Researching buck boost circuit implementation.
3D printer research, CAD, and file organization.
working on circularknitic mountain, went down a dead end for a few hours, then started back up and worked on basic form without the groove path.
Experimented with debugging of FreeCAD scripts. Wrote documentation on OSE wiki.

learning how to implement PWM controller IC for buck-boost converter
including 6 hours on redesign of filament maker
lecture in Hong Kong
Reorganized tools and re-inventoried; workshop review
To get ABS to stick, spread base of ABS juice (10 acetone:1 ABS). Using foil as substrate to easily remove printed part from bed. Have PEI plastic to cover bed. Crappy prints at 200 C extruder, nicer prints at 225-235.
reflect on 1st workshop
reworked pc v18.01 assembly and narrowed it to fit LT
meeting with Jesse
learning how to connect control IC for buck-boost converter
Workshop @ CCL, Oakland, CA
Working on getting lab 3D printer up and running. It is a Rostock, with 3 axis. ABS material is difficult to get to stick the bed. Will not stick to glass, have tape down but still not sticking. Will try roughing up the tape surface and hairspray. Should have PET sheet somewhere.
got free ABS filament and ordered more PLA. went to test ABS but wire to heater carriage was broken. Ordered replacement from e3d, and a volcano starter kit. kind of expensive replacement parts, will compare shipping speed to folgertech. thinking about how to shield extruder fans and motors from magnets used for mounting. really like the magnetic mounts but needs a better assembly procedure.
