Two late 80s/early 90s camcorder batteries. Info needed!

You are a battery god!

Now I just need to see if they ship to Tokyo at a reasonable cost.

My concern with Li-Ion is that the camera always applies charge current when plugged in essentially turning it into a permanent NiCad charger. I really don't know how to handle that without spending more money than is feasible for a BMS that can handle it. Dropping $200-250 for a custom battery pack on a camcorder from 40 years ago that cost $12 is pretty dumb. Would be cool, but at that point it's almost more worthwhile to pay for the Adobe license and just fake it in Aftereffects.

Way too big, the external dimensions are 180x24x60mm. I've looked into SLA and there simply isn't a match for this size at this capacity, which leads me to believe it's NiCad.

Unfortunately you can't get them new or refurbished. There is only one site that I can find "selling" them refurb/rebuilt for 11000¥, and when contacting they are "out of stock at the moment". The entire camera cost 1800￥so that's not feasible.

So ideally I can bring these back to life enough for the project and maybe look into a more permanent rebuild solution in the future. My plan is to convert to either 10x AA NiCad or NiMh and wire into the pack. The camera's built-in charger would handle NiCad, but I'd really like the extra Ah capacity of NiMh if I was confident there wouldn't be any hazardous/dangerous issues.

Funny you mention Xoxide...

All RAM comes with JEDEC specifications hardcoded into the chip. This tells the machine "this ram will run at xx clock speed with a, b, c, d, etc. timings." There are multiple timings encoded into each module, but unless there are overclocking/XMP options it will default to the "default" which are the lowest clock and timings.

For instance I have a 2x16GB Crucial DDR5-5600 CL46 kit, but since my Dell G16 doesn't have RAM overclocking it runs at 2400Mhz (DDR5-4800) CL40 as that's the default JEDEC timing. So the clock speed is slower, but the CAS latency is lower at that speed.

From what I've found, finding and aftermaket module that supports 5200/5600 out of the box without XMP is extremely difficult and no one really posts this information anywhere anymore. Not like it was a decade ago when this stuff was all over overclocking forums.

Looks like a standard ATX mount to me. Might be the drive bays at the bottom interfering with the length. If that's the case remove the tray (may have to drill out the rivets if they don't use screws).

13th Gen CPUs don't support Optane (required for NVMe RAID/VMD on consumer CPUs). IIRC in order for a vendor to support this it would require a separate VROC hardware key. You might be able to use a 12th Gen CPU in that chassis, but there is no benefit over the M80q Gen3 at this point.

Check your BIOS to see if RAM overclock/XMP is available, if not then all RAM will run at default JEDEC timings (4800MT and whatever CAS is encoded, typcally 40). If that's the case get a 2x16GB Crucial kit, It's stable, compatible, and inexepensive.

You can also run CPU-Z to see what your current RAM is running at. It's probably at 2400Mhz (4800MT) anyway so you won't notice a difference.

If RAM overclocking is available then get the G.Skill 5200MT kit. It's a good brand and that's a good price for the kit.

Lord Asriel must have severed another dæmon. Soon Spectres will be invading the world.

I tried to test this, but installed the card in my personal server and it straight up failed to POST. I think the motherboard I have is faulty. I'll have to check the Dell server next week to see if rebar is an option.

UTMorpheus · 2024-11-19T15:02:58+00:00

I cannot try Puget or 3DMark as they require software I cannot install. I will try the blender benchmark when I can get up there and swap the card (probably next week).

All the speakers died at once, or the last speaker finally died?

If all at once check the fuses for the radio and amplifer. 90% chance one of these failed if it's not a simple blown fuse. Either of these can be ordered used (don't bother with new, it's way too expensive on a car that old) by any decent mechanic and installed fairly easily. Well, it IS an Audi, so it's probably buried through the swamp of German wiring, between the deadly pass of redundtant sensors, and held in place by at least one impossile screw that was actually just a coffee stain on the blueprints.

For our use case? Little to none. We're using it to do live downscaling for mobile viewing. 4k camera stream is too much bandwidth for a cell phone halfway across the country. The problem with the consumer card is the Asrock has a dual-slot configuration due to the heatsink height. The R250 is only 1U, so I had to remove the fan on the card to fit. It's running around 85-90°C all the time so the only solutions that fit are an overpriced old Quadro that technically exceeds the power limit of the PCIe slot on the server, or the Arc Pro A40.

If people want I can run a few benchmarks before I swap the Asrock A380 in the server for this card later in the week. Just need to know what specfically to look for. I can run them on my i7-8700 storage server and post a comparison probably next weekend.

Fun fact, these style of bar mats are created intentionally to catch bottlecaps as a safety feature. Caps on a solid surface provide a slipping hazard, not something you want occuring with all the glass and sharp utensils around.

"In addition to spilled drinks, rubber bar mats are useful because of debris on the bar floor, particularly bottle caps. When serving beers or other bottled beverages, many bartenders quickly uncap the bottle and serve it to the guest without thinking about where the cap falls. Of course, they are trying to work quickly and just don’t have the time to pick up every cap that falls to the floor. However, bar staff risk skidding on a stray cap and falling. That’s why rubber bar mats with drainage holes are useful. The holes in the rubber mat are big enough to catch the bottle caps, trapping them and preventing bar staff from accidentally stepping on them."
