+## Example Installations ##
+
+These photos are from snap-ring case forward closures machined by Bdale for
+test flights of EasyMotor.  The sensor bodies are 316 stainless with a 1/8 NPT
+male boss, so the approach chosen is to drill a 1/8 inch touch hole all the
+way through the closure, then drill and tap 1/8 NPT female threads part way
+through the closure thickness.  The hole gets filled with grease and the 
+sensor screwed in.

 ## Artifacts ##
 
+The firmware for this product is part of the [AltOS](../AltOS) suite.
+
 This board was designed using lepton-eda and pcb-rnd.
 
 The hardware design files are available from 
 [git.gag.com](http://git.gag.com) in the project 
 [hw/easymotor](http://git.gag.com/?p=hw/easymotor;a=summary).  
 
+## Availability ##
+
+Prototypes of v2 were built and successfully flown.  An initial production 
+batch is now underway, and we hope these will be for sale around the end of
+calendar year 2020.
