channel-channel isoalation	30 Dec 2004 22:04 GMT	1
I give analog signals to 8 input channels then i convert it to digital form using ADC then i give this count to microcontroller. i.e....\|iso amp\|--->\|\|-->\|ADC\|-->\|opto isolation\|-->\|uController\| can i get good accuracy?
Protel 99SE	30 Dec 2004 07:24 GMT	4
I'm drawing up a power circuit, the footprints and all the rest are all ok however when i update the PCB there are errors generated around the diodes saying: ERROR: Node not found. When i take the diodes out the circuit updates without error. All the foorprints libraries are
Experiences of the Electra autorouter...	30 Dec 2004 07:00 GMT	3
Has anyone here any experiences to share about the Electra shape-based autorouter ( http://www.connecteda.com)? It seems very reasonably priced and is apparently written by some of the Spectra team...
Easy-PC to Circuitmaker Conversion	27 Dec 2004 22:25 GMT	10
A very, very long time ago, I bought the original DOS version of Easy-PC out of an ad in Ham Radio magazine. With all respect to the current product, that old DOS sucker was about the buggiest thing this side of Microsoft. At any rate, the LAST board I laid out in the Easy-PC is ...

OK.... after all that wuffle about the distinction twix open source and shareware, give me one well known organisation using "open source" PCB layout tools on mission critical projects...? I'm waiting.............!
4069 as an amplifier spice model?	23 Dec 2004 11:56 GMT	4
Anyone know of a spice model for a 4069 buffer being used as an amplifier? If there is one in pspice I can't find it. Or come to that, info on what the params for a 4069 used as an amplifier are.
Newbie - Trying to simulate 3.5MHz Xmtr - LTSpice	23 Dec 2004 05:18 GMT	1
I have never used a schematic capture program before and I am just getting back into electronics after many years, so I'm a bit rusty. Please bear with me. I am trying to simulate a low-power transmitter in the 3.5 MHz range in LTSpice. I would like to look at a plot of the ...
Protel Schematic to PCB	22 Dec 2004 21:12 GMT	1
I am just starting with Protel DXP. I have put together a small schematic and have created a net list. How do I get that data into the PCB tool so I can route the schematic? Thanks
