  2. Where we are now: The site is back up and running! The character set encoding issue has been fixed so old posts should now look ok. I am currently working on themes/skins etc and I will be deleting the temporary green skin very soon as it has many issues. I will do a very quick variation on the stock blue skin first just to get a light-grey background and san-serif font, and I will set this as default. Later this week I will hopefully add a professional third-party skin in pfm colours (life is way too short to do this crap myself, and I've found one I really like than needs next to no tweaking). We are getting there slowly...

  3. May I please request people check and update their email address if it is out if date. I ask as I’m getting countless bounce errors as the server fails to send notifications through etc. I’ll eventually figure out how to send these to a black hole somewhere, but it makes sense to address it at source as quite a few folk are obviously not getting the thread and conversations notifications they have set in their preferences.

  4. Things you need to know about the new ‘Conversations’ PM system:

    a) DO NOT REPLY TO THE NOTIFICATION EMAIL! I get them, not the intended recipient. I get a lot of them and I do not want them! It is just a notification, log into the site and reply from there.

    b) To delete old conversations use the ‘Leave conversation’ option. This is just delete by another name.

How do I repair a lifted tracks on a PCB?

    If you stick them down with cyanacrolate (superglue) you get a nice bond but the white residue will need to be cleaned up afterwards, other than that, it's a case of carefully flattening down/straightening out the track very carefully using the bent end of an engineers scriber and depositing the smallest amount of glue you can physically see on the track and holding down and flattening out as you go.

    After it is set, remove any residue and scrape off some of the insulator, enough to get some solder on and either make a solder bridge (assuming the tracks are butted up against one another) or salvage some copper strip off an old pcb for a bridge or a wire bridge.

    If the track in question is in the powerline or signal no probs, if in some kind of feedback loop, you might want to keep it as minimal and neat as possible, feedback is funny like that.

    Thanks. Thats the ticket. ISTR using similar stuff but it came as pre-shaped tracks in the days before I etched boards... Its just the 0V of a 24V rail but the section ends with a connector pin hole which makes repair with wire a tad tricky...

    Cat 5 solid core, insulation removed, glued down?

    I would be cautious of using glue; when I left school I was a technician in a factory assembling JVC videos. Any last minute revisions (electronic bug fixes!) would be fitted and glued down using JVC supplied glue on the assembly line.

    Fast forward 5 years and I used to remove the same glue from a video cct revision when working in a repair shop; glue introduced resistance/capacitance over a period of time and created some nice hum bars....

    I'd just expose additional copper track and use soldered wire as a bridge and then leave clean.

    Fox, I have some of that sticky copper track if you want me to post you some.

    please do I need maybe oh... 10mm for the missing track and maybe 5mm for the lifted one. LOL

    I'll PM you
