SkyPi

Açıklama

Introducing the SkyPi!Built off the idea of a cheap meshtastic antenna, the SkyPi is a Raspberry Pi Pico 2W based hot air balloon.This balloon is designed to harbor as much space as possible for modular expansion - ever wanted your own weather balloon, without all the crazyness required for a real one? You're in the right place!Powered by birthday candles, one can reach heights usually requiring thousand dollar antennas towers for less than a tank of gas! (but what isnt these days).Current model is in active development, and as such is only able to achieve relatively low lift (With the weight of the wire only rises about a foot off the ground), and has no support for altitude control.Blend file is included, and remixes encouraged! Id love to see what can reasonably be mounted on a passive aircraft like this.Build InstructionsBuild ComponentsPico 2WThinnest plastic garbage bag you can find, current design expecting dimensions ~100cm tall, 60cm diameter (Although I have had some success fusing 2 bags together with light heat)3 ~2.25mm diameter birthday candles~2m 18awg wireA way to supply 5v powerOptional ComponentsTower Pro SG90 Servo (Lift control)*LoRa module (Long range communication)*Altimeter Module (Height control)*Temperature/humidity sensor (Weather station)*Software StepsFlash the Pico 2W with the latest version of CircuitPythonUpload the provided Code.py to the PicoOptionally ensure everything went properly by checking for wifi network SkyPi after rebooting the…
