You run another risk.. the thing that smoked might have changed its characteristics compared to a 'new' one. Can make a mess of cut-and-try design.

It wasn’t the circuit. And just bread-boarding stuff, so if something breaks it gets junked!

Nothing in the semi world gets hot enough to cause smoke without some damage. Revisit your circuit. If it hasn't failed yet, it will.

Your biggest risk is a hookup error, or possibly ESD damage to the Arduino from mishandling. -- You received this message because you are subscribed to a topic in the Google Groups "neonixie-l" group.
