i just snipped the fuse off entirely. does yours have a switch?? i did not add any diffusion to the LEDs. i have rarely encountered brights spots... i wonder if lightly sanding the top of the LED would add just enough diffusion? i will try that on a build. (i'm playing with a powerbook 1400...

the LED-converter strips and voltage booster boards are all pretty much the same (product links above have rotted, there links are LMGTFY) there's not much more to the install than is shown, but feel free to ask questions to clarify anything: Find the solder points for ENA, GND, VCC, and...

holy cow, pardon me, i copypasta’d some web misinfo... the Sharp LM64P791 is a 9" screen.

howdy friend! the powerbook 10 LCD is a Sharp LM64P791, 10.4" LCD at 640x400pixels i can't get to the bare LCD right now, but the bezel is 193mm x 121mm

i have done (5) iBooks of a couple different generations; i don't use them everyday, but every time i use them they are solid and bright: no drift, no flicker. It's been a great mod for my interests. I cannot report how they run off a battery, and i would be interested to hear about that. it's...

i will play with that, the OMRON R2DG-38 is really just a fat little servo itself... (but i'd still love to understand the Auto-Inject mechanism...)

i had one non-working drive that i decided to dismantle: i couldn't figure out how to just get the mechanism separate. Worth another try, but drives are limited. the bigger problem is: the servo just doesn't have enough torque to push the existing metal cage around. It can flip a wee switch...

the board is dead simple; i asked a friend to throw the code together, “sure, that sounds easy.”

I have been working on a Mock Floppy Drive. My goal is a drop-in unit with a Floppy Emu at its heart, albeit with the screen and controls moved to a fake floppy disk that pops in and out like a real disk. There is no need for this device, it solves no problem, and might be completely...

it is possible with off-the-shelf parts. i went round-and-round and finally got to a simple solution. See what you think. —Æ

inspiration.

hot glue is for decorating construction paper! might as well repair with glitter elmers... 😁 i use solvent glues from my prop making days, the type you have to use outside... in the wind... two towns over. aww, i've done more with less (ask me about the Quadra 605 case, might as well be made of...

I picked up a 575 on a trip—literally picked it up, i brought it back as Carry On Luggage, god bless the god humor of United Airlines. The little beast survived the trip and is working great; i have already bumped up the RAM & VRAM and swapped the processor to a full 68040. Next up is an...

(I do not have a Titanium G4 nor can I find any reliable pictures of the inside. Post something and maybe we can poke around.)

i do not have a Lombard to play with, but i pulled this picture from a search: the inverter board appears to use the LT1182, same as the Powerbook 1400 (the Wallstreet uses LT1184, functionally identical with a couple different inputs). I have been poking around the 1400 inverter board for...

yes, as long as you have the correct Interconnect-to-Display cable, you can have an Active Matrix PowerBook 520c for the LQ94D041 Display you need the cable that says SHARP COLOR TFT (active matrix), part 821-0026-A / 632-0017-REV.A everything else--inverter board, interconnect board...

The 540c display can suffer from failed capacitors; i have replaced capacitors on a couple screens, including a new-old-stock that i purchased. It's an inexpensive treatment, certainly worth a try. @3lectr1cPPC maintains the most excellent reference site. if you want to purchase a replacement...

it's incredible in idea, but i’m not 100% sure it works. Turns out the circuitry is weird, like most PRAM batteries only charge if there is a functional battery charging in the PowerBook--no charge to the main battery means no trickle-charge to the PRAM. I've tried this PRAM replacement board in...

i have installed this shim into three PowerBook 1400cs. I don't doubt it could use some finesse, a half-a-millimeter here and there that i was too deep in to notice, "meh i'll just push a little...”; i appreciate the objective assessment. If someone can adjust the STL--and maybe someone install...

this is fantastic—i couldn't have commissioned better work; i'm thrilled to be part of the process. thank you for giving this to the community. (@BinaryGrind please share your remix!)
