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 made for myself this ESR meter.
It cost me 20 euros.
Works very well

Hello,Agent24
He can really MEASURE,and not an approximate estimate,as many ESR meter.
This is really impressive
If there was a desire to do,try to help as mush as possible.
Scheme itself is not complicated,higher demands are made only to the radio components,and it is clear.
I also hope to repeat it.
Already started to collect radio components.

Good luck

Re: Any experiences with this ESR meter circuit?

If it can accurately measure down to 0.0001 Ohm that is quite impressive (to me anyway!)

Pity the thing is in Russian and I can't read it.

Google translate got about 10 paragraphs in and then called it quits...

Hello all
Perhaps somebody will take over here this project.
I think this is the first attempt at an amateur level,to make a digital ESR meter with a resolution of the 0,0001ohm.

Re: Any experiences with this ESR meter circuit?

I've already built a 'Blue ESR meter' for myself but this circuit looks pretty nice too (perhaps inspired by Bob Parker's design?)

I thought PICs could be programmed directly with a serial port and only 3 wires?

Re: Any experiences with this ESR meter circuit?

Why not use a basic stamp from parallax? very easy to program , they also make the propellor chip which look's very interesting.

Re: Any experiences with this ESR meter circuit?

and i gave up on it because i'm just extremely cheap about some things...like the things i already have(my analog diy meter is still working) or things i can work-around (i can measure capacitance with analog ohm meter, it turns out...not terribly precise, but precise enough to see what's going on...).

now i'll probably buy cheap soldering station and one more iron within that price....
hehe...

but if i was looking for built esr meter today, i would buy mike's esr micro, yes.

sam, perhaps i'll send you few badcaps so we can compare readings, me on my analog meter, and you on esr micro...

Good idea ,that would be interesting seeing what the values were .

Have a merry xmas

Re: Any experiences with this ESR meter circuit?

I have ordered mikes micro ESR v4 meter and the price is very good and value for money.

Has anyone build this esr meter?

source code:

I have maked pcb and all parts, but I can't compile source code in mpasm.\
If anyone has hex file, please post it.\ Thanks :-)

Re: Any experiences with this ESR meter circuit?

What about his Trivial High Voltage Programmer version using the CD4050 CMOS ?

Any success building the ESR meter ?

i wonder how many people masturbate on company time, ie get paid also?

>masturbate for a few seconds to wake myself up

yeah, sex instinct takes precedence over just about anything..even when you cheat..hehe...

Re: Any experiences with this ESR meter circuit?

I bought my Atlas ESR+Capacitance meter for ~65+vat+p&p, comparitively, to food for example it doesn't seem that expensive, and it still works after eating it.

When I was hard up but wanted luxury goods, I just adjusted my budget.

To buy a new 4 head Panasonic VCR back in 1998, I spent two months eating 16p a loaf genetically modified bread and tap water to pay for it, to stop myself from passing out from starvation and feeling like crap whilst working, I'd go in the work toilet and masturbate for a few seconds to wake myself up, the hormones produced helped alot and after the mission I owned that VCR, more happily for knowing I almost died for it.

Re: Any experiences with this ESR meter circuit?

Anyone tried making one of these? I've got just about all that's needed except for the actual PIC used in this design, but seeing as they are cheap I'm tempted to give it a go...

Re: Any experiences with this ESR meter circuit?

Yep, goto`s & nop`s aren´t anything to be proud of and not the way this should be done.
But sure, resources are limited on such controllers, thus sometimes the ugly is the real beauty.

Re: Any experiences with this ESR meter circuit?

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

I know the feeling as well. I have to dig up some information about PIC programmers. It was fun playing with the micro's at uni. That is why when I have spare time, I want to get into some PIC (or any other micro-controller) programming.

You should go through the program as well. Make sure it works well and if anything could be done to improve it (maybe that will be after you get the initial design working ). For example this quote: "Calibration is by adjusting the delays inside this loop, by padding it with goto's and nop's.". I really do not like this sort of approach. It would be much better to find an alternate way that is more flexible to achieve the same result.
