Wow thanks everyone! I wasn't expecting an article posted about my little project.
@arcol suggested that I should use different colours for the input and output terminals, which is a great idea, I didn't realise there were different colours in the same type. He also suggested using spring terminals and having two different locations to be able to wire the DC out into, both which I'll be looking into in the near future.
@bogdan noted, rightly, that the rectifier will get warm pretty quickly, which is correct. He suggested using active rectification to reduce the amount of heat produced in the process of getting a DC signal out. I hadn't heard about this before, so I was intrigued. It looks like you can use a couple of MOSFETs to perform the same role. Two downsides that I can see for this are, first, added complexity. This shouldn't be a problem, just something I need to wrap my head around! The second is the Vgss value on whatever MOSFET I choose, I need to make sure that it is capable of handling the voltages that I would like the ESPLux to handle. Alternatively I should be able to throw a zener diode in to drop the voltage to an acceptable level. I am super keen to have a shot at getting this working, it'll increase the number of lights that you can run on one unit.
Thanks again for everyone who has followed me in the past 24 hours, I'm chuffed at the amount of people who are interested in it!
