Welcome to the Rockbox Technical Forums!
But a touchscreen is IMNSHO worthless in a DAP, because without hard buttons, you have to be able to see the screen in order to effectively operate the device. This makes it a non-starter for visually impaired folks, or in situations where looking at a screen would be unsafe.
But having a touchscreen AND buttons for play/pause, vol+, vol+ and possibly next, previous and hold would be the best approach in my opinion. Most people are familiar with phones these days and a clickwheel from the older iPods is pretty complex and way less flexible than a touchscreen, even when the touchscreen is small.
This goes well beyond audio playback controls; It is a hard requirement that _every_ UI element be usable/available without looking at the screen.
If what you want is effectively a smartphone with more buttons, there are countless DAPs out there that are all trying to outdo each others by (badly) copying smartphone design (anti)patterns from the era of crappy uninstallable crappy carrier/vendor apps.
Small device - the smaller the better, but I would say that the maximum is 110x60x20mmreadable displayRepairable (incl. a replaceable battery)Hackable / develop software for itExtendable storageExtra buttons (next, prev, hold)
What bugs me the most on the iPod nanos is that they are so hard to repair and have low battery life. That's why I'm looking for alternatives.
I would be happy with a 3d printed case... at least for now. The sophisticated industrial production would be not a criteria, but I understand that this would be the approach rockbox would like to go.
Thanks for your opinion.
There are quite a few devices available right now that meet this criteria, including several still purchasable new -- The Eros Q/K (+ clones) clock in at 90x55x15mm, the xDuoo X3ii is 102x53x15, the classic ipods, and more. My daily driver is an original xDuoo X3 (106x45x14) which even has dual SD card slots.
It's also purely internal-flash-based, which means it _will_ eventually fail and become a (crappy) paperweight. That's one of the best arguments for the HDD-based iPods; the spinning rust can be replaced with a CF or SD card, easily swappable when it fails.
3D printing is awesome for prototyping, but it's horrendously expensive (and slow) for serial production. (And you have detail/tolerance/finish limitations which can cause problems for things like buttons, which is a really big deal here.It's actually pretty straightforward to build a prototype DAP using (eg) an SoC devkit and a protoboard; but to build your own PCB you need to already have the enclosure.

If not, is it possible for me to add the chip manually some how?PFB29-12AL_1438It appears to be by spektek; here were the product specs I found.https://www.spectek.com/pdfs/SPECTEK_4GB_NAND_m40a.PDFIt is a 16GB SD card with two of these chips and a microcontroller (So 2x8GB cards).Thanks.
