Project: Silent Overkill

Wibbly Wobbly USB Oscilloscope is surely the official product description. And should be if it's not.

I've been around looking in from time to time, but never had the brain space to usefully comment :P still don't tbh, sat here in the new house for 12 hours waiting for a fridge that nobody wants to give me tracking data for, whilst nothing is getting done at the old house.

Putting the big res in the middle of the distro has done a great job of separating the two halves so all of my concerns and brain wrangling to try and suggest some kind of symmetry in the tube runs is n longer needed.

Does the D5 NEXT work upside down though?

New house is at least some progress though. Deliveries are always painful - more so when you cut them open and find that what you've been shipped is not what you ordered.

If I had a vinyl cutter I'd rename it now! :D

I've not got any D5 pumps, they're all DDCs. The lump on the top of the res in that model is a LeakShield....that I probably don't need, but want to play with :D You can see the DDCs lurking under the distro near the rear of the case....not for any specific reason, just to put them somewhere so I don't forget about them :D I may see if I can get one under the res - seems to make sense - and have one essentially either side of the feed and return to the external rad. Still gives me fault tolerance but makes sense (at least in my head!) to split them so they're acting at different parts of the loop. Probably one of those things that if you tested it, would make as near to zero difference as makes no odds *shrug*
 
I've still got the volute work on my desk. Got as far as nearly fitting the XSPC volutes I somehow feel I have to copy (I guess they're a know good and tests show they perform well) but then ran out of sanity. The shape is a bit incomprehensible - honestly, I wonder if they just sketched some slightly random curves spiralling outward and said "That'll do!" and just nailed it through chance!
 
Yeah, XSPC's volutes are completely different to mine and what Joe Robey suggested to me. Theirs looks like they take a "pool" in one corner and spin that fully around the volute to the outlet, whereas mine and Joe's (so I would resume EK's given his time there) progressively expand from the centre. And Alex Banks doesn't even bother with a spiral in his distros I don't think.

But if it works it works!
 
I'm sort of stuck between the desire to have a nice mathematically clean curve and the 'need' to make it the same as XSPC's. As you say, the difference is probably inconsequential - especially with two of them in the loop. I'll get over it once I get back to that part of the problem. Need to locate them in the distro plate first before that becomes the main problem again.
 
Quick update on the res. I heard nothing back from the adhesive manufacturer so I've approached Henkel (the company behind Loctite). I've had a preliminary reply and provided more detail so hopefully they might be able to suggest a suitable product. One of their questions was how many per day I'd be making...hopefully "one...ever" hasn't put them off too much! :eek:

I've heard back from Henkel. The delay was just an email getting lost; they've been very responsive and helpful - as they were last time I asked them something, to be fair.
There were two possible products: EA 3430 which is cheaper, more available and more convenient....but starts rapidly loosing strength about the sort of temps we may be reaching. Could well have been fine - 25% of 100 times stronger than it needs to be maybe...or it could have let go once up to temp. Not an engineer, not a clue so I went for the safer but more expensive option of V5004. It looks like I'll be safer to make the rings out of mild steel as both of these adhesives stick better to it than to aluminium.
I'm going to get the adhesive, the dispenser gun and the glass ordered today. The glass, but you were going to use the piece that's sitting on your desk weren't you? Well yes, that was the plan. The thing is, the mount for the LeakShield unit is for a 65mm OD tube and the one I have here is 55mm. I think it's going to be a lot less work to match it than to try and adapt it so I'll drop £20 on new glass rather than lose £40 worth of sanity. Seems like a fair trade to me!
Now that I have to* use steel, what's the betting that I have a chunk of aluminium in stock that's perfectly sized but no steel! :rolleyes: Hey, I'm not pessimistic, I work in IT....we call it "experience"! :D

* That's "have to" in the same way you "have to" have a 4080 Super rather than a 4080 or a 4070 :D
