Subpage for VemsExecutives
Because of time pressure ( WBO2 , display, ArmEfi design ):
- Marcell Gal is casedesign executive
- Fero (Ferenc Kulin) is vice executive
Prepared
- 500 round cases ordered, will be manufactured any day now. Main issues:
- outer dia is min 51.8 .. max 51.9mm
- total height of the assembled board: 12mm seems to be worstcase (BA56-126GWA display), so 13 .. 15mm internal space should be very safe (17mm in first batch, and even more available with glue instead of endplate).
- a few types can be made, eg.:
- 350 with full-round plexi window (harder to get wrong)
- 150 with 36*17mm (centrally positioned) rectangular plexi window. Also 9xdia=3.1mm for throughole LEDs and 1xdia=5.1mm for pushbutton (Jorgen defined the coordinates in dxf in Smalldisplay_case.zip file).
- 500+ pushbutton caps with appr. 5mm dia, 9.5 .. 10mm total height and slightly rounded top.
- any number of rectangular and round plexi frontplates and endplates, in 3 colors: fully transparent, reddish and green-darkgrey-ish color. These are cheaper than the Al case, so not a problem if there is some excess quantity
- everything is ready for the manufacture of cases based on 120x40x2.5mm profile
- somewhat delayed because of main-connector struggle at VemsExecutives/HardwareDesign. However it is likely that EC36 will be used anyway on some boards, like CDI, so manufacturing frontplates wouldn't hurt. Endplates will be needed for everything, that's little risk.
Plan
- I haven't found many reasonable places to cast the small dongle "case"
- however I found an PCI Apogel-E 2-component elastic stuff that should be suitable. Unfortunately very low viscosity before polymerizing.
- for 1-piece (CNC-ed) negative, the top surface must be flat. It would be a futuristic spaceship-like shape
- for 2-piece (CNC-ed) negative, there is some more shape freedom but more complexity too
- in any case, it will be interesting job to prevent leaking at the meeting point of the WBO2 connector and the negative
- wait for final decision on connector and placement (responsible is VemsExecutives/HardwareDesign ). Besides the EC36, the SAAB70 is also a candidate, although not sure how it fits, since the SAAB70 is wider than 120mm externally. For the IonSense/CDI board the EC36 seems like a better candidate
Candidates - for future
- Kulin Ferenc (MembersPage/Fero) (40 hrs/month)
- Rob Humphris (? hrs/month)
- Jörgen Karlsson. Good knowledge about the tools and procedures, good sense for the mechanical function of the finished product and cost for the solution. Fair sense of the estetics. But I'm not close to our current manufacturing facility and do not use the same primitive tools (like using Corel draw to make the parts.) as the manufacturing facility we are currently using. (40hrs/month)
