    Remote Controlled IKEA Death-Star Lamp

    Hi,That's an interesting find, but I can see why it would be difficult for a small DC motor to pull. The pitch is 4 times greater than the standard M3 rod that I used so it would require 4 time more strength. Perhaps a stepper motor would be strong enough? I discarded a stepper as being too slow, but with this rod that would not be an issue. A big enough motor, DC or stepper, would do it, but as you say, the lamp gets in the way. In that case, can you change the lamp to something with a lower profile? Maybe with multiple smaller laps around the motor?You will probably experience a wobbling effect with any rod. Of course, the thinner the rod and the faster it spins the bigger vibrations you'll get. But the problem with the thicker rod is that it would be harder for the motor to spin it. ...

Of course, the thinner the rod and the faster it spins the bigger vibrations you'll get. But the problem with the thicker rod is that it would be harder for the motor to spin it. Basically, you'll end up in the same situation. I've done a bit of testing with M3, M4 and M5 screws on pull strength and I were convinced that M3 was my best option. But your mileage may warry.As for the long M3 nut, how about this one http://www.ebay.co.uk/itm/HIGH-HEX-CONNECTION-NUTS-HEXAGON-CONNECTOR-CONNECTING-ROD-BAR-STUD-LONG-NUT-ZINC/122394731129?hash=item1c7f4b6279:m:m1bud2igM0wM7Iw1yZwYOAQPlease be aware that some of the sizes come in 2 way only (blocked in middle), as it is written in the description. In that case, simply chop it in a half. Of course, make sure you buy the nut at least twice as long as you need.

    Remote Controlled IKEA Death-Star Lamp

    Hi RogierH1, yes I had to enlarge the hole using a drill. The screw you see in the photo only touches the shaft of the potentiometer and holds it in place. Also, you might notice a piece of cardboard used around the shaft to center it as the hole was a bit too big. On the other side, the potentiometer itself (covered with white tape) is secured to a small piece of PCB that is screwed in to the side of the green part. Sadly, I did not take any pictures at the building stage so that part is not visible.

    Smart Mirror Using Broken Android Tablet

    I had the same concern, but turns out Android Studio installs application when running on device. I just need to connect USB cable to it. Oh, and I had to enable development mode on the tablet itself. Of course, I kept the touchscreen just in case I have issue I cannot resolve via code, like time settings.Indeed, no one can tell there is a camera. That will be my little secret :)

    Thanks. For power I just used standard mini USB charger contantly plugged in.
