Hi all: I just built the TAPR 238+ Weather station controller and it seems to be working just fine, except the 5 volt regulator chip is hot. I can put my finger on it, or it's heat sink, but I can't keep it there. I'm feeding it 13.8vdc (my whole shack runs on 13.8 vdc). I was thinking of putting a second regulator, about 9 volt, external and in front of the power connector, so the voltage is knocked down in two steps, so each regulator is sharing the load. Thoughts or suggestions? Sincerely /Blair __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
