    no, arduino is pre-programmed and the code is loaded by com-port.

    you need a usbasp programmer

      Ok, thanks...how about this one with a 10 to 6 pin adapter? Just looking to save a little DIY time, if possible...

        instead of spending $5,
        why not just spend half that!

              Hi I would like to try your latest firmware compiled for the T3/T4 tester version which I have and I added the rotary encoder.

              Thanks

                ok, try this.

                i need you to go into the menu and check the encoder works o.k. and in the right direction.
                then go into the contrast menu and find the best contrast value.

                finally, use a meter to check the battery voltage while it's on the lcd to see how close they are.

                  For some reason I was thinking there was only 32Kb of room for the program, am I way off
                  base?

                    no, 32k flash, and 1k eeprom.
                    why?

                      well, because, the size of the update files you've been putting up here started out at a bit below 32k in size, but kept getting progressively bigger, so it seems that either you've found a way to compress the files when loading them or I totally misunderstand what the update files are about.

                        hex files.
                        they are just over twice the size of the binary data because they contain address and checksum info.

                        also, each zip contains 2 versions and i now included the source files i modded.

                          Oh, ok, I hadn't tried unzipping one yet, I'll try that and see what I see - Thanks

                            i'm not sure why 3 people downloaded the T4 code without posting answers to my questions afterwards - that code is not tuned or complete!

                              say stj, I'm wanting to change from the atmega168 that's in my d-i-y esr meter kit to an atmega328 - from what reading I've done, it sounds like it should be doable once I have some kind of programming setup, what do you think? I was thinking of getting the 328 IC from digikey...

                                the 328p is a direct swap.
                                they are probably cheaper on ebay though.

                                  Well, I tried ebay, wasted 2hrs. trying to find a seller who'd ship to a po box - then, went through the 'checkout as a guest' all the way past entering my debit card # and they wanted a different debit or cc #. It's worked fine on 2 other occasions, and I know how much my balance is, so wonder wtf...

                                        then you need a 16MHz crystal and a pair of 22pF caps that can fit between the crystal pins and that center hole.

                                          Ok, thanks, I think I saw a suitable crystal at digikey for less than a dollar the other day.

                                          Now it's time to do a youtube crash course on avr programming now, I've watched a few from newbiehack.com and think Patrick Hood-Daniels does a pretty good job of explaining things.

                                          BTW, sometimes I behave like such a clown, yesterday when I was shopping on ebay I forgot to enable cookies - I still can't buy from ebay today, but that may now be because I made so many tries wo/ cookies yesterday, what do you think?

                                            Is it possible to test small ceramic disc capacitor with analogue meter?
                                            by chth96
                                            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...

                                            Modification of a Fluke multi meter that uses three AA batteries to use a 14500 lithium ion battery
                                            by sam_sam_sam
                                            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
                                            by sam_sam_sam
                                            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...
