If there were no copyright in the first place, there would be no need for copyleft, and all software would be free software.
The GPL requires copyright law to guarantee that people have access to the source code for all GPL licensed programs. Without copyright law, there would be no way to enforce this.
When GPL code is modified the modifications can not be closed. However BSD licenses allow programmers to close the modifications they make.
As the copyright holder for your code, you can choose to distribute your code under whatever license you please (unless you are distributing a derivative work of somebody else's GPLed code, in which case you are restricted to the GPL).
Neither the GPL nor the BSD licenses give you the ability to prevent people from distributing code you've already provided to them under those licenses. No matter what licenses you've previously provided code your own under, you're free to release that same code under whatever other licenses you please.
BSD protects my investment. If I invest tyme in programming and use a BSD license I can close my source code preventing others from taking it and giving it away. I can not prevent that with the GPL.
You hold the copyright for your code; you can license it however you please, irrespective of whether or not you have previously distributed it under the GPL.
You can't retroactively change the license of code you've already distributed to people, but you can't do that with the BSD license either.
Things are different if you accept external contributions without requiring copyright assignment, but you shouldn't be closing the source for a project in that case anyways.
Why didn't they just put a nice simple low-pass filter on the output, instead of trying to get cute and put it in the emitter lead? And shouldn't there be a diode in there somewhere, to extract the waveform's envelope?
Assuming I've read the documentation correctly, the capacitor and RM don't form a low-pass filter. They serve to increase the gain of the amplifier at higher frequencies. The capacitive reactance of the capacitor decreases as frequency increases. This reduces the impedance from the emitter of the transistor to ground, increasing gain.
The 100K pot was adjusted until the voltage across RE was 3.3V, as specified. (This happens with the top end of the pot at 4.4K).
I believe 0.33V is the voltage specified in the instructions.
You can actually buy an adapter, the XFPS [www.xcm.cc], for 360 that converts a M&KB setup into a regular controller for games that don't support it directly
The mouse control with those adapters is universally sluggish and terrible. There is no way to get decent mouse control on the 360.
gave Baldur's Gate II a try and actually enjoyed it for a time..until the vampires came along who hit you with the double-whammy of "speed" and "level drain" all at once. After dying and reloading about a thousand times I realised that this was just not fun.
There are a few items that protect from level drain, the 'amulet of power' being the easiest to get. In addition, clerics get a spell called 'negative energy protection' that grants immunity from level drain for a short duration. Failing that, summoned monsters can be used to tank for your party while your spellcasters pound the vampires.
There are also several cleric spells available that make short work of vampires, 'false dawn' and 'sunray' being two I recall very well. If you have a cleric of a high enough level, s/he will also be able to use 'turn undead' to destroy vampires.
I'd recommend giving the game another chance; it becomes very entertaining once you come to grips with the game mechanics.
