ESR meter upgrades - Page 48

**Per Hansson** · 05-06-2018, 06:25 AM

I have uploaded the firmware from one on eevblog.
Yes it has a menu where you can select the basic modes of operation, including only ESR.
If anything's missing just compile your own

@STJ,
Did you investigate the AY-AT firmware further? (See message 928)

**stj** · 08-13-2018, 04:22 AM

no.
and that machine is sketchy as fuck - i think a harddrive is failing.

Hi i was going to arder AY-AT tester with case but seen a post where it says this one maybe a better choice and is newer https://www.aliexpress.com/item/M644...ceBeautifyAB=0
can this tester be upgraded with later firmware etc if needed and has anyone found a case too fit them thanks

ask here:
http://www.eevblog.com/forum/testgear/$20-lcr-esr-transistor-checker-project/5025/

it looks o.k. but a colour display would have been better.

Yes true no colour screen on these, so a ay-at it is then as aliexpress has a sale on and these can come with a case etc, too save me reading loads of pages in the eevblog thread lol, do you know what if any parts are recommend to swop out? before i update the firmware, i will also keep too a 9v battery as fits in case nice.

**stj** · 08-30-2018, 02:24 PM

only the voltage reference really, like last time - i think you have spares of the lm4040

beware of the case, if it's the acrylic ones they crack.

**stj** · 08-30-2018, 02:26 PM

btw, i ordered one of these in the sale.

i'm thinking with a mask on the end to reduce the aperature, i can check how hot chips are without using the "finger test"

yes got spares of the lm4040 so thats ok what crystal does the ay-at come with is it worth upgrading? and yes that looks like a good ir thermometer i will have a good look through there site whilst the sales on, i was going too make a post asking if anyone had spotted anygood bargains etc we all like too build our test equipment/parts stock up.

**stj** · 08-30-2018, 06:55 PM

upgrade to a 16MHz crystal too.

**Per Hansson** · 10-06-2018, 09:29 AM

GM328R firmware attached containing latest SVN version 798 of Karl-Heinz firmware.
This time 16Mhz and 20Mhz builds are included, I have tested both.

@STJ

Is your old machine still sketchy ?

**stj** · 12-12-2018, 07:35 AM

worse,
drive is dead

i know why - the motor driver ic is shorted (ST smooth series) - i'm looking for a donor drive to get another chip.
