The very first batch has been made: apple banana coconut sorbet with chocolate oat cookie chunks and roasted soybeans. It took way too long to get a good consistency because of the bad insulation but tasted way too good to not continue with the project. Next step will be a waterproof case with proper insulation and a worm gear drive for the paddle. Then motorizing it with a window wiper motor, a PWM or BAM driver and a microcontroller which monitors everything. I plan to measure the current of the motor and establish a correlation of ice cream consistency and current consumption. With a small LUT (Look Up Table) the controller can then achieve a set consistency and hold it – from slush ice over sorbet up to heavy gelato.
Successfully acquired a leftover fridge from fellow hacker friends, now frankensteining the thing together. Next step: Insulation.
Prototyping a next level ice cream machine because.. ice cream!
First iteration with 1.33l container volume. Now searching for a leftover freezer/fridge from which I could upcycle the compressor and tubing.
In a further iteration I might design a proper spatula which can be mangled through CAD-CAM and then machined on the 3 axis CNC milling machine.
The Open Source Beehives project proposes to design hives that can support bee colonies in a sustainable way, to monitor and track the health and behaviour of a colony as it develops. Each hive contains an open source sensory kit, The Smart Citizen Kit (SCK), which can transmit to an open data platform: Smartcitizen.me
These sensor enhanced hive designs are open and freely available online. I forked the little desktop sized bee hive model, made it metric and CNC laser cutted it for OSBH. It will be displayed at the OuiShare Summit Berlin and advertise the OSBH-workshops which will happen in July.
