a little help with capacitive power supply values

[Pic_User]

You are right. Last seen, June 2006.

You expect to see people disappear from threads labeled:
Interfacing AC power lines....
...transformerless DC supply...
How to design without opto-couplers ...
How to measure high voltage while standing in a bucket of water...

But not from a thread labeled, “AT/PS2 Keyboard - PIC Interface?” ?

Then again we have to consider his user name!
Kamikaze47 where are you??

Deafening silence defined is :

'A silence or lack of response that reveals something significant, such as disapproval or a lack of enthusiasm'

Definitely some valid chirps :-) apparently apparitions do re-appear and it's not all smoke and mirrors :-).
Now I'm wondering if you have are planning to interface and AT/PS/2 keyboard to the AC mains line that delivers a different 'ZAP' at each keypress ?? Could it be solar-powered or we gonna just stick to the original hookup to directly the substation on 3-phase ?

The silence in this thread has me a little worried too since i haven't seen Steve around since I asked about some possible measurements (In the post before he said he wasn't to do a few measurements 'cos of his trusty isolation transformer ), I haven't seen any activity on this thread from him since then.
And all of a sudden this thread went extremely quiet...!

Shocking I tell you !

Kind regards

Hey Dennis!
I'm still lurking about, but it seemed like you have things under control and I don't have a whole lot more trouble to stir up....

Besides, I've been seriously swamped with work obligations, family obligations, personal projects I'd like to complete soon, and now we've had a LOT of rain here in the last couple of weeks and I've been spending some time keeping our steep hillside property under control. Been spending a lot of my free time with a shovel, cleaning ditches and culverts and keeping 800 feet of gravel driveway (with 140 feet of elevation gain and 2 switchbacks) from blowing out....

I figured to just take care of chores, quietly watch the forum, and wait for your final schematic and report.

Do you really need some measurements from me? If you've got something specific in mind I'll see what I can do. But you seem capable enough and pretty well in tune with the safety issues...

Steve

No prob's at all ...
Two things :
1. Hadn't heard from you so I was a little concerned
2. Regarding the measurements .. was taking a deep dig 'cos I saw you got a new 'scope :-)

Well that's a mighty kind offer :-) and I would love some waveform captures from my PSU since I don't have a 'scope anymore .. but no stress at all , will pop down to a friends spot to get those :-) but only once I have built the others ...at the moment time is an issue
Will be posting some results and more info soon ..watch this space !
Keep well

Dennis
