    Re: ESR meter upgrades

    you solder the 6pin / 10pin header to some pins under the socket and hook the usb programmer to it.

    then you open a shell / console with avrdude installed.

    and type or cut-n-paste this.
    avrdude -c USBasp -P usb -p m328p -U flash:w:TransistorTester.hex \-U eeprom:w:TransistorTester.eep \-U lfuse:w:0xf7:m \-U hfuse:w:0xd9:m \-U efuse:w:0xfc:m
    that's all.

      I must have been editing my last while you were replying.
      I sure appreciate your help, I'll have to do some reading up on avrdude.

        can you ask the sellers for a copy of the makefile.
        they are obliged to share it under the open-source license anyway.

        i want to compare it to the one i just put together.

          I'm afraid I can't - the last time I sent an email trying to get help from them they sent it back as undeliverable, before that they (she? I suspect it's a one person operation) was non-responsive to my questions and there were no links listed for either troubleshooting,
          faqs or software for it. At the end of calibration it says it's v 1.12. Here's a link if you want to have a look around:

              No kidding? Where they at? (just kidding) Any of the titles sound even vaguely related to electronics-diy?

                  Re: ESR meter upgrades

                  i now have a test-build for e-diy, let me know when you have a cpu & crystal
                  you may want to replace the regulator with a MCP1702-5002E/TO aswell

                    Cool! Where did you find that at? Is it much, or any, different from what's initially running on the newer ones (like you've got)?

                    Anyway, thanks, it'll probably be a few weeks before I'm set to update this thing

                      i didnt find it, i made notes from the crappy schematic and then adapted the makefile to get close to it.

                      16x2 lcd
                      no contrast control
                      no power control
                      no crystal
                      strip-grid pinout
                      no v-ref
                      bat monitor is standard.

                        Most ingenious; however, I was hoping you'd found your way into the inner realms of e-diy. Oh well, probably not missing much...

                        Actually, there is a contrast pot, it's called p1 and is 10k

                          i know that, the note was refering to software control.

                            Oops, beg your problem...

                            I'm curious, does that (contrast info) go in the file and it may be commented out, or not, depending on the kind of LCD it has? just wondering how different the software is between the two versions of meter.

                              if you downloaded any of those zip's - look at the included makefile for the options.

                                I think I have a mental block or something, it all looks rather daunting, what with three different kinds of files that all seem somehow to be related to the actual program, if it wasn't for utube I don't think I'd have any chance at all of ever getting any thing programmed, at least not without going back to school.

                                That being said, I got an Arduino Uno so I'm wondering what you think of this link:

                                http://www.instructables.com/id/AVR-...-gcc/?ALLSTEPS

                                I figure it would be handy to have the means to make some kind of custom controller set up for a few motion sensors and cameras once I'm thru messing with the
                                esr meter.

                                  if you want to learn to program wih an arduino,
                                  first rule - dont play around, take it serious.

                                  learn some C and go here:
                                  http://www.codeblocks.org/

                                  when you run out of power (your arduino that is!), get one of these 32bit monsters:
                                  http://www.st.com/web/catalog/tools/...N1847/PF262063
                                  they only cost $10 !!!

                                    Let me guess, the more I play around the more costly it'll be? Anyway, thanks for the links,
                                    seems odd that a 32 bit controller can be so cheap, it doesn't look like they're from China.

                                      no, $10 gets you a 32bit board with built in usb programmer / debugging port.
                                      all software is free.

                                      it's simple, ST is making the boards to sell at cost to get designers to design stuff with their chips and not atmel or TI's
                                      $17 get's one much more powerfull with 144pins and onboard ethernet!!!
                                      not that most people would use either - so go with a $10 type.

                                          I'm very keen to upgrade to your T4 code and provide answer. Can it work on my "LCR-T4 Graphical Multi-Function Tester"?

                                          I also ordered a 40cents rotary encoder:
