'[PIC]: In Search of Power Supply for P16Pro'

Good afternoon

Quick question, hopefully someone out there can help me.

I just was given a P16Pro, but I don't have a power supply for it.  I
was wondering if anyone either has an extra power supply for it, or
knows where I can find one that doesn't involve paying a shipping charge
which is worth more than the part.  It needs a 17-30 VDC or a 13-20V Ac.


If anyone can help me out, feel free to email me @

Thanks

I got a 13.5/30V PS at RadioShack (like a big wall wart but with a cord on
it) that puts out 1A and I would NOT recommend it as it actually puts out
~35V at the load the P16PRO draws (at least while idle).  I noticed the
little TO92 regulators on the P16PRO were getting pretty hot but when the
7808 exploded I knew something was wrong. ;-)  After replacing a burned
transistor or two and the two regulators the same thing happened again and I
realized that my "30V" supply was more like 35 so I soldered a 7824 where
the connector is supposed to be and hardwired my PS to it.

Moral of the story - Radioshack PS may be OK but stick to the middle of the
acceptable voltage or regulate it again.  Probably the cheapest thing to do
would be to just get a step down transformer (probably could get an
appropriate one at 'the shack') and use the rectifier on the P16PRO but I
can't vouch for the goodness of this approach.  Should be fine though - just
be careful...120VAC bites.

Just modify a normal 3V-12V DC adapter to an AC type, or better still tap
out an additional pair for the AC output.  This would give you a general
purpose adapter, so get a larger rating one.

Hi. I can offer you one 18.5 V @2.7A DC switched
power supply for a total of $20 USD incl shipping world-wide.
You just need to add a power cord according to your local standard.

You can take this of-line if you're interested...

(I've lost track of who the O.P was...)

Hi. This is a little O.T. but related to the post below...

During the latest couple of days, I'v got a lot of
posts out-of-order. *This* came right now, a couple of
hours after I got the *first* reply.

Anyone else also seeing this ?

Regards
Jan-Erik

Yeah, I have come to expect this of the 'net these days. There are so many
potential bottlenecks that I have found messages sometimes get jammed up for
quite some time.

an example I had recently through a Yahoo message list went like this.

Sent message from home to list on Tue @ 23:10, eventually received through
list on Fri @ 04:05
Not seeing above message from list, sent another one from work on Wed @
17:30, eventually rec through list on Fri @ 04:05
Friend on list replied, his message sent Fri @ 04:07, I received through
list @ 04:08

My home ISP is totally separate from the university network I am on at work.
I have come to expect these sort of delays now. I know there are lots of
messages sent to the various lists I am on that I do not see, they just get
lost, and I only become aware of them when I see a reply to the message.

That's the nature of something this distributed.  I've actually received
replies to my messages before receiving my original message back.

In the last few days I've noticed a higher than usual number of threads that
I never see the original of, just replies.  Of course that could just be a
rash of bozos not tagging their original posts correctly, and someone who
has untagged or OT enabled replying and fixing the tag.

Even worse: I've received replies to my messages before I sent them!
