Currently we're waiting on a second revision protection PCB to be made. I forgot to include the revision in my last order, which means this new revision is probably going to be waiting through Chinese New Year. The order is in, 75% completion, and the new year just started. Previous PCB was...

The test PCB arrived, and we have success: connector footprint matches nicely. I'll be doing final checks on the cable design over the next few days, and will place an order for a set of 5. Then the design can be tested, and hopefully it works.

I have ordered a test PCB (not flex) which is the through-hole connector end of the cable, to verify that the footprint is correct. Once that arrives and is verified, I'll do one last check of dimensions and pads for the ribbon cable ends and submit for a prototype run of these cables. Also of...

The origin of this project was the mAcTX_LC which was released into the public domain on 68kmla. I downloaded the files and made one, but was frustrated that the use of a picopsu wasn't enough by itself, because the picopsu doesn't provide -5v. These files were lost in one of 68kmla's many...

I'd love to be making and selling these, but there are some problems. Only one of the 10 modules I assembled was functional from a flash storage perspective. On most of them, the DRAM works - but the flash for some reason just isn't having it. Some possibilities come to mind: * The PCB design...

As for the breaker popping instantly, the presumption is a short to ground. With everything unplugged (not plugged into the motherboard either), use your multimeter on resistance mode (or beeper mode if it has that) to check in the power supply for shorts to ground from the output voltage...

Looks like I need to do a small protection PCB revision. My solution for connecting to the selected power supply is to sit down over the output pins and solder in place. That connector footprint was off by a tiny bit and scrapes the side of the mounting bracket. Moved that, rotated a few...

I've had very good luck with the "Aneng" brand multimeters. Models 8008 and 9002. The 8008 was even reviewed by the EEVBlog, decent little meter. Note that I don't think they're trustworthy for high voltages due to lack of protection that you see in nicer meters. But for low voltage...

Did a test on the latest design (using my LC II), and everything seems to be working. At this point the mounting bracket is probably the final target for some tweaks before this is ready to go.

The Molex 26-03-4070 is the exact connector end you need, and the Molex 45570-3052 are the crimp contact ends.

Yes, the connector is through-hole on the backlit portable display cable. So it could be semi-easy to do with desoldering braid. Next step for me on this project is to measure the original connector and try to find something that matches the pin pitch. If I can find one of those, then...

On the subject of recreation display cables, I just pushed the flex cable design for the backlit screen upgrade into my PCB Designs repo on GitHub. Note that you need connectors and the ROM slot card for this to work. This is *not* the 5126 backlit cable, this is the upgrade for the 5120.

Will definitely post a picture here once I have one fully assembled and tested. There's not a lot of accidental contact surface on the top of these power supplies, which is pretty surprising. The exposed capacitor top doesn't test as connected to either positive or negative, and most of the...

The original BlueSCSI project is a fork of ArdSCSIno, with some code bug fixes to improve compatibility with later Mac OS versions. Mac OS 9.2 can be booted on a G3 using BlueSCSI, which is pretty cool if you ask me. This thread is for focusing on BlueSCSI variants which are available to use /...

This solution doesn't technically need anything at all from the original power supply. Not the case, not the PSU to motherboard cable, nothing. The new power supply doesn't really fit in the original supply casing, tolerances are just not large enough for it to be safe. Hence the printed...

Don't discount your work here, that mount design is miles better than the one I came up with. And you helped scouting for other parts.

If all goes well with the PCB testing, I could have 5 ready after Christmas. :) If you really want to do a large order then let's DM about it. The parts are starting to be in short supply (sigh, like everything else) and might need to be ordered in bulk from China.

This particular power supply is too weak for the IIci and similar. Another design would have to be sourced and designed around. I'm sure they exist.

After an incredibly long delay, this project is back underway. I've designed a protection PCB that has fuses and zeners to protect the LC motherboard, and it's on the way from JLC now. @GeekyBit has designed a very nice 3d printed mount for this setup. More or less we're waiting for parts to...

If you're interested in trying a hardware and/or software fork of BlueSCSI, I have kits available that support external LEDs. On my site, designs which are blue PCBs run the mainline BlueSCSI software. Green and black PCBs are running a forked version of the software on different...
