    Rebuilding a Pismo battery

    Started capacity testing cells numbers 13 - 16 this morning. A bit of a slow process as the default charge/discharge rate is only 300mA. Previously charged batteries do indeed show some variation ... both in capacity and internal resistance. The replacement Seesii battery spot welder has been...

    Rebuilding a Pismo battery

    Replacement battery welder showed up the other day, thought it was something else and didn't bother to open the package until today. It's now on the charger. Tenergy Battery charger showed up today. It's now running a capacity test on the first four 18650 cells.

    Rebuilding a Pismo battery

    Have checked initial voltage on all of 18 cells. They all pretty much read 3.48v as delivered with a couple flicking up to 3.49v, or down to 3.47v, for a moment before coming back to 3.48v. All cells were sequentially numbered and marked with a Sharpie with their initial voltages. The cells...

    Rebuilding a Pismo battery

    Referencing these from another thread since this is probably the more relevant thread: What did you do to your Apple/Mac today? What did you do to your Apple/Mac today? After some back and forth with the seller (having to do with where the replacement welder would be shipped from and how -...

    Radius Video vision card with studio and RAM upgrade.

    OP, The VideoVision breakout bar that I have is surplus to my needs since I have the VideoVision SP upgrade (... which, truthfully, I'm not using either) If you are interested drop me a PM.

    Radius Video vision card with studio and RAM upgrade.

    Think it supports higher resolutions ... a max of 1152 x 870 @ 256 colors from what I'm reading/recall. Not quite accurate ... I believe the card can be used to drive a regular computer monitor with a suitable cable, as above. In terms of video capture and output, there were three options...

    Pismo G4 550Mhz Upgrade, overheating issues

    Unless of course you position the unit such that it's exhaust is blowing into the Pismo's intake port on the right side next to the DVD/hdd bays. It was delivered just a little bit ago and I have to say I'm fairly impressed. Feels pretty hefty, nice packaging. Comes with 31" long USB-A ---->...

    Pismo G4 550Mhz Upgrade, overheating issues

    I do have an extra DVD drive from the spare parts Pismo. Might have to have a look and disassemble that and see if it’s practical to repurpose that as removable fan housing. Would need to see if the incoming airflow could be routed to the processor card area. Might well be possible to...

    Pismo G4 550Mhz Upgrade, overheating issues

    Yes. Will have to look at the values in my kext here though and see if they match what @greystash has posted there. Possibly. Right. I have identified the solder pads on the power pcb that the power connectors for the DVD drive and batteries connect to. What I have not done is probe those...

    Pismo G4 550Mhz Upgrade, overheating issues

    Just to be clear, the Pismo was never fanless so far as I know ... always had one. And one could certainly do quite a lot ... without causing the fan to come on. But that's likely due to the high temperature threshold Apple set before the fan would activate and turn on. Like I said...

    Pismo G4 550Mhz Upgrade, overheating issues

    As the thread title suggests I have serious overheating issues when the processor is under prolonged heavy loads. This occurs when the computer is working on processor-intensive tasks of long(er) duration (>30 minutes) The issue appears to be entirely due to the fact that computer's fan will...
