Ok so I bought one of these kits from eBay, which eventually arrived:
https://www.ebay.co.uk/itm/DIY-Green...72.m2749.l2648
Now I soldered everything how I thought was a-ok with my knockoff of a Hakko 936D iron.
However when powering nothing happened at all. Even using a 3V coin cell nothing also happened.
I tried rotating the switch (see centre right) and the cap in the images blew its guts out.
The polarity seems ok as I think that the solid line on the PSU (little 9V 100ma switcher) is the negative which would go to ground?
How do I know which way round the switch goes?
Am I a dummy?
