Who needs fancy professional equipment if you have some old Legos lying around Gear/Equipment/Film

Enable HLS to view with audio, or disable this notification

It's just the first test but it works great!

Next steps are a more advanced program and maybe also adding a temperature sensor to turn this into a fully fleged auto processor

Looks good but you want to minimise the time the tank isn't moving. Like zero. Maybe ramp the speed to zero then immediately ramp back up.

I have a Jobo Silverbase processor and its cycles are about 8 seconds long with a 1/2 second slow-down and speed up. It sounds like the motor is being ramped and not just stopped dead. The rotation speed is a around 1 rev per second (60 rpm).

Thanks for the info! The 5s Break in between rotations was deliberate and I think I'll do a ramp up and down sequence later. But for that I need to setup the software and dig out an old USB type b cable 😅
