The ghetto mod thread

Re: The ghetto mod thread

The chinese plated through, FR4 double sided copper ringed perfboard is indeed the deluxe bee's knees ... though I would really rather have a real PCB done, cutting veroboard or adding wire links is a major PITA.

Speaking of that, does anyone on eBay sell double-sided protoboard without PTH? I wanted some a while ago where I would have had to drill out the plating from about 80 holes...

Re: The ghetto mod thread

Yeah the radio shack copper ringed perfboard is pretty crappy (FR2 and not plated through). Veroboard is more sturdy but requires careful planning else a lot of cuts are needed.

This I did just to play with capacitive droppers... crappy soldering. That cold joint soldered LED is going to disconnect and the electrolytic capacitor will blow up

Oh... and do notice I reused this board. I think I used this board for something else, then ripped all the components out and built this on it. I wonder when it comes time for me to disassemble this and build something else

Re: The ghetto mod thread

it's not really ghetto, it's how everything used to be done, that and with stripboard.

the chinese even sell a deluxe variant of that board, double-sided through-hole plated fiberglass!!

Not enough light in picture

i've done worse i think

looks like a capacitive dropper power supply

Here is a brighter image of the underside. (i thought the top side photo looked ok despite it being darker)

I probably should have been a bit more specific with that last line (maybe some along the lines of 'what is the circuit powering' or something like that, oh well).

Re: The ghetto mod thread

Haha!
Looks like that fan's been running for a long time in there now.

Hahahaha, 6 years running, a good old Sunon MagLev fan oh and the mod is not just the cooler or the dust only, 4 aluminium heatsinks added made from a southbridge HS fixed with hot glue like it should be for a proper mod )

Re: The ghetto mod thread

Here is a test board i made of a copper-dot PCB.......

It may not look too bad but the bottom is where the 'fun' is.

As you can see, the soldering looks like it was done by someone who did not know what they were doing.

Note; I'm usually better than this (at least i hope i am) but this was a case where i wanted to get it done ASAP even if it meant cutting a few corners on soldering (which i usually don't do). This will not be going into use.

BTW: can anyone guess what this board is doing.

Not until that dust catches fire, anyway!

No more overheating for this TP-LINK Archer ADSL/Wi-Fi Dual Band modem router

With 2GB of RAM I felt like Vista/7 is too much for the machine so the best choice was XP (besides Linux)

Actually I don't think that PSU is made by apevia, is not that good but not near as bad as most apevia I have seen
This is the PSU, actually you posted a couple times on that thread

Ah you're right. I confused your thread with another one:
https://www.badcaps.net/forum/showthread.php?t=73043

From what I saw is a topower or at least based on the design

He said something about leadman but I don't think they can make something decent lol

Yeah, he said that only the last batch of Topower PSUs (before Topower seized to exist) were made by Leadman and not Topower. Meanwhile, it's Zumax that was made by Topower. So looking at how close that Zumax PSU is to yours, you probably indeed have a Topower unit.

Re: The ghetto mod thread

This actually looks pretty good. Hope you don't mind if I copy your idea. I need to mount a fan on a PC case the same way (it's a very old case with no exhaust or intake fans anywhere other than the PSU fan).


Now that is 100% proper ghetto!

Cool PC, by the way. If I am not mistaken that PSU is a YoungYear / Apevia / Aspire unit. Those green sleeved cables should be UV-reactive - i.e. if you add ultra-violet lighting in the case, it will make those cables and their connectors glow too.
Good overclock on that C2D CPU too!


Usually yes. But if you apply it carefully without pulling any strings from it, you can actually make it look pretty well. I do it around the cables of the probes of my cheap HF multimeters to prevent the cables from twisting and breaking. It looks almost like I have transparent sleeves on them. Eventually the glue does crack as I use them. But then all I have to do is re-heat the glue again and everything looks normal again.

Thanks, yes it's a nice way to mount a fan on a drive bay.

Re: The ghetto mod thread

Recently after trying hot melt glue (they're thermoplastic, not paraffin) I have a decision to use between hot melt vs epoxy... I like being able to reuse/repair hot melt where epoxy is pretty much set in stone after it sets.

Basically if it has to deal with any sort of heat, epoxy is used. If not, then hot melt glue.

On the other hand, is epoxy or hot melt glue cheaper per volume if I need to use it as potting material?

Re: The ghetto mod thread

no, i hate re-melt wax.

for me, a pack of epoxy and a tube of UHU/Bostik clear adhesive is the almost universal fix.

in reality you cant actually see the foam unless you get very close

Re: The ghetto mod thread

well lets start...
this is my main pc:
Asrock g41-vs3 rev2.0
Pentium E5700 @3.69Ghz (246 FSB IIRC)
4gb of ddr3 ram (2x2) dual chanell @984Mhz CL-7
PowerColor R9 270 Turboduo
Agiler Agi-1000ps psu
random case

on this pic you can see there is a black thing on top of the bottom fan(i saw that there was a hole on the bottom of the case, i had a 80mm low rpm fan that could take some cold air from the side grill for the gfx so...) is a 10w 20ohm resistor for the nidec beta V 92mm fan on the back

here you can see some tape on the 5v and ground wires, the cables connected to those are going to a guetto mounted 120x38mm fan that moves a ton of air even at 5v
