Dr Lucy Rogers has put together a great tutorial for those who like their projects smokin’!
She’s taken a Raspberry Pi, some pieces of plastic tubing, some Neopixels, some speakers for the ‘cracking’ sound and an electronic cigarette and created some totally legal fake firecrackers. The total build cost is about £185, but she reckons there are some savings to be made. The whole thing is controlled with her favourite language, Node-RED and you can see the flow on GitHub. The full tutorial is available here and you can see a demo of it working below:
