I'm assuming since pentalobe is common, you have the latter? :D

Criggie

No - I just find it so divisive that there's are further breakdowns on an already-esoteric design.

Journeyman Geek

the aster seems an aerospace thing

The wikipedia article on screw heads is surprisingly interesting

List of screw drives

At a minimum, a screw drive is a set of shaped cavities and protrusions on the screw head that allows torque to be applied to it. Usually, it also involves a mating tool, such as a screwdriver, that is used to turn it. Some of the less-common drives are classified as being "tamper-resistant". Most heads come in a range of sizes, typically distinguished by a number, such as "Phillips #00". == Overview == == Slotted drives == === Slot === Slot screw drives have a single horizontal indentation (the slot) in the fastener head and is driven by a "common blade" or flat-bladed screwdriver. ...

I've been meaning to try and grind an old flat-blade screwdriver into a hollow-grind. Just to see if its possible.

Journeyman Geek

also don't forget there's 2 different cross heads, used to be 3 but JIS went semi extinct :D

and by 2 apparently I meant 10

Criggie

JIS exists on bikes - the adjuster screw for derailleurs is often a JIS/flathead combo

Journeyman Geek

apparently JIS got rolled into phillips

I was looking for one for some furniture and I ended up just using a phillips

speaking of that....

next project for me is apparently putting a set of budget audiophile equipment feet on my TV stand so that my vaccum cleaner will stop trying to climb it ._.

Criggie

heh my next projects are
* clean, reassemble sawbench and tune it
* Build a dust collector box for my cheap plastic cyclone
* build an enclosure for a 12" speaker as a sub.
* Make a cross cut sled or a mitre fence

All of which are tablesaw related

And wheels/casters

Journeyman Geek

lol

I got the core of my network house, waiting on the kitchen to be done

Still trying to figure out the computer desk ._.

Criggie

Oh yeah - I have a server to set up and install too, the current server is 1RU and *way* too loud.
But that's not a tablesaw project

Are you moved-in yet ?

Journeyman Geek

not really

@Criggie My current setup is a rather motley array of mini PCs :D

Criggie

I was tempted to go that way - move all my work to VMs and run them across a cluster of mini lunchboxes with the iscsi SAN in the backend.
But right now I need to work on the mortgage.

Journeyman Geek

@Criggie that's essentially the plan

my storage server was kickstartered so waiting on that (and I think if I was doing it now ugreen has some interesting ones) and the VM nodes/disposaboxen are ~70-80 bucks a pop

i do want to try to move/consolidate/downsize my dedi and host some stuff at home

Criggie

1:55 AM

yah - its always memory that's the issue though... Current server is 512 GB ram, and the replacement is only 64 GB. All the little hosts I found were 8 GB, or maybe 16 GB Not enough for a useful VM server

Journeyman Geek

lemme check

Criggie

that said - my old Everything physcal box is a core2 duo with 4 GB

Journeyman Geek

right now I think my proxmox box is 4 or 8

the 'new' chepies I've gotten are 6, and not upgradable I suspect

BUT they are cheap, low power and tiny

Criggie

that has an advantage too - I bet they're quiet.

Journeyman Geek

hm. 16

not a very expensive system IIRC

aliexpress.com/item/1005006510890816.html

these are the 'additional' boxen I have on order - probably will end up replacing the absolutely geriatric utility linux box with one or using it to play with a proxmox cluster or other fun stuff

@Criggie that's one thing I don't need to worry about. My apartment is fully paid off :D

Criggie

2:01 AM

Nice ! I was looking at HP and Dell and Lenovo like this:
https://nzpcclearance.co.nz/product/lenovo-thinkcentre-p330-tiny-pc-i5-8500t/
But $500 NZ is $404 SG and it still needs a lot of ram

Journeyman Geek

16 is plenty IMO

most people, myself included overprovision a lot

Criggie

$689 once upgraded to 32 GB and even that's not enough. I'd need two of them as a minimum, and one more as hot spare

My VMs all add up to around 75 GB at the moment

Journeyman Geek

ram? 0_0

ah

if I needed that much, uhhh

Criggie

yeah - OS disk's reasonable at about 330 GB total.
Data disks are around 9 TB.

Journeyman Geek

I'd say the cheap/small/quiet options are limited

Criggie

2:04 AM

yeah - and a lot of "consumer" grade stuff tops out at 64 GB total

96 or 128 would do me fine

Journeyman Geek

I'm essentially running HA and unifi for now

I think the current dedi is 64gb and runs a few webapps

but pretty sure I can move most of what's in the dedi into one of those cheap chinisum boxen for now, and I have a SFF NAS coming in that's got a slightly potato processor

ironically my 'bottleneck' is my cheap SSDs :D

Criggie

checked - I've got 63.3 GB of ram allocated to running VMs at the moment.

I've also got a desire to replace my core switch - its a 32 port 10G juniper, and its very nice but again its LOUD.

Looking at a "hasvio" hasivo.aliexpress.com/store/4651177

Journeyman Geek

I got one of their managed gigabit switches

they're essentially realtek reference designs

Criggie

2:20 AM

Is it any good ? I can't go to 2.5 or 5 gbit cos all my nics are 10G

Journeyman Geek

Its mostly competent

though most of the chinese stuff is SFP+

Criggie

Yeha - that's why I need copper, cos the NICs are all copper and replacing them would be a lot

Journeyman Geek

so you need to account for modiles

how many ports you need?

and managed or unmanaged?

Criggie

Definitelyt managed - I use ~5 vlans at home.
I've got 32 x 10g ports now, but could drop to 8~10 for the noise gain.
For most things, gigabit is fine. But VMs and iscsi likes more

Journeyman Geek

If you need like 4 - the unifi flex XG is probably going to end up 'cheaper' unless you got copper modules cheap

Criggie

2:24 AM

Yeah they looked good - with the fifth port at gig speeds as an uplink

Journeyman Geek

that's likely my future core switch :D

Criggie

Replacing the server is top priority - that's the most noise :-\

The juniper switch has ~6 x 40mm fans but they're weird double-thick stacked modules

Journeyman Geek

though my router is 2 x 10G SFP, 2 x gig SFP + 5 2.5 gig so... its mainly for my NAS and desktop if I want it in the same room

128gb + quiet + cheap is tricky

I THINK modern desktop/full ATX can do it

Criggie

perhaps new, but the stuff I can afford all stops at 64 GB maximum.
New's not on the table sadly.

Journeyman Geek

2:45 AM

there's those aliexpress LGA 2011 boxen but they're neither quiet nor energy efficient

and I assume its a proper server with mad airflow so you can't 'just' swap the fans

Criggie

correct - I did that and it hit 160 degrees C on the 10G nic in about a minute.
Noctuas just don't have the airflow needed

Journeyman Geek

9:11 AM

@Criggie huh

Those intels?

I run one of those on my systems and while it runs hot, I don't think they get that toasty

Criggie

Intel 520 chipset, and its on the motherboard right at the back. There was enough airflow with the 4 stock case fans at 16k RPM, but running 8x noctuas was not enough airflow, and the box shut down with a critical overheat.

So, I put one of the noctuas directly on the heatsink for the NIC and it works fine now.

Journeyman Geek

I've been debating strapping on/bolting on a fan to my 540T2s

Criggie

supermicro.com/en/products/motherboard/X10DRW-NT

the two NICs are visible along the top edge

and teh controller is just left of them, so its shadowed by the DIMM slots

Journeyman Geek

oh, onboard
