FWIW, the only special gear needed for casting other than a 3D printer is the vacuum chamber, but you can get those quite cheap. I got this tiny little one for about $40 which was a good size for making a dixie cup of polyurethane for casting. A new pump for that would be about $60 but I'd guess...

Last year I did some experimenting with recreating rubber feet. I used an SLA printer to make mold positives. Then cast those into silicone negatives and cast polyurethane parts in those. The benefit is that you end up with parts that have an original look and feel. But it's a lot of work and...

This sounds a little different from your issues, but maybe worth checking D12 just in case. https://www.eevblog.com/forum/repair/metcal-mx-5000-repaired-for-not-heating-up/msg1343323/#msg1343323 Also this thread mentions there's a hidden factory reset you could try. Sounds like you need to hold...

Since I don't think this is documented on the site yet, here's the list of caps for both the logic and power supply boards on the StyleWriter 2400 printer. In my case they were all fine, so I ended up not replacing anything, but good to have the reference if something fails in the future. All...

I’d keep testing components downstream from that port. Maybe a leaky diode or bad transistor? Also it’d be good to make a post about this on EEVblog forums as well since there are some folks there familiar with repairing Metcal stuff.

Does it do that with any cartridge installed? I had a cart go bad and it would similarly ramp power then say something like “incompatible cartridge”.

It looks like a JST connector of some sort. Maybe XA or one of its variations? You can browse through their wire to board catalog here which is sorted by pitch to find the exact match. https://www.jst-mfg.com/product/index.php?type=2&key=1&page=4

Fo years I've been using a generic 10 liter ultrasonic cleaning tank I got from Amazon. It's been fine, but a little cramped for some boards and its build quality is mediocre. I'd heard of Crest ultrasonic cleaners via Louis Rossman's videos and they seemed to be very well made and performant. I...

Beautiful photoshop work. Check out that hand!

I was recently repairing a backlit portable that does not have a hybrid board. In that area however was RP201 which had multiple rotten legs due to capacitor leakage nearby. Unfortunately, that SOIC resistor pack is custom to Apple, so there's no direct replacement. In my case, grinding back...

That's a noble crusade. We get used to the quirky nature of this stuff, but it can be daunting to someone new to the hobby. Nice work!

That's super handy. The 'What Now?' steps are a nice touch too. Do you plan to have it support any other formats like .hqx?

I recently got a PowerBook 3400 that would chime, then chirp and make some pretty crazy siren type sounds. The sound would go away and the screen would light up if I disconnected the hard drive. I assumed not enough power was getting to the HDD, so recapped the DC-board and MLB (just three caps)...

Nope it didn't leak.

User induced gore since I was curious what was inside of these square batteries.

BTW it looks like the older Blue Ring tester kits are maybe no longer being made. There's a more modern tester based on a microcontroller for sale here, though I can't vouch for that site since I haven't ordered one myself. https://evbesrmeter.pt/ring%20tester.htm YouTube video demonstrating...

What happens if you give it a tap when powered on? If you get a flicker of video maybe you have a broken solder joint. Have you already checked/reflowed the large joints like those on the FBT?

FBT coils cant be tested with a typical multimeter but can be with a ring tester. Search for blue ring tester. There are kits you can build and assembled ones pop up on eBay now and then. It’s not that likely the FBT is bad on your CC though. What’s the symptom You’re experiencing?

Requires 4GB of RAM. Imagine telling that to a Marathon player in 1994 :D

I wonder if there’s a way to reverse the state of brittle plastic. Perhaps heating it for some time just below its melting point would help? Anyone know the chemistry of ABS and other plastics used in these products well enough to know what if anything might help?
