[EVDL] Roland Wiench

[Suhas Malghan via EV]

Add me to the long list of people who will miss Roland Wiench’s posts.  I 
enjoyed hearing about his robust approach to engineering informed by data 
collection built around his daily drive. The way he described it, his EV had a 
switch for everything; all failure modes were addressed, regardless of how 
remote their occurrence. It appears he lived a long, satisfying life and I’m 
glad he posted to this list.

Similarly, I have 3 built boards using the nicer Potter & Brumfield relays 
along with the control board in an aluminum enclosure.  I don’t have a 
conversion anymore so let me know if you’re interested, I’ll be happy to see 
the system put into commission.
