Hi Eric >I've been following the recent discussion about TRIACs, SCRs, Zero crossing >detection, etc. Most of it went over my head but I did pick up a little. SNIP I just noticed today in an SGS Thompson publication that they are making triacs with built in transient suppresion that can be driven directly from a microcontroller. They are even making small ones in arrays of 4 in a package. May be worth checking out. Good luck with the house. Jim
