Sorry I did not have more time to specify... at the bottom of that link in the comments section tere was info on orders from goldphoenix... "Because Gold Phoenix can do down to 7mil for a two-sided...

Hi Bruce,
I havent yet ordered from Goldphoenix but some of my friends at http://www.happylab.at/ have... They seemed to be content and from what I saw the boards looked decent... Dont forget to...

Hi Mike,

Sorry for the late reply, and thank you for all the great information and the great links...

I'm sure I've had several past projects with badly mounted piezos, and
thanks to this...

Am I the only one confused by the "ALL_INT -- Global Interrupts" interrupt source?

Hi! I got a chance to look at your singing ballons on youtube... nice...
I'd actually be quite content if I reach that volume... You wanted them even louder?

Hi Mike!

Thanks for the post... I worked on a very lengthy reply and then lost it unfortunately =(...
The main pointers of that message were:

I'm looking for a small solution that can run on...

After some thought, I think I will go with max232/3232 or equivalent. May get back to this if sound output is not satisfactory...

Any information regarding the last question would be great to know in advance:p

Hi, thanks for the reply. I believe I stumbled upon that image when I started the thread. Together with these 2 attached images (from microchip datasheet), I had tried to figure out where exactly...

Thanks! I've glanced through it and it's the best info I've seen sofar. I'll need some time but I'm going to work on a simple solution for pics (need to read up on inductors etc). Seems like this...

Unfortunately no part number... just a bunch or really fine coils... I tried to be careful but I cut through them.... Perhaps I'll buy another unit so I can find out how many coils etc... but I guess...

Never posted my thoughts....
the method woudn't work because the Ansel bits (which select the channel the sampling cap is connected to) don't allow for the sampling cap to be disconnected from all...

Every so often I find myself buying products just to find out how they work... Recently I bought a cheap battery powered Piezo alarm...very small and quite loud...

? toggle command is only good for port pins ?

Sorry... please ignore 2)))

Hi Alain!

without checking the datasheets or functioning code snippets
my idea was the following:

only 1 channel for cap touch (example on a 12F)

Sorry, I've been quite busy and never got back to this... I had wondered why, in the above mentioned appnote (ww1.microchip.com/downloads/en/AppNotes/01298A.pdf), 2 channels are needed (and if it's...

I remember reading about a similar problem a long time ago. I believe the problem is that the file name length which the program uses to differentiate/recognize files(.bas or .inc) is quite...

Thanks you for replying. I'm not having problems on the software side... I've used the ADC module quite often without really grasping some of the inner workings...(for that I simply select the...

Hi! I've been cathing up on theory, and have questions regarding the inner/electrical workings of the ADC module and Chold (Sample and Hold Capacitor).

reading through various documents (for...

I ended up using the 250 Ohms... (I'm working on some open source hardware (sparkfun widgets) which can be reprogrammed by anyone.) I really like the idea of the Pic self destruct routines. That...

Thanks! ...Hadn't noticed because the main routine wasn't doing anything, and the other Led still seamed to toggle at 1 Hz...

Hi,
In one test circuit I have a voltage (0 -1.6volts) going into the PIC ADC directly.. Although this works well, I suppose its safe practice to put a resistor (under 10K) in between as a...
