Re: ESR meter upgrades
yes, blue and other similar bob-barker based designs wont show leakage.

Re: ESR meter upgrades
pretty much all of the atmel based component testers - they all use the same softwareComment

Re: ESR meter upgrades
Hello
search (original) working HEX/EEP files and Fuse settings for the GM328 (AY-AT)
Transistor Tester (from Banggood) because my Atmega is broken.
The original seems to be protected against reading :-(
TX7014DH is on the Display,
thanks for a feedbackAttached Filesif you find these attachements useful please consider making a small donation to the site

Re: ESR meter upgrades
why original?
we have newer ones on this forum if you search - i know because i built and posted them!Comment

Re: ESR meter upgrades
which one is to be recommended that comes near to the original?
where can i download it?Comment

Re: ESR meter upgrades
https://yadi.sk/d/yW8xa5NJgUo5z
Inside folder: M328KIT+TFT
You can there find Firmware in original.
But also both Madires (M-Firmware) and Karl-Heinz Kübbeler (K-Firmware)
Note that the "original" firmware is of course the K-firmware with some changes by the Chinese, but not releasing the source code
If you prefer to build the firmware from source here is the SVN repo:
The latest K-firmware: https://www.mikrocontroller.net/svnb...oftware/trunk/
The latest M-firmware: https://www.mikrocontroller.net/svnb...ftware/Markus/
EDIT: You also cross-posted here and got a reply already from Madires:

Re: ESR meter upgrades
I found the firmware does not detect PNP germanium transistors. They get reported as a diode.
Another 328 tester (2x20 LCD) I built with Karl-Heinz Kübbeler firmware does work and tests the transistors OK.
This is on AY-AT/ST7735 20MHz xtal with SVN810 STJ.Comment

Re: ESR meter upgrades
maybe i should do a fresh build?

Re: ESR meter upgrades
Hello everyone,
I'm new to the forum and I managed to do my tester, but I have a problem with the version. The font is very small. Can anyone help with the .hex and .eep files ?Comment

Re: ESR meter upgrades
the my version is AY-AT ESR tester(SVN810) with 16Mhz quartzComment

Re: ESR meter upgrades
i dont have that model to test the different font options.Comment

Re: ESR meter upgrades
I made the model M328kit + 1.8''TFT Full Color LCD Display Module 128X160 Serial SPI ST7735S. I just had one. It works great with your software, but unfortunately the font is small.Attached Filesif you find these attachements useful please consider making a small donation to the site

Re: ESR meter upgrades
well you could try making your own.
you need the avrgcc compiler and associated tools.
i think those are in the arduino suit.
or use a Linux machineComment

Re: ESR meter upgrades
Thanks for your attention stj. I don't understand anything about programming. That's why I asked for help in the forum. For now I am freezing the project or I will seek help again! Thanks again!Comment

Re: ESR meter upgrades
yes,
the problem with changing fonts is that you need to take into account the shorter number of characters you can fit onscreen so it doesnt wrap or make a mess.Comment

Re: ESR meter upgrades
I won't be able to do it.
I stay like that. If anyone can help me , I will be very happy!Comment

Re: ESR meter upgrades
This is something you etched yourself lz4pa by the looks of it? Nice work!
What MCU did you use, Atmega328p?
Maybe I will have some time in the weekend to see if something can be improved.
I did not find a firmware for ST7735S display in the massive eevblog thread but I did not look very hard..."The one who says it cannot be done should never interrupt the one who is doing it."Comment

Re: ESR meter upgrades
Hello Per Hansson! Yes ,use atmega328p in this construction. I made the scheme of M328 kit + tft display based on st7735s. I guess it's all due to the difference in the resolution of the displays. Thanks in advance!Last edited by lz4pa; 01-14-2021, 02:03 AM.Comment

I read EBOOK of Testing Electronic Component and found that
"In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."
Is it really possible to test small ceramic disc capacitor with analogue... -
I have had with regular AA batteries that leak this meter is expensive new I already replaced the battery battery clips once and the same thing happened again and I am tried of so it is getting modified to accommodate lithium ion batteries that are the same size excluding the positive terminal and removing the battery clips I will have enough room for the BMS protection board
I going to put 3 lithium ion battery in parallel with the BMS protection board and a way to charge the battery externally and heat shrink the battery pack and use a JST connector so I easily remove the battery... -
Hi
I want to change the scale of an analog meter, to monitor the charge of an li-ion single cell, so the needle at the end would point 4.2 volts and the 0 on the meter would point 2.5 volts or so, i tried to add diodes or a zener in series with the meter but the changes of the ambient temperature also changes the voltage value on the meter
I wonder how i can accomplish this so the meter would be precise at any temperature ?

About a month ago we had a transformer jumper wire that burned in two different places between two transformers caused over $200 thousand dollars worth of damage to VFD drives at least 10 of them and a memory card and quite a few power supply as well
Now we have most of the equipment that got damaged back up and running except a feeder that has issues and we are waiting for some parts for
Now we also have another piece of equipment that was blowing fuses on the 110 volt controller switch circuit with the “E” stops and one switching power (24 volt) supply and a transformer... -
hi guys so i have this ps4 fat 1215 i believe ( the one with the ps4 pro/slim newer encoder ic ) so i replaced hdmi and 2 blown filters and still no pic so i replaced encoder and still no pic. i made sure port is solid even checked with a breakout hdmi and tested ground and data lines.. Filters are all good , though 2 of the newer ones are larger then the original ones i dont know if that matters ?
Made sure under the scope encoder pins all look solid went over with fine tip and solder again. Idk but this thing is stressing me out..
ps4 seems to boot fine blue light then solid...
