So far what I heard back from the curator was that the vast, vast majority of what they have is there in physical storage and not scanned. I am awaiting to hear how one accesses the main documents in person, but with COVID it appears the campus will be closed for a long time with no chance of looking things up. However, the possibility exists for one of our CA friends here to be able to peruse them someday and perhaps obtain schematics for everyone.
I am in the midst of this exact project right now!
In theory, this is true. In practice, I have found that it would have been far easier, safer, and cheaper to just have purchased a commercial battery pack from Newegg. The 18650 cells can be very dangerous and frustrating to work with. If they are not handled properly, they will explode and catch on fire. (Don't ask about the melted battery pack on my workbench.) I built a spot welder to attach them together, but this cost almost $100 by itself. Theoretically, you could solder the batteries together, but with how reactive they are, I would not even consider doing this. I think the 18650 cells cost me $30, and a charger for the cells cost $10. If I had just bought a $60 battery pack, I would have been much better off.
Of course, I am having tons of fun figuring out how to do the project, and I am enjoying working on it. From a monetary standpoint though, I'm not sure it is worth it, unfortunately.
I hope to make a post about my battery as soon as I assemble a battery pack that doesn't try to catch on fire! I think it will be really exciting to use my Clamshell without being tethered to the power adapter.
