The Jeffrey 2.1 PCB for the iSpindel. Please head over to www.OpenSourceDistilling.com/iSpindel for an in depth description, parts list, instructions, and video tutorials.

Minor improvements are completed on The Jeffrey 2.1. On the front I have changed the TP4056 footprint so that the two clusters of two-solder points are designed in such a way that they hold the pins in place for you while soldering. I found that sometimes it was difficult to solder these pins in place as they kept moving and didn't fit in a breadboard. These newly placed through holes should make assembly a little easier.

On the back there are a few changes as well. The 230k resistor typo from the official iSpindel web page has been corrected to 220k. Previously there was a V formation and an additional elongated through-hole allowing two resistors to be added together to get to 230k but since that isn't actually necessary it has been removed.

The Jeffrey 2.1 incorporates a movable battery holder allowing you to balance your iSpindel to 25° tilt in pure water. When installing the battery start with the lowest possible position first as I've found this should get you to 25° tilt without the need to add additional weights. However, there is a spot for weights if they are needed.

Sincerely,
