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.

Submitted for Our Daily Challenge for Wednesday, June 1 - Eccentricity. The Chinese guys who run the restaurant next door certainly thought I was eccentric for crawling around in the pile of trash for twenty minutes to try to capture this old tv set from as many angles as possible!

A photo of the Cockpit of ZH856. A Royal Navy HM.1 Merlin helicopter from 814 Squadron. 814 Sqn based at RNAS Culdrose also known as 'The Flying Tigers'
Numerous buttons, switches, knobs & levers everywhere taking into account there are even more controls on the touch-screens that cant be seen whilst the helicopter is shut down. Hard to believe each one does something different!!
Timelapse of building this workspace from scratch: youtu.be/ylsPUIXqirk
I spent the last 2.5 months finishing this space in what used to be an unfinished corner of my basement.
I2C debug port is working!!!!!!!!!!!!!!!!! As you can see this was done ages ago, it's only at the end of last year I resumed work on this.
Getting I2C access and framebuffer access took two weeks of work during holidays (including many unsuccessful attempts at JTAG)...
The Xtensa boot only took a week to get it to write to the framebuffer from the Xtensa code... It took much longer to get the newlib C library and RTOS (FreeRTOS) running on the Xtensa itself, register windows making CPU state save/restore a pain...

Yay! My laser cut plastic from Ponoko arrived and like the best ikea flatpack it assembled together and all the parts actually fit!
It's six rectangles with slots in the top and bottom and ridges on the side, front and back walls. It doesn't hold itself together very well if you aren't careful, though a bit of glue would soon fix that. For now I'm leaving it as it is.
The main control PCB goes on the outside back, where you can easily access the buttons to change the time. Power supply is inside on one side wall, and the two nixie driver boards themselves are on the bottom. Amazingly, my laser cut holes line up with the holes in the PCBs and I am able to screw everything into place! Hurrah!
This work of art is inspired by the form of electronic circuits. It comprises, in its central part, a square covered by numbers 1 and 0, that is to say, the two states of signals in digital electronics. It also includes, on the left and right of the square, some words that summarize the main consequences, positive or negative, of digital electronics. These words, and the central square, are arranged on a support covered by the word "electron".Technique: paper, cardboard. Size: 82 x 29 cm.
An Arduino microcontroller uses a CdS photocell and a set of LEDs to indicate the ambient light level. (Move your mouse over the picture to see explanatory notes.)
Just fooling around because I was bored. Maybe I'll think of a good use for this later.

Designing and building a high power amplifier capable of driving low impedance (as low as 2 Ohm’s @ 50 Vpp) loads.

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.
