    I was very interested in your YouTube video repairing a Karcher window vac.

    Can you send me a link for the $1 charger please, as I can’t find anything like it on eBay.

    Best wishes,

    Really enjoyed your video on how to update the firmware on my Motorola DP3600(1). I’m having problem getting the code plug set up for this radio – any chance you could give me a bit of assistance or point me in the direction of someone who can?

    Many thanks

    Hi there;

    Great videos and work!

    With regards to “China HX-4S-F30A 30A li-ion 14.4V PCM problem and modification for high drain power tools”, found at, would you have a link to the 680nf capacitors that you were using as well as where positive/negative needs to be soldered into the board?

    Many thanks.

      Any non polarised will work – do not require positive / negative side (they can be soldered both ways). I bought them many years ago in assorted package so i don’t have link. Name to search “polyester 680nF” but since they are cheap recommend get whole assortment package. Thanks!

    if version >= :mojave
