The PCB for M2R, Martlet 2's radio.
The radio board features a uBlox MAX-M8Q GPS with an LNA+SAW on the input, a Radiometrix MTX2 which can either connect directly to the output or go via a 500mW RF power amplifier, and an isolated connection to a RockBLOCK Iridium satellite modem. It's all powered by an STM32F303CBT7 microcontroller.

The PCBs were sponsored by Cambridge Circuit company, thank you! The Radiometrix MTX2s were sponsored by Radiometrix, also a big thank you!
Bigger than Bangkok's Ban Mo, bigger than Japan's Akihabara, or Taiwan's Guanghua Shangchang or Korea's Jong-no 3ga!
Homebrew Function Generator, .5 Hz to 100 KHz. Uses uA709 OpAmps. Built around 1972, or so, and still used occasionally.

Hacker (hobbyist)
In home computing, a hacker is someone who modifies software or hardware of their own private computer system. It includes building, rebuilding, modifying, and creating software (software cracking, demoscene), electronic hardware (hardware hacking, overclocking, modding), either to make it better, faster, to give it added features or to make it do something it was not originally intended to do. Hacking in this sense originated around hobbyist circles discussing the MITS Altair at the homebrew computer club.
Hacker artists[edit]
See also: Fractal art, algorithmic art and interactive art
Hacker artists create art by hacking on technology as an artistic medium. This has extended the definition of the term and what it means to be a hacker. Such artists may work with graphics, computer hardware, sculpture, music and other audio, animation, video, software, simulations, mathematics, reactive sensory systems, text, poetry, literature, or any combination thereof.
Dartmouth College musician Larry Polansky states: "Technology and art are inextricably related. Many musicians, video artists, graphic artists, and even poets who work with technology—whether designing it or using it—consider themselves to be part of the 'hacker community.' Computer artists, like non-art hackers, often find themselves on society’s fringes, developing strange, innovative uses of existing technology. There is an empathetic relationship between those, for example, who design experimental music software and hackers who write communications freeware." [3]
Another description is offered by Jenny Marketou: "Hacker artists operate as culture hackers who manipulate existing techno-semiotic structures towards a different end, to get inside cultural systems on the net and make them do things they were never intended to do." [4]
A successful software and hardware hacker artist is Mark Lottor (mkl), who has created the 3-D light art projects entitled the Cubatron, and the Big Round Cubatron. This art is made using custom computer technology, with specially designed circuit boards and programming for microprocessor chips to manipulate the LED lights.
Don Hopkins is a software hacker artist well known for his artistic cellular automata. This art, created by a cellular automata computer program, generates objects which randomly bump into each other and in turn create more objects and designs, similar to a lava lamp, except that the parts change color and form through interaction. Says Hopkins, "Cellular automata are simple rules that are applied to a grid of cells, or the pixel values of an image. The same rule is applied to every cell, to determine its next state, based on the previous state of that cell and its neighboring cells. There are many interesting cellular automata rules, and they all look very different, with amazing animated dynamic effects. 'Life' is a widely known cellular automata rule, but many other lesser known rules are much more interesting."
Some hacker artists create art by writing computer code, and others, by developing hardware. Some create with existing software tools such as Adobe Photoshop or GIMP.
The creative process of hacker artists can be more abstract than artists using non-technological media. For example, mathematicians have produced visually stunning graphic presentations of fractals, which hackers have further enhanced, often producing detailed and intricate graphics and animations from simple mathematical formulas.

WEEK 9 – Horn Lake OfficeMax Closing, Set 4
Looks like someone didn't care for this package! I photographed several other items throughout the store that were, shall we say, dilapidated, but this picture was the best of the bunch in capturing the yellowness.
(c) 2015 Retail Retell
These places are public so these photos are too, but just as I tell where they came from, I'd appreciate if you'd say who :)
The grocery part of the store isn't the only area the second story doesn't cover; the high ceilings wrap around to a strip along the front end of the left side of the store as well. That allows the electronics department to have such a fancy bit of signage (though the high ceilings are lost on the electronics department), and makes the left (main, at least in terms of exterior appearance) entrance span the entire height of the building.
It's rather interesting how electronics has the most monumental decor in the entire store here. I guess that's probably another 2002 thing...

Model 704 panel meter. Picked this up with a couple of others in a surplus electronics store in Toronto. I probably paid too much but I have a soft spot for anything Stark.
