DIY Chip Quik style desoldering alloy (#P37)

And finally closure on the fake China solder wire topic back from WHL #68 / WHL #68F1. I bought a bunch of Bismuth metal in early June (1KG Bismuth Metal Ingot 99.99% Pure Crystal Fr Making Crystals/Fishing Lures – 20.03€ including shipping, before the “no more VAT free imports” EU legislation went into effect) and with the high lead content solder from the other review, I should be able to make some low-melting point solder.

First of all, the Bismuth was delivered in a big chunk as advertised, which I did not expect. They are somehow able to split that crystallized cake precisely into pieces of slightly below 1kg and then add in small bits to make exactly 1000g (at 2 cents a gram, they clearly do not give away free stuff).

Fujitsu Esprimo E920 D3222-A12 12V/11Vsb to ATX conversion (#P28)

Recent hardware acquisition: Parts of an Esprimo E920 system (board, CPU, RAM and power supply) for replacing my main desktop system, a good old FX-6300 with 970 chipset board.

Why would I post about this? Well, it’s not a drop-in replacement. DIY required, since those OEM things always have some custom oddities. In this case it’s two (and a half) of them:

  1. Power supply has no ATX mounting bracket
  2. Power supply and board are not -12V/3V3/5V/5Vsb/12V units but 11Vsb/12V only
  3. Board has no I/O shield, just fitting case cutouts

Note that there are datasheets of this very Fujitsu board out there that show a regular ATX connector with all the standard voltages required. […]
