Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Accomplishments from Previous Week
Call/Email Fuzz Button Company re: Currently in production runs to avoid tooling costs - Harald
Lead times do not allow for project completion in timely fashion (additionally, cost is a factor), FuzzButtons will be added to list of future improvements/manufacturing decisions.
Call/Email DigiKey re: Supply issues and lead times - Harald
Digikey Considered "Critical Sector Infrastructure" and will continue to operate for the foreseeable future, registered to receive updates/notifications in real-time. Additionally, all stock is stored in Minnesota therefore shipping times can be considered accurate.
Digi-Key’s NAICS code is 4236 - Electrical and Electronic Goods Merchant Wholesalers
Finalize Locking Mechanism Design
Choice between 1 Custom and 2 Existing Solutions - Trent/Jesse
Locking mechanism design selected, requires CAD generation
Finalize material choice and contact print houses for estimates - Trent/Jesse
Re3D Tech - https://re3dtech.com/3d-composites/3d-printed-6061-7075-aluminum/
Call/Email for 100x100 plate comps
Considering machine shops as opposed to 3D sintering due to manufacturing constraints and application specific approved materials lists.
Setup Meeting w/Steve Roberts for Monday 4/6/2020 - Leigh/Jesse
Meeting completed, meeting minutes posted below
Initial PCB Design using Eagle/Altium - Leigh/Jesse
PCB Design in initial stages, requires more design constraint information.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
PCB Designed & Sent off for prototyping - Leigh/Jesse
Purchase USB Components - Jesse
CAD Design of Plate - Harald
CAD Design of Locking Mechanism - Trent
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Project will continue as planned with one change
Manufacturing work will likely be conducted offsite by print house/machine shop, depending on final choice of material and manufacturing method.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Consider threadserts or loctite if planning on tapping aluminum threads, however it is not clear whether loctite is an acceptable material for spaceflight.
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
