I got a good deal on a PowerBook 540c "for parts", i meant to strip out a couple pieces, but the screen is immaculate and the case is good (hinges still strong!) so, of course, i set about trying to fix it. (i have a box of 500-series pieces, I figured i must have whatever the machine needed...)...

well now i’m imagining an entire 1400 case milled from aluminum...

that's an interesting idea; the piece right now is not a simple profile, but feel free to adapt it--maybe several thin layers of metal put together could fill the space...

hello, yes, @3lectr1cPPC called it: i have a Prusa MK2.5 and do all prints myself.

i've pulled apart several wallstreet & PDQ and they're functionally identical inside; i don't know about the inverter board in Lombard & Pismo, but i honestly bet it's the same—i hope someone will undertake the same mod and share pictures.

I love my PowerBook G3, and the fading CCFL was not doing justice to its beautiful 14" Screen. I have a couple "parts" machines, so i got out the multimeter to see if I could get an LED strip in there. (This mod was a quickie while trying to part out another project, but this went so fast & easy...

includes a floppy! that's some top shelf service right there, someone that knows their market.

bonus, i was missing one foot, so i modeled a replacement. The PowerBook 100 feet are actually fantastic tiny machines, two parts in separate tracks that flex and expand to extend the feet. Standard disclaimer, "artist not engineer" and "please remix and share.” I printed from PETG for...

it does NOT turn off; turning it all the way to the left just reduces it a little, like from "brilliant" to "ambient"

i traded parts with @360alaska to get an excellent screen; i transplanted my LED-CCFL replacement and got it all in place, and it’s gorgeous. apparently i accurately rewired everything, because the brightness actually does work. quick demo video attached (ignore that little freakout when i...

hey nice work! that looks great, thanks for sharing pictures.

the contrast control is independent of the inverter board, and still works great--if anything, it seems more responsive under the more powerful light. according to the block diagram, the contrast pot connects directly to the lcd via the interconnect board. (seriously, the simplicity of the 100...

i printed a mock-CCFL tube with a 2mm groove to hold the LED strip in place. i also made a little "tray" to replace the inverter board. (I sawed the connected off the LED controller and squeezed it in.) I wish the picture communicated how glorious this looks. Except: my attempts to clean the...

i would love a solution for other 100-series machines, i have a PowerBook 180 that i adore. But the 100-series screen controllers are quite different, and i cannot find any schematic to provide insight. (I was encouraged by how simple the PowerBook 100 boards were: so minimal, i figured i might...

A friend gifted me a dead PowerBook 100. It was only mostly dead; all it took was replacing every capacitor, now it works fine. The screen is predictably dim. As part of the repair, i took the LCD apart: the little CCFL has plenty of crusty black inside its ends, i’m sure it doesn't have much...

…

i am but a vessel… please post your results! i expect it will look really slick.

this is a great idea, non-destructive edits are best. the connectors on the Meanwell board are JST VH, get some maybe with leads already on and splice onto power switch etc.

Well there’s the difference: the lower mounting tabs are about a centimeter off. Doesn't matter much on the left; on the right, i fixed it with a dremel. (The bezel is tight enough, the screen stays in place just fine without the lower mounts.)

the parts have different numbers in the tech manual, so i expect those are not interchangeable. i used this LCD and the cable from a 1400c to upgrade a 1400cs--so the motherboards are fine with the change.
