Practical Lead to Gold Conversion; or an Intro to Opteron Resurrection.

It so happens that AMD resisted the informal NSA ban on the manufacture of LinuxBIOS-capable x86 CPUs slightly longer than Intel did. Or perhaps they were simply slower to succumb to Microsoft’s Fritz chip decree. Whichever may be the case, vintage (pre-2011, with some caveats, inquire within) AMD Opteron motherboards are a precious [...]

The Care and Feeding of the Sage SmartProbe.

If you cured your Sage SmartProbe of its congenital disease as per the last article on the subject, you may now be wondering what to do with it.
The vendor supplied a massive Java shitware with the thing, which does not merit any discussion whatsoever. Instead, we will use the probe’s very spiffy GDB-compatible interface. Configure [...]

A Complete Pill for the Sage SmartProbe.

The Sage SmartProbe was a very spiffy “Hard ICE” debugger, one of the few ever manufactured for use with modern (2010s) AMD x86-64 processors, and – as far as I’m aware – the only one ever sold on the mass market, rather than as part of “favourite son” deals (as, e.g., Intel’s, and Arium’s similar [...]

Terraforming the “MyCloud Mini” : TTY.

“MyCloud Mini” is a ~$50, dual-core ARM, 256M RAM, 256M Flash, dual SATA box, in various respects similar to the famous PogoPlug.

Use a standard (e.g., CP1202) TTL converter. And you will get:

I had the honour of being invited to Trilema 2014 in Timișoara - where I exhibited a few completed gadgets.

Mechanics of FLUXBABBITT.

The public discovery of FLUXBABBITT, a modestly-clever American spy gadget – that may or may not have been “fired in anger” yet – has provoked the usual flood of media garbage (“JTAG is a Chinese back door! Threat or menace?”) What follows is some basic investigation regarding the plausible workings of this device, based only [...]

Cardano Prototype Tidbits: TRNG Boards.

Cardano is a joint project of yours truly and Mircea Popescu. The objective: an inexpensive, user-auditable gadget which attempts to deal with the problem discussed in “Don’t Blame the Mice.” Refer to Mr. Popescu’s page for more details.
The device consists of a mainboard (not yet complete) to which two TRNG modules, containing two equivalent analog TRNG [...]

Wanted: FLUXBABBITT.

By now, I imagine everyone with the slightest inkling of an interest in electronics has seen this scandalous tidbit:

To anyone who has received this generous gift from his Government, I offer:
4 Bitcoin for either of the above, in working condition. 1 Bitcoin for a dead or untestable unit.
Serious inquiries only! Please attach two high-res photographs [...]

Household Tips: Reviving a Dead Laser Cutter.

Not long ago, I happened to come across a very cheap and heavily used CO2 Laser Cutting Machine, made by Full Spectrum Inc. About 1K USD, including curbside delivery from across the continent.  I also bought the traditional water chiller, air compressor, exhaust manifolds, etc:

The junk seller promised an intact tube, and indeed there was:
