 10 days at least.
Ipod shuffle lasts 12 hours with an even smaller battery
It has a 150 mAh battery, so even with Shuffle’s optimization level, 2200 mAh should still last more than a week for Tangara. I gave Nano 7 as an example because it’s what I have. Of course I’m not expecting Apple level optimization but they can do much better. Otherwise 2200 mAh is an overkill for such a device.
Looks like the first iPod, the brick.
It sounds like that was intentional.
Is that a click wheel? I’ll be surprised if apple won’t sue them over that.
Well if Apple owns IP on it, I guess it would have to be a patent. The hardware would be quite different I guess, so would be a design patent with a max of 15 years from 2001 when the first iPod was released.
I’d guess Apple wouldn’t sue, for a design out of patent (so no obligation to defend it) and that they don’t even use anymore. (I ANAL)
Cool cool cool. I miss my old iPod with the click wheel, so I hope you’re right. I’d love to get an open-source hardware device using one now.
It would be interesting to use one and see if it feels the same. The original iPods had this very specific feeling to them. If it was replaced with say a glass capacitive circle or it if had different haptic feedback then it would feel quite different.
Capacitive touch wheel.
I haven’t seen a device that takes full sized sdhc cards in at least a decade.
They got $136k funding from an original goal of $10k. Did it go to their head?
Listening to music like it’s 2005 all over again

Genuine question : Why use that instead of storing your musics on your phone ?
I prefer an MP3 player over my phone. Here is the one I use. Why I like this one:
- Dedicated device designed for music.
- Hardware designed to play high quality music. (Think using Ubuntu vs Ubuntu Studio for music production)
- Dedicated buttons instead of all touch screen.
- More options for integration with other devices or systems
- No distractions. Phones nowadays demand our attention for every little thing. Every app, no matter what it is, has notifications.
- The Bluetooth is better.
- You can literally hear the difference in the quality of the music if you use good quality headphones/ear buds. The same song, same file, will not sound the same if it’s a good quality FLAC.
My phone doesn’t have a 3.5mm headphone jack.
Such courage! /s
While I use my phone for music I can certainly see some advantages:
physical buttons
smaller and lighter
less distraction than a phone
cheaper to replace if stolen or brokenYou can replace your phone with dedicated electronics, which has some advantages, such as better battery life and generally better performance. Like I bet this thing has a better amplifier than a phone has.
And phones have their downsides. They don’t last as long and are expensive. Privacy issues. And can be too stimulating and intrusive. For example sometimes you just need to know the time and before you know it you’re emailing someone.
When I go hiking I can just as well take a dumb phone, a GPS and an mp3 player with me. Maybe a camera too.
I have a shuffle just for running.
Having something that doesn’t connect to the internet makes for a better device in the long run. Plus, as others have mentioned, less distractions.
I will always prefer my iPod Mini with extra storage, new battery and Rockbox like this guy did, and the reasons are:
- better overall build and audio quality
- way cheaper (70-80$ vs 249$)
- better software support (Rockbox is FOSS and has been going on for ages and it’s not gonna stop)
- it actually upcycles old hardware instead of buying new devices and creating more e-waste
- nostalgia value +100 points
Will buy for the Opus audio codec support alone.
