Modern Day Equivalent of Byte/Compute! Magazine?
MochaMan writes "I grew up in the '80s on a steady diet of Byte and Compute! magazines, banging in page after page of code line by line, and figuring out how sound, graphics, and input devices worked along the way. Since then, the personal computer market has obviously moved away from hobbyists intent on coding and understanding their machines down to the hardware, but I imagine there must still be a market for similar do-it-yourself articles. Perhaps the collective minds of Slashdot can divine some online sources of fun and educational mini-projects like 'write your own assembler' or 'roll your own bootloader.'"
A fantastic hobbyist type magazine. Our community college has a student subscription for it, definitely worth it. Edited by Steve Circia, name should ring a bell!!
From O'Reilly is about the only one which I can think of.
The Internet is this magazine.
Try looking at http://www.nutsvolts.com/. It has electronic and some programming at very low level.
Maximum PC is a great magazine.

I learned on Byte and Compute! as well but that's because back then that's all there was. That and a few books.
Now there's a gajillion ways now to be a techie. Whether it's coding to the metal or using JavaScript or Flash, using Java or C# or C++ or C or hand coding assembly. The number of ways to get the same buzz I got from those magazines in the early 80s has increased exponentially.
If you're stuck in the 80s though and just want to hand poke hardware then try the Arduino movement or one of these

And no, I'm not dissing those projects. I'm just trying to say that writing something in JavaScript or Python gives me the same feeling I got back in the 80s from typing in programs out of Compute! It's 2010. I'd much rather be programming in C# on XNA on my PC/360 than in basic or assembly on my Atari800.
Personally I prefer working with ATmega's directly rather than with Arduino, but ... if you want to futz around and LEARN, Arduino is a good place for it. Lots of tutorials and others willing to help. Lots of neat plugin boards for sensors IO. Lots of choices of example software from FreeRTOS to VGA output on a pin (both of those aren't designed for the arduino framework, but porting them should be rather trivial once you get to the point where you would consider porting them.
If you're using Windows, I'd suggest just using the AVRstudio from Atmel and WinAVR (GCC for AVR chips if you want to use C/C++ instead of just ASM). You can start with the Arduino development environment and move up later. Its free. The Arduino environment is really just a replacement for your main() with a while(1) loop on the standard AVR toolchain anyway
Arduino has lots of examples and information, but from a debugging standpoint, its the worst there is.
AVR Studio from Atmel has a nearly perfect simulator, and if you use something like HAPSIM you can simulate other hardware as well, such as serial ports, buttons, leds and a specific LCD.
If someone would add some decent debugging abilities to Arduino it'd be a useful development environment for me, but debugging through the simulator might be a little overwhelming for a newbie I guess.
I used to roll my own boards for ATmegas, now I just use Arduino boards, price is more than the processor, but cheaper than rolling the whole board yourself unless you do it in numbers, the Arduino hardware is the best way to go if you're talking quanities less than 10 for sure, probably cheaper all the way up to the 100s if you're hand assembling.

They only existed in the 80s because the device manufacturers had no way to distribute large multi page paper documents for free. Sure, if you were a Genuine Degreed BS-EE with the job title to match, salesdroids would pretty much send you anything you ask for as samples. The general public, believe it or not, was expected to actually pay for printed appnotes and even printed datasheets.
Nowadays, if you want to learn how to make sound, or program a LCD, or run a A/D converter, you just download the appnotes from the manufacturers website, typically you get a PDF explaining in great detail how it works, schematics, and example code to get you started out. Some manufacturers go further and sell demoboards for a really modest (probably subsidized) fees.
Either the manufacturer's appnotes are so simple and clear that a "D" student could figure it out, or they go out of business and are replaced by a manufacturer with better tech writers. The quality level is generally excellent.
