$Smart Manual Lever Machine from the Future This is Shays (of caffeinated.science) customized pid controlled open boiler lever espresso machine. With it, the beanconqueror app, and a smart scale, I can record full pressure and output profiles. Pressure profiles are recorded using the Popsicle, a custom built bluetooth pressure transducer designed by Mike and Shay. The Popsicle uses a commonly available automotive pressure transducer coupled to a bluetooth capable board and custom battery management software. Altogether, this is one of the most advanced machines you can get at a fraction of the cost. Shay and Mike are always doing crazy things. Follow Shays blog at https://www.caffeinated.science/ or his instagram: https://www.instagram.com/caffeinated.science/?hl=en Find Mike (@Misha) on https://discord.gg/espresso I highly recommend the BeanConqueror App. Its an easy way to standardize data gathering for coffee brewing and its really helpful if you want to track changes over time. https://beanconqueror.com/ Check out Brian Quans original video if you want to learn more about the Jian-Yi https://www.youtube.com/watch?v=HdobC12eKD4$
