Re: ESR meter upgrades

Yes

For the extra money i wish i ordered this now
http://www.ebay.co.uk/itm/2221248490...%3AMEBIDX%3AIT
if i get a refund for my kit i will purchase one of these then i can send the values too you etc.

Cheers!
Do note that the original seller you bought from (At least the one you linked to originally)
Also sells it assembled.
So he really should be able to get you either a schematic or at least a picture of it assembled

ive emailed the seller a few time all he says in the return messages is "so you cant weld this" i think he means solder it and he has no schematic ive asked twice and to confirm one of yesterdays post i made

sorry about the confusion (was one of those days yesterday nothing went rite) i misscounted the ebay picture and now just re checked the kit all again yes there are 24 spots on my pcb and 24 resistors fitted on the ebay picture yes just counted ny resistors again 23 plus 1 zero ohm (which isnt shown in any ebay pictures) but without any schematic im still stuck anyway.

Re: ESR meter upgrades

Ok, incase you did not notice the picture in his eBay AD is not of the item he sells.
They are watermarked "kiss_buy".
That seller does have the same meter for sale, search for "ESR 2016" in his eBay store...

Re: ESR meter upgrades

I hope the banggood kit has instructions!

Thanks i have just noticed that too.

if you look really closely at the pcb you can see it has the parts printed on it so your fine with that kits thats a good price too i keep forgetting about that site.

Good point!
Thanks.

Re: ESR meter upgrades

post pics of both sides of the pcb that are good enough to see all the tracks clearly.
i'll work it out for you.

stj if you mean mine i will post some asap as light here at the minute is too bad too take any good ones, so bear with me thanks.

Re: ESR meter upgrades

i almost finished the pcb stuffing list,

verify something for me.
x2 110 ohm
x1 5.6k

are you sure about those - specially the 110ohm - is it actually 1k?

[vinceroger69]

Re: ESR meter upgrades

x1 5.6k measures 0.56 on 20k scale
x2 110 ohm measure 1k my mistake sorry
x1 2.2k is 2.2k (im not sure if i wrote this as 2.2ohm)

[stj]

Re: ESR meter upgrades

wouldnt .56 be 560ohms?

[vinceroger69]

Re: ESR meter upgrades

Resistor colour GREEN BLUE BLACK BLACK BROWN cheers for your help stj just checked using hobby -hour calculator 560 ohms

Re: ESR meter upgrades

thought so.
in that case - go build it!

Big thanks for your help stj i wont be able too get back too this project untill early next week as going down the coast to visit dad (fathers day) suprise etc if weathers nice may spend a few extra days but will update this thread when built.

sorry i forgot too post this yesterday
c5 and c6 are 100uf 25 volts in the kit
then i have x4 104j
x1 103j

cheers again stj for your help

Re: ESR meter upgrades

16v was a minimum figure,

104 = 100nf
103 = 10nf
