Clock Cap Replacement, Best Alternative In 2020?

Recommended Posts

Time passes by, so does the life of our OG Xbox Clock caps (if they are not removed already) but also technology in cap replacement options.

So I wonder what the most

Reasonable/

Convenient/

Easieast/

Safest/

Cost efficient/

Clock cap replacement of today could be?

I know some people are not bothered without it and some people (lile myself) that would like to have it working :)

Through the years I read that it can be everything inbetween replacing it with a

1F 2.5v original spec AeroGel cap,

10F 2.5v AeroGel for longer working time,

a CR2032 battery socket with 1N4148 diod in series to prevent REcharge, which would not be good,

2.4v NiMh rechargable battery.

 

My idea, not yet installed and tested, is to solder an AAA batteries socket with two 1.2v 800mA replaceable batteries to the old Clock Cap points and try to fit it in somewhere. The batteries gives 2.7v fully charged and would (theoretically, if the Xbox can give them enough charging) give more than enough unplugged power time and it would all in all cost around 5$.

 

So now in 2020, what is your clock cap replacement (ideas, pictures, pros/cons, results)?

As the clock cap was only able keep the time for several hours replacing it is not really worth it..

All my Xbox's get the time and date set/updated via the internet on power up any way.

Yes, that's true, did that sometimes through XBMC, but since I move my console from room to room sometimes and don't want to drag an 20m network cable back and forth.

I am just a sucker for original/stock , so I would like to just have it working as it was originally intended, but with upgraded capacity with more modern components, since I just move it sometimes without plugging in the power cord and it stays there a couple of days or a week.

I don't know if there would be sufficient power for recharge to use NiMh AAA batteries, otherwise I seen that there is 100F-500F 2.7v caps, so I may give those a try.

I don't think the circuit that's for the clock cap would charge NiMh batteries unless the Xbox was powered on for days possibly weeks even.

The clock Cap was only ever for short term time and date retention any way

Your best bet try a 2.5F 2.5 volt cap I don't think the circuitry around the clock cap would correctly charge any thing bigger or like me fit a network port in every room.

I have a 1.6 XBOX (I call it SpideyBox) with a bulging clock capacitor... 😞 and looking for a decent replacement from digikey our mouser.  Located in the US. 
Looking at Digikey part 
604-1034-ND looks like it might be viable?

That one will do the job fine.

It seems like

283-2776-ND

604-1034-ND

604-1149-ND

should work.

I wish we had those prices in north of Europe :/ you can take those prices x5-6 for one of those caps here.

 

Well, sorry to say, but I am not going to re-wire the house to be able to move my consoles around, and I don't goint to drag a miles long ethernet cable if I take it with me to some friends.

The 1.6 consoles won't even start unless the clock caps are in place, so I just wan't to stick to the topic, what the best / most effective clock cap replacement could be now in 2020.

well, why not give it a bigger capacitor?

In theory you could put a 10farad cap in place of the 1farad but would take 2 to 3 days to fully charge if it didn't damage the charging circuity with the inrush current.

I remember reading in some forum, I don't know if it is on one of those that are lost in time, that 10F seemed to be popular value fore those who replaced it back then, could keep the time for a week or two, if it is chargeing when the powercord is connected, 2-3 days would pass on by quickly.

This is just a big theory,, but I wonder if there exists a small 5v driven 2.4v chargeing PCB that could work like a controller with positive output switch/relay? Instead of that the Cap circuit would have to try to recharge the batterypack.

Then there maybe wold be the posibility to solder it to a 5v line in the console that recharge a small 2.4v NiMh battery pack or equivalent while powercord is connected, with the positive from batterypack switched off to the Cap connector positive point as long as the chargeing controller PCB has power, and when the 5v is turned off it switches to let the positive from battery pack to the Cap connector positive point?

I don't know if the curcuit on the MB would handle to have a 2.4v battery pack connected to it via the Cap connector while a batterypack is being recharged.

I just overthink simple things, but that would be an overkill cap replacement that would last for weeks and weeks, and keep thoughts of leaking cap and trace corrosion miles away for some years.

The only cons I can think of is that NiMh don't seems to like to be stored uncharged for a period of time.

      Good afternoon everyone.
      I'm putting games and emulators on my Xbox, I downloaded coinOPS and it has a lot of cool games on it, specially arcade games for a lot of hours of fun.
      Now I'm looking for an emulator of PSX and N64. I tried the PCSXBOX_v.23 with Vigilante 8 and Vigilante 8 2nd offense and it goes really, really slow.
      I changed some parameters of the emulator and there isn't improvement in the emulation.
      Anyone knows a better emulator or the correct configuration to play these games?
