    Use the copper strips, I've been using for a long time and I never got a hairline crack in my finest bits!

    A year later – Where's the kit build video? ๐Ÿ˜€

    Julian, did you ever make the rotating kit? I don't remember ever seeing a video about it.

    One method for installing the LED's onto the curved surface is to use a small amount of glue to connect all the LED's to the curved surface. Once the glue is dry then you could solder all the LED's at one time. Maybe one drop of superglue would work for each LED.

    Another method would be to take two small pieces of wood and clamp them together with the curved PCB between. Place one LED on your work surface and set the curved PCB vertical, just touching the back of the LED at a right angle. This way you could solder each LED by adjusting the curved PCB and your two small clamped wood blocks so the each LED is at 90 degrees when you solder it in place. Just some ideas. Take care.

    The POV stands for persistence of vision not point of view.

    I understand that the wet sponge method of tip cleaning causes micro-cracking of the iron plating on tips such as Weller and have found that the brass swarf cleaner makes my tip last longer – oe-er, Matron!

    On the LED light bar try using a drop of super glue to hold each LED in place before soldering. Just a thought.

    I use a wet natural sponge… I really like it.. I keep my soldering iron somewhat warmer. (no temperature control) so its sometimes rising a bit high.. I cool I down in the damp sponge and it cleans perfectly and when it's dirty I'll wash it out and it's (almost) brand new!

    Regarding the Banggood kit. Why not use double sided tape on the pcb and trim it with a sharp knife (I used scalpel and it works great) then stick and position the smd leds to the tape before soldering. They should stay put if the heat isn't applied for too long.

  12. Avataaar/Circle Created with python_avatars Marcus Jeff says:

    Hello I just watched your video and you look like you need a tool for mounting the led's if you do let me know I might be able to help

    I think the question is, How many times does it rotate 270 degrees ๐Ÿ˜›
