I was at the NMRA British Region Convention last weekend and picked up a pile of tips such as using really really small LEDs (from ebay). I bought a pile and I can’t even see one lot – goodness knows how I’ll solder those. Thankfully most of them are bit larger! I’m going to swap some of the Transformers’ LEDs over to them.
These are by far the smallest. Wow, my smallest soldering iron bit is wider than these!
These are the size I was expecting!
