    Continuity Tester for Codger...

    If you don't wish to do surgery on your DMM's, maybe as already suggested above, use an electret mike? I first considered an inductive pickup, but as most DMM's use Piezo transducers, threw that idea out. Running with the electret idea, here are some graphics examples. The basic idea is to...

    Is Kester 44 60/40 rosen core solder correct for general work?

    I think this is also called 'surgical spirits' sold in pharmacies, used for things such as cleaning skin, elastoplast adhesive, etc. Works well for scrubbing soldered boards clean.

    DC power over coax

    Hello Pine. What connector does your video remote video camera use? USB, AV with separate DC supply? DIN socket? If you can supply a clear photo of the business end of the connector, then a solution will be easier to work out. Regards, Clive. Afterthought: By 'remote', do you mean 'cabled' as in...

    Circular?

    Hi KE. Although this thread has grown a beard already, did you come right with the circular board? Playing around with Diptrace, the easiest method I found is: [1] create a standard square / rectangular board using 'board outline' icon. [2] right-click the outline then from the 'pop-up' menu...

    PCB Order Mirrored?

    The standard (with our local PCB manufacturer's instruction PDF file) which accompanies the order form, states that ALL layers must appear in GERBER format, viewed TOP view, so the bottom layer will be seen as if viewed from the bottom. The CNC ( or other) software at their end will arrange it...

    Speeding up and re-using Ferric Chloride etchant tips:

    As a long term ferric chloride user, I came across this interesting 'Instructables' article, so decided to try it out. It definitely makes a improvement to the etching time, with the downside being that the user is working with dangerous corrosive acid (Muriatic, aka Hydrochloric acid), as in...

    Book Reviews

    No doubt some book titles have already been mentioned during the time-frame of creating my Excel>PDF list. As the list is quite long, and contains several columns of data, it was decided to use the spreadsheet-to-PDF format rather than miles of text rows. Hopefully the PDF is displayable on the...

    Controversial schematic symbol

    I have a book of full schematics and circuit-snippets where there should be a polarized capacitor, instead the (submitter?) of the circuit has failed to indicate this. While not wanting to slander or defame the author or publishers, this smacks of laziness in drawing and post-editing. The two...

    Faulty usb-port

    The 4 square pads are for the metal frame tabs. Solder-pad pins 2, 3, 5, and 7 look ripped in photo, but that could just be solder not reflecting light. Maybe you could try this: Line up USB socket until all 10 pins align perfectly. 2 wooden clothes pegs or similar could temporarily clamp the...

    Frankenstein's Components.

    Provided that you discharge the cap correctly, with a discharging resistor tool, NOT a screwdriver, using correct procedure, then once discharged, short out the terminals, the cap will be safe to handle. I agree with salvaged parts from an old micro being a mine of useful components - Rare-earth...
