Gadgets. I built one working PC out of 2 dead ones and added a HDD from an old expired PVR. Recycle, re-use, recover. And yes, it got a bit dusty in there!

Exemplo de placa-mãe de Pentium com os famosos chips de cache falsificados, episódio muito comentado na época. Quase uma peça de colecionador!
"Vintage Computers" Series:
Example of a Pentium mainboard with the infamous fake cache chips. That episode was quite commented at that time. Almost a collector's item!

While my Macbook is being serviced (keyboard repacement, and LCD inverter / LCD screen replacement ... love applecare), I thought that I would build myself a cheap PC to run adobe lightroom (yeah for cross platform compatability).
For the princly price of $601.00, I built myself the following system:
Gigabyte G31-ES2L motherboard ($97.00)
Intel Core 2 Duo E7300 CPU ($200.00)
Kingston PC6400 DDR2 4GB Ram ($75.00)
Western Digital Caviar SE 80Gb SataII HDD ($72.00)
Antec NSK 1380 MicroATX case w/ 350w Power supply ($157.00)
I use an external DVD ROM drive because I'm too cheap to buy one to install the OS. I've still got to get a WIFI card for it, the spare ones I have don't work when the computer has more than 2GB RAM installed (don't ask...)
Took around 1 hr to build, and is running Windows7 ultimate beta. Never seen lightroom run so quick!
One day I came back from work early summer I sensed this funny smell. I tracked it back to our computer up in the attic, but could not clearly see what could cause the smell. So I just powered it up to test when a 10 centimetre long spurt of flame raised from the mainboard.
The computer has never been in use since.
I stripped down the pc today because we've got a new socket 775 mainboard ready for intel dual core, and discovered how bad it really looked.
Pogo pins come down on mainboard to test, connected to various peripherals via breakout boards and wires.
My brother's laptop pc, an IBM Thinkpad R31; it died a little while back.
Well it didn't exactly die, but the screen went so dim you could only just make out what was on the screen by shining a light at it, as good as blank and basically useless. Annoying, because it's a pretty good computer, and had a stack of files on it that, as a result, we couldn't access.
Interestingly I tried plugging in an external monitor and this wouldn't work either. I can only assume this is because an external monitor still gets its backlight power from the source computer.
So I googled around a bit and discovered these symptoms sounded very much like a 'Screen Inverter' failure - that skinny little pcb card I'm holding is this bit. Apparently its sole purpose in life is to take the DC power it gets from the pc mainboard and invert it to AC so it can power the backlit screen.
We bought a new (or more likely a rescued) part, and used some instructions I found on the web to fit it. This meant dismantling the screen frame which was a bit fiddly, removing the old pcb and plugging in the new one.
Job done, and as you can see, the screen is now up and running again, and this is me demonstrating where to fit the replacement part.
Main logic board of the machine. This is with the top cover removed, the front panel is to the right. Note that the power switch is a fairly high-rated circuit breaker, not just a switch. The power jack (top left) is heavily shielded and has a number of filters in it.
Visible at the bottom of the frame (with the red "warning" label on it) is the high-voltage stuff for the oscilloscope display.

As fitted to MacMiga's A600 project (see next pic), this is the Individual Computing ACA630 upgrade packing in a 25MHz 68030 with 32MB of SDRAM Fast RAM on an expansion that is screwed to the mainboard to avoid it popping off the onboard CPU.

Aqui puedes ver como he des soldado los contactos de la pila, para poder luego sacar el mainboard.
