I thought in a transistor controlled by RA4. Shouldn't there be a voltage regulator there somewhere? When the circuit is on, the 16C71 will get almost 9 volts to Vdd. RA4 should be fine, but I don't think 16C71's come in a version rated for 9 volts. > Please take a look in the attached file (just 2K) and say if it's safe.

You need a voltage regulator after the transistor. I'm afraid I don't do transistor designs often enough to tell you if the resistors have reasonable values, or if the transistor is in right. > Regards, > Octavio > ====================================================== > Octavio Nogueira - e-mail: nogueira@mandic.com.br > http://www.geocities.com/~oct_nogueira > "ProPic" Production PIC Programmer Windows under US$20 > ====================================================== > -- paulh@hamjudo.com http://www.hamjudo.com The April 97 WebSight magazine describes me as "(presumably) normal".
