Any experiences with this ESR meter circuit?

Re: Any experiences with this ESR meter circuit?

did you build it?

not yet.
last time i didn't have any rs232 level converters lying around so i used a simple low voltage parallel PIC programmer.
i couldn't find a decent burn tool that supports that simple programmer, and the one I used was rather crappy. somehow I messed things up, I guess. i'm not sure if I fried that PIC, and the whole thing has gone to the "unfinished projects" box for now.
I have the parts for a serial programmer now, so once I've passed that nasty oral exam I'm currently learning for I'm gonna dig it up and give it another try.


@gonzo: that first ELV circuit really looks good. i might give that a chance, too.

after all I'm a poor student.

I feel ya. Frustrating when people suggest expensive kits when they know we are poor.

May be this one suites your needs:

I think the DIY kit is not bad and not that expensive.

If you are not on a budget, this one would although make fun

I've no idea on that one, haven't seen it before.

you are going to need a pic programmer of some kind and if you are working from that page ASM you will need software I guess to create a burnable file
(not sure how they do it these days)...Its been a very long time since I looked at any of this type of stuff so I am not up on how and whats being used these days.

There is heaps of info out there on programming them and chances are you will find some freebie software or methods to use.

search on that PIC number you are using also

here is a pdf I found its on the 16F84 (I think these are way old)

But should help you work out things you will need to track down.

old again, el cheapo programmer for the above

here a few pages on the type you will be using

http://www.oceancontrols.com.au/micr...rogrammers.htm

http://www.olimex.com/dev/pic-pg3b.html

sure there's a lot more out there and probably user groups in your neck of the woods

Someone here may possibly have better info thats more applicable to what you need kikkoman.

Good luck with it, keep us posted on how you go with it

HTH cheers

Re: Any experiences with this ESR meter circuit?

I decided to build that thing.
Just ordered a few components, but I already have most of the stuff, so it's gonna be cheap - unless I fry the PIC (which is the most expensive part).
I have absolutely ZERO experience with PIC programming, but you can't fail without trying.

It is on the main site, forgot to post the link:

Re: Any experiences with this ESR meter circuit?

looks cool.
only problem is getting the code for the pic.
i didnt see any link to download it.

I finally thought it's time for an ESR meter, but it's hard to find any here, and shipping costs from the US unfortunately are often ridiculously high....and after all I'm a poor student.
Yesterday I stumbled upon this schematic, and it looks pretty decent, since it also measures capacitance and has a 2x16 LCD display.
has anyone here ever successfully built this one?
Any opinions welcome.
