Re: best cheap/free scores 1.1
More scores today.
HP dv7-1120eo - awfully dirty, surprisingly started working after I left it heat up (it's freezing outside), does enter Windows but I suspect LVDS isn't working as I have nothing on screen. (keyboard is responsive tho.) Came with 2GB of RAM and some random 2012 datecoded 500GB WD Scorpio Blue that, despite being disgustingly dirty, is at 100% health.
Xbox 360 - my first one so appreciate anyone who can give some help on it. 2008 datecode, and has a criminally heavy 160W brick.
WYSE KU-8933 keyboard - nice membrane-based Model M clone w/ Windows keys, and surprisingly clean.Main rig:
Gigabyte B75M-D3H
Core i5-3470 3.60GHz
Gigabyte Geforce GTX650 1GB GDDR5
16GB DDR3-1600
Samsung SH-224AB DVD-RW
FSP Bluestorm II 500W (recapped)
120GB ADATA + 2x Seagate Barracuda ES.2 ST31000340NS 1TB
Delux MG760 case

Re: best cheap/free scores 1.1
Today's dumpster dive (since I couldn't edit previous post) - a Kyocera Mita FS-1018MFP multifunctional Scanner+Printer. Jams a bit but then starts off fine, guess I gotta roll it every now and then?
As for the above scores:
- dv7 works fine and silent after a reflow on both chipset and GPU - surprisingly this one is the only one that didn't give me the "CMOS checksum error" at every boot regardless of the CMOS battery being new or not.
-360 works, need to clean it up and unjam the DVD drive. May RGH or JTAG it, depending on availability.
-WYSE keyboard works and is absolutely splendid for a membrane based Model M clone.Main rig:

Re: best cheap/free scores 1.1
Sounds like rollers or roller clutch.
Anyway, on last month got MS-6501 dual socket A board with adaptec sata controller and bodged geforce 6200 on it for agp testing purposes, Dell 27" 2k monitor with random blackouts and fully working Aiwa AM-NX9 netMD player with bunch of disks.Attached FilesComment

Nice! Check the caps. Hard to tell from the pic, but there looks like a bloated Rubycon right next to that 4-pin addon plug for the 20 pin ATX connector.<--- Badcaps.net Founder

Re: best cheap/free scores 1.1
The only thing I would be worried about is that Stinkworld PSU. I wouldn't risk running a dual Athlon machine with that cheap PoS (and yes, I do admit Linkworlds are crap) at all, especially since they're horribly hungry on the 5v rail. Not that the 12v isn't also required to be high, but still.Main rig:

Re: best cheap/free scores 1.1
In the LA area we see a lot of big screen TVs sitting out on curbs for trash pickup. Most of course are junk. Just 3 days ago one caught my eye. Turned out to be a Vizio 55" 4k model from 2016. And I've never had a 4k TV! Thanks to this forum I was able to diagnose the common CPU BGA heat problem. Up and running in a few hours by baking the main board in an oven. 10 min @385f (I was too lazy and eager to wait a day to get a heat gun). Been working great for 3 days now!Comment

Re: best cheap/free scores 1.1
Another nice score IMO - two early phat Xbox 360s. One is a Xenon (no HDMI) and the other is a Zephyr (HDMI). Came with two rather corroded controllers - one cleaned up and works fine, the other may need some tracework done - as well as a headset, a 203W PSU and a nice Component+Composite official cable.
The irony - the Xenon is pretty banged up (blown KZJs near the DC input) yet no RRoD and runs NXE dash, while the Zephyr was in pristine condition yet it had RRoD, despite being repasted. Reflowed it quickly at 350*C with a paint removing heatgun. Was pleasantly suprised to find out the Zephyr unit had the original Blade dashboard!!! Also the DVD drive on this one worked. For some reason, the TSSTCorp on the Xenon won't do anything, no signs of life. Maybe a mismatched drive?Main rig:

Re: best cheap/free scores 1.1
Actually that was just temporarily one just to turn it on and test preliminary, already searching for 5V and 12V heavy enough psu. More dissapointment came when I discovered that cheap Radeon 9700 I got earlier has artefacts, and X1950 pro code 10 on one of two gpus in device manager...Comment

Re: best cheap/free scores 1.1
More updates on the 360s:
- Falcon unit received the power button from the Xenon unit
- Xenon unit is probably going to end up for parts - I can't for the life of me get the DVD drive to work, and I'm pretty confident it's the original drive that's in there - I haven't seen Xenons ship with anything else besides Toshiba-Samsung TS-H943 DVD drives - this one seems to be dead, won't do anything when pressing eject - checked all the mechanic side, everything looks fine. That, and KZJ caps galore
- Zephyr unit was reflowed, awaits some fresh MX6 to be applied because I'm fairly sure whatever was used on there is probably the world's worst thermal paste known to day, the kind that can barely cool a Celeron, let alone two 90nm chips.
- one of the controllers has a wrecked PCB, will keep it for parts or until I can find another one that's in rough shape and swap the casing on it. The other one works and currently uses some VARTA Alkaline LR6 batteries (I know, VARTA sucks balls, but tit's the only kind of batteries I could find cheap enough to buy a pack of 4 of.).
Next step is probably getting both units RGH'd. I would have loved to JTAG both of them but I couldn't find anyone to do it, and I don't have the tools necessary to do it currently. (unless I can JTAG a 360 through a LPT port... even if that means waiting a century to write a NAND

Re: best cheap/free scores 1.1
Probably stupid question but is there led activity when you press eject? Maybe just dead button? Because that's quite rare when optical is so dead it even don't recognize simple commands.- Xenon unit is probably going to end up for parts - I can't for the life of me get the DVD drive to work, and I'm pretty confident it's the original drive that's in there - I haven't seen Xenons ship with anything else besides Toshiba-Samsung TS-H943 DVD drives - this one seems to be dead, won't do anything when pressing eject - checked all the mechanic side, everything looks fine.

Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.
My computer doubles as a space heater.

Re: best cheap/free scores 1.1
Nope. The drive is dead, as far as I can tell. Won't do anything across all three units - Xenon (the mobo it comes from), Zephyr or Falcon. Swapping the semi-broken Lite-On from the Falcon into the Xenon does work - the drive does power up (haven't tried eject as the Falcon's DVD drive has broken eject mechanism). The TSSTCorp drive from the Xenon stays dead (no laser movement, NOTHING) across all three units.Main rig:

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...
