    Default Locating a 'Circuit Pen'

    I'm in a bit of an interesting predicament regarding repairing the keyboard in a really old laptop, and some of the traces in the plastic sheets have some breaks in them. Common practice in something so small, I think, is to repair the traces using conductive ink, basically, but I'm having a really hard time finding a conductive pen around town. I don't really want to order one off the internet because I'm impatient - does anyone know where I might find one in Calgary?

    I know these go by a bunch of different names depending on the brand - I'm not picky, as long as it's a reasonably fine tip. These used to be really popular in oldschool Overclocking (repairing laser cut traces in the old AMD Athlons and Durons comes to mind) so I was hoping maybe someone would know.

    You can also use the rear window defroster grid repair kits. Not as elegant of a solution as the pen but likely easier to find. I used one to unlock my Athlon back in the day.

    Active is way overpriced but has better hours than MRO. If you're in the south, hit up:

    I used a pencil to unlock my Athlons

    You may be able to just draw a line between the break with a pencil if you can get some graphite to stay down. I used to do that to unlock some processors wayyy back.
