ESR meter upgrades

Re: ESR meter upgrades

well i'm confused.

there is only one button input, and i assume it works because you can power the unit on.
maybe that assumption is a mistake - let me check the schems.

There is only S1 start button on this device.apart from the addition of the encoder.
could it be the 16mhz crystal causing the problem of selection.?
I have checked the voltage on the start button which shows 9 volts collapsing to .7 volt on press on then returning to 2.7v on the live side powering the display, returning to .7volt every press, voltage on PD 7 drops from +5 volt to .7 and returns to 5+ on release of the button.The encoders center pin is to chassis
each leg is supplied from 5+ rail via 10k resistor and PD1 & PD3 is fed via 1k resistors. The firmware I am using is your TEST 16mhz stripboard. which seems to tick all of the boxes except select from the menu.

Re: ESR meter upgrades

that firmware is totally unconfigured.
i'll post something better later.

Re: ESR meter upgrades

some quick builds:
GM328 and AY-AT for 16MHz
both using compact font with more menu lines.

and a T4(strip-grid) 16MHz testbuild for TEDDIBEAR.

Re: ESR meter upgrades

stj you know that 2016 tester you helped me build etc is there a case available for them? ive had a quick look on aliexpress etc and cant seem too find one.

Re: ESR meter upgrades

no idea.
there are probably 3d printed ones if you ask over at eevblog

Re: ESR meter upgrades

Thanks i will ask in the thread and see what they suggest i might also update to a AY AT at tester as there are cases/firmware already available.

Re: ESR meter upgrades

can one of the people who downloaded the AY-AT code please post a screenshot of the menu screen.
i'm ajusting the number of lines to fill the screen.

Re: ESR meter upgrades

Here some screenshots of the "AY-AT" with SVN749 (STJ V2) firmware.

Hi stj
thank you for your update I am afraid I am still unable to select from menu
here are the results. + when a test is made it stays on the screen for a split second too quick to read

I think the problems with the menu side were the same, having said that I can not read Russian but the menu did not seem to change when a selected item was pressed. Your first T4 worked perfectly as did the second T4 as far as diagnosis were required the second one had smaller fonts and very fast, the problem seems to be selection from the menu pressing button.

Re: ESR meter upgrades

Hi STJ, I like your avatar, I've been in facebook jail 5 times already. Can you please compile another lipo version of the AY-AT like you did for me before on post 855 but with the modifications that fill up the display? the 3.2 volt cutoff version worked best, the 3.6 cutoff version gave me a low battery warning when the lipo was at 3.9. BTW the rechargeable mod I made in post 873 works great.

Re: ESR meter upgrades

the build box is out of action for a couple of days - i'l take a look after.

Re: ESR meter upgrades

Do you have a paypal account? I would like to give you something for your buildbox fund. You've been very helpful. private message me your account address.

Re: ESR meter upgrades

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

Re: ESR meter upgrades

no, i need to get back to that.

Re: ESR meter upgrades

Hopfully this isn't too off topic. Is there a concensus on a good prebuilt variant of these component testers? I'm particularly interested in using one for manual ESR testing.

Re: ESR meter upgrades

Thanks for the recommendation. I like that it has a case and probe ports. But I'm wondering if it has menu access like the GM325. Does this allow for manual settings for component testing? I mean can it be set specifically for testing ESR, without the firware trying to guess what the component type is? Also, I have read that it does have a flashable firmware. Can you confirm this?
