I bought this from AliExpress purely to marvel at the idea of using such a low power heater for heating an aquarium. It would have to be pretty small and have a low heating requirement.

The device does potentially have other uses though, like maintaining fermentation temperature in an insulated container. The control module seems quite useful, as it’s got a MOSFET rated for 2A and circuitry that could make it easy to adapt to a higher voltage like 12V. (Just change the incoming supply electrolytic capacitor.)

The circuitry was more complex than expected. Especially the voltage divider used for monitoring the 10K thermistor.

So if you need a low power controlled heater that can run on a low voltage supply, this might fit the bill.

Here’s the listing I bought it from, but there will be others too:-

I recommend using PayPal as a security layer with AliX, as they keep your card data (including the security number) on record. And if they have a data breach they are unlikely to confess to it.

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- https://www.bigclive.com/coffee.htm
This also keeps the channel independent of YouTube’s algorithm quirks, allowing it to be a bit more dangerous and naughty.
