There are lots of POV displays out there, lots have multi color LEDs that can display some impressive images. Gelstronic has built this 3D POV Display that has lots of tech going on. The addressable LEDs are setup in strips of varying heights. When spun this allows the display to create 3D images in color. A Parallax Propeller microcontroller powers the main display while an Arduino Pro Mini works with the ESC to keep things turning properly. To get power to the spinning portion of the board a wireless power module is used, this module can get about 10 watts of power through the air gap which is plenty for the LEDs.

Instead of purchasing a new or reconditioned iPhone Scotty from Strange Parts decided to build his own. If he was in any other country this would have been near impossible but he was in China. There are lots of repair and recycling facilities that were able to sell him the bits and pieces that he needed. At 6:15 you can see Scotty purchase the display and digitizer from a repair facility. The parts used are probably not genuine Apple parts but rather the common aftermarket parts that are used to repair the phones if they get damaged and are repaired by a 3rd party vendor. The small shop has some impressive machines including a vacuum chamber that I am thinking a local repair shop would not have. The iPhone logic board is the main control board of the phone and since this is a phone the components are extremely small. He was thinking of purchasing a bare logic PCB and then purchase all of components separately. This would be a crazy undertaking. I think he went the better route which was to purchase a repaired one. With a huge bag of screws in hand and a ton of tiny parts he actually completed the build and now has a working iPhone! |

Steve Marriott wanted to have some automated outdoor lights. They will be controlled by an Arduino that will monitor some PIR sensors to see what is going on and turn lights on based on activity. A few tictac boxes were used to mount the outdoor electronics in. The project changed over time based on community help. The end result is a a completely automated lighting system that looks great and provides a ton of light. |

Instead of purchasing a Tesla Power Wall jehugarcia shows us how a DIY version can be put together. The EV West facility has a large flat roof which makes laying the panels nice and easy. The roof is crazy high so getting them up on the roof looks like it was not that simple. The video at the top shows a bit of the solar panel installation and the lower video is an update on the system showing how the system is wired. This system is basically used to charge EV vehicles but there are some regular outlets that can be used for regular plug in equipment if there is a power failure. The Tesla car batteries are mounted in a standard electrical off the shelf enclosure. There is no continuous battery monitoring on the battery packs but rather a header that a battery balance monitoring system can be plugged into whenever they would like to check the levels. |

If you are looking to have some fun with the network of your big vehicle this video would be fun for you. The CAN bus is probably the vehicle bus that you have heard about but there are many other bus standards that are used when digging into your semi truck. Instead of purchasing a $100,000 truck they built a truck electronic emulation systems.
