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.

When you're playing it, it feels like the video game representation of some real-life sport. You're bouncing a ball back and forth with another player, which at first glance sounds a lot like like table tennis, AKA ping pong-- and that would seem to explain the name. And yet, PONG is two-dimensional and free of gravity. The ball goes in a straight line, at a fairly constant rate of travel. And you don't play ping pong by rotating a wheel. Come to think of it, it's not a darned thing like ping pong. So what the heck is it?
To answer this, we built this real-life Tabletop Pong game. You can read more about this project here.
The two avionics designs for Martlet 2. The final rocket will have two of the flight computer (one in the body and one in the nosecone) and one 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 flight computer features three K-type thermocouple inputs, three strain gauge half-bridge inputs, three 1A pyrotechnic outputs, a full IMU (±20g and ±200g 3axis accelerometers, 3axis gyro and magno, barometric pressure), a micro SD card for datalogging and a serial interface to the radio and other peripherals.

Though it's not finished (the wall), and it's nice that they kept the signage they already had at this time, they got around to moving Electronics to their new area. Exciting!!!! My friend, Joe took this picture for me because he happened to be in this Target at the time. This visit was 1/18/11.
Have an electrifying weekend.

My vote for "technological innovation of the 20th century" - the transistor.
You could manufacture a single microchip with way more transistors than these in it nowadays.

This is one of 7 pictures i took of shopko that i forgot i had. This is a picture of the electronics section at shopko
Seen Here: The PCB out of the bag!
So, today my PCB for the LED matrix arrived from BatchPCB! For what I paid, the PCB arrived fairly quickly - I ordered it on the 15/02 I believe, and it arrived 11/03 -- 26 days, which is pretty good (they state 19 business days).
The quality is very, very impressive - far better than anything I could pull off at home. The silkscreen and soldermask makes it look really nice, too.
Soldering it was a joy, although there was a LOT to solder and it's all surface mounted.
I had a few problems at first; it wasn't lighting the matrix at all properly but I soon realised with my new design (transistors on the cathodes) I have to write the transistors HIGH to get a LOW on the cathode, so a quick line of code changed to get that working.
Then for some reason the top half of every letter was flipped. It turns out this was my fault: I messed up when making the package for the LED matrix in Eagle, swapping the matrix's 5th cathode for my system's 8th, 6th for 7th, 7th for 6th and 8th for 5th. This was fairly easy to fix in code, however.
Finally USB isn't working to program or communicate, but I can configure the FT232RL chip (after all, it's sending the clock pulse that's driving my ATmega168). I think I have an idea of what's causing this, but I'm not sure yet.
Consumer Electronics Apple iPhone Distributor Samsung Mobile Phones
Undoubtedly, many electronic consumers are interested to use good mobile devices for their use. Most of the people are using brands such as iPhone devices and Samsung mobile phones for their use. Consumers consume electronics devices if they are getting what they need at a good price, with good features. Apple iPhones and Samsung mobile phones distributors have an easy process to sell their brand products because they feel that to invest in a product which is easy to sell by its brand’s name then this is the best thing to do.
GlobalGeeks has services for both electronic consumers,
whether they want to buy Apple iPhones or Samsung phones. This not only provides you with the best services for being their customer, but you will get optimize products quality with best facilities. These smartphones have been sold by many other companies, few have Samsung devices, few have Apple iPhone’s distributorship, maybe it has become little tough to decide which is good to buy by comparing them. If you visit a distributor who has both of the devices, then it might be easy to purchase the best suitable mobile phone for you by comparing all of the latest available devices.
Consumer Electronics Apple iPhone Distributor Samsung Mobile Phones
This is itself a big task to have the distributorship for two big brands of the world, Apple iPhone and Samsung mobile phones. It has more things rather than to invest a huge amount into it. This proofs that GlobalGeeks can manage or run two big brands distributorship so that it could reach out to the people easily. This is also a good ideology for the consumers of electronic gadgets, who love buying the latest phone available with the new latest feature. If you want to buy the best and latest electronic devices for you, then you are at right place. Just give us a call and get to know more details about your favourite devices.
This is a test circuit I cobbled up today to try out an Optrex DMF5005N graphic LCD display.
Here you can see how what is a nice neat ribbon cable / IDC arrangement on the display side becomes a horrible Cthulhu-beard of wires at the breadboard side. Each ribbon cable conductor is a stranded wire, i.e., a collection of hair-fine wires that would be hopeless to stick in a breadboard socket, so I tinned all of them with a drop of solder to stiffen them up. The result? The technique worked, but I can't really recommend it. In fact, I anti-recommend it. It's a lot of fiddly work to tin the wire ends, and it would be very easy to break them off in the breadboard. When I get past the driver prototyping and get around to using the display in a real project, I'll figure out a nicer way to interface it.
As you can see from the rat's nest on the breadboard, wiring a display like this takes a lot of signal paths - it used all but two of the I/O pins on the ATTiny861 MCU, so that chip is not a great choice for this LCD if you mean to do any chattering with any other peripherals. The data lines could be shared, but I don't like the kind of juggling you have to do for that if you can instead just use a chip with more I/O lines - and as it happens, I have several of them. I chose the Tiny861 for this test because it's a very easy chip to debug in-circuit using the Development Environment of Kings. That came in handy for this projecteen because my code did have a bug in it which the in-circuit debugger helped me track down. Yay!
My goal for today was to get this display to show a checkerboard pattern of 8x8 pixel squares. I pulled it off! Fancier stuff can come later - a large fraction of the effort for projects like this is to get the circuit to do anything at all, and once that's going, the rest is relatively easy.
