after a long, deep dive into "how to manipulate a PWM signal for Dummies," i went back to the original board. Most of these LED controller boards are just the DF6113 "example circuit" with a voltage converter on the output. I spent a lot of time trying to figure out the DF6113 and realized my...

if i understand the question... this is designed to re-use the existing bosses; melt-push the bosses into the holes until they are flush to the face of the printed shim. at that point, the bosses will also be in contact with the existing case-wall. to wit, the shim is the same thickness as...

At last! My arm is complete again! thanks @fuzzylogic @alexGS this has been an excellent thread-revival.

i corrected a few flaws and produced a second board; REV1 has a better traces all around. The improved power rail revealed 16v was too much for the LED strip; the appearance of magic smoke led me to get a little step-down converter, turning the PowerBook’s 16v into 9v. The resulting 9v powers...

i feel this. I have tried to model it and given up, several times. your version looks good, the basic structure is excellent; the creepy double-parabola-thing is a little off, but sometimes in television we say, “Done Is Art.” I’m printing four of these right now tonight.

hey these are all great! thank you for your work!

no, there's nothing in any public depositary. that’s why i came back to this thread to ask about the friend.

yes sir, on the left and right over the hinges. (any lead on an STL...?)

typically gorgeous work by @jmacz for Part 922-0789 Display Access Cover i'm desperate for Part 922-0771 Clutch Cover, the little pointy bits that clip over the hinge-clutch

hey did your friend ever upload the PowerBook 500 Series Clutch Cover file…? I would pay cash money for the ability to print my own replacements.

hey, i'm happy to be part of the team. the $80 LQ94D041 was from china (some kind of New Old Stock); i got the eBay LQ94D041 for like $25 (that one came with a cable taped to it, obviously a pull from a nice person that didn't fall for eBay’s "automatic" pricing scam).

fantastic! share anything you discover.

(both extra SmartPortSD have been given homes.)

would you like a SmartPortSD? drop a line with an address, i will put one in the mail this weekend. Glad to be part of the community! —Æ

ooh i see you have the rare IIc mouse... but did you keep the box it came in??

i opened a test image into a hex editor and simply deleted the first 64 bytes. resaved & renamed, it opened just fine on the SmartPortSD. Thank for the assist... the 2mg documentation makes it especially clear & easy, the header is delineated by an intentionally blank space: 0030-003F: 00 00...

haha not allergic, i just don't have a way to run ciderpress? i will try renaming an HDV volume!

I wanted to make a SmartPortSD for my IIc. I previously mounted a FloppyEMU in the internal drive; that project turned out fine, but precluded use of the FloppyEMU as a SmartPort device without some creepy wiring. I decided to make a SmartPortSD adapter using erichelgeson’s instructions at...

looking around for ideas, i found an old instructable by a dude that made his own controller board. The board uses software to convert the analog signal to PWM for the LED—i think the code could flip the reversed signal. I am not skilled at electronics, but i know how to make things. I put the...

sunuvabitch... on some prior job, pastAE never reconnected the battery cage thermistor, it was just that simple. 180 works great and recognizes the new battery. i might have found that on my own--but i really appreciate the assist. folks, check the cables before you close the case.
