I adore a intelligent, bespoke answer. The extra area of interest, the higher. What will get me curious is considering what different methods I might use that answer, designed to unravel one drawback, to unravel a wholly completely different drawback that the creator won’t have even considered! Possibly all these causes are why the Burn Child Burn PCB caught my consideration.

The board is a nichrome cutter module, normally utilized in aeronautic initiatives, like high-altitude balloons and mannequin plane. The cutter permits you to minimize by issues like rubber bands and fishing strains to set off a launch system, like a parachute or drop sensor.

With a mounting hook to your line, and a mounting gap on the PCB to connect the module to your challenge, set up is easy. The burner is powered by a single-cell LiPo battery and attracts a most of 1.2A with that 3.7V voltage. However wait, there’s extra! The board accepts a PWM sign, so you may finetune the facility to your precise necessities, additionally making the board simply managed by your microcontroller of alternative. The entire challenge can be open-source, with the board recordsdata and instance Python code out there on this Github.

This board was dropped at us by concreted0g from the UK, and I’d extremely suggest having a look at their store. It’s filled with different intelligent merchandise, designed with rocketry and aeronautics initiatives in thoughts, however I might think about plenty of makes use of for this Drop Pin Change.
