MiniPOV 4 Lights Not Working

Post by otakufreakmonkey »

Hello all,

This is my first Adafruit kit project. I took my time spending a few hours soldering each component and checking my work along the way. Since I'm rather new to soldering I thought this would be a great first project. Everything went smoothly and the device powered up great the first time. The issue I am having it that at first the last light (8) did not come on. Shortly after using it to test the effects, another light (4) turned off. This light (4) would come and go at random times or while I was shaking it back and forth. If I tapped on the LED (4) it would flicker on, but not stay on for very long. I checked the solders, remelted the solders and added a bit more to ensure a good connection, but I still have the same issue. I can apply pressure and sometimes it'll come back on. I've included photos so that my work is shown.

Your joints are not all well soldered. Take a look at this Soldering Guide

Went over all the solder points and followed the tutorial online. Everything works great now. Thanks!

MiniPOV 4 Demo images. Most of these were taken with a 6" exposure and a f-stop of 7 iso 100.
