    Component Identification

    Similar to QDIP, the DIP-##H IC package is also 2 sets of DIP, but the 2 grounded heat-sink solder tabs/pins drop straight down rather than curve out in the 'Q' tail. The 2.5W stereo audio power amp TA8827PL is a DIP-12H example. The 'H' horizontal bar is the common ground (heat-sink) on both...

    Buzzing sound in speakers

    K.R, as you mention buzzing, I guess it's near radiating source such as fluorescent lights, TV screen, computer, etc. In that case, then as AG suggested in #2, keep leads short, screened. In addition, you should mount the amp in a grounded metal enclosure. Are you testing with one input source...

    Thanks, Bob. Well I guess it's time to upgrade it anyway, about 5-6 years old.

    Optical mouse interrupts being ratty?

    My computer at home has been randomly opening windows, selecting icons or task-bar items lately, often when I move the Genius 3-button optical mouse across the screen, without touching buttons. I also found at times it will do this even when not moving or touching the mouse. When this happens...

    plastics electronics crack

    Q-Bond is a superglue liquid & re-enforcing powder (aluminium or plastic) kit to mix as required. Car spares and hardware shops may keep it. Slowly build up a rock-hard shell around the posts by alternating superglue and powder. Epoxy putty (the one that you mix) will also work, as long as a...

    Which BB>XHTML parser is used & errors in BB help

    Hi. Parser? Is the new Electronics Point / EETech still using Xenoforo, or phpBB? If either, which version? Can I download parser software or the html parser / tester package?, .. as phpBB.com provides a downloadable app from their site called SCEdit. The user opens Example.HTML then types in...

    27Mhz FM Transmitter and receiver circuit.

    Available as a complete parts kit, RSE used to sell a 27MHz walkie-talkie, with components, PCB schematic and instructions. This had its antenna output attenuated, and warning re not to extend supplied antenna length. Forgot what the max output was - suppose <100mW.

    Directive RF through 2ft concrete to pickup?

    Thanks for the replies. This is actually for a friend in distress, as their shiny black Merc also gets a white splatter-paint job when parked under their house. The plumber told them it will cost about R8000-R10000 to perform a leak test with their fancy equipment. I offered to help out with...

    Directive RF through 2ft concrete to pickup?

    The (cold) water drips through a crack in the plinth underside, yellowing and peeling the paint. The idea I had is to use a "signal proximity" method rather than metal detector. === I have a small home-made FM BCB mike / transmitter as well, so plan to also try this, fed by modulated audio...

    Directive RF through 2ft concrete to pickup?

    Hello. Want to follow and trace a paint-peeling leak mark in basement garage to the floor above this plinth, which is a passage near the bathroom. I suspect a galvanized steel (or copper) pipe has rotted from old age, and is buried somewhere under the floor. I want to build a coil or other...

    IR photography and patches (read for elaboration)

    I once watched a you tube tutorial on removing a mobile phone's filter (can't remember now if it was IR or UV). A point the poster made was that once removed, the phone was almost useless for visible-light photography, as all pics were heavily fogged.

    MOV blown on NiMH 4xAA cell charger - cause?

    Or faulty IC or load-shedding spikes and surges. The socket is on a 5-way floor-standing horizontal multi-plug, so it could have been an earthquake..

    MOV blown on NiMH 4xAA cell charger - cause?

    Thank you for that info.. As you may have guessed by now, I know zilch about MOV's. .. Just realized.. the MOV is directly across the supply (after the fuse), so it wouldn't be low R as I thought. (Note to self - look up / Google "MOV"). :confused::D ADD: I now think I found the source of the...
