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 [...]
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 [...]
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 [...]
“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.

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 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 [...]
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 [...]
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:
