Assembling and testing of prototype.
redesigned micromanipulator knobs and printed them
re-assembled the micromanipulators with the new knobs and inverted lead screws
re-assembled the micromanipulators with the new knobs and inverted lead screws
re-designed the Active Support part and the Active Bracket part to accomodate the new bigger motor, and re-printed them
Entered 3D printing and assembly info in the PV Characterization - Assembly, troubleshooting and repairs manual https://docs.google.com/document/d/1o1QAPUSpa7ntSQFpd5Np_rYqoh94Js8wzjdhpOLJxOM/edit#
Printed the Arms of the new and improved Clamp design, and the Hands parts also.
In PLA with better tolerances and better Slicing program
3D printed the 3 micro-manipulators in black PLA with some improvements to the design, some new tolerance tweaking and sliced with a new 3D printing program that generates smarter tool path.
3D printed new Bracket that holds the new Clamp with holes for the IMU, and the bottom part of the Clamp
3D printed 2 feet for the new Gimbal and 2 L-shaped brackets
Redesigned the gimbal with 2 support ''Feet'' to compensate for the weight of the gimbal. Ans with 2 L-shaped Brackets. Rounded the corners of the whole gimbal design
I assembled the micromanipulator prototype previously 3D printed, with the screws I bought from the local store.
3D modeled and printed new design of the micromanipulator with metal rods for linear axis. The plastic pars have V-grooves tight on the parallel rods. Ththere still was some tolerance adjustment but it's simple to do comparing with the previous design.
Assembled the Gimbal with newly redesigned and 3D printed parts
Printed revised Gimbal parts, some 3D modelling involved
I've been 3D printing parts since Monday (now we're Thursday)
So I used my failed parts for checking tolerances and I figured out best orientation and printing parameters for each part. I also tested some of the parts for stress and twist resistance and made some adjustments to dimensions and wall/infill/patterns.
I don't have any footage because I lost my phone and I'm waiting for the next pay.
Built working servo based prototype and updated code to work with the hardware

Shopping for parts for the first PV characterization prototype.
Went to deliver package to FEDEX with Jim. Used my car.
Went to deliver package to FEDEX with Tibi. Used Tibi`s car.
Went to the store to buy spray paint for the prototype, recommended by Jim.
was looking for a local store with all kinds of metric screws we need for the gimbal and micromanipulators. Went out to Home Depot and didn't find, walked through few stores until one man referred THE store for screws. Went there with my list of screws and bought everything for 12$ (payed by Tibi). Then I assembled the micromanipulator .
I bought some Black PLA-PHA filament from the local store ($39.95 + tax)
All work related to mechanical prototyping.
Inspection, refinement and assembly of micromanipulators, sample clamp.
Painting of parts with robber spray.
Helped in the design of the sample box.
Assisted Daniel for 3D printing other parts that needed refinement.
worked with Daniel on the redesign of Gimbal parts. We solved the weight balance and the 2 points support for the main gimbal arm.
Daniel is implementing this in the design
