R3000 Indigo CR2032 hack

Unread postby jan-jaap » Thu Oct 02, 2014 2:27 pm

I had two Indigo R3000 boards run out of battery (the infamous 'can't set TOD clock' bug) in a matter of days.

The original batteries (Tadiran, Sonnenschein) are pretty expensive so I decided a CR2032 hack was appropriate. Here's the result:

Chyron Centaur Video option board mounted again. As you can see, clearance is not a problem.

Oh, and they work fine again of course. The CR2032 a somewhat lower voltage (3V versus 3.6V) but considering the price of CR2032 cells I don't really care if they last a little shorter :)

How long do you think the battery will last? Nice job though. By the way, you have some really high quality photos.

Nice. My soldering skills are totally inadequate, so I went out and bought the Tadiran (ouch!) for my Indigo.
BTW, you don't happen to have a spare keyboard for the Indigo?

How are you attaching the battery holder to that IC?

Two component glue. It's an SMD style battery holder so all it takes is a surface without circuit traces or via's. There are several via's in the PCB area around the original battery location so I opted for the nearest IC large enough to glue it to.

Last time I looked (and that was several years ago), cheapest 'genuine' was the Sonnenschein which cost me ~ 14EUR I think + shipping from Germany. Now I don't have to wait two weeks for a battery to arrive, I can simply got to the 'Action' discounter during lunch break and buy five CR2032 for one EUR, or close :mrgreen:

It's possible I have a keyboard, I'll have to look.

I brought out my Indigo yesterday which I previously swapped the battery on. Aaand the "new" battery was dead. I had of course used the more expensive "proper" part for the job... quite a bit of wasted cash since I haven't used the machine much. Today I'm buying a CR2032 holder and battery :)

Luckily I didn't solder the new battery in place.

Thanks jan-jaap for info and detailed photos.
