I'm thinking of a design to improve the electronics in a device like the Milaana, with a contained LiPo pack instead of 18650s, and a regulator for the coil. But I'm not sure where to start. Does anyone sell a heating element that could be used for a ground-up design? I feel like just buying an older/broken vaporizer (like a Milaana, or one of the older Firewoods) and using it for the housing and heater would be an easier route. Would appreciate any suggestions!
