    Re: ESR meter upgrades

    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)

        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.

                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.

                  btw, i ordered one of these in the sale.
                  https://www.aliexpress.com/item/New-...814430302.html

                  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.

                      upgrade to a 16MHz crystal too.

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

                            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.

                              just did a fresh build
                              not tested yet.


                              GM328 - every option on, low bat @7.2v

                              AY-AT no BJT / PUT testing - i tried real hard but there is simply not enough flash.

                                  i did, nothing has been added since.

                                  the way i see it, there is no point building one if it costs over twice as much in parts as buying one from china and upgrading the crystal.

                                  i will buy a new one when i see one with an atmega664 or 1284 and a colour display that i like.
                                  i wont buy or recomend any atmega328 based stuff now, they just dont have enough memory for all the features.

                                    Anyone have a PUT or UJT to play with on these testers?
                                    SCS?

                                    I suppose DIACs are more available but testing such on these things are going to be tough?

                                      maybe a diac works - i dont have one to try.
                                      not even seen one for decades.

                                      in theory it may be detected as 2 diodes.

                                        I have a few UJTs in my junk pile, but not PUTs or SCSs. Yeah probably should show up as two diodes or something to that extent. (Incidentally, how could SCS be tested? has more than 3 pins...)

                                        DIACs I have a couple and they're still being made/used, but I don't think they could be properly tested. They might detect as a funky high ohm resistor or something? Not sure. I don't have one of these testers to try.

                                          a diac would probably show as a pair of zeners.
                                          i think i may have one on an old switching psu for halogen lamps - maybe i will be able to test that theory.

                                            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...

                                            Changing the scale of an analog meter
                                            by jorpec
                                            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 ?

                                            How an incandescent light and a ESR meter ** friend**have a machine blowing fuses

                                            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...

                                            ps4 1215 model Changed port and encoder still no video?

                                            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...
