(The screenshot above shows some benchmarks just to give you an idea of how fast the Raspberry Pi, even through emulation, is running DOS.) A homebrew coder who goes by Pate just released his rpix86 DOS emulator for the Raspberry Pi platform. The emulator offers support for Super VGA graphics, Soundblaster 2.0, memory, USB keyboard and mouse. Pate’s previous work includes a DOS emulator for both the Nintendo DS handheld, and the Andriod OS.
This project is a result of needing to service a domestic electronic item without being able to obtain a circuit diagram. The process proved to be very long and painstaking, but also very rewarding. The steps presented here are not exact, and you will no doubt find your own way of working which is more effective in the case of any particular board. However, I believe the basic procedure is essentially correct for the majority of boards which are too complex to reliably hand trace. Without the need to invent the process, things should progress more quickly. For simple boards, it is probably better to use pencil and paper to draw the board onto squared paper, replacing components with their symbols, and changing track crossing places to avoid components.

Tom Lehmann's NY Style Pizza
Today, I made yet another pizza based on Tom L.'s NY style pizza dough recipe. This time, I decided to use a hydration level of 60 percent, and to use an amount of yeast (IDY) at the upper end of the range called for in the recipe. It may be recalled that in prior efforts I used hydration percents at the lower and upper ends of the range (58% and 65%, respectively), and yeast levels at the lower end of the range (about 1/8 t. IDY) and far outside of the range (about 1 1/2 t. IDY).

50 Things Everyone Should Know How To Do
Email Self-reliance is a vital key to living a healthy, productive life. To be self-reliant one must master a basic set of skills, more or less making them a jack of all trades. Contrary to what you may have learned in school, a jack of all trades is far more equipped to deal with life than a specialized master of only one. While not totally comprehensive , here is a list of 50 things everyone should know how to do.
The old inkjet printer had to go. Got two nice stepper motors out of it. I don't like the noise and dust from a rotating cutting tool, and became interested in budget lasers. In my search I've taken a good look around on Ebay, and found several "power lasers". After some investigation, they are identified as 200mW red laser diodes from CD- RW or DVD-RW drives.
Using a CD / DVD RW 200mW laser diode for cutting foam?
Getting samples
It's hard to go wrong with free. Parts manufacturers are often more than happy to ship you, for no cost, a few samples of their merchandise. They often ship within the week, sometimes the next day, and with free 2-3day FedEx/UPS.
