After a lot of faffing I managed to get the MQ1 working standalone…I snipped the barrell off a 15V 1A psu and wired that into a regulator circuit that I bought as a kit online for pence…out of that the + – feeding into the relative molex rails on the back of the MQ1
It is way quieter and is really cool piece of kit.
Now to work on some kind of chassis/housing
