How would I trigger this from an Arduino running Octobanger (buttonbanger.com)? I've got it working fine with the PIR directly connected to the Pi but would like to insert the Arduino in the path so it can handle playing an ambient attract mp3. Then, when the PIR on the Arduino triggers it can let the Pi know to play the video while it handles signals to the relays to control the Monster in a Box lit solenoid, lights, and fog. I've tried hooking it up with the Arduino/Octobanger using Trigger Low out to the Pi on the same pin as the PIR but the video loads up and immediately starts to play and loops.

Excellent Instructable. I thought only ABS could be solvent smoothed. I'm definitely going to give PLA solvent smoothing a try now. I found a tip online that recommended using silicone basting brushes when applying XTC/Epoxy coatings. It works really well for larger pieces and since it's silicone and nothing sticks to silicone, you just let it dry and then pull it right off and have a clean brush ready to use again. They definitely don't work well for detail areas but for larger areas they're great. I also use a silicone bakers tray for making chocolate squares 1" x 1" x 3/4" as my mixing bowls. Keeps you from making too much at once and you can just move on to the next square for the next batch. Then just let it dry and pop out the left over residue. Lather, Rins...

HI Abzza, Great Instructable. Very well written and detailed. Excellent job! I had have a question and read through the comments searching to see if it had been asked but did not find it so forgive me if I overlooked it. Have you considered a version of this with dual output? Basically a dual mode device where you can feed same voltage to both sides or one voltage for one side and another for the other side (if needed). Situations like this don't always come up but I recently had a project needing 24v and 12v so that project came to mind while reading your Instructable.

How does that $3 version change the voltage output? From looking at the pic it seems like its the pot at the top of the board opposite side of the display. Abzza's intent was to remove the need for using a pot and having to find the right spot for each voltage. Just flip the proper dip switch and done. I can't argue with $3 though. It doesn't plug directly into the breadboard but cheap is always good :D
