Roque, those errors at the end are what happens when you don't have a target device connected. It is failing the target device ID because there is no target (of course), and failing the self test because it's trying to measure some voltages from the target board. If you go into the settings...
KaZaaD, if you read the 'desc.txt' file included in the zip for the PiCS rev B design, it says to make sure you disable MCLR in the configuration settings when you are programming the boot firmware onto the 18F4550, and as long as you do that you don't need the pullup resistor on the pin. I...
Okay, this originally started out as a post asking for help on diagnosing my problems, but I think I managed to fix it myself just after posting. So I've edited it just to put my solution out there for anyone with similar problems:
My ICD2 clone (PiCS rev B, from www.icd2clone.com) worked for...
I apologize if this has been mentioned previously, but I was unable to find it... For the PiCS version of the clone which I see over at icd2clone.com, does anyone know the manufacturer and model # of the plastic enclosure that it is designed for? (the one it is pictured mounted in, in the...
I am using switchercad, but for some reason never thought to take a look at the examples. thanks!
**EDIT*** wow, those examples really took care of everything. there were 2 examples that both fit my requirements nicely. thanks again!
I am going to build a boost converter soon, just using the standard topology.
however the last thing remaining to be determined is the inductor size.
i can run the thing at anywhere between audio frequency and 100+ kHz, whatever works out best... but I don't know what inductor value to use...

I am looking for a DC-DC converter design that takes a nominal 12v input, and outputs 12v also. The input voltage should be 8-15v or so... the lower the minimum, the better (6 or 7v minimum input would be great).
I need at least 2 to 3 amps output, the higher the better... 5...
the OPA603 appears to be obsolete, according to the TI website. thanks though, I will look around the TI site for a similar one, so I can have a high-frequency amp too.
You, sir, are my hero. I never even thought to look for a single-chip solution. I had envisioned some sort of complicated circuit with push-pull MOSFET outputs or something.
with a slew rate of 9v/uS that should be capable of a triangle wave at 250 KHz at 18Vp-p (by my quick, offhand...
I am working on building the function generator project from EPE magazine. However, the output of it is AC-coupled, and across a 10k pot for voltage adjustment, so obviously the output impedance is pretty high. I know that a function generator output is generally not used for low-impedance...

Not exactly a complete guide yet (still needs some more pictures, etc) but that's my little tutorial for how I make PCB's. I can get right down to surface-mount parts and traces between pads with little problem, all without any special equipment besides a laser printer...
Re: Paintball board design
**broken link removed**
that is my marker, for which I have done two separate control boards over the course of its construction. The first question I have is: how experienced are you with electronics? there are two totally different routes you can take with the...
