History of DIY audio
Audio DIY came to prominence in the 50s to 60s, as audio reproduction was relatively new and the technology "complex," audio reproduction equipment, and in particular high performance equipment, was not offered at the retail level. Kits and designs were available for consumers to build their own equipment. Famous vacuum tube kits from Dynaco, Heathkit, and McIntosh, as well as solid state (transistor) kits from Hafler allowed for consumers to build their own hi fidelity systems. Books and magazines were published which explained new concepts regarding the design and operation of vacuum tube and (later) transistor circuits.
While audio equipment has become easily accessible in the current day and age, there still exists an interest in building one's own equipment, including amplifiers, speakers, preamplifiers, and even CD players and turntables. Today, a network of companies, parts vendors, and on-line communities exist to foster this interest. DIY is especially active in loudspeaker and in tube amplification. Both are relatively simple to design and fabricate without access to sophisticated industrial equipment. Both enable the builder to pick and choose between various available parts, on matters of price as well as quality, allow for extensive experimentation, and offer the chance to use exotic or highly labor-intensive solutions, which would be expensive for a manufacturer to implement, but only require personal labor by the DIYer, which is a source of satisfaction to them.

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.

Bud Industries, Inc., a leading manufacturer of plastic boxes, and other electronics enclosures, has introduced a DIN-rail-mount terminal-block enclosure that gives manufacturers more design flexibility, minimizes component installation time, and costs up to 25 to 40 percent less than comparable enclosures. It is ideal for housing printed circuit boards and terminal blocks used in DIN-rail mounted industrial controls, relays, and test equipment.

After a bit of a hiatus, I'm back fiddling with the Doughnut Board clock and I discovered that I had very nearly finished the mainboard! Even more very nearly than I'd thought. All I needed to add was one wire and a clock crystal, then install the chips.
...oh yeah, and one resistor I forgot to put in. Very luckily there was a place for it, since it's a fairly important part.
And with that, there was nothing for it but the inevitable bolting to a crudely-sawn piece of wood scrap and carting it upstairs to the software development zone.
So now, though it may not look like it, this circuit is a functioning clock. I was able to send a preliminary version of the clock software to the microcontroller (MCU) and monitor it through the debugging cable from the Development Environment of Kings. That allows me to start the program running on the circuit and watch its progress on my laptop's screen - what an age we live in, that this can be done with cheap hardware!
Currently the circuit just sets the time to twelve seconds to midnight, then I can watch the display tick over to 00:00:00 in the laptop's chip memory viewing window. Not quite as cool as seeing it on the actual nixies, but in its own way pretty awesome and a big rush knowing that I put at least that much of the circuit together properly.

A 0th-level attack at designing a direct conversion AM radio receiver. "Direct conversion" means we use a mixer (which just multiplies two signals) to downshift the radio frequency signal to baseband (audio) frequencies. I still don't really know how to couple the antenna into the circuit, how to use a crystal oscillator or a mixer chip, or lots of other things.
