CHAPTER 12: CONSTRUCTION TECHNIQUES - I susupect quite alot of the people bad mouthing the art of electronics never got this far. Also: Apendix E - how to draw scematic diagrams. Also chapters on how to use osciloscopes. Also a large practical microproccessor project that nicley takes quite alot of the bits learnt in previous chapters and wraps it together.
Art of electronics is very good it does need an update though! If you follow it through from start to where finnish though (buying legacy hardware along the way to try things out) you will find yourself very competent handeling moden electronics because they are in genral far easier to deal with. If you compare a moden 8bit microcontroler for example with having to design your own microcomputer system to do the same job then you are in orders of magnitude easier teritory. The art of electronics along with the internet will get you very far. Also rember there are lots of free electronics texts on the web specificly: http://www.pmillett.com/ and maxims and analog devices websites have loads of interesting articals.
But debian stable rearly is stable everything has been in testing for a while and definatly works in almost all cases. Most people should run debian testing. Debian unstable also lives upto its name. cutting edge packages that may not have even been tested by the people uploading them! I tried running debian unstable once to see what would happen and the result (predictably) was massive data coruption after a day or so. On the other hand debian stable is like a rock.
I second your comments about scope I ended up buying a 35year old analog one instead of a new digitial one because the analog one had 1mV/Div twin channels. 4 coupling modes and lots of different trigers. I also ended up spending about the same in two probes as for the actual scope which is something people often mistakenly skimp on.
20MHz TTL level signals don't require anything special as I have built projects on breadboards with connections spanning the legnth of multiple boards carying 20Mhz clock signals and 10MHz clocked delta sigma modulated bitstream.
I would aggree though that I would probobly use a PCB for anything faster than that.
Most of you have not seen it

Iron Man Released
·
· Score: 2, Interesting
Well I just got back from Iron man and have to say while it's clearly not the best film I have ever seen it was well worth seeing it and it managed to portray the US armed forces without the usual silliness. Also unlike some films it all made sense at the end (leaving a film unffinished is so old). From the entery of bladey you could pretty much see the exact story. I particualrly liked the very ended as it was not the expected romantic thing that seems so sterotypical.
tl;dr see this film if you are going to see a film
Well even if this was an ARM killer Apple don't have anywhere near the fab capacity to produce the arm chips that are put EVERYWHERE. You cna buy 5$ micro controlers with ARM cpus, you can buy massive FPGA's that have arm cpu's intigrated. Your DVD player probobly has at least one... hell nowerdays your mouse has a god chance of having one.
Some of you saying onboard sound is aceptable clearly haven't had the pleasure of the likes of: ASUS A7V8X-X and Foxconn GMX boards which have terible terible sound that makes creatives driver problems look tame and come complete with crackles @ disk access and mouse movement. I currently have a crative 24bit sound blaster it sounds pretty good works with ASIO4ALL and linux and cost £4 inc P+P from ebay. I would rather have a pro audio card but they are far more expensive and only marginaly better quality.
For those not into RTFA here is a summary:
Proudest moment: Dodging the chair as I ran out the door
Details Behind departure: DEVELOPERS, DEVELOPERS, DEVELOPERS... need more be said?
I haven't even started a degree yet and I could kill alot more people than the very amaturish attempts I have seen from religious groups and the IRA and probobly not get caught and not die in the proccess. The reason I doun't is because there is no reward for killing people and a large amount of risk.
I buy very cheap motherboards and the sound chips often have terible drivers and have interferance caused by things like disk access. They also cause games to be less smooth, the FPS drop is not but about 5% but they seem to cause alot of momentry pauses (porobly overuse of interupts) which are very annoying. I am actualy using a 24bit SB live! at the moment and it's the best card I have ever had with very good midi and drivers, also it can output 96KHz 24BIt you just have to install the component of the dirivers that lets you set the sample rate and word legnth and use ASIO4ALL... but I have no end of trouble from SBlive GOLD/Values and Audigy cards.
I rember reading about how this stuff would happen back in 1995 when I first heard about paladium (fore runner to "trusted" computing). At the time my attitude was nah never... but now graphics cards are activly marketed on their DRM support (HDCP)and MS wants to rent you an OS. I do hope slashdot is able to build there own computers?
anyway here are some links with scematics and such like you may want to save to your hard disks before all non TPM hardware is outlawed:
http://www.zxdesign.info/indexPage.shtmlhttp://www.hanssummers.com/computers/newz80/index.htmhttp://www.homebrewcpu.com/
btw does anyone have the specifications for PCI? as you apear to have to pay a huge huge sum of money to get them and be connected to the right people.
"how that thermal vibrations have an extraordinarily small effect on the electrons in graphene" does this mean that graphene transitors will have HFE as a stable paremeter?!? that would be seriously awsome!
excelently put. In the feild of my study there is know way I could reach the highest levels of understanding without a degree as the information is very hard to aquire otherwise.
for me the big of 3 sci-fi were asimov, philip k dick and clark. Now the last of them is gone I feel greatly saddend. All of them have inspired me greatly.
Second verilog it will blow your mind certinaly did mine when I first rearlised that everything kind of goes on at once. I have only just started out learning it due to having to keep up with my achidemic studies making me tired but its good fun:D and you get to watch your projects on your desk if you have an FPGA dev board.
I have just made a slashdot account to reply to you. I run debian lenny with xwindows and fluxbox. It has more features and programs avaialble than windows vista, it also is far more configurable and runs on a far wider range of hardware. I run it on my laptop for: Software development, spice simulation, word proccesing and web browsing. Due to been a poor student my laptop has the following specifications: 266MHz P2, 160MB of EDO memory, 4GB HD, 8MB S3 virage graphics, and a nice 3com PCard NIC. Using debian this is a very usable machine and I frequently impress people with how pretty my fluxbox setup is.
So to me 2GHZ cpu and 2GB of ram is INSANE just to be able to run an OS. To me no OS should use more reasources than a slimed down linux setup unless it has features that need those reasources... which vista dosn't. Hell we used to play full 3d games on the same hardware as my laptop and an OS!

flares too goodd for you son? back in my day we had to make do with smoke signals!
Does CAE linux have any circuit simulation/pcb design tools? it apears to be only mechanlical and genral engineering simulation.

your hardley going to get an objective veiw.
Philips PM3232 not to sound like some outdate product venodr of some kind but the trace is ultra stable and sharp aswell.

not evil just still dosn't have a clue!

I find it amusing that they think the raptor should have the greatest power consumption when it has SMALLER platters than any of the other drives.
