Ghetto Mods

It’s not really a mod.. but it’s a little ghetto in the looks department. I stripped the crossbar on my first FC140, so I took the one off of my TRUE Black :D

I seem to remember getting better temps with my first FC140.. so now I will try :cool:

Yup the fins are sharp under pressure.. was giving it a wash in the sink with some soapy water :D
Hmmmm My Mitutoyo stuff is usually Made In Japan.

This thread makes me feel way better about some of the stuff I do lol
 
I flipped the ducted heating fan around, now its ducted roof sucking
Works amazing, pulls the trapped hot air out of rooms even with the door closed and the roofspace is as good 15c cooler


Next up, i read the NBNco documentation on removing RF interference from VDSL lines, and discovered that they actually recommend making your own common mode choke with cat5e and a ferrite toroid

I then found an image of one used commercially in a youtube video of someone reparing an FTTB setup (fiber to many VDSL lines, in one room)

This was originally one socket that had joined wiring behind the panel, extending the phone line into the house

Now, it's 2 pin RJ11/VDSL on the left (over cat5e) with cat6 on the right, to a far away wall socket
Running the modem here directly had no speed gains, but the modem farther away with this inserted did

Is it massively improved?

Nah. But it is better.

So this basically acts as a bridge between two cables.

Does it matter where in the wiring you install it? (right after the modem, in the middle, etc.) might try with my ADSL though the speed is astronomically lower and it's running on phone wiring.
If it's worth something the wiring doesn't share conduits with anything else.
 
Well.. I would say the cooler works mint :cool:

No fans on the cooler:

More in the kbps range. DL speed is about 35-40KB/s from a direct server, torrents may be much slower depending on the seeds.
ookla test crashes trying to load because of how much crap they've put at some point when it was redesigned, prolly a lot of java bs lol I remember it being much simpler.

Hence the wiring, normal ethernet is only 10 mbps but I'm nowhere near that limit.

Yes, it's no different than using a short RJ12 or RJ45 cable - but was originally wired in series. I changed it this way to use a modem there originally, but room usage changed so the modem moved to the far socket

This is VDSL2 - it's got tighter requirements

The simplest version is: The less wire the better, even if its unused. Any Y or T branches with the wiring will absolutely hamper speeds, as well as any untwisted wiring (ADSL Is more tolerant there, as long as the pairs arent seperated - if they un-twist and go apart like in the old 600 series connectors, that can hamper speeds)

And hell just the inside of the wall sockets can be garbage

This is my brothers antique he's too scared to touch, the coward (VDSL has no dangerous live voltage - it's safe to touch. ADSL can have 50V, so be more careful about shorts
1674895752922.png

On VDSL, the blue and white wire should go into the socket no more than the length of that white arrow - and straight into the cable from there. The dance his wiring does running around is to an extra socket that never even got installed, and causes a LOT of CRC and FEC errors on his line


This is what mine looked like after a 'professional' had done the job to the minimum standards in a rush

1674896007359.png

The gel caps were loose, uneven lengths, and both caps had untwisted ends
Using the unused wires to hold it together is perfectly acceptable, but doing this is not

5Mb higher sync and speed doesnt change by time of day now
This is the opposite side of the wall the choke is installed, so it's preventing outside interference entering the internal wiring from this point
1674896082789.png



The internal socket got damaged a few years back by my dad being an idiot - ironically this person had at least tried to install it correctly, but had lost or forgotten the clear plastic cap to ACTUALLY HOLD THE WIRES IN THE DAMN CONNECTOR
You'll notice the lenghts are different yet again - fixing this obviously went from 0 internet to working,but getting those blue and white wires the same length took the speed up 5-10Mb at the time
Even 2mm of untwisted wire at the end there can slow VDSL speeds, ADSL is more tolerant but you definitely want solid connections of even length, with as little untwisted wire as possible
1674896158978.png


VDSL uses frequencies that some FM radio devices can send signals out, same as faulty AC appliances (~17Mhz)
Any Y or T forks of unused wire act as an FM radio transmitter and receiver, so your VDSL signal leaks out the wiring to the outside, gets picked up by the excess as static out of sync with the main signal, and you lose chunks of the available frequencies - so disconnecting extra sockets entirely is the only viable solution there (and as i did, using RJ45 jacks lets you simply extend to whatever socket you wish on the fly)


When i first moved in we barely got 50Mb, now we're getting 82Mb as i've learned a few tricks and bought the right tools. A new wallplate with a Cat6 jack and punchdown tool is only $20Au here, so it's an incredibly affordable thing to fix up (If its legal where you are, and safe - again, some older phone systems ran upto 50v when someone calls your number so it's best to play it safe if you dont know)

Mine too.. not sure what’s going on there..
Apparently they are made in Brazil Mitutoyo's own website shows it says made in Brazil on the dial all of their digital one however are made in Japan though
 
@Veseleil
Did you tape up the sidepanel? To prevent it breaking or getting scratched?
Nope, it's a panel made from plywood. Its main purpose is to serve as a test foundation, so I can add cardboard pieces, tape, etc. The final build will be either in the Your PC ATM thread, or in a dedicated thread. It kinda deserves its own thread, but I'm lazy to make a complete story out of it. Also my phone cam is damaged, so it can't capture the details the way it should.

In so many systems i've seen, those gaps are where all the dust comes in, or air pressure leaks out away from radiators

The airflow does sound smoother for sure, and I don't hear the Fractal motors growl nearly as much. Big difference. From 8 feet away it looks great lol, its nice to not see light leakage :)

Overall, I am a little surprised this is working as well as it is. Just the airflow alone sounds so smooth now.. the system is crunching right now so I do have some pressure on it.
 
I ended up doing the PSU compartment as well.. It’s ok! It gets plenty of fresh air from the main chamber :)

Hi,
Yeah I bought stock in black duck tape a while back :laugh:
 
Added some heatsinks to my wifi router
