Re: So what bargains have you picked up and fixed / easy fixes?
Hi all,
My specialty is I fix the 'weirds'.
If it is something different or strange, that is what I like the best.
Ages ago I used to fix moving message signs back in New York.
Fixed an annoying LED sign for a neighbors beauty shop near where I work.
It reads in LED's
SPA
Pedicure
Each letter comes on and as the word fills in starts to blink.
The problem was the A in Spa was out.
This was offensive to me on a few levels.
First off the lady who owns the spa would never be able to fix it.
I doubt the vendor would ever fix or replace it.
And I did not like to see it just read SP.
So I asked for the chance to work on it.
That almost was an error.
Cheap crap Chinese manufacturing. Saw a lot of that when I was in Kuwait.
They build stuff that is so bad it's hard to imagine people spend good money on it.
Fixed some clearly sub standard wire work in the sign and got it back to life.
Can't imagine how these units were ever UL tested.
That is my only recent 'fun' story.
Keep it sane.

>i did a full recap using NCC around the cpu and replaced *every* small cap with tantalum!!
14 of 15 of the bigger caps were bulging on the mb on mine so I replaced 'em all with the tallest caps (of the same capacity) that would fit - every one of 'em was a pain to get the holes cleared on, too, requiring soldering iron and stainless steel pick. I was very glad that it started right up after that ordeal. I'll try to attach a pic of the caps...Attached FilesComment

Paid a little more than I wanted to but really looking forward to working on this. It is incredibly wide, more so than it seems in pictures and curved too. Almost like the new curved TVs you see these days.
Just want to get it up and running first, give it a good clean and respay where needed. Then you know this thing is screaming out to be converted into a gaming rig of some sortComment

Re: best cheap/free scores 1.1
yea its pretty cool, I didn't even know what it was or what it was designed to do.
Spoke to seller and he said he used it for trading stocks, and they were sold back in the 90s to militaries, for CCTV etc
It seems to be using 3 GPUs to power the main 3 screens and the small OS screen is run by an onboard GPU either in the chipset or CPU (Although I don't think they made APUs back then)
Whislt ive not had a chance to look at it yet there only seems to be 1 power lead going in it, so somehow the PSU is also powering all the screens along with the PC side of things. Must be something custom as ive not seen that before.Last edited by mikay786; 07-28-2015, 12:44 PM.Comment

Looks to me a lot like something designed for video editing, based on the small unattached screen, card reader, etc.Comment

Re: best cheap/free scores 1.1
Scored a Beefy looking 60A RV battery charger for $5. It had a smashed front (broken ATC fuses) and no top cover, other than a bodge on the AC input side (extra resistors piggy backed) it's in good shape otherwise. All name brand components (UCC 'lytics, etc.), and almost looks to have been conformally coated. No model number though (must have been on the missing lid?).
I'll post pics in a bit... I wonder if it could be used as a car battery charger?sigpic

Re: best cheap/free scores 1.1
Here we go:
The end w/o fan was missing the screws too.
The 12V end is pretty beefy:
I've removed the two 30A fuses, as one was smashed. those are pretty beefy lugs, looks like 6 gauge wire might even fit
The other end reveals a bodge (factory?) and a cut wire (2nd red wire on the 12V feedback pair, that's what the twisted red/black wires are) Why there was a 2nd positive feedback wire is beyond me, maybe for a gauge? It also looks like there may have been soldered wires at a now empty footprint too.
Last, it has a good quality sunon fan:
I wonder if this can be (safely) used as a car battery charger? If not, it's a hella beefy 12V (well, 13.5V) source... ?Attached FilesLast edited by ratdude747; 07-28-2015, 04:08 PM.sigpic

It's just the first time I encountered having to treat *every* thru hole like that - but I've not attempted/repaired but a few, guess I really should get a heavier iron than the 30 watt Weller I've been using since 1981 &-)Comment

Re: Your Best Dumpster Finds
5 Epson Photo printers all just blocked heads and easily fixed, couple of other lasers needing new fusers but perhaps the weirdest in the back alley behind the financial district back in the days when dumpster diving was the in thing 100 copies of powerdvd xp , 100 copies of windows nt4 - im still selling them on ebay - only 20 copies of powerdvd left after 20 years lol
Best dumpster pickup was an IBM M1 Cube Server with all memory bays full weight 250lb - its in my flat as a coffee table and its easily the most impressive server in my collection!You are only too old when you say you are too old!!!Comment

Re: Your Best Dumpster Finds
Epsons? Throw them back out
They haven't made a decent printer since the late 90s! (although their newer enterprise/workstation level inkjets look interesting)

Re: Your Best Dumpster Finds
Epson does make some good printers, however they're the near TOTL and TOTL photo printers (think: $700+). Epson and Canon make the best photo printers for pro use.Comment

Recently I've gotten into EC flashing due to my broken laptop(s) and started frantically searching methods for flashing the IT5571E-128 chip on the cheap(due to me beaing a student and not having a job) and noticed that ITE newer chips can be flashed via ISP (In-System Programming) either via SMBus or the KBC (EPP - Enhanced Parallel Port) interface. While these can be achieved with programmers like SVOD4/3 or the RT809H/F those options are WAYYY out of my budget so I was horrified. But recently I stumbled uppon some programmers on aliexpress that claim they can program a variety of ITE chips...06-17-2025, 07:17 AM -
My Mom bought some cheap motion sensor lights on wish... then complains about about batteries and this thing chews though them, well it uses 4 AAA batteries and a pack of rechargeable ones is about 13 USD
well since it uses 4 AAA and rechargeable are 1.2v and non-recharge at 1.5 this thing must work with 4.8-6v, I'll shove a USB cable on it, infant i will use a broken phone charge cable... dam this thing uses 430 mA and they made it battery powered...
lets ignore the fact that i thought the board fit both ways... and the wire color is reversed going to the board... -
Hi all,
I was looking to upgrade my main multimeter (Asita MD591) with something that has more features. I'll use it mostly for board diagnostic and diy repairs. I've been eyeing out many of those multi-function ones from Aliexpress but can't seem to make my mind up. Here are the features that I'm looking after:
- Autorange
- DC volts up to 30V
- Accurate Resistance
- Diode test (Beep mode)
- Frequency up to 200MHz
- Capacitanze up to 5000uF
- as cheap as possible
Other functions are not needed but those which are needed... -
Just as the title states. Two cheap SiS machines, surprisingly stable.
What I will tackle in the near future (the build will be slightly postponed due to slight stomach issues - am still recovering and my physical power (sorry if it sounds weird,English isn't quite my primary language) isn't the best at the moment. Especially with the diet I have to take at the moment.) are two SiS based machines.
The first one is a IPC rebranded Mitac 7521T. Why did I feel the need to tackle this machine? Well, just look at the specs:
CPU - P3 1100MHz Coppermine... -
"Caseless Cheap Chinese electronic tools" I mean things you get from banggood, ali, fleabay, Am-Zon, etc. like AVR-Transistortester, miscellaneous signal generators, frequency counters, (variable) power supplies, oscilloscopes, low resistance meters, etc., etc. that comes optionally with a case, or comes only with a cheap piece of plastic that barely provides protection to the PCB.
Just wondering what of these (generally flimsy) tools you actually find use (almost) everyday and find indispensable for the price, compared to buying a Fluke or whatnot, if there is an expensive...
