Forum Rules *ALL NEW MEMBERS, PLEASE READ!! UPDATED!!*

First and foremost, Welcome to the Badcaps Capacitor Search Engine & Forums!

New members that have activated their accounts have limited access to certain features of the site until established. Members with zero posts have no access to the private messaging system. Also, members with zero posts may not edit certain profile attributes, such as signatures. New members also may not create new threads. However, new members with zero posts have full access to all technical information contained on this forum, and that also includes attachments (images and files that other members have uploaded), and new members that have activated their accounts are free to post replies to existing threads. If you wish to create a new thread, the fix is simple! All you need is ONE post to be able to have full unrestricted access, and that can be simply posting an introduction of yourself or say hello in THIS THREAD. This may seem a little strange, but it helps keep spam and abuse curved. Please note, that it may take up to one hour from your first post for the limits to be removed. If you make a post and don't immediately see the restrictions gone, be patient. The promotion system updates every hour.

Please complete your profile after making your first post, with your name, locale, and other info. It's nice to know members on a first name basis, and know where they're from. Makes for a much friendlier environment!

Posting rules for this forum will be STRICTLY enforced by myself as the owner/administrator, and my moderator crew.

Badcaps.net IS A BUSINESS!!! If you are a servicer, service center, or vendor of any kind in the computer/capacitor industry, you are NOT permitted to advertise, link, promote, or plug your business on this forum in ANY way! NO EXCEPTIONS!! This includes asking for "donations" in exchange for BIOS passwords or tech advice for anything! If I see you doing that, your post will be edited or deleted, and you warned. If it happens again, you will be banned. The only exceptions are the references to the companies quoted in the FAQ which the administration have added for the convenience of those around the world who have difficulty to source caps for their repair.

This also includes using this forum's private message system to solicit business. Members, if you receive a PM from anyone offering repair services or components, please alert me immediately! Myself or any of my moderators, will never private message a user soliciting business, for Badcaps.net, or any other servicer/vendor. If you PM me about repairing your device, I will reply and take care of you, however, I will not message you first.

------------------------------------

Posting rules:

This forum was created to be a technical support forum primarily for the do-it-yourselfers who choose to repair their own boards. Any and all technical questions are welcome!

1) Please use the SEARCH feature!! Your question may have been answered in another thread! Please search first and see if it has!

2) When posting a technical question, be as detailed as possible in your thread. The more information we have about your specific problem, the better we can answer your question.

3) Please use COMPLETE sentences, punctuation, and grammar! Nobody is perfect, hence, a spelling error on occasion is no biggie. However, posts/threads that are unreadable will be deleted. This includes any and all forms of 'ebonics', leet, chatroom jargon, and 'text message' shorthand and slang. This forum is not a chatroom/text message, please use full words and complete sentences.

4) Keep discussion on topic!! DO NOT HIJACK THREADS! It's easy to do (I've done it myself a few times...) Lets try to keep it down to a minimal!! If you have something really off topic, that's what the lounge is for!

5) Keep things civil! There will be no tolerance for flaming, bashing, hateful remarks, racial remarks, adult material of ANY kind, and so on.

6) THE LOUNGE RULES! The lounge is a place for off topic chit-chat! If you post something that might be considered questionable or something you don't want kids to see, or something you can't view at work/school, etc, please label that thread *NWS* or NOT WORK SAFE in the thread title as a warning. The Lounge is NOT moderated, anything is welcome... Feel free to post rants, jokes, cars, hot women (remember the NWS warning in the title), or just about anything within reason. It's an open forum! Please refrain from participating in political topics if you have thin skin, they can get heated sometimes!! Remember that we have members here from all over the world, with many different views and cultures. Political debates can turn really ugly, and really fast, and if they degrade to personal attacks and useless banter/bashing, moderator action will ensue. I want this forum to be a safe haven for technical discussions from all walks of life, so lets keep off topic discussions civil and friendly.

7) Spamming and spammers will NOT be tolerated or accepted in any way, shape, or form! Spam bots are instantly and permanently banned, and their threads deleted! The mod crew is really quick to zap spammers, we typically pop them before they even get to post. This also includes regular members as well. be courteous and not post spam. This includes links to off-site information that's not relevant to the thread at hand. Do not plug other websites, forums, or businesses in your signatures. You may do so in a thread if the off-site link you're posting is relevant to the topic, but otherwise, don't do it. If you see a thread which clearly a spam bot posting that we have not removed yet, DO NOT click any links in it!! Simply click the 'report bad post' button, and it'll be taken care of, usually within minutes.

8) Account removals & closures: Since no personal information is given in the creation of your Badcaps.net Forum account, requests to remove and/or delete accounts will be declined. Any requests for removal of threads & posts you created will also be declined. The reason is the missing posts can/will leave threads incomplete and fragmented. For the threads to be of help to others later on, information can't and won't be missing. However, if you inadvertently posted personal identifiable information in a post (such as an email address, real name, or phone number), please contact a staff member. In those cases, the post may be edited or removed, at the staff members discretion.

That's about it for the rules, the setup here is pretty loose. However, if you're caught violating any of the rules above, here's what will happen:

First offense: Warning by me or a moderator
Second offense: Banning for 1 day
Third offense: Banning for 3 days
Fourth offense: Banned permanently.

If you do something really dumb, or are just a troll, I will skip the warning and the temporary banning, and ban you permanently!

The rules are pretty cut and dry... However, if you have any questions about this policy, feel free to contact me.

    Re: ESR meter upgrades

    Do you mean the issues posted by madires here?
    http://www.eevblog.com/forum/testgea...-project/2900/

    Because I do have a 20Mhz crystal too, didn't make that clear I see now

      Re: ESR meter upgrades

      no, the firmware i posted is not from madires - it's from karl heinze.
      completely different code.

        Re: ESR meter upgrades

        Ok, I thought you had compiled madires firmware too, guess my memory played me a trick
        Gives me a good excuse to try it myself, might wait for the next release though as he mentioned a few caveats in the current build with the 20Mhz option...

          Re: ESR meter upgrades

          *if* you do that, put the crystal in a socket - or you will be stuck with madires firmware.

            GM328x ESR tester (SVN684) - small fonts.zip
            Is there an easy way to change the operation of the rotary encoder, so that downwards movement through the menu corresponds with clockwise rotation? (rather than anti-clockwise)

            Comment


              Re: ESR meter upgrades

              set a flag in the makefile and rebuild the source.
              # the option CHANGE_ROTARY_DIRECTION changes the rotary direction by swap of switches
              CFLAGS += -DCHANGE_ROTARY_DIRECTION

                Re: ESR meter upgrades

                Ok, i see that that code is already the makefile.
                How does one set this flag in the makefile?
                Do i need to download a compiler?
                Can it be done with windows XP and Codeblocks?

                Comment


                  Re: ESR meter upgrades

                  edit the makefile with any text editor, then compile it.
                  does codeblocks build AVR ?

                  Comment


                    Re: ESR meter upgrades

                    What exactly needs to be added/changed in the makefile?
                    i really have no programming compiling skills except extremely basic stuff, that i've mostly forgotten.
                    Definitely don't know what a flag is.
                    Will AVRdude rebuild the source, and which one is the source file? Is it transistortester.h ?

                        Thankyou very much
                        Works nicely (did you just comment out the flag?)
                        Noticed that ESR was not right after 1st calibration - but it came good after the 2nd calibration.

                            Please find attached the most recent compiled version of the mega328_st7565_kit - Standard 8Mhz, English, v1.12k rev 700

                            I've had some fun this week learning how to use an Arduino to flash some blank chips, patience and more coffee got me there in the end I've tested various components, all seems fine.

                                This is better because you can put in whatever frequency you want.
                                But why's the text a mirror image, and also upside-down? (at least on this meter)
                                so i went to https://n2github/transistortester/tr...mega328_st7565 and programmed it with that.
                                Now it's looks good, except that there is only a third of the first character on each line, and it's only upside down and not mirror-imaged

                                  You're having some problems? I didn't see anything flipped upside down text on mine, is that somewhere in the menu? I haven't looked at the freq counter on mine. I might potentially need to use a different tool chain as I've seen mentioned that the one shipped with winavr can cause troubles, this might be related!

                                  Ignore the rev 700 i posted, I got the revision number wrong!

                                    you have a GM328 not an st7565_kit.
                                    different hardware needs different firmware.

                                        Yeah, the penny dropped just dropped a few minutes ago.
                                        The GM328 on that website works good but no rotary encoder/option. And i see that that's what you've enabled - but the frequency option has being restricted.
                                        Is it easy enough to recomple it, so that any frequency can be inputted?

                                          the different frequency generator is intentional, the changed code is in my zips.
                                          the frequency code that you can allegedly input any frequency is very difficult to use.

                                          @jondoe - use the makefiles from my zip - the regular one is pretty wrong.
                                          infact most of the makefiles on the SVN are only just working and need to be finetuned.
