• Low current issues

    I am currently having an issue where the pendent is drawing such low power (designed that way so that it would run all night) that the power bank is shutting off after 30 seconds because it thinks it is not in use. I have seen some people open their battery banks and replace the monitoring resistor, however these are lithium ion batteries and I don't want to do the embarrassing thing of having my pocket explode on fire at a party. What a social faux pas that would be.

    I am considering opening up a USB wire and adding a resistor into the VCC cable to draw some more power. If anyone has any suggestions on how to do this well, or other avenues to take, please let me know!

    I want to wear something glowy and cool to Friday's Surrealist party, so I thought a glowing eye pendant would be right on the money.

    By etching different images into the different layers of acrylic I think I can give an effect of having a pair of eyes follow you as you move around

    I have a bunch of led strips left over from a massive LED project, so I decided to use these strips. Using 1/8 inch thick acrylic and 4 layers, I can use a gear shape on the center two layers to hold the LEDs, while using the front and back layers to hold them in place as full circles. Two outlines of black acrylic 1/4 inch goes around the outside to hold the whole thing in place. Screw holes hold the layers together and bind the inside to the outside.

    I am using an LED controller purchased by Jopel to drive it, since I'm on too short of a schedule to whip up my own. Plus this controller is USB powered, which is great for running it on power banks.

    Here's how it went so far!
