    Re: ESR meter upgrades

    Contrast is fine.

    Fixed by remark out: CFLAGS += -DSTRIP_GRID_BOARD

      Re: ESR meter upgrades

      well that file is almost exactly like mine,
      you have contrast at 48, i found 50 is dead-center

      your H offset is 0
      CFLAGS += -DLCD_ST7565_H_OFFSET=0
      i have to use 2 or some problem happened i cant remember.

      and you have
      CFLAGS += -DLCD_SPI_OPEN_COL

      i have that hashed out.
      i cant remember why, i need to mess with that later.

      anyway - now you got that far - if your happy with the makefile i can try to make you a firmware with my *other* changes

      those are mostly saving space, but the frequency generator is different and the contrast menu is gone.(to save space)

        yes, I am now going to see if those parts upgrade can be salvage from some stuff I have around here.

            Well the kit has just arrived the bad news is the pcb has none of the parts identified on it bacically its marked r1 r2 c1 c2 etc no instructions either in the package and the seller hasnt got any either i will try to upload a picture later but without knowing what value resitor/capacitor etc goes where im a bit stuck.

                sure is heres the pictures of course some of it its easy to figure out but resitors value location im stuck on also theres three diffrent transistors types so stuck on locations for those too.

                    Re: ESR meter upgrades

                    cheers stj someone else also posted this new manual for me on eevblog im just having a read of it now and also going too measure the resistors in the kit and see what matches up etc.

                    Im just measuring all the resistor values in the kit and also seeing what the four transistor part numbers are the rest i have already figured out.

                    its a 8 mhz crystal
                    transistors are 2x c945 p331 1x 4673 4c gf 2 1x ws tl431 928
                    resistors x6 10k x2 110 ohm x2 27k x3 470k x1 470 ohm 1x 33k x3 680 ohm x1 100k x1 5.6k x2 3.3k x1 2.2 there is also x1 brown looking type resistor but it only has 1 black band dead centre of it but there are 23 resistors in this kit plus the odd brown one but only 21 fitted resistors in the kit.

                    Now the main issue what resistor transistor goes where.

                      '1 brown looking type resistor but it only has 1 black band dead centre of i' That sounds like '0' Ohm jumper.

                        Re: ESR meter upgrades

                        brown resistor with a black band is a 0-ohm jumper

                          thanks budm your spot on thats exactly it, not sure why its in this kit as i cant see it on any pictures of this tester.

                            it's nicer than a jump wire when you have to cross some tracks or have a connection you may need to open for tests.

                              thanks guys although i cant see that 0 ohm used on this tester in all the pictures online Whats your thoughts guys regarding selling these kits but no build instructions? hows the average hobbiest supposed to know which part goes where? theres nothing in the add to say about instructions either way im struggling to find information about it im using this site and eeblog and even those guys dont seem to know as yet what goes where etc

                                i would be tempted to ask for a refund because it cant be built without a reference sheet - that will make the bastards jump.

                                  Too be honest i just have if i can get a refund i will buy a pre built one the problem is who pays for shipping back too china? as thats not going too be cheap.

                                    it's unlikely they will ask for it.
                                    they may post a big foto of a built one if they have it - because it effects all the customers.

                                      I bought one too but I'm still waiting for it, so I'm very thankful for your work on this vinceroger
