 The result is the **JRTwine Crowbar Circuit** device.  And while it does not technically bulletproof an AR-II, it can help prevent things from going too badly if the voltage regulator fails.  It also has other applications - anywhere you want to help protect a low voltage circuit from being damaged by overvoltage conditions. The result is the **JRTwine Crowbar Circuit** device.  And while it does not technically bulletproof an AR-II, it can help prevent things from going too badly if the voltage regulator fails.  It also has other applications - anywhere you want to help protect a low voltage circuit from being damaged by overvoltage conditions.
  
-I am currently testing out different applications with different people right now.  The goal is to sell the device as either a bare PCB board, or as a kit containing the following components:+I am currently testing out different applications with different people right now.  The goal is to sell the device as either a bare PCB board, or as a partial kit containing the following components:
   * MC3423 IC   * MC3423 IC
-  * 4-Pin Socket+  * 8-Pin Socket
   * 2N6505 SCR   * 2N6505 SCR
-  * Fuse holder or fuse clips (depending on supply)+  * Fuse holder or fuse clips (depending on supply, maybe optional?) 
 +(Customers will have to provide their own resistors and LED.) 
 + 
 +I figure a target of around $10 works for the kit, and maybe $3-4 for just the PCB?  Dunno if I want to be selling assembled units.
