Inside a Marq LED smoke machine from CPC. (With schematic.)

More or less the same as a shady eBay unit, but with all the extra safety features required for compliance with local safety standards. This unit seems quite good for the lower end market it's aimed at.

This version came from CPC in the UK, but I'd guess it's available from other sources around the world. It looks like one of the many branded versions of generic products, where they have been made to a specification suited to the target market.

Here are direct links to the units at CPC.

There do seem to be other sellers including on eBay, but there also appear to be similar but completely non compliant versions on eBay. An XLR (microphone) remote connector is a red flag. It's often being used at full mains voltage and poses a massive shock risk if cables get mixed up and a microphone gets plugged in.

If the smoke switch is left on the unit alternates between blowing out fog for about 15 seconds and then reheating for 30 seconds.

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
