HF LED Power Accessories

I can post this in a new thread as to not derail this one if needed.

I know a lot of you have been trying to find a way to make a bracelet that will make the blinkys blink. I have been thinking of alternative ways to light up my arm. These are my ideas so far.

If any are blatantly wrong, let me know. (Still Learning, just making a shopping list for payday) I am just trying to come up with a good first project for me. (To go along with my KBR build)

Would it be possible to hook this to an external power supply? Not specifically this one,

But maybe this one also,

I may not be computer savvy, but I am art savvy (to a point) and I feel I could make it look alright for me to wear with some changes, like casting it in resin with maybe a few more led’s to light up, or just cast in resin with a basic design as to not detract from the xLED. Could also maybe use it to program a light show? Maybe even hook it to a mic for music induced light shows.

I wasn’t sure if I could hide it in something like this, but I would sew my own with raw denim likely.

Also, unless I am misunderstanding it, could I not just cut the middle out of this one, and put it around the implant with it inside (like a picture frame)?

I know I could cast that to look nice in resin.

If this is too off subject, let me know and I will relocate it.
