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...

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
