    nice, just a heads up all your links are invalid.

  2. Avataaar/Circle Created with python_avatars Roy Tellason says:

    Those connectors with the plastic around them are referred to as "shrouded", and are handy when you want to make sure that the connector on the ribbon cable goes on in only one orientation…

    Got the same 10x 40/dual pin headers from Hong Kong seller for a buck, so I ordered single, dual, and bent dual batches. I'm set for life! LOL
    Julian, you can't imagine how much you've cost me because of my watching all your Postbag vids. Luckily, between Hong Kong, China mainland, Thailand, Vietnam, and Malaysia, all these things go for a buck or less. Those same little items sell on shelves here in Oregon, US for $12.99, complete with the Made in China tag and identical packaging. =:0

    to crimp (mechanical connection) such terminals is much more secure than to solder, solder can melt 🙁

    Why is Julian building screens in front of his beautiful lead acid batteries?

  6. Avataaar/Circle Created with python_avatars himselfe says:

    A plastic tax so we can move to more environmentally damaging packaging like cardboard and paper? Let's not!

    Bit surprised you favour ebay so much over Aliexpress – those 2×40 headers for example are cheaper on there than the $3.68 you paid on ebay
    :

    item: "32858697985" 10PCS 2X40 Pin 2.54mm Male Header (choice of Red/White/Yellow/Blue/Green)

    $1.30/lot + $0.62 delivery 1x is $1.92 total (or in GBP, £1.09 + 52p delivery, £1.61 total on today's exchange rates)

    item "32853351049" 5PCS 2X40 Pin 2.54mm Male Header (Black) $0.80/lot + $0.62 delivery, 2x is $2.22 total (or in GBP, £0.67 + 52p delivery, 2 sets, 10pcs would be £1.86 total on today's exchange rates)

    lose the interrupting ads, please

  9. Avataaar/Circle Created with python_avatars MrBrymstond says:

    I mentioned a BMS before that would take the excess voltage from one cell and add it to another in the series that's lacking. Someone told me it couldn't be done. If that's true, we might as well hang it up.

    I had to remember you to look you up I never see videos anymore ALTHOUGH I AM SUBSCRIBED.keep it up thanks for the videos I will catch up on them lol

  11. Avataaar/Circle Created with python_avatars Anvilshock says:

    A plastic tax, as well as a plastic loicense, plastic-loicense "enforcers" (sent round by Capita, of course), plastic-usage-monitoring CCTV … you know, the usual.

  12. Avataaar/Circle Created with python_avatars Jens Schröder says:

    from the power supply to each board is a GND. in the ribbon cable are many GND. hmmm, do not make to many ground loops! Just try it. A GND star point is better for audio. or add later some 10R resiistors in the GND wires? Just triy it!
