Beyond the short answer of, yes probably, I've got a bunch of stuff i'm planning to do that will be pretty big firsts for me. I hope this is a learning experience for me, more so than i hope to actually have a really excellent reflow oven. In fact i may never actually build the oven. Although that would be ok too.
I have a few questions, not sure if i'll keep them all in this thread or make a new thread for each one, but either way, 1 at a time. If a MOD has a preference for that please let me know. The questions will all relate to building thisDeath trap cool peice of lab equipment.
People here consider .pdf's safe? I always have, so thats how I attached the schematic.
First up is the Triac Driver Board. Never used triacs before.
I intend to wire the heating elements, of which most toaster ovens have 2 to a couple triacs. This board will be inside a metal box inside the electronics compartment of the oven, and bonded to the ground wire of the 3-wire plug (i will install one if the toaster i choose doesnt have one).
1. Any thoughts on my schematic?
2. Is it safe to have a zero cross detect wire direct from mains like I have? Should i put a clamping diode between the resistor and the connector to limit this to 5v? I believe i read in my PIC data sheet that the zero cross detect pin can handle high voltages provided you put a huge resistor on it. Although thinking about it just now, i think a 5v diode would be wise...
3. The clamping diode connects to the neutral line?
