Re: Transitor/ESR tester dead

How easy is it going to be to fit a usb socket and any missing parts to the tester? i havnt found any information about doing this?

[stj]

Re: Transitor/ESR tester dead

the usb socket is nothing to do with it - that's just for charging a lithium battery - you see this model on ebay.

programming is done through a 6 or 10 pin header.

Re: Transitor/ESR tester dead

used in conjunction wih this:

supplied dirt cheap and improved by our friends.

i actually built one on stripboard before i noticed them on ebay, it cost me about 5 times the price to build!

here is the schem of the superior chinese one!

Re: Transitor/ESR tester dead

cool ive just found this thread a very long read but does cover these testers too and has the same info you have just posted i wondered what the usb solder tracks was for thanks for the clarification

page 11 shows the socket you have mention fitted

Re: Transitor/ESR tester dead

btw, i just ordered this model.
i chose it because it has a 3pin connector and flyleads.

I just ordered one too.

BTW the leads aren't included.

Re: Transitor/ESR tester dead

this one does but extra £4.00 you can probably buy the leads/clips cheaper

Re: Transitor/ESR tester dead

the leads are included, just not the clips on the end.
because mine is here!!!!
and i made some nice protection for it from a fucked lcd panel & some threaded spacers - pictures later!

btw, the firmware has the extra stuff compiled in it, if you hold the button down you get a menu.
then you can activate the frequency generator or pwm generator!

i tested the frequency generator with my multimeter that goes upto 10Mhz and the output was accurate

Re: Transitor/ESR tester dead

some pics with my acrylic shield.

i made an error in taping the battery down,
i'm going to get one of these for it.

Re: Transitor/ESR tester dead

That's much coolness. I won't get mine for 15 days at least. All those I saw shopping online couldn't deliver any sooner though and the shipping was free, they all ship from China anyhow so what's the diff? Maybe I'll get another cute little Chinese trinket!

Re: Transitor/ESR tester dead

way ahead of you,
i'm waiting for this now!
http://www.ebay.co.uk/itm/141694353386

it's a clone of this:

and by tweeking the usb i.d.'s it works as one of these!

damn i love this stuff!

[SteveNielsen]

Re: Transitor/ESR tester dead

I hope I get a Chinese trinket. I love those things.

I won't bother repairing this old tester, BTW.

[stj]

Re: Transitor/ESR tester dead

you should fix it just for the challenge.

[SteveNielsen]

Re: Transitor/ESR tester dead

I agree in principle but my bank account says no.

[SteveNielsen]

Re: Transitor/ESR tester dead

I got mine yesterday for $16.95 from AliExpress. Very cool device. I'll mount it on plastic and put some clips on the leads. I've only tried it once and the display is so much better than the old one. It was worth it just for that alone.

Re: Transitor/ESR tester dead

well i soldered a programming header on the bottom of mine yesterday, just waiting on the rotary encoder now.

[SteveNielsen]

Re: Transitor/ESR tester dead

What rotary encoder did you order?

[stj]

Re: Transitor/ESR tester dead

What rotary encoder did you order?

the expensive (relativly) one that looked better made.
http://www.ebay.com/itm/231241921964

it may not work right without changing the firmware though - we shall see.
that's one of the reasons i soldered the 6pin header on.

i will also add a usb-port for a pc client program that may ID transistors from a database in the future!!

Re: Transitor/ESR tester dead

Wow, stj, thats some major coolness! Keep us updated on your progress, Ill probably follow in your footsteps...
