It’s been a while since I’ve had to remember wiring, soldering, & basic DC stuff. Luckily the prefab LED light strips come prewired & with rather obvious + and – polarity indicators on the printed circuit boards, so it’s just really up to me to ensure I get the polarity (of the neutron flow!) correct.
Dissapointment number two with regards to the LED purchase is the number of defective LED strips that Jaycar sold me. I’d already opened and chopped up to size the strips, so no hope of getting a refund there. Had I looked closer and took notice when I opened each sealed pack, it would have jumped out at me that a couple of packs were already opened and taped back up (instead of being heat sealed), and the PCB solder points looked like somebody had already had a go. Damn.
Still dealing with disappointment number one (being short sent a good number of strips) and still waiting for the balance to arrive. I’ve powered up as I’ve gone along to make sure that (barring defective strips) at least I’ve got the wiring correct.
