Watchdog system (Tanaka)
Past week report
- I'm working on design drawing for cutting of 19'rack front panel(4ch WDS Main box)(Continue as last week).
Drawing both for external ordering and for CNC Milling machine(Numerical control program(G-code)). PDF(JGW-E1706302)
- Electronic parts ordered from co-op(Univ.Tokyo) have not come yet(Has not come yet!!).
Plan for coming weeks
- Design for processing(Continuation).
Pending ---> I'm planning to perform surface mounting for Power board(WDS Main 4ch Box) in reflow furnace in Akihabara.Since a large PCB size( 320mm * 100mm) is required,a large reflow furnace is necessary,so it can be borrowed in Akihabara(DMM-make site.And of course,paid).
