It's probably possible to do that. I've also thought of incorporating a mosfet or transistor somehow. The old relay part "TX2-5v" has a 4ms release. The new one "EC2-5NU" has a 2ms release. I doubt that will make a difference at all but who knows. I'd like to fix that but I really don't see it...

Here is the completed prototype, it will probably be 90% of the full design. It will also have a cover. I discovered through use that only one diode should be used. So I've made that adjustment. I've also got a faster acting relay on the way and I'm considering replacing LM 358 with LM393 which...

I can if it's just a single board, or maybe two or three. But I have a job so... But I'm happy o help for a little side money. I have everything in stock.

While I'm waiting for my custom pbcs and correct batteries for my pb100 battery, here is a test unit I made to fit in my portable, it seems to work well enough, it will switch into charge mode when the charger is connected and switch into operation when the charger is disconnected, the only...

I'd be interested in building a few but do you have a parts list and programming instructions or sd image? I saw the gerbers but maybe I missed the other stuff.

Those 1200 mah are just for testing purposes, Once I complete the design I can use much bigger cells, but obviously they will take longer to charge.

Where will you get the nubus chip?

I prototyped the circuit and it works! I adjusted the pot so it will trigger at 7.3v. I also ordered a 7.5v Zener diode so we'll see if that is a better setup.

So I've taken a few minutes to refine my idea, I was hoping the LM358 comparitor could drive the relay by itself but really I need a transistor.  I also added another diode to generate sufficient voltage drop for comparison. I'm considering how well the circuit will work if the comparitor is...

Yes, I did find a copy of the driver, do you need it? I searched for hours could not find it anywhere on the web, I only found it by running unerase on my scsi2sd.

You can reach out BBRAUN and he should be able to.

I didn't say they had no use, I said it helps assembly when attaching the waterblock to the CPU.

For a dual LCS, the don't do any sealing or anything, they just hold the water-block in place to make assembly easier.

Basically, I installed a powerview (a scsi video card) into the chassis of a classic II and with a long enough cable it works just fine. It is being powered off of the analog board and I then sideways mounted a scsi2sd .

Here's my latest project:  Classic II with internal video. Impossible? No way! If you believe it you can achieve it.

I have one in my 640, they are very fussy as far as ram, but they will take a 32mb sim.

Do you have the init installed? I one of these, I wonder if there's a way to download the roms without opening the machine,

Basically a CC board can't output VGA, a 550 board or a 575 Board can. What you're asking for is possible, there was even a company which made a video out adapter,

" Officially, the Apple Mac mini G4/1.5 does not exist, as Apple never formally introduced it. However, starting on September 27, 2005, Apple quietly upgraded the Mac mini G4/1.42 to include a 1.5 GHz PowerPC 7447a (G4) processor with the AltiVec "Velocity Engine" vector processing unit and a...
