Re: best cheap/free scores 1.1
Hit up the flea market yesterday. Came home with:
$10 - 2006 17" 2.16 GHz Core Duo Macbook Pro. Works great, sans battery. That's expected.
$15 - 2007 15" 2.2 GHz Core 2 Duo Macbook Pro. Motherboard seems to be dead, possibly the 8600 GT on it. Not worth the effort of fixing.
$10 - Fluke 73 III. Super greasy, cleaned up nice.
$10 - Axis Q1602 camera with Tamron M13VG288 lens and a Ram mount. Works great.
$5 - Lambda SR35-5 5V 7A PSU. Need to dig into this one, initial test I get a whole nothing from it. Verified power gets past the DC rectifier and didn't bother going any further.
$5 - Box of 5 23 GB Sony Professional Discs. Used, but interesting.Comment

Re: best cheap/free scores 1.1
fix the mac - people pay stupid money for mac's
and after watching some rossman, i'd clean the boards with ipa and spray them with a coating - they almost seem like they are designed to slowly self-destruct.Comment

Re: best cheap/free scores 1.1
I'd been away for too long (trapped in the house much of the past month) and they were gone when I managed to stop in, today. Apparently, they've found someone who will buy them by the pallet (which makes it convenient to get rid of them before large qualities accumulate). This happens from time to time -- until the buyer realizes just how many of them he'll end up "getting" (which is usually more than he can sell off!) and suddenly wants out of the deal!If they're still there, I'll pull their batteries as that's needless weight to ship.
But, I managed to pull a bunch of SCA drives out of a server (ISTR you were interested in those?). I'll toss a SCSI HBA in a PC (my only SCSI machine is a Sun that I haven't fired up in a while and I'd have to run headless) and wipe them (a condition of me taking any drives out of the facility) and see if they have any useful life, left.
Does "37228" seem like the proper destination? PM if you need more privacy...Comment

Re: best cheap/free scores 1.1
So, your adapters transition from the SCA to 68 pin ribbon (D connectors)? I.e., are 68pin drives also worth watching for?Comment

Re: best cheap/free scores 1.1
yesComment

Re: best cheap/free scores 1.1
yes, - usually.
i have some i used in sgi's - they are a pcb with an 80pin header on one side,
a 68 and sometimes 50pin header and power socket on the other side.
other than that you have some pins for device-id and a fuse.Comment

Re: best cheap/free scores 1.1
OK, I have a few like that (as well as narrow 50 to wide 68).
But, most of my adapters are "active" -- IDE-SCSI, FC/AL-SATA. etc. (I'm sorely tempted to, someday, stack a series of these end-to-end in Rube Goldberg fashion just to "prove" they all work, as expected).Comment

Re: best cheap/free scores 1.1
It's been a good month for HDD acquisitions.... Got 10x Hitachi 450gb 15k RPM SAS drives. I don't think I've ever had a Hitachi HDD.....<--- Badcaps.net Founder

Re: best cheap/free scores 1.1
A blue Dell Latitude E4300 with a good (85% capacity) battery and charger for $21:
And A Kenwood KR-4400 27 Wpc Stereo Receiver (circa 1974) for $20. I didn't really "need" it, but my dad had one when I was a kid (which was unfortunately lost in a move many years ago) so I always wanted to get my hands on another one and couldn't pass it up for that price. It needed a set of dial lamps (which Kenwood annoyingly soldered in instead of using sockets but I replaced them with LEDs so it shouldn't need to be done again for a long time) and has a couple chips on the wood veneer ends but otherwise is in great condition for a 45 year old receiver.

Re: best cheap/free scores 1.1
Scored a big haul of free stuff from an repair shop:
DFI Infinity NFII-M2 - nForce 4 SLI, Skt AM2
ASUS M2NPV-VM - nF6150+430, AM2
Jetway N2PAP-LITE - nForce 2, Skt 462 - I'm willing to bet this doesn't POST, looks like NOBODY replaced the GSCs and I suspect them being bad without any visible bulge.
ASUS P4C800 Rev2.00A - i875P, Skt 478
ASUS M2N 1394 - nForce 430 MCP, Skt AM2
MSI G41M-P26 - Intel G41, LGA775
ASUS K8N - nForce 3 250, Skt 754
ASUS A7N8X-X - nForce 2, Skt. 462 - blown KZG yet it surprisingly did POST!!
MSI K9N4 Ultra - nForce 550 Ultra, AM2 - dead chipset probably since it powers up as soon as I flip the switch on my PSU.
PS3 fat, CECHG04 - dead (YLOD), came with 250GB Seagate HDD
PS3 fat, CECHH04 - dead (same cause), had an golden Playboy bunny on top
And that's pretty much all. I know the owner and he said he's got a lot more but he needs to sort out all of his stuff in there.
He also has a nice KME/K-Mex case I might ask him about since that case also has a handle and I quite like the design.
(no PSU or anything in it, which means I can store a nice recapped KME unit or even a 250W FSP if I wanted.)Attached FilesLast edited by Dan81; 01-31-2019, 12:26 PM.Main rig:

I usually got used laptops with a bad battery, IIRC.
SCA's are used in scsi retro builds with adapters...and the adapters are something I have tons of!

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...
