[dorkbotpdx-blabber] where to get and learn about solenoids

[Donald Delmar Davis]

Greg,

I am testing a set of 12 volt solenoids that I bought at surplus  
gizmos after our previous email exchange.

  I plan to use the spare board from the unipolar stepper drivers for  
the bike meter project since each coil of a unipolar stepper motor  
looks like a solenoid to transistor man.


I will post some video in the next day or two.

In general a darlington like a tip 120 will do the job. And if you can  
find solenoid valves pnumatics are really the way to go.

I am sure that the EEs in the crowd will have some things to add here.

Don aka feurig.
