Pacemaker big battery replacement

Old Pacemaker with new 1500mAh battery

Thanks to our excellent lab technician Elizabeth. I bought a 3.7v battery to replace the one in my 2nd pacemaker. I previously had replaced the 1.8 inch SSD with a SD card, so knew there was more room in the pacemaker case.

I had hoped to buy a very thin battery which I could slip under the SD card but I couldn’t find one with a higher capacity than 500mAh. Instead I looked for the highest capacity I could get which fit into the same battery space. I found a few 1100mAh batteries but then finally found one which was 1500mAh and the same voltage.

I unfortunately couldn’t didn’t quite get the right size, I was about 1-2mm’s off in height. The only way to make it fit was to remove the brackets which protected the old SSD/HD from the battery. As there was no drive anymore I decided its ok to remove them. With them gone, I could shift the battery over a bit and fit it in.

With some great soldering from Elizabeth, I was able to get everything back in the case and screw the whole thing together.

Looking forward to doing similar with my main pacemaker device, maybe?

Pacemaker device finally upgraded with a SD card

This time while upgrading the Pacemaker device it was a success. Its a strange combination because I got a Micro SD stuck in a SD card which is stuck in a Compact Flash card which is connected to the Pacemaker device with a tight Zif cable.

Its not so tight as when I had the 1.8inch SSD but the zif cable is still not in the best position it could be if it was shorter, as I noted on my original pacemaker device.

Next stop is to upgrade that battery. I’m thinking about a larger flat battery which can lay on top of the compact flash holder?

Upgrading the pacemaker device with a SD card, not this time!

Its a short story (not in effort and time). I tried it after a colleague suggested it instead of SSD a while ago. I tried it but found the card reader the Kalea Informatique adapter, didn’t support SD cards over 32gig. The description said 64gig but everytime I restored the pacemaker firmware it would only format to 32gig. Even using Gparted (like partition magic) to extend the Fat32 partition caused the pacemaker to no longer be accessible by my laptop (it comes up as generic Linux storage device).

I haven’t given up, I’m returning the Kalea adapter and have bought a Kalea adaptor converter but the compact flash version. Yes in short it would be a┬áZIF LIF to Compact Flash to SD card.

Hopefully this will actually work

Upgrading the Pacemaker’s hard drive

2013-05-04%2011.16.39

Been doing some of the odd jobs I’ve been meaning to do.

One such task was finally buying the right SSD from Amazon and replacing the old Pacemaker hard drive.

I was looking at the pacemaker forum where someone posted how they replaced their original hard drive with a Solid State Drive (SSD). So after much time I decided to buy the Kingspec 1.8inch drive from Amazon. Its only 64gig big but to be honest with the old drive I was only using 32gig anyway.

For those thinking about doing the same theres a number of things to bear in mind… You need a ZIF 40-pin SSD/PATA Solid State Disk (MLC type). Zif is the connection and its a ribbon connection like you see on motherboards.

Everything was pretty straight forward till it came to putting in the new drive.

Oh crap I ripped the ribbon!

As the forum post wrote…

DO NOT MAKE THE SAME MISTAKE I DID AND RELEASE THE ZIF RIBBON FROM THE ACTUAL PMD MAINBOARD ITSELF! IT WILL MAKE YOUR LIFE EASIER IF YOU LEAVE IT IN PLACE AND ATTACH THE NEW HARD DRIVE TO IT!

Well somehow I started to rip the ZIF ribbon when moving the drive about and so I was forced to use the longer version which came with the SSD. That extra length is a real pain as you have to fold it without breaking it when putting the device back together.

PATA ribbon in the way

Carefully I put the whole thing back together and as the post says, it came on and complained the device needs a firmware update. After doing that and loading all the music back on to the device from the pacemaker app I was back in action again.

To date everything has worked and the battery life is much better than with the hard drive. Things seems a little more punchy too, so menu updates, etc are a tiny bit quicker (but it was already pretty quick). Can’t wait to put in the new battery and boost that up too.

Hard drive restored

As you can see in the photo, I’m planning on replacing the battery at some point. The battery seems easier but will need some soldering as the one I got has no connector. From the forums it looks like the battery is a 3.7V 1600mAh lithium battery Polymer while the one I got from ebay is a 3.7V 1000mAh lithium Battery Rechargeable Polymer Li-Po. The hope is that my pacemaker battery which back in 2007 lasted on average about 5hours but only last 30-40mins now will jump to about 3-4hours with 1000mAh.

Pacemaker hard drive problems

Pacemaker fixing

It was always going to happen…

A portable dj device which I tend to walk around with while mixing to myself. I accidentally dropped while in the middle of recording a mix. Ever since its been acting a little weird and worst still crashing mid mix.

The song which seems to trigger the hard drive to start clicking happens to be JS16’s Rosegarden 2.0 ironically.

Anyway after 6+ years of use I think its about time I made some upgrades. The great thing about the pacemaker is its pretty much a Linux PC. So a lot of the upgrades should be pretty simple. Of course the pacemaker community can help with everything

First the hard drive, going with my wired, tired, expired. Its time to move to a solid state drive. I only tend to use about 30gigs of my 120gigs of pacemaker storage. So I’m thinking about getting a 64gigs or even 32gigs… The drive as you can imagine is needs to be a 1.8inch drive, and needs to be ZIF/PATA rather than SATA. According to the post there are two different ZIF connections 0.2 mm and 0.3 mm, although its not clear which one I actually should get.

While I’m doing that I might as well do a replacement on the battery which lasts about a hour right now. Although I discovered I could charge the pacemaker over USB while using it if the USB is pure power and not a computer. Of course I also have the AC adapter but nothing beats having lots of battery power.

This looks to be better done in a workshop?

Thanks goodness the Pacemaker isn’t made up of custom hardware bits…
