Merry Christmas and a happy new year 👍🏼

[@Electronzap]

Thanks, you too!

[@andymouse]

Thats an interesting chip, I will keep it in mind for switching a bit of current (500ma) Merry Christmas and a great New Year !.....cheers.

[@Electronzap]

Yeah, 500mA is the maximum according to the datasheet. Merry Christmas and New Year to you too!

Thank You

Thanks for watching!

coincidentally I opened my 'christmas bells' last night as i had lost the adapter and needed to 100% know polarity, it has the same IC to drive the little solenoids that ring the bells to play tunes, it has 9 bells.......guess its wired odd, now I need to know lol

That's interesting. Thanks for watching!
