iriver h1x0 - RTC (real time clock) mod

[poPFxv8V1]

Just wanted to report another successful RTC mod using the ds3231.

I departed a bit from the instructions though:

• The ds3231 is mounted upside up so the wiring is simpler.
• I used the pins as-is without bending them. Shorts on the pcb are prevented by a pice of Kapton tape (tolerates soldering temperatures).
• I soldered the NC pins to ground, as suggested by the datasheet. This provides lots of mechanical stability so I didn't bother to glue the chip down.
• I took Vcc from the serial port header instead.

Attached is a picture of the finished product.

Good job. It's good to see people still doing this. I still have not found a better 44.1 k recorder/player than the hP-120/140...

nice job

Did the mod last week (DS3231SN from maxim). It went so well that it was almost no fun at all

Another year, another successful RTC mod.  I used the DS3231SN and mostly followed poPFxv8V1's revisions.

Thank you to everyone who contributed their comments, experiences, etc.

Does anybody have Rockbox 3.8 with real time clock enabled for iRiver h1x0 ? I am not familiar with programing for Rockbox. Thank you!

You don't need to know how to program just to build Rockbox

Sorry, this topic is very old, but I was wondering if there still is a RTC-version of Rockbox available for those who doesn't do programming of rockbox? The link above does not work any longer. Could you please post a link here? Regards E

You may ask on IRC. There is a chance some dev with toolchain handy can build it for you almost instantly. Otherwise PM me and I'll build it for you.

Maybe an old thread, but not dead !
Recording from optical entry is so precious for me, but
I'm fed up with all those records on 2008-10-19 !!
I've finally gotten a Maxim chip
Before the electrical mod, I'm looking for a recent compatible RB version ...
Thanks for your help

As I said before, you don't need to do programming for Rockbox to be able to build it. And all versions are "compatible". It's just that the official builds have RTC support disabled, so the RTC simply won't be available.

Anyway, I've created a build for Rockbox 3.13.

THANKS  so many

I'm a simple old win xp user, and it seems very difficult for me even to install the cross compiler
I've updated my H120, (recovering all my presets !) ... and
I will post back, for (I hope) a successful mod !

[wodz]

running VM is not hard (and considerably easier then setting up cross compiler on WIN suitable to build rockbox)

Hi all

I made this mod many years ago and it worked fine. At that time, the H120 was my only mp3 player, then I was using it every day. Later I bought a smaller player with microSD card and I kept the H120 mainly for recording, via mic in or, for better quality, via optical in (by a Behringer DEQ2496 as a converter).

After some time, I found the battery flat, so I recharged it, but it went low more times. I suspected the RTC mod... Some days ago I noticed that after a full charge the player works for only a few minutes, then the HDD doesn't spin up. It tries indefinitely, until I reset the player!

Only today I opened the H120 for replacing the battery with another one I had from an old broken H120 and I measured battery drain:
HDD running: 580~680mA
Playing: 55~60mA
Off: 436uA (! with DS3231)
Off, after disconnecting pin 14 (Vbat) of the DS3231: 155uA.

A 1,3Ah battery, then, can last about 22h playing (a bit less, because sometime the HDD is running) and:

8400h (about 1 year) Off without RTC
2980h (about 4 months) Off with RTC.

Deep discharging damage a Li-po battery.
